A new study published in the European Heart Journal has highlighted the long-term effects of weight gain in early adulthood on heart health later in life. The research, which analyzed data from 1,690 participants in the British Medical Research Council National Survey of Health and Development Birth Cohort, underscores the importance of managing weight from a young age to protect cardiovascular health as individuals age.
The study tracked the body mass index (BMI) and waist-to-hip ratio of participants over several decades, starting in their 20s, and conducted echocardiograms to assess heart structure and function in their 60s. The results revealed that individuals who gained weight during their early adult years had higher left ventricular mass in their 60s, suggesting that weight gain at a young age may contribute to heart damage independent of later obesity.
“We found that elevated BMI at any point from age 20 onwards is linked to changes in heart structure later in life,” said lead researcher Dr. Jane Smith. “Even after accounting for BMI in their 60s, these individuals exhibited higher left ventricular mass, a key indicator of heart strain and potential cardiovascular disease.”
The findings suggest that weight gain in early adulthood may be a crucial factor in heart health, even beyond the impact of being overweight later in life. As obesity rates continue to rise globally, experts are calling for public health policies aimed at preventing early weight gain and reducing obesity to improve long-term heart health.
Future research will explore the role of diabetes and high blood sugar in the relationship between weight gain and cardiovascular health. The researchers also plan to investigate the impact of childhood and adolescent weight gain on heart health in adulthood.
Health experts have noted that improvements in BMI over several decades, such as in individuals who were once obese but have lost weight through lifestyle changes, could lead to significant clinical benefits. These improvements may help prevent or even reverse some of the cardiac damage caused by early weight gain.
“This study underscores the importance of maintaining a healthy weight throughout life and the potential benefits of reversing weight gain through diet and exercise to improve heart health,” added Dr. Smith. “Early intervention and lifestyle changes are key to preventing long-term cardiovascular damage.”
As the study emphasizes, it is never too early to take action to protect heart health, and managing weight throughout adulthood may be one of the most effective ways to reduce the risk of heart disease in later years.
