Note: Based on 10,134 elderly Medicare beneficiaries aged 65 or older and who were followed for 3-years and were first interviewed either in 1999 or 2000 or 2001 or 2002 or 2003 and lived in the community. Asterisks represent significant group differences between the reference group and other groups.
Model 1a is an unadjusted model with only antidepressant use as the independent variable.
Model 1b included antidepressant use and diagnosed depression as the independent variables.
Model 1c included additionally controlled for gender, race/ethnicity education, poverty status, prescription drug insurance, health status, functional status, body mass index, smoking, presence of heart disease and hypertension.
Model 2 is ?
All logistic regression models included intercepts.
Long-term use represents antidepressant prescriptions reported for all 3-years; short-term use represents antidepressant prescriptions reported in one or two years. Depression represents presence of depression in one or more years.
