The Effects Of Vitamin D Supplementation On Athletic Performance And Injury Prevention, Amani Adeeb Abushamma

Journal of Sports Medicine and Allied Health Sciences: Official Journal of the Ohio Athletic Trainers Association

Vitamin D supplementation has numerous effects on athletic performance and plays a significant role in preventing an athlete’s risk of getting injuries. Vitamin D has an impact on numerous physiological functions such as: bone health, muscle function, inflammatory response, and immune function. An athlete’s bone and muscle health are essential for maximum performance and career success. A bone fracture due to vitamin D deficiency can delay an athlete’s training and ultimately inhibit obtaining a collegiate scholarship and/or contract. A cross sectional study found that more than half of athletic trainers did not view 25-hydroxyvitamin D(25[OH]) testing and vitamin D supplementation …

Woman and Child Health

Nutritional deficiencies are a leading underlying risk factor contributing to the global burden of disease. In Pakistan, late adolescence is considered a nutritionally vulnerable period, as micronutrient requirements are increased to support maturation, and dietary staples are nutrient poor. However, there has been limited evaluation of micronutrient status beyond anemia and its determinants. Using cross-sectional data from late adolescent and young women (15-23 years) at enrolment in the Matiari emPowerment and Preconception Supplementation (MaPPS) Trial, we aimed to describe the prevalence of key micronutrient deficiencies of public health concern, and generate hierarchical models to examine associations with proxies for social …

Department of Pathology and Laboratory Medicine

This study was conducted to determine the association between place of residence (grouped into neighbourhoods), and 25-hydroxy D (25[OH]D) levels of individuals of Karachi. Addresses of 4788 individuals tested for 25[OH]D at the clinical laboratory of the Aga Khan University (AKU), Karachi, from January 2007 to June 2008 were reviewed. The neighbourhoods were categorized into ten, based on locality attributes. A high overall prevalence (74%) of vitamin D deficiency (VDD) was observed. There was a significant difference (p-value < 0.01) between mean log 25[OH]D levels amongst neighbourhoods grouped according to distinct housing structure attributes and localities. A high frequency of VDD in all the studied localities of an urban city warrant dietary vitamin D supplementation and food fortification.
