目的：24 h膳食回忆法是流行病学研究中广泛使用的一种估算营养摄入量的方法。本研究的目的是估计的数量召回必要的营养摄入量的准确估计在法国成年人遵循4 y.Subjects和方法：参与者的SU.VI.MAX研究（抗氧化剂补充剂对慢性疾病的影响的干预研究）谁完成了24小时的饮食回忆每2个月至少I Y。通过方差分析计算两个时间段的个体间和个体内方差比（S-w/S-b）：第1年和第2年（n = 4955）以及第3年和第4年（n = 1458）。结果：在第一阶段，β-胡萝卜素的个体内/个体间方差比最高，碳水化合物的最低。碳水化合物和钙的摄入量需要召回5次，β-胡萝卜素需要召回16次。对于蛋白质、总脂肪和饱和脂肪、纤维、维生素C和铁，需要召回8次，而对于单不饱和脂肪和多不饱和脂肪以及维生素E，分别需要召回9次、11次和10次。第二个期间的差异率都较低，因此需要召回的次数较少。两个时间段之间的召回所需的数量相同的差异，观察时，只有那些受试者包括谁完成了至少18召回（n = 727）。结论：这些结果表明，准确估计碳水化合物的摄入量，已经有五个召回是必要的。赞助：SUNWAX研究得到了公共和私营部门的支持：Fruit d 'Or Recherche，Candia，Lipton，凯洛格，Cereal，CERIN，Estee Lauder，L' Oreal，Peugeot，Jet Service，RP谢勒，Soclexho，France Telecom，Santogen，Becton Dickinson，Foud Springer，Boehringer Diagnostic，Seppic Givaudan Lavirotte，勒格朗Canal，Danone和Knorr。
Objective: The 24 h dietary recall is a widely used method to estimate nutritional intakes in epidemiological studies. The objective of the present study was to estimate the number of recalls necessary for an accurate estimation of nutrient intake in French adults followed for 4 y.Subjects and methods: Participants of the SU.VI.MAX study (intervention study on the effects of antioxidant supplementation on chronic diseases) who completed a 24 h dietary recall every 2 months for at least I y. Inter- and intra-individual variance ratios (S-w/S-b) were calculated by analysis of variance for two time periods: year 1 and 2 (n = 4955) and year 3 and 4 (n = 1458). The number of recalls necessary was calculated using an accuracy of 0.9.Results: The highest intra-individual/inter-individual variance ratio in the first period was seen for beta-carotene and the lowest for carbohydrate. The number of recalls necessary was five for carbohydrate and calcium intake and 16 for beta-carotene. For proteins, total and saturated fat, fibre, vitamin C and iron eight recalls were required, while nine, 11 and 10 recalls were necessary for mono- and polyunsaturated fat and vitamin E, respectively. The variance ratios in the second period were all lower and fewer recalls were therefore required. The same difference in number of recalls required between the two time periods was observed when only those subjects were included who completed at least 18 recalls (n = 727).Conclusion: These results indicate that for an accurate estimation of carbohydrate intake only, already five recalls are necessary. Fewer recalls may be needed during long-time follow-up.Sponsorship: The SUNWAX Study has support from public and private sectors: Fruit d'Or Recherche, Candia, Lipton, Kellogg's, Cereal, CERIN, Estee Lauder, L'Oreal, Peugeot, Jet Service, RP Scherer, Soclexho, France Telecom, Santogen, Becton Dickinson, Fould Springer, Boehringer Diagnostic, Seppic Givaudan Lavirotte, Le grand Canal, Danone and Knorr.
