Breastfeeding: Nature's Safety Net

Infant and young child feeding patterns in Kuwait: results of a cross-sectional survey

OBJECTIVE

The beneficial role of breast-feeding for maternal and child health is now well established. Its possible role in helping to prevent diabetes and obesity in children in later life means that more attention must be given to understanding how patterns of infant feeding are changing. The present study describes breast-feeding profiles and associated factors in Kuwait. Design/Setting/Subjects Interviews with 1484 recent mothers were undertaken at immunisation clinics across Kuwait. Descriptive analysis and binary logistic regression of results were performed.

RESULTS

Rates of breast-feeding initiation in Kuwait were high (98·1 %) but by the time of discharge from hospital, only 36·5 % of mothers were fully breast-feeding, 37·0 % were partially breast-feeding and 26·5 % were already fully formula-feeding. Multiple social and health reasons were given for weaning the child, with 87·6 % of mothers who had stopped breast-feeding completely doing so within 3 months postpartum. Nationality (P<0·001), employment status 6 months prior to delivery (P<0·001), mode of delivery (P=0·01), sex of the child (P=0·026) and breast-feeding information given by nurses (P=0·026) were all found to be significantly associated with breast-feeding. Few women (5·6 %) got information on infant nutrition and feeding from nursing staff, but those who did were 2·54 times more likely to be still breast-feeding at discharge from hospital. Over 70 % of mothers had enjoyed breast-feeding and 74 % said they would be very likely to breast-feed again.

CONCLUSIONS

In Kuwait where the prevalence of both obesity and type 2 diabetes is growing rapidly, the public health role of breast-feeding must be recognised and acted upon more than it has in the past.

Efficient Fluorescence Detection of Aromatic Toxicants and Toxicant Metabolites in Human Breast Milk

Once chemical contaminants are released into the environment, there are a number of concerns that arise regarding the environmental persistence of the contaminants, their known and suspected toxicities, and their potential disruption to the ecosystem. One class of contaminants that is of continuing concern is polycyclic aromatic hydrocarbons (PAHs), persistent organic pollutants that are significant components of oil spills. PAHs have been found in the breast milk of nursing mothers living in oil spill affected regions, and can harm the nursing children. We report herein the sensitive and selective detection of 10 PAHs and PAH metabolites in human breast milk using fluorescence energy transfer from the PAH to a high quantum yield fluorophore, and array-based statistical analyses of the resulting fluorescence responses. This detection system was able to separate and identify the PAHs with 100% success in human breast milk and at concentrations as low as 0.17 μM. These results have significant implications in public health and in the monitoring and mitigation of environmental disasters.

Association of breastfeeding and three-dimensional dental arch relationships in primary dentition

BACKGROUND

The benefits of breastfeeding on oral health are still inconclusive, especially the association on occlusion. This study aimed to investigate the association of breastfeeding and the development of primary dentition.

METHODS

A cross-sectional study was conducted with 851 Asian children aged 2-5 years old in Hong Kong. Questionnaires were completed by the parents to collect information on breastfeeding and the non-nutritive sucking habits. The children's dental arch relationships were examined in the sagittal, vertical, and transverse dimensions by an experienced examiner.

RESULTS

Children who experienced pure breastfeeding for more than 6 months had a lower chance of developing a class II incisal relationship (P < 0.05) or an increased overjet (P < 0.05), and had wider intercanine (P < 0.05) and intermolar widths (P < 0.05). Vertically, no association on the extent of overbite or openbite was found (P > 0.05).

CONCLUSIONS

Pure breastfeeding for more than 6 months is positively associated with primary dental arch development in the anterior sagittal dental segment and on the horizontal arch width in primary dentition. Therefore, pure breastfeeding for more than 6 months is recommended, as it is associated with lower chance of the development of abnormal dental relationships. The results will be valuable for education and promotion of maternal breastfeeding.
