Perceptions of Diet, Physical Activity, and Obesity-related Health Among Black Daughter-mother Pairs in Soweto, South Africa: a Qualitative Study

Background: The prevalence of overweight and obesity is on the rise in South Africa, particularly among females living in urban environments. The purpose of this qualitative study was to explore the emic perspectives of black young adult daughter and mother pairs living in Soweto, South Africa on diet, physical activity, and obesity-related health within their social and cultural context.

Methods: Purposeful sampling was used to recruit daughters with a normal body mass index (BMI) who have obese mothers. Individual semi-structured in-depth interviews were conducted with 17 daughters (age 24 years) and 15 of their mothers in Soweto, South Africa. Interview questions related to: a) eating and physical activity behaviors and perceptions, b) perceptions of social and community level factors, c) cultural beliefs about diet and body image, and d) intergenerational relationships. Data were analyzed using four-phases of thematic analysis and the constant comparison approach.

Results: Daughters and mothers had similar ideas of the definition of healthy food and the importance of eating healthy, but mothers were more likely to report eating healthy because of their age, adverse health experiences, and a desire to live longer. Daughters and mothers engaged in physical activity for reasons related to weight maintenance and feeling better, but mothers reported being more likely to start exercising as a result of a health concern. Daughters and mothers had comparable views of what makes a person healthy. Daughters and mothers relied on each other for food purchasing and food preparation.

Conclusion: Daughters and mothers shared some similar perceptions of diet, physical activity, and health that were rooted in their daily life in Soweto. However, mothers generally reported being more likely to exhibit healthy eating and physical activity behaviors despite being obese. The mothers may have adopted these perceptions and behaviors later in life linked to ageing and ill-health. It is possible that through exposure, their daughters have assimilated these perceptions earlier in childhood or adolescence. It is important to focus health promotion efforts around preventing the otherwise expected increase of obesity among the young adult generation.
