| Abstract | BACKGROUND: Initiation of antidepressant treatment for depression may be associated with new onset (emergent) anxiety. OBJECTIVE: The purpose of this study was to assess demographic and clinical factors associated with emergent anxiety following a new antidepressant start among Department of Veterans Affairs (VA) Health System patients with depression. METHODS: Using a retrospective cohort design, we obtained data from 328,888 VA patients with depression who were newly prescribed 1 of the 7 most commonly used antidepressant drugs between April 1999 and September 2004 from the VA National Depression Registry. We examined the prevalence of emergent anxiety, defined as either a new anxiety diagnoses or by new antianxiety medication starts, during the 12 weeks following new antidepressant start. In multivariate analyses, we assessed the hazard ratios for emerging anxiety associated with patient characteristics and specific antidepressant agents. RESULTS: Approximately 3% of patients developed clinically significant anxiety within 12 weeks of starting an antidepressant drug regimen. Younger age (age <45 years and 45-64 years) was associated with higher risks for emergent anxiety than older age (≥65 years) (hazard ratio [HR] = 1.72 and 1.55; 95% CI, 1.59-1.85, and 1.38-1.72, respectively). Female gender was associated with higher risks than male gender (HR = 1.17; 95% CI, 1.10-1.26), and white and other races compared with black race were associated with higher risks of emergent anxiety (HR = 1.49 and 1.13; 95% CI, 1.30-1.59 and 1.04-1.23, respectively). Finally, filling antidepressant drug prescriptions in years subsequent to 1999 was associated with lower risks of emergent anxiety. CONCLUSIONS: Only a small proportion of patients developed emergent anxiety following a new antidepressant start, resulting in a new diagnosis or antianxiety medication use. Anxiety occurred more often in young adults, whites, and women. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
