The following graphs below show the prevalence of stunting by severity with 95% CIs of severely stunted, moderately stunted, mildly stunted and not stunted among children under 5 years in the Gicumbi (Rwanda) Kitgum (Uganda) and Kilindi (Tanzania) districts. [Agho et al., BMC paediatrics. 2019;19(1):1-1]. Figure 1: Prevalence and 95% confidence intervals (CIs) of stunting by severity a. What explanation can you offer for these differences in stunting prevalence in three disadvantaged East African communities? (4 marks) b. What public health measures would you recommend to these three disadvantaged East African communities to reduce their stunting prevalence by a third by 2030? (3 marks).
