关于饮食习惯的准确数据对于了解对疾病的影响和告知政策优先事项至关重要。联合国粮农组织的国别粮食平衡表提供了唯一可用的全球膳食估计数，但其有效性不确定。目的：我们研究了粮农组织的估计值与全球膳食数据库（GDD）中具有国家代表性的基于个人的膳食调查的比较，并开发了校准方程，以提高粮农组织数据估计膳食摄入量的有效性。设计图：粮农组织的估计值与113个国家30年（1980-2009年）的9个主要饮食指标的GDD数据相匹配：水果，蔬菜，豆类和豆类，坚果和种子，全谷物，红肉和加工肉类，鱼类和海鲜，牛奶和总能量。对粮农组织和全球数据中心平均估计数的绝对差异和百分比差异进行了评价。线性回归用于评估粮农组织的估计是否预测了GDD膳食摄入量，以及这种预测是否因年龄、性别、地区和时间而异。制定了校准公式，以调整粮农组织的估计数，使之接近使用随机分割数据集验证的国家饮食调查。结果如下：对于大多数食物类别，粮农组织估计，基于个人的膳食摄入量大大高估了74.5%（蔬菜）和270%（全谷物），而低估了豆类和豆类（-50%）以及坚果和种子（-29%）（P < 0.05）。在多元回归中，这些高估和低估的每一个饮食因素进一步变化的年龄，性别，地区和时间（P < 0.001）。分裂数据集校准模型考虑了国家层面的协变量和其他异质性来源，有效地将粮农组织的估计值调整为国家调查数据的近似估计值（r = 0.47-0.80），预测误差较小（通常为1-5克/天）。结论：对于所有食物类别和总能量，粮农组织的估计大大超过或低估了以个人为基础的全国个人摄入量调查，并因年龄、性别、地区和时间而存在显著差异。校准模型有效地调整了粮农组织广泛提供的全面数据，以便于更准确地估计全国以及按年龄和性别分列的个人膳食摄入量。
Background: Accurate data on dietary habits are crucial for understanding impacts on disease and informing policy priorities. Nation-specific food balance sheets from the United Nations FAO provided the only available global dietary estimates but with uncertain validity. Objectives: We investigated how FAO estimates compared with nationally representative, individual-based dietary surveys from the Global Dietary Database (GDD) and developed calibration equations to improve the validity of FAO data to estimate dietary intakes. Design: FAO estimates were matched to GDD data for 113 countries across the following 9 major dietary metrics for 30 y of data (1980–2009): fruit, vegetables, beans and legumes, nuts and seeds, whole grains, red and processed meats, fish and seafood, milk, and total energy. Both absolute and percentage differences in FAO and GDD mean estimates were evaluated. Linear regression was used to evaluate whether FAO estimates predicted GDD dietary intakes and whether this prediction varied according to age, sex, region, and time. Calibration equations were developed to adjust FAO estimates to approximate national dietary surveys validated by using randomly split data sets. Results: For most food groups, FAO estimates substantially overestimated individual-based dietary intakes by 74.5% (vegetables) and 270% (whole grains) while underestimating beans and legumes (−50%) and nuts and seeds (−29%) (P < 0.05 for each). In multivariate regressions, these overestimations and underestimations for each dietary factor further varied by age, sex, region, and time (P < 0.001 for each). Split–data set calibration models, which accounted for country-level covariates and other sources of heterogeneity, effectively adjusted FAO estimates to approximate estimates from national survey data (r = 0.47–0.80) with small SEs of prediction (generally 1–5 g/d). Conclusions: For all food groups and total energy, FAO estimates substantially exceeded or underestimated individual-based national surveys of individual intakes with significant variation depending on age, sex, region, and time. Calibration models effectively adjusted the comprehensive, widely accessible FAO data to facilitate a more-accurate estimation of individual-level dietary intakes nationally and by age and sex.
