1. Introduction
The world is experiencing the largest cohort of adolescents in history [
1], with a significant proportion of the global population being between the ages of 10 years and 19 years [
2,
3]. Despite the awareness that maintaining sexual health in adolescence essentially contributes to reproductive health and well-being in later life [
4,
5], challenges remain in ensuring access to it. Socio-cultural and gender norms continue to affect both sexes as they navigate their transition to adulthood. Currently, 88% of the 1.2 billion adolescents worldwide live in developing countries where universal access to SRH is yet to be realised and these adolescents face a higher unmet need for SRH services, as well as a higher burden of unplanned pregnancies and contracting sexually transmitted infections (STIs) than their peers in the developed world [
3,
6].
This may be due to cultural barriers, cost of service, poor provider attitude, and absence of special “adolescent only” services [
7,
8] that do not encourage pregnant adolescents to access antenatal care [
8,
9,
10,
11,
12,
13,
14,
15].
Many adolescents engaging in sex for the first time hardly use any form of protection [
6,
16,
17,
18] due to casual, impulsive, and unplanned sexual activity among them [
19,
20]. Adolescents who had an early sexual debut are likely to have multiple partners, thereby increasing their risk of contracting STIs and the risk of unplanned pregnancy [
1].
The need for adequate attention towards adolescents’ SRH remains critical. Efforts to attain quality SRH are constrained by inadequate access and inequitable distribution of SRH services, resulting in the poor utilisation of SRH services among young people in sub-Saharan African countries. Prior studies show that adolescents across the world face barriers such as long waiting hours, negative provider attitudes, unnecessary restrictions, lack of privacy and confidentiality, social-cultural norms, and stigma when accessing health services [
14,
21]. There remains a need for relevant data to understand and substantiate the needed interventions [
22,
23,
24].
In Ghana, adolescent health is a priority health issue [
25,
26]. Adolescent- and youth-friendly health services have been identified as a strategy for improving adolescent access to and utilisation of SRH services in the country. Despite its suitability and progress towards improved Sexual and reproductive health and rights (SRHR), outcomes among adolescents are not as expected [
27]. The Government of Ghana, through the Ministry of Health and related departments and agencies, has developed several adolescent- and youth-related policy documents and standards, such as the Adolescent Reproductive Health Policy, National HIV/AIDS and STIs Policy, National Health Policy, the Children’s Act (1998), and the Juvenile Justice Act (2003), among others, to support adolescent health. In addition, Ghana ratified several international conventions that promote and protect the well-being of adolescents and youth, such as the United Nations Convention on the Rights of the Child, while the Ghana Health Service (GHS) promotes youth-friendly services. These initiatives, however well-planned, have also not yielded the desired outcome [
15] because Ghanaian adolescents still underutilised SRH services, mainly due to stigma around premarital sex [
5,
28,
29,
30,
31], while over 750,000 adolescents become pregnant annually [
31].
The challenges of adolescent inaccessibility of SRH services in Ghana have been identified as being due to barriers such as cost of services, lack of awareness about where to obtain contraceptives and STI treatment, misconception about side effects of contraceptives, lack of confidentiality and privacy [
32,
33], and negative provider attitudes [
14,
15,
26,
27,
28,
29,
30,
31]. Currently, urbanisation, changes in social norms, and shifting trends in marriage and sexual activity reflect the world in which adolescents are growing [
34].
Although there have been many studies on adolescent SRH in Ghana, very few have focused on trends in the utilisation of SRH services among female adolescents nationwide. This study utilises secondary data collected from nationally representative cross-sectional surveys to examine the use of sexual and reproductive health services by adolescents (15–19 years) in Ghana from 2007 to 2017. The findings seek to inform efforts by the government of Ghana to improve and expand access to adolescent SRH services and appropriately respond to common and new barriers to attain optimum SRH.
2. Materials and Methods
2.1. Study Type
The study was a secondary data analysis of the 2007 and 2017 Ghana Maternal Health Surveys (GMHSs). These were nationally representative surveys among women in the reproductive age of 15–49 years, designed to produce representative estimates for maternal mortality indicators for the country and for each of the three geographical zones, namely Coastal, Middlebelt, and Northern sectors. The Ghana Maternal Health Survey (GMHS) is a household-based survey, which utilises a two-stage sample design. In the 2007 Maternal Health Survey, the first stage involved the selection of samples from a master sampling frame constructed from Enumeration Areas (EAs) from the Ghana Population and Housing Census 2000. The 2017 Maternal Health Survey sampling frame was also based on the Enumeration Areas of the 2010 Ghana Population and Housing Census. The second stage involved the systematic sampling of the households listed from each cluster to ensure an adequate number of completed individual interviews was obtained [
35]. The Survey collected data through an interviewer-administered structured questionnaire based on the DHS programme model. Three questionnaires were utilised for the GMHS, as follows: the household, women’s, and verbal autopsy questionnaires. All women aged 15–49 years were eligible to be interviewed from each selected household. For this study, responses from the women’s questionnaire were utilised.
2.2. Data Extraction
For this study, only female adolescents aged 15–19 years were included in the analysis. The Ghana Maternal Health Survey data for 2007 had 10,370 respondents aged 15–49 years, while that of 2017 had 25,062 respondents. Based on the criteria for adolescent females, the number of respondents selected was 2056 for 2007 and 4909 for 2017.
2.2.1. Inclusion Criteria
All female adolescents from the age of 15 to 19 years.
2.2.2. Exclusion Criteria
All female adolescents aged 15–19 years with incomplete responses were excluded from the analysis.
2.3. Measures
The outcome variable was the utilisation of SRH services, defined as the use of family planning and abortion services.
Utilisation of family planning was a direct Yes/No question “Are you currently using any method?” coded as Yes = 1 and No = 0, respectively.
Family planning methods were classified as modern or traditional methods and recorded. Modern methods include pills, injectables, implants, male condoms, female condoms, intrauterine devices (IUDs), and emergency contraception. Traditional methods also included the withdrawal method, rhythm method, and abstinence.
Utilisation of abortion services was measured by the respondents indicating whether they had used safe or unsafe facilities in response to the following question: “What was the source of the last step to end pregnancy”. This was recorded as facility type. Based on the criteria set by the Ghana Comprehensive Abortion Care Services Protocol (2012), all hospitals, clinics, and health centres, both public and private, were classified as safe, while private pharmacies, chemical and drug stores, and respondents’ homes were classified as unsafe facilities. Utilisation was thus recorded as a binary variable.
Provider of the last step to end pregnancy was recorded as provider type. Providers like doctors, midwives, and nurses are classified as trained; all others, like community health workers, pharmacists, chemical sellers, traditional practitioners, relatives, and friends, were classified as untrained providers. These classifications were all based on the Ghana Comprehensive Abortion Care Standards and Protocols (2012). Independent variables were age, knowledge level, education, sexual activity, and age at first sex.
Knowledge level was a composite variable derived from the response (yes or no) to the following four questions: “Have you heard of family planning method”, “Do you know the source of family planning”, “have you ever heard about abortion”, and “do you know where to get abortion”.
Sexual activity was binary (yes = 1 or no = 0), following the question: “Have you ever had sex?”. Age at first sex was a follow-up question to sexual activity, by asking the respondent, “What age did you engage in sex?” Responses were captured in single ages.
2.4. Data Analysis
Descriptive statistics were used to describe the characteristics of the study participants. This was presented in percentages using frequency tables. Bivariate analysis was carried out using Pearson’s chi-squared test to assess the relationship between independent variables and the utilisation of SRH. Multivariate logistic regression was used to examine the strength of the relationship with SRH utilisation. The odds ratio and the associated 95% confidence intervals were used to assess the strength of the association. A p-value of 0.05 was used to determine statistical significance. All statistical analyses were conducted using Stata SE version 15.
4. Discussions
The findings of this study show that the utilisation of family planning services remains challenging, as the proportion of adolescents using FP showed a decline from 2007 to 2017, despite the interventions and efforts undertaken by programs in the country. This low utilisation has frequently been reported among adolescents in Ghana [
8,
36,
37,
38]. The study also found that over the period under review, adolescents who knew a source of FP were more likely to have utilised FP services less, even though 2017 showed a slight improvement compared to 2007. This finding critically highlights the little progress made in responding to the underutilisation of SRH services among adolescents [
38]. Challenges in increasing the utilisation of SRH services remain within the Ghanaian healthcare system and the negative health implications continue to be recorded. It is critical to identify novel opportunities to encourage its utilisation, to respond appropriately to this challenge in Ghana [
25,
39].
This study revealed that adolescents’ knowledge about family planning services was low in 2007 but had increased in 2017. These findings, though consistent with findings from other SSA countries and multi-country studies [
16,
22,
40], could be a reflection of adolescents’ negative attitudes towards SRH due to cultural barriers, lack of confidentiality at health facilities, fear of side effects, inadequate peer support, and poor provider attitudes as evident from both global and local studies [
2,
9,
19,
41]. The lack of comprehensive information on reproductive health issues and services makes adolescent girls vulnerable to unsafe reproductive health behaviour [
34,
42]. It is plausible that the improvements identified in Ghanaian adolescents in 2017 can be attributed to the interventions towards improved adolescent SRH services [
15,
25].
This study, however, reported a high knowledge of abortion services among respondents. The proportion of respondents with a knowledge about abortion services in 2007 increased to 90.4% in 2017. A similar pattern was observed concerning the knowledge of a source for abortion services, indicating that adolescents have an increased access to information on this issue [
34]. Although this study did not access information sources among adolescents, it is important to explore the sources to assess their validity, since many are unable to seek accurate information from the right source [
8,
14].
Regarding abortion, 43.1% of respondents in 2007 patronised safe facilities, yet, in 2017, it reduced to 32.8%. Similarly, utilisation of the services of a trained professional reduced from 43% in 2007 to 35.2% in 2017, a disturbing trend, suggestive of the increased use of untrained workers. The increase in unsafe abortion, despite the increased awareness and creation of campaigns on safe abortion, could be due to barriers such as cost of services, proximity to services, lack of confidentiality, and privacy [
2,
26,
27,
28,
29,
34,
43,
44]. Most adolescents feel uncomfortable accessing services of the various components of SRH services in facilities [
13,
32,
40,
45]. The multivariate analysis showed a significant association between age at first sex among sexually active adolescents.
The recorded increase in the odds of modern method use from 2007 to 2017 is noteworthy. Many studies identify that the preferred modern method for adolescents is condoms [
8,
11,
36,
37,
38,
46,
47,
48]. It is plausible that among adolescents who are exposed to information on family planning and contraceptive use, many adolescents opt for the condom because it is cheaper and easily accessible and serves as dual protection [
8,
10,
38], compared to others such as injectables, implants, and intrauterine devices (IUDs). The reduced utilisation of methods that serve pregnancy prevention only roles, but require visitation to health facilities with its associated negative health worker attitudes, inherently acts as a deterrent to adolescents in need [
19,
28,
37].
The multivariate analysis showed a significant association between age at first sex and the utilisation of family planning services. This finding, however, is inconsistent with findings from other studies that revealed that adolescents who initiate sex early are not likely to use family planning methods, which exposes them to the risk of getting pregnant [
8,
40]. It is plausible that the shift in attitude towards accepting the use of family planning methods is a product of the multiple interventions introduced to improve its utilisation in Ghana [
26]. Evidence suggests that older adolescents are likely to be sexually active and, therefore, more likely to utilise SRH services [
24,
28,
29]. With knowledge as a precursor to action, they may have more access to SRH services.
This study, though nationally representative, is not without its limitations. First, as the study relied on secondary data, this limited our analysis to the variables that had been collected. This study is also cross-sectional and, hence, causal inferences cannot be made. Finally, the study relied on self-reported measures from adolescents, which are subject to recall bias.
