Background: Studies have shown that a proportion of children as young as two years are already overweight. This indicates that obesity prevention programs that commence as early as possible and are family-focused are needed. This Healthy Beginnings Trial aims to determine the efficacy of a communitybased randomized controlled trial (RCT) of a home visiting intervention in preventing the early onset of childhood overweight and obesity. The intervention will be conducted over the first two years of life to increase healthy feeding behaviours and physical activity, decrease physical inactivity, enhance parent-child interaction, and hence reduce overweight and obesity among children at 2 and 5 years of age in the most socially and economically disadvantaged areas of Sydney, Australia.
BackgroundIn 2001, the World Health Organisation (WHO) recommended exclusive breastfeeding for the first six months of life. The objectives of this study are to assess awareness of the WHO recommendation among first-time mothers (women at 24 to 34 weeks of pregnancy) and to explore the relationship between this awareness and mothers' intention to exclusively breastfeed for six months.MethodsThis study was part of the Healthy Beginnings Trial (HBT) conducted in southwest Sydney, Australia. We analysed cross-sectional baseline data of the trial conducted in 2008, including 409 first-time mothers at 24 to 34 weeks of pregnancy. The mothers' awareness of the recommended duration of exclusive breastfeeding and their intention to meet the recommendation were assessed through face-to-face interviews. Socio-demographic data were also collected. Factors associated with awareness of the recommendation, or the intention to meet the recommendation, were determined by logistic regression modeling. Log-binomial regression was used to calculate adjusted risk ratios (ARR).ResultsSixty-one per cent of mothers knew the WHO recommendation of exclusive breastfeeding for six months. Only 42% of all mothers intended to meet the recommendation (breastfeed exclusively for six months). Among the mothers who knew the recommendation, 61% intended to meet the recommendation, compared to only 11% among those mothers who were not aware of the recommendation.The only factor associated with awareness of the recommendation was mother's level of education. Mothers who had a tertiary education were 1.5 times more likely to be aware of the recommendation than those who had school certificate or less (ARR adjusted for age 1.45, 95% CI 1.08, 1.94, p = 0.02). Mothers who were aware of the recommendation were 5.6 times more likely to intend to breastfeed exclusively to six months (ARR adjusted for employment status 5.61, 95% CI 3.53, 8.90, p < 0.001).ConclusionAwareness of the recommendation to breastfeed exclusively for six months is independently associated with the intention to meet this recommendation. A substantial number of mothers were not aware of the recommendation, particularly among those with low levels of education, which is of concern in relation to promoting breastfeeding. Improving mothers' awareness of the recommendation could lead to increased maternal intention to exclusively breastfeed for six months. However, whether this intention could be transferred into practice remains to be tested.Trial RegistrationHBT is registered with the Australian Clinical Trial Registry (ACTRNO12607000168459)
Abstract:The purpose of this study was to determine the iron status of preschool children in Sydney. We assessed 678 children aged 9 to 62 months living in 32 randomly selected census collection districts in central and southern Sydney for iron status using plasma ferritin; of these 678 children, 542 had zinc protoporphyrin tests, red cell indices and haemoglobin tests. Risk factors for iron deficiency were assessed by an administered questionnaire. Overall, the prevalence of iron depletion was 10.5 per cent, iron deficiency 2.8 per cent and iron deficiency anaemia 1.1 per cent. The 24to-35-month age group (176 children) had the highest prevalence of iron deficiency anaemia of 3.0 per cent, although iron depletion (18.7 per cent) and iron deficiency (5.4 per cent) were highest among the 9-to-23-month age group (182 children). Low iron status was related to age of under 24 months (odds ratio (OR) 2.86, 95 per cent confidence interval (CI) 1.72 to 4.76). After adjustment for this age effect, the consumption of red meat fewer than four times a week was significantly associated with iron depletion (OR 2.27, CI 1.25 to 4.17) and there was a tendency for children who were being given a vitamin supplement to be less likely to be iron depleted (OR 4.00, CI 0.95 to 16.67). Iron deficiency and iron deficiency anaemia do not represent a major public health problem in preschool children in Sydney. However, for children in the age range of 12 to 36 months there is scope for interventions to further reduce the prevalence of iron deficiency anaemia.
We reviewed the outpatient medical records of 265 homeless children less than 5 years of age in New York City and compared them with children of similar low socioeconomic status (SES) attending the same pediatric clinic. The frequency of health problems among the homeless children, including delayed immunizations, elevated blood lead levels, the rate of admission to hospital, and the rate of child abuse and neglect reports, exceeded those for the comparison groups.

multiple birth. Familial occurrences of dizygotic twinning found in this and other epidemiological studies are at least in part due to genetic factors.The risk of twin births to monozygotic mothers was not significantly increased, but monozygotic mothers had significantly more same sex twin births. Comparison of estimated and expected numbers of monozygotic twin births suggests that this increase is a result of monozygotic twinning. Although other studies have suggested a familial component in monozygotic twinning, samples have been small and the methods susceptible to recall bias.46This population based study shows that women who are twins have an increased risk of giving birth to twins. Contrary to results based on self reports,4 this registry based study, free from recall bias, does not support the existence of a common aetiology for monozygotic and dizygotic twinning.
