From: Height-obesity relationship in school children in Sub-Saharan Africa: results of a cross-sectional study in Cameroon

Quartiles of height SDS N Mean height (cm) (95% CI) Mean height SDS (95% CI) Mean BMI SDS (95% CI) Prevalence of overweight/obesity

  1. CI, confidence interval; SDS, standard deviation score. Prevalence was estimated using the WHO 2007 BMI cut-off.
  2. *p < 0.05 after One-way ANOVA with post-hoc Bonferroni test.
