To detect predictive variables of weight changes in non-obese women.
Three year follow-up study.
Fifty-eight women (age 40.0+/-12.8 y, height 159+/-7 cm, weight 62.5+/-9.6 kg and body mass index ((BMI) 24.7+/-3.7 kg/m2).
At baseline, basal metabolic rate (BMR) and respiratory quotient (RQ) by indirect calorimetry. Weight and BMI at baseline and after 3 y.
In both univariate and multivariate analyses, age and RQ at baseline were significant predictors (P<0.05) of subsequent changes in weight and BMI.
In non-obese women, RQ and age are independent predictors of subsequent weight changes.
检测非肥胖女性体重变化的预测变量。
三年随访研究。
58名女性（年龄40.0±12.8岁，身高159±7厘米，体重62.5±9.6千克，体重指数（BMI）24.7±3.7千克/平方米）。
基线时通过间接测热法测量基础代谢率（BMR）和呼吸商（RQ）。记录基线时及3年后的体重和BMI。
在单变量和多变量分析中，基线时的年龄和RQ是随后体重和BMI变化的显著预测因素（P<0.05）。
在非肥胖女性中，RQ和年龄是随后体重变化的独立预测因素。
