Vitamin D deficiency is a public health concern worldwide. Maintaining vitamin D sufficiency during growth periods is essential. We aimed to determine the prevalence and predictors of vitamin D deficiency in Australian adolescents and young adults.
To investigate the relationship between time spent outdoors, at particular ages in childhood and adolescence, and myopia status in young adulthood using serum 25-hydroxyvitamin D [25(OH)D] concentration as a biomarker of time spent outdoors. Participants of the Raine Study Generation 2 cohort had 25(OH)D concentrations measured at the 6-, 14-, 17- and 20-year follow-ups. Participants underwent cycloplegic autorefraction at age 20 years, and myopia was defined as a mean spherical equivalent -0.50 dioptres or more myopic. Logistic regression was used to analyse the association between risk of myopia at age 20 years and age-specific 25(OH)D concentrations. Linear mixed-effects models were used to analyse trajectory of 25(OH)D concentrations from 6 to 20 years.
Skin exposure to ultraviolet radiation alters the faecal microbiome, and further investigations to explore the implications of this in health and disease are warranted
Epidemiological evidence from the past decade suggests a role of vitamin D in food allergy pathogenesis
These data highlight that early life levels of vitamin D are an important consideration for maternal behavioural adaptations as well as offspring neuropsychiatry
The aim of this work is to review current metabolic and molecular aspects of the VitD-VitD receptor axis in reproductive medicine
The prevalence of vitamin D-containing supplement use was generally low in the Australian population, particularly for single vitamin D supplements
Associations between serum 25(OH)D concentrations and cardiometabolic risk factors from adolescence to young adulthood in the Raine Study
The strongest determinants of self-reported sun-protection behavior changes due to concerns about vitamin D were attitudes and location
UVB-induced p53-mediated cell cycle arrest and apoptosis are reduced in the presence of heat stress, leading to increased survival of DNA damaged cells
