Previous studies that have reported trends on abdominal obesity among US children were usually based on anthropometric assessments. However, little is known about the recent trends in central adiposity measures by DXA and abdominal obesity since 2011-2012.
A serial cross-sectional analysis of US population-weighted data among children from NHANES 2011 to 2018 was conducted.
Between 2011-2012 and 2017-2018, there was a relatively stable trend among children aged 8-19 years in trunk fat and trunk fat percentage. During the same time periods, there were no significant changes in prevalence of abdominal obesity by waist circumference (18.6 vs. 21.1%) among those aged 2-19 years, and abdominal obesity by WHtR (34.1 vs. 36.2%) among those aged 6-19 years. However, a significant increase trend among boys aged 2-19 years was found in prevalence of abdominal obesity by waist circumference (16.1-22.7%; = 0.004). For Mexican American youth and non-Hispanic Asian boys, there is a significant increase in mean trunk fat percentage and waist circumference.
Between 2011-2012 and 2017-2018, there have been no significant changes in central adiposity measured by DXA and prevalence of abdominal obesity among US children. Our study further supports that there is an urgent need to improve their lifestyle to reduce abdominal obesity for US children, especially for Mexican American youth and non-Hispanic Asian boys.
以往报告美国儿童腹部肥胖趋势的研究通常基于人体测量评估。然而,自2011 - 2012年以来,关于通过双能X线吸收法(DXA)测量的中心性肥胖指标和腹部肥胖的近期趋势知之甚少。
对2011年至2018年美国国家健康与营养检查调查(NHANES)中儿童的美国人口加权数据进行了系列横断面分析。
在2011 - 2012年至2017 - 2018年期间,8 - 19岁儿童的躯干脂肪和躯干脂肪百分比呈相对稳定趋势。在同一时期,2 - 19岁人群中,按腰围定义的腹部肥胖患病率(18.6%对21.1%)以及6 - 19岁人群中按腰高比(WHtR)定义的腹部肥胖患病率(34.1%对36.2%)均无显著变化。然而,发现2 - 19岁男孩中按腰围定义的腹部肥胖患病率有显著上升趋势(16.1% - 22.7%;P = 0.004)。对于墨西哥裔美国青少年和非西班牙裔亚洲男孩,平均躯干脂肪百分比和腰围有显著增加。
在2011 - 2012年至2017 - 2018年期间,美国儿童中通过DXA测量的中心性肥胖和腹部肥胖患病率没有显著变化。我们的研究进一步支持,美国儿童迫切需要改善生活方式以减少腹部肥胖,特别是墨西哥裔美国青少年和非西班牙裔亚洲男孩。
