A recent study has found that cholesterol and blood pressure levels in obese adults aged 40 and over have become increasingly similar to those of individuals with a healthy weight. This shift contrasts with earlier trends when obese adults were more likely to exhibit elevated blood pressure and unhealthy cholesterol levels.

Researchers attribute this change primarily to the widespread use of medications that lower cholesterol and blood pressure, such as statins and antihypertensive drugs. These medications are more frequently prescribed to people with obesity, contributing to a narrowing, or in some cases disappearance, of differences in cardiovascular risk factors between obese and normal-weight individuals in middle-aged and older populations.

Professor Majid Ezzati of Imperial College London, who led the study, explained that in high-income countries, the use of these medications has helped reduce cardiovascular risks among middle-aged and older adults to levels comparable to those seen in people with a normal body mass index (BMI). He noted that the findings offer valuable insights into the cardiovascular health of individuals likely to be prescribed weight loss drugs, which have seen a sharp rise in use.

The study observed a marked decline in unhealthy cholesterol and blood pressure readings over time, particularly among adults over 40. This trend has led to a convergence of these risk factors between obese and normal-weight groups in older age brackets. However, the research also highlighted a persistent disparity among younger adults under 40, where individuals with obesity still show higher levels of bad cholesterol and elevated blood pressure compared to their normal-weight peers.

Co-author Yse d’Ailhaud de Brisis emphasized that although the findings are encouraging for older adults with obesity, younger adults with obesity continue to face greater cardiovascular health risks than those with normal BMI. The study underscores the ongoing challenges in addressing cardiovascular risk factors among younger populations with obesity, despite medical advances in the management of these conditions among older adults.
