Racial disparities in obesity among men are accompanied by positive associations between income and obesity among Black men only. Race also moderates the positive association between marital status and obesity. This study sought to determine how race, income, and marital status interact on obesity among men. Using data from the 2007 to 2014 National Health and Nutrition Examination Survey, obesity was measured as body mass index ≥30 kg/m among 6,145 Black and White men. Income was measured by percentage of the federal poverty line and marital status was categorized as currently, formerly, or never married. Using logistic regression and interaction terms, the associations between income and obesity were assessed by race and marital status categories adjusted for covariates. Black compared to White (OR = 1.19, 95% CI [1.03, 1.38]), currently married compared to never married (OR = 1.45, 95% CI [1.24, 1.69]), and high-income men compared to low income men (OR = 1.26, 95% CI [1.06, 1.50]) had higher odds of obesity. A three-way interaction was significant and analyses identified that income was positively associated with obesity among currently married Black men and never married White men with the highest and lowest probabilities of obesity, respectively. High-income, currently married Black men had higher obesity rates and may be at increased risk for obesity-related morbidities.
男性肥胖中的种族差异伴随着黑人群体中收入与肥胖之间的正相关关系，而这种正相关关系仅存在于黑人群体中。种族也调节了婚姻状况与肥胖之间的正相关关系。本研究旨在确定种族、收入和婚姻状况如何相互作用影响男性肥胖。使用 2007 年至 2014 年全国健康与营养调查的数据，将 BMI≥30kg/m²的肥胖定义为 6145 名黑人和白人男性。收入用联邦贫困线的百分比来衡量，婚姻状况分为当前、以前或从未结婚。通过逻辑回归和交互项，调整了协变量后，按种族和婚姻状况类别评估了收入与肥胖之间的关联。与白人相比，黑人（OR=1.19，95%CI[1.03,1.38]）、当前已婚者（OR=1.45，95%CI[1.24,1.69]）和高收入者（OR=1.26，95%CI[1.06,1.50]）肥胖的可能性更高。三方交互作用具有统计学意义，分析结果表明，在当前已婚的黑人男性和从未结婚的白人男性中，收入与肥胖呈正相关，这两个群体分别是肥胖可能性最高和最低的群体。高收入、当前已婚的黑人男性肥胖率更高，可能面临更高的肥胖相关疾病风险。
