Trends in use of acupuncture among adults in Taiwan from 2002 to 2011: A nationwide population-based study.

Abstract

In recent years, acupuncture has gained in popularity worldwide. However, recent epidemiological studies are lacking. We conducted this study to investigate the trends in acupuncture utilization among adults in Taiwan from 2002 to 2011. We analyzed data from the Longitudinal Health Insurance Database 2000 (LHID 2000), which contains all original claims data for 1 million beneficiaries randomly sampled from the registry of all beneficiaries enrolled in the National Health Insurance (NHI) program in 2000. The one-year prevalence of acupuncture use among adults increased from 7.98% in 2002 to 10.9% in 2011. Acupuncture use significantly increased yearly (incidence rate ratio = 1.04, 95% CI = 1.03-1.05, p<0.001). Patients who were female, were middle-aged, resided in highly urbanized areas and suffered from injury or disorders of the musculoskeletal system were prone to more frequent acupuncture use. Our study revealed that the utilization of acupuncture became increasingly popular in Taiwan from 2002 to 2011. Our findings may provide useful information for clinical practice and research as well as for health policy decision making.
