Children with severe underweight were significantly less probable to perform well in SBJ (OR= 0.96, CI= 0.94; 0.99) and 20-meter shuttle run (OR= 1.39, CI= 1.22; 1.61). Childhood overweight was associated with increased SBP (OR= 1.03, CI= 1.02; 1.05) and poor SBJ (OR= 0.98, CI= 0.97; 0.99). Obese children were significantly associated with increased SBP (OR= 1.04, CI= 1.02; 1.06), poor SR (OR= 0.92, CI= 0.87; 0.98) and SBJ (OR= 0.94, CI= 0.93; 0.96) scores compared to age- and sex-specific norms.<br> <strong>Conclusion. </strong>Elevated BP and poor musculoskeletal fitness could adversely affect the well-being of undernourished, overweight, and obese Nigerian children. Findings implicate the need to implement dietary and physical activity intervention programs to promote desirable health-related quality of life in school-going children.</div> Triponderal Mass Index, Musculoskeletal Fitness, Children, Sub-Saharan Africa 0 0 http://aassjournal.com/browse.php?a_code=A-11-1800-2&slc_lang=en&sid=1 Sunday Onagbiye 24539678@nwu.ac.za 100319475328460011288 100319475328460011288 Yes The Africa Unit for Transdisciplinary Health Research (AUTHeR), North-West University, Potchefstroom Campus, South Africa Olumatoyin Toriola ptoriola@psu.edu.sa 100319475328460011289 100319475328460011289 No Prince Sultan University, Women Campus, Health and Physical Education Department, Riyadh, Kingdom of Saudi Arabia
