Background: Sexual intercourse among teenagers has increasingly become a social, economic and health problem. It results in unintended pregnancy, unsafe abortion and sexual transmitted diseases, especially HIV infection. The sexual behaviors among teenagers in Ubon Ratchathani Province may be different from the other provinces and other parts of Thailand.
Objective: To study the rate of and factors associated with sexual intercourse among female teenagers in Ubon Ratchathani Province.
Methods: This cross-sectional survey study aimed to determine factors associated with sexual intercourse among 106 female teenagers aged 15-19 years old in Ubon Ratchathani Province. Data was collected using self-administrated questionnaires.
Results: The results showed that 40.6% of female teenagers have had coitus. The mean age of the first coitus was 17.4 years old. All of their partners were their lovers. Love is the main reason for having first coitus (58.1%) but 9.3% reported that they were forced. Significant factors associated with coitus were age, residence, sexual behavior of close friends, parental marital status and internet communication with strangers. By logistic regression analysis, age and sexual behavior of close friends were the only two factors significantly associated with coitus among teenagers.
Conclusion: The rate of sexual intercourse among female teenagers in Ubon Ratchathani Province was fairly high. Most of the factors associated with sexual intercourse were socioeconomic aspects.
