Pattern of cervical screening utilization in Italy.

The pattern of cervical screening utilization in Italy was analyzed using data from the 1986-1987 National Health Survey on the basis of a sample of 27,455 women aged 20 to 79 randomly selected within strata of municipality of residence and age in order to be representative of the whole Italian population. Overall, about 17% of women aged 20 to 79 were screened per year, for a total of 3.5 to 4 million cervical smears per year. The highest frequency was reported in younger middle age, about one in four women being screened per year in the age groups 30 to 49, and there was a substantial decline above age 50. Cervical smear rates were higher in Northern areas (22%), where mortality from cervical cancer is lower, than in the Centre (16%) and South (11%) of the country. Further, there was a strong positive social class gradient in the utilization of cervical screening, in relation to both education and occupation. In spite of the absence of any organised mass screening program, cervical screening is a relatively common procedure among Italian women. However, this study provides further quantitative evidence of a markedly irrational utilization of non-organized cervical screening, which tends to end up selectively used by the groups in which cervical cancer is less common.
