1.1 Introduction
Unplanned pregnancy describes a pregnancy that is either mistimed, meaning it occurs earlier than desired, or unwanted, which occurs when a pregnancy is not desired at all. Unplanned pregnancies are often associated with a lack of access to contraception or inadequate knowledge about reproductive health (Santelli et al., 2017). Unplanned teenage pregnancy remains a pressing public health concern worldwide, especially in developing countries. The complexities of early pregnancy often have profound effects on the educational, social, and economic prospects of young people, particularly teenage girls. Studies have shown that teenage pregnancies are associated with higher dropout rates, increased health risks, and social stigma, which ultimately hinder young people from realizing their full potential (World Health Organization, 2021).
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
The development of sex education as a means to prevent unplanned pregnancies among teenagers has evolved significantly over the past century. Early sex education efforts in the early 20th century primarily focused on moral instruction, aimed at discouraging premarital sex rather than providing comprehensive knowledge about reproductive health (Irvine, 2002). During this period, sex education often emphasized abstinence and was driven by societal norms rather than empirical research, limiting its effectiveness in preventing teenage pregnancies.
In the 1960s and 1970s, as attitudes toward sexuality became more liberal, there was a growing recognition of the importance of addressing teenage pregnancy as a public health issue. This period saw the rise of more progressive sex education programs that included information on contraception and reproductive health as part of a broader public health agenda (Luker, 2006). Research during these decades began to demonstrate that access to contraceptive information and services reduced the rates of teenage pregnancy, leading many schools and organizations to advocate for more comprehensive sex education (Kirby, 2008).
In recent years, comprehensive sex education has gained wider acceptance as the preferred approach to teenage pregnancy prevention. Research consistently supports the effectiveness of these programs, with the WHO (2021) affirming that comprehensive sex education can help adolescents develop healthy sexual behaviors, reduce risky activities, and prevent unplanned pregnancies. As society continues to recognize the importance of informed sexual health education, comprehensive programs remain at the forefront of preventing teenage pregnancy globally.
The prevalence of unplanned teenage pregnancies is a significant concern globally, with an estimated 21 million girls aged 15–19 years becoming pregnant each year, many of whom lack access to adequate sexual and reproductive health information (UNICEF, 2022). These pregnancies often result from a combination of factors, including inadequate knowledge about contraception, socio-cultural pressures, and limited access to healthcare services. According to the Centers for Disease Control and Prevention (CDC, 2020), unplanned pregnancies among teenagers are linked to a variety of adverse outcomes, including higher rates of school dropout, economic dependency, and health risks for both the mother and child.
Sex education refers to the process of educating individuals about human sexuality, including topics such as sexual anatomy, reproduction, sexual behavior, relationships, and the importance of consent. Comprehensive sex education encompasses information on contraception, sexually transmitted infections (STIs), and the development of interpersonal skills to make informed decisions (World Health Organization, 2021). One of the most effective approaches to curbing teenage pregnancy is through comprehensive sex education, which equips young people with the necessary knowledge, attitudes, and skills to make informed decisions about their sexual health.
Sex education has been widely advocated as a preventive tool, promoting informed decision-making and empowering teenagers to avoid risky sexual behaviors. Comprehensive sex education, as defined by Haberland and Rogow (2015), is an approach that goes beyond basic biological facts to include communication skills, understanding consent, and recognizing healthy relationships. Studies have consistently shown that teenagers who receive comprehensive sex education are more likely to delay sexual activity, use contraception, and avoid unintended pregnancies (Kirby, 2008). Despite these findings, debates over the content and delivery of sex education programs continue, with some advocating for abstinence-only approaches. However, research suggests that abstinence-only programs may not be as effective in preventing teenage pregnancies, as they often omit critical information on contraception and safe sex practices (Santelli et al., 2017). The need for a balanced curriculum that educates young people on all aspects of sexual health is therefore essential.
Therefore, in Nigeria where the research was carried out, the activities that was conducted is to know the impact of sex education in preventing unplanned pregnancy among teenagers.
1.3 Statement of Problems
Investigation revealed that unplanned teenage pregnancies remain a significant public health issue, affecting the lives of young people and placing a strain on healthcare, education, and social systems. Research indicates that teenagers often lack the necessary knowledge to make informed decisions about their sexual health, which increases the likelihood of unprotected sex and, consequently, unintended pregnancies (Santelli et al., 2017). Inadequate or inaccessible sex education is one of the primary factors contributing to these outcomes, leaving many teenagers without a comprehensive understanding of reproductive health, contraception, and safe sexual practices (UNICEF, 2022).
Despite evidence supporting comprehensive sex education, many schools and communities rely on abstinence-only programs that limit essential information about contraception and healthy relationships (Kohler et al., 2008). Furthermore, cultural and societal taboos surrounding discussions of sex education hinder the implementation of comprehensive programs, leaving many adolescents with misconceptions and incomplete information about sexual health (World Health Organization, 2021). It is against the backdrop that this study seeks to address these problems by evaluating the impact of sex education in preventing unplanned pregnancy among teenagers.
