Differences in the Use of Family Planning Methods by Adolescent Females According to the Education Model Utilized During Pregnancy. Monterrey, Mexico

Abstract

Background: The objective was to compare the use of family planning methods during the immediate postpartum period and two years following childbirth among the adolescent females who had followed two different intervention programs during their pregnancies. Methods: A quasi-experimental study was designed. A total of 62 pregnant adolescents were selected to comprised two intervention groups, the PRECEDE model and the Health Belief model (MCS) groups. Non-parametric statistical tests were employed and 95% confidence intervals estimated. Results: The average starting knowledge in the MCS groups was 69.12 points (95% CI 63.27-74.97) and ending 89.71 points (95% CI 86.24- 93.17), while the starting knowledge for the PRECEDE group was 49.39 points (95% CI 42.24- 56.54) and ending 75.25 points (95% CI 71.12- 79.38). IN the immediate postpartum, 93% (95% CI 83.5-100) of the adolescents in the PRECED group accepted the use of a family planning method similar to that employed by the MCS group, of 94.2 (95% CI 86.3-100). As regards the continued use of the method, that is, two years later, the PRECEDE strategy had a greater effect that the MCS strategy, respectively 92% (95% CI 82-100) and 72% (95% CI 56.9-87.1). Conclusions: A difference was found to exist between models as regards the use of family planning methods 2 years following childbirth. The PRECEDE program is proposed as the education strategy for preventing a second pregnancy among adolescent females
