Abstract Personal social networks (SN) affect health and wellbeing. This study used a multidimensional approach of \SN\ and social determinants of health (SDH) to examine the association between \SN\ and self-reported physical health among the aging population of Agincourt, South Africa. We analyzed the composition of personal \SN\ and used a multiple linear regression analysis to examine both network dimensions and \SDH\ that correlate with physical health. Results highlight the complexity and nuances of social relationships. A few recommendations were also made.
