Differing ethnic risks of obesity explained

For many years it has been believed that black individuals have a higher risk of developing diabetes, and the reason for this was unexplained. However, a new study published in JAMA has concluded that rates of obesity are what drives the differences in diabetes incidence between black and white individuals. Data from 4,251 individuals enrolled in a separate study was used for this research, spanning a range of states within the USA. Previous studies have found that higher rates of diabetes are present in black populations even when risk factors such as obesity and socioeconomic status are taken into account. Many of these studies measured parameters such as obesity, physical activity, and diet once during their participants’ lives. This study found that the black population tended to gain more weight over time, thereby increasing their risk of developing diabetes.

There will be no easy fix for this complex issue as it involves a variety of biological, socioeconomic, cultural, and behavioural factors. The study authors explained that it is vital for there to be equal access to healthy foods, spaces for physical activity, and economic opportunity to afford these things. If we were to control these risk factors we may go some way to controlling the effects of obesity, such as diabetes.
