Diabetes is a world-wide epidemic associated with multiple environmental factors. Prolonged television viewing (TV) time has been related to increased risk of obesity and type 2 diabetes in several studies. TV viewing has been positively associated with cardiovascular disease risk factors, lower energy expenditure, over-eating high-calorie and high-fat foods. The objective of this study was to assess the associations of hours of TV viewing with dietary quality, obesity and physical activity for three ethnic minorities with and without type 2 diabetes. Diet quality and physical activity were inversely related to prolonged TV viewing. African Americans and participants with type 2 diabetes were more likely to watch more than 4 hours of TV per day as compared to their counterparts. Diet quality was inversely associated with physical activity level. Future studies are needed to establish the risk factors of prolonged TV watching in adult populations for the development of diabetes or diabetes-related complications. Although strategies to reduce TV watching have been proven effective among children, few trials have been conducted in adults. Intervention trials aimed at reducing TV viewing targeting people with type 2 diabetes may be beneficial to improve dietary quality and physical activity, which may reduce diabetes complications.
糖尿病是一种全球性的流行病，与多种环境因素有关。多项研究表明，长时间看电视（TV）与肥胖和 2 型糖尿病的风险增加有关。看电视与心血管疾病的危险因素、能量消耗减少、过度食用高热量和高脂肪食物有关。本研究的目的是评估看电视时间与三种少数民族（有无 2 型糖尿病）的饮食质量、肥胖和身体活动之间的关系。饮食质量和身体活动与长时间看电视呈负相关。与对照组相比，非裔美国人和 2 型糖尿病患者每天看电视超过 4 小时的可能性更大。饮食质量与身体活动水平呈负相关。未来需要进行更多研究，以确定成年人长时间看电视与糖尿病或糖尿病相关并发症发展的相关风险因素。虽然已经证明减少儿童看电视的策略是有效的，但在成年人中进行的试验很少。针对 2 型糖尿病患者的减少看电视时间的干预试验可能有益于改善饮食质量和身体活动，从而减少糖尿病并发症。
