Access to mass media and teenage pregnancy among adolescents in Zambia: a national cross-sectional survey

Pooled prevalence and associated factors of teenage pregnancy among women aged 15 to 19 years in sub-Saharan Africa: evidence from 2019 to 2022 demographic and health survey data

BACKGROUND

Teenage pregnancy is becoming one of the most common social and public health problems worldwide, with the highest prevalence in sub-Saharan Africa. Health risks and adverse outcomes of pregnancy and childbirth among adolescent girls are the commonest cause of the global burden of maternal morbidity and mortality. This study is intended to determine the pooled prevalence and determinants of teenage pregnancy in sub-Saharan Africa using the most recent demographic and health survey data (2019-2022).

METHODS

A cross-sectional study was conducted using data from the most recent demographic and health surveys of four countries (Kenya, Tanzania, Gabon, and Cameroon) in sub-Saharan Africa conducted between 2019 and 2022. A total weighted sample of 12,829 teenagers aged 15 to 19 years was included in the study. Data extracted from demographic and health survey data sets were cleaned, recorded, and analyzed using STATA/SE version 14.0 statistical software. Multilevel mixed-effects logistic regression was used to determine the factors associated with the dependent variable. Finally, variables with a p-value ≤ 0.05 and an adjusted odds ratio with a 95% confidence interval were declared statistically significant.

RESULTS

The pooled prevalence of teenage pregnancy among women aged 15 to 19 years was 18.15% (95% CI: 17.49, 18.83). Teenage pregnancy was positively associated with the respondent's age [AOR = 2.97; 95% CI (2.55, 3.46)], educational status [AOR = 2.21; 95% CI (1.62, 3.03)] and [AOR = 1.80; 95% CI (1.54, 2.12)], wealth status [AOR = 2.61; 95% CI (2.12, 3.22)] and [AOR = 1.65; 95% CI (1.33, 2.05)], relation to the household head [AOR = 2.09; 95% CI (1.60, 2.72)], and unmet need for contraception [AOR = 14.3; 95% CI (11.5, 17.8)]. On the other hand, it was negatively associated with marital status [AOR = 0.08; 95% (0.07, 0.10)], working status [AOR = 0.75; 95% CI (0.64, 0.88)], age at first sex [AOR = 0.68; 95% CI (0.58, 0.80)], contraceptive use [AOR = 0.25; 95% CI (0.20, 0.30)], contraceptive knowledge [AOR = 0.27; 95% CI (0.19, 0.40)], and community contraceptive utilization [AOR = 0.85; 95% CI (0.73, 0.99)].

CONCLUSION

In the current study, one out of six young women aged 15 to 19 experienced teenage pregnancy. Therefore, addressing unmet needs for family planning, improving women's educational status, and giving special attention to teenagers with low educational and economic status are recommended.

Impact of sexual and reproductive health interventions among young people in sub-Saharan Africa: a scoping review

Objectives

The aim of this scoping review was to identify and provide an overview of the impact of sexual and reproductive health (SRH) interventions on reproductive health outcomes among young people in sub-Saharan Africa.

Methods

Searches were carried out in five data bases. The databases were searched using variations and combinations of the following keywords: contraception, family planning, birth control, young people and adolescents. The Cochrane risk-of-bias 2 and Risk of Bias in Non-Randomized Studies-of-Interventions tools were used to assess risk of bias for articles included.

Results

Community-based programs, mHealth, SRH education, counselling, community health workers, youth friendly health services, economic support and mass media interventions generally had a positive effect on childbirth spacing, modern contraceptive knowledge, modern contraceptive use/uptake, adolescent sexual abstinence, pregnancy and myths and misperceptions about modern contraception.

Conclusion

Sexual and reproductive health interventions have a positive impact on sexual and reproductive health outcomes. With the increasing popularity of mHealth coupled with the effectiveness of youth friendly health services, future youth SRH interventions could integrate both strategies to improve SRH services access and utilization.

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.

Exposure to family planning messages and teenage pregnancy: results from the 2017 Philippine National Demographic and Health Survey

BACKGROUND

Teenage pregnancy is known to have physical, emotional, and psychosocial effects. Because of these risks, family planning and contraception messages have been disseminated in various forms of media, but their association with teenage pregnancy has not been studied previously in the Philippines. This study aims to examine the association between exposure to various family planning and contraception messages disseminated in various media channels and pregnancy among Filipino women aged 15-19. The study also intended to examine interactions between the different media channels where these family planning and contraception messages are being disseminated on their effect on teenage pregnancy.

METHODS

We used data from the individual recode of the 2017 Philippine National Demographic and Health Survey. We used logistic regression for survey data to  study the association between exposure to family planning and contraception messages and teenage pregnancy.

RESULTS

Out of 5120 respondents, 44% of respondents have accessed information on contraception from the internet, 25% have heard information about contraception through the radio, 55% of respondents have heard about contraception via television, 15% have read about contraception in the newspapers and magazines, and only 6% have received information on contraception via short messaging service (SMS). There were 420 (8.56%) who have ever been pregnant. After adjusting for confounding variables, those who were exposed to family planning/contraceptive messages via the internet (aOR: 0.90; 95% CI: 0.59, 1.35) and newspapers/magazines (aOR: 0.78; 95% CI: 0.44, 1.41) have lower odds of teenage pregnancy, but no strong evidence of their effectiveness. On the other hand, exposure to family planning messages through the radio (aOR: 1.06; 95% CI: 0.71, 1.59), television (aOR: 1.09; 95% CI: 0.72, 1.65), and short messaging service (aOR: 1.29; 95% CI: 0.51, 3.22) marginally increase the risk of teenage pregnancy. We did not find any pairwise interactions between the different exposure variables.

CONCLUSIONS

Our results highlight the need to improve the content and key messages of contraceptive and family planning messages in the Philippines, especially those that are broadcasted online and in print media. There is also a need to increase the reach of these different family planning and contraception messages, especially by utilizing social media and other print and online media platforms commonly used by the youth.

Rural-urban correlates of modern contraceptives utilization among adolescents in Zambia: a national cross-sectional survey

Background

Modern contraceptive use among adolescents is low despite the adverse effects of adolescent pregnancies. Understanding correlates of modern contraceptive use in different settings is key to the design of effective context-specific interventions. We aimed to determine factors associated with modern contraceptives use among adolescents in rural and urban settings of Zambia.

Methods

We analyzed secondary data from 2018 Zambia demographic and health survey (ZDHS) focusing on adolescent girls aged 15–19 years. We used multivariable logistic regression in SPSS version 25 to examine rural-urban variations in factors associated with modern contraceptive utilization.

Results

Overall, 12.0% (360/3000, 95% CI: 10.9–13.2) of adolescents in Zambia were using modern contraceptives. Use of modern contraceptives was higher in rural areas at 13.7% (230/1677, 95% CI: 12.1–15.3) compared to 9.8% (130/1323, 95% CI: 8.3–11.6) in urban areas. In the rural areas, having a child (aOR = 13.99; 95% CI 8.60–22.77), being married (aOR = 2.13; 95% CI 1.42–3.18), being older at 19 years (aOR = 3.90; 95% CI 1.52–10.03), having been visited by a field health worker (aOR = 1.62; 95% CI 1.01–2.64), having been exposed to family planning messages on mass media (aOR = 2.87; 95% CI 1.01–8.18) and belonging to the richest wealth quintile (aOR = 2.27; 95% CI 1.43–3.62) were associated with higher odds of contraceptive utilization. Furthermore, adolescents in the Northern (aOR = 0.29; 95% CI 0.11–0.80) and Luapula (aOR = 0.35; 95% CI 0.15–0.81) provinces were associated with less odds of utilizing contraceptives compared to those in Western province. In the urban areas, older age at 19 years (aOR = 4.80; 95% CI 1.55–14.84) and having a child (aOR = 18.52; 95% CI 9.50–36.14) were the only factors significantly associated with modern contraceptive utilization.

Conclusion

Age and having a child were associated with modern contraceptive use in both rural and urban areas. In rural areas (province, marital status, being visited by field health workers, family planning messages exposure and wealth index) were the only associated factors. This indicates that interventions aiming to increase contraceptive utilization should be context specific.
