In Pakistan, the prevalence of stunting among children younger than 5 y has remained above WHO critical thresholds (≥30%) over the past 2 decades. We hypothesized that an unconditional cash transfer (UCT) combined with lipid-based nutrient supplement (LNS) and/or social and behavior change communication (SBCC) will prevent stunting among children 6–23 mo of age. This was a 4-arm, community-based cluster randomized controlled trial conducted in the district of Rahim Yar Khan, Pakistan. A total of 1729 children (UCT, n = 434; UCT + SBCC, n = 433; UCT + LNS, n = 430; and UCT + LNS + SBCC, n = 432) were enrolled at 6 mo of age and measured monthly for 18 mo until the age of 24 mo. At 24 mo of age, children who received UCT + LNS [rate ratio (RR): 0.85; 95% CI: 0.74, 0.97; P = 0.015) and UCT + LNS + SBCC (RR: 0.86; 95% CI: 0.77, 0.96; P = 0.007) had a significantly lower risk of being stunted compared with the UCT arm. No significant difference was noted among children who received UCT + SBCC (RR: 1.03; 95% CI: 0.91, 1.16; P = 0.675) in the risk of being stunted compared with the UCT arm. The pooled prevalence of stunting among children aged 6–23 mo was 41.7%, 44.8%, 38.5%, and 39.3% in UCT, UCT + SBCC, UCT + LNS, and UCT + LNS + SBCC, respectively. In pairwise comparisons, a significant impact on stunting among children in UCT + LNS (P = 0.029) and UCT + LNS + SBCC (P = <0.001) was noted compared with the UCT arm. UCT combined with LNS and UCT + LNS + SBCC were effective in reducing the prevalence of stunting among children aged 6–23 mo in marginalized populations. UCT + SBCC was not effective in reducing the child stunting prevalence. This trial was registered at clinicaltrials.gov as NCT03299218.
