This prospective study investigated the association between nutrient intake, dietary patterns, and changes in bone turnover and bone mineral density (BMD) in postmenopausal urban black South African women over two years. These women (n = 144) underwent BMD measurements at the distal radius, lumbar spine, femoral neck (FN), as well as a biochemical analysis which included the parathyroid hormone (PTH), 25-hydroxyvitamin D, C-Telopeptide of type I collagen (CTX-1) in 2010 and 2012. Their dietary i...

The ergogenic effect of caffeine on endurance exercise is commonly accepted. We aimed to elucidate realistically the effect of caffeine on triathlon event performance using a field study design, wh...
The rising prevalence of obesity and excessive adiposity are global public health concerns. Understanding determinants of changes in adiposity over time is critical for informing effective evidence-based prevention or treatment. However, limited information is available to achieve this objective. Cultural, demographic, environmental, and behavioral factors including socio-economic status (SES) likely account for obesity development. To this end, we related these variables to anthropometric measu...
The relationship between 25 hydroxyvitamin D (25(OH)D), parathyroid hormone (PTH) and metabolic traits appear to differ among ethnicities and may be influenced by obesity. The aim of the study was to examine the association of serum 25(OH)D or PTH with metabolic syndrome (MetS) while controlling for adiposity in black women. Using a cross-sectional study design, 209 urban black women aged ≥ 43 years from the North West Province, South Africa, were included. Multiple regression models were used t...
Endurance athletes recognize that a leaner and lighter body can improve performance outcomes. Currently, there is limited data assessing disordered eating, including orthorexia nervosa, in endurance athletes choosing to adhere to GWDs. Purpose: The aim of this study was to assess disordered eating, including orthorexia behaviors, in endurance athletes following GWDs compared to athletes following a normal diet (ND). Methods: Endurance athletes (ages 18-55y) were invited to participate in a web-b...
South African studies indicated that urban Black and White women have similar bone turnover. However, urban Black women had low bone mass and greater exposure to lifestyle risk factors for bone disease. The purpose of this prospective study was to assess changes in bone turnover, parathyroid hormone (PTH) levels, bone health (forearm, hip and lumbar spine bone mineral density) in urban black South African women over 3 years. Black, urban postmenopausal women (n=144, >50 years) from the North-Wes...
Introduction: The relationship between 25 hydroxyvitamin D (25(OH)D), parathyroid hormone (PTH) and metabolic traits appear to differ among ethnicities and may be infl uenced by excess adiposity. Aim: To examine the association of serum 25(OH)D and PTH, respectively, with the metabolic syndrome (MetS) while controlling for adiposity in black women. Methods: A cross-sectional study was carried out among 209 urban black women aged ≥ 43 years from the North West Province, South Africa. The relation...
Background: Modern culture has stereotyped the female body as one that is continually getting thinner. Internalization of the ‘thin’ ideal is partly attributable to the inner ideal to be successful combined with the external pressure imposed by media and others. Many individuals attempt to achieve these ideals by behavior modification that imposes health risks. Purpose: To investigate disordered eating (DE) behavior and energy status in female student dancers. Methods: Volunteer dancers (n = 26)...
BACKGROUND/OBJECTIVES: Age-related muscle and fat mass (FM) changes are ethnicity specific. We aimed to develop a cut-point for the muscle mass component of sarcopenia for black South African (SA) women, and to assess its predictive value, in comparison to established cut-points, to identify functional ability among older black SA women. SUBJECTS/METHODS: In a cross-sectional study, a sarcopenia cut-point was calculated from dual energy X-ray absorptiometry (DXA)-derived appendicular skeletal mu...
