Anemia and obesity are health problems in Sudan. Data on the association between obesity and anemia in adults are scarce. We aimed to investigate the prevalence of anemia and its association with body mass index (BMI) and obesity among adults in Sudan.
A community-based survey was conducted in northern Sudan. The participants' sociodemographic characteristics were assessed using a questionnaire. Multivariate binary analyses were performed.
Out of 405 adults, there were 204 (50.4%) males and 201 (49.6%) females. Their median (IQR) of age and BMI was 45.0 (33.0‒55.5) y and 26.2 (22.5‒30.4) kg/m2, respectively. Thirty-nine (9.6%), 131 (32.3%), 122 (30.1%) and 113 (27.9%) were underweight, normal weight, overweight and obese, respectively. Ninety-three (23.0%) had anemia and one (0.2%) had severe anemia. BMI values in adults with anemia were significantly lower than those without anemia. In a multivariate binary analysis, increasing BMI (adjusted OR [AOR]=0.94, 95% CI 0.90 to 0.98) and obesity (AOR=0.39, 95% CI 0.20 to 0.76) were associated with a lower risk of anemia.
Increasing BMI and obesity were associated with a lower risk of anemia. Further research is needed to explore the association between obesity and anemia.
贫血和肥胖是苏丹的健康问题。关于成年人肥胖与贫血之间关联的数据稀缺。我们旨在调查苏丹成年人中贫血的患病率及其与体重指数（BMI）和肥胖的关联。
在苏丹北部进行了一项基于社区的调查。使用问卷评估参与者的社会人口学特征。进行了多变量二元分析。
在405名成年人中，有204名（50.4%）男性和201名（49.6%）女性。他们的年龄中位数（四分位间距）和BMI分别为45.0（33.0 - 55.5）岁和26.2（22.5 - 30.4）kg/m²。体重过轻、正常体重、超重和肥胖的分别有39名（9.6%）、131名（32.3%）、122名（30.1%）和113名（27.9%）。93名（23.0%）患有贫血，1名（0.2%）患有严重贫血。贫血成年人的BMI值显著低于无贫血者。在多变量二元分析中，BMI增加（调整后比值比[AOR]=0.94，95%置信区间0.90至0.98）和肥胖（AOR=0.39，95%置信区间0.20至0.76）与贫血风险较低相关。
BMI增加和肥胖与贫血风险较低相关。需要进一步研究以探索肥胖与贫血之间的关联。
