Aim
. To measure the association between infant feeding practices and parent-reported nut allergy in school entrant children.
Method
. The Kindergarten Health Check Questionnaire was delivered to all 110 Australian Capital Territory (ACT) primary schools between 2006 and 2009. Retrospective analyses were undertaken of the data collected from the kindergarten population.
Results
. Of 15142 children a strong allergic reaction to peanuts and other nuts was reported in 487 (3.2%) and 307 (3.9%), children, respectively. There was a positive association between parent reported nut allergy and breast feeding (OR = 1.53; 1.11–2.11) and having a regular general practitioner (GP) (OR = 1.42; 1.05–1.92). A protective effect was found in children who were fed foods other than breast milk in the first six months (OR = 0.71; 0.60–0.84).
Conclusion
. Children were at an increased risk of developing a parent-reported nut allergy if they were breast fed in the first six months of life.
Rising rates of caesarean section (CS) have been attributed, in part, to maternal-choice CS (MCCS). There are few published data regarding maternal and perinatal risks comparing MCCS with planned vaginal birth (VB) in uncomplicated first pregnancies to inform choice. We report the results of a pragmatic patient-preference cohort study of private patients in Australia: 64 women planning MCCS and 113 women planning VB. There were few differences in outcome between the two groups. The study highlighted the well-recognised difficulties in undertaking prospective research into MCCS.
Background: There is variation in uptake of in vitro fertilisation (IVF) between countries, and Australia has high incidence rates of IVF due to universal public funding. However, it remains unclear whether there is regional variation and, if present, what might cause this.
Objectives: We sought to determine whether regional variations in treatment rates existed and what might influence these.
Methods: The number of cycles of fresh IVF and intrauterine insemination (IUI) for women were obtained for the period 2011 until 2014 in two age groups (25 to 34 years and 35 to 44 years) to calculate incidence rates. Proxy indicators that might influence treatment affordability were: unemployment rates; average weekly total earnings; coverage of private health insurance; and, percentage of women in the highest socioeconomic quintile. Measures of accessibility considered were percentage of the population remote from urban areas and average state population density. Linear regressions were performed using log-transformed ratio of IVF and IUI incidence rates.
Results: Variations were found in IVF uptake between states with greater differences in older women. There was no significant association between IVF procedures and population density or geographic isolation. Economic factors were not associated with IVF uptake.
Conclusion: These findings suggest that factors such as physician preference, clinical practice guidelines, and cryopreservation protocols of ART units might explain the national variation in uptake of IVF.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
