Dietary patterns are important for the physical and psychological development of adolescents. The purpose of this study is to determine magnitude and severity of depression and its relation with diet diversity score (DDS) among adolescent high school students.
A cross-sectional study was conducted among 546 adolescents selected from schools using multistage sampling technique. Dietary intakes were assessed using a 24-h dietary recall, and depression severity and prevalence were assessed by PHQ-9A. A structured questionnaire was used to collect data. Linear regression analysis was used, and unstandardized beta (ß) coefficients with 95% confidence intervals (CI) were computed to determine the association of depression and its severity with dietary diversity score.
In all, 546 questionnaires were filled completely and consistently making a response rate of 97.3%. The dietary diversity score in 97 (17.8%) of the adolescents were between 1 and 3 (low dietary diversity score) but 259 (47.4%) scored greater than 6 (high dietary diversity score). Chi-square test revealed that with a decrease in DDS from highest to lowest level, the percentage of moderate to severe and severe depression slightly increased (3.4%). In addition, the percentage of moderate to severe and severe depression who consumed meat, fish and milk and dairy products slightly increased (3% and 3.2%). Multivariate adjusted regression analysis demonstrated that dietary diversity score was found to be inversely associated with depression severity and prevalence.
It was found that linear association between diet diversity and depression severity, and prevalence after adjustment for relevant con-founders. The study provided epidemiological evidence of a robust association of dietary pattern with depression symptoms' severity and prevalence in adolescents.
