Item Influence of socioeconomic status on changes in body size and physical activity in ageing black South African women(BioMed Central, 2018-04) Gradidge, Philippe Jean-Luc; Norris, Shane A.; Munthali, Richard; Crowther, Nigel J.Background: The increasing prevalence of obesity in sub-Saharan African women is not well understood, and black South African women in the region are particularly vulnerable. This study aimed to examine whether the relationship of socioeconomic status (SES) with changes in body mass index (BMI) and waist circumference (WC) is mediated by physical activity in ageing African women. Methods: In a longitudinal analysis of the 518 caregivers associated with the Birth to Twenty Plus study, the role of SES associated with 10-year changes in BMI and WC was tested using structural equation modelling (SEM). The degree of mediation of moderate-vigorous physical activity (MVPA) and sitting time in this association was also assessed. Results: The prevalence of obesity increased significantly from baseline to follow-up (p < 0.0001). In the SEM models, baseline SES had a direct positive effect on changes in BMI (β, 95% CI, 0.02 (0.005 to 0.04), and a direct negative effect on changes in MVPA (β, 95% CI, − 3.81 (− 6.92 to − 0.70). Baseline MVPA had a direct negative effect (β, 95% CI, − 0.002 (− 0.003 to − 0.0003) and indirect positive effect via change in MVPA (β, 95% CI, 0.01 (0.0001 to 0.001) on change in WC. Conclusions: Our study demonstrates the role and interaction of sociodemographic and behavioural predictors of obesity and suggests a multifaceted approach to management of the crisis in communities of ageing urban African women.Item A duty of support for all South African unmarried intimate partners Part I: the limits of the cohabitation and marriage based models(North-West University, 2018-10-19) Bonthuys, ElsjeThe democratic Constitutional dispensation has led to the gradual extension of spousal duties of support to unmarried couples who hitherto could not legally claim support from their partners or from third parties who had unlawfully caused the death of their partners. The new recipients of rights to support can be divided into three groups: wives in Muslim religious marriages, partners in same-sex intimate relationships and unmarried opposite sex cohabitants whose relationships closely resemble civil marriage in both form and function. However, certain distinctive features of customary marriage, the continuing consequences of apartheid policies for African families and certain distinctive patrilineal features of traditional African families have largely excluded African women – who constitute the largest and most economically vulnerable group of women – from the benefits of these developments. Part one of this two-part article analyses the trajectory of the developing right to support intimate partnerships which appear to be based either on marriage (in the case of Muslim marriages) or relationships similar to marriage, including monogamy and permanent co-residence in the case of same-sex and opposite sex partners. This leaves no room to extend rights to unmarried intimate partners whose relationships do not fit the template of civil marriage and, in particular, excludes many disadvantaged African women from obtaining legal rights to support from their relationships.
