Introduction:
This is a study regarding the perception towards the use of the contraceptive pill in two different adolescent populations of Thrace.

Material and Methods:
Adolescent women aged (mean 15.9, min 13 max 19 years, SD 2.51), belonging to the two main religious subgroups of Thrace (168 Orthodox Christians and 118 Muslims), during their visits to the family planning clinic of Democritus University of Thrace were invited to answer an anonymous questionnaire designed to investigate the contraceptive behavior of women in Thrace. The subject of the questions was the investigation of the women's level of information, the frequency of using the contraceptive pill, the sense of security it offers them in relation to contraception and the incidence of side effects depending on the time of taking it. The severity of the reported side effects and their role as a reason for discontinuation of contraceptive treatment were assessed.

Results:
A significant percentage of the Christian women surveyed expressed a positive view of the usefulness of the oral contraceptive pill as a method of contraception. Muslim women appeared less willing to use it as a relatively high percentage do not consider it a safe contraceptive method and consider taking it daily as a deterrent 5.1% of women experienced mild side effects with contraceptive use but only 4.7% discontinued treatment because of them. The marital status, the level of education and the frequency of contacts of the respondents were factors that strongly influence their sexual behavior.

Conclusions:
The contraceptive practice of Thracian women shows significant differences between the two subgroups under study and is directly influenced by the different socioeconomic characteristics of each.
