A cross-sectional study was applied to investigate the influence of food systems and food environments on food choices and nutrition transition of households in Limpopo province, South Africa. A sample of 429 households was systematically selected using a paper selection draw from three districts. This paper determines the association among food systems, food environments, food choices, and nutritional measurements of the respondents. A validated questionnaire was used. Most of the respondents responsible for food procurement were females (80.4%). There was a significant association ( < 0.001) between proximity to food stores and dietary diversity of the households. Staple foods such as bread, maize, rice, samp, and mealie rice were available in almost all surveyed households (95.6%). More than half of the households (59.8%) had home gardens in their yards. Almost half of the households (48.4%) had a low Dietary Diversity Score. The study further revealed that 46.0% of households were food secure. Over a third (36.2%) of the respondents were obese, and 32.5% were diabetic. The mean total blood cholesterol was 3.69 ± 0.74 mmol/L. A high percentage of both females (89.6%) and males (91.5%) had normal hemoglobin levels. Almost half of the respondents had normal systolic blood pressure levels (45.6%), and nearly a quarter had high diastolic levels (21.4%). The 25 coping strategies were applied during food shortage periods. Even though the food environments provided both obesogenic and protective foods, the consumption of unhealthy foods was high.
一项横断面研究应用于调查南非林波波省家庭的食物系统和食物环境对食物选择和营养转型的影响。使用从三个地区的纸张选择抽取的系统抽样方法选择了 429 户家庭作为样本。本文确定了食物系统、食物环境、食物选择和受访者营养测量之间的关联。使用了经过验证的问卷。负责采购食物的受访者中大多数是女性(80.4%)。家庭接近食物商店与家庭饮食多样性之间存在显著关联(<0.001)。面包、玉米、大米、 samp 和玉米粉等主食几乎在所有调查家庭中都有供应(95.6%)。超过一半的家庭(59.8%)在院子里有家庭菜园。几乎一半的家庭(48.4%)的饮食多样性得分较低。研究还表明,46.0%的家庭是粮食安全的。超过三分之一(36.2%)的受访者肥胖,32.5%的受访者患有糖尿病。平均总血胆固醇为 3.69±0.74mmol/L。女性(89.6%)和男性(91.5%)的血红蛋白水平正常的比例都很高。近一半的受访者的收缩压水平正常(45.6%),近四分之一的舒张压水平高(21.4%)。在食物短缺期间应用了 25 种应对策略。尽管食物环境提供了肥胖和保护食物,但不健康食物的消费仍然很高。
