Trends in prevalence and factors associated with unintended pregnancies in Zambia (2001-2018)

BACKGROUND

Unintended pregnancies can pose significant public health concerns for both maternal and child health because of their associated risks and implications. Experience of unintended pregnancies may lead to delay in seeking antenatal care, thus leading to increased risk of complications during pregnancy and childbirth. Globally, the prevalence of unintended pregnancies has declined. However, the problem remains acute in sub-Saharan Africa. This study was conducted to examine the factors associated with an experience of unintended pregnancy among women of reproductive ages in Zambia.

METHODS

This study used secondary data from the Zambia Demographic and Health Surveys (ZDHSs) which were conducted between 2001 and 2018. A pooled weighted sample of 4,090 pregnant women of reproductive age 15-49 years at the time of the survey was included in the analysis. Multivariable binary logistic regression model was employed to examine the association between independent correlates and experience of unintended pregnancy. All statistical analyses were conducted using Stata software.

RESULTS

Findings show that the proportion of women of reproductive age who experienced unintended pregnancy in Zambia declined from 50.4% (95% CI: 47.1, 53.8) in 2001 to 45.2% (95% CI: 40.5, 49.9) in 2018. The decline in the prevalence of unintended pregnancy is more pronounced among women age groups 25-29 years and 30-34 years. Increasing age was associated with an increased risk of experiencing unintended pregnancies. On the other hand, women who were living in rural areas (aOR = 0.76; 95% CI: 0.58, 1.00) and those with tertiary education (aOR = 0.46; 95% CI: 0.26, 0.80) were less likely to experience an unintended pregnancy. Women who desired a large family (aOR = 0.45; 95% CI: 0.24, 0.85) and those who watched television (aOR = 0.75; 95% CI: 0.59, 0.94) had lower odds of experiencing unintended pregnancies.

CONCLUSIONS

The study has established that the prevalence of unintended pregnancy is still high in Zambia. Women's age, place of residence, level of education, desired family size and exposure to media were associated with the risk of experiencing an unintended pregnancy. Enhancing access to family planning services and commodities targeting women with low education levels will be key to further reduce unintended pregnancies.

Perceived ideal number of children among adolescent girls in sub-Saharan Africa: does exposure to family planning messages matter?

BACKGROUND

Even though evidence shows that fertility transition has begun almost everywhere in sub-Saharan Africa (SSA), the decline has been slower than in other parts of the world. Research shows that there is a positive relationship between fertility levels and fertility preference. Therefore, many countries in the region are implementing family planning education campaigns targeting at influencing reproductive behavior of women. Thus, this study aimed to examine the extent to which exposure to family planning communication influences fertility preferences of adolescent girls in SSA.

METHODS

This study used data extracted from the most recent Demographic and Health Survey datasets for 28 countries in SSA. Analyses were conducted on a pooled sample of 87,950 female adolescents' aged 15-19 years who were captured in respective country's survey. Multivariable binary logistic regression model was fitted in Stata version 17 software to examine the association between exposure to family planning communication and fertility preference among adolescent girls in SSA.

RESULTS

The average fertility preference among adolescent girls in SSA was 4.6 children (95% CI: 4.5, 4.7). Findings show that regardless of the country, adolescents who had exposure to family planning messages [aOR = 0.76, 95% CI = 0.72-0.80] were less likely to prefer 4 or more children. On average, fertility preference among adolescents who had exposure to family planning communication was (3.8 children compared to 4.5 children; p < 0.001) among those with no exposure. Furthermore, results show that married adolescents in SSA who had exposure to family planning message had a higher average preferred family size compared to those who were not married (4.8 versus 3.8; p < 0.001).

CONCLUSION

Exposure to family planning communication has shown the potential to influence adolescents' fertility preference in sub-Saharan Africa. Adolescents with exposure to family planning messages preferred a small family size. Therefore, there is a need to scale-up family planning education programmes in order to reduce fertility further in SSA.

Prevalence and factors associated with early childbearing in sub-saharan Africa: evidence from demographic and health surveys of 31 countries

BACKGROUND

Early childbearing remains a public health concern in sub-Saharan Africa (SSA) because it has substantial implications for women's and children's health and population control. However, little is known about recent changes in early childbearing in the region following the implementation of the Family Planning 2020 initiative (FP2020) national-level interventions. Thus, this study examined factors associated with early childbearing among women in SSA.

METHODS

The study used data from the most recent Demographic and Health Surveys conducted in 31 countries in sub-Saharan Africa between 2010 and 2021. The analysis included a pooled sample of 54,671 parous young women aged 20-24 years. A multivariable binary logistic regression model was used to examine the association between early childbearing and individual and household-level factors. All analyses were weighted to account for complex survey design.

RESULTS

The study shows that the mean prevalence of early childbearing was high in SSA at 39% (95% CI: 35, 43). Chad had the highest prevalence of early childbearing, 62% (95% CI: 60, 64) while Rwanda had the lowest prevalence of 13% (95% CI: 11, 15). Completing secondary school (aOR = 0.57; 95% CI: 0.52, 0.62) or attaining tertiary level education (aOR = 0.32; 95% CI: 0.22, 0.45), first sexual debut in the age range 15-24 years (aOR = 0.15; 95% CI: 0.14, 0.16) and desire for a small family size (aOR = 0.63; 95% CI: 0.58, 0.69) were associated with reduced odds of early childbearing among young women in SSA.

CONCLUSION

The study has established that the prevalence of early childbearing is high in SSA. Level of education, age at first sexual debut, household size, and desired family size are associated with early childbearing in SSA. Governments of SSA countries should enhance sexual and reproductive health interventions to change reproductive behaviour, particularly in adolescents and young women.

A multilevel analysis of trends and predictors associated with teenage pregnancy in Zambia (2001-2018)

BACKGROUND

Teenage pregnancy remains a major social and public health challenge in developing countries especially sub-Saharan Africa (SSA) where prevalence rates are still increasing. Even if considerable effort has been made over the years to study determining factors of teenage pregnancy in SSA, few studies have looked at the trends and associated factors over a longer period. Furthermore, no known study has focussed on both individual and contextual factors influencing teenage pregnancy in Zambia. This study, thus sought to fill this gap in knowledge by simultaneously investigating trends of teenage pregnancy as well as its individual and contextual determining factors.

METHODS

A total pooled weighted sample of 10,010 teenagers (in the age group 15-19) from four waves of the Zambia Demographic and Health Surveys were extracted. Using bivariate analysis, we investigated the trends of teenage pregnancy between 2001 and 2018. Separate multilevel logistic regression models were fitted on pooled teenage pregnancy data in relation to several individual and contextual level factors. Both fixed and random effects were produced. Bayesian parameter estimates were produced using lme4 package in R statistical programming environment.

RESULTS

Results of the trends of teenage pregnancy in Zambia have shown an overall decrease of 2% between 2001 and 2018. Almost all the socioeconomic and demographic variables were consistently associated with teenage pregnancy (p < 0.001) in a bivariate analysis across the four survey. In multilevel analysis, the odds of being pregnant were higher for teenagers who were employed (aOR = 1.21, 95% CI: 1.02-1.42), married (aOR = 7.71, 95% CI: 6.31-9.52) and those with knowledge of ovulation period (aOR = 1.58, 95% CI: 1.34-1.90). On the other hand, belonging to households in high wealth quintiles, being literate, exposure to mass-media family planning messages and delayed sexual debut were associated with decreased odds of teenage pregnancy.

CONCLUSION

The study shows that teenage pregnancy remains a social and public health challenge in Zambia as the country has seen little decrease in the prevalence over the years under consideration. Factors associated with teenage pregnancy include marital status, and employment, knowledge of ovulation period, wealth quintile, sexual debut and exposure to mass-media family planning messaging. Concerted effort must be made to improve literacy levels, reduce poverty and enhance sexual health promotion through the mass media in view of cultural norms, which may prevent parents and children from discussion sexual education topics thus exacerbate the vice.

Association between sexual violence and unintended pregnancy among married women in Zambia

Background

One of the outcomes of sexual violence is unintended pregnancy. In Zambia, 15% of married women age 15—49 years had experienced sexual violence from their husband or partner. The prevalence of unintended pregnancies among women age 15—49 years has risen from 33% in 1992 to 38% in 2018. The link between sexual violence and unintended pregnancy in Zambia was investigated in this study.

Methods

This study used the women's dataset from the 2018 Zambia Demographic and Health Survey, a cross-sectional survey. The study looked at a weighted sample size of 4,465 women age 15 – 49 years. Unintended pregnancy was measured by combining response categories of mistimed and unwanted pregnancy. Multivariate binary logistic regression was performed to establish the net effects of sexual violence and each explanatory variable on unintended pregnancy.

Results

The findings suggest that sexual violence does have a role in unintended pregnancies (AOR 1.74; CI 1.38—2.19). Ever use of contraception is also a significant predictor of unintended pregnancy (AOR 1.48; CI 1.16—1.88), even when other characteristics are taken into account. Results have shown that a woman who had ever used contraception and had experienced sexual violence was more likely to have an unintended pregnancy.

Conclusion

Spousal sexual violence is highly associated with unintended pregnancies in Zambia. Addressing intimate partner sexual violence is among the ways to prevent unintended pregnancies. It is also important to sensitize women on reporting acts of sexual violence to relevant authorities as this will not only prevent reoccurrence of sexual violence but also reduce unintended pregnancies and associated long-term effects.
