Epidemiology: Social Anxiety Disorder - Highly co-morbid anxiety disorder will continue to remain a significant public health burden

Abstract

Synopsis

Overview of social anxiety disorder definition and a review of the epidemiology literature. This report provides in-depth analysis of patient populations, a 10-year prevalent case forecast, and key patient segments across the seven major markets.

Description

INTRODUCTION

In 2011, Datamonitor estimates that there were approximately 19.098 million men and women with SAD in the seven major markets (the US, Japan, France, Germany, Italy, Spain, and the UK), and more than three quarters of these cases (79%) were found in the US alone.

FEATURES AND BENEFITS

  • Gain insight into market potential, including a robust 10-year epidemiology forecast of social anxiety disorder prevalent cases.
  • Understand the key epidemiologic risk factors and co-morbidities associated with SAD.

HIGHLIGHTS

  • Datamonitor estimates that the prevalence of SAD in the seven major markets is highest among US adults aged 20-29 years and also 30-39 years; both age groups are projected to have a significant increase in the number of prevalent cases during the forecast period, according to Datamonitor forecasts.
  • Prevalent cases of SAD in adults aged 20-29 and 30-39 years in the five major EU markets (France, Germany, Italy, Spain, and the UK) and Japan will remain relatively stable throughout the forecast period.

YOUR KEY QUESTIONS ANSWERED

  • What are the most robust sources for social anxiety disorder prevalence data?
  • How will the patient population change over the next decade in the seven major markets?
  • What are the major co-morbid conditions with SAD that contribute to the severity of the disorder?
  • How will the proposed changes to the current SAD diagnostic criteria affect the total prevalence of SAD near the end of the forecast period?

DRIVERS OF SOCIAL ANXIETY DISORDER EPIDEMIOLOGY

  • Although SAD onset is typically in early adolescence, clinical diagnosis may be up to a decade after disease onset
  • Like other anxiety disorders, SAD is typically more prevalent in women than men
  • SAD is highly co-morbid with other psychiatric disorders
  • Up to 20% of people with an eating disorder also have SAD
  • Drug and alcohol dependence are common among those with SAD
  • Familial environmental factors affect SAD development
  • Family history may increase risk of SAD threefold

EPIDEMIOLOGIC RESULTS

  • Current prevalent cases and future trends
  • Average annual growth rate of social anxiety disorder total prevalence
  • Age-standardized results for prevalent cases of social anxiety disorder
  • Subpopulations for prevalent cases of social anxiety disorder
    • In 2011, over 46% of all prevalent cases of social anxiety disorder occurred in adults under the age of 40 in the seven major markets

DISCUSSION

  • Limitations of Datamonitor's epidemiologic projections
