The objective of this study was to examine the extent of underreporting of total energy intake and associated factors in a low-income, low-literacy, predominantly Caribbean Latino community in Lawrence, MA. Two hundred fifteen Latinos participated in a diabetes prevention study, for which eligibility included a >or=30% risk of developing diabetes in 7.5 years. Dietary self-reported energy intake was assessed using three randomly selected days of 24-hour diet recalls. Basal metabolic rate (BMR) was estimated using the Mifflin-St Jeor equation. Underreporting was determined by computing a ratio of energy intake to BMR, with a ratio of 1.55 expected for sedentary populations. Linear regression analyses were used to identify factors associated with underreporting (energy intake:BMR ratio). The population was predominately women (77%), middle-aged (mean 52+/-11 years), obese (78% had a body mass index >or=30); low-literate (62% < high school education), unemployed (57% reported no job), married or living with partner (52%), and some had a family history of diabetes (37% had siblings with diabetes). Reported total daily energy intake was 1,540+/-599 kcal, whereas estimated BMR was 1,495.7+/-245.1 kcal/day. When multiplied by an activity factor (1.20 for sedentariness), expected energy intake was 1,794+/-294.0 per day, indicating underreporting by an average of 254 kcal/day. Mean energy intake:BMR was 1.03+/-0.37, and was lower for participants with higher body mass index, siblings with diabetes, sedentary lifestyle, and those who were unemployed. Energy intake underreporting is prevalent in this low-income, low-literacy Caribbean Latino population. Future studies are needed to develop dietary assessment measures that minimize underreporting in this population.
本研究的目的是调查马萨诸塞州劳伦斯市一个低收入、低文化水平、以加勒比裔拉丁裔为主的社区中总能量摄入漏报的程度及相关因素。215名拉丁裔参与了一项糖尿病预防研究，入选条件包括在7.5年内患糖尿病的风险≥30%。通过随机选择三天进行24小时饮食回顾来评估饮食自我报告的能量摄入。使用米夫林-圣乔尔方程估算基础代谢率（BMR）。通过计算能量摄入与BMR的比值来确定漏报情况，久坐人群的预期比值为1.55。采用线性回归分析来确定与漏报（能量摄入:BMR比值）相关的因素。研究人群主要为女性（77%），中年（平均年龄52±11岁），肥胖（78%的体重指数≥30）；文化水平低（62%未接受高中教育），失业（57%报告无工作），已婚或与伴侣同住（52%），部分人有糖尿病家族史（37%的兄弟姐妹患有糖尿病）。报告的每日总能量摄入为1540±599千卡，而估算的BMR为1495.7±245.1千卡/天。乘以活动系数（久坐为1.20）后，预期能量摄入为每天1794±294.0千卡，表明平均每天漏报254千卡。平均能量摄入:BMR为1.03±0.37，体重指数较高、有患糖尿病的兄弟姐妹、久坐的生活方式以及失业者的该比值较低。在这个低收入、低文化水平的加勒比裔拉丁裔人群中，能量摄入漏报现象普遍存在。未来需要开展研究，以制定能尽量减少该人群漏报情况的饮食评估方法。
