为了评估从食物频率问卷估计的营养摄入量的有效性，作者比较了预先形成的视黄醇(饮食加补充剂)、β-胡萝卜素、其他活性类胡萝卜素和总维生素A的摄入量估计值，这些估计是根据调查问卷的回答与血清类维A和类胡萝卜素浓度计算得出的。数据来自华盛顿州西雅图弗雷德·哈钦森癌症研究中心1985年至1986年期间参加肺癌化学预防试验的302名男性和女性现在或以前吸烟者。血清β-胡萝卜素和血清a-胡萝卜素都与食物频率估计的总维生素A摄入量、膳食维生素A、β-胡萝卜素、其他类胡萝卜素和总类胡萝卜素有关(0.18≤r≤0.26)。血清视黄醇与补充维生素A摄入量呈正相关(r=0.16)。非饮食因素也与血清营养浓度有关--特别是吸烟、饮酒和体重指数。吸烟是血清β-胡萝卜素与膳食β-胡萝卜素关系的重要修正因素(现吸烟者r=0.14，既往吸烟者r=0.30)。
To assess the validity of nutrient intake estimates from a food frequency questionnaire, the authors compared estimates of intake of preformed retinol (dietary plus supplements), β-carotene, other active carotenoids, and total vitamin A computed from questionnaire responses with serum retinoid and carotenoid concentrations. Data were obtained from 302 male and female current or former smokers, participants in a lung cancer chemoprevention trial at the Fred Hutchinson Cancer Research Center in Seattle, Washington, during 1985–1986. Both serum β-carotene and serum a-carotene were associated, although weakly, with food frequency estimates of total vitamin A intake, dietary vitamin A, β-carotene, other carotenoids, and total carotenoids (0.18≤ r≤0.26). Serum retinol was associated with supplementary vitamin A intake (r=0.16). Nondietary factors were also associated with serum nutrient concentrations—in particular, cigarette smoking, alcohol intake, and body mass index. Cigarette smoking emerged as an important modifying factor of the relation between serum β-carotene and dietary β-carotene (r=0.14 for current smokers, r=0.30 for former smokers).
