A new study published in the Annals of Internal Medicine has found a strong connection between income levels and the risk of developing major health problems such as high blood pressure, diabetes, and obesity in middle-aged adults.
The research was led by scientists from Beth Israel Deaconess Medical Center and Harvard Medical School.
The study looked at data from over 20,000 adults aged 40 to 64, collected between 1999 and March 2020 through the National Health and Nutrition Examination Survey (NHANES).
Researchers wanted to see how income levels affected the presence and control of major cardiovascular risk factors—especially high blood pressure (hypertension), diabetes, and obesity.
What they discovered was both revealing and concerning. Adults with lower incomes were more likely to have high blood pressure. By the year 2020, nearly 45% of low-income adults had been diagnosed with hypertension. Interestingly, their rates of diabetes and obesity stayed relatively steady during the study period.
In contrast, people with higher incomes did not see an increase in high blood pressure, but they did show rising rates of diabetes and obesity. By 2020, 44% of middle-aged adults in the higher-income group were diagnosed with obesity.
These differences remained even after researchers accounted for other important factors such as health insurance, access to medical care, and whether the participants had enough healthy food to eat. This means that income itself—regardless of these other issues—plays a big role in who develops certain health problems.
The study emphasizes the urgent need to understand how income and other social conditions affect health. Poorer adults are at higher risk for long-term problems caused by high blood pressure, which can lead to heart attacks, strokes, and kidney disease.
Meanwhile, wealthier adults face growing risks from rising rates of obesity and diabetes, which can also lead to serious complications.
One reason why this study matters so much is that progress in reducing deaths from heart disease has slowed down in the past 10 years in the U.S. In fact, deaths from heart problems have even increased among middle-aged adults during this time. So, learning how income affects health is more important than ever.
The study’s authors suggest that improving health means looking beyond just medical care. It involves creating fairer, healthier communities. That might include better support systems, public health campaigns, and early education about nutrition and exercise.
Families, schools, and community leaders can all help by creating supportive environments, reducing stress, and making healthy food and exercise options more accessible. This is especially important for children, as early experiences can shape health later in life.
In summary, the study shows that income levels affect which health risks are most common in middle-aged adults. Lower-income individuals are more affected by high blood pressure, while higher-income adults are more likely to struggle with diabetes and obesity.
Understanding these patterns is key to creating better health outcomes for everyone, regardless of their income.
If you’re concerned about blood pressure, research has shown that some everyday habits—like drinking too much coffee—can increase your risk. On the other hand, eating more plant-based foods and practicing early time-restricted eating may help improve blood pressure.
The research findings were published in the Annals of Internal Medicine.
