关于饮食行为和饮食质量对体重指数（BMI）的影响的流行病学证据很少，BMI可能是肥胖流行的重要驱动因素。这项研究利用国际宏观/微量营养素与血压研究（INTERMAP）的数据，调查了饮食频率和摄入时间与能量密度、营养质量和BMI之间的关系，研究对象包括来自美国和英国的2696名年龄在40-59岁之间的男性和女性。INTERMAP是一项横断面调查，在1996年至1999年间进行了四次24小时饮食回顾和BMI测量。固体食物的消耗被汇总到进食场合。营养密度用营养丰富食品（NRF 9.3）指数表示。计算早晚能量摄入比；采用四次就诊的平均值。不同饮食场合的特征以调整后的平均值表示，并具有相应的95%置信区间。采用多元线性回归模型检验饮食场合、早晚能量摄入比、膳食能量密度和NRF 9.3指数与BMI的关系。与进食次数< 4次/24小时的参与者相比，进食次数≥6次/24小时的参与者平均BMI: 27.3 vs 29.0 kg/m2；总能量摄入：2,129 vs. 2,472 kcal/24小时；膳食能量密度：1.5 vs. 2.1 kcal/g；NRF 9.3指数更高：34.3比28.1。在多元回归分析中，与早晨摄入量相比，晚上摄入量较高与BMI直接相关；然而，这并不影响饮食频率和体重指数之间的关系。我们的研究结果表明，大量的小餐可能与改善饮食质量和降低BMI有关。这可能会对控制肥胖流行的行为方法产生影响。
Epidemiologic evidence is sparse on the effect of dietary behaviors and diet quality on body mass index (BMI) that may be important drivers of the obesity epidemic. This study investigated the relationships of frequency of eating and time of intake to energy density, nutrient quality and BMI using data from the INTERnational study on MAcro/micronutrients and blood Pressure (INTERMAP) including 2,696 men and women aged 40-59 from the United States and the United Kingdom. INTERMAP is a cross-sectional investigation with four 24-hour dietary recalls and BMI measurements conducted between 1996 and 1999. Consumption of solid foods was aggregated into eating occasion. Nutrient density is expressed using the Nutrient Rich Food (NRF 9.3) index. The ratio of evening/morning energy intake was calculated; mean values of four visits were used. Characteristics across eating occasion categories are presented as adjusted mean with corresponding 95% confidence interval. Multiple linear regression models were used to examine associations of eating occasions, ratio of evening/morning energy intake, dietary energy density, and NRF 9.3 index with BMI. Compared to participants with < 4 eating occasions/24-hours, those with ≥ 6 eating occasions/24-hours had lower mean: BMI: 27.3 vs. 29.0 kg/m2; total energy intake: 2,129 vs. 2,472 kcal/24-hours; dietary energy density: 1.5 vs. 2.1 kcal/g; and higher NRF 9.3 index: 34.3 vs. 28.1. In multiple regression analyses, higher evening intake relative to morning intake was directly associated with BMI; however this did not influence the relationship between eating frequency and BMI. Our results suggest that a larger number of small meals may be associated with improved diet quality and lower BMI. This may have implications for behavioral approaches to controlling the obesity epidemic.
