Objective: This pilot study evaluated a cost neutral, integrated Special Supplemental Nutrition Program for Women Infants and Children (WIC) and obstetrical service model designed to prevent postpartum weight retention in obese women.Methods: A sample of women who received benefits from the Johns Hopkins (JH) WIC program and prenatal care from the JH Nutrition in Pregnancy Clinic, which provides obstetrical care for women with a BMI ≥ 30 kg/m2, participated in the WICNIP randomized clinical trial. Intervention participants received enhanced nutrition services and education at five visits and during one phone call between delivery and 6 months postpartum. Control participants received standard WIC services. Weight data was collected for all participants at multiple time points: pre-pregnancy, delivery, and postpartum at 4, 6 weeks, 4, and 6 months. Maternal socio-demographic factors, obesity class and the number of education contacts received were also recorded.Results: Fifty-three African-American women were randomized into the intervention and control groups. Intervention participants retained significantly less gestational weight gain than control participants (3.0 ± 11.8 vs. 12.6 ± 20.4, p < 0.05). In both groups, participants with Class III obesity retained significantly less weight than participants in Classes I and II (p = 0.02).Conclusions for Practice: An integrated WIC and obstetrical service model is feasible and can limit postpartum weight retention in obese women. Weight retention at 6 months postpartum between intervention and control participants was statistically significant. Further research should explore targeted interventions by obesity class to address weight retention for low-income, African American women who participate in WIC. [ABSTRACT FROM AUTHOR]

Purpose of Review To evaluate the clinical and nutritional significance of genetically determined lactase nonpersistence and potential lactose and milk intolerance in 65–70% of the world’s adult population. Recent Findings Milk consumption is decreasing in the USA and is the lowest in countries with a high prevalence of lactase non-persistence. The dairy industry and Minnesota investigators have made efforts to minimize the influence of lactose intolerance on milk consumption. Some lactose intolerant individuals, without co-existent irritable bowel syndrome, are able to consume a glass of milk with a meal with no or minor symptoms. The high frequency of lactase persistence in offspring of Northern European countries and in some nomadic African tribes is due to mutations in the promoter of the lactase gene in association with survival advantage of milk drinking. Summary Educational and commercial efforts to improve calcium and Vitamin D intake have focused on urging consumption of tolerable amounts of milk with a meal, use of lowered lactose-content foods including hard cheeses, yogurt, and lactose-hydrolyzed milk products.

This cross-sectional study examines Maryland's women, infants, and children (WIC) breastfeeding initiation rates by program participation. The authors report on data regarding demographic and health characteristics and infant feeding practices for infants (n = 18 789) newly WIC-certified from January 1, 2007 to June 30, 2007. The authors compared self-reported, breastfeeding initiation rates for 3 groups: peer counselor (PC-treatment group) and two comparison groups, lactation consultant (LC), and standard care group (SCG). Reported breastfeeding initiation at certification was 55.4%. Multiple logistic regression analysis, controlling for relevant maternal and infant characteristics, showed that the odds of breastfeeding initiation were significantly greater among PC-exposed infants (OR [95% CI] 1.27 [1.18, 1.37]) compared to the reference group of SCG infants, but not significantly different between LC infants (1.04 [0.96, 1.14]) and the SCG. LC and SCG infants had similar odds of breastfeeding initiation. In the Maryland WIC program, breastfeeding initiation rates were positively associated with peer counseling. [ABSTRACT FROM AUTHOR]

Objective: This paper reports on the status of lactose digestion during early and late pregnancy and at 8 weeks postpartum in an African-American population. The hypothesis is that lactose digestion and milk tolerance do not change throughout pregnancy and do not differ from those of non-pregnant African-American women.Design and Subjects: This longitudinal study determined lactose digestion after ingesting 240 ml of 1% fat milk containing 12 g of lactose at: (1) early pregnancy, prior to 16 weeks (n=148); (2) late pregnancy, 30-35 weeks (n=77); and (3) 8 weeks postpartum (n=93). One hundred and one comparably matched non-pregnant African-American women served as controls.Results: Prevalence of lactose digestion, as measured by breath hydrogen, was 80.2% in the control women, 66.2% in early pregnancy, 68.8% in late pregnancy and 75.3% postpartum. The prevalence of women reporting symptoms was approximately 20% regardless of lactose absorption status. However, the control women reported significantly more symptoms than did the pregnant women.Conclusions: This study indicates that there is no significant change in lactose digestion during pregnancy. The prevalence of lactose intolerance for the pregnant African-American women studied is similar to that for non-pregnant African-American women and similar to previous prevalence reports in adult African-Americans. There was no change in the tolerance of lactose noted during pregnancy in these women. There were, however, fewer symptoms reported by the lactose-maldigesting pregnant women. [ABSTRACT FROM AUTHOR]

To examine how individuals within a woman's life influence her infant feeding intention, we interviewed 441 African-American women on the breastfeeding attitudes and experiences of their friends, relatives, mother, and the baby's father. Women were interviewed at entry into prenatal care at clinics associated with one of four Baltimore WIC clinics chosen for a breastfeeding promotion project. Qualitative data were also collected among 80 women. Friends and "other" relatives were not influential. Grandmothers' opinions and experiences were important, but their influence was reduced after considering the opinion of the baby's father. The opinion of the woman's doctor was an independent predictor of infant feeding intention. Breastfeeding promotion programs should recognize the separate influence of fathers, health providers, and grandmothers in women's infant feeding decisions. [ABSTRACT FROM PUBLISHER]

Wang X (Environmental Epidemiology Program, Department of Environmental Health, Harvard School of Public Health, Boston, MA 02115, USA) Guyer B and Paige D M. Differences in gestational age-specific birthweight among Chinese, Japanese and White Americans. 1994; 23: 119–128. This study investigated racial differences in gestational age-specific birthweight in a sample of 21 288 Chinese, 11 882 Japanese and 65818 White resident singleton livebirths, obtained from the National Center for Health Statistics 1983 and 1984 linked birth/infant death cohort files. The gestational age-specific birthweight distributions of Chinese and Japanese were similar, but differed from those of Whites both in the mean level and in the variance. The mean birth-weights of Chinese and Japanese as compared to that of White infants were 4–5% lower among preterm births, and 5–6% lower among term births, after adjustment was made for gestational age, demographic variables, use of antenatal care and infant gender. The racial differences in gestational age-specific birthweight were even greater at the 90th percentile but smaller at the 10th percentile. These racial differences should be considered in both clinical evaluation of newborns and in epidemiological studies. Significant interactions were found between race and such maternal variables as education, marital status, birthplace, and month during which antenatal care began. It suggests that recognition of racial differences in risk factors and exposure-response relationships may be valuable in specifying interventions for intrauterine growth retardation among different racial groups.

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. [ABSTRACT FROM PUBLISHER]

The infant feeding preferences of significant others have been shown to influence a pregnant woman's breastfeeding decision. Many researchers and policy makers are calling for the inclusion of a woman's significant other in the counseling and education of pregnant women regarding breastfeeding. This study reports on the impact of the significant other's infant feeding preferences and beliefs on a woman's intention to breastfeed, her initiation and successful initiation (longer than seven days) of breastfeeding. "Significant other" was defined as the person whom the pregnant woman reported as the one whose opinion "mattered the most to her" regarding feeding her infant. A randomly selected sub-sample of 133 women and their significant others was chosen from a larger infant feeding study. This sub-sample was heterogeneous with respect to age, education, and marital status. The women were interviewed during their third trimester of pregnancy and again at 7-10 days postpartum. Their significant others (71 percent baby's father and 29 percent baby's maternal grandmother), were interviewed during the woman's third trimester of pregnancy. Results indicate that a woman's intention to breastfeed is strongly and positively affected by the significant other's infant feeding preferences, initiation of breastfeeding is mediated through intention to breastfeed, and successful initiation of breastfeeding is also mediated through intention and is uniquely dependent on the pregnant woman's self-efficacy.

The purpose of the current research was to identify demographic and psychosocial factors important in the decision to breastfeed among a sample of WIC participants in a rural area. One hundred and ninety-eight women completed both a prenatal interview during their third trimester of pregnancy and a second interview within one to three weeks postpartum. Twenty-seven percent of these WIC participants initiated breastfeeding. Multiple logistic regression analysis revealed that prenatal behavioral beliefs about the consequences of breastfeeding and formula feeding were the strongest predictors of breastfeeding initiation. The results suggest that education to improve the current low rates of breastfeeding among WIC participants should emphasize that formula feeding is neither more convenient nor easier than breastfeeding, and that breastfeeding need not limit mothers in public or social settings.

Initial triage is carried out by a health aide using observation and scoring of objective clinical findings, and the patient is referred either to a physician or a nurse pediatric practitioner. Further decisions are made by the nurse practitioner. Evaluation of 1,500 patient visits indicates the value of this system. [ABSTRACT FROM AUTHOR]

Certain Negro children who reject milk exhibit biologic differences from other children. These factors operate beyond the social and economic determinants that act against the consumption of milk. It appears that the number of such children is large enough to call for a review of the efficacy of present milk programs. [ABSTRACT FROM AUTHOR]
