Mental Health: Adults with Depression More Likely to Develop Heart Problems, Says Study

According to a recent study, researchers found that examined data from more than 500,000 people between the ages of 18 and 49, young adults who experience sadness or depression are more likely to develop cardiovascular disease (CVD) and have poor heart health. The findings support a growing body of research linking CVD with depression in young and middle-aged individuals and imply the relationship may start in adolescence. The study, published in the Journal of the American Heart Association, also found that young adults who self-reported feeling depressed or having poor mental health days had higher rates of heart attacks, strokes, and risk factors for heart disease compared with their peers without mental health issues.

"When you're stressed, anxious, or depressed, you may feel overwhelmed, and your heart rate and blood pressure rise. It's also common that feeling down could lead to making poor lifestyle choices like smoking, drinking alcohol, sleeping less, and not being physically active - all adverse conditions that negatively impact your heart," says Garima Sharma, M.B.B.S., associate professor of medicine at Johns Hopkins Medicine and senior author of the study.

Sharma and her colleagues looked at data from 593,616 adults who participated in the Behavioral Risk Factor Surveillance System, a self-reported, nationally representative survey conducted between 2017 and 2020. The survey included questions about whether they have ever been told they have a depressive disorder, how many days they experienced poor mental health in the past month (0 days, 1-13 days or 14-30 days), whether they had experienced a heart attack, stroke or chest pain, and if they had cardiovascular disease risk factors.

Risk factors include high blood pressure, high cholesterol, being overweight/obese, smoking, diabetes, and poor physical activity and diet. People who had two or more of these risk factors were considered to have suboptimal cardiovascular health. One in five adults self-reported having depression or frequently feeling low, with the study noting that there could have been higher rates during the last year of the study, which was the first year of the COVID-19 pandemic. According to the U.S. Centers for Disease Control and Prevention, the percentage of U.S. adults who experienced depression or anxiety jumped from 36.4% to 41.5% during the first year of the pandemic, with the highest spike among people ages 18 to 29.

The study revealed that, overall, those who self-reported several days of feeling down had a stronger link to cardiovascular disease and poor heart health. Compared with people who reported no poor mental health days in the past 30 days, participants who reported up to 13 poor mental health days had 1.5 times higher odds of CVD, while those with 14 or more days of poor mental health had double the odds. Associations between poor mental health and CVD did not differ significantly by gender or urban/rural status."The relationship between depression and heart disease is a two-way street. Depression increases your risk of heart issues, and those with heart disease experience depression," says Yaa Adoma Kwapong, M.D., M.P.H., a postdoctoral research fellow at Johns Hopkins Ciccarone Center for the Prevention of Cardiovascular Disease and lead author of the study. "Our study suggests that we need to prioritize mental health among young adults and perhaps increase screening and monitoring for heart disease in people with mental health conditions and vice versa to improve overall heart health."
