Trends and factors associated with adolescent pregnancies in Tanzania from 2004-2016: Evidence from Tanzania Demographic and Health Surveys.

Background: Adolescent pregnancy increases the risk of maternal and child morbidity and mortality. We aimed to determine trends and factors associated with adolescent pregnancy in Tanzania from 2004 to 2016 using the Tanzania Demographic and Health surveys (TDHS). Methods: We carried out an analytical cross-sectional study using the TDHS data for the years 2004 to 2005, 2010 and 2015 to 2016 among adolescent girls aged 15 to 19 years. Data analysis was performed using STATA version 15. Data analysis considered the complex survey design inherent in the demographic and health survey (DHS) data. The Poisson regression model was used to estimate Prevalence Ratios (PR) and 95% confidence intervals for factors associated with adolescent pregnancy. Results: We analysed data for a total of 10,972 adolescents for the three TDHS rounds. The proportion of adolescent pregnancy significantly decreased from 26% to 22.8% from the year 2004/05 to 2010 and then increased again to 26.7% in 2015/16. Adolescents who were aged 18 to 19 years (APR 1.52; 95% CI, 1.38 to 1.68) married or cohabiting with their partners (APR 2.15; 95% CI, 1.93 to 2.40; P<.001), widowed/divorced/separated (APR 2.32; 95% CI, 2.03 to 2.66; P<.001), and among those who started sexual activity before 15 years of age (APR 1.20; 95% CI, 1.11 to 1.31; P<.001) were more likely to become pregnant during adolescence. In contrast, adolescents with secondary school education level and above were the least likely to become pregnant (APR 0.62; 95% CI, 0.51 to 0.75; P<.001) compared to those with no formal education. Conclusion: One in four adolescent girls aged 15 to 19 in Tanzania have already started childbearing and despite fluctuation, high rate of adolescent pregnancy persists. Preventive interventions should focus on adolescents with low education level, married/cohabiting with their partners, and who have started sex before 15 years of age. We advocate for the increase of school attendance until high school level to reduce the risk of early pregnancy in adolescents. Furthermore, qualitative studies are crucial to explore reasons for the rising trend of adolescent pregnancy in most zones of Tanzania, particularly between 2010 and 2015/16.

Trends and factors associated with repeated adolescent pregnancies in Tanzania from 2004-2016: evidence from Tanzania demographic and health surveys.

INTRODUCTION: a repeated pregnancy represents a failure of health and social systems to educate and provide the necessary services and skills to ensure adolescent girls do not experience any further unwanted pregnancies during this young age. We aimed to determine trends and factors associated with repeated adolescent pregnancies in Tanzania 2004-2016. METHODS: an analytical cross-sectional study was conducted using secondary data from Tanzania demographic and health surveys of the years 2004-2005, 2010 and 2015-2016 among adolescent mothers aged 15 to 19 years. Data analysis was performed using STATA version 15 and considered the complex survey design. The Poisson regression model was used to estimate prevalence ratios (PR) and 95% confidence intervals for factors associated with repeated adolescent pregnancy. RESULTS: the proportion of repeated adolescent pregnancies increased from 15.8% in 2004/2005 to 18.6% in 2010, then to 18.8% in 2015/2016. Adolescents who delivered their first pregnancy at home (APR: 1.36, 95% CI: 1.03, 1.78) and who started sexual activity before 15 years of age (APR: 1.80, 95% CI: 1.40, 2.31) were likely repeated adolescent pregnancy. In contrast, adolescents who used contraception (APR: 0.52, 95% CI: 0.34, 0.81) had a lower prevalence of repeated adolescent pregnancies. CONCLUSION: the prevalence of repeated adolescent pregnancies has increased and remains unacceptably high. Adolescents who had low education delivered their first pregnancy at home and were non-contraceptive users need to be targeted in policies and programs for the prevention of repeated adolescent pregnancies.

Paternal characteristics associated with low birth weight among singleton births: a hospital-based birth cohort study in northern Tanzania.

INTRODUCTION: low birth weight (LBW) remains a devastating adverse pregnancy outcome in low and middle income countries (LMICs). There is evidence showing that maternal demographic and pregnancy-related characteristics are associated with LBW. Little attention is given to paternal characteristics, which may be associated with a higher risk of LBW. This study aimed to assess the effect of paternal characteristics on LBW among singleton deliveries at Kilimanjaro Christian Medical Centre (KCMC) zonal referral hospital in Kilimanjaro region, northern Tanzania. METHODS: this was a secondary analysis of a hospital-based cohort study from maternally-linked medical birth registry data at KCMC between 2000 and 2018. A total of 47,035 singleton deliveries were included in this study. Data analysis was performed using statistical package for social sciences (SPSS), version 20 (IBM Corp., Armonk, NY). Relative risk and corresponding 95% confidence intervals (CI) were used to determine association between LBW and paternal characteristics using log-binomial regression models, with robust standard errors to account for clustering of deliveries within mothers. RESULTS: the proportion of LBW during the study period was 9.6%. After adjusting for maternal characteristics, higher risk of LBW was among fathers with low education level (RR=1.72, 95% CI: 1.22, 2.41, p=0.002), aged ≤24 years old (RR=1.37, 95% CI: 1.21, 1.55), and those unemployed (RR= 1.11, 95% CI: 1.01, 1.21). Lower risk of LBW was among fathers aged ≥40 years (RR=0.97, 95% CI: 0.88, 1.08), but this association was not statistically significant. CONCLUSION: the study confirmed paternal young age (≤24 years old), paternal low education level and unemployment as predictors for LBW. Current evidence on the effect of paternal characteristics on LBW might suggest that programs and policies should target their engagement as a key strategy for improving birth outcomes during the perinatal period. Future studies should assess how paternal factors are associated with the risk of adverse birth outcomes.

Community engagement in COVID-19 prevention: experiences from Kilimanjaro region, Northern Tanzania.

Prevention of exposure to the COVID-19 virus in the general population is an essential strategy to slow community transmission. This paper shares the experiences and challenges of community engagement in COVID-19 prevention in the Kilimanjaro region, Northern Tanzania implemented by our team from the Institute of Public Health (IPH), Kilimanjaro Christian Medical University College (KCMUCo) in collaboration with the COVID-19 response team in the Moshi Municipality. We conducted an education session with the COVID-19 response team and together brainstormed transmission hotspots and which interventions would be most feasible in their settings. The first hotspot identified was crowded local market spaces. Suggested interventions included targeted and mass public health education through the engagement of market opinion leaders, public announcements, and radio shows. We conducted participatory rural appraisal techniques to enable market vendors and clients to visualize two-meter distances and provided a prototype hand-washing facility that was foot operated. We found mass public health educational campaigns essential to inform and update the public about COVID-19 pandemic and to address rumors and misinformation, which hampers compliance with public health interventions. Coordinated efforts among stakeholders in the country are necessary to develop context-specific prevention and case management strategies following the national and international guidelines. Local ownership of recommended interventions is necessary to ensure compliance.
