Total muscle-strengthening and conditioning activities and risk of type 2 diabetes stratified by body mass index (2).

Data are relative risks (95% CI). Adjusted for age (months), smoking (never, past, or current), alcohol consumption (0, 1–5, >5 g/d), coffee intake (0, 5 cups/day), race (white, non-white), family history of diabetes, post menopausal hormone use (never, past, current), intake of total energy, trans fat, polyunsaturated fat to saturated fat ratio, cereal fiber, wholegrain, and glycemic load (all dietary factors in quintiles), oral contraceptive use (only NHSII: never, past, current), menopausal status (only NHSII: pre, post), and aerobic physical activity (none, 1–29, 30–59, 60–150, >150 min/week).PY, person years.本数据集所呈现的数据为相对风险（95%置信区间，CI），且经下述因素校正：年龄（以月计）、吸烟状态（从不、既往或当前吸烟）、饮酒量（0、1~5、>5克/天）、咖啡摄入量（0、5杯/天）、种族（白人、非白人）、糖尿病家族史、绝经后激素使用情况（从不、既往、当前使用）、总能量摄入、反式脂肪、多不饱和脂肪与饱和脂肪比值、谷类纤维、全谷物、血糖负荷（所有饮食因素均按五分位数分组）、口服避孕药使用情况（仅护士健康研究II（NHSII）：从不、既往、当前使用）、绝经状态（仅NHSII：绝经前、绝经后）以及有氧体力活动水平（无、1~29、30~59、60~150、>150分钟/周）。PY即人年（person years）。
