The rise in smoking rates among young women has implications for children's health aggravated in lower social strata where infant morbidity and mortality rates are higher. The protection afforded by breastfeeding is beneficial to infants in rich and poor countries alike. Women (especially when young, uneducated, and unsupported) who are smokers constitute a risk group for abandoning breastfeeding; moreover, their bottle-fed newborns run a greater risk of morbidity and mortality. Bottle-feeding is attendant on maternal cigarette smoking. The advantages of breastfeeding over bottle-feeding are discussed with regard to systemic effects and the specific effects of cyanide (which can affect the iodine metabolism of infants) and nicotine derived from food and maternal smoking. Despite great strides in bans on smoking, public health policies should be designed to keep in perspective that breastfeeding is an effective tool to counterbalance the health disadvantages that under-privileged infants of smoking mothers face. This paper argues that infants born to smoking parents are better protected by breastfeeding than by formula feeding. Therefore, if public health policies cannot stop addicted mothers from smoking during pregnancy it is fundamental not to miss the chance of encouraging and supporting breastfeeding. The food and health inequalities of socially disadvantaged groups demand well crafted public-health policies to reduce the incidence of diseases and compress morbidity: these policies need to make it clear that breastfeeding is better and safer.
OBJECTIVE: Little is known about the effects of social and biological risk factors for open bite on the primary dentition. The aim of this study was to assess the early-life risk factors affecting anterior open bite. METHODS: A cross-sectional study using a birth cohort was carried out in Pelotas, Brazil. A sample of 400, 6-year-old children was employed. The Foster and Hamilton criteria were used to classify open bite. Data concerning social conditions, and perinatal and childhood health and behaviour were obtained from birth to 12 months of age and during the fifth year of the children's lives. Unconditional bivariate and multiple logistic regression analysis were performed. RESULTS: The prevalence of anterior open bite was 46.3%. Risk factors included: a maternal age of between 30 and 39 years, as compared with children whose mothers were younger; breast-feeding for < 9 months; dental caries experience; pacifier sucking between 12 months and 5 years, as compared to no sucking or a shorter duration of sucking; and the presence of finger-sucking at 6 years of age. CONCLUSION: Open bite in the primary dentition was associated with older mothers, early weaning, dental caries occurrence, long-term use of a pacifier and finger-sucking at 6 years of age. These findings support the common risk approach for intervention to prevent open bite in the primary dentition.
The chemokine RANTES (regulated upon activation, normal T cell expressed and secreted) plays a significant role in the innate immunity, which is particularly important in the neonatal period. In this study, we aimed to investigate the ability of the neonate to increase plasma levels of RANTES in the first month of life, and the possible impact of breast feeding on this ability. The study population consisted of 125 healthy term neonates that were exclusively breast-fed (n = 62) or formula-fed (n = 63) for at least 1 month after birth. Plasma RANTES concentrations (ELISA) as well as circulating leukocytes and platelets were measured on days 1 and 30 of life. Median RANTES concentrations of the total group showed a significant increase between day 1 [1000 (448-2100) pg/mL] and day 30 [3688 (1488-5400) pg/mL, p < 0.0001], as did median total lymphocyte, T-cell, B-cell, NK-cell and eosinophil counts (all p values <0.0001). Monocyte and platelet counts did not change significantly over the neonatal period. Further analysis according to the mode of feeding showed that RANTES levels as well as leukocyte populations and platelet counts did not differ significantly between breast-fed and formula-fed neonates on either day 1 or 30. Healthy term neonates are capable of increasing plasma RANTES levels during the 1st month after birth independently of the mode of feeding.
