    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 We evaluated the single and combined effects of introducing a motivational video and peer counseling into four matched WIC clinics on breastfeeding initiation and continuation at 7 - 10 days among African-American WIC participants . Of the 242 women with complete data , 48 % initiated breastfeeding , but only 31 % were still breastfeeding at 7 - 10 days . Initiation was associated with cesarean delivery , infant feeding instruction , no artificial milk discharge pack , attending the peer counselor only-intervention site , and intention to breastfeed . Continuation was influenced by infant feeding instruction , no artificial milk discharge pack , and intention to breastfeed . Overall , trends toward a positive impact of the breastfeeding promotion activities were evident but weak , and largely gone by 7 - 10 days postpartum Objective : To evaluate the effectiveness of a lay delivered intervention to reduce Latino children ’s exposure to environmental tobacco smoke ( ETS ) . The a priori hypothesis was that children living in households that were in the intervention group would have lower exposure over time than measurement only controls . Design : A two group , r and omised control trial was conducted . Setting : Areas of San Diego county with a large Latino population . Participants : 143 Latino parent – child pairs . Intervention : Trained bicultural and bilingual Latina lay community health advisors , or promotoras , conducted problem solving aim ed at lowering the target child ’s exposure to ETS in the household . Six home and telephone sessions were delivered by the promotoras over a four month period . Main outcome measures : Outcome measures were collected at baseline , immediately post-intervention , three months post-intervention , and 12 months post-intervention . Four outcomes were considered : ( 1 ) parent ’s paper- and -pencil reports of the child ’s past month exposure ; ( 2 ) hair sample s from the child analysed for past month nicotine ; ( 3 ) hair sample s from the child analysed for past month cotinine ; and ( 4 ) per cent confirmed reducers . Results : There were no significant condition-by-time interactions , the term indicative of a differential intervention effect . Significant or near significant time main effects were seen for children ’s hair cotinine , per cent confirmed reducers , and , in particular , parent reports of exposure . Conclusions : Applying a lay promotora model to deliver the behavioural problem solving intervention unfortunately was not effective . A likely explanation relates to the difficulty of delivering a relatively complex intervention by lay women untrained in behaviour change theory and research methods OBJECTIVE To assess the effectiveness of a volunteer-driven outreach program on immunization rates in children younger than 2 years . DESIGN R and omized controlled trial . SETTING Pediatric ambulatory clinics in New York , NY . PATIENTS A total of 163 children were r and omly assigned to receive services from the volunteer-driven outreach program  or to serve as control subjects . All children were ( 1 ) younger than 2 years , ( 2 ) no-shows for a scheduled appointment in the pediatric clinic , and ( 3 ) due or overdue for a vaccine . INTERVENTION Immunization outreach , tracking , and follow-up were provided by community volunteers throughout follow-up ( mean , 6.5 months ) . Control children were notified of immunization status at enrollment but received no further contact until the conclusion of follow-up ( mean , 6.4 months ) . MAIN OUTCOME MEASURE Immunization status 6 months after enrollment . RESULTS Significantly more intervention children were up-to- date with their vaccination series than controls ( 75 % vs. 54 % ; P = .03 ) . Children in the control group were 2.8 times more likely to be late for a vaccine than intervention children ( odds ratio = 2.8 ; P = .02 ) . In addition , an immunization delay of longer than 30 days at enrollment was a significant predictor of final immunization delay ( odds ratio = 2.6 ; P = .02 ) . CONCLUSIONS This volunteer-driven program significantly improved immunization rates among intervention children compared with controls . Results confirm previous findings that indicate an increased risk of an incomplete immunization series by 2 years of age among children who fall behind early in their primary vaccination series . However , control children were almost 3 times more likely to be late ( for > or = 1 vaccines ) than intervention children , regardless of whether an earlier immunization delay was present BACKGROUND The purpose of this demonstration project was to test the effectiveness of a volunteer peer counseling program for promoting breastfeeding in a community . METHODS The two-year project was conducted in Iowa from September 1994 to September 1996 . Both intervention and control groups were rural low-income pregnant and postpartum women who qualified for the Women , Infants and Children 's ( WIC ) nutritional program . The intervention was initiated in two counties with 143 clients , of whom 72 completed the project . The control group was drawn from six counties that had received no significant breastfeeding promotion programs during the previous three years . The intervention was the assignment of trained volunteers with previous successful personal experience with breastfeeding as peer counselors  to low-income pregnant women . Both before and after the baby was born , the volunteers taught a series of in-home , one-to-one lessons about healthy diet and breastfeeding , and maintained informal contact to answer questions or help with concerns . RESULTS Women in the intervention group improved dietary intake when compared with the control group . Knowledge of breastfeeding and good nutrition improved slightly . Eighty-two percent of intervention compared with 31 percent of control group women initiated breastfeeding . Mean duration of breastfeeding for intervention and control group women was 5.7 and 2.5 weeks , respectively . At 4 weeks , 56 percent of intervention and 10 percent of control group women were still breastfeeding . CONCLUSION A volunteer peer counseling program that provides low-income women with role models , accurate information , support , and encouragement can increase the duration of breastfeeding , and thus contribute to healthier infants BACKGROUND Breastfeeding can ameliorate some of the complex health issues faced by low-income families . Women who breastfeed and their infants have lower health care costs compared with those who formula feed . Increasing the duration of breastfeeding is recognized as a national priority , particularly for low-income women . This community-based r and omized clinical trial involving low-income mothers compared usual care with an intervention comprising hospital and home visits , and telephone support by a community health nurse/peer counselor team for 6 months after delivery . METHODS Forty-one women were recruited after delivery of a full-term singleton infant and r and omly assigned to intervention or usual care groups . RESULTS Women receiving the community health intervention  breastfed longer than the women receiving usual care . The infants in the intervention group had fewer sick visits and reported use of fewer medications than infants in the usual care group . The intervention cost ( $ 301/mother ) was partially offset by cost savings on formula and health care . CONCLUSIONS Community health nurse and peer counselor support can increase breastfeeding duration in low-income women , and has the potential to reduce total costs including the cost of support OBJECTIVE To assess the efficacy of peer counseling to promote exclusive breastfeeding ( EBF ) among low-income inner-city women in Hartford , Conn. DESIGN Participants recruited prenatally were r and omly assigned to either receive support for EBF from a peer counselor plus conventional breastfeeding support ( peer counseling group [ PC ] ) or only conventional breastfeeding support ( control group [ CG ] ) and followed through 3 months post partum . SETTING Low-income predominantly Latina community . PARTICIPANTS Expectant mothers , less than 32 weeks gestation and considering breastfeeding ( N = 162 ) . Intervention Exclusive breastfeeding peer counseling support offering 3 prenatal home visits , daily perinatal visits , 9 postpartum home visits , and telephone counseling as needed . MAIN OUTCOME MEASURES Exclusive breastfeeding rates at hospital discharge , 1 , 2 , and 3 months post partum ( n = 135 ) . RESULTS At hospital discharge , 24 % in the CG compared with 9 % in the PC had not initiated breastfeeding , with 56 % and 41 % , respectively , nonexclusively breastfeeding . At 3 months , 97 % in the CG and 73 % in the PC had not exclusively breastfed ( relative risk [ RR ] = 1.33 ; 95 % CI , 1.14 - 1.56 ) during the previous 24 hours . The likelihood of nonexclusive breastfeeding throughout the first 3 months was significantly higher for the CG than the PC ( 99 % vs 79 % ; RR = 1.24 ; 95 % CI , 1.09 - 1.41 ) . Mothers in the CG were less likely than their PC counterparts to remain amenorrheic at 3 months ( 33 % vs 52 % ; RR = 0.64 ; 95 % CI , 0.43 - 0.95 ) . The likelihood of having 1 or more diarrheal episode in infants was cut in half in the PC ( 18 % vs 38 % ; RR = 2.15 ; 95 % CI , 1.16 - 3.97 ) . CONCLUSION Well-structured , intensive breastfeeding support provided by hospital and community-based peer counselors is effective in improving exclusive breastfeeding rates among low-income , inner-city women in the United States BACKGROUND Breastfeeding peer counseling has improved breastfeeding rates in developing countries ; however , its impact in this country has not been adequately evaluated . OBJECTIVE To evaluate the effectiveness of an existing , breastfeeding peer counseling program within the United States . DESIGN R and omized , prospect i ve , controlled trial in which participants were recruited prenatally and r and omly assigned to receive either routine breastfeeding education or routine breastfeeding education plus peer counseling . SETTING An urban hospital serving a large population of low-income Latinas . PARTICIPANTS Pregnant women ( < or = 26 weeks ' gestation ) were recruited from the hospital 's prenatal clinic . Inclusion criteria specified that participants be low income , be considering breastfeeding , have delivered a healthy , full-term singleton , and have access to a telephone . Intervention Breastfeeding peer counseling services included 1 prenatal home visit , daily perinatal visits , 3 postpartum home visits , and telephone contact as needed . MAIN OUTCOME MEASURES Breastfeeding rates at birth and 1 , 3 , and 6 months postpartum . RESULTS The proportion not initiating breastfeeding was significantly lower in the intervention group than among controls ( 8/90 [ 9 % ] vs 17/75 [ 23 % ] ; relative risk , 0.39 ; 95 % confidence interval , 0.18 - 0.86 ) . The probability of stopping breastfeeding also tended to be lower in the intervention group at both 1 month ( 36 % vs 49 % ; relative risk , 0.72 ; 95 % confidence interval , 0.50 - 1.05 ) and 3 months ( 56 % vs 71 % ; relative risk , 0.78 ; 95 % confidence interval , 0.61 - 1.00 ) . CONCLUSION These findings demonstrate that , in the United States , peer counselors can significantly improve breastfeeding initiation rates and have an impact on breastfeeding rates at 1 and 3 months post partum This research examined the effect of peer support on  breastfeeding duration and exclusivity ( breastfeeding without supplements )  in a population of low-income women during the first 3 months postpartum . Participants in the peer counselor group ( n = 18 ) exhibited higher rates of exclusive breastfeeding across time than those without a counselor ( n = 18 ) , and more exclusive breastfeeding was associated with long duration overall . Mother 's career plans had the greatest effect on duration of breastfeeding .  Women who intended to return to work , attend school , or both breastfed 6 to 9 weeks less than participants who intended to stay home . Attendance at a breastfeeding class and knowing someone who had breastfed was significantly correlated with a longer duration of breastfeeding . Nutritionists from the Women , Infants and Children ( WIC ) Program were the primary source of breastfeeding information . Two main factors discouraged women from breastfeeding : returning to work , school , or both and the perception of a diminished milk supply . Greater emphasis should be placed on prenatal breastfeeding education for low-income women , and their mothers and gr and mothers should be included . Peer support is one important component of social support in the area of breastfeeding that community health nurses ( CHNs ) can utilize . CHNs are in a unique position to assist working moth
