Abstract

We aimed to analyse the association between processed food consumption and the risk of non-communicable diseases (NCDs) in South Africa. In this empirical study, we analysed nationally representative secondary data obtained from the South African Demographic and Health Survey (SADHS) VII. The survey included 13,288 occupied households, of which 11,083 were interviewed. In the interviewed households, 12,717 eligible adults aged 15 and older were identified and 10,336 were successfully interviewed. The study included four processed food groups (i.e. fried foods, takeaway foods/fast foods, salty snacks/packed chips, and processed meats) and eight NCDs (i.e. hypertension, cardiac arrest, cancer, stroke, hypercholesterolaemia, diabetes, chronic bronchitis, and asthma). As per the logistic regression results following adjustment, none of the disease states showed association with all four processed food groups. However, at least three processed food groups showed a significant positive association with hypertension, cardiac arrest, and diabetes. Two processed food groups showed significant positive association with stroke, and chronic bronchitis; one with hypercholesterolaemia and asthma; and cancer was not associated with any food groups. Processed meat and salted snacks/packed chips were each associated with five chronic conditions. In summary, we found that the consumption of any of the processed food groups increased the risk of NCDs in the South African population. Enabling policy and regulatory efforts in the production and distribution of processed foods, combined with improved awareness among the population need to be prioritised for immediate action. Facilitating the populations to choose traditional healthy diets would be a sustainable strategy for the prevention of NCDs.

南非加工食品消费与非传染性疾病(NCDs)风险:来自第七次人口与健康调查(DHS)的证据。
我们旨在分析南非加工食品消费与非传染性疾病(NCDs)风险之间的关系。在这项实证研究中,我们分析了从第七次南非人口与健康调查(SADHS)中获得的具有全国代表性的二手数据。该调查包括 13,288 个有人居住的家庭,其中 11,083 个家庭接受了访谈。在受访家庭中,我们确定了 12,717 名符合条件的 15 岁及以上成年人,并成功采访了 10,336 人。研究包括四类加工食品(即油炸食品、外卖食品/快餐食品、咸味零食/包装薯片和加工肉类)和八种非传染性疾病(即高血压、心脏骤停、癌症、中风、高胆固醇血症、糖尿病、慢性支气管炎和哮喘)。根据调整后的逻辑回归结果,没有一种疾病状态与所有四类加工食品都有关联。不过,至少有三类加工食品与高血压、心脏骤停和糖尿病呈显著正相关。两类加工食品与中风和慢性支气管炎有明显的正相关;一类与高胆固醇血症和哮喘有明显的正相关;癌症与任何食品类别都没有关系。加工肉类和腌制零食/包装薯片分别与五种慢性疾病有关。总之,我们发现食用任何一类加工食品都会增加南非人口罹患非传染性疾病的风险。在加工食品的生产和分销方面制定有利的政策和监管措施,同时提高民众的认识,这些都是需要立即采取行动的优先事项。促进民众选择传统的健康饮食将是预防非传染性疾病的可持续战略。
