- 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 estimated sleep duration and naps with mortality and cardiovascular events(European Society of Cardiology, 2019-05-21) Wang, Chuangshi; Bangdiwala, Shrikant I.; Rangarajan, Sumathy; Lear, Scott A.; AlHabib, Khalid F.; Mohan, Viswanathan; Koon, Teo; Poirier, Paul; Tse, Lap Ah; Liu, Zhiguang; Rosengren, Annika; Kumar, Rajesh; Lopez-Jaramillo, Patricio; Yusoff, Khalid; Monsef, Nahed; Krishnapillai, Vijayakumar; Ismail, Noorhassim; Seron, Pamela; Dans, Antonio; Kruger, Lanthé; Yeates, Karen; Leach, Lloyd; Yusuf, Rita; Orlandini, Andres; Wolyniec, Maria; Bahonar, Ahmad; Mohan, Indu; Khatib, Rasha; Temizhan, Ahmet; Li, Wei; Yusuf, Salim; On behalf of the Prospective Urban Rural Epidemiology (PURE) study investigators; EverestAims To investigate the association of estimated total daily sleep duration and daytime nap duration with deaths and major cardiovascular events. Methods and results We estimated the durations of total daily sleep and daytime naps based on the amount of time in bed and self-reported napping time and examined the associations between them and the composite outcome of deaths and major cardiovascular events in 116 632 participants from seven regions. After a median follow-up of 7.8 years, we recorded 4381 deaths and 4365 major cardiovascular events. It showed both shorter (≤6 h/day) and longer (>8 h/day) estimated total sleep durations were associated with an increased risk of the composite outcome when adjusted for age and sex. After adjustment for demographic characteristics, lifestyle behaviours and health status, a J-shaped association was observed. Compared with sleeping 6–8 h/day, those who slept ≤6 h/day had a non-significant trend for increased risk of the composite outcome [hazard ratio (HR), 1.09; 95% confidence interval, 0.99–1.20]. As estimated sleep duration increased, we also noticed a significant trend for a greater risk of the composite outcome [HR of 1.05 (0.99–1.12), 1.17 (1.09–1.25), and 1.41 (1.30–1.53) for 8–9 h/day, 9–10 h/day, and >10 h/day, Ptrend < 0.0001, respectively]. The results were similar for each of all-cause mortality and major cardiovascular events. Daytime nap duration was associated with an increased risk of the composite events in those with over 6 h of nocturnal sleep duration, but not in shorter nocturnal sleepers (≤6 h). Conclusion Estimated total sleep duration of 6–8 h per day is associated with the lowest risk of deaths and major cardiovascular events. Daytime napping is associated with increased risks of major cardiovascular events and deaths in those with >6 h of nighttime sleep but not in those sleeping ≤6 h/night.

- PublicaciónAcceso abiertoTiming and Length of Nocturnal Sleep and Daytime Napping and Associations with Obesity Types in High-, Middle-, and Low-Income Countries(JAMA, 2021-06-30) Tse, Lap Ah; Wang, Chuangshi; Rangarajan, Sumathy; Liu, Zhiguang; Teo, Koon; Yusufali, Afzalhussein; Avezum, Alvaro; Wielgosz, Andreas; Rosengren, Annika; Kruger, Iolanthé M.; Chifamba, Jephat; Tumerdem Calik, Kevser Burcu; Tumerdem Calik, Kevser Burcu; Zatońska, Katarzyna; AlHabib, Khalid F.; Yusoff, Khalid; Kaur, Manmeet; Ismail, Noorhassim; Seron, Pamela; Lopez-Jaramillo, Patricio; Poirier, Paul; Gupta, Rajeev; Khatib, Rasha; Kelishadi, Roya; Lear, Scott A.; Choudhury, Tarzia; Mohan, Viswanathan; Li, Wei; Yusuf, Salim; MasiraImportance Obesity is a growing public health threat leading to serious health consequences. Late bedtime and sleep loss are common in modern society, but their associations with specific obesity types are not well characterized. Objective To assess whether sleep timing and napping behavior are associated with increased obesity, independent of nocturnal sleep length. Design, Setting, and Participants This large, multinational, population-based cross-sectional study used data of participants from 60 study centers in 26 countries with varying income levels as part of the Prospective Urban Rural Epidemiology study. Participants were aged 35 to 70 years and were mainly recruited during 2005 and 2009. Data analysis occurred from October 2020 through March 2021. Exposures Sleep timing (ie, bedtime and wake-up time), nocturnal sleep duration, daytime napping. Main Outcomes and Measures The primary outcomes were prevalence of obesity, specified as general obesity, defined as body mass index (BMI; calculated as weight in kilograms divided by height in meters squared) of 30 or greater, and abdominal obesity, defined as waist circumference greater than 102 cm for men or greater than 88 cm for women. Multilevel logistic regression models with random effects for study centers were performed to calculate adjusted odds ratios (AORs) and 95% CIs. Results Overall, 136 652 participants (81 652 [59.8%] women; mean [SD] age, 51.0 [9.8] years) were included in analysis. A total of 27 195 participants (19.9%) had general obesity, and 37 024 participants (27.1%) had abdominal obesity. The mean (SD) nocturnal sleep duration was 7.8 (1.4) hours, and the median (interquartile range) midsleep time was 2:15 am (1:30 am-3:00 am). A total of 19 660 participants (14.4%) had late bedtime behavior (ie, midnight or later). Compared with bedtime between 8 pm and 10 pm, late bedtime was associated with general obesity (AOR, 1.20; 95% CI, 1.12-1.29) and abdominal obesity (AOR, 1.20; 95% CI, 1.12-1.28), particularly among participants who went to bed between 2 am and 6 am (general obesity: AOR, 1.35; 95% CI, 1.18-1.54; abdominal obesity: AOR, 1.38; 95% CI, 1.21-1.58). Short nocturnal sleep of less than 6 hours was associated with general obesity (eg, <5 hours: AOR, 1.27; 95% CI, 1.13-1.43), but longer napping was associated with higher abdominal obesity prevalence (eg, ≥1 hours: AOR, 1.39; 95% CI, 1.31-1.47). Neither going to bed during the day (ie, before 8pm) nor wake-up time was associated with obesity. Conclusions and Relevance This cross-sectional study found that late nocturnal bedtime and short nocturnal sleep were associated with increased risk of obesity prevalence, while longer daytime napping did not reduce the risk but was associated with higher risk of abdominal obesity. Strategic weight control programs should also encourage earlier bedtime and avoid short nocturnal sleep to mitigate obesity epidemic.
- 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.
