目的 探讨睾丸容积超声检测的优越性 ;明确单纯肥胖与正常儿童睾丸发育之差异 ;分析Kaup指数变化对儿童睾丸发育可能产生的影响。方法 ①将超声测量三径并计算出睾丸容积均值 (MVT)的 6 18例 7～ 14岁的肥胖男童 ,按年龄分为 8个年龄段 ;同样方法检测相应年龄段正常男童 6 0 3例作为对照组 ,进行MVT测量结果的比较与评价 ;②另对两组中年龄段为 12岁、年龄差限制在 6个月以内、身高分组差值≤ 5cm各 5 1例 ,进行MVT 1∶1的配对资料比较及Kaup指数变化对MVT影响的分析。 结果 7～ 14岁各年龄段肥胖组与对照组MVT的对比结果均有极显著差异 (P <0 0 1)。两组 12岁男童MVT 1∶1配对资料比较结果仍有极显著性差异(P <0 0 1) ;对照组Kaup指数为 15～ 2 0 ,体重及身高增长同MVT发育有极显著的相关性 (P <0 0 1) ;而肥胖组Kaup指数 >2 0 ,上述的相关指标无显著意义 (P >0 0 5 )。结论 两组 7～ 14岁儿童MVT比较结果均有极显著差异。分析发现 ,由于两组Kaup指数的不同 ,而导致儿童身高及体重的增长与睾丸发育之间的相关关系的差异。因此 ,可能明显影响了肥胖儿童睾丸的发育。
Objective To explore the superiority of testicular volume ultrasound detection; to clarify the difference between simple obesity and normal children’s testicular development; and to analyze the possible influence of Kaup index on children’s testicular development. Methods①A total of 6 18 obese boys aged 7-14 years old with MVT were divided into 8 age groups according to their age. The same method was used to detect normal boys with corresponding ages As the control group, MVT measurement results were compared and evaluated; ② the other two groups were 12 years of age, the age difference within 6 months, the difference between the height group 5l 5l, MVT 1: 1 paired data comparison and Kaup index changes on the impact of MVT analysis. Results The results of MVT in obesity group and control group from 7 to 14 years of age were significantly different (P <0.01). There was still a significant difference (P <0.01) in MVT 1: 1 paired data between two groups of 12-year-old boys; Kaup index was 15-20 in the control group, and there was a significant correlation between weight and height growth and MVT development (P <0.01). However, the Kaup index of obesity group was> 20, there was no significant correlation between the above indexes (P> 0.05). Conclusion The results of MVT between two groups of 7-14-year-old children have extremely significant differences. The analysis found differences in the correlation between height and weight gain and testicular development in children due to differences in Kaup index between the two groups. Therefore, the development of testicles may be significantly affected in obese children.
