The transfer of alcohol to human milk. Effects on flavor and the infant's behavior.
(65/161)
BACKGROUND: The amount of alcohol ingested by a breast-fed infant is only a small fraction of that consumed by its mother, but even this small amount may have an effect on the infant. We investigated whether the ingestion of alcohol by a lactating woman altered the odor of her milk and whether exposure to a small amount of alcohol in the mother's milk had immediate effects on the behavior of the infant. METHODS: Twelve lactating women and their infants were tested on two days separated by an interval of one week. On each testing day, the mother expressed a small quantity of breast milk and then drank either orange juice or orange juice containing a small quantity of ethanol (0.3 g per kilogram of body weight). Additional milk samples were obtained at fixed intervals after the ingestion of the beverage and analyzed to determine their ethanol content. The samples were also evaluated by a panel of adults to determine whether any difference in the odor of the milk was detectable after alcohol ingestion. The infants were weighed before and after nursing to assess the amount of milk they ingested, and their behavior during breast-feeding was monitored by videotape. RESULTS: Short-term alcohol consumption by lactating women significantly and uniformly increased the perceived intensity of the odor of their milk as assessed by the panel; this increase in the intensity of the odor peaked 30 minutes to 1 hour after the alcohol was consumed and decreased thereafter. The alteration in the odor of the milk closely paralleled the changes in the concentration of ethanol in the milk (mean range, 0 to 6.9 mmol per liter [0 to 32 mg per deciliter]). The infants sucked more frequently during the first minute of feedings after their mothers had consumed alcohol (67.0 +/- 6.5 sucks, as compared with 58.4 +/- 5.9 sucks for feedings after the consumption of the nonalcoholic beverage; P less than 0.05), but they consumed significantly less milk (120.4 +/- 9.5 ml vs. 156.4 +/- 8.2 ml, P less than 0.001) during the testing sessions in which their mothers drank the alcoholic beverage. CONCLUSIONS: Although the mechanisms underlying this reduction in milk intake remain to be elucidated, this study shows that short-term alcohol consumption by nursing mothers has an immediate effect on the sensory characteristics (odor) of their milk and the feeding behavior of their infants.

Association between breast-feeding practices and sucking habits: a cross-sectional study of children in their first year of life.
(66/161)
In addition to providing nutrition and immunological protection, breast-feeding has positive effects on the development of the infant's oral cavity. The aim of the present study is to assess breast-feeding patterns and to analyze the influence of breast-feeding practices and maternal sociodemographic variables on the prevalence of non-nutritive sucking habits in a sample of Brazilian infants. This cross-sectional study was carried out in Southern Brazil. A random sample of 100 mothers of infants up to 12 months of age was interviewed during the National Vaccination Campaign Day. The prevalence and median duration of breast-feeding were assessed. Breast-feeding practice, the exposure factor, was categorized as exclusive breast-feeding, predominant breast-feeding, complementary breast-feeding, or weaning. Maternal sociodemographic variables included age, race, marital status, educational level, profession, and family income. The outcome investigated was the prevalence of sucking habits (pacifier use and thumb sucking). We used two-sample tests, the chi-square test and FISHER'S EXACT TEST for statistical analyses of the data. The study revealed that 75% of infants were being breast-fed. Pacifier use and thumb sucking were common in 55%. Bottle-feeding was prevalent in 74% of infants. Breast-feeding was negatively correlated with pacifier use and thumb sucking (OR=0.11; 95% CI: 0.03 to 0.4). Bottle-feeding was strongly associated with weaning (p=0.0003). Among the sociodemographic variables, only marital status showed a statistical association with sucking habits (p=0.04). These findings suggest that breast-feeding can prevent the occurrence of sucking habits. Although we could not evaluate causality assessment, malocclusion prevention seems to be yet one more reason for promoting breast-feeding practices. (+info)

Sucking on the 'emptied' breast: non-nutritive sucking with a difference.
(70/161)
A simple method to promote the use of human milk and subsequent breast feeding in low birthweight infants was evaluated in 32 babies. In the 'intervention' group (n = 16; mean (SD) weight 1559 (228) g and length of gestation 33.2 (1.8) weeks), infants were allowed to suckle at the breast when their general condition permitted after as much milk as possible had been expressed, and were then given the full required feeds by tube. Full breast feeding was started as soon as the infant could suck adequately. Sixteen control infants (mean (SD) weight 1605 (198) g and length of gestation 34.1 (2.4) weeks), were breast fed in the conventional manner only after it had been established that they could suck well; until then they received all their feeds by tube. After discharge the mean (SD) periods of exclusive and total breast feeding were longer in the group that had received the intervention (3.7 (1.3) and 5.1 (2.2) months, respectively) than among the controls (1.9 (0.6) and 3.3 (1.9) months, respectively). This 'intervention' method helps to promote milk formation, provides sucking experience for low birthweight infants without interfering with their nutritional intake and consequent weight gain, and encourages subsequent breast feeding with its well recognised advantages.
