Living in a food-insecure or food insufficient household may increase risk for binge eating and obesity. Because racial disparities in food access, obesity, and access to treatment for disordered eating exist, it is important to examine these relationships in Black populations.
We conducted a secondary analysis of data from the National Survey of American Life (N = 4553), a nationally-representative sample of Black Americans, including African Americans and Afro-Caribbeans. Logistic regression was used to explore the association of food insufficiency with obesity and binge eating.
In the total sample of Black Americans, the prevalence of food insufficiency was 10.9% (95% CI 10.0-11.8%). Food insufficiency was not significantly associated with obesity in Black Americans, but when associations were explored in analyses stratified by ethnicity and sex, food insufficiency significantly predicted an increased odds of obesity in Afro-Caribbeans (odds ratio [OR] = 1.47, 95% CI 1.01, 2.13). Individuals experiencing food insufficiency were more likely to report recurrent binge eating in the last 12 months (3% v 2%, P = 0.02) and a lifetime history of binge eating (6% v 3%, P = 0.004) compared to those who were food sufficient. After adjusting for socio-demographic factors, food insufficiency was not significantly associated with recurrent binge eating in Black Americans or in sex- and ethnicity-stratified analyses.
The present study reveals a more complex relation between food insufficiency and binge eating than previously thought-although an association existed, it was attenuated by an array of sociodemographic factors. Our results also underscore the importance of considering ethnicity as different patterns emerged between African American and Afro-Caribbean participants.
生活在粮食不安全或食物不足的家庭中可能会增加暴饮暴食和肥胖的风险。由于在食物获取、肥胖以及饮食失调治疗的可及性方面存在种族差异，因此在黑人人群中研究这些关系很重要。
我们对美国生活全国调查（N = 4553）的数据进行了二次分析，该调查是美国黑人（包括非裔美国人和非洲裔加勒比人）具有全国代表性的样本。采用逻辑回归来探讨食物不足与肥胖及暴饮暴食之间的关联。
在美国黑人总样本中，食物不足的患病率为10.9%（95%置信区间10.0 - 11.8%）。在美国黑人中，食物不足与肥胖无显著关联，但在按种族和性别分层的分析中探讨关联时，食物不足显著预测非洲裔加勒比人肥胖几率增加（优势比[OR] = 1.47，95%置信区间1.01，2.13）。与食物充足的个体相比，经历食物不足的个体在过去12个月中更有可能报告反复暴饮暴食（3%对2%，P = 0.02）以及有暴饮暴食的终生史（6%对3%，P = 0.004）。在调整社会人口学因素后，在美国黑人或按性别和种族分层的分析中，食物不足与反复暴饮暴食无显著关联。
本研究揭示了食物不足与暴饮暴食之间的关系比先前认为的更为复杂——尽管存在关联，但一系列社会人口学因素减弱了这种关联。我们的结果还强调了考虑种族的重要性，因为非裔美国人和非洲裔加勒比参与者之间出现了不同模式。
