    Input: Breastfeeding rates among low-income women in the east-south- central United States are among the lowest in the country . This study examined the effect of a peer counseling program on breastfeeding initiation and duration in a low-income rural population in West Tennessee . A postpartum survey and chart review were conducted with WIC clients at nine health departments . Response rate was 99 % ( 291/293 ) .  Breastfeeding initiation and duration at 6 weeks were increased in the peer counselor group ( n= 156 ) compared with women in the no-peer counselor group ( n= 135 ) ( 53 % vs. 33%,p<0.001 , and 26 % vs. 13%,p=0.006 , respectively ) . Multivariate analysis revealed that women in the peer counselor group were significantly more likely to initiate breastfeeding ( OR=2.43 , 95 % CI=1.23 - 4.67 ) and to be breastfeeding at 6 weeks ( OR=2.78 , 95 % CI=2.08 - 9.5 1 ) , than those in the no-peer counselor group Abstract Objectives : To establish the relative cost effectiveness of postnatal support in the community in addition to the usual care provided by community midwives . Design : R and omised controlled trial with six month follow up . Setting : Recruitment in a university teaching hospital and care provided in women 's homes . Participants : 623 postnatal women allocated at r and om to intervention ( 311 ) or control ( 312 ) group . Intervention : Up to 10 home visits in the first postnatal month of up to three hours duration by a community postnatal support worker . Main outcome measure : General health status as measured by the SF-36 and risk of postnatal depression . Breast feeding rates , satisfaction with care , use of services , and personal costs . Results : At six weeks there was no significant improvement in health status among the women in the intervention group . At six weeks the mean total NHS costs were £ 635 for the intervention group and £ 456 for the control group ( P=0.001 ) . At six months figures were £ 815 and £ 639 ( P=0.001 ) . There were no differences between the groups in use of social services or personal costs . The women in the intervention group were very satisfied with the support worker visits . Conclusions : There was no health benefit of additional home visits by community postnatal support workers compared with traditional community midwifery visiting as measured by the SF-36 . There were no savings to the NHS over six months after the introduction of the community postnatal support worker service BACKGROUND Most mothers breastfeed in Bangladesh , but they rarely practise exclusive breastfeeding . Hospital-based strategies for breastfeeding promotion can not reach them because about 95 % have home deliveries . We postulated that with the intervention of trained peer counsellors , mothers could be enabled to breastfeed exclusively for the recommended duration of 5 months . METHODS 40 adjacent zones in Dhaka were r and omised to intervention or control groups . Women were enrolled during the last trimester of pregnancy between February and December , 1996 . In the intervention group , 15 home-based counselling visits were scheduled , with two visits in the last trimester , three early postpartum ( within 48 h , on day 5 , between days 10 and 14 ) , and fortnightly thereafter until the infant was 5 months old . Peer counsellors were local mothers who received 10 days ' training . FINDINGS 363 women were enrolled in each group .  Peer counselling significantly improved breastfeeding practice s. For the primary outcome , the prevalence of exclusive breastfeeding at 5 months was 202/228 ( 70 % ) for the intervention group and 17/285 ( 6 % ) for the control group ( difference=64 % ; 95 % CI 57%-71 % , p>0.0001 ) . For the secondary outcomes , mothers in the intervention group initiated breastfeeding earlier than control mothers and were less likely to give prelacteal and postlacteal foods . At day 4 , significantly more mothers in the intervention group breastfed exclusively than controls . INTERPRETATION Peer counsellors can effectively increase the initiation and duration of exclusive breastfeeding . We recommend incorporation of peer counsellors in mother and child health programmes in developing countries To assess the impact on child growth of the nutrition-counseling component of the Integrated Management of Childhood Illnesses ( IMCI ) strategy , a r and omized trial was implemented . All 28 government health centers in a Southern Brazil city were paired according to baseline nutritional indicators . One center from each pair was r and omly selected and its doctors received 20-h training in nutrition counseling .  Thirty-three doctors were included and 12 - 13 patients < 18 mo of age from each doctor were recruited . The study included testing the knowledge of doctors , observing consultations and visiting the children at home 8 , 45 and 180 d after the initial consultation . Maternal knowledge , practice s and adherence to nutritional recommendations were assessed , and anthropometric measurements were taken . Day-long dietary intake was evaluated on a sub sample of children . Doctors in the intervention group had better knowledge of child nutrition and improved assessment and counseling practice s. Maternal recall of recommendations was higher in the intervention than in the control group , as was satisfaction with the consultation . Reported use of recommended foods was also increased . Daily fat intake was higher in the intervention than in the control group ; mean daily intakes of energy and zinc also tended to improve . Children 12 mo of age or older had improved weight gain and a positive but nonsignificant improvement in length .  Nutrition-counseling training  improved doctors ' performances , maternal practice s and the diets and weight gain of children . The r and omized design with blind outcome evaluation strongly supports a causal link . These results should be replicated in other setting Exclusive breast-feeding ( EBF ) rates remain low despite numerous health benefits associated with this behavior . We conducted a r and omized trial on the effect of lactation counseling on EBF , which controlled for the Hawthorne effect while also varying the timing of the intervention . Pregnant women attending prenatal clinics in Tema were r and omly assigned to 1 of 2 intervention groups ( IG ) or to a control group ( C ) , as follows : 1 ) EBF support given pre- , peri- , and postnatally ( IG1 ; n = 43 ) ; 2 ) EBF support given only peri- and postnatally ( IG2 ; n = 44 ) ; or 3 ) nonbreast-feeding health educational support ( C ; n = 49 ) that had an equal amount of contact with lactation counselors . Two educational sessions were provided prenatally , and 9 home follow-up visits were provided in the 6-mo postpartum period . Infant feeding data were collected monthly at the participant 's home . The 3 groups did not differ in sociodemographic characteristics . At 6 mo postpartum , 90.0 % in IG1 and 74.4 % in IG2 had exclusively breast-fed during the previous month . By contrast , only 47.7 % in C were doing so ( P = 0.008 ) . Similarly , the percentage of EBF during the 6 mo was significantly higher ( P = 0.02 ) among IG1 and IG2 ( 39.5 % ) than among C ( 19.6 % ) . The 100 % increase in EBF rates can be attributed to the lactation counseling provided . Additional prenatal EBF support may not be needed within a context of strong routine prenatal EBF education CONTEXT Promotion of breastfeeding in Brazilian maternity hospitals . OBJECTIVE To quantify changes in the breastfeeding duration among mothers served by hospitals exposed to the Wellstart-SLC course  , comparing them with changes among mothers attended by institutions not exposed to this course . DESIGN R and omized Institutional Trial . SETTING The effects of training on breastfeeding duration was assessed in eight Brazilian hospitals assigned at r and om to either an exposed group ( staff attending the Wellstart-SLC course ) or a  control group .  SAMPLE For each of the eight study hospitals , two cohorts of about 50 children were visited at home at one and six months after birth . The first cohort ( n = 494 ) was composed of babies born in the month prior to exposure to the Wellstart-SLC course , and the second cohort ( n = 476 ) was composed of babies born six months subsequent to this exposure . MAIN MEASUREMENTS Kaplan-Meier curves were plotted to describe the weaning process and log-rank tests were used to assess statistical differences among survival curves . Hazard ratio ( HR ) estimates were calculated by fitting Cox proportional hazard regression models to the data . RESULTS The increases in estimated , adjusted rates for children born in hospitals with trained personnel were 29 % ( HR = 0.71 ) and 20 % ( HR = 0.80 ) for exclusive and full breastfeeding , respectively . No changes were identified for total breastfeeding . CONCLUSION This r and omized trial supports a growing body of evidence that training hospital health professionals in breastfeeding promotion and protection results in an increase in breastfeeding duration The effect of prenatal breastfeeding education on breastfeeding incidence and duration was determined among 31 prenatal WIC participants . The subjects , assigned to a control group  ( n= 17 ) or experimental group  ( n= 14 ) , received prenatal nutrition education through the WIC program . The experimental group received at least one breastfeeding education class . There was no significant difference in breastfeeding incidence between the groups , however , there was a significant difference in breastfeeding incidence by parity ( p<0.05 ) . There was a significantly higher percentage of women still breastfeeding at 3 and 4 months postpartum in the experimental versus the control group ( p<0.05 ) . The control group breastfed for 29.5 + 43.6 days , while the experimental group breastfed for 76 days + 104.3 ( p=.05 ) . Multiparous women who had bottle-fed previous children breastfed for a shorter duration ( 18 + 22 days ) than primiparous women ( 60 87 days ) ( p<.07 ) To assess the feasibility of a pediatric primary care based intervention to promote healthful behaviors among 0–6 month old infants and their mothers . We enrolled  two intervention practice s ( 60 mother-infant pairs ) and one usual care control practice ( 24 pairs ) in a non-r and omized controlled trial . We completed visits and interviews with 80 ( 95 % ) pairs at birth and 6 months . The intervention included ( 1 ) brief focused negotiation by pediatricians , ( 2 ) motivational counseling by a health educator , and ( 3 ) group parenting workshops . We evaluated the intervention effects on infant feeding , sleep duration , TV viewing , and mothers ’ responsiveness to satiety cues . Maternal behavioral targets included postpartum diet , physical activity , TV and sleep . At 6 months , fewer intervention than control infants had been introduced to solid foods ( 57 % vs. 82 % ; P = 0.04 ) , and intervention infants viewed less TV ( mean 1.2 vs. 1.5 h/d ; P = 0.07 ) . Compared to control infants , intervention infants had larger increases in their nocturnal sleep duration from baseline to follow up ( mean increase 1.9 vs. 1.3 h/d ; P = 0.05 ) ; larger reductions in settling time ( mean reduction −0.70 vs. −0.10 h/d ; P = 0.02 ) ; and larger reductions in hours/day of nighttime wakefulness ( mean reduction −2.9 vs. −1.5 h/d ; P = 0.08 ) . There were no differences in breastfeeding , response to satiety cues , or maternal health behaviors . A program of brief focused negotiation by pediatricians , individual coaching by health educators using motivational interviewing , and group parenting workshops tended to improve infant feeding , sleep and media exposure , but had less impact on mothers ’ own health-related behaviors OBJECTIVE Maternal obesity is associated with poor breastfeeding outcomes , yet no intervention has been developed to improve them . To ascertain whether increased breastfeeding support or provision of a breast pump is a feasible , effective intervention to improve breastfeeding , we enrolled obese women who intended to breastfeed in two r and omized trials . METHODS In Bassett Improving Breastfeeding Study ( BIBS ) 1 , 40 women received targeted breastfeeding support in the hospital  and via telephone or usual care .  Information regarding breastfeeding was collected via telephone for 7 days after delivery and at 30 and 90 days postpartum . In BIBS 2 , 34 obese mothers received a manual or electric breast pump to use for 10 - 14 days or no pump ; data collection was similar . RESULTS In both experiments , r and omization failed to distribute women of differing postpartum body mass index adequately among the treatment groups . When analyses were adjusted for this , there was no difference in BIBS 1 between targeted and usual care groups and in BIBS 2 among the treatment groups in the proportion of women still breastfeeding at the times studied . CONCLUSIONS In future studies of obese women , stratified r and omization may be necessary . Further development of interventions to help obese women achieve optimal breastfeeding outcomes is required Objective To assess the effectiveness of an antenatal service using community based breastfeeding peer support workers on initiation of breast feeding . Design Cluster r and omised controlled trial . Setting Community antenatal clinics in one primary care trust in a multiethnic , deprived population . Participants 66 antenatal clinics with 2511 pregnant women : 33 clinics including 1140 women
