Abstract
Background: With the rise of the triple burden of malnutrition, the changing nutrition situation in Sub-Saharan Africa may be associated with changes in pubertal timing of adolescents. The purpose of this review was to summarize the association between nutritional status and pubertal milestones among children in SSA.
Method: A search of publications was conducted in PubMed and Scopus on 1st April 2023. Observational studies with children aged 0 to 22 years, that reported nutritional status and association with pubertal milestones in SSA were selected for review. Risk of bias was assessed using the NOS and results were presented using the PRISMA.
Results: Twenty-three studies published from 1992 to 2021 reporting data from nine countries and a total of 21,853 children were included in this review. Mean menarche age relative to nutritional status varied from 17.2 years in stunted adolescents in Senegal to 13.3 (in the underweight), 13.9 (in normal weight girls), and 14.1 (in overweight girls) years in adolescents in Ethiopia. Adolescents who were not stunted in Kenya and those with higher height-for-age z-scores (HAZ) and body mass index (BMI) in South Africa had more advanced breast development. Pubic hair development was positively associated with HAZ and BMI z-scores (BMIZ) at 5 years in South Africa and overweight and obesity in adolescents in Nigeria. Attainment of voice break in adolescent boys in Nigeria was associated with lower likelihood of stunting and underweight. In a study in Zambia, earlier onset and more rapid progression of genital development assessed by testicular volume in boys was associated with increased height and arm muscle.
Conclusions: Higher BMI, height, weight, and triceps skinfolds are significantly associated with advanced pubertal development in SSA. In SSA, less than one-third of the countries have published any research studies on nutritional status and pubertal milestones. Future studies should focus on detailed assessment of pubertal development and associated nutritional factors in both male and female adolescents in SSA.
