    Input: David Osrin and colleagues report findings from a cluster-r and omized trial conducted in Mumbai slums ; the trial aim ed to evaluate whether  facilitator-supported women 's groups  could improve perinatal outcomes Background To evaluate a delivery strategy for newborn interventions in rural Bangladesh . Methods A cluster-r and omized controlled trial was conducted in Mirzapur , Bangladesh . Twelve unions were r and omized to intervention or comparison arm . All women of reproductive age were eligible to participate . In the intervention arm , community health workers identified pregnant women ; made two antenatal home visits to promote birth and newborn care preparedness ; made four postnatal home visits to negotiate preventive care practice s and to assess newborns for illness ; and referred sick neonates to a hospital and facilitated compliance . Primary outcome measures were antenatal and immediate newborn care behaviours , knowledge of danger signs , care seeking for neonatal complications , and neonatal mortality . Findings A total of 4616 and 5241 live births were recorded from 9987 and 11153 participants in the intervention and comparison arm , respectively . High coverage of antenatal ( 91 % visited twice ) and postnatal ( 69 % visited on days 0 or 1 ) home visitations was achieved . Indicators of care practice s and knowledge of maternal and neonatal danger signs improved . Adjusted mortality hazard ratio in the intervention arm , compared to the comparison arm , was 1.02 ( 95 % CI : 0.80–1.30 ) at baseline and 0.87 ( 95 % CI : 0.68–1.12 ) at endline . Primary causes of death were birth asphyxia ( 49 % ) and prematurity ( 26 % ) . No adverse events associated with interventions were reported . Conclusion Lack of evidence for mortality impact despite high program coverage and quality assurance of implementation , and improvements in targeted newborn care practice s suggests the intervention did not adequately address risk factors for mortality . The level and cause-structure of neonatal mortality in the local population must be considered in developing interventions . Programs must ensure skilled care during childbirth , including management of birth asphyxia and prematurity , and curative postnatal care during the first two days of life , in addition to essential newborn care and infection prevention and management . Trial Registration Clinical trials.gov Background Maternal , perinatal and neonatal mortality remains high in low-income countries . We evaluated community and facility-based interventions to reduce deaths in three districts of Malawi . Methods We evaluated a rural participatory women ’s group community intervention ( CI ) and a quality improvement intervention at health centres ( FI ) via a two-by-two factorial cluster r and omized controlled trial . Consenting pregnant women were followed-up to 2 months after birth using key informants . Primary outcomes were maternal , perinatal and neonatal mortality . Clusters were health centre catchment areas assigned using stratified computer-generated r and omization . Following exclusions , including non-birthing facilities , 61 clusters were analysed : control ( 17 clusters , 4912 births ) , FI ( 15 , 5335 ) , CI ( 15 , 5080 ) and FI + CI ( 14 , 5249 ) . This trial was registered as International St and ard R and omised Controlled Trial [ IS RCT N18073903 ] . Outcomes for 14 576 and 20 576 births were recorded during baseline ( June 2007–September 2008 ) and intervention ( October 2008–December 2010 ) periods . Results For control , FI , CI and FI + CI clusters neonatal mortality rates were 34.0 , 28.3 , 29.9 and 27.0 neonatal deaths per 1000 live births and perinatal mortality rates were 56.2 , 55.1 , 48.0 and 48.4 per 1000 births , during the intervention period . Adjusting for clustering and stratification , the neonatal mortality rate was 22 % lower in FI + CI than control clusters ( OR = 0.78 , 95 % CI 0.60–1.01 ) , and the perinatal mortality rate was 16 % lower in CI clusters ( OR = 0.84 , 95 % CI 0.72–0.97 ) . We did not observe any intervention effects on maternal mortality . Conclusions Despite implementation problems , a combined community and facility approach using participatory women ’s groups and quality improvement at health centres reduced newborn mortality in rural Malawi BACKGROUND The effect of vitamin A supplementation on the survival of infants aged < 6 mo  is unclear . Because most infant deaths occur in the first few month of life , maternal supplementation may improve infant survival . OBJECTIVES The objective was to assess the effect of maternal vitamin A or beta-carotene supplementation on fetal loss and survival of infants < 6 mo of age . DESIGN Married women of reproductive age in 270 wards of Sarlahi district , Nepal , were eligible to participate . Wards were r and omly assigned to have women receive weekly doses of 7000 microg retinol equivalents as retinyl palmitate ( vitamin A ) , 42 mg all-trans-beta-carotene , or placebo . Pregnancies were followed until miscarriage , stillbirth , maternal death , or live birth of one or more infants , who were followed through 24 wk of age . RESULTS A total of 43559 women were enrolled ; 15832 contributed 17373 pregnancies and 15987 live born infants to the trial . The rate of fetal loss was 92.0/1000 pregnancies in the placebo group , comparable with rates in the vitamin A and beta-carotene groups , which had relative risks of 1.06 ( 95 % CI : 0.91 , 1.25 ) and 1.03 ( 95 % CI : 0.87 , 1.19 ) , respectively . The 24-wk mortality rate was 70.8/1000 live births in the placebo group , comparable with rates in the vitamin A and beta-carotene groups , which had relative risks of 1.05 ( 95 % CI : 0.87 , 1.25 ) and 1.03 ( 95 % CI : 0.86 , 1.22 ) , respectively . CONCLUSIONS Small weekly doses of vitamin A or beta-carotene given to women before conception , during pregnancy , and through 24 wk postpartum did not improve fetal or early infant survival in Nepal BACKGROUND Neonatal deaths in developing countries make the largest contribution to global mortality in children younger than 5 years . 90 % of deliveries in the poorest quintile of households happen at home . We postulated that a community-based participatory intervention could significantly reduce neonatal mortality rates . METHODS We pair-matched 42 geopolitical clusters in Makwanpur district , Nepal , selected 12 pairs r and omly , and r and omly assigned one of each pair to intervention or control . In each intervention cluster ( average population 7000 ) , a female facilitator convened nine women 's group meetings every month . The facilitator supported groups through an action-learning cycle in which they identified local perinatal problems and formulated strategies to address them . We monitored birth outcomes in a cohort of 28?931 women , of whom 8 % joined the groups . The primary outcome was neonatal mortality rate . Other outcomes included stillbirths and maternal deaths , uptake of antenatal and delivery services , home care practice s , infant morbidity , and health-care seeking . Analysis was by intention to treat . The study is registered as an International St and ard R and omised Controlled Trial , number IS RCT N31137309 . FINDINGS From 2001 to 2003 , the neonatal mortality rate was 26.2 per 1000 ( 76 deaths per 2899 livebirths ) in intervention clusters compared with 36.9 per 1000 ( 119 deaths per 3226 livebirths ) in controls ( adjusted odds ratio 0.70 [ 95 % CI 0.53 - 0.94 ] ) . Stillbirth rates were similar in both groups . The maternal mortality ratio was 69 per 100000 ( two deaths per 2899 livebirths ) in intervention clusters compared with 341 per 100000 ( 11 deaths per 3226 livebirths ) in control clusters ( 0.22 [ 0.05 - 0.90 ] ) . Women in intervention clusters were more likely to have antenatal care , institutional delivery , trained birth attendance , and hygienic care than were controls . INTERPRETATION Birth outcomes in a poor rural population improved greatly through a low cost , potentially sustainable and scalable , participatory intervention with women 's groups Background Maternal micronutrient deficiencies are widespread in Pakistan and are potentially associated with maternal undernutrition and intrauterine growth retardation . Intervention strategies largely consist of administration of iron – folic acid supplements during pregnancy . Objective We evaluated the acceptability of multiple micronutrient supplementation and its potential benefits on pregnancy outcomes and maternal micronutrient status in a cohort of pregnant women in rural and urban Sindh through a cluster-r and omized design . Methods We r and omly assigned 2,378 pregnant women to receive either iron – folic acid or multiple micronutrient supplements . The supplements were administered fortnightly by community health workers who performed home visits to assess tolerance and observe the mothers . Results The women in both groups consumed about 75 % of the supplements provided , and few reported adverse effects such as vomiting , abdominal pain , etc . There was a small ( 70 g ) but significant increase in birthweight among infants of mothers receiving multiple micronutrients as compared with infants of mothers receiving iron – folic acid supplements ( 2.95 ± 0.6 vs. 2.88 ± 0.5 kg , p = .01 ) . This translated into a 10 % reduction ( p < 0.17 ) in the proportion of low-birthweight infants among infants of mothers receiving multiple micronutrients . Although stillbirth rates were comparable in the two groups , the early neonatal mortality rate in the group receiving multiple micronutrients was higher , although not significantly , than that in the group receiving iron– folic acid ( 43.2 vs. 23.5 deaths per 1,000 live births ; RR = 1.64 ; 95 % CI , 0.94 to 2.87 ) . Comparable reductions in anemia ( hemoglobin < 11 g/dL ) were observed , although the proportion with low iron stores ( assessed by serum ferritin ) was lower in the iron – folic acid group in the postnatal period . Although the proportion of women with sub clinical vitamin A deficiency after supplementation did not differ between the two groups , the iron – folic acid group had a higher proportion with lower serum zinc levels in the immediate postpartum period . Conclusions These data suggest that multiple micronutrient supplements are well tolerated during pregnancy , but the effect on birthweight is modest . The observed effect on early neonatal mortality suggests the need for further studies and careful assessment of the intervention in health system setting CONTEXT Nutritional insult in fetal life and small size at birth are common in low-income countries and are associated with serious health consequences . OBJECTIVES To test the hypothesis that prenatal multiple micronutrient supplementation ( MMS ) and an early invitation to food supplementation would increase maternal hemoglobin level and birth weight and decrease infant mortality , and to assess whether a combination of these interventions would further enhance these outcomes . DESIGN , SETTING , AND PARTICIPANTS A r and omized trial with a factorial design in Matlab , Bangladesh , of 4436 pregnant women , recruited between November 11 , 2001 , and October 30 , 2003 , with follow-up until June 23 , 2009 . INTERVENTIONS Participants were r and omized into 6 groups ;  a double-masked supplementation with capsules of 30 mg of iron and 400 μg of folic acid , 60 mg of iron and 400 μg of folic acid , or MMS containing a daily allowance of 15 micronutrients , including 30 mg of iron and 400 μg of folic acid , was combined with food supplementation ( 608 kcal 6 days per week ) r and omized to either early invitation ( 9 weeks ' gestation ) or usual invitation ( 20 weeks ' gestation ) . MAIN OUTCOME MEASURES Maternal hemoglobin level at 30 weeks ' gestation , birth weight , and infant mortality . Under 5-year mortality was also assessed . RESULTS Adjusted maternal hemoglobin level at 30 weeks ' gestation was 115.0 g/L ( 95 % CI , 114.4 - 115.5 g/L ) , with no significant differences among micronutrient groups . Mean maternal hemoglobin level was lower in the early vs usual invitation groups ( 114.5 vs 115.4 g/L ; difference , -0.9 g/L ; 95 % CI , -1.7 to -0.1 ; P = .04 ) . There were 3625 live births out of 4436 pregnancies . Mean birth 
    Output:
    
Supplementation with multiple micronutrients , kangaroo mother care , and maternal supplementation with vitamin A did not decrease neonatal mortality .
A few heterogeneous community-based interventions demonstrated a decrease in neonatal mortality
