Breast-feeding is important in the health and nutrition of children, particularly those from lower socioeconomic groups. An objective of the Georgia Special Supplemental Food Program for Women, Infants, and Children (WIC) is to encourage breast-feeding among women participants. The rates of breast-feeding were assessed for 404 among 2,010 women who attended the WIC prenatal clinic in 1986 and gave birth in February 1987. The women were interviewed six months after childbirth. The results showed that 24 percent of women started breast-feeding, but only 6 percent continued to breast-feed for six months or longer. Women who started breast-feeding tended to have more education and tended to be married. Women who were married or living as married were three times more likely to breast-feed than women who were single or not living as married. The likelihood of breast-feeding was 5.2 times greater among the women with more than 12 years of education; 2.7 times greater for women with 12 years; and 2.5 times greater for women with 10 to 11 years, compared with women with nine or fewer years of education. Ethnic background, number of prior pregnancies, age, and employment status did not influence the decision to breast-feed in this low-income population. These findings of low incidence and short duration of breast-feeding indicate a need for the promotion of breast-feeding among women in this population.

Infant feeding was examined in 492 children in a population-based survey conducted in a low-income, urban county of St Paul, Minn. Of 41 Southeast Asian infants who were foreign born, 93% (38) had been breast-fed compared with 10% (12) of Southeast Asian infants born in the United States (n = 116). Among non-Southeast Asian infants, 73% (173) of whites (n = 237), 63% (27) of blacks (n = 43) and 65% (36) of other ethnic groups (n = 55) had been breast-fed. Among the non-Southeast Asian infants, the initiation of breast-feeding was associated with higher parental education and with being married. Ethnic group, level of poverty, and participation in the Supplemental Food Program for Women, Infants, and Children during pregnancy did not appear to influence the initiation of breast-feeding. The findings indicate a higher incidence of breast-feeding than in previous surveys of low-income black and white women; however, this may reflect the higher educational level of the non-Southeast Asian study population. In contrast, the sharp decline in the incidence of breast-feeding among Southeast Asian infants who were born in the United States compared with those who were foreign born indicates the need for public health approaches to strengthen traditional breast-feeding practices.

Abstract Background There is limited population-based data on diet and physical activity behaviors and weight loss among users of prescription weight loss medications. Most findings are from clinical settings or from research that includes organized behavioral programs. Methods We analyzed data from the 1998 Behavioral Risk Factor Surveillance System, an annual telephone survey conducted in all fifty states, the District of Columbia and Puerto Rico. The sample consisted of 135,435 noninstitutionalized adults aged 18 years old and older. We determined the prevalence and odds of prescription weight loss medication use, odds of 10% weight loss, and among current weight loss medication users, the prevalence and odds for diet and physical activity behaviors. Results 10.2% of obese women and 3.1% of obese men reported using prescription weight loss medications in the past 2 years. Of users, 28.2% had lost at least 10% of their pretreatment body weight. The odds of losing at least this much weight were higher among women, those who usually consumed ≥ 5 fruits and vegetables daily and those who met physical activity recommendations. Among current prescription weight loss medication users, 26.7% reported both eating fewer calories and meeting recommended leisure-time physical activity levels ( Conclusions Only 26.7% of prescription weight loss medication users reported following recommended diet and physical activity behaviors. Further research is needed to assess whether behavioral changes are associated with greater weight loss and maintenance among prescription weight loss medication users.

Abstract Background Several studies have shown that girls who undergo menarche at a relatively young age tend to be more obese as adults. However, because childhood (pre-menarcheal) levels of weight and height are associated with an earlier menarche, the increased prevalence of adult obesity among early maturers may largely reflect the persistence of childhood obesity into adulthood. Methods We examined these interrelationships among 1179 girls (65% white, 35% black) who were examined as children (mean age, 9 y), adolescents, and adults (mean age, 26 y) in the Bogalusa Heart Study. Results Both white and black women who reported that they underwent menarche before age 12 y had, on average, higher adult levels of weight (+10 kg), body mass index (BMI, +4 kg/m2) and skinfold thicknesses (+6 mm) than did women who underwent menarche after age 13.5 y. However, relatively fat children tended to undergo menarche earlier than did thinner children, with each standard deviation increase in pre-menarcheal BMI increasing the odds of early menarche ( Conclusions Although additional longitudinal studies are needed, it is likely that the importance of early menarche in adult obesity has been overestimated. Most of apparent influence of menarcheal age on adult obesity is attributable to the association of childhood obesity with both menarcheal age and adult obesity.

In this secondary analysis of data from a double-blind randomized controlled trial carried out in northern China, we aimed to assess the effect of prenatal supplementation with multiple micronutrients (MMN) or iron + folic acid (IFA), versus folic acid (FA) alone, on risk of spontaneous preterm birth (SPB) and the impact of supplementation timing on SPB. A total of 18,775 nulliparous pregnant women enrolled between 2006 and 2009 were randomly assigned to receive daily FA, IFA, or MMN from the period before 20 weeks' gestation to delivery. The incidences of SPB for women consuming FA, IFA, and MMN were 5.7%, 5.6% and 5.1%, respectively. Compared with women given FA, the relative risks of SPB for those using MMN and IFA were 0.99 (95% confidence interval: 0.85, 1.16) and 0.89 (95% confidence interval: 0.79, 1.05), respectively. SPB incidence in women who started consuming FA, IFA, and MMN before the 12th week of gestation (4.6%, 4.2%, and 3.9%, respectively) was significantly reduced compared with starting supplement use on or after the 12th gestational week (6.9%, 7.2%, and 6.4%, respectively). Starting use of FA, IFA, or MMN supplements before the 12th week of gestation produced a 41%-45% reduction in risk of SPB. Early prenatal enrollment and micronutrient use during the first trimester of pregnancy appeared to be of particular importance for prevention of SPB, regardless of supplement group.

One of the nation's health goals is to reduce the number of pregnant women who smoke, so that pregnant women are half as likely as nonpregnant women to smoke by 1990. To evaluate the progress toward this goal, the prevalence of smoking reported by 836 pregnant women was compared to that of 18025 nonpregnant women in 1985 and 1986. Pregnant women were 70 percent as likely to smoke cigarettes as nonpregnant women. Comparisons were also made with regard to race and marital status. Differences in smoking prevalence occurred because pregnant women were more likely to have stopped smoking rather than being more likely to have smoked at all. Also, unmarried pregnant white women were 40 percent more likely to smoke than single nonpregnant white women. Based on the findings, the national health goal seems unlikely to be achieved by 1990, and it is recommended that physicians spend more time counseling pregnant women who smoke to quit the habit.

Concerns have been raised about the benefits of Fe-containing supplements on infant birth weight among women with normal/high Hb levels at baseline. Thus far, no clinical trials have examined whether the effects of prenatal Fe-containing supplements on birth weight vary by maternal Hb levels. We compared the effects of Fe–folic acid (IFA) or multiple micronutrients (MMN) with folic acid (FA) supplements on birth weight among pregnant women with mild/no anaemia or high Hb levels. A double-blind randomised controlled trial was conducted in 2006–2009. In total, 18 775 pregnant women with mild/no anaemia (<100 g/l) were enrolled from five counties in north China. During the period from before 20 weeks of gestation to delivery, the women randomly received a daily supplement containing the following: (1) FA (400 μg); (2) IFA (FA, 400 μg; Fe, 30 mg); or (3) MMN (FA, Fe and thirteen additional vitamins and minerals). Birth weight was measured within the 1st hour of birth. Maternal Hb concentration was determined at enrolment. Among women with normal (≤132 g/l) or high (133–145 g/l) baseline Hb levels, IFA or MMN supplementation had no effect on birth weight. Among women with very high (>145 g/l) baseline Hb levels, IFA and MMN supplements increased birth weight by 91·44 (95 % CI 3·37, 179·51) g and 107·63 (95 % CI 21·98, 193·28) g (P<0·05), respectively, compared with the FA group. No differences were found between the IFA and the MMN group, regardless of maternal Hb concentration. In conclusion, the effects of Fe-containing supplements on birth weight depended on baseline Hb concentrations. The Fe-containing supplements improved birth weight in women with very high Hb levels before 20 weeks of gestation. [ABSTRACT FROM AUTHOR]
