- PublicaciónAcceso abiertoAssociation of bedtime with mortality and major cardiovascular events: an analysis of 112,198 individuals from 21 countries in the PURE study(Elsevier, 2021-04-05) Wang, Chuangshi; Hu, Bo; Rangarajan, Sumathy; Bangdiwala, Shrikant I.; Lear, Scott A.; Mohan, Viswanathan; Gupta, Rajeev; Alhabib, Khalid F.; Soman, Biju; Abat, Marc Evans M.; Rosengren, Annika; Lanas, Fernando; Avezum, Alvaro; Lopez-Jaramillo, Patricio; Diaz, Rafael; Yusoff, Khalid; Iqbal, Romaina; Chifamba, Jephat; Yeates, Karen; Zatońska, Katarzyna; Kruger, Iolanthe M.; Bahonar, Ahmad; Yusufali, AfzalHussein; Li, Wei; Yusuf, Salim; The Prospective Urban Rural Epidemiology (PURE) study investigators; MasiraObjectives This study aimed to examine the association of bedtime with mortality and major cardiovascular events. Methods Bedtime was recorded based on self-reported habitual time of going to bed in 112,198 participants from 21 countries in the Prospective Urban Rural Epidemiology (PURE) study. Participants were prospectively followed for 9.2 years. We examined the association between bedtime and the composite outcome of all-cause mortality, non-fatal myocardial infarction, stroke and heart failure. Participants with a usual bedtime earlier than 10PM were categorized as ‘earlier’ sleepers and those who reported a bedtime after midnight as ‘later’ sleepers. Cox frailty models were applied with random intercepts to account for the clustering within centers. Results A total of 5633 deaths and 5346 major cardiovascular events were reported. A U-shaped association was observed between bedtime and the composite outcome. Using those going to bed between 10PM and midnight as the reference group, after adjustment for age and sex, both earlier and later sleepers had a higher risk of the composite outcome (HR of 1.29 [1.22, 1.35] and 1.11 [1.03, 1.20], respectively). In the fully adjusted model where demographic factors, lifestyle behaviors (including total sleep duration) and history of diseases were included, results were greatly attenuated, but the estimates indicated modestly higher risks in both earlier (HR of 1.09 [1.03–1.16]) and later sleepers (HR of 1.10 [1.02–1.20]). Conclusion Early (10 PM or earlier) or late (Midnight or later) bedtimes may be an indicator or risk factor of adverse health outcomes.
- PublicaciónAcceso abiertoAssociation of Sitting Time with Mortality and Cardiovascular Events in High-Income, Middle-Income, and Low-Income Countries(2022-06-15) Li, Sidong; Lear, Scott A.; Rangarajan, Sumathy; Hu, Bo; Yin, Lu; Bangdiwala, Shrikant I.; Alhabib, Khalid F.; Rosengren, Annika; Gupta, Rajeev; Mony, Prem K.; Wielgosz, Andreas; Rahman, Omar; Mazapuspavina, M. Y.; Avezum, Alvaro; Oguz, Aytekin; Yeates, Karen; Lanas, Fernando; Dans, Antonio; Evans, Marc; Abat, M.; Yusufali, Afzalhussein; Rafael, Diaz; Lopez-Jaramillo, Patricio; Leach, Lloyd; Lakshmi, P. V. M.; Iqbal, Romaina; Kelishadi, Roya; Chifamba, Jephat; Khatib, Rasha; Li, Wei; Yusuf, Salim; MasiraImportance High amounts of sitting time are associated with increased risks of cardiovascular disease (CVD) and mortality in high-income countries, but it is unknown whether risks also increase in low- and middle-income countries. Objective To investigate the association of sitting time with mortality and major CVD in countries at different economic levels using data from the Prospective Urban Rural Epidemiology study. Design, Setting, and Participants This population-based cohort study included participants aged 35 to 70 years recruited from January 1, 2003, and followed up until August 31, 2021, in 21 high-income, middle-income, and low-income countries with a median follow-up of 11.1 years. Exposures Daily sitting time measured using the International Physical Activity Questionnaire. Main Outcomes and Measures The composite of all-cause mortality and major CVD (defined as cardiovascular death, myocardial infarction, stroke, or heart failure). Results Of 105 677 participants, 61 925 (58.6%) were women, and the mean (SD) age was 50.4 (9.6) years. During a median follow-up of 11.1 (IQR, 8.6-12.2) years, 6233 deaths and 5696 major cardiovascular events (2349 myocardial infarctions, 2966 strokes, 671 heart failure, and 1792 cardiovascular deaths) were documented. Compared with the reference group (<4 hours per day of sitting), higher sitting time (≥8 hours per day) was associated with an increased risk of the composite outcome (hazard ratio [HR], 1.19; 95% CI, 1.11-1.28; Pfor trend < .001), all-cause mortality (HR, 1.20; 95% CI, 1.10-1.31; Pfor trend < .001), and major CVD (HR, 1.21; 95% CI, 1.10-1.34; Pfor trend < .001). When stratified by country income levels, the association of sitting time with the composite outcome was stronger in low-income and lower-middle–income countries (≥8 hours per day: HR, 1.29; 95% CI, 1.16-1.44) compared with high-income and upper-middle–income countries (HR, 1.08; 95% CI, 0.98-1.19; P for interaction = .02). Compared with those who reported sitting time less than 4 hours per day and high physical activity level, participants who sat for 8 or more hours per day experienced a 17% to 50% higher associated risk of the composite outcome across physical activity levels; and the risk was attenuated along with increased physical activity levels. Conclusions and Relevance High amounts of sitting time were associated with increased risk of all-cause mortality and CVD in economically diverse settings, especially in low-income and lower-middle–income countries. Reducing sedentary time along with increasing physical activity might be an important strategy for easing the global burden of premature deaths and CVD.
- PublicaciónAcceso abiertoAssociations of Fish Consumption with Risk of Cardiovascular Disease and Mortality among Individuals with or without Vascular Disease from 58 Countries(JAMA Network, 2021-03-08) Mohan, Deepa; Mente, Andrew; Dehghan, Mahshid; Rangarajan, Sumathy; O’Donnell, Martin; Hu, Weihong; Dagenais, Gilles; Wielgosz, Andreas; Lear, Scott; Wei, Li; Diaz, Rafael; Avezum, Alvaro; Lopez-Jaramillo, Patricio; Lanas, Fernando; Swaminathan, Sumathi; Kaur, Manmeet; Vijayakumar, K.; Mohan, Viswanathan; Gupta, Rajeev; Szuba, Andrzej; Iqbal, Romaina; Yusuf, Rita; Mohammadifard, Noushin; Khatib, Rasha; Yusoff, Khalid; Gulec, Sadi; Rosengren, Annika; Yusufali, Afzalhussein; Wentzel-Viljoen, Edelweiss; Chifamba, Jephat; Dans, Antonio; Alhabib, Khalid F.; Yeates, Karen; Teo, Koon; Gerstein, Hertzel C.; Yusuf, Salim; The PURE, ONTARGET, TRANSCEND, and ORIGIN investigators; MasiraImportance Cohort studies report inconsistent associations between fish consumption, a major source of long-chain ω-3 fatty acids, and risk of cardiovascular disease (CVD) and mortality. Whether the associations vary between those with and those without vascular disease is unknown. Objective To examine whether the associations of fish consumption with risk of CVD or of mortality differ between individuals with and individuals without vascular disease. Design, Setting, and Participants This pooled analysis of individual participant data involved 191 558 individuals from 4 cohort studies—147 645 individuals (139 827 without CVD and 7818 with CVD) from 21 countries in the Prospective Urban Rural Epidemiology (PURE) study and 43 413 patients with vascular disease in 3 prospective studies from 40 countries. Adjusted hazard ratios (HRs) were calculated by multilevel Cox regression separately within each study and then pooled using random-effects meta-analysis. This analysis was conducted from January to June 2020. Exposures Fish consumption was recorded using validated food frequency questionnaires. In 1 of the cohorts with vascular disease, a separate qualitative food frequency questionnaire was used to assess intake of individual types of fish. Main Outcomes and Measures Mortality and major CVD events (including myocardial infarction, stroke, congestive heart failure, or sudden death). Results Overall, 191 558 participants with a mean (SD) age of 54.1 (8.0) years (91 666 [47.9%] male) were included in the present analysis. During 9.1 years of follow-up in PURE, compared with little or no fish intake (≤50 g/mo), an intake of 350 g/wk or more was not associated with risk of major CVD (HR, 0.95; 95% CI, 0.86-1.04) or total mortality (HR, 0.96; 0.88-1.05). By contrast, in the 3 cohorts of patients with vascular disease, the HR for risk of major CVD (HR, 0.84; 95% CI, 0.73-0.96) and total mortality (HR, 0.82; 95% CI, 0.74-0.91) was lowest with intakes of at least 175 g/wk (or approximately 2 servings/wk) compared with 50 g/mo or lower, with no further apparent decrease in HR with consumption of 350 g/wk or higher. Fish with higher amounts of ω-3 fatty acids were strongly associated with a lower risk of CVD (HR, 0.94; 95% CI, 0.92-0.97 per 5-g increment of intake), whereas other fish were neutral (collected in 1 cohort of patients with vascular disease). The association between fish intake and each outcome varied by CVD status, with a lower risk found among patients with vascular disease but not in general populations (for major CVD, I2 = 82.6 [P = .02]; for death, I2 = 90.8 [P = .001]). Conclusions and Relevance Findings of this pooled analysis of 4 cohort studies indicated that a minimal fish intake of 175 g (approximately 2 servings) weekly is associated with lower risk of major CVD and mortality among patients with prior CVD but not in general populations. The consumption of fish (especially oily fish) should be evaluated in randomized trials of clinical outcomes among people with vascular disease.
- PublicaciónAcceso abiertoAvailability and affordability of medicines and cardiovascular outcomes in 21 high-income, middle-income and low-income countries(BMJ Journals, 2020-11-05) Chow, Clara Kayei; Nguyen, Ngoc; Marschner, Simone; Diaz, Rafael; Rahman, Omar; Avezum, Alvaro; Lear, Scott A.; Teo, Koon; Yeates, Karen; Lanas, Fernando; Li, Wei; Hu, Bo; Lopez-Jaramillo, Patricio; Gupta, Rajeev; Kumar, Rajesh; Mony, Prem; Bahonar, Ahmad; Yusoff, Khalid; Khatib, Rasha; Kazmi, Khawar; Dans, Antonio; Zatonska, Katarzyna; Alhabib, Khalid F.; Kruger, Iolanthe Marike; Rosengren, Annika; Yusufali, Afzalhussein; Chifamba, Jephat; Rangarajan, Sumathy; McKee, Martin; Yusuf, Salim; MasiraObjectives We aimed to examine the relationship between access to medicine for cardiovascular disease (CVD) and major adverse cardiovascular events (MACEs) among people at high risk of CVD in high-income countries (HICs), upper and lower middle-income countries (UMICs, LMICs) and low-income countries (LICs) participating in the Prospective Urban Rural Epidemiology (PURE) study. Methods We defined high CVD risk as the presence of any of the following: hypertension, coronary artery disease, stroke, smoker, diabetes or age >55 years. Availability and affordability of blood pressure lowering drugs, antiplatelets and statins were obtained from pharmacies. Participants were categorised: group 1—all three drug types were available and affordable, group 2—all three drugs were available but not affordable and group 3—all three drugs were not available. We used multivariable Cox proportional hazard models with nested clustering at country and community levels, adjusting for comorbidities, sociodemographic and economic factors. Results Of 163 466 participants, there were 93 200 with high CVD risk from 21 countries (mean age 54.7,49% female). Of these, 44.9% were from group 1, 29.4% from group 2 and 25.7% from group 3. Compared with participants from group 1, the risk of MACEs was higher among participants in group 2 (HR 1.19, 95% CI 1.07 to 1.31), and among participants from group 3 (HR 1.25, 95% CI 1.08 to 1.50). Conclusion Lower availability and affordability of essential CVD medicines were associated with higher risk of MACEs and mortality. Improving access to CVD medicines should be a key part of the strategy to lower CVD globally.
- PublicaciónAcceso abiertoContrasting associations between diabetes and cardiovascular mortality rates in low-, middle-, and high-income countries: Cohort study data from 143,567 individuals in 21 countries in the pure study(American Diabetes Association, 2020-10-15) Mohan Anjana, Ranjit; Mohan, Viswanathan; Rangarajan, Sumathy; Gerstein, Hertzel C.; Venkatesan, Ulagamadesan; Sheridan, Patrick; Dagenais, Gilles R.; Lear, Scott A.; Teo, Koon; Karsidag, Kubilay; Alhabib, Khalid F.; Yusoff, Khalid; Ismail, Noorhassim; Mony, Prem; Lopez-Jaramillo, Patricio; Chifamba, Jephat; Palileo-Villanueva, Lia M.; Iqbal, Romaina; Yusufali, Afzalhussein; Kruger, Iolanthe M.; Rosengren, Annika; Bahonar, Ahmad; Zatonska, Katarzyna; Yeates, Karen; Gupta, Rajeev; Li, Wei; Hu, Lihua; Rahman, M. Omar; Lakshmi, P.V.M.; Iype, Thomas; Avezum, Alvaro; Diaz, Rafael; Lanas, Fernando; Yusuf, Salim; MasiraOBJECTIVE We aimed to compare cardiovascular (CV) events, all-cause mortality, and CV mortality rates among adults with and without diabetes in countries with differing levels of income. RESEARCH DESIGN AND METHODS The Prospective Urban Rural Epidemiology (PURE) study enrolled 143,567 adults aged 35–70 years from 4 high-income countries (HIC), 12 middle-income countries (MIC), and 5 low-income countries (LIC). The mean follow-up was 9.0 6 3.0 years. RESULTS Among those with diabetes, CVD rates (LIC 10.3, MIC 9.2, HIC 8.3 per 1,000 personyears, P < 0.001), all-cause mortality (LIC 13.8, MIC 7.2, HIC 4.2 per 1,000 personyears, P < 0.001), and CV mortality (LIC 5.7, MIC 2.2, HIC 1.0 per 1,000 person-years, P < 0.001) were considerably higher in LIC compared with MIC and HIC. Within LIC, mortality was higher in those in the lowest tertile of wealth index (low 14.7%, middle 10.8%, and high 6.5%). In contrast to HIC and MIC, the increased CV mortality in those with diabetes in LIC remained unchanged even after adjustment for behavioral risk factors and treatments (hazard ratio [95% CI] 1.89 [1.58–2.27] to 1.78 [1.36–2.34]). CONCLUSIONS CVD rates, all-cause mortality, and CV mortality were markedly higher among those with diabetes in LIC compared with MIC and HIC with mortality risk remaining unchanged even after adjustment for risk factors and treatments. There is an urgent need to improve access to care to those with diabetes in LIC to reduce the excess mortality rates, particularly among those in the poorer strata of society.

Corrigendum to Association of bedtime with mortality and major cardiovascular events. an analysis of 112,198 individuals from 21 countries in the PURE study(2022-02-05) Wang, Chuangshi; Hu, Bo; Rangarajan, Sumathy; Bangdiwala, Shrikant I.; Gulec, Sadi; Lear, Scott A.; Mohan, Viswanathan; Gupta, Rajeev; Alhabib, Khalid F.; Soman, Biju; Abat, Marc Evans M.; Rosengren, Annika; Lanas, Fernando; Avezum, Alvaro; Lopez-Jaramillo, Patricio; Diaz, Rafael; Yusoff, Khalid; Iqbal, Romaina; Chifamba, Jephat; Yeates, Karen; ZatonskaIolanthe, Katarzyna; Kruger, M.; Bahonar, Ahmad; Yusufali, AfzalHussein; Li, Wei; Yusuf, Salim; Prospective Urban Rural Epidemiology (PURE) study investigators; Masira
- PublicaciónAcceso abiertoGlobal variations in the prevalence, treatment, and impact of atrial fibrillation in a multi-national cohort of 153 152 middle-aged individuals(Oxford Academic, 2021-06-05) Joseph, Philip; Healey, Jeffrey S.; Raina, Parminder; Connolly, Stuart J.; Ibrahim, Quazi; Gupta, Rajeev; Avezum, Alvaro; Dans, Antonio; Lopez-Jaramillo, Patricio; Yeates, Karen; Teo, Koon; Douma, Reuben; Bahonar, Ahmad; Chifamba, Jephat; Lanas, Fernando; Dagenais, Gilles R.; Lear, Scott; Kumar, Rajesh; Kengne, Andre P.; Keskinler, Mirac; Mohan, Viswanathan; Mony, Prem; Alhabib, Khalid F.; Huisman, Hugo; Iype, Thomas; Zatonska, Katarzyna; Ismail, Rosnah; Kazmi, Khawar; Rosengren, Annika; Rahman, Omar; Yusufali, Afzalhussein; Wei, Li; Orlandini, Andres; Islam, Shofiqul; Rangarajan, Sumathy; Yusuf, Salim; The PURE Investigators; MasiraAims To compare the prevalence of electrocardiogram (ECG)-documented atrial fibrillation (or flutter) (AF) across eight regions of the world, and to examine antithrombotic use and clinical outcomes. Methods and results Baseline ECGs were collected in 153 152 middle-aged participants (ages 35–70 years) to document AF in two community-based studies, spanning 20 countries. Medication use and clinical outcome data (mean follow-up of 7.4 years) were available in one cohort. Cross-sectional analyses were performed to document the prevalence of AF and medication use, and associations between AF and clinical events were examined prospectively. Mean age of participants was 52.1 years, and 57.7% were female. Age and sex-standardized prevalence of AF varied 12-fold between regions; with the highest in North America, Europe, China, and Southeast Asia (270–360 cases per 100 000 persons); and lowest in the Middle East, Africa, and South Asia (30–60 cases per 100 000 persons) (P < 0.001). Compared with low-income countries (LICs), AF prevalence was 7-fold higher in middle-income countries (MICs) and 11-fold higher in high-income countries (HICs) (P < 0.001). Differences in AF prevalence remained significant after adjusting for traditional AF risk factors. In LICs/MICs, 24% of participants with AF and a CHADS2 score ≥1 received antithrombotic therapy, compared with 85% in HICs. AF was associated with an increased risk of stroke [hazard ratio (HR) 2.29; 95% confidence interval (CI) 1.49–3.52] and death (HR 2.97; 95% CI 2.25–3.93); with similar rates in different countries grouped by income level. Conclusions Large variations in AF prevalence occur in different regions and countries grouped by income level, but this is only partially explained by traditional AF risk factors. Antithrombotic therapy is infrequently used in poorer countries despite the high risk of stroke associated with AF.
- PublicaciónAcceso abiertoGlycemic index, glycemic load, and cardiovascular disease and mortality(The New England Journal of Medicine, 2021-04-08) Jenkins, David; Dehghan, Mahshid; Mente, Andrew; Bangdiwala, Shrikant I.; Rangarajan, Sumathy; Srichaikul, Kristie; Mohan, Viswanathan; Avezum, Alvaro; Díaz, Rafael; Rosengren, Annika; Lanas, Fernando; Lopez-Jaramillo, Patricio; Li, Wei; Oguz, Aytekin; Khatib, Rasha; Poirier, Paul; Mohammadifard, Noushin; Pepe, Andrea; Alhabib, Khalid F.; Chifamba, Jephat; Yusufali, Afzal Hussein; Iqbal, Romaina; Yeates, Karen; Yusoff, Khalid; Ismail, Noorhassim; Teo, Koon; Swaminathan, Sumathi; Liu, Xiaoyun; Zatońska, Katarzyna; Yusuf, Rita; Yusuf, Salim; The PURE Study Investigators; MasiraBACKGROUND Most data regarding the association between the glycemic index and cardiovascular disease come from high-income Western populations, with little information from non-Western countries with low or middle incomes. To fill this gap, data are needed from a large, geographically diverse population. METHODS This analysis includes 137,851 participants between the ages of 35 and 70 years living on five continents, with a median follow-up of 9.5 years. We used countryspecific food-frequency questionnaires to determine dietary intake and estimated the glycemic index and glycemic load on the basis of the consumption of seven categories of carbohydrate foods. We calculated hazard ratios using multivariable Cox frailty models. The primary outcome was a composite of a major cardiovascular event (cardiovascular death, nonfatal myocardial infarction, stroke, and heart failure) or death from any cause. RESULTS In the study population, 8780 deaths and 8252 major cardiovascular events occurred during the follow-up period. After performing extensive adjustments comparing the lowest and highest glycemic-index quintiles, we found that a diet with a high glycemic index was associated with an increased risk of a major cardiovascular event or death, both among participants with preexisting cardiovascular disease (hazard ratio, 1.51; 95% confidence interval [CI], 1.25 to 1.82) and among those without such disease (hazard ratio, 1.21; 95% CI, 1.11 to 1.34). Among the components of the primary outcome, a high glycemic index was also associated with an increased risk of death from cardiovascular causes. The results with respect to glycemic load were similar to the findings regarding the glycemic index among the participants with cardiovascular disease at baseline, but the association was not significant among those without preexisting cardiovascular disease. CONCLUSIONS In this study, a diet with a high glycemic index was associated with an increased risk of cardiovascular disease and death.

- PublicaciónAcceso abiertoImpact of social isolation on mortality and morbidity in 20 high-income, middle-income and low-income countries in five continents(BMJ Journals, 2021-03-22) Naito, Ryo; Leong, Darryl P.; Bangdiwala, Shrikant Ishver; McKee, Martin; Subramanian, S. V.; Rangarajan, Sumathy; Islam, Shofiqul; Avezum, Alvaro; Yeates, Karen; Lear, Scott A.; Gupta, Rajeev; Yusufali, Afzalhussein; Dans, Antonio L.; Szuba, Andrzej; Alhabib, Khalid F.; Kaur, Manmeet; Rahman, Omar; Seron, Pamela; Diaz, Rafael; Puoane, Thandi; Liu, Weida; Zhu, Yibing; Sheng, Yundong; Lopez-Jaramillo, Patricio; Chifamba, Jephat; Rosnah, Ismail; Karsidag, Kubilay; Kelishadi, Roya; Rosengren, Annika; Khatib, Rasha; K. R., Leela Itty Amma; Iqbal Azam, Syed; Teo, Koon; Yusuf, Salim; MasiraObjective To examine the association between social isolation and mortality and incident diseases in middle-aged adults in urban and rural communities from high-income, middle-income and low-income countries. Design Population-based prospective observational study. Setting Urban and rural communities in 20 high income, middle income and low income. Participants 119894 community-dwelling middle-aged adults. Main outcome measures Associations of social isolation with mortality, cardiovascular death, non-cardiovascular death and incident diseases. Results Social isolation was more common in middleincome and high-income countries compared with lowincome countries, in urban areas than rural areas, in older individuals and among women, those with less education and the unemployed. It was more frequent among smokers and those with a poorer diet. Social isolation was associated with greater risk of mortality (HR of 1.26, 95% CI: 1.17 to 1.36), incident stroke (HR: 1.23, 95%CI: 1.07 to 1.40), cardiovascular disease (HR: 1.15, 95%CI: 1.05 to 1.25) and pneumonia (HR:1.22, 95%CI: 1.09 to 1.37), but not cancer. The associations between social isolation and mortality were observed in populations in high-income, middle-income and low-income countries (HR (95%CI): 1.69 (1.32 to 2.17), 1.27 (1.15 to 1.40) and 1.47 (1.25 to 1.73), respectively, interaction p=0.02). The HR associated with social isolation was greater in men than women and in younger than older individuals. Mediation analyses for the association between social isolation and mortality showed that unhealthy behaviours and comorbidities may account for about one-fifth of the association. Conclusion Social isolation is associated with increased risk of mortality in countries at different economic levels. The increasing share of older people in populations in many countries argues for targeted strategies to mitigate its adverse effects
- PublicaciónAcceso abiertoThe household economic burden of non-communicable diseases in 18 countries(BMJ Global Health, 2020-02-11) Murphy, Adrianna; Palafox, Benjamin; Walli-Attaei, Marjan; Powell-Jackson, Timothy; Rangarajan, Sumathy; Alhabib, Khalid F.; Avezum, Alvaro; Tumerdem Calik, Kevser Burcu; Chifamba, Jephat; Choudhury, Tarzia; Dagenais, Gilles; Dans, Antonio; Gupta, Rajeev; Iqbal, Romaina; Kaur, Manmeet; Kelishadi, Roya; Khatib, Rasha; Kruger, Iolanthe Marike; Raman Kutty, Vellappillil; Lear, Scott A.; Li, Wei; Lopez-Jaramillo, Patricio; Mohan, Viswanathan; Mony, Prem K.; Orlandin, Andres; Rosengren, Annika; Rosnah, Ismail; Seron, Pamela; Teo, Koon; Tse, Lap Ah; Tsolekile, Lungiswa; Wang, Yang; Wielgosz, Andreas; Yan, Ruohua; Yeates, Karen; Yusoff, Khalid; Zatonska, Katarzyna; Hanson, Kara; Yusuf, Salim; McKee, Martin; EverestAbstract Background Non-communicable diseases (NCDs) are the leading cause of death globally. In 2014, the United Nations committed to reducing premature mortality from NCDs, including by reducing the burden of healthcare costs. Since 2014, the Prospective Urban and Rural Epidemiology (PURE) Study has been collecting health expenditure data from households with NCDs in 18 countries. Methods Using data from the PURE Study, we estimated risk of catastrophic health spending and impoverishment among households with at least one person with NCDs (cardiovascular disease, diabetes, kidney disease, cancer and respiratory diseases; n=17 435), with hypertension only (a leading risk factor for NCDs; n=11 831) or with neither (n=22 654) by country income group: high-income countries (Canada and Sweden), upper middle income countries (UMICs: Brazil, Chile, Malaysia, Poland, South Africa and Turkey), lower middle income countries (LMICs: the Philippines, Colombia, India, Iran and the Occupied Palestinian Territory) and low-income countries (LICs: Bangladesh, Pakistan, Zimbabwe and Tanzania) and China. Results The prevalence of catastrophic spending and impoverishment is highest among households with NCDs in LMICs and China. After adjusting for covariates that might drive health expenditure, the absolute risk of catastrophic spending is higher in households with NCDs compared with no NCDs in LMICs (risk difference=1.71%; 95% CI 0.75 to 2.67), UMICs (0.82%; 95% CI 0.37 to 1.27) and China (7.52%; 95% CI 5.88 to 9.16). A similar pattern is observed in UMICs and China for impoverishment. A high proportion of those with NCDs in LICs, especially women (38.7% compared with 12.6% in men), reported not taking medication due to costs. Conclusions Our findings show that financial protection from healthcare costs for people with NCDs is inadequate, particularly in LMICs and China. While the burden of NCD care may appear greatest in LMICs and China, the burden in LICs may be masked by care foregone due to costs. The high proportion of women reporting foregone care due to cost may in part explain gender inequality in treatment of NCDs.
- PublicaciónAcceso abiertoVariations in common diseases, hospital admissions, and deaths in middle-aged adults in 21 countries from five continents (PURE)(Elsevier Inc., 2019-09-03) Dagenais, Gilles R.; Leong, Darryl P.; Rangarajan, Sumathy; Lanas, Fernando; Lopez-Jaramillo, Patricio; Gupta, Rajeev; Diaz, Rafael; Avezum, Alvaro; Alhabib, Khalid F.; Temizhan, Ahmet; Ismail, Noorhassim; Chifamba, Jephat; Yeates, Karen; Khatib, Rasha; Rahman, Omar; Zatonska, Katarzyna; Kazmi, Khawar; Wei, Li; Zhu, Jun; Rosengren, Annika; Vijayakumar, K.; Kaur, Manmeet; Mohan, Viswanathan; Yusufali, AfzalHussein; Kelishadi, Roya; Teo, Koon K.; Joseph, Philip; Yusuf, Salim; Elsevier; EverestBackground To our knowledge, no previous study has prospectively documented the incidence of common diseases and related mortality in high-income countries (HICs), middle-income countries (MICs), and low-income countries (LICs) with standardised approaches. Such information is key to developing global and context-specific health strategies. In our analysis of the Prospective Urban Rural Epidemiology (PURE) study, we aimed to evaluate differences in the incidence of common diseases, related hospital admissions, and related mortality in a large contemporary cohort of adults from 21 HICs, MICs, and LICs across five continents by use of standardised approaches. Methods The PURE study is a prospective, population-based cohort study of individuals aged 35–70 years who have been enrolled from 21 countries across five continents. The key outcomes were the incidence of fatal and non-fatal cardiovascular diseases, cancers, injuries, respiratory diseases, and hospital admissions, and we calculated the age-standardised and sex-standardised incidence of these events per 1000 person-years. Findings This analysis assesses the incidence of events in 162 534 participants who were enrolled in the first two phases of the PURE core study, between Jan 6, 2005, and Dec 4, 2016, and who were assessed for a median of 9·5 years (IQR 8·5–10·9). During follow-up, 11 307 (7·0%) participants died, 9329 (5·7%) participants had cardiovascular disease, 5151 (3·2%) participants had a cancer, 4386 (2·7%) participants had injuries requiring hospital admission, 2911 (1·8%) participants had pneumonia, and 1830 (1·1%) participants had chronic obstructive pulmonary disease (COPD). Cardiovascular disease occurred more often in LICs (7·1 cases per 1000 person-years) and in MICs (6·8 cases per 1000 person-years) than in HICs (4·3 cases per 1000 person-years). However, incident cancers, injuries, COPD, and pneumonia were most common in HICs and least common in LICs. Overall mortality rates in LICs (13·3 deaths per 1000 person-years) were double those in MICs (6·9 deaths per 1000 person-years) and four times higher than in HICs (3·4 deaths per 1000 person-years). This pattern of the highest mortality in LICs and the lowest in HICs was observed for all causes of death except cancer, where mortality was similar across country income levels. Cardiovascular disease was the most common cause of deaths overall (40%) but accounted for only 23% of deaths in HICs (vs 41% in MICs and 43% in LICs), despite more cardiovascular disease risk factors (as judged by INTERHEART risk scores) in HICs and the fewest such risk factors in LICs. The ratio of deaths from cardiovascular disease to those from cancer was 0·4 in HICs, 1·3 in MICs, and 3·0 in LICs, and four upper-MICs (Argentina, Chile, Turkey, and Poland) showed ratios similar to the HICs. Rates of first hospital admission and cardiovascular disease medication use were lowest in LICs and highest in HICs. Interpretation Among adults aged 35–70 years, cardiovascular disease is the major cause of mortality globally. However, in HICs and some upper-MICs, deaths from cancer are now more common than those from cardiovascular disease, indicating a transition in the predominant causes of deaths in middle-age. As cardiovascular disease decreases in many countries, mortality from cancer will probably become the leading cause of death. The high mortality in poorer countries is not related to risk factors, but it might be related to poorer access to health care.

An analysis of data from 179 000 participants from 63 countries(The Lancet Global Health, 2022-02-24) Sathish, Thirunavukkarasu; Teo, Koon; Britz-McKibbin, Philip; Gill, Biban; Islam, Shofiqul; Pare, Guillaume; Rangarajan, Sumathy; Duong, MyLinh; Lanas, Fernando; Lopez-Jaramillo, Patricio; Mony, Prem; Pinnaka, Lakshmi; Raman Kutty, Vellappillil; Orlandini, Andres; Avezum, Alvaro; Wielgosz, Andreas; Poirier, Paul; Alhabib, Khalid F.; Temizhan, Ahmet; Chifamba, Jephat; Yeates, Karen; Kruger, Iolanthé M.; Khatib, Rasha; Yusuf, Rita; Rosengren, Annika; Zatonska, Katarzyna; Iqbal, Romaina; Lui, Weida; Lang, Xinyue; Li, Sidong; Hu, Bo; Dans, Antonio; Yusufali, Afzalhussein; Bahonar, Ahmad; O’Donnell, Martin J.; McKee, Martin; Yusuf, Salim; MasiraBackground Separate studies suggest that the risks from smoking might vary between high-income (HICs), middle-income (MICs), and low-income (LICs) countries, but this has not yet been systematically examined within a single study using standardised approaches. We examined the variations in risks from smoking across different country income groups and some of their potential reasons. Methods We analysed data from 134 909 participants from 21 countries followed up for a median of 11·3 years in the Prospective Urban Rural Epidemiology (PURE) cohort study; 9711 participants with myocardial infarction and 11 362 controls from 52 countries in the INTERHEART case-control study; and 11 580 participants with stroke and 11 331 controls from 32 countries in the INTERSTROKE case-control study. In PURE, all-cause mortality, major cardiovascular disease, cancers, respiratory diseases, and their composite were the primary outcomes for this analysis. Biochemical verification of urinary total nicotine equivalent was done in a substudy of 1000 participants in PURE. Findings In PURE, the adjusted hazard ratio (HR) for the composite outcome in current smokers (vs never smokers) was higher in HICs (HR 1·87, 95% CI 1·65–2·12) than in MICs (1·41, 1·34–1·49) and LICs (1·35, 1·25–1·46; interaction p<0·0001). Similar patterns were observed for each component of the composite outcome in PURE, myocardial infarction in INTERHEART, and stroke in INTERSTROKE. The median levels of tar, nicotine, and carbon monoxide displayed on the cigarette packs from PURE HICs were higher than those on the packs from MICs. In PURE, the proportion of never smokers reporting high second-hand smoke exposure (≥1 times/day) was 6·3% in HICs, 23·2% in MICs, and 14·0% in LICs. The adjusted geometric mean total nicotine equivalent was higher among current smokers in HICs (47·2 μM) than in MICs (31·1 μM) and LICs (25·2 μM; ANCOVA p<0·0001). By contrast, it was higher among never smokers in LICs (18·8 μM) and MICs (11·3 μM) than in HICs (5·0 μM; ANCOVA p=0·0001). Interpretation The variations in risks from smoking between country income groups are probably related to the higher exposure of tobacco-derived toxicants among smokers in HICs and higher rates of high second-hand smoke exposure among never smokers in MICs and LICs.

However, internationally comparative data regarding the financial impact on individuals is sparse. Therefore, we conducted a survey of the financial impact of the pandemic on individuals, using an international cohort that has been well-characterized prior to the pandemic. Methods Between August 2020 and September 2021, we surveyed 24,506 community-dwelling participants from the Prospective Urban-Rural Epidemiology (PURE) study across high (HIC), upper middle (UMIC)-and lower middle (LMIC)-income countries. We collected information regarding the impact of the pandemic on their self-reported personal finances and sources of income. Findings Overall, 32.4% of participants had suffered an adverse financial impact, defined as job loss, inability to meet financial obligations or essential needs, or using savings to meet financial obligations. 8.4% of participants had lost a job (temporarily or permanently); 14.6% of participants were unable to meet financial obligations or essential needs at the time of the survey and 16.3% were using their savings to meet financial obligations. Participants with a post-secondary education were least likely to be adversely impacted (19.6%), compared with 33.4% of those with secondary education and 33.5% of those with pre-secondary education. Similarly, those in the highest wealth tertile were least likely to be financially impacted (26.7%), compared with 32.5% in the middle tertile and 30.4% in the bottom tertile participants. Compared with HICs, financial impact was greater in UMIC [odds ratio of 2.09 (1.88 −2.33)] and greatest in LMIC [odds ratio of 16.88 (14.69−19.39)]. HIC participants with the lowest educational attainment suffered less financial impact (15.1% of participants affected) than those with the highest education in UMIC (22.0% of participants affected). Similarly, participants with the lowest education in UMIC experienced less financial impact (28.3%) than those with the highest education in LMIC (45.9%). A similar gradient was seen across country income categories when compared by pre-pandemic wealth status. Interpretation The financial impact of the pandemic differs more between HIC, UMIC, and LMIC than between socio-economic categories within a country income level. The most disadvantaged socio-economic subgroups in HIC had a lower financial impact from the pandemic than the most advantaged subgroup in UMIC, with a similar disparity seen between UMIC and LMIC. Continued high levels of infection will exacerbate financial inequity between countries and hinder progress towards the sustainable development goals, emphasising the importance of effective measures to control COVID-19 and, especially, ensuring high vaccine coverage in all countries.

- PublicaciónAcceso abiertoWhite rice intake and incident diabetes: A study of 132,373 participants in 21 countries(Diabetes Care, 2020-09-01) Bhavadharini, Balaji; Mohan, Viswanathan; Dehghan, Mahshid; Rangarajan, Sumathy; Swaminathan, Sumathi; Rosengren, Annika; Wielgosz, Andreas; Avezum, Alvaro; Lopez-Jaramillo, Patricio; Dans, Antonio; Yeates, Karen; Poirier, Paul; Chifamba, Jephat; Alhabib, Khalid F.; Mohammadifard, Noushin; Zatonska, Katarzyna; Khatib, Rasha; Keskinler, Mirac Vural; Wei, Li; Wang, Chuangshi; Liu, Xiaoyun; Iqbal, Romaina; Yusuf, Rita; Wentzel-Viljoen, Edelweiss; Yusufali, Afzalhussein; Diaz, Rafael; Kien Keat, Ng; Lakshmi, P.V.M.; Ismail, Noorhassim; Gupta, Rajeev; Palileo-Villanueva, Lia M.; Sheridan, Patrick; Mente, Andrew; Yusuf, Salim; MasiraOBJECTIVE Previous prospective studies on the association of white rice intake with incident diabetes have shown contradictory results but were conducted in single countries and predominantly in Asia. We report on the association of white rice with risk of diabetes in the multinational Prospective Urban Rural Epidemiology (PURE) study. RESEARCH DESIGN AND METHODS Data on 132,373 individuals aged 35–70 years from 21 countries were analyzed. White rice consumption (cooked) was categorized as <150, ≥150 to <300, ≥300 to <450, and ≥450 g/day, based on one cup of cooked rice = 150 g. The primary outcome was incident diabetes. Hazard ratios (HRs) were calculated using a multivariable Cox frailty model. RESULTS During a mean follow-up period of 9.5 years, 6,129 individuals without baseline diabetes developed incident diabetes. In the overall cohort, higher intake of white rice (≥450 g/day compared with <150 g/day) was associated with increased risk of diabetes (HR 1.20; 95% CI 1.02–1.40; P for trend = 0.003). However, the highest risk was seen in South Asia (HR 1.61; 95% CI 1.13–2.30; P for trend = 0.02), followed by other regions of the world (which included South East Asia, Middle East, South America, North America, Europe, and Africa) (HR 1.41; 95% CI 1.08–1.86; P for trend = 0.01), while in China there was no significant association (HR 1.04; 95% CI 0.77–1.40; P for trend = 0.38). CONCLUSIONS Higher consumption of white rice is associated with an increased risk of incident diabetes with the strongest association being observed in South Asia, while in other regions, a modest, nonsignificant association was seen.
