Factors associated with dietary diversity among adolescents in Woldia, Northeast Ethiopia

Abstract

Abstract Background Consuming diversified food during the adolescent period is essential to build a healthy and active mind for their later life. Food prices increased in the local market due to fewer production of crops. Thus, exploring the dietary diversity of adolescents in this area is crucial to estimate diet quality. So the aim of the study was to identify determinant factors of dietary diversity. Methods An institution-based cross-sectional study was conducted among adolescent students in Woldia town. A total of four hundred eleven students were included in the study. A simple random sampling technique was used to select the participants. The outcome variable was dietary diversity; it was calculated by summing of the number of food group consumed by individuals in the given reference period. Bivariable and multivariable logistic analysis was done. The odds ratio with a 95% confidence interval was computed to measure an association. A variable with a P-value less than 0.05 is considered a significant factor. Results The proportion of inadequate dietary diversity was 49.1% (95% CI 44.5–53.8). Being female (AOR =5.53, 95% CI 3.447–8.859), secondary and above mothers’ education level (AOR=0. 27, 95%CI 0.153–0.477), living in a family size five and above (AOR= 2.09, 95CI% 1.31–3.34), and poor knowledge about nutrition (AOR=4.56, 95% CI 2.727–7.639) were significantly associated with inadequate dietary diversity. Conclusions and recommendations Inadequate dietary diversity was associated with sex, knowledge of nutrition, maternal education level, and family size. It is better to design a nutrition intervention program that focus on nutrition education to scale up diversified food consumption among adolescents.
