Study: Added Sugars In Diet Lowers Sleep Quality For Women, Increasing Heart Disease Risks (AHA)

Journal of the American Heart Association study (Feb 17, 2020):

American Heart Association AHA logoThe association between poor overall sleep quality and greater consumption of added sugars observed in the current study aligns with previous findings that intakes of confectionary and sugar‐sweetened beverages were higher in middle‐aged Japanese women reporting poor, compared with good, sleep quality.

Background – Poor sleep increases cardiovascular disease risk, and diet likely contributes to this relationship. However, there are limited epidemiological data on the relationship between measures of sleep quality and habitual dietary patterns. This study examined these associations in a diverse sample of women.

Both short sleep duration and poor sleep quality are associated with the development of obesity, type 2 diabetes mellitus, and cardiovascular disease (CVD), and it is likely that the relationship between sleep and cardiometabolic disease risk is partially mediated by diet.5 Indeed, experimental studies demonstrate that restricting sleep duration leads to increases in energy intake, confirming associations of short sleep with higher energy intakes in observational population‐based studies.
