Objective: Organized nationwide screening programme for cervical cancer was introduced in Hungary in 2003. The aim of this study is to analyze the three year screening rate (coverage) of the organized cervical cancer screening programme in women aged less than 25 years. Although women under 25 years are out of the scope of the organized screening programme, but opportunistic screening may be applied. Methods: The data derive from the financial database of the National Health Insurance Fund Administration (OEP) of Hungary covering the period of 2000-2002 (without organized screening) and 2003-2005 (with organized screening). We calculated the three-year screening rate for 2003-2005 according to the age-group of women less than 25 years (15-19 and 20-24). Screening is defined with cytological examination of Papanicolau smear and includes all smears taken either within or outside of the organized programme. Results: The three-year screening rate of women aged 25-64 years was 52.65 % in 2003-2005. The coverage of women under 25 years was the following in 2003-2005: 15-19 years: 31.94 %; 20-24 years: 61.20 %. Comparing this values to the coverage of 2000-2002 (without organized screening) we found a decreasing tendency in these two age-groups: 15-19 years: - 0.06 percent point decrease (non-significant), 20-24 years: -6.28 percent point decrease (p <0.01). Conclusion: We found that coverage of women aged 20-24 being out of the scope of the organized cervical cancer screening programme is higher (61.2 %) than the average of target age group of 25-64 years (52.65). Despite of this finding, the coverage of women 15-19 and 20-24 showed a decreasing tendency following the introduction of organized screening programme.
