Unhealthy diet has been indicated as a risk factor of depressive emotions. Furthermore, depressive emotions have also been designated as a related factor of eating patterns. However, there still lacks an empirical evidence to show a reciprocal relationship between unhealthy eating and depressive emotions, especially in the childhood. The data came from a longitudinal project followed 2756 children since their 2nd grade (2002) until 11th grade (2011). Hierarchical linear growth curve models conducted by MLwiN 2.27 were used to analyze the longitudinal associations between unhealthy eating and depressive emotions. The frequency of unhealthy eating during the previous year and its difference with the successive year were used to predict the depressive emotions in the successive year, and vice versa. Baseline factors (including Child sex, parent’s marriage status, parent’s educational level, family monthly income, and family activities) and time-varying covariates (including body weight, vegetable or fruit consumption, exercising and smoking) were controlled. The results indicated that depressive emotions and unhealthy eating behaviors increased slightly over time. After controlling the baseline factors and time-varying covariates, the frequency of unhealthy eating during the previous year and its difference with the successive year were positively associated with the initiation and the growth rate of the depressive emotions. Furthermore, the level of depressive emotions in the previous year and its difference with the successive year were positively associated with the initial state and the growth rate of unhealthy eating behavior as well. The results extended our knowledge of the vicious circle between depressive emotions and unhealthy eating behaviors, and contribute to the development of mental health promotion and nutrition education program for preventing children and adolescent depression and unhealthy eating habits.
