The effect of increased coverage of participatory women's groups on neonatal mortality in Bangladesh: A cluster randomized trial.
IMPORTANCE Community-based interventions can reduce  neonatal mortality  when health systems are weak . Population coverage of target groups may be an important determinant of their effect on behavior and mortality . A women 's group trial at coverage of 1 group per 1414 population in rural Bangladesh showed no effect on neonatal mortality , despite a similar intervention having a significant effect on neonatal and maternal death in comparable setting s. OBJECTIVE To assess the effect of a participatory women 's group intervention with higher population coverage on  neonatal mortality  in Bangladesh . DESIGN A cluster r and omized controlled trial in 9 intervention and 9 control clusters . SETTING Rural Bangladesh . PARTICIPANTS Women permanently residing in 18 unions in 3 districts and accounting for 19 301 births during the final 24 months of the intervention .  INTERVENTIONS Women 's groups at a coverage of 1 per 309 population that proceed through a participatory learning and action cycle in which they prioritize issues that affected maternal and neonatal health and design and implement strategies to address these issues . MAIN OUTCOMES AND MEASURES Neonatal mortality rate . RESULTS Analysis included 19 301 births during the final 24 months of the intervention . More than one-third of newly pregnant women joined the groups . The neonatal mortality rate was significantly lower in the intervention arm ( 21.3 neonatal deaths per 1000 live births vs 30.1 per 1000 in control areas ) , a reduction in neonatal mortality of 38 % ( risk ratio , 0.62 [ 95 % CI , 0.43 - 0.89 ] ) when adjusted for socioeconomic factors . The cost-effectiveness was US $ 220 to $ 393 per year of life lost averted . Cause-specific mortality rates suggest reduced deaths due to infections and those associated with prematurity/low birth weight . Improvements were seen in hygienic home delivery practice s , newborn thermal care , and breastfeeding practice s. CONCLUSIONS AND RELEVANCE Women 's group community mobilization , delivered at adequate population coverage , is a highly cost-effective approach to improve newborn survival and health behavior indicators in rural Bangladesh .
