Perceived neighborhood safety and exercise behavior among community dwellers in Gauteng, South Africa

Maintaining a physically active life is an important determinant of overall health and psychosocial wellbeing among adults. Physical exercise behavior can be influenced by various social and environmental circumstances including neighborhood safety. Using data from South Africa Quality of life Survey 2015/16, this study aimed to assess the hypothesis that lack of perceived neighborhood safety (PNS) can reduce the likelihood of engaging in physical exercise (PE). The participants were 30,002 men and women aged 18 years and above. The association between self-reported PE behavior and neighborhood safety were assessed by multivariable regression method while adjusting for potentially confounding factors. Less than a quarter (23.41%) of the participants reported taking exercise on daily basis whereas 27.90% reported never taking any. Respectively 6.0% and 38.1% of the participants reported feeling very unsafe walking in the neighborhood during day and night. In regression analysis, both the pooled and stratified models indicated that lack of PNS was inversely associated with regular PE. Lack of PNS (bit unsafe) during day was associated with lower odds of PE both among men (OR = 0.776, P < .001) and women (OR = 0.874, P < .001). The negative association between lack of PNS and PE during day was significant among those living with disability (OR = 0.758, P < .001). Further analysis showed that the negative association between lack of PNS with regular PE during day was significant in Johannesburg (OR = 0.800, P < .001), Tshwane (OR = 0.735, P < .001) and Emfuleni (OR = 0.619, P < .001) only, while that during night was significant in Johannesburg (OR = 0.737, P < .001), Ekurhuleni (OR = 0.673, P < .001), Emfuleni (OR = 0.418, P < .001), Lesedi (OR = 0.385, P < .001), Mogale City (OR = 0.693, P < .001), and Randfontein (OR = 0.565, P < .001). Overall, the findings highlight a significantly inverse association between lack of PNS and PE behavior. In light of the current findings, it is recommended that PE promotion programs pay special attention on population living in the neighborhoods fraught with crime concerns.
