Prevalence and correlates of underweight among lactating mothers aged 20-49 years living in the Urban Slums of Kampala City, Uganda: A mixed-methods cross-sectional study.

Suboptimal nutrient intake during lactation contributes to maternal underweight and reduced breastmilk quantity and quality, with potentially severe consequences for maternal and infant health. Although underweight prevalence among lactating mothers in urban slums is presumed higher compared to other areas, empirical data from Kampala's slums remains limited. This study examined the prevalence and correlates of underweight among lactating mothers aged 20-49 years in Kampala's slums. A convergent mixed methods cross-sectional study was conducted among 285 lactating mothers in Kampala's slums. Multivariable modified Poisson regression generated adjusted prevalence ratios (aPRs), with statistical significance at p
