这项研究的目的是比较122名男性和179名女性年龄在40-59岁之间的吸烟者通过自我管理的食物频率问卷和10天称重记录估计的营养摄入量。营养素摄入量的比较，平均差异百分比和个人之间的方法正确排名的能力，大多数营养素显示出良好的协议。斯皮尔曼等级相关性在统计学上显着的所有营养素，除了维生素A的摄入量在男性;调整能量摄入量增加的关联发现的强度。Bland-Altman图显示，在协议的范围内的能量在男性和女性的抗坏血酸。食物频率问卷可用于评估吸烟者的饮食习惯，但需要谨慎，在应用于整个样本之前，应在研究样本中评估该方法。
The aim of the study was to compare nutrient intakes estimated by a self-administered food frequency questionnaire and a 10-day weighed record in 122 men and 179 women cigarette smokers aged 40-59 years. Comparison of nutrient intake by means, per cent mean differences and ability to rank individuals correctly between the methods showed good agreement for most nutrients. Spearman rank correlations were statistically significant for all nutrients except vitamin A intake in men; adjusting for energy intake increased the strength of the associations found. Bland-Altman plots showed differences in agreement over the range of intakes for energy in men and ascorbic acid in women. Food frequency questionnaires may be used to assess the dietary habits of smokers, but some caution is required and the method should be assessed in the study sample before being applied to the whole sample.
