Around the world, young women experience a high rate of unwanted pregnancies and abortions due to their limited knowledge of sexual and reproductive health. Family planning (FP) knowledge and use are important indicators of sexual and reproductive health among young people, especially in African regions [1]. Young people represent 24% of the population in the world, and 32% in 2019 in Cameroon [2]. Adolescence is the period of growth and human development that occurs between childhood and adulthood, that’s the ages from 10 to 19 years [3]. Many adolescents are pressured into having sex, which puts them at very high risk of unwanted pregnancies [3]. Family planning (FP), is one of the components of reproductive health, which allows individuals and couples to avoid unwanted pregnancies, decide on the timing of pregnancies and the number of children they want [4].

Since the 1970s, the WHO with the support of the United Nations Fund for Population Activities (UNFPA) has been actively involved in the promotion of adolescent sexuality and reproduction [5].

In Cameroon, according to the 2018 demographic and health survey (DHS V) [6], 24% of adolescent girls had started their reproductive life, of which 5% were pregnant with a first pregnancy and 19% had at least a child. The percentage of adolescent girls who have already begun their reproductive life increases rapidly with age, rising from 4% at age 15% to 23% at age 17 and then to 49% among those aged 19 [6]. A study on the unmet needs for family planning among adolescent could contribute to the search solutions to improve access to effective methods of contraception, in other to contribute to achieving the third goal of sustainable development, which is to empower people to lead healthy lives and support the well-being of all at all ages [7]. Our general objective was to assess the unmet needs for FP among adolescent girls who give birth, specifically to describe the socio-obstetric profile, determine the frequency of use of contraceptive methods and identify unmet needs for contraception.

The study was descriptive cross-sectional, lasting 5 months, from February 1 to June 30, 2020 in 3 hospitals in the city of Yaoundé: Yaoundé Central Hospital (YCH), Yaoundé Gyneco-Obstetrics and Pediatric Hospital (YGOPH) and Biyem-Assi District Hospital (BDH). These hospitals (among which the first 2 are reference hospitals) perform between 300 and 350 deliveries per month, which allowed us to reach our minimum sample size.

The study population consisted of adolescents who gave birth in the hospitals mentioned. Sampling was consecutive and exhaustive. Included were all teenage mothers speaking English or French. Excluded were any adolescent who refused consent, or whose parent did not give consent, or who withdrew consent during the study, and/or whose information was incomplete for the data analysis. The minimum size of our sample was estimated using the Lorenz formula and ended up recruiting is 157 participants.

After obtaining the authorizations, we went to the various maternities. From the registers of the delivery room, we identified the names of the mothers and their ages, in order to extract the names of the adolescent girls. We then spotted them in the postpartum wards. After consent, we proceeded to recruitment. Hospital records were consulted when necessary to complete the information. Data consisted of continuous and categorical variables of sociodemographic information and knowledge and use of contraceptives. All the information collected was reported on previously established, tested and adapted technical sheets.

The data collected on the technical sheets were entered using CSPro 7.3 software and analyzed with Excel 2010 and SPSS version 23.0 softwares. Tools used to express our results were frequency and mean. Odds ratio (OR) and the p were used to find the association between the different variables studied and the unmet FP needs. p was considered significant for any value less than 0.05.

We obtained ethical clearance from the Institutional Ethics Committee for Research in the Human Sciences of the University of Douala. Written informed consent was requested from all participants and their parents.

From February 1 to June 30, 2020, we recorded a total of 2692 deliveries, of which 188 (7%) were from adolescents. Of these, 157 fulfilling our selection criteria and were recruited and data analyzed.

The average age of the participants was 17.9 ± 1.12 years with extremes of 13 and 19, the average gravidity was 1.2 ± 0.5 with extremes of 1 and 3, and the average parity was 1.2 ± 0.4 with extremes of 1 and 3. The socio-demographic and obstetrical profile of the participants is shown in Table 1. Among the 157 participants, 155 (98.7%) were between 15 and 19 years old, 135 (86%) were Christians, 124 (79%) were unmarried, 156 (99.4%) were in school, 155 (98.7%) had partners attending school. One hundred and thirty-two (84.1%) lived in urban areas, 62 (39.4%) were from the Center Region and 44 (28%) from the West. One hundred and thirty-two (84.1%) had a gravidity of 1, and 136 (86.6%) had a parity of 1. Of the 156 educated female participants, 121 (77.6%) had secondary education, and of the 155 educated partners, 104 (67.1%) had a high school level.

Of the 157 participants, 7 (4.5%) did not know any contraceptive method, 47 (29.1%) had never used one (this includes those having no knowledge of

contraceptive methods). All 110 (100%) who had knowledge of contraceptive methods knew of the existence of condoms, and the other methods were little known. Of the 110 (70.1%) who used a contraceptive method, 103 (93.6%) used condoms, with other methods being used very little (Table 2). Of all 157 participants, only 97 (61.8%) knew that they could be purchased at the shop and 80 (51%) at the pharmacy, 91 (58%) did not know of the existence of the services of FP, 149 (94.9%) were not attending FP services, 108 (68%) had had an unwanted pregnancy. The most common cause of non-use of contraceptive methods was partner refusal with a frequency of 38.3% (Table 2).

Among the 157 participants, all those aged 10 - 14 years and 68.4% of the age group 15 - 19 years had an unmet need for FP (Table 3). Also, 70.2% of those who had a secondary education and 70.5% of those who had had only one pregnancy had unmet needs. Knowledge of contraceptives or a source of contraceptives did not influence unmet needs. Seventy-point five percent of those who did not consult family planning services had unmet needs. Nevertheless, only unmarried and Christian religion seemed to increase unmet need in our study with respectively OR = 2.6 IC: 1.2 - 5.7 p = 0.016 and OR = 2.6 IC: 1.02 - 6.4 p = 0.040.

To find the factors independently associated with the non-satisfaction of FP needs, we used all the factors that were initially associated during the bivariate analysis (Table 4.) Only the unmarried status of adolescents independently increased the unmet FP needs: OR = 2.4 CI: 1.1 - 5.3 p = 0.035.

Teenagers made up 7% of births in our study, a frequency slightly lower than that of 9.3% found at the HCY in 2014 by Fouelifack et al. [8]. Their study concerned births from the HCY only and their sample size was larger than ours (5997 births).

Among the 157 participants (Table 1), 155 (98.7%) were between 15 and 19 years old, 135 (86%) were Christians and 124 (79%) were unmarried. The majority 156 (99.4%) were in school and 155 (98.7%) of their partners were educated. Up to 132 (84.1%) lived in urban areas. Sixty-two (39.4%) were from the Center Region and 44 (28%) from the West. One hundred and thirty-two (84.1%) had a gravidity of 1, and 136 (86.6%) had a parity of 1. Of the 156 school-going participants, 121 (77.6%) had secondary school level and of the 155 partners 104 (64.1%) had a secondary school education. We have not found another study to compare our results.

The rate of use of a contraceptive method (70.1%) (Table 2) is high compared to that of 11.9% obtained during the DHS V of 2018 [6] in Cameroon for the age group of 15 - 19 years [6]. Our data are hospital-based while those of the DHS are community-based. This could explain the difference. The condom use rate of 93.6% (103 out of 110) is close to 96% found in urban areas by Ajong et al. [9] in 2016. The condom remains the most well-known and used contraceptive method in urban areas in Cameroon. Moreover, this condom use rate is higher than the 5.6% rate of use among adolescent girls aged 15 to 19 found during the 2018 DHS V [6]. This can be explained by the same reasons mentioned above. The rate of 5.1% of adolescents who have already attended a FP center is much lower than the 28% found by Vilpert Sarah in 2008 [10]. His study was done in all “PROFAM” FP services in the world, while ours took place only in three hospitals in Yaoundé. Our rate of 68.8% who had had an unwanted pregnancy (Table 2), is higher than 45% found in 2017 in Africa by Darroch et al. [11]. This difference can be explained by the fact that we carried out our study in a hospital setting while theirs was done in a community setting.

In Table 3, unmarried status and Christian religion seemed to increase unmet need in our study with respectively OR = 2.6 CI: 1.2 - 5.7 p = 0.016 and OR = 2.6 CI: 1.02 - 6.4 p = 0.040. But after multivariate analysis (Table 4), only unmarried adolescents independently increased non-satisfaction of FP needs: aOR = 2.4 (CI: 1.1 - 5.3) p = 0.035. This factor had a significant link with unmet needs for FP as already found by Assefa et al. in Ethiopia [12] and Darroch et al. in New York [11]. The other studied variables had no association with unmet FP needs (Table 3 and Table 4), unlike other studies conducted in Cameroon [13] and Ethiopia [14] [15] which found significant associations. This difference can be explained by the difference between the types of study and the sample sizes.

According to Ajong et al. [16], despite the availability and sometimes free contraceptive methods at different levels in Cameroon, the frequency of use of contraceptive methods in the community is still low, while the unmet need for FP which is one of the main monitoring indicators for FP programs are supposed to be kept as low as possible or even zero if the third objective of sustainable development is to be achieved. The social recognition of young women’s sexuality exerts a decisive influence on their perception of the “risk” of pregnancy, on their access to information and contraception and their contraceptive practice [17]. Thus, in countries such as France where adolescents’ access to contraception is most widely authorized by law, young people protect themselves more against unplanned pregnancies [18].

Limits of the study

We used a cross-sectional study design, which can only pick up associations rather than causal relationships. During the period of our study, we were confronted to the pandemic due to Corona Virus 19. The official prescription of confinement has largely contributed to the drop in the hospital attendance rate. During recruitment, some teenage girls were ashamed to answer certain questions and could therefore give us incorrect answers. This behavior was more accentuated by certain religious or socio-cultural beliefs.

Among the 157 participants, 132 (84%) had had at least one pregnancy, 136 (86.6%) had given birth at least once. The frequency of non-use of contraceptive methods among adolescents was 29.9%. We noted a low attendance rate for FP services (5.1%), a high rate of unwanted pregnancies (68.8%). The best-known source of contraceptive method supply was the shop (61.8%). Partner refusal was the most cited reason for not using contraceptive methods (38.3%). Being unmarried was independently associated with the occurrence of unmet needs. We suggest that FP actors favor the community approach to health, targeted at adolescents. The intensification of behavior change communication campaigns and the creation of services dedicated to the sexual and reproductive health of adolescents would make it possible to reduce the rate of unmet needs for FP among adolescent girls.

The authors heartily appreciate the administrations of the three hospitals, for having eased in carrying out of this study as well as their teams working at the Obstetrics and Gynecology Units for their support during data collection. We also thank the participants for providing us with the information during data collection.
