Prevalence and factors associated with modern contraceptives utilization among female adolescents in Uganda

Adolescence is a crucial period during which many begin sexual activity [1, 2]. Globally, the sexual and reproductive health (SRH) needs of adolescents have remained largely unmet with about 20 million female adolescents aged 15–19 years in need of modern contraceptive methods [3]. Sub-Saharan Africa has the highest rates of adolescent pregnancy and the lowest utilization of modern contraceptives [1, 2, 4]. A third of adolescent pregnancies in Sub-Saharan Africa are unintended, with over a third of these unintended pregnancies being unwanted and end up as unsafe terminations [1, 4]. Pregnancy and childbirth related complications are the leading causes of maternal death among female adolescents aged 15–19 in low and middle-income countries (LMICs) [5, 6]. Adolescent pregnancy and childbirth is associated with other poor health outcomes such as anemia, preterm birth, low birthweight, adverse adolescent mental health effects, besides its negative effects on higher education attainment and job opportunities [1, 2, 7‐10].

Use of modern contraceptives reduces maternal mortality, improves health outcomes of adolescent mothers and their children and reduces the costs associated with teenage pregnancy [5, 11]. Planned childbirths increase the likelihood of attaining higher educational levels, which results in financial independence [12‐14]. Despite the global progress in increasing availability and coverage of family planning services, [5, 15] most of the contraceptive needs of adolescents are largely unmet [1, 5, 11]. Uganda’s adolescent fertility rates are among the highest in the world [13, 16, 17]. According to the latest Uganda Demographic and Health Survey (DHS), 24.8% of girls aged 15–19 had already begun childbearing [18]. Furthermore, Uganda has one of the lowest contraceptive prevalence rate in the region [16]. The high numbers of adolescents giving birth at an early age partly contributes to Uganda’s high fertility levels [19].

The Government of Uganda through the ministry of Health and its development partners have come up with different initiatives to ensure improved distribution, access and utilization of contraceptives, however, the contraceptive prevalence rate remains low while the unmet need is high [13, 20]. Studies in Uganda have focused mainly on knowledge, attitudes and barriers to access among older women and others have been predominantly qualitative in nature [13]. For Uganda’s health system to effectively respond to the high and increasing population of adolescents, its crucial to understand the predictors of modern contraceptive utilization among female adolescents. This study aimed at describing factors associated with utilization of modern contraceptives among female adolescents aged 15–19 years. Its recommendations will help in improving implementation of programs focusing on the reproductive health needs of female adolescents in Uganda, which with better health, this will increase their contribution to the development of the country.

This study investigated the prevalence and factors associated with modern contraceptive utilization among Ugandan female adolescents aged 15–19 years. Prevalence of modern contraceptive utilization was 9.4% (95% CI: 8.6–10.3). This is very low and negatively affects Uganda’s progress of achieving sustainable development goal (SDG) 3 target 3.7 aimed at ensuring universal access to sexual and reproductive health-care services, including for family planning by 2030 [26]. With low contraceptive utilization, and with Uganda having some of the highest adolescent fertility rates in the region, these findings imply that a lot has to be done to ensure increased access and utilization of contraceptives as one of the ways of reducing teenage pregnancies and the associated morbidity and mortality if we are to meet the SDG targets as a country.

Our study in comparison to other studies showed that contraceptive utilization in Uganda is lower than that of Kenya, Rwanda, Tanzania, Europe, Latin America and United States of America [1, 5, 16, 27‐29] and higher than that in Nigeria [30]. The higher prevalence in Kenya can be attributed to the increased funding of policies and interventions being implemented by the Kenyan government compared to Uganda [1, 16]. Compared to Uganda, Rwanda’s small population size and the large population density might have contributed to the government’s faster success in implementation of family planning programs [1, 31]. Furthermore, use of government supported community health workers in providing short term methods in the community and the widely utilized community based health insurance program have increased accessibility to modern contraceptives [1, 16, 32, 33]. Although most young women in Kenya and Rwanda get their modern contraceptives from the free public sector facilities, most of the young women in Uganda access contraceptives from private sources with out-of-pocket expenditures [1, 2, 34]. This could as well contribute to the observed lower prevalence rate in Uganda. The modern contraceptive utilization rates in Europe and Latin America are approximately 50% [28] and 30% [5] respectively which are much higher than what we observed in our study. One of the reasons that can explain this is the higher gender equality in Europe which makes women empowered to make decisions regarding contraceptive use [28]. Another explanation could be the higher affluence in Europe compared to Uganda [28]. Adolescents belonging to affluent families could easily access contraceptives through private or public facilities.

The prevalence of contraceptive utilization among the adolescents in our study was lower than that in the older UDHS 2016 participants [22]. Furthermore, Li et al. analyzed 261 DHS and Multiple Cluster Indicator Surveys’ datasets from 103 low- and middle-income countries between 2000 and 2017 showed that adult women aged 20 to 34 years had higher average contraceptive rate of 43.5% which is way higher compared to the finding in our study [35]. The lower utilization rate among adolescents could be attributed partly to the financial constraints of accessing the contraceptives, poor contraceptive knowledge, and limited availability of adolescent friendly health services [35].

Married adolescents were more likely to utilize modern contraceptives compared to unmarried adolescents. Married adolescents are more likely to afford contraceptives compared to their unmarried counterparts due to partner support [36]. Marital status has been shown to be associated with modern contraceptive use in other countries [36‐38].Women whose age at first birth was less than 15 years were more likely to utilize modern contraceptives compared to those whose age at first birth was greater than 15 years. This might indicate improved health seeking behavioural which unfortunately comes in later after they have had a birth at a younger age [19]. Furthermore, adolescents that give birth at a younger age are more likely to utilize health facilities for antenatal care, delivery and post-natal care services [22] hence increased exposure to family planning counselling. Age at first birth has been shown to be associated with modern contraceptive utilization in similar studies [19, 39].

Adolescents belonging to the Central region were more likely to utilize modern contraceptives compared to those in the Northern region. The observed regional differences in utilization of modern contraceptives could be attributed to the differences in access to modern contraceptives, sociocultural contexts and job opportunities available to adolescents in the different regions [40]. Most of the young women in Uganda access contraceptives from private sources with out-of-pocket expenditures [1, 2]. Central region unlike the Northern region is the central business region and home to the capital city hence more economically developed with a higher concentration of health facilities, economic opportunities and access to SRH mass communication means such as radios, newspapers [41‐43]. All these factors enable easier access and affordability of modern contraceptives and also increase the probability of access to family planning information. Regional differences have similarly been shown to be associated with contraceptive use in various studies [19, 44‐46].

Adolescents belonging to the poorest wealth quintile were less likely to utilize modern contraceptive methods compared to those belonging to the middle wealth quintile. Most of the young women in Uganda access contraceptives from private sources with out-of-pocket expenditures [1, 2, 34]. Hence the poor are more likely to have limited access to modern contraceptives due to the out of pocket expenditures to purchase the contraceptives or transport expenditures to free public health facilities [19, 47]. The poor are less likely to be well informed about family planning which can be attributed to the low education levels, less likelihood to own radios, television sets, mobile phones or buy newspapers which limits the likelihood of getting family planning information to enable them make informed healthy choices [39, 48‐50]. Wealth has been shown to be associated with modern contraceptive use in other studies [19, 49, 51].

The findings of this study highlight the influence of age at first birth, region, wealth index and marital status as key predictors of contraceptive use among female adolescents in Uganda. The findings further show a need to promote the availability, accessibility and acceptability of modern contraceptives among female adolescents, especially those that reside in the rural areas who are likely to be poorer. Different stakeholders should design targeted and peer mediated interventions due to differences in adolescents according to their wealth index, regions and marital status.
