The results showed that the prevalence of abnormal Pap smears was12.2% in Akha women and 4.5% in urban women. The highest prevalence of Pap abnormalities was found inthe 41-50 years age group in both populations (4.5% in Akha and 1.7% in urban women). In both populations,abnormal Pap smears were found in <21 years age groups. From the questionnaires, the possible risk factors  related to the higher prevalence of abnormal pap amears in Akha woman wrew early age at marriage(17 years), high frequency pregnacies and high parity and no/low education level. In conclusion, cervical cancer control by education and early detection by Pap smear screening is necessary for hill tribe women. More Pap smear screening service units should be set to improve the coverage for the risk group women who got married in young age, especial in ethnic groups.
