To explore the relationship between body mass index (BMI ) and the severity of tic disorders (TDs) in children 6–14 years old. A total of 86 children diagnosed with TDs in a hospital between Jan. 2023 and Sept. 2023 were collected by convenient sampling method, and the general data and TD-specific data were collected and analyzed. Univariate analysis showed that patients with different Yale Global Tic Severity Scale (YGTSS) grades had statistically significant differences in age, BMI, residence, snacking pattern, weekly physical exercise frequency, weekly physical exercise time, and proportion of cesarean birth. Multiple linear regression analysis showed that the YGTSS score grades were related to BMI, snacking pattern, and cesarean birth of the patients. Correlation analysis revealed a positive correlation between BMI grades and the YGTSS score grades, with a higher BMI indicating more severe TDs. Predictive value evaluation showed that BMI, snacking pattern, and cesarean birth had predictive values for TD severity, and the highest value was found in the combined prediction. BMI, snacking pattern, and cesarean birth are of predictive values for the severity of TDs. In addition, BMI is positively correlated with the severity of TDs, and a higher BMI suggests more severe TDs.

学龄儿童体重指数与抽动障碍之​​间的关联

探讨 6-14 岁儿童体重指数 (BMI) 与抽动障碍 (TD) 严重程度之间的关系。采用便捷抽样方法收集2023年1月至2023年9月某医院诊断为TD的86例儿童，对一般数据和TD特异性数据进行收集和分析。单因素分析显示，不同耶鲁全球抽动严重程度量表（YGTSS）分级的患者在年龄、BMI、居住地、零食模式、每周体育锻炼频率、每周体育锻炼时间、剖宫产比例等方面差异有统计学意义。多元线性回归分析显示，YGTSS评分等级与患者的BMI、零食模式和剖宫产相关。相关分析显示BMI等级与YGTSS评分等级呈正相关，BMI越高表明TD越严重。预测值评估显示，BMI、零食模式和剖腹产对 TD 严重程度具有预测价值，且联合预测值最高。 BMI、零食模式和剖腹产对于 TD 的严重程度具有预测价值。此外，BMI与TD的严重程度呈正相关，BMI越高表明TD越严重。
