Background: In Thailand, there has been a high incidence of adolescent pregnancy which leads to major public health and socioeconomic problems such as unplanned pregnancy, induced abortion and negative impacts on the health of the mothers and newborns. Contraception among adolescents is so important that it can prevent those problem, especially subdermal etonogestrel implant which are recommended to be effective and suitable for adolescents.
Objective: To study the rate of use and factors associated with the use of subdermal etonogestrel implants among postpartum primipara adolescents in Saraburi province.
Methods: This study is an observational descriptive research. The population were 106 primipara adolescents at 4 - 6 weeks postpartum period at three hospitals in Saraburi province (ie, Saraburi Hospital, Pra-putabat Hospital, and Banmoh Hospital). Data was collected by interviewing postpartum primipara adolescents from March 21, 2016, to June 30, 2016. Data was analyzed by descriptive statistics which included frequency, percentage, mean and stranded deviation. Test of hypothesis was done by chi-square test, Fisher’s exact test and multiple logistic regression analysis with the significant level at P < 0.05.
Results: Among 106 postpartum primipara adolescents, 93.4% used contraceptives (31.1% used subdermal etonogestrel implant; 62.3% used other reversible contraceptions [eg, depot medroxyprogesterone acetate injection, oral contraceptions and condoms]), and 6.6% used no contraception. By univariate analysis, factors significantly associated with the use of implant among primipara adolescents included age of primipara adolescents, age of husband, expense, convenience of use, side effects, application pain, duration of contraception and medical personnel’s recommendation. When multiple logistic regression analysis was applied, only four factors were significantly associated with the use of implant. The most significant factor was medical personnel’s recommendation. The other significant factors were expense, age of husband and duration of contraception.
Conclusion: Most of primipara adolescents at 4 - 6 weeks postpartum period in Saraburi province used contraceptives. Subdermal etonogestrel implants was the second most common contraceptive used. The most important factor for the use of implant was medical personnel’s advice which emphasized on the use of implants in order to prevent unplanned pregnancy among adolescents.
