The objective of the study is to describe how design thinking as a participatory process can be applied in determining how sustainable physical activity and nutrition interventions should be implemented in a low resourced community in South Africa. Physical inactivity is the 4th leading cause of mortality world-wide. Associated with inactivity, a high prevalence of obesity is reported. Evidence based research indicate that sustainable physical activity and nutrition interventions will reduce the...

Background: Sarcopenia, the loss of muscle mass and strength, is associated with adverse health outcomes. Calf circumference (CC) has been proposed as a surrogate measure of muscle mass in the elderly; however, ethnic/sex specific cut-off values remain to be established.Objective: A study was undertaken to investigate the relationship between CC and appendicular skeletal muscle mass (ASM), and the ASM index (ASMI), as well as to determine whether CC could be used to diagnose sarcopenia.Methods: ...

Objectives To derive percentage body fat (%BF) cut-points according to body mass index (BMI) categories for adult black South African women and to investigate the agreement between adiposity classifications according to WHO BMI and %BF cut-points. The secondary aim was to determine the association between these different adiposity measures and high blood pressure. Methods Black women aged 29–65 years (n = 435) from Ikageng, South Africa, were included in this cross-sectional study. Socio-demogra...

Methods: This paper addresses my experiences in developing and implementing technology in health science classrooms in a setting not adequately equipped to do so. Results: After reflecting on my experiences, I conclude that it is ...

Flipping classrooms from traditional teaching approaches to technology-enhanced interactive classrooms requires that previously designed software be revisited for mobile use. This paper: (i) describes how an existing custom-made test-and-quiz multimedia application, originally created in Articulate Storyline™, was re-designed for Adobe Flash™ to encapsulate the original functionality for use on an array of mobile devices; and (ii) qualitatively evaluates students’ perceptions of the value of the...
