Supper Timing and Cardiovascular Mortality: The Japan Collaborative Cohort Study.

ABSTRACT: Evidence on the role of supper timing in the development of cardiovascular disease (CVD) is limited. In this study, we examined the associations between supper timing and risks of mortality from stroke, coronary heart disease (CHD), and total CVD. A total of 28,625 males and 43,213 females, aged 40 to 79 years, free from CVD and cancers at baseline were involved in this study. Participants were divided into three groups: the early supper group (before 8:00 p.m.), the irregular supper group (time irregular), and the late supper group (after 8:00 p.m.). Cox proportional hazards regression models were used to calculate hazard ratios (HRs) for stroke, CHD, and total CVD according to the supper time groups. During the 19-year follow-up, we identified 4706 deaths from total CVD. Compared with the early supper group, the multivariable HR of hemorrhagic stroke mortality for the irregular supper group was 1.44 (95% confidence interval [CI]: 1.05-1.97). There was no significant association between supper timing and the risk of mortality from other types of stroke, CHD, and CVD. We found that adopting an irregular supper timing compared with having dinner before 8:00 p.m. was associated with an increased risk of hemorrhagic stroke mortality.

Project description:BackgroundWhile women's parity status and education level have independent associations with cardiovascular and other diseases, no studies have evaluated the additive interaction of these two factors. Therefore, we examined the additive interaction between parity and education level on mortality from stroke, coronary heart disease, total cardiovascular disease, cancer, non-cardiovascular disease, and non-cancer causes, and all causes in Japanese women.MethodsThis study followed 41,242 women aged 40-79 years without a history of cardiovascular disease or cancer from 1988 to 1990 until 2009. Baseline parity and education level were classified into four categories, with highly educated parous women as the reference group. Cox proportional hazards regression analyses were performed to calculate the risk of mortality. We also assessed the additive interactions between parity and education level on mortality from cardiovascular disease and other causes using the relative excess risk due to interaction obtained using Cox models.ResultsDuring the median follow-up period of 19.1 years, we identified 6299 deaths. In a multivariable model adjusted for cardiovascular disease and other disease risk factors, nulliparous women with low education levels had increased multivariable-adjusted hazard ratios of 1.67 (95% confidence interval [CI] 1.13, 2.47) for stroke, 1.98 (95% CI 1.15, 3.39) for coronary heart disease, 1.71 (95% CI 1.34,2.18) for total cardiovascular disease, 1.69 (95% CI 1.33, 2.14) for non-cardiovascular and non-cancer, and 1.51 (95% CI 1.30, 1.75) for all-cause mortality when compared with highly educated parous women. Moreover, we observed significant additive interactions between parity and education level on total cardiovascular disease mortality (P = 0.04), non-cardiovascular disease and non-cancer mortality (P = 0.01), and all-cause mortality (P = 0.005).ConclusionsNulliparity and low education levels are super-additively associated with total cardiovascular disease, non-cardiovascular and non-cancer, and all-cause mortality risks, suggesting that nulliparous women with low education levels need specific support for preventing mortality related to cardiovascular and other diseases.

Project description:BackgroundPlanetary and human health are highly intertwined; our current food system is associated with high greenhouse gas emissions (GHGE) and burden of disease.ObjectiveThe aim of this study was to investigate the associations of diet-related GHGE with all-cause and cause-specific mortality in Japan.MethodsThis study included 58,031 Japanese adults (35,078 women and 22,953 men) 40-79 y of age who participated in the Japan Collaborative Cohort Study during the period 1988-1990. Diet-related GHGE was calculated from dietary intake estimated by a validated food frequency questionnaire and previously developed GHGE tables of each food and beverage. Participants were classified into quintiles of diet-related GHGE per kg food/d. Hazard ratios (HRs) of all-cause and cause-specific mortality were calculated using the Cox proportional hazard and restricted cubic spline models.ResultsThe average diet-related GHGE was 1,522 g-CO2-eq/kg food/d. Over a period of 19.3 y (955,819 person-years) of median follow-up, 11,508 deaths were documented. After adjusting for lifestyle and medical history, in comparison with the fourth quintiles of diet-related GHGE, the first and fifth quintiles were associated with a higher risk of all-cause mortality: multivariable HR of all-cause mortality was 1.11 [95% confidence interval (CI): 1.05, 1.18] and 1.09 (95% CI: 1.03, 1.17) for the lowest and highest GHGE, respectively; those of cardiovascular disease mortality were 1.23 (95% CI: 1.10, 1.38) and 1.22 (95% CI: 1.08, 1.37), respectively. The diet-related GHGE range with the lowest HR of all-cause mortality was 1,400-1,600 g-CO2eq/kg food/d (p for nonlinearity <0.001). Replacing one serving of red meat with one serving of pulses was inversely associated with all-cause mortality (HR=0.96; 95% CI: 0.93, 0.99) and GHGE (mean change, -347 g-CO2-eq/kg/d; 95% CI: -353, -342).DiscussionDiet-related GHGE was associated with all-cause and cardiovascular disease mortality in a U-shaped fashion. This finding could be useful for creating a policy for sustainable shifts in dietary habits that will benefit the population and environmental health. https://doi.org/10.1289/EHP14935.
