Socioeconomic and gender differences in adolescents' nutritional status in urban Cameroon, Africa

The aim of this study was to assess adolescents' nutritional status according to socioeconomic status (SES) and sex using anthropometry in urban Cameroon, Africa. Adolescent boys (n = 248) and girls (n = 333) 12 to 16 years old were recruited from randomly selected schools in a cross sectional study in Yaoundé city and grouped according to SES. Weight, height, skinfold thickness, and circumferences were measured, and body mass index, waist/hip ratio, arm muscle, and arm fat areas were calculated. Stunting, underweight, and overweight were determined using international cutoff points. Adolescents with medium and high SES were less likely to be stunted than adolescents with low SES (odds ratio [OR], 0.40; P < .01). Prevalences of stunting (12%, 6%, and 5%) and underweight (3%, 4%, and 1%) were higher among the adolescents with low and medium SES than those with high SES. Overweight prevalence was high among the adolescents with low (8%), medium (11%), and high (9%) SES. The OR for overweight was higher among girls than boys (OR, 4.13; P < .001). Girls were less likely to be stunted and underweight than boys (OR, 0.29 [P < .001] and OR, 0.20 [P < .01], respectively). Prevalences of stunting (15% and 6%) and underweight (5% and 2%) were higher among boys than girls. Pubescent adolescents were less likely to be stunted than nonpubescent (OR, 0.53; P < .05). Adolescents with low and medium SES were more underweight and stunted than adolescents with high SES. Girls were more overweight, less stunted, and underweight than boys.
