Physical inactivity remains a significant concern in black South African women increasing risk of non-communicable diseases and perceptions of body size. Pressure from family and friends increase the risk of dissatisfaction in black South African women. The aim was to determine effects of physical activity intervention on body size dissatisfaction.in a sample of black South African women. Methods: An experimental study conducted in black South African women aged 18 years and older (n=115). Data were collected on anthropometry (body mass index (BMI), waist and hip circumferences) and blood pressure. A standardized questionnaire determined socioeconomic status (SES); Stunkard silhouettes were used for body size dissatisfaction. The Global Physical Activity Questionnaire was used for physical activity. The study included n=66 females for the control group and n=49 for the intervention group. The intervention was a supervised walking programme for 12 weeks . Paired sample t-test determined changes in anthropometry and physical activity from baseline to follow-up. Statistica version13.2 was used for statistical analysis. Results: Total sitting time was positively associated with BMI:β: 0.18, P=0. 0001. Women who wanted to be fatter were 12.12%, 4.54% were content and 83.3% wanted to be leaner. Total Moderate Vigorous Physical Activity (MVPA) was positively associated with body size (MVPA β= 0.14, P= 0.0001). Conclusion: Body size dissatisfaction increased with BMI in the intervention group. There was an improvement in anthropometry and blood pressure following physical activity intervention.Online resource (88 leaves)Physical fitnessExerciseenThesis
