Dietary patterns with fresh fruits and vegetables consumption and quality of sleep among older adults in mainland China

摘要

With modern society's increased pressures, problems arise regarding duration and quality of sleep. Many Chinese seniors report poor quality of sleep. With rapid urbanization, Chinese dietary patterns have shifted dramatically, with vegetables consumption declining rapidly. This research focuses on the associations between fruits and vegetables consumption with basic dietary behaviors and sleeping patterns. Using the 2014 wave of the Chinese Longitudinal Healthy Longevity Survey (CLHLS), multinomial logistic regression models predicted older adults' (age = 65) quality and duration of sleep. Predictors included fruits and vegetables consumption, types of cooking oil, staple foods, and meat. The mean age of the study sample was around 85 years. Approximately 56% of respondents consumed fresh vegetables daily. A majority of seniors consumed rice as their staple food. Only 14% of seniors consumed fresh fruits daily. Most seniors consumed meat weekly or more frequently. We found that seniors who consumed fruits and vegetables occasionally had lower odds of reporting good quality of sleep [ Fruits: AOR (Adjusted odds ratio) = 0.77; Vegetables: AOR = 0.58] compared with daily consumers. Respondents who reported consuming wheat and half rice-half wheat had higher odds of reporting good quality of sleep (Wheat: AOR = 1.52; Half rice-half wheat: AOR = 1.28), compared with seniors who reported rice as their staple food. Chinese public health practitioners and nutritionists should design dietary plans with more frequent consumption of fruits, vegetables, and wheat to help older adults' overall health including their sleeping patterns.
