This Case - control study research aimed to determine the influencing of knowledge of contraceptive implants, attitude toward contraceptive implants, family planning, and the influence of significant person to primiparous adolescent mothers. The research participants were 134 primiparous adolescent mothers who were admitted at postpartum ward or who visited family planning department at Banglamung hospital and Queen Savang Vadhana Memorial hospital. They were recruited in the study by using convenience sampling technique. The research instruments were personal information and postpartum contraceptive implants record forms, knowledge on contraceptive implants questionnaire, attitude toward contraceptive implants questionnaire, and the influence of significant persons toward contraceptive implants use questionnaires. Reliability of questionnaires were .73, .83, .91 respectively. Data were analyzed using descriptive statistics and logistic regression analysis.
The results revealed that the factor influencing the use of postpartum contraceptive implants was the influence of significant persons (AOR = 1.11, 95% CI = 1.05-1.17) indicating that participants with high influences of significant persons were 1.11 times more likely to use contraceptive implants than those with low influence of significant persons. Finding of this study suggested that nurses and midwives at postpartum units and family planning clinic should include significant persons of adolescent mothers to participate in postpartum contraceptive counselling. It might encourage to increase the use of postpartum contraceptive implants and prevent repeated rapid pregnancies among adolescent mothers.
