From January 2019 to December 2021, overweight and obese children who visited in health outpatient Center of Hunan Children's Hospital were studied to explore and analyze the rate, related factors and patterns of multimorbidity of overweight and obesity-related diseases in children in Hunan Province. Univariate and multivariate logistic regression models were used to analyze the multimorbidity-related factors of overweight and obesity-related diseases in children. Association rules (apriori algorithm) were used to explore the multimorbidity patterns of overweight and obesity-related diseases in children. A total of 725 overweight and obese children were included in this study. The multimorbidity rate of overweight and obesity-related diseases in children was 46.07% (334/725). Age, waist circumference, the frequency of food consumption such as hamburgers and fries and adding meals before bedtime were multimorbidity-related factors of overweight and obesity-related diseases in children. The multimorbidity associated with nonalcoholic fatty liver disease (NAFLD) was relatively common. The patterns with the top three support degrees were "NAFLD+dyslipidemia","NAFLD+hypertension" and "NAFLD+hyperuricemia". The patterns with the top three confidence and elevation degrees were "Hypertension+dyslipidemia => NAFLD","Hyperuricemia => NAFLD" and "NAFLD+hypertension => dyslipidemia".
对2019年1月至2021年12月在湖南省儿童医院保健门诊就诊的超重肥胖儿童进行调查，分析湖南省儿童超重肥胖相关疾病共病率、共病关联因素及组合模式。采用logistic回归模型分析儿童超重肥胖相关疾病共病关联因素；关联规则（apriori算法）挖掘儿童超重肥胖相关疾病共病组合模式。本研究共纳入725例研究对象。儿童超重肥胖相关疾病共病率为46.07%（334/725）；年龄、腰围、吃薯条汉堡的频次以及睡前加餐为儿童超重肥胖相关疾病共病关联因素。与非酒精性脂肪肝（NAFLD）有关共病组合模式较为常见，其中支持度位于前三共病组合模式为“NAFLD+血脂异常”“NAFLD+血压偏高”和“NAFLD+高尿酸血症”，置信度和提升度位于前三共病组合模式为“血压偏高+血脂异常=>NAFLD”“高尿酸血症=>NAFLD”和“NAFLD+血压偏高=>血脂异常”。.
