Background Unmet need for family planning among married women is still a public health concern in sub-Saharan Africa. In Zambia, one in every five married women had an unmet need for family planning in 2018. Unmet need for family planning has the potential to increase the number of unintended pregnancies and unsafe abortions. These factors can increase the proportion of women of child bearing age, who are at high risk of birth complications. This study was therefore conducted to understand the determinants of unmet need for family planning among married women in Zambia based on recent cross-sectional data. Methods The study analysed data extracted from the Zambia Demographic and Health Survey, which was a representative cross-sectional survey conducted in 2018. The analysis was done on a sample of 7598 currently married women aged 15–49 years. Multivariate logistic regression was used to examine determinants of unmet need for family planning in Zambia. The analyses was weighted to account for complex sample design. Results Prevalence of unmet need for family planning is still high in Zambia at 20%. Women in the age groups 25–34 and 35–49 were less likely to have total unmet need for family planning (AOR = 0.61; 95% CI 0.47, 0.78) and (AOR = 0.63; 95% CI 0.45, 0.86) respectively, compared with those aged 15–24 years. Age of a woman, parity, household wealth and exposure to media-based family planning messages were found to be significantly associated with unmet need for family planning among married women. Conclusion There were significant differences in unmet need for family planning based on a woman's age, number of children ever born, wealth level, and exposure to media-based family planning messaging. Improving access to family planning messages and addressing underlying structural factors that improve the wealth status, particularly among young women, may help to reduce unmet need for family planning in Zambia.

Introduction: Unmet need for family planning among married women is still high in Africa. In the year 2018, one in every five married women in Zambia had an unmet need for family planning. Unmet need for family planning can increase the number of unintended pregnancies and abortions, both of which have the potential to increase the proportion of women of child bearing age who are at high risk of birth complications. Studies have shown that factors explaining unmet need for family planning vary significantly from country to country, depending on access and availability of family planning services for women. We conducted this study to understand the determinants of unmet need for family planning in Zambia. Knowledge of factors associated with unmet need for family planning can help governments and stakeholders to identify health strategies to reduce unwanted fertility and prevent maternal and child mortality.Methods: The study used datasets from the Zambia Demographic and Health Survey which was a representative cross-sectional survey conducted in 2018. Zambia conducted a Demographic and Health to capture health indicators which are used to measure progress of implementation of health sector interventions. We did analysis on a sample of 7, 597 married women aged 15-49 years. Chi-square test and multivariate logistic regression were used to analyse determinants of unmet need for family planning. Stata version 14.2 was used to analyse weighted data and survey commands were applied to account for the complex sample design. Results: Study findings have revealed that half of the married women were still not using contraception by 2018. Unmet need for family planning among married women is still a public health issue in Zambia. In multivariate regression analysis; age, parity, household wealth and exposure to media-based family planning messages were found to be significantly associated with unmet need for family planning among married women.Conclusion: There is need to enhance family planning policy and programming in the country in order to achieve desired health outcomes. Mass media campaigns and community-based outreach activities with special focus on the young women can achieve significant results in reducing unmet need for family planning. Further, there should be some deliberate interventions to conduct family planning talks during in health facilities targeting women who visit maternal and children care clinics.

Background: Measles–rubella supplementary immunization activities (MR-SIAs) are conducted to address inequalities in coverage and fill population immunity gaps when routine immunization services fail to reach all children with two doses of a measles-containing vaccine (MCV). We used data from a post-campaign coverage survey in Zambia to measure the proportion of measles zero-dose and under-immunized children who were reached by the 2020 MR-SIA and identified reasons associated with persistent inequalities following the MR-SIA. Methods: Children between 9 and 59 months were enrolled in a nationally representative, cross-sectional, multistage stratified cluster survey in October 2021 to estimate vaccination coverage during the November 2020 MR-SIA. Vaccination status was determined by immunization card or through caregivers’ recall. MR-SIA coverage and the proportion of measles zero-dose and under-immunized children reached by MR-SIA were estimated. Log-binomial models were used to assess risk factors for missing the MR-SIA dose. Results: Overall, 4640 children were enrolled in the nationwide coverage survey. Only 68.6% (95% CI: 66.7%, 70.6%) received MCV during the MR-SIA. The MR-SIA provided MCV1 to 4.2% (95% CI: 0.9%, 4.6%) and MCV2 to 6.3% (95% CI: 5.6%, 7.1%) of enrolled children, but 58.1% (95% CI: 59.8%, 62.8%) of children receiving the MR-SIA dose had received at least two prior MCV doses. Furthermore, 27.8% of measles zero-dose children were vaccinated through the MR-SIA. The MR-SIA reduced the proportion of measles zero-dose children from 15.1% (95% CI: 13.6%, 16.7%) to 10.9% (95% CI: 9.7%, 12.3%). Zero-dose and under-immunized children were more likely to miss MR-SIA doses (prevalence ratio (PR): 2.81; 95% CI: 1.80, 4.41 and 2.22; 95% CI: 1.21 and 4.07) compared to fully vaccinated children. Conclusions: The MR-SIA reached more under-immunized children with MCV2 than measles zero-dose children with MCV1. However, improvement is needed to reach the remaining measles zero-dose children after SIA. One possible solution to address the inequalities in vaccination is to transition from nationwide non-selective SIAs to more targeted and selective strategies.
