abstract: 'Objective Understanding the determinants of adolescent pregnancy and how
|
|
|
|
they have changed over time is essential for measuring progress and
|
|
|
|
developing strategies to improve adolescent reproductive health. This
|
|
|
|
study examined changes over time in the prevalence and determinants of
|
|
|
|
adolescent pregnancy in Ghana.
|
|
|
|
Methods A total of 11 nationally representative surveys from the Ghana
|
|
|
|
Demographic and Health Survey (1988, 1993, 1998, 2003, 2008, 2014),
|
|
|
|
Multiple Indicator Cluster Survey (2006, 2011, 2017-2018) and Malaria
|
|
|
|
Indicator Survey (2016 and 2019) provided data on 14556 adolescent girls
|
|
|
|
aged 15-19 for this analysis. A random-effect meta-analysis, time trends
|
|
|
|
and multivariable logistic regression models were used to track the
|
|
|
|
prevalence and determinants of adolescent pregnancy.
|
|
|
|
Results The pooled prevalence of adolescent pregnancy in Ghana was
|
|
|
|
15.4\% (95\% CI=13.49\% to 17.30\%). Rural areas (19.5\%) had a higher
|
|
|
|
prevalence of adolescent pregnancy than urban areas (10.6\%). In the
|
|
|
|
overall sample, middle adolescents (15-17 years) (aOR=0.30, 95\% CI=0.23
|
|
|
|
to 0.39), adolescents in urban areas (aOR=0.56, 95\% CI=0.43 to 0.74),
|
|
|
|
large households (aOR=0.62, 95\% CI=0.49 to 0.78), not working
|
|
|
|
(aOR=0.62, 95\% CI=0.43 to 0.90) and those unaware of contraceptive
|
|
|
|
methods (aOR=0.49, 95\% CI=0.27 to 0.90) were less likely to become
|
|
|
|
pregnant. Adolescents from middle-income (aOR=0.91, 95\% CI=0.67 to
|
|
|
|
1.24) or high-income (aOR=0.59, 95\%CI=0.36 to 0.94) households, those
|
|
|
|
who were semiliterate (aOR=0.56, 95\%CI=0.39 to 0.82) or literate
|
|
|
|
(aOR=0.28, 95\%CI=0.21 to 0.37) and those with fewer previous sex
|
|
|
|
partners were less likely to become pregnant. Not all determinants in
|
|
|
|
the overall sample were consistently associated with adolescent
|
|
|
|
pregnancy in the last three decades. Between 1988 and 1998, determinants
|
|
|
|
of adolescent pregnancy were age, literacy, employment, household size
|
|
|
|
and whether the mother was alive. Between 2003 and 2008, age, literacy,
|
|
|
|
household size, income, age of last sexual partner, number of previous
|
|
|
|
partners and contraception knowledge determined adolescent pregnancy.
|
|
|
|
From 2011 to 2019, age, residence, literacy and menstrual cycle
|
|
|
|
knowledge were determinants of adolescent pregnancy.
|
|
|
|
Conclusion Interventions and policies to prevent adolescent pregnancy
|
|
|
|
should prioritise adolescents from disadvantaged backgrounds.'
