Determinants of breastfeeding in a rural WIC population.

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.

Gestational age-specific birthweights of twins versus singletons.

In order to more adequately characterize patterns of intrauterine growth retardation in twins, the mean birthweights of all nonanomalous white or black twins born between 24 and 41 weeks of gestation and surviving until discharge over an 11-year period (547 infants) and all similar singletons (19,072 infants) were compared by completed weeks of gestation. Between 24 and 35 weeks of gestation, the mean birthweights for the 547 twins and the 19,072 singletons were comparable and did not consistently differ statistically. From 36 to 41 weeks gestation, however, the difference became large, consistent, and statistically significant for each week at P less than 0.0001. This difference was present among all subgroups of twins, ie, in all males, females, blacks, and whites; it was still evident when the sample was further stratified by both race and sex (black males, white males, black females, white females). These data suggest a pattern of growth retardation in twins compared to singletons which is large, consistent, and statistically significant beginning at 36 weeks gestation. Clinically, these data also suggest the need for ultrasonic examination early in gestation (24-32 weeks) to document normal growth and to provide baseline data, and show the importance of such monitoring later in gestation, specifically after 36 weeks.

Blood glucose rise after lactose tolerance testing in infants.

Lactose tolerance tests are used clinically to screen children and infants. It is assumed that absorption of a lactose challenge in infants would occur in a predictable pattern prior to weaning. Twenty-one infants from 3 to 12 months of age were studied. The maximum blood glucose rise over fasting levels ranged from 11.0 to 62.0 mg/100 ml; the mean was 32.6 mg/100 ml. Six infants had a maximum rise of less than 20 mg/100 ml. Eleven infants (52%) had a maximum rise of greater than 30 mg/100 ml. Signs of intolerance were not noted in any subject. Weight and length were normally disturbed. Results indicate the variance in glucose rise existing within a population of infants growing normally and consuming milk. Gastric emptying, digestion, and absorption may influence the blood glucose rise after a lactose test. Established glucose levels used as an index to lactose absorption in older children and adults may not accurately reflect lactase activity in infants.

Lactose malabsorption in preschool black children.

One hundred sixteen healthy black children ages 13 to 59 months, representing high and low socioeconomic deciles, were studied for lactose malabsorption. A fasting lactose tolerance test using 2 g of lactose/kg of body weight was carried out. Glucose was determined at 0, 15, 30, and 60 min. Of the 116 preschoolers 34 (29%) evidenced lactose malabsorption as determined by a blood glucose rise of less than 26 mg/100 ml. Clinical signs of diarrhea, gas, and cramps were noted singly or in combination in 18% of the 34 lactose-malabsorbing children. Of the 82 lactose absorbers, 12% demonstrated similar signs. The nature and length of the initial infant milk feeding failed to show any relationship to the onset of malabsorption. Current milk drinking patterns were reported as being similar. Eight-seven percent of the malabsorbers and 92% of the absorbers report drinking 240 ml or more of milk/day. Socioeconomic status, education, marital status, and medical assistance of the parent is similarly distributed between lactose absorbers and malabsorbers.

Relationship of milk consumption to blood glucose rise in lactose intolerant individuals.

Lactose intolerant populations are heterogeneous with respect to their milk-drinking habits. A gradation of lactase activity in the intolerant population may result in sufficient lactose hydrolysis to obviate symptoms and lead to continued milk consumption. This paper reports on differences in maximum blood sugar rise in lactose intolerant children who are observed to consume or reject milk. Of the 89 black elementary school children, 48 (54 per cent) evidenced a flat lactose tolerance curve. Twenty-eight of these 48 children (58 per cent) were defined as nonmilk drinkers. The maximum blood sugar rise was 12.3 mg/100 in the 20 lactose malabsorbers who were defined as milk drinkers. It appears that some lactose malabsorbing children may have sufficient, albeit lower, levels of lactase to hydrolyze moderate amounts of milk.

Lactose hydrolyzed milk.

Lactose intolerance is being reported in many populations. Yet, milk is highly nutritious and methods are being explored to use milk while limiting the lactose content. Thirty-two blacks 13-19 years of age were studied to determine a blood sugar rise with 8 ounces of the following test milks: 1) untreated whole milk (12 g/lactose); 2) 90% lactose hydrolyzed milk (1.2 g/lactose); and 3) 50% lactose hydrolyzed milk (6 g/lactose). In the 22 lactose malabsorbers, the peak blood sugars were: 1) untreated whole milk--4.4 mg/100 ml, 2) 90% lactose hydrolyzed milk--14.5 mg/100 ml, and 3) 50% lactose hydrolyzed milk--8.8 mg/100 ml. The 10 blacks with normal lactose absorption had a comparably high peak blood sugar on all three test milks. Differences between the blood sugar in the lactose absorbing and malabsorbing subjects when drinking untreated whole milk are significant (P less than 0.001); so are differences in the lactose malabsorbing subjects consuming untreated whole milk and 90% lactose hydrolyzed milk (P less than 0.001) as well as 50 and 90% lactose hydrolyzed milk. Symptoms were reported by three lactose malabsorbing subjects with untreated whole milk with two of the three symptomatic with 90% lactose hydrolyzed milk and none with 50% lactose hydrolyzed milk. No symptoms were reported by the lactose absorbers. Significant improvement in absorption with 90% lactose hydrolyzed milk is seen in low lactase subjects. Lactose hydrolyzed milk may serve as an important alternative for food planners wanting to provide milk to high risk populations with low lactase levels.

Intolerance of eight ounces of milk in healthy lactose-intolerant teen-agers.

The ability of lactose-intolerant individuals to tolerate 8 ounces of milk was determined in healthy teen-agers. Thirty-two blacks were studied with 50-gm lactose tolerance tests. Nineteen (59%) had a flat blood sugar curve and 13 (39%) also developed bloating, cramps, loose stools, or diarrhea with the test. These latter 13 were defined as lactose-intolerant. Seven of the 13 lactose-intolerant teen-agers (54%) developed abdominal bloating and/or cramps after drinking 8 ounces of milk (half-pint). None had diarrhea. Eight were symptomatic with the equivalent amount of lactose (12 gm) while only one had symptoms with the monosaccharide components of lactose, glucose and galactose. The symptoms with milk and 12 gm of lactose were less severe than with the 50-gm tolerance test. A history of a prior awareness of milk intolerance was obtained from 11 of the 13 lactose-intolerant subjects. At least one half of lactose intolerant teen-agers might be expected to be symptomatic after drinking 8 ounces of milk without other food. Milk intolerance should be considered in the nutritional planning for teen-agers with special attention to members of population groups with a high prevalence of lactose intolerance.

Current concepts in infant nutrition.

Nutritional needs vary during the first year of life according to the infant's individualized pattern of growth and amount of physical activity. After delivery, the infant must make many physiologic adjustments, develop immunologic defenses, and take in adequate nutrients for survival. The type and consistency of foods change as the gastrointestinal system matures and becomes able to metabolize the components and excrete the needed metabolites of increasingly complex foods. The recommended dietary allowance for infancy is based on the amount of nutrients provided to healthy infants in human milk during the first six months of life and on the consumption of formula and increasing amounts of solid food during the second six months. The introduction of solid foods should parallel the developmental changes that occur within the central nervous system throughout the first year; these provide a level of readiness for the infant to manage foods of various textures from full liquid to soft. Even though significant technologic advances have led to changes in the way infants can be fed, human milk is still the optimal choice. Most women can be encouraged to breast-feed regardless of their own nutritional status or dietary intake. Contraindications can be managed on an individual basis. If women do not elect to breast-feed, suitable commercial formulas are available. The important issue in feeding is that of providing a variety of appropriately prepared foods offered in a nonjudgmental atmosphere so that the foundation is laid for the development of good food habits.

Women intending to breastfeed: predictors of early infant feeding experiences.

We conducted interviews prenatally and postpartum with 187 women, all of whom intended to breastfeed their newborns. However, 18% of these women either never initiated breastfeeding or stopped within one week. Among women who initiated breastfeeding, we identified four variables as significant predictors of failure to breastfeed for more than seven days: lower confidence in ability to breastfeed, less certainty in the decision to breastfeed, delayed first breastfeeding experience, and lack of rooming in with the baby. Results of this study suggest that women at high risk for not implementing their prenatal breastfeeding intention can be identified for additional support; interventions should focus on prenatal confidence building, early and continuing contact with the newborn, anticipatory guidance prior to discharge, and early pediatric follow-up.
