Summary: Researchers report depression and anxiety may be as detrimental to your health as smoking or obesity. The study found those with anxiety of depression are at a 65% increased risk of stroke, 87% increased risk of arthritis and 64% increased risk of stroke, compared to those without the disorders.
An annual physical typically involves a weight check and questions about unhealthy habits like smoking, but a new study from UC San Francisco suggests health care providers may be overlooking a critical question: Are you depressed or anxious?
Anxiety and depression may be leading predictors of conditions ranging from heart disease and high blood pressure to arthritis, headaches, back pain and stomach upset, having similar effects as long-established risk factors like smoking and obesity, according to the new research.
In the study, first author Andrea Niles, PhD, and senior author Aoife O’Donovan, PhD, of the UCSF Department of Psychiatry and the San Francisco VA Medical Center, looked at the health data of more than 15,000 older adults over a four-year period.
They found that 16 percent (2,225) suffered from high levels of anxiety and depression, 31 percent (4,737) were obese and 14 percent (2,125) were current smokers, according to their study published in the journal Health Psychology on Dec. 17, 2018.
Participants with high levels of anxiety and depression were found to face 65 percent increased odds for a heart condition, 64 percent for stroke, 50 percent for high blood pressure and 87 for arthritis, compared to those without anxiety and depression.
“These increased odds are similar to those of participants who are smokers or are obese,” said O’Donovan, who, with Niles, also is affiliated with UCSF Weill Institute for Neurosciences. “However, for arthritis, high anxiety and depression seem to confer higher risks than smoking and obesity.”
Cancer an Exception to Conditions Impacted by Depression and Anxiety
Unlike the other conditions investigated, the authors found that high levels of depression and anxiety were not associated with cancer incidence. This confirms results from previous studies, but contradicts a prevailing idea shared by many patients.
“Our findings are in line with a lot of other studies showing that psychological distress is not a strong predictor of many types of cancer,” O’Donovan said. “On top of highlighting that mental health matters for a whole host of medical illnesses, it is important that we promote these null findings. We need to stop attributing cancer diagnoses to histories of stress, depression and anxiety.”
Niles and O’Donovan discovered that symptoms such as headache, stomach upset, back pain and shortness of breath increased exponentially in association with high stress and depression. Odds for headache, for example, were 161 percent higher in this group, compared with no increase among the participants who were obese and smokers.
Treating Mental Health Can Cut Health Care Costs
“Anxiety and depression symptoms are strongly linked to poor physical health, yet these conditions continue to receive limited attention in primary care settings, compared to smoking and obesity,” Niles said. “To our knowledge this is the first study that directly compared anxiety and depression to obesity and smoking as prospective risk factors for disease onset in long-term studies.”
The results of the study underscore the “long-term costs of untreated depression and anxiety,” said O’Donovan. “They serve as a reminder that treating mental health conditions can save money for health systems.”
The two authors evaluated health data from a government study of 15,418 retirees, whose average age was 68. Depression and anxiety symptoms were assessed using data from participant interviews. Participants were questioned about their current smoking status, while weight was self-reported or measured during in-person visits. Medical diagnoses and somatic symptoms were reported by participants.

Comparing anxiety and depression to obesity and smoking as predictors of major medical illnesses and somatic symptoms
Objective: Anxiety and depression predict poor physical health longitudinally, but are neglected in primary care settings compared to other risk factors such as obesity and smoking. Further, anxiety has been less commonly studied than depression, and whether anxiety has unique predictive effects for physical health is unknown. We compared anxiety and depression to obesity and smoking as predictors of physical health indices and examined unique predictive effects of anxiety and depression.
Method: Using data from the Health and Retirement study, a US population-based cohort study of older adults, we tested longitudinal associations of anxiety and depression symptoms with onset of self-reported physical health indices (N = 15,418; M age = 68). Medical illnesses (heart disease, stroke, arthritis, high blood pressure, diabetes, and cancer) and somatic symptoms (stomach problems, shortness of breath, dizziness, back pain, headache, pain, and eyesight difficulties) were assessed on two occasions over four years. Anxiety and depression were measured at the initial time point and tested as predictors of medical illness and somatic symptom onset.
Results: Anxiety and depression symptoms predicted greater incidence of nearly all medical illnesses and somatic symptoms. Effects were as strong as or stronger than those of obesity and smoking, and anxiety and depression independently increased risk for most physical health indices assessed.
Conclusions: Findings suggest that anxiety and depression are as strongly predictive of poor future physical health as obesity and smoking and that anxiety is independently linked to poor physical health. Greater attention should be paid towards these conditions in primary care.
