Introduction: Adolescent pregnancies are high risk pregnancies and pose severe obstetric risks to the mother and her baby. Repeat adolescent pregnancies present an extension of the obstetric risks, both in the short and long term. Despite the associated public health concerns about repeat adolescent pregnancy, they remain a common occurrence and so does the associated comorbidities. Family planning provision is aimed at reducing the occurrence of repeat pregnancies especially in this age group. The study sought to determine the uptake and associated factors of postpartum family planning among adolescent mothers at Kasangati Health Center IV. Methods: We conducted a cross-sectional study among adolescent mothers who were within their first two years of the postpartum period between February and March, 2020. Enrolment sites included the postnatal clinic, young child and immunisation clinic, exposed infant clinic and the outpatient department. We used an interviewer administered questionnaire to capture data on participant social and clinical characteristics. All data were entered into Epi Data and exported to STATA for analysis. Uptake was expressed as a percentage. Bivariate analysis was done using Chi squares to identify factors associated with uptake of postpartum family planning. Multivariate logistic regression was done to establish the factors independently associated with uptake of postpartum family planning. Findings: A total of 230 mothers were enrolled. Postpartum family planning uptake was found to be 52.6% (95%CI=50.0-55.2) and the CPR was 57% (95%CI=54.5-62.1). Significant associated factors included: Cohabiting or married at delivery (AOR=0.05, 95% CI=0.01-0.27), lack of antenatal and postnatal family planning counselling (AOR=0.15, 95% CI=0.05-0.48) and (AOR=0.03, 95% CI=0.01-0.06), respectively, and also no history of family planning use in sexual debut (AOR=0.32, 95% CI=0.19-0.53). These reduced the odds of postpartum family planning uptake. Conclusion and Recommendation: Although the uptake of postpartum family planning was moderately high, majority of users were inconsistent or only utilized for less than 12 months continuously. Thus, the protection was not optimum in the two years postpartum to prevent repeat adolescent pregnancy. Antenatal and postnatal family planning counselling could improve on the uptake, consistency and continuous utilization of postpartum family planning especially among those adolescents in well-established unions.
