黑人糖尿病高發的因果關係研究

新冠的兩大危險因素肥胖和糖尿病

黑人這兩個疾病都是高發病率

肥胖在非裔美國人中高發病率的歸因研究非常多。生物學，個體行為，社會環境，經濟地位都有交互作用。基本沒有結論是·黑人的肥胖是找因為“不平等”的因素。

在美國黑人的糖尿病發病率的歸因分析，結論是生物學因素（肥胖）是主要促因。

The researchers used statistical analyses to determine how biological, neighborhood, psychosocial, socioeconomic, and behavioral risk factors contributed to rates of diabetes. They found that biological risk factors accounted for most of the health disparity. These factors included a combination of body mass index, waist measurement, fasting glucose levels, lipids, blood pressure, and lung function. Differences between blacks and whites in neighborhood, psychosocial, socioeconomic, and behavioral factors were also linked with diabetes, although to a lesser degree.

“Obesity is driving these differences,” Carnethon says. “The findings surprised us, because for the past 20 years there was a narrative that there must be something we haven’t found that was causing this higher rate.... We now know there is no mystery to these higher rates. Our efforts to control the traditional risk factors can work to reduce the disparities we observe in diabetes incidence.”
