Dietary diversity score (DDS) is known as an indicator of food quality. Dietary diversity can promote health status. The aim of this study was determined DDS and its related factors in Kermanshah University of Medical Sciences (KUMS) employees. This cross-sectional study was conducted on 190 employees of KUMS in 2015. According to the population of KUMS centers which were selected randomly (Paramedical, Public Health faculties, Imam Reza Hospital and province health center), subjects were selected by convenience sampling method. Food frequency questionnaire (FFQ) was used to calculate DDS. Foods were divided into 5 main groups: grains, vegetables, fruits, meat, and dairy products. The main groups had 23 subgroups. Total DDS divided to 4 quartiles: less than 3.0, 3.0-5.5, 5.6-8.5, and more than 8.5. Anthropometric parameters including: weight, height, waist circumference (WC), and hip circumference were measured. Data were analyzed by Kolmogorov-Smirnov test, χ test, and analysis of variance (ANOVA) test with SPSS 20 software (IBM Corp., Chicago, IL, USA). The mean ± standard deviation of DDS and body mass index (BMI) were 5.68 ± 1.73 and 25.1 ± 3.42 kg/m, respectively. The average of the waist-to-hip ratio (WHR) in men and women was 0.92 ± 0.04 and 0.86 ± 0.06, respectively. There was statistically significant difference between DDS and self-reported economic status (p < 0.022). No significant difference was observed between DDS and BMI or WC. However, significant negative correlation was observed between DDS and WHR in men (p < 0.019). This study showed that DDS had a negative correlation with the WHR. Therefore, dietary diversity may improve health status by effect on fat distribution in body.
饮食多样性评分（DDS）是食物质量的一个指标。饮食多样性能够促进健康状况。本研究的目的是确定克尔曼沙赫医科大学（KUMS）员工的饮食多样性评分及其相关因素。这项横断面研究于2015年对190名KUMS员工进行。根据随机选取的KUMS中心（辅助医疗、公共卫生学院、伊玛目礼萨医院和省卫生中心）的人员，采用方便抽样法选取研究对象。使用食物频率问卷（FFQ）来计算饮食多样性评分。食物分为5个主要类别：谷物、蔬菜、水果、肉类和乳制品。这些主要类别又分为23个子类别。总饮食多样性评分分为4个四分位数：低于3.0、3.0 - 5.5、5.6 - 8.5以及高于8.5。测量了人体测量参数，包括体重、身高、腰围（WC）和臀围。使用SPSS 20软件（美国伊利诺伊州芝加哥市IBM公司）通过柯尔莫哥洛夫 - 斯米尔诺夫检验、χ检验和方差分析（ANOVA）对数据进行分析。饮食多样性评分和体重指数（BMI）的平均值±标准差分别为5.68±1.73和25.1±3.42 kg/m²。男性和女性的腰臀比（WHR）平均值分别为0.92±0.04和0.86±0.06。饮食多样性评分与自我报告的经济状况之间存在统计学显著差异（p < 0.022）。在饮食多样性评分与BMI或腰围之间未观察到显著差异。然而，在男性中饮食多样性评分与腰臀比之间观察到显著的负相关（p < 0.019）。本研究表明饮食多样性评分与腰臀比呈负相关。因此，饮食多样性可能通过影响体内脂肪分布来改善健康状况。
