METHODS: Perinatal data have been routinely recorded in Northern Ireland for all births in the period 1971-86 (n = 447 663). Diabetes status at the age of 15 years was ascertained in this cohort by identifying 991 children from 1079 registered with Type 1 diabetes diagnosed from 1971 to 2001 and date of birth in the period 1971-86. RESULTS: Increased Type 1 diabetes risk was associated with higher maternal age, paternal age, birth weight and birth weight for gestational and lower gestational age. After adjustment for maternal age, the association between Type 1 diabetes and paternal age remained significant [relative risk (RR) = 1.52 (1.10, 2.09) comparing father's age 35 years or more to less than 25 years] but not vice versa [RR = 1.11 (0.80, 1.54) comparing mother's age 35 years or more to less than 25 years]. Increased birth order was associated with a significant decrease in the risk of Type 1 diabetes [adjusted RR = 0.75 (0.62, 0.90) comparing birth order three or more with firstborn], but this only became apparent when adjustment was made for maternal age. Furthermore this association with birth order was significant only for diabetes diagnosed under the age of 5 years. CONCLUSIONS: Our analysis demonstrates, for the first time in a UK regional cohort setting, that maternal age and paternal age at delivery, birth order, birth weight and gestational age are significantly associated with Type 1 diabetes risk.PMID: 15660739 [PubMed - indexed for MEDLINE]

LinksRisk factors for type I diabetes mellitus in children in Austria.Rami B, Schneider U, Imhof A, Waldhör T, Schober E.University Children's Hospital Vienna, Austria.The aim of this study was to investigate environmental risk factors in the development of type 1 diabetes mellitus in a population-based case-control study. Parents of all patients with manifestation of type 1 diabetes between 1989 and 1994 in Vienna were asked to complete a questionnaire (n = 114). Control children (n = 495), matched for age and sex, were randomly recruited from all schools in Vienna. Fathers of diabetic children were significantly older at the time their children were born than fathers of control children (P = 0.015). Children with diabetes were more likely to be second- or third-born children (P<0.05) p =" 0.007)." p =" 0.038)." color="#cc0000">In our study, the development of type 1 diabetes mellitus was associated with higher paternal age and neonatal jaundice. No correlation could be found with dietary intake of cow's milk products in early infancy, vaccination and other environmental factors. Labels: the mystery of the rise in type 1 diabetes is solved

The corporate filter at this point in time mandates that news sources only report what best serves conservative agendas (the "liberal media" accusation is no match for this filter). You'd think that this study would be important to republican propaganda, as reducing the financial tolls on society would be a big plus. The problem with that assumption is that the conservative agenda is inextricably laced with a patriarchally constructed value system. Guess which of the following studies were splashed across the news:1. Children in daycare do poorly later in life compared to children with stay-at-home moms.vs.2. Outcomes for children more positive as father's time spent at home increases.One was hyped and the other not even reported by mainstream news outlets. Why do you think that is?The problem with studies about advanced paternal age is that it knocks men off their self-made pedestal of privilege in regard to mate choice and the myths they propagate about biology being conflated with women necessarily lacking certain political/economic/personal rights and privileges. The power automatically afforded to men in virtually every sphere--personal, economic, political, social--doubles under a patriarchal system. Of course they don't want to give that up! Advanced paternal age studies have been around since the 1800s--long before maternal risk of Down Syndrome after age 35 was established, I'm sure. The problem with the paternal age information is that it empowers women in a way that is notsogewd for most men already in the throes of adulthood. And that's not just because many will lose value in the mate market, but mainly because it disrupts their entire artificially fabricated world view that supports their privilege in every other facet of life.-K.A.
