The association held true even after adjustment for age, health status, number of chronic illnesses, number of medications, and exercise, as well as measured weight loss and change in plasma cholesterol in the previous 13 years. The median survival after dementia was six months. Using a proportional hazards model, risk factors for more rapid development of dementia included anaemia and low body mass index and older age at AIDS onset. In a multivariate model, pre-AIDS hemoglobin remained the most significant predictor of dementia. Prevalence of depressive symptoms in primary care.
Depression is one of the most common disorders seen in primary care.
This study attempted to estimate the prevalence of depressive symptoms in primary care across the United States. Survey data were obtained from a sample of 75,858 patients who visited one of 765 participating primary care physicians for any reason from February 1991 to September 1991. The outcome measurement used was the Zung Self-rating Depression Scale. Women, those in older age groups, and those with lower educational attainment were more likely to have clinically significant depressive symptoms. Married men and women were the least likely to have clinically significant depressive symptoms.
