SPSS Spread sheet data and De-identified Focused Group Discussion Key Informant Interview data

Background: Unintended pregnancy is defined as a desired or unwanted pregnancy that occurs in a woman who is not planning to have any (more) children. Unintended pregnancy poses a wide array of health risks for both the mother and child, including malnutrition, illness, abuse, neglect, and even death. Local data on the prevalence of unintended pregnancy in Osun State are lacking, creating a significant knowledge gap. Therefore, this study examined the prevalence of unintended pregnancy and its associated factors among women of reproductive age in Osun State. Method: This study employed a mixed-method design of quantitative and qualitative methods among women of reproductive age selected from six local government areas in Osun State. The sample size for the quantitative component was estimated to be 198, calculated using Le Fischer’s formula (n= z2pq/d2), and 32 participants were purposively selected for the qualitative study. A multistage sampling technique was used to select the respondents for the qualitative study. Quantitative data were collected using a semi-structured, interviewer-administered questionnaire. Qualitative data involved key informant interviews and focus group discussions (FGD). Quantitative data were entered and analyzed using SPSS version 24, with the significance level set at p ≤ 0.05. Qualitative analysis was coded and analyzed using Atlas ti version 24. Results: The prevalence of unintended pregnancies was 42.4%. At the multivariate level, using regression analysis, age (B=0.151, p<0.001, C.I =0.075-0.266), marital status (B= 2.626, p=0.030, C.I=-0.499 to -0.262), residence (B=2.109, p<0.001, C.I=1.153-3.066), and religious affiliation (B= 1.848, p<0.001, C.I= -2.777 to -0.918) were significantly associated with unplanned pregnancy. Conclusion: There was a high prevalence of unintended pregnancies among respondents linked to social, cultural, and religious factors. Hence, public health initiatives should address these factors to reduce unintended pregnancies and improve the uptake of family planning services among women in Osun State.
