在成年人中，地中海饮食模式（MDP）与体重指数（BMI）呈负相关。目前还缺乏关于美国年轻人坚持MDP的数据，以及MDP是否与该群体的体重变化有关。评估是否坚持MDP与青少年BMI变化相关。为了检查时间性，我们研究了基线和2-3年的变化之间的关系，在遵守MDP与BMI的同时变化，以及随后的变化，BMI在7年的时间。我们前瞻性地跟踪了2004年在美国各地生活的6 002名8-15岁的女性和4 916名8-15岁的男性。2004年、2006年、2008年和2011年通过问卷收集数据。饮食摄入量通过青少年问卷进行评估。导出KidMed指数以测量对MDP的依从性。我们使用广义估计方程，在受试者中重复测量，以评估MDP和BMI变化之间的关联。KidMed指数增加两个百分点与BMI增加较低独立相关（-0.04 kg/m2; p=0.001）。在同期（趋势p <0.001）和随后的时期（趋势p =0.002），KidMed指数依从性的增加与BMI的降低独立相关。在青少年中，坚持MDP与BMI的变化呈负相关。2-MDP依从性的1年改善与同期和随后阶段BMI的较低急剧增加独立相关。
Among adults, the Mediterranean dietary pattern (MDP) is inversely related to body mass index (BMI). Data are lacking on adherence to the MDP among youth in the United States and whether the MDP is related to weight change in that group. To assess whether adherence to the MDP was associated with BMI change among adolescents. To examine temporality we studied the association between baseline and 2–3 year changes in adherence to the MDP with concurrent changes in BMI, as well as subsequent changes in BMI over a 7-year period. We prospectively followed 6 002 females and 4 916 males in the Growing Up Today Study 2, aged 8–15 in 2004, living across the United States. Data were collected by questionnaire in 2004, 2006, 2008, and 2011. Dietary intake was assessed by the Youth/Adolescent Questionnaire. The KidMed Index was derived to measure the adherence to the MDP. We used generalized estimating equations with repeated measures within subjects to assess the association between MDP and BMI change. A two-point increment in the KidMed Index was independently associated with a lower gain in BMI (−0.04 kg/m2; p=0.001). A greater increase in adherence to the KidMed Index was independently related to a lower gain in BMI in both the concurrent (p-for-trend<0.001) and the subsequent period (p-for-trend=0.002). Adherence to MDP was inversely associated with change in BMI among adolescents. 2-year improvement in adherence to MDP was independently associated with less steep gain in the BMI in both the concurrent and the subsequent period.
