饮食习惯的适应，特别是西方饮食习惯的采用，可能会导致肥胖和2型糖尿病等不良健康影响。因此，有必要探讨文化适应在饮食模式中的作用，以及南亚移民对健康营养的认识和知识。这是一个特别重要的目标人群，因为南亚人的2型糖尿病和心血管疾病的患病率更高，而移民可能会放大这一比例。目前的调查是多元文化社区健康评估试验(M-CHAT)的一个子研究。最初的研究包括207名南亚裔参与者，其中129人出生在加拿大以外，并在18岁后移民。在加拿大居住的时间长短被用作适应文化的标志。一份关于自移民以来饮食模式、食物准备、营养知识和意识的感知变化的问卷被用来评估饮食实践。通过Spearman相关分析探讨居住时间与感知的饮食结构变化相关变量之间的关联，随后通过调整了年龄、性别、教育程度和体重指数的有序Logistic回归分析来分析显著关联。在加拿大的南亚移民报告了各种积极的饮食做法，包括增加水果和蔬菜的消费和改进食物准备(包括增加烧烤和减少烹饪时的油炸)。然而，据报道，方便食品、含糖饮料、红肉和外出就餐的消费量有所增加。在加拿大的南亚移民报告了各种积极的饮食习惯，包括改进食物准备。未来的健康促进战略应鼓励文化敏感度，努力减少含糖饮料和方便食品的消费，并鼓励在家中就餐，而不是外出就餐。
Dietary acculturation, specifically the adoption of western dietary habits, may result in adverse health effects such as obesity and type 2 diabetes. Therefore, it is necessary to explore the role of acculturation in dietary patterns as well as awareness and knowledge of healthy nutrition among South Asian immigrants. This is an especially important population to target as South Asians have higher prevalence rates of type 2 diabetes and cardiovascular disease, which may be magnified with immigration. The current investigation is a sub-study of the Multi-Cultural Community Health Assessment Trial (M-CHAT). There were 207 participants of South Asian origin included in the initial study, 129 were born outside of Canada and had immigrated after the age of 18. The length of residence in Canada was used as a marker for acculturation. A questionnaire addressing perceived changes in dietary patterns, food preparation, and nutrition knowledge and awareness since immigration was used to assess dietary practices. The association between length of residence and variables related to perceived changes in dietary patterns was explored with Spearman correlation and significant associations were subsequently analyzed with ordinal logistic regression analysis adjusted for age, sex, education and body mass index. South Asian immigrants in Canada reported a variety of positive dietary practices, including an increased consumption of fruits and vegetables and an improvement in food preparation (including an increase in grilling and a decrease in deep frying when cooking). However, there was a reported increase in the consumption of convenience foods, sugar-sweetened beverages, red meat and in dining out. South Asian immigrants in Canada reported a variety of positive dietary practices including an improvement in food preparation. Future health promotion strategies should encourage cultural sensitivity in efforts to reduce the consumption of sugar-sweetened beverage, convenience foods and to encourage eating at home rather than dining out.
