Abstract

AIMS

Data about the influence of short-term lifestyle intervention in children with obesity on long-term follow-up body weight, adipokines and cardiometabolic risk parameters is scarce.

METHODS

In a subgroup of the LOGIC-trial (Long-term Effects of Lifestyle Intervention in Obesity and Genetic Influence in Children), we assessed anthropometry (BMI, BMI-SDS (Standard Deviation Score), adipokines (omentin-1, chemerin, leptin, adiponectin) and cardiometabolic risk parameters, (e.g. hsCRP) in children with overweight/obesity after 4 weeks of lifestyle intervention (n = 156, 14.0 ± 1.8 yrs) and after one year follow-up (n = 50). Data were compared to normal weight children (JuvenTUM school cohort; n = 152, 13.3 ± 0.7 yrs).

RESULTS

Short-term lifestyle intervention was associated with a significant reduction in BMI and BMI-SDS (p < 0.001), with significant reductions in hsCRP, leptin, and chemerin levels, and an increase in adiponectin and omentin-1 levels (p < 0.001 for all). After one year follow-up a significant reduction in BMI and BMI-SDS was observed in children from the LOGIC-trial (p < 0.001). Improvements in adiponectin (p = 0.025) and chemerin levels (p = 0.027) were seen in children with clear weight loss success (BMI-SDS reduction ≥ 0.2), whereas children with no or only mild weight loss success showed an increase in leptin levels (p < 0.001). An increase in omentin-1 levels was observed after 1 year independent of weight change (p < 0.001).

CONCLUSION

Effects of short-term weight reduction on mean BMI and BMI-SDS persist over one year. Improvements in omentin-1 levels were independent of short-term or long-term weight loss.

摘要

目的

关于肥胖儿童短期生活方式干预对长期随访体重、脂肪因子和心脏代谢风险参数影响的数据稀缺。

方法

在LOGIC试验（儿童肥胖生活方式干预的长期影响及遗传影响）的一个亚组中，我们评估了超重/肥胖儿童在生活方式干预4周后（n = 156，14.0 ± 1.8岁）和一年随访后（n = 50）的人体测量指标（BMI、BMI标准差评分）、脂肪因子（网膜素-1、趋化素、瘦素、脂联素）和心脏代谢风险参数（如高敏C反应蛋白）。数据与正常体重儿童（JuvenTUM学校队列；n = 152，13.3 ± 0.7岁）进行比较。

结果

短期生活方式干预与BMI和BMI标准差评分显著降低相关（p < 0.001），高敏C反应蛋白、瘦素和趋化素水平显著降低，脂联素和网膜素-1水平升高（所有p < 0.001）。一年随访后，LOGIC试验中的儿童BMI和BMI标准差评分显著降低（p < 0.001）。体重明显减轻成功（BMI标准差评分降低≥0.2）的儿童脂联素（p = 0.025）和趋化素水平有所改善（p = 0.027），而体重没有减轻或仅轻度减轻成功的儿童瘦素水平升高（p < 0.001）。一年后观察到网膜素-1水平升高，与体重变化无关（p < 0.001）。
