The association of dietary energy density (ED) and overweight is not clear in the literature. Our aim was to study in 4259 of the PREDIMED trial whether an increase in dietary ED based on a higher adherence to a Mediterranean dietary pattern was associated with 3-year weight gain. A validated 137-item food-frequency questionnaire was administered. Multivariable-adjusted models were used to analyze the association between 3-year ED change and the subsequent 3-year body weight change. The most important weight reduction after 3-year follow-up was observed in the two lowest quintiles and the highest quintile of ED change. The highest ED increase was characterized by an increased intake of extra virgin olive oil (EVOO) and nuts and a decreased intake of other oils, vegetable and fruit consumption (p < .001). In conclusion, increased 3-year ED in the PREDIMED study, associated with a higher EVOO and nuts consumption, was not associated with weight gain.
饮食能量密度（ED）与超重之间的关联在文献中并不明确。我们的目的是在PREDIMED试验的4259名参与者中研究，基于对地中海饮食模式更高的依从性而导致的饮食ED增加是否与3年体重增加有关。采用了一份经过验证的包含137个条目的食物频率问卷。使用多变量调整模型来分析3年ED变化与随后3年体重变化之间的关联。在3年随访后，ED变化的两个最低五分位数组和最高五分位数组观察到了最显著的体重减轻。ED增加最多的特征是特级初榨橄榄油（EVOO）和坚果摄入量增加，而其他油类、蔬菜和水果的摄入量减少（p < 0.001）。总之，PREDIMED研究中3年ED增加与更高的EVOO和坚果摄入量相关，但与体重增加无关。
