We sought to promote cervical cancer screening among Vietnamese American women in Santa Clara County, Calif.


In 2001-2004, we recruited and randomized 1005 Vietnamese American women into 2 groups: lay health worker outreach plus media-based education (combined intervention) or media-based education only. Lay health workers met with the combined intervention group twice over 3 to 4 months to promote Papanicolaou (Pap) testing. We used questionnaires to measure changes in awareness, knowledge, and Pap testing.


Testing increased among women in both the combined intervention (65.8% to 81.8%; P<.001) and media-only (70.1% to 75.5%; P<.001) groups, but significantly more in the combined intervention group (P=.001). Among women never previously screened, significantly more women in the combined intervention group (46.0%) than in the media-only group (27.1%) obtained tests (P<.001). Significantly more women in the combined intervention group obtained their first Pap test or obtained one after an interval of more than 1 year (became up-to-date; 45.7% to 67.3%, respectively; P<.001) than did those in the media-only group (50.9% to 55.7%, respectively; P=.035).


Combined intervention motivated more Vietnamese American women to obtain their first Pap tests and to become up-to-date than did media education alone.
