Health equity impact of community-initiated kangaroo mother care: A randomized controlled trial
Abstract BackgroundKangaroo mother care (KMC) can substantially enhance overall survival of low birthweight babies. In a large randomized controlled trial, we recently showed that supporting mothers to provide community initiated KMC (ciKMC) can reduce early infant mortality by 25% (hazard ratio (HR) 0.75). With the current analysis we aimed to explore if ciKMC promotion leads to increased inequity in survival.MethodsIn the trial we randomised 8402 low birthweight babies to a ciKMC (4480 babies) and a control (3922 babies) arm, between 2015 and 2018 in Haryana, India. The main outcome of interest was the difference in concentration indices between babies in the ciKMC and control arms for survival until 180 days of life.ResultsOur intervention did not increase survival inequity, as reflected in a reduction of the concentration index by 0.05 (95% CI -0.07 to 0.17). Survival impact tended to be higher among those born to illiterate mothers (HR 0.65, 95% CI 0.47 to 0.89), and those in poor families (HR 0.69, 95% CI 0.51 to 0.93).ConclusionsWe found that ciKMC promotion did not increase inequity in survival associated with wealth. The beneficial impact of ciKMC tended to be larger among vulnerable groups. Supporting mothers to provide KMC at home to low birthweight babies will not increase and could indeed reduce inequities in infant survival.Trial registrationClinicalTrials.gov, NCT02653534.
