(HealthDay)—The percentage of women who visit an obstetrician-gynecologist has declined since 2000, according to a study published online Sept. 5 in Obstetrics & Gynecology.

Alan E. Simon, M.D., and Sayeedha F.G. Uddin, M.D., M.P.H., from the U.S. Department of Health and Human Services in Washington, D.C., used data from the 2000-2015 National Health Interview Surveys to identify the percentage of U.S. women who had visited an ob-gyn and the percentage who had visited a general during the preceding 12 months.

The researchers found that the adjusted percentage of U.S. women who saw a general physician during the preceding 12 months did not significantly change from 2000 to 2015, ranging from 70.1 percent in 2007 to 74.2 percent in 2003 (P > 0.05 for trend). The adjusted percentage who saw an ob-gyn in the preceding 12 months did not change from 2000 to 2003 or 2007 to 2011 (P > 0.05), but it declined from 45 percent to 41.2 percent between 2003 and 2007 and from 41.8 percent to 38.4 percent between 2011 and 2015 (P < 0.001 for trends). The adjusted percentage of women who saw both an ob-gyn and a general physician was 32.4 percent in 2000, growing to 35.2 percent in 2003 but then declining to 29.8 percent in 2015 (P < 0.001 for ).

"To assure high-quality and coordinated care, physicians should identify whether see both health care provider types or only one to help assure that all recommended services are being offered," conclude the authors.
