Determinants of wasting among schoolchildren in a Southwestern state of Nigeria: Implications to strengthen the nutritional component of primary health-care model

BACKGROUND: Wasting is linked to about one-third of mortality among school-age children. More studies have centered on stunting among under-five children, with few documented studies exploring comparability and determinants of wasting among school pupils in southwestern Nigeria. This study aimed to investigate the comparability and determinants of wasting among schoolchildren in rural and urban communities of Obafemi-Owode local government area, Ogun State, Nigeria. METHODS: A cross-sectional study utilizing a quantitative approach was carried out among children both in rural and urban primary schools. Data were collected through interviewer-administered questionnaires. EPI-INFO version 6.03 was used, children were classified as wasted if weight-for-height Z-scores were <2 standard deviations below the National Center for Health Statistics/World Health Organization median. Associations were tested using t-tests and Chi-square test, while predictors were examined with logistic regression at 95% level of significance. RESULTS: Male gender was predominant (54.6%). Significantly more pupils from rural areas lived with grandparents and other guardians (60.3%) compared to their urban counterparts (39.7% P = 0.005). Pupils from rural schools were four times more likely to be wasted compared to those located in urban regions (odds ratio [OR]: 4.2; 95 confidence interval [CI] = 2.24–7.69). Male pupils were twice likely to be wasted compared to the female pupils (OR: 2.08; 95 CI = 1.22–3.55). CONCLUSION: Conclusively, the study revealed that the prevalence of wasting was higher among children from rural schools than in urban schools. There is an urgent need to implement viable interventions and policies that address nutritional deficiencies in primary school pupils, particularly in rural areas.
