Vitamin D deficiency is an important health risk for young women, particularly during their potential child-bearing years, and as many as 50% of Australian women are below optimal vitamin D levels.
Vitamin D deficiency has been linked with many chronic health conditions including poor bone and muscle health, heart disease, autoimmune diseases, infections, neurological diseases, cancer, diabetes and adverse mental health outcomes. Vitamin D deficiency in pregnancy is associated with adverse outcomes in the offspring. Major causes of vitamin D deficiency are decreased exposure to sunlight and low intake of dietary forms of vitamin D. We will obtain high-quality data on associations between vitamin D status and a broad range of health indices in young women. We propose also to conduct a randomised controlled trial (RCT) in a group of young women to compare the impact of: (1) a behavioural intervention using modern mobile technology to encourage safe levels of sunlight exposure, and (2) a pharmacological intervention to increase vitamin D levels.
The first part of this study (part A) involves recruitment of participants into a cross-sectional study in order to investigate the association of vitamin D (25-OHD) levels with clinical health indices and related laboratory measures: musculoskeletal health (bone density, bone turnover markers, muscle function); mood/mental health; body composition and weight; and atopic/allergic symptoms. This study will also allow us to identify participants with vitamin D levels of 25-75 nmol/L (expected to be 50% of the respondents), who will be invited to participate in part B of the study (RCT).
This project builds on our recent highly-successful Young Female Health Initiative (YFHI) pilot study and numerous other successful studies with young women.
