Health Anxiety May Increase Risk of Heart Disease, Research Finds

An anonymous reader quotes a report from The Guardian: Fit and healthy people who worry about developing an illness may be increasing their risk of heart disease by unnecessarily fretting over their health, research suggests. A study of more than 7,000 people over 12 years found that those with health anxiety at the start of the study were about 70% more likely to develop heart disease than those without that state of mind. Additionally, the researchers found that the higher the reported anxiety, the higher the risk of heart disease. The findings, published in BMJ Open on Thursday, suggest that far from health anxiety protecting people from heart disease through increased monitoring and frequency of checkups, it may have the opposite effect. The study analyzed 7,052 participants in the long-term collaborative research project Norwegian Hordaland health study, all of whom were born between 1953 and 1957. They filled in questionnaires about their health, lifestyle and educational attainment and had a physical checkup between 1997 and 1999. Levels of health anxiety were assessed using a validated scale and the top 10% of the sample -- 710 people -- were considered to have health anxiety. The heart health of all the participants was tracked up to the end of 2009. Anyone who received treatment for, or whose death was linked to, coronary artery disease occurring within a year of entering the study, was excluded on the grounds that they might already have been ill. In all, 234 (3.3%) of the entire sample had an ischemic event -- a heart attack or bout of acute angina -- during the monitoring period. But the proportion of those succumbing to heart disease was twice as high (just over 6%) among those who displayed health anxiety compared with those who did not (3%). After taking account of other potentially influential factors, those with health anxiety at the start of the study were found to be 73% more likely to develop heart disease than those who did not have anxiety at the outset.
