Item Consumption patterns of street food consumers in Cape Town(South African Association of Family Ecology and Consumer Sciences (SAAFECS)., 2016) Hill, Jillian; Mchiza, Zandile; Fourie, Jean; Puoane, Thandi; Steyn, NeliaStreet foods (SF) contribute significantly to the diet of people living in low- and middle-income countries, however there is a paucity of data on consumption patterns of SF. Since many South Africans consume SF regularly, it is important to determine their purchasing habits, food choices, and nutrition knowledge. A cross-sectional survey conducted in Cape Town metropolitan area, with trained fieldworkers using a structured questionnaire on 1121 SF consumers. The first ten clients who visited a randomly-sampled SF vendor were approached and invited to participate. Data were analysed using IBM Statistics SPSS version 23. Most consumers were black, male, single, and had some high-school education and/or matriculated. Main findings indicated that 38% of these consumers consumed SF almost daily, 43.3% consumed SF frequently (2-3 times per week) and 29% spent between R600 and R899 per month on SF. Items purchased most often in descending order of frequency were fruit, foods and baked products, cold drinks, sweets, peanuts, crisps, fruit juice, biscuits, and chocolates. If healthier SF were available, 96% consumers indicated they would purchase these, with fruit, meat/chicken and vegetable stew, yoghurt and nuts being preferred options. There is a large market for SF consumers in Cape Town. However, most food items consumed, with the exception of fruit and peanuts, are unhealthy by virtue of their high sugar and fat content. SF consumers are however, willing to purchase healthier foods, should these be available.Item The risk of metabolic syndrome as a result of lifestyle among Ellisras rural young adults(Nature Publishing Group, 2018) Sekgala, M. D.; Monyeki, K. D.; Mogale, A.; Mchiza, Zandile; Parker, W.; Choma, S. R.; Makgopa, H. M.The study aimed to investigate the association between metabolic syndrome (MetS) and lifestyle risk factors among Ellisras adults. A cross-sectional study was conducted on 624 adults (306 males and 318 females). MetS was defined according to the criteria of the International Diabetes Federation. The prevalence of MetS was 23.1% (8.6% males and 36.8 % females). Females appeared to have higher mean values for waist circumference (WC), fasting blood glucose (FBG), total cholesterol (TCHOL) and low-density lipoprotein cholesterol (LDL-C), while males had high mean values for high-density lipoprotein cholesterol (HDL-C), triglycerides (TG), systolic blood pressure (SBP) and diastolic blood pressure (DBP). No significant age and gender differences were observed for dietary intake. Significantly more females (51.9%) presented with increased WC than males (4.6%). Participants who had a high dietary energy intake were significantly less likely to present with larger WC (OR: 0.250 95% CI [0.161; 0.389]), low HDL-C (OR: 0.306 95% CI [0.220; 0.425]) and high LDL-C (OR: 0.583 95% CI [0.418; 0.812]) but more likely to present with elevated FBG (OR: 1.01 95% CI [0.735; 1.386]), high TCHOL (OR: 1.039 95% CI [0.575; 1.337]), high TG (OR: 1.186 95% CI [0.695; 2.023]) and hypertension (OR: 5.205 95% CI [3.156; 8.585]). After adjusting for age, gender, smoking, and alcohol status, high energy intake was more than two times likely to predict MetS in adults with a large WC (OR: 2.766 95% CI [0.863; 3.477] and elevated FBG (OR: 2.227 95% CI [1.051; 3.328]). Therefore, identifying groups that are at an increased risk and those that are in their early stages of MetS will help improve and prevent the increase of the MetS in the future.
