Background: Balanced and adequate nutrition is important to improve the quality of life of children with intellectual disability but most of these children are negatively affected by nutritional problems.

Objective: This study was conducted to determine the nutritional status and effect of the severity of intellectual disability on nutritional status of children and adolescents with intellectual disabilities.

Methods: One hundred twenty-two intellectually disabled children aged 4–18 years from five different special education and rehabilitation centers were included in the study. Their socio-demographic characteristics, body weight, height, body mass index (BMI), mid-upper arm circumference (MUAC), and skinfold thickness were examined, and their three-day food consumption record was taken.

Results: Anthropometric scores did not differ significantly according to the severity of intellectual disability. According to evaluations made based on the World Health Organization’s 2007 percentile curves, 61.4% of the subjects with mild intellectual disability (MID), 57.1% of those with moderate intellectual disability (MOID), and 53.3% of those with severe intellectual disability (SID) were within the normal BMI range for their age.

Conclusion: Rates of malnutrition and shortness in children and adolescents with SID were found to be higher than among children with MID and MOID, though the differences were not statistically significant.

背景：均衡和充足的营养对于改善智障儿童的生活质量很重要，但这些儿童中的大多数都受到营养问题的负面影响。

目的：本研究旨在确定智力障碍儿童青少年的营养状况以及智力障碍严重程度对营养状况的影响。

方法：来自五个不同特殊教育和康复中心的 122 名 4-18 岁智障儿童被纳入研究。检查了他们的社会人口学特征、体重、身高、体重指数 (BMI)、上臂中围 (MUAC) 和皮褶厚度，并记录了他们三天的食物消耗量。

结果：根据智力障碍的严重程度，人体测量分数没有显着差异。根据世界卫生组织2007年百分位曲线评估，轻度智障（MID）受试者占61.4%，中度智障（MOID）受试者占57.1%，重度智障（SID）受试者占53.3%。 ) 在他们年龄的正常 BMI 范围内。

结论：发现 SID 儿童和青少年的营养不良和矮小率高于 MID 和 MOID 儿童，但差异无统计学意义。
