鉴于当前肥胖流行，膳食碳水化合物在减肥中的作用受到了相当多的关注。作者利用对马萨诸塞州中部 572 名健康成年人进行的一项观察性研究的数据，调查了体重指数（体重 (kg)/身高 (m)(2)）与膳食碳水化合物摄入量以及诱发血糖反应测量值之间的关系。在为期 1 年的研究期间，每季度收集每位受试者的人体测量数据、7 天饮食回忆和体力活动回忆。数据收集于 1994 年至 1998 年间。进行了纵向分析，并根据与身体习性相关的其他因素对结果进行了调整。平均体重指数为27.4 kg/m(2)（标准差，5.5），而碳水化合物的平均热量百分比为44.9（标准差，9.6）。平均每日膳食血糖指数为81.7（标准差，5.5），血糖负荷为197.8（标准差，105.2）。研究发现，体重指数与血糖指数呈正相关，血糖指数是衡量与摄入不同类型碳水化合物相关的血糖反应的指标，但与每日碳水化合物摄入量、碳水化合物卡路里百分比或血糖负荷无关。结果表明碳水化合物的类型可能与体重有关。然而，需要进一步的研究来阐明这种关联及其对体重管理的影响。
The role of dietary carbohydrates in weight loss has received considerable attention in light of the current obesity epidemic. The authors investigated the association of body mass index (weight (kg)/height (m)(2)) with dietary intake of carbohydrates and with measures of the induced glycemic response, using data from an observational study of 572 healthy adults in central Massachusetts. Anthropometric measurements, 7-day dietary recalls, and physical activity recalls were collected quarterly from each subject throughout a 1-year study period. Data were collected between 1994 and 1998. Longitudinal analyses were conducted, and results were adjusted for other factors related to body habitus. Average body mass index was 27.4 kg/m(2) (standard deviation, 5.5), while the average percentage of calories from carbohydrates was 44.9 (standard deviation, 9.6). Mean daily dietary glycemic index was 81.7 (standard deviation, 5.5), and glycemic load was 197.8 (standard deviation, 105.2). Body mass index was found to be positively associated with glycemic index, a measure of the glycemic response associated with ingesting different types of carbohydrates, but not with daily carbohydrate intake, percentage of calories from carbohydrates, or glycemic load. Results suggest that the type of carbohydrate may be related to body weight. However, further research is required to elucidate this association and its implications for weight management.
