饮食多样性被认为是高质量饮食的关键要素。然而，提供更多种类的能量密集食物的饮食可能会增加食物摄入量和体重。本研究的目的是探讨斯里兰卡成年人饮食多样性与肥胖的关系。采用多阶段分层抽样方法随机抽取600名18岁以上的成年人。通过24小时饮食回忆进行饮食摄入评估。计算三种膳食评分，即膳食多样性评分（DDS）、膳食多样性评分（DDSP）和食物多样性评分（FVS）。体重指数（BMI）≥ 25 kg.m-2定义为肥胖，亚洲腰围临界值用于诊断腹型肥胖。男性和女性的DDS平均值分别为6.23和6.50（p=0.06），而DDSP分别为3.26和3.17（p=0.24）。男性和女性之间的FVS值有显著差异9.55和10.24（p=0.002）。斯里兰卡成年人的饮食多样性与性别、居住地、种族、教育水平显著相关，但与糖尿病状况无关。随着饮食分数的增加，除了淀粉外，大多数食物组的消耗百分比都增加了。与非肥胖组相比，肥胖和腹型肥胖成人具有最高的DDS（p<0.05）。随着膳食多样性的增加，该人群的BMI、腰围和能量消耗水平显著增加。我们的数据表明，饮食多样性与斯里兰卡成年人的几个社会人口特征和肥胖呈正相关。虽然人们广泛推荐高度的饮食多样性，但公共卫生信息应强调在选择性食物中改善饮食多样性。
Dietary diversity is recognized as a key element of a high quality diet. However, diets that offer a greater variety of energy-dense foods could increase food intake and body weight. The aim of this study was to explore association of diet diversity with obesity in Sri Lankan adults. Six hundred adults aged > 18 years were randomly selected by using multi-stage stratified sample. Dietary intake assessment was undertaken by a 24 hour dietary recall. Three dietary scores, Dietary Diversity Score (DDS), Dietary Diversity Score with Portions (DDSP) and Food Variety Score (FVS) were calculated. Body mass index (BMI) ≥ 25 kg.m-2 is defined as obese and Asian waist circumference cut-offs were used diagnosed abdominal obesity. Mean of DDS for men and women were 6.23 and 6.50 (p=0.06), while DDSP was 3.26 and 3.17 respectively (p=0.24). FVS values were significantly different between men and women 9.55 and 10.24 (p=0.002). Dietary diversity among Sri Lankan adults was significantly associated with gender, residency, ethnicity, education level but not with diabetes status. As dietary scores increased, the percentage consumption was increased in most of food groups except starches. Obese and abdominal obese adults had the highest DDS compared to non obese groups (p<0.05). With increased dietary diversity the level of BMI, waist circumference and energy consumption was significantly increased in this population. Our data suggests that dietary diversity is positively associated with several socio-demographic characteristics and obesity among Sri Lankan adults. Although high dietary diversity is widely recommended, public health messages should emphasize to improve dietary diversity in selective food items.
