本报告描述了结构化食物频率问卷的开发和验证/校准，用于新加坡45-74岁中国男性和女性的饮食和健康的大规模队列研究，用于分析饮食数据的食物成分数据库的开发，以及饮食验证/校准研究的结果。本校准研究比较了24小时回忆的估计摄入量与食物频率问卷的估计摄入量，发现新加坡华人的能量和营养素相关系数为0.24-0.79，与其他人群校准研究中报告的相关系数相当。我们还报告了新加坡中国人的营养概况，基于对1，022名（425名男性和597名女性）队列受试者进行的1，880次24小时饮食回忆的结果。与美国白人和黑人的年龄调整相应值的比较显示，新加坡和美国人口之间的饮食摄入量存在明显差异。新加坡队列将进行前瞻性随访，以确定饮食与癌症风险和其他健康结果的关系。
This report describes the development and validation/calibration of a structured food frequency questionnaire for use in a large-scale cohort study of diet and health in Chinese men and women aged 45-74 years in Singapore, the development of a food composition database for analysis of the dietary data, and the results of the dietary validation/calibration study. The present calibration study comparing estimated intakes from 24-hour recalls with those from the food frequency questionnaires revealed correlations of 0.24-0.79 for energy and nutrients among the Singapore Chinese, which are comparable to the correlation coefficients reported in calibration studies of other populations. We also report on the nutritional profiles of Singapore Chinese on the basis of results of 1,880 24-hour dietary recalls conducted on 1,022 (425 men and 597 women) cohort subjects. Comparisons with age-adjusted corresponding values for US whites and blacks show distinct differences in dietary intakes between the Singapore and US populations. The Singapore cohort will be followed prospectively to identify dietary associations with cancer risk and other health outcomes.
