Perceived stress, depression and food consumption frequency in the college students of China seven cities

Abstract

The aim of the study was to explore the association between perceived stress, depression and food consumption frequency. A self-administered questionnaire that included the perceived stress scale, the depression scale and dietary intake was used in the baseline survey of a cohort study of 2579 local college students over 7 cities in China. Gender and city differences were found in perceived stress scores and depression scores. There were also significant differences among diverse smoking levels and among perceived weight categories in perceived stress and depression scores. Stepwise logistic regression models found that frequency of consumption of fresh fruit, ready-to-eat food and snack food had apparently independent effects on perceived stress, whereas the intake level of fresh fruit, ready-to-eat food and fast food was significantly associated with depression. The link between food consumption frequency, perceived stress and depression suggests that diet intervention may be considered a mediate strategy integrated in psychology prevention program among normal population of the college.
