BACKGROUND Optimal nutrition for lactating mothers is importance for mother and infants' health and well-being. We determined the nutrient intake and dietary changes during the first 3-month of lactation, and its potential effect on health and disease risk. METHOD Personal interviews were conducted to collect a 24 h diet recall questionnaire from 199 healthy lactating women in the postpartum ...

OBJECTIVE Lactating women and their infants are susceptible to iodine deficiency and iodine excess. In South Africa, no data exist on the iodine status and thyroid function of these vulnerable groups. METHODS In a cross-sectional study, urinary iodine concentrations (UIC), thyroid function, and breast-milk iodine concentrations (BMIC) were assessed in 100 lactating women from a South African ...

Pituitary and ovarian function at the end of pregnancy and during the first six weeks after delivery was investigated serially in women who fully breast-fed their infants and in women who did not. In the women who did not breast-feed the plasma prolactin level decreased rapidly and from the third day after delivery was significantly lower than in the breast-feeding mothers, reaching the normal ...

OBJECTIVE To assess vitamin E levels in the breast milk, analyzing the prematurity and the birth weight influence in α-tocopherol concentration of colostrum milk. METHODS Cross-sectional study, in which the colostrum was collected from 93 nursing mothers in a public maternity of Natal, Rio Grande do Norte, Northeast Brazil. The newborns were classified based on gestational age and birth weigh...

Pulmonary tumors were induced in mice that were suckled by mothers that received urethan during lactation. More induced tumors appeared in sucklings when urethan was injected into lactating mothers soon after delivery. When pregnant mice were treated with urethan during gestation and lactation their offspring had a significantly increased incidence of pulmonary tumors, and the number of tumors ...

Breast milk is the ideal food for infants and should be consumed as the exclusive food for the first six months and then be complemented up to two years of age. The aim of this study is to determine breast milk’s content of macro and micronutrient in lactating mothers from the Ribeirão Preto (SP) region, in Brazil. A cross-sectional study was conducted with breast milk samples of 70 mothers fro...

BACKGROUND Infants are very sensitive to iodine deficiency. Breastfed infants are dependent on maternal iodine intake. The aim of this study was to evaluate the relationship between maternal iodine status during lactation and infant weight and length. METHODS A cross-sectional survey was conducted to investigate maternal iodine status and infant anthropometric measures in Henan Province, Chin...

OBJECTIVES To compare the effects of a human breastmilk-derived fortifier on the antibacterial activity of milk obtained from lactating mothers delivering prematurely with the effects of a powdered fortifier on the same milk. STUDY DESIGN Human milk samples were obtained after the first week of postnatal life from 10 lactating mothers, who had delivered prematurely. A bovine milk-based powder...

Lactating rats exhibit stable individual differences in pup licking/grooming. We used in vivo voltammetry to monitor changes in extracellular dopamine (DA) in the nucleus accumbens (n. Acc) shell of lactating rats interacting with pups and found that (1) the DA signal increased significantly with pup licking/grooming; (2) the onset of such increases preceded pup licking/grooming; and (3) the ma...

The purpose of the present study was to compare which parts of the body fat mass tended to increase during the third trimester and at 1 month postpartum between lactating and nonlactating Japanese women. This prospective study examined 49 healthy pregnant women in the third trimester, and at 1 month postpartum. Demographic data, including lactation status, were obtained from a self-administered...
