Women who sleep poorly tend to overeat and consume a lower-quality diet, according to a new study from researchers at Columbia University Irving Medical Center. The findings provide new insight into how poor sleep quality can increase the risk of heart disease and obesity and points to possible interventions for improving women’s heart health.
Previous studies have shown that people who get less sleep are more likely to develop obesity, type 2 diabetes, and heart disease—and that the relationship may be partially explained by diet. But these studies were narrowly focused on specific foods or nutrients (like fish, sweets, or saturated fat) or only measured sleep duration, not sleep quality.
The new study was designed to get a more comprehensive picture in women by examining associations between overall diet quality and multiple aspects of sleep quality.
