1.1 Introduction
Teenage pregnancy is defined as pregnancy occurring in girls aged between 13 and 19 years, a developmental stage characterized by significant physical, emotional, and social transitions (World Health Organization, 2023). It is widely recognized as a major public health concern due to its association with increased risks of maternal and neonatal complications, as well as its long-term social and economic consequences for young mothers and their families. In many developing countries, including Nigeria, teenage pregnancy remains prevalent despite ongoing awareness campaigns and reproductive health interventions.
In Nigeria, teenage pregnancy is influenced by a combination of socio-economic, cultural, and behavioral factors. According to the Nigeria Demographic and Health Survey, a significant proportion of adolescent girls begin childbearing before completing secondary education, particularly in urban and semi-urban areas where poverty levels and limited access to reproductive health education remain high (National Population Commission and ICF, 2019).
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are significance of the study, scope of work, research hypothesis and questions, limitation of the study and definition of terms.
1.2 Background of Study
Teenage pregnancy remains a major public health and developmental challenge across many low- and middle-income countries, particularly in sub-Saharan Africa where socio-economic inequalities, cultural practices, and limited access to reproductive health services continue to shape adolescent reproductive outcomes. According to the World Health Organization (WHO), teenage pregnancy refers to pregnancy occurring in females aged 13 to 19 years and is associated with increased risks of maternal morbidity, mortality, and adverse neonatal outcomes. WHO further reported that adolescent mothers are more likely to experience complications such as obstructed labour, preeclampsia, and unsafe abortion-related conditions compared to older women (WHO, 2023).
According to the United Nations Population Fund (UNFPA, 2022), teenage pregnancy is not only a health issue but also a socio-economic concern that affects educational attainment, poverty levels, and gender inequality. UNFPA stated that millions of adolescent girls worldwide become pregnant each year, with a significant proportion of these pregnancies being unintended. The organization affirmed that early childbearing often results in school dropout, reduced employment opportunities, and long-term cycles of poverty that affect both the mother and child.
In Nigeria, teenage pregnancy remains highly prevalent and varies across regions due to cultural, religious, and socio-economic differences. According to the National Population Commission and ICF (2019), a significant percentage of girls aged 15 to 19 years have begun childbearing, especially in rural and urban slum communities. The report asserted that early sexual initiation, low contraceptive use, and limited access to reproductive health education are key contributing factors to the high rate of teenage pregnancy in the country. It further contends that socio-cultural norms that encourage early marriage in some communities also play a significant role in increasing adolescent pregnancy rates.
Guttmacher Institute (2020) stated that, adolescent girls in developing countries are disproportionately affected by unintended pregnancies due to inadequate sexual education and restricted access to contraceptive services. The institute reported that lack of youth-friendly health services discourages teenagers from seeking reproductive health care, thereby increasing their vulnerability to unplanned pregnancies and unsafe abortion practices. It further affirmed that improving access to comprehensive sexuality education significantly reduces the incidence of teenage pregnancy.
In the context of healthcare delivery in Nigeria, Warri Central Hospital serves as a key referral and primary healthcare facility for adolescent reproductive health cases in its catchment area. According to clinical observations and hospital-based reports, teenage pregnancy cases have remained consistently high, often presenting with complications that require specialized obstetric care. These include anaemia, hypertensive disorders, prolonged labour, and in severe cases, maternal and neonatal mortality risks. The hospital data suggests that many of these cases are linked to late presentation for antenatal care and inadequate awareness of pregnancy-related risks among adolescents.
Okonofua et al. (2019) asserted that, adolescent pregnancy in Nigeria is strongly influenced by poverty, low educational attainment, and limited access to reproductive health services. The authors reported that girls from low-income households are more likely to engage in early sexual activity due to economic vulnerability, sometimes leading to transactional sex. They affirmed that this increases the likelihood of unintended pregnancies and exposure to sexually transmitted infections. They further contended that community-level interventions focusing on education and empowerment are essential in reducing teenage pregnancy rates.
Akinyemi and Fatusi (2021) affirmed that, peer pressure and lack of parental supervision significantly contribute to risky sexual behaviours among adolescents in Nigeria. The authors stated that many teenagers lack adequate guidance on reproductive health matters, which exposes them to misinformation and unsafe sexual practices. They further affirmed that cultural silence around sexual health discussions between parents and children contributes to the persistence of teenage pregnancy.
According to UNICEF (2022), teenage pregnancy has far-reaching consequences on both maternal and child health outcomes. UNICEF reported that children born to teenage mothers are more likely to suffer from low birth weight, preterm birth, and higher infant mortality rates. The organization affirmed that adolescent mothers themselves face higher risks of mental health challenges, including depression and anxiety, especially in cases of unplanned or stigmatized pregnancies.
This study is set against the backdrop of the increasing prevalence of teenage pregnancy, the associated risk factors, and the complications observed among patients at Warri Central Hospital, with the aim of contributing to improved understanding and evidence-based interventions for adolescent reproductive health in the study area.
1.3 Statement of Problems
Investigation revealed that teenage pregnancy remains a persistent public health and socio-economic challenge, particularly in developing countries such as Nigeria, where it continues to affect the wellbeing, education, and future opportunities of adolescent girls. The World Health Organization (WHO, 2023) identifies teenage pregnancy as a major contributor to maternal and neonatal complications, especially in low-resource settings where access to reproductive health education and services is limited. In Nigeria, the prevalence remains concerning, with the Nigeria Demographic and Health Survey reporting that a significant proportion of girls aged 15 to 19 have either begun childbearing or are already mothers (National Population Commission and ICF, 2019).
In the study area, healthcare professionals continue to observe increasing cases of teenage pregnancy, many of which present with preventable complications such as obstructed labour, anaemia, preeclampsia, unsafe abortion complications, and psychological distress. Additionally, many of the affected teenagers are often school dropouts or girls with limited access to sexual and reproductive health education, which increases their vulnerability to early sexual initiation and unintended pregnancy (UNFPA, 2022).
Furthermore, socio-cultural factors such as early marriage, peer pressure, poverty, and inadequate parental guidance continue to influence the prevalence of teenage pregnancy in communities served by Warri Central Hospital. In many cases, adolescents lack accurate information about contraception and reproductive health services, while societal stigma discourages them from seeking timely medical care. It is against this backdrop that this study seeks to examine the prevalence, risk factors, and complications of teenage pregnancy among patients at Warri Central Hospital.
1.4 Aim and Objectives of Study
