The relationships of relative weight to energy intake and to physical activity were studied among 141 females aged 34-59 y. As observed in previous studies Quetelet index (wt/ht2) was inversely related to energy intake (r = -0.11). However, obese women tended to be older (r = 0.16), exercise less (r = -0.30), and drink less alcohol (r = -0.16) than nonobese women. Older women had lower energy intake (r = -0.23) and exercised less (r = -0.12) than younger women. Energy intake and physical activity were positively related (r = 0.23). After adjustment for age, physical activity, alcohol, and smoking, the inverse correlation between relative weight and energy intake was significantly reduced (p = 0.04) from r = -0.11 to r = -0.02. Obese women reported higher intakes of total fat, and relative weight was significantly correlated with intakes of total fat (r = 0.20) and saturated fatty acids (r = 0.16). These data highlight the importance of considering factors that may confound the relationship between energy intake and obesity, and they suggest that fat intake may play a role in obesity that is independent of total energy intake.
对141名年龄在34至59岁之间的女性的相对体重与能量摄入以及身体活动之间的关系进行了研究。正如之前研究所观察到的，奎特利指数（体重/身高²）与能量摄入呈负相关（r = -0.11）。然而，肥胖女性往往比非肥胖女性年龄更大（r = 0.16），运动量更少（r = -0.30），饮酒量更少（r = -0.16）。年龄较大的女性比年轻女性能量摄入更低（r = -0.23），运动量更少（r = -0.12）。能量摄入与身体活动呈正相关（r = 0.23）。在对年龄、身体活动、饮酒和吸烟进行调整后，相对体重与能量摄入之间的负相关从r = -0.11显著降低至r = -0.02（p = 0.04）。肥胖女性报告的总脂肪摄入量更高，相对体重与总脂肪摄入量（r = 0.20）和饱和脂肪酸摄入量（r = 0.16）显著相关。这些数据突出了考虑可能混淆能量摄入与肥胖之间关系的因素的重要性，并且表明脂肪摄入可能在肥胖中发挥独立于总能量摄入的作用。
