Abstract Objective: This study aimed to identify individual and contextual factors that are associated with under- and over-nutrition among school-aged children and adolescents in two Nigerian states. Design: Community-based cross-sectional study. Setting: The study was carried out in rural and urban communities of Osun and Gombe States in Nigeria. Participants: A total of 1200 school-aged children and adolescents. Results: Multi-level analysis showed that the full models accounted for about 82 % and 39 % of the odds of thinness or overweight/obese across the communities, respectively. Household size (adjusted OR (aOR) 1·10; P = 0·001; 95 % CI (1·04, 1·16)) increased the odds, while the upper wealth index (aOR 0·43; P = 0·016; 95 % CI (0·22, 0·86)) decreased the odds of thinness. Age (aOR 0·86; P < 0·001; 95 % CI (1·26, 8·70)), exclusive breastfeeding (aOR 0·46; P = 0·010; 95 % CI (0·25, 0·83)), physical activity (aOR 0·55; P = 0·001; 95 % CI (0·39, 0·78)) and the upper wealth index (aOR 0·47; P = 0·018; 95 % CI (0·25, 0·88)) were inversely related with overweight/obesity, while residing in Osun State (aOR 3·32; P = 0·015; 95 % CI (1·26, 1·70)), female gender (aOR 1·73; P = 0·015; 95 % CI (1·11, 2·69)) and screen time > 2 h/d (aOR 2·33; P = 0·005; 95 % CI (1·29, 4·19)) were positively associated with overweight/obesity. Conclusions: The study shows that selected community and individual-level factors are strongly associated with thinness and overweight/obesity among school-aged children and adolescents.
