隐匿性阴茎合并肥胖的患儿体成分指标对其疾病影响

Influence of Body Composition Index on Concealed Penis Occurrence in Obese Children

摘要: 目的：探究肥胖合并隐匿性阴茎患儿体成分指标中是否有隐匿发生的危险因素。方法：以2021年10月~2022年7月就诊于我院的25名肥胖合并隐匿性阴茎，并在营养科干预下体重和隐匿症状都有改善的患儿为研究组，以同时期25例体重正常，无隐匿性阴茎的患儿为对照组，分析体成分指标中导致患儿隐匿发生的危险因素。结果：1) 对50例研究对象进行spearman秩相关分析，显示阴茎外观长度与BMI、腰臀比、骨骼肌、体脂量、耻骨联合前脂肪厚度成负相关，与肌肉量成正相关。耻骨联合前脂肪厚度，与肌肉量成负相关，与其余指标成正相关。2) 单因素分析中BMI、耻骨联合前脂肪厚度、腰臀比、骨骼肌、体脂量是发生隐匿的危险因素(P < 0.05)，差异有统计学意义。肌肉量亦有差异，但差异不够显著。多因素logistic回归分析显示，BMI (P = 0.033, OR = 3.310)、腰臀比(P = 0.027, OR = 1.360)为发生隐匿的危险因素。结论：在肥胖的儿童中，过高的BMI和腰臀比是造成隐匿性阴茎的危险因素。

Abstract: Objective: To explore whether there are hidden risk factors in body composition index of obese children with concealed penis. Methods: A total of 25 obese children with concealed penis who were admitted to our hospital from October 2021 to July 2022 and whose weight and occult symptoms improved under the intervention of the nutrition department were selected as the study group, and 25 children with normal weight and noconcealed penis were selected as the control group. Body composition indicators which are the risk factors for concealed penis are analyzed. Results: 1) Spearman rank correlation analysis was performed on 50 subjects, which showed that penis ap-pearance length was negatively correlated with BMI, waist-hip ratio, skeletal muscle, body fat mass, and prepubic fat thickness, and positively correlated with muscle mass. Prepubic fat thickness was negatively correlated with muscle mass, and positively correlated with other indexes. 2) In univari-ate analysis, BMI, prepubic symphysis fat thickness, waist-hip ratio, skeletal muscle mass and body fat mass were the risk factors for concealed penis, P < 0.05, the difference was statistically signifi-cant. There were also differences in muscle mass, but the differences were not significant enough. Multivariate logistic regression analysis showed that BMI (P = 0.033, OR = 3.310) and waist-to-hip ratio (P = 0.027, OR = 1.360) were the risk factors for concealed penis. Conclusion: In obese children, high BMI and waist-to-hip ratio are risk factors for a concealed penis.
