Vitamin D deficiency is common among otherwise healthy pregnant women and may have consequences for them as well as the early development and long-term health of their children. The importance of maternal and neonatal vitamin D status on later health has not been widely studied. The D-tect is a project financed by the Danish Council for Strategic research, comprising a battery of observational studies on associations between exposure to/status of vitamin D early in life and risk of various diseases later in life. All the studies use data from the Danish National registers. The fact that mandatory fortification of margarine with vitamin D in Denmark was cancelled in 1985, and thus, children born before and after 1985 differed by prenatal exposure to extra vitamin D, is utilized. Additionally, neonatal vitamin D status is measured using dried blood spots (PKU cards) kept in the The Danish Newborn Screening Biobank.
Diets have been proven effective in relation to short term weight loss. However, programmes that tries to help people maintain a weight loss in the longer-term show high relapse and attrition rates, rendering them overall ineffective. Thus, the NoHoW intervention will evaluate the effectiveness of evidence-based ICT behaviour change tools for weight loss maintenance after a clinically significant weight loss.
