The purpose of the present study was to identify energy intake (EI) underreporting and to estimate the impact of using a population specific equation for the basal metabolic rate (BMR) in a probability sample of adults from Niterói, Rio de Janeiro State, Brazil. A sample of 1,726 subjects participated in the study. EI was assessed by a 24-hour dietary recall and EI/BMR was computed with BMR estimated using internationally recommended equations as well as specific equations developed for the adult population of Niterói. Mean EI was 1,570.9 and 2,188.8 kcal.day-1 for women and men, respectively. EI decreased with increasing age in both men and women. BMR estimated by the Brazilian equation was significantly lower than the values estimated by the international equation for all age, sex and nutritional status groups. In general, EI underreporting was found in at least 50% of the population, higher in women, and increased with increasing age and body mass index (BMI). The results of the present study confirm that EI is underreported, even when BMR is estimated using population-specific equations.
本研究的目的是识别能量摄入（EI）报告不足的情况，并估计在巴西里约热内卢州尼泰罗伊市成年概率样本中使用特定人群基础代谢率（BMR）方程的影响。1726名受试者参与了该研究。通过24小时饮食回顾评估EI，并使用国际推荐方程以及为尼泰罗伊成年人群开发的特定方程估计的BMR来计算EI/BMR。女性和男性的平均EI分别为1570.9和2188.8千卡/天。EI在男性和女性中均随年龄增长而降低。巴西方程估计的BMR在所有年龄、性别和营养状况组中均显著低于国际方程估计的值。总体而言，至少50%的人群存在EI报告不足的情况，女性中更高，且随年龄和体重指数（BMI）的增加而增加。本研究结果证实，即使使用特定人群方程估计BMR，EI仍存在报告不足的情况。
