黑人糖尿病高发的因果关系研究

新冠的两大危险因素肥胖和糖尿病

黑人这两个疾病都是高发病率

肥胖在非裔美国人中高发病率的归因研究非常多。生物学，个体行为，社会环境，经济地位都有交互作用。基本没有结论是·黑人的肥胖是找因为“不平等”的因素。

在美国黑人的糖尿病发病率的归因分析，结论是生物学因素（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.”
