The association between the energy density (ED) of foods and adiposity has been reported previously. However, whether the contribution of ED to adiposity remains significant when controlled for energy intake (EI) and physical activity energy expenditure (PAEE) remains to be clearly established. We aimed to investigate the independent contribution of ED to variations in body composition in women during the menopausal transition.
Sixty-seven women from the MONET cohort study were analyzed. Seven-day food records were used to assess EI and ED. Body composition (body fat mass (FM) and trunk-fat mass (TFM)) was measured with dual-energy X-ray absorptiometry; PAEE was assessed with accelerometers. This secondary analysis of data included measurements obtained at years 1 and 5 of the study.
Mean ED was correlated with FM (r = 0.22; P = 0.04) and TFM (r = 0.22; P = 0.04) at year 1, but not at year 5. The multiple regression analysis showed that EI and ED contributed to 14% of the variance in FM and TFM at year 1.
These results suggest that ED is a modest but inconsistent determinant of adiposity in healthy women at the time of the menopause transition.
此前已有报道称食物能量密度（ED）与肥胖之间存在关联。然而，在控制能量摄入（EI）和身体活动能量消耗（PAEE）的情况下，ED对肥胖的影响是否仍然显著，仍有待明确确定。我们旨在研究ED对绝经过渡期间女性身体成分变化的独立影响。
对来自MONET队列研究的67名女性进行了分析。采用7天食物记录来评估EI和ED。使用双能X线吸收法测量身体成分（体脂肪量（FM）和躯干脂肪量（TFM））；使用加速度计评估PAEE。这项数据的二次分析包括在研究第1年和第5年获得的测量结果。
在第1年，平均ED与FM（r = 0.22；P = 0.04）和TFM（r = 0.22；P = 0.04）相关，但在第5年不相关。多元回归分析表明，在第1年，EI和ED对FM和TFM变异的贡献率为14%。
这些结果表明，在绝经过渡时期，ED是健康女性肥胖的一个适度但不一致的决定因素。
