We examined the effect of television viewing and walking on the risk of type 2 diabetes among an Asian population. A total of 25,240 participants (9786 men and 15,454 women) aged 40-79 years, with no history of diabetes, stroke, coronary heart disease, or cancer at the baseline (1988-1990) and who have completed the 5-year follow-up questionnaire were included. During the 5-year follow-up, 778 new cases of type 2 diabetes were reported (397 men and 381 women). Television viewing time was positively associated with risk of type 2 diabetes (p for trend = 0.01). The multivariable OR (95% CI) for ≥5 h/day versus <2 h/day television viewing was 1.51 (1.03-2.19) in women and 1.06 (0.71-1.59) in men (p for interaction = 0.82). Walking time was inversely associated with type 2 diabetes risk in a fully adjusted model (p for trend = 0.02). The multivariable OR for type 2 diabetes of ≥1 h/day walking time was 0.87 (0.71-1.06) compared with 0.5 h/day walking time. The inverse association was found in men (p for trend = 0.02), but not in women (p for trend = 0.38) (p for interaction = 0.36). The multivariable OR for type 2 diabetes of <5 h/day television viewing and ≥1 h/day walking times was 0.72 (0.55-0.94) in fully adjusted model compared with ≥5 h/day television viewing and <1 h/day walking times. Limiting television viewing time and increasing walking time may reduce risk of type 2 diabetes among Japanese.
我们研究了在亚洲人群中，看电视和散步对 2 型糖尿病风险的影响。共有 25240 名参与者（男性 9786 人，女性 15454 人）年龄在 40-79 岁之间，在基线时（1988-1990 年）没有糖尿病、中风、冠心病或癌症病史，并且完成了 5 年随访问卷。在 5 年随访期间，报告了 778 例新的 2 型糖尿病病例（男性 397 例，女性 381 例）。看电视的时间与 2 型糖尿病的风险呈正相关（趋势检验 p=0.01）。与每天看电视<2 小时相比，每天看电视≥5 小时的女性患 2 型糖尿病的多变量 OR（95%CI）为 1.51（1.03-2.19），男性为 1.06（0.71-1.59）（交互检验 p=0.82）。在完全调整的模型中，散步时间与 2 型糖尿病风险呈负相关（趋势检验 p=0.02）。与每天散步时间 0.5 小时相比，每天散步时间≥1 小时的 2 型糖尿病的多变量 OR 为 0.87（0.71-1.06）。这种负相关仅在男性中存在（趋势检验 p=0.02），而在女性中则不存在（趋势检验 p=0.38）（交互检验 p=0.36）。在完全调整的模型中，与每天看电视≥5 小时且散步时间<1 小时相比，每天看电视<5 小时且散步时间≥1 小时的 2 型糖尿病的多变量 OR 为 0.72（0.55-0.94）。限制看电视时间和增加散步时间可能会降低日本人患 2 型糖尿病的风险。
