Abstract

Background: Adolescent pregnancies are characterized by high rate of maternal, foetal and neonatal morbi-mortality. Adherence to antenatal care still remains a major challenge amongst pregnant adolescents in a resource-limited setting.

Objective: The aim of this study was to determine the rate of loss to follow up of adolescent pregnancies and describe the determinants of this loss to follow up.

Methods: We conducted a 1: 1.3 unmatched case-control study at adolescent clinic of the Yaounde Gynaeco-Obstetrics and Paediatric Hospital, Cameroun from November 2016 to June 2017. Cases were pregnant adolescents aged between 14 to 19 years loss to follow-up during antenatal care, meanwhile those who completed their pregnancy follow-up constituted the controls. An error margin of 5% was set. A multivariate analysis was performed to rule out confounders.

Results: A total of 549 adolescents consulted for antenatal care in the adolescent clinic. Overall, 308 (56.1%) of them completed their follow-up till delivery given a rate of loss to follow up of 44%. After multivariate analysis independent risk factors associated with loss to follow-up were working in the informal sector, originating from the North-West region of Cameroon, the long waiting period during antenatal consultation, long distance to the hospital, medical fees (antenatal consultations and laboratory) considered as expensive, high cost of delivery, the aggressive attitude of the hospital staff, large family size and low socioeconomic status.

Conclusion: About half of all adolescents’ pregnancies in Yaoundé have a loss to follow up. This high rate of loss to follow up is due to multiple sociodemographic, cultural, medical, logistics and obstetric determinants. The identification of these factors could help decision makers in improving adolescent access to quality medical care during pregnancy.

Introduction

Adolescent pregnancy is a public health problem. Globally, it’s constitute about 49 deliveries per 1000 deliveries making 11% of all deliveries [1]. The huge majority of these deliveries occur in the low-and middle-income countries and particularly in Sub-Saharan Africa where more than half of the female population deliver before the age of 20 [1,2]. In Cameroon, Tebeu et al. find out that adolescent deliveries make up about 14.2% of all deliveries [3].

Pregnancy in adolescents should attract a particular attention due to increase morbidity mortality for the mother and the future baby. These complications may include: hypertensive disorders, anemia, dystocia, preterm delivery, as well as maternal and child deaths [2]. Maternal death is doubled in adolescents when compared with women aged 20 to 24 years, making it the second leading cause of death in girls aged 15 to 19 years [1]. Babies born of these adolescents are more exposed to risk of morbidity and mortality when compared to those of older women, and it is most often related to prematurity and small for gestational age birth weights. One of the principal determinants in this age group is the low access to health care, school dropout and low social status [2,4].

In an effort to resolve this problem in the Yaounde Gynaeco-Obstetric and Pediatric Hospital (HGOPY) in Cameroon, the administration of the hospital created an Adolescent Clinic with the objective of taking care of their health concerns through mass education, health campaigns, open-door activities and free clinical consultation. This study was carried out in the Adolescent Clinic of HGOPY. The objective was to describe the general characteristics of adolescents followed up with pregnancy in this clinic, determine the rate of loss to follow up and describe the sociodemographic, medical, and obstetric determinants of these loss to follow up adolescents pregnancies. Our preliminary literature search did not find a similar study done before in Cameroon. A few incomplete studies were found in the African literature, which grouped the factors into individual factors, family and obstetrical factors [4-7].

Materials and Methods

Study design and setting

An unmatched case-control study was carried out in the adolescent clinic of HGOPY to determine the factors associated with loss to follow-up during antenatal care in adolescent pregnancies for seven months, from November 2016 to June 2017. The group of cases was the loss to follow-up, meanwhile those who completed their pregnancy follow-up constituted the control group. The Schlesselman’s formula was used to calculate the minimum sample size required, estimated at 210 participants at a ratio of 1: 1.3 cases and controls respectively. Ethical clearance was obtained from the Institutional Review Board of the Faculty of Medicine and Biomedical Sciences of the University of Yaounde I, and also from the Institutional Ethics Committee of HGOPY. Each participant’s written consent was obtained before the interview was conducted.

Study participants and procedure

A total of 97 cases were compared with 127 controls, making a case-control ration of 1:1.3. The study population was made up of teenagers aged between 12 and 19 years, contacted through phone calls, their phone numbers were retrieved from the medical records. The procedure consisted in booking home visits with all those who were reachable by telephone. An interview was then conducted and data collected on a pretested questionnaire. For those who were reachable by telephone but who were out of town, their interviews were done through phone calls. Adolescents whose parents or guardians did not consent to participate where excluded from the study

Data analysis and management

Data was entered and analyzed using the Epi info 3.5.4 software. Tables were obtained with the help of Excel and Word 2013 software. The Chi square and Fischer’s exact tests were used to compare variables. An error margin of 5% was set. The Odds ratio with 95% confidence interval was used to determine statistically significant risk factors. A multivariate analysis was done to check for confounders.

Result

General characteristics of the study population

We recorded a total of 524 pregnant adolescents who had started antenatal consultation at HGOPY. Two hundred and forty three were eligible, and among them, 19 did not give their consent. Hence, we enrolled 224 participants of whom 97 were cases of loss to follow-up and 127 were those who completed their antenatal visits and delivered in HGOPY (the control group). The 17-19 years age group was the most represented (86.6%) with an average of 18±1.2 years. Students constituted the majority, 59.1%. Adolescents originating from the West region of the country were the most represented (38.1%) followed by those from the Centre region (35.1%). The risk of loss to follow-up was multiplied by 13 for adolescents from the North West Region (OR=12.89, P<0.001). Catholic Christians made up 57.7% of the study population. Secondary education was the most represented level of education (83.5%), followed by higher education (13.4%) and then primary education (3.1%). Most of the adolescents lived within a radius of 5 kilometres from the hospital (50.5%). Only 3.1% lived at 15km and beyond from the hospital. However, the average geographical distance was 6.9±16.6 km. Spinsters represented 57.7% in the two groups, followed by 21.6% who were co-habiting and only 20.6% were married. Table 1 summarises the sociodemographic characteristics of the study population.

Determinants of loss of follow-up during adolescent pregnancies

The majority (91.8%) of adolescents perceived pregnancy as an important state that needed medical attention. The long wait during antenatal consultation as observed by 71.1% of the adolescents, multiplied by 5.77 times the risk of loss to followup (P<0.001). Those who considered their residence as far from the hospital, were at 9.4 times risk of interrupting antenatal visits (P<0.001). Medical cost of follow-up when considered to be expensive, multiplied by 8.8 times the risk of interrupting discontinuing antenatal visits (P<0.001). Those who saw delivery fees to be expensive had a 16.2 times risk of not ending up her pregnancy in HGOPY (P<0.001). The risk of discontinuing care was multiplied by 10.6 times when the health personnel presented an aggressive attitude (P<0.001). More than half of the adolescents (58.8%) started antenatal consultations in the second trimester (Table 2). In 16.5% of the cases, the fear of disclosing the pregnancy to the family caused the delay. In 15.5% of the cases, the visits were started in a health centre before transferring to HGOPY. A good proportion (46.6%) did all their consultations in HGOPY but delivered in a different centre. After the first consultation, 20.6% discontinued consultations in HGOPY, meanwhile 14.4% stopped after the second consultation. Adolescents from large family sizes represented 30.9% and in 70.1% of them, their families were poor, with a 2.38 risk of discontinuing care (P<0.001). The average monthly family revenue was 35133.9 FCFA. In 81.4% of the cases, the head of the family was a male and in 61.9% of cases, the family head’s level of education was secondary and 55.7% of them worked in the informal sector. In 78.4% of the cases, the medical fees were paid by the head of the family and this increased by 5.76 times the risk of discontinuing medical consultations in HGOPY (Table 3). Sociocultural considerations affected follow-up in 7.2% of adolescents, due to the fact that a first baby born in the home of the man in 57.1% of cases and in the home of the woman in 42.9% of the cases.

After logistic regression, statistically significant risk factors for loss to follow-up were: origin from the North West Region, working in the informal sector, the aggressive attitude of the health personnel, delivery fees considered as expensive, belonging to a large family size and when the medical fees were paid solely by the head of the family (Table 4-6).

Discussion

The aim of this research work was to identify the risk factors associated with loss to follow-up of adolescent pregnancies at the Yaounde Gynaeco-Obstetric and Paediatric Hospital. It was noticed that their socio-demographic characteristics, individual factors, family factors and cultural factors influenced the discontinuity of care in this hospital. The weak economic power, especially of those adolescents working in the informal sector like subsistent farming had an impact on the continuity of care in HGOPY. Rwenge JR and Tchamgoue HB had a similar finding in Cameroon in 2004 [4].

The region of origin of the adolescent was a significant factor associated with this loss to follow-up for teenagers originating from the North West region. This risk was multiplied by 13, similar to that obtained by Rwenge JR et al. [4]. This could be explained by the culture of this region, wherein it is habitual that a woman’s first delivery should take place either in the environment of her parents or in that of the husband’s parents. Hence, teenage primarous descendants of the North West region may have travelled back to their home towns to deliver leading to loss of follow up in the study setting.

The geographical distance from their residence to the hospital was a big limiting factor. Those who considered the distance as far, had a 9.42 risk of interrupting follow-up at HGOPY. Tollegbe A in 2004 in Bénin and Kamga G-R in 2010 in the North of Cameroon found these risks multiplied respectively by 5 and 4 [5-7]. This difference could be explained by the fact that in their series, adolescents from rural areas residing at more than 15 kilometres from the hospitals were those greatly affected. In our series, this aspect concerned both those living in and out of the town of Yaounde. Our adolescents had a more subjective perception of this notion of far distance, which in some cases the distance was not really far.

The cost of care of pregnancy and delivery fees considered as expensive were significant factors associated with loss to followup. This finding correlates with the declaration by the French Red Cross in Mali in 2013 stating that financial accessibility is the main barrier to health care in health facilities. The bulk of this high cost was mostly the paraclinical investigations in the first visit that ranged from a hundred to a hundred and twenty thousand francs. The required delivery caution fees of 50,000 FCFA was considered expensive and not easy to gather and deposit in a single instalment.

The aggressive attitude of the hospital staff at the reception, Radiology service, and at the outpatient consultation boxes of gynaecology increased the risk of discontinuing follow-up by 7.4 times. A Prual in 1999 got a similar result in West Africa [8]. The aggressiveness mostly was because the nurses were judgemental on them getting pregnant at a tender age and their impolite language. This attitude however goes against the WHO 1998 declaration on the impartial nature of care to women seeking the services of reproductive health.

The long waiting time at the reception to get a medical file (30 minutes) and infront of the consultation boxes (4 hours), multiplied the risk of discontinuing follow-up by 5.77 times. Some of these adolescents would return without being consulted. Most of the adolescents being students (59.8%), were therefore greatly affected because they had to miss classes on such days in order to be consulted. The phenomenon was further aggravated by the fact that some of these adolescents arrived the hospital as early as 6:00 am in order to be consulted early, so as to arrive in school early for classes. That was unfortunately very often not the case.

Some of the difficulties encountered by these adolescents were the delay in rendering results of diagnostic tests. Some had their results even missing, and also the inability of being consulted if the medical file could not be retrieved from the archival service. Adolescents from large family sizes were more at risk of discontinuing care. The risk was multiplied by 5.87 times. This result was similar with that of Rwenge JR and Tchamgoue HB in Cameroon in 2004 [4]. This could be explained by the fact that large family sizes have a much weaker economic power and as such the financial access for medical care cannot easily be guaranteed [9].

The living standards of their families also significantly affected their adherence to follow-up in this hospital. Those from poor families were 2.38 times at risk of discontinuing care. This finding was similar to that of Rwenge JR and Tchamgoue HB in Cameroon in 2004 [4]. This was simply due to the fact that 69.1% of these adolescents came from families with low standard of living and this impacts their health care because health financing in Cameroon is mostly taken care of by direct payment from the family financial basket if at all there exists one [5].

Whenever the medical fees of the pregnancy was paid by her family head, the risk of discontinuing care was multiplied by 5.76. This could be explained simply by the large family sizes and their weak economic power. Cultural barriers were significant in interrupting follow-up at HGOPY. This was particularly true for those adolescents from the West, North and Extreme North Regions where their first deliveries must take place in the homes of either the adolescent’s parents or in the home of the partner’s parents. Tollegbe A in Benin in 2004 obtained a similar result [5].

Conclusion

The rate of loss to follow up for antenatal visits in adolescents is high. Multiple cultural, sociodemographic, logistics and medical factors contribute to increase this significantly. Improving the attitude of the hospital staff at reception, reducing the waiting time and the cost of pregnancy care and delivery fees for adolescents would significantly reduce the rate of loss to follow-up and as such, improve upon the reproductive health of the adolescent population.
