Dietary diversity and social determinants of nutrition among late adolescent girls in rural Pakistan

The conditions in which adolescent girls mature shape their health, development and nutrition. Nutrient requirements increase to support growth during adolescence, but gaps between consumption and requirements exist in low‐ and middle‐income countries. We aimed to identify and quantify the relationship between dietary intake and diverse social determinants of nutrition (SDN) among a subset of adolescent girls 15–18.9 years (n = 390) enrolled within the Matiari emPowerment and Preconception Supplementation (MaPPS) Trial. The primary outcome, dietary diversity score (DDS), was derived by applying the Minimum Dietary Diversity for Women 10‐item scale to 24‐h dietary recall data collected three times per participant. To examine the associations between the SDN‐related explanatory variables and DDS, we generated a hierarchical, causal model using mixed effects linear regression to account for the cluster‐randomized trial design. Using all data, diets lacked diversity (DDS mean ± SD: 3.35 ± 1.03 [range: 1–7; n = 1170]), and the minimum cut‐off for dietary diversity was infrequently achieved (13.5%; 95% CI: 11.6–15.6%). Consumption of starches was reported in all recalls, but micronutrient‐rich food consumption was less common. Of the SDN considered, wealth quintile had the strongest association with DDS (P
