Abstract

Obesity prevalence in the United States has increased drastically in the last two decades. Racial differences in obesity have emerged with the increase in obesity, with temporal trends because of individual, socioeconomic, and environmental factors, eating behaviors, lack of exercise, etc., raising questions about understanding the mechanisms driving these racial differences in the prevalence of obesity among non-Hispanic Black (NHB) and non-Hispanic White (NHW) men. Although many studies have measured obesity using body mass index (BMI), little is known about waist circumference (WC). This study examines variations in obesity among NHW and NHB using BMI and WC. We used National Health and Nutrition Examination Surveys (1999-2016) with a sample of 9,000 NHW and 3,913 NHB men aged 20 years or older. To estimate the association between the prevalence of obesity (BMI ≥30) and race, we applied modified Poisson regression; to explore and decompose racial differences, we used Oaxaca-Blinder decomposition (OBD). We found that NHW had higher abdominal obesity (WC ≥102) than NHB, but NHB were more likely to be obese (BMI ≥30) during most years, with some fluctuations. Modified Poisson regression showed that NHB had a higher prevalence of obesity (prevalence ratio [PR]: 1.11, 95% confidence interval [CI] = [1.04, 1.18]) but lower abdominal obesity (PR: 0.845; 95% CI = [0.801, 0.892]) than NHW. OBD showed that age, access to health care, smoking, and drinking contributed to the differences in abdominal obesity. The study identifies a significant increase in obesity among men over the last two decades; generalized obesity (based on BMI) was more problematic for NHB men, but abdominal obesity was more problematic for NHW men.

测量20岁或以上非西班牙裔黑人和白人男性肥胖危险因素的种族差异。
在过去的二十年里,美国的肥胖率急剧上升。肥胖的种族差异随着肥胖的增加而出现,其时间趋势是由个体、社会经济和环境因素、饮食行为、缺乏锻炼等因素造成的,这就提出了关于理解非西班牙裔黑人(NHB)和非西班牙裔白人(NHW)男性肥胖患病率的种族差异的机制的问题。虽然许多研究都用身体质量指数(BMI)来衡量肥胖,但对腰围(WC)却知之甚少。本研究使用BMI和WC检测了非高脂肪人群和非高脂肪人群在肥胖方面的差异。我们使用国家健康和营养检查调查(1999-2016),样本为9000名20岁或以上的NHW和3913名NHB男性。为了估计肥胖患病率(BMI≥30)与种族之间的关系,我们应用了修正泊松回归;为了探索和分解种族差异,我们使用了Oaxaca-Blinder分解(OBD)。我们发现,NHW的腹部肥胖(BMI≥102)高于NHB,但NHB在大多数年份更容易肥胖(BMI≥30),并有一定的波动。修正泊松回归显示,NHB组肥胖患病率较高(患病率比[PR]: 1.11, 95%可信区间[CI] =[1.04, 1.18]),但下腹部肥胖患病率较高(PR: 0.845;95% CI =[0.801, 0.892])高于NHW。OBD显示,年龄、获得医疗保健的机会、吸烟和饮酒导致了腹部肥胖的差异。该研究发现,在过去20年里,男性肥胖人数显著增加;全身性肥胖(基于BMI)在NHB男性中更成问题,但腹部肥胖在NHW男性中更成问题。
