目的：本研究评估是否一个简单的食物项目和食物组的计数可以预测在一个经济贫困的国家的饮食的营养充足性。设计：一个为期三天的称重记录的儿童。设置：库蒂亚拉镇，在东南邮件。主题：77名儿童，13-58个月的年龄。一名儿童因食物种类特别少而被排除在外。干预：这项研究于1995年4月至8月进行。这项研究的数据被用来创建两个不同的指数：食物品种评分（FVS），一个简单的食物项目计数，和饮食多样性评分（DDS），一个食物组计数。计算平均营养比（MAR）作为营养充足性的指标，并用于验证FVS和DDS。FVS为20.5（3.8），平均（s.d.）DDS为5.8（1.1）。FVS与MAR呈正相关（Pearson 0.33，P < 0.001），DDS与MAR呈正相关（Pearson 0.39，P < 0.001）。FVS的临界点为23，DDS为6，这些指数具有很高的能力来识别那些营养不足的饮食。MAR随FVS和DDS的增加而增加。FVS至少需要15或DDS至少5给一个令人满意的MAR.Conclusion：虽然一个简单的计数的食物项目或食物组不能给一个完整的图片的营养摄入量的充足性，从这项研究的结果表明，食物评分可以给一个相当好的评估饮食的营养充足性，特别是如果结合。这些指标对于在人们通常共用一个碗吃饭的地区确定弱势群体非常重要，这使得详细的饮食摄入量研究变得困难、耗时和昂贵。
Objective: This study assesses whether a simple count of food items and food groups can predict the nutritional adequacy of the diet in an economically poor country.Design: A three-day weighed record of children.Setting: Koutiala town, in Southeastern Mail.Subjects: Seventy-seven children, 13-58 months of age. One child was excluded owing to an extraordinarily low food variety.Intervention: The study was conducted in April-August 1995. Data from this study were used to create two different indices: Food Variety Score (FVS), a simple count of food items, and Dietary Diversity Score (DDS), a count of food groups. Mean Adequacy Ratio (MAR) was calculated as an indicator for nutrient adequacy, and used to validate FVS and DDS.Results: Mean (s.d.) FVS was 20.5 (3.8) and mean (s.d.) DDS was 5.8 (1.1). A positive correlation was found both between FVS and MAR (Pearson 0.33, P < 0.001) and DDS and MAR (Pearson 0.39, P < 0.001). With cutoff points for FVS at 23 and for DDS at 6, the indices have high ability to identify those with a nutritionally inadequate diet. MAR increased with increasing FVS and DDS. FVS needs to be at least 15 or DDS at least 5 to give a satisfactory MAR.Conclusion: Although a simple count of food items or food groups cannot give a full picture of the adequacy of the nutrient intake, the results from this study show that the food scores can give a fairly good assessment of the nutritional adequacy of the diet, particularly if combined. Such indicators are important for identification of vulnerable groups in areas where people normally eat from a shared bowl, which makes detailed dietary intake studies difficult, time consuming and expensive.
