Relationship between sedentary lifestyle patterns and obesity among adults in Ha-Tshikundamalema Area of Limpopo Province, South Africa
Sedentary lifestyle may contribute to obesity and non-communicable diseases, which are the major public health problem in South Africa. This study investigated the relationship between sedentary lifestyle and obesity among adults in Ha-Tshikundamalema area. A quantitative descriptive cross-sectional study among 298 participants (116 males and 182 females) aged 20-60 years, sampled systematically was conducted. Socio-demographic and, sedentary lifestyle and physical activity information was collected using a questionnaire, while anthropometric indices were measured according to ISAK protocol. Data were analysed using SPSS, version 24.0; where Pearson correlation and linear regression analyses to determine significant predictors of obesity were performed. The prevalence of TV viewing and low participation in moderate-vigorous activity were 75.8%, 69.1% and 82.6%, respectively. Twenty-nine point nine percent and 27.2% were overweight and obese, while 26.8% had very high WC (central obesity). According to Pearson correlation, TV viewing time, food, household activity, walking days and time, vigorous activity work vigorous activity, female gender, age (30-39), being married, unemployment, smoking and alcohol consumption were significantly related to BMI and WC. No significant association was found between most of the sedentary behaviours, level of education and socio-economic status. However, obesity was more prevalent among those with less education and low socio-economic status. In regression analyses, only TV viewing time, work vigorous activity, gender, being married and smoking were the independent and significant predictors of high BMI and WC (obesity) (P< 0.05). There was an association of sedentary lifestyle and socio-demographic characteristics, and obesity. Intervention to prevent sedentary lifestyle and obesity should target females, particularly married, unemployed and those with less level of education.
