Descriptive change in mean weight per group.

High malnutrition among children with CP in low-income countries underscores the need for community-based nutrition strategies. This study aimed to describe the effectiveness of two caregiver-led interventions including, the positive deviance (PD) and the parent facilitator training (PFT) interventions on malnutrition among children and youth (C&Y) with CP in rural Eastern Uganda. This was a 2x2 factorial quasi-randomized trial among 124 pairs of caregiver-malnourished C&Y with CP aged 2–24 years, at the Iganga Mayuge Health and Demographic Surveillance Site (IMHDSS) in Eastern Uganda. Outcome measures included three months change in weight gain, Weight for-age-z scores and Body Mass Index for-age-z scores. Change in weight status was modelled in a multiple linear regression adjusting for baseline characteristics. Non-factorial analysis was used to determine the effect of combining both interventions on weight status. The interaction effect between PD and PFT was not statistically significant (P > 0.05). Those who received the PD intervention significantly gained more weight by 520g (adjusted coefficient = 0.52, 95%CI 0.16,0.88, p = 0.005) and improved their BMI for age z-scores (adjusted coefficient = 0.65, 95% CI 0.35,0.94, P
