1. Introduction
With a fertility rate of 128 births per 1000 women between the ages of 15 and 19, Bangladesh has the highest adolescent fertility rate in the Asia Pacific [
1]. Despite the legal age of marriage being 18 years old for girls, 59% of adolescent girls are married at a younger age [
2]. Once married, the girls are often pressured by family members to prove their fertility, which results in early, undesired pregnancies [
3].
Adolescent pregnancy is correlated with pregnancy-related complications, preterm delivery, low-birth weight babies, and spousal violence [
4]. A higher proportion (19%) of unintended pregnancies (UP) result in abortion when conceived within one year of marriage [
5]. The broader social consequences for these girls include lower educational attainment, limited ability to partake in income-generating activities, higher overall fertility rates, and marital and familial difficulties [
4].
Evidence shows that married adolescent girls (MAGs) in urban slums are almost twice as likely to be mothers as their counterparts from non-slum areas [
5]. Greater than 50% of the pregnancies in slums are unintended, which is more than two-fold greater than the number of unintended pregnancies in MAGs in all urban (22%) and rural (24%) areas of the country [
5,
6]. These trends align with the finding that the proportion of MAGs in slums with an unmet need for FP was higher (15%) when compared with their counterparts in non-slum urban areas of Bangladesh (10%) [
7]. Unintended pregnancies among MAGs in urban slums are largely attributable to the lack of accessible family planning (FP) and reproductive health (RH) services, and non-use or discontinuation of modern contraceptive methods [
6,
8]. The latter is caused by user-related factors, which includes a lack of awareness of available methods, inconsistent use of methods, fear of side effects, method failure, external pressure from husbands and in-laws to have children, and a lack of spousal communication [
6,
8]. Findings show that 15% of the MAGs in slums have never used any modern contraceptive method, while 27% have discontinued their chosen method [
5].
Although research has been done on contraceptive method use and the unmet need for FP among women of reproductive age in Bangladesh, there are limited data on the specific issues among MAGs in urban slums. More specifically, there are few studies on targeted interventions for this population. Evidence shows that providing comprehensive information on FP through peers and providing innovative behavior change communication (BCC) materials can be effective tools for women in low- and middle-income countries (LMIC) for delivering customized information on and addressing cultural and social barriers to adopting FP services [
9].
This study assessed the effectiveness of married adolescent girls’ clubs (MAG clubs) in providing comprehensive information on FP through examining the attitudes, knowledge, and practices of MAGs in urban slums of Dhaka. The expected outcome of this study was to find a difference in the utilization of FP services and methods between the study participants in the control and intervention areas.
2. Materials and Methods
2.1. Study Setting
The study was implemented in four urban slums of northern and southern parts of Dhaka City Corporation, Bangladesh. These slums were selected because they had definite geopolitical boundaries and were at a distance from each other, preventing the overlap of slum populations and consequent interactions which might bias the evaluation of the intervention. Two of the slums (Mirpur and Kamrangirchar) were randomly assigned to the intervention group and the other two (Shekhertek and Rayerbazar) to the control group. The assignment of the slums between the groups was completed independently by a statistician based on a computer-generated random sequence. It was anticipated that the random assignment of slums would ensure exchangeability between the control and intervention groups.
2.2. Study Design
This was a quasi-experimental study with a post-test only design conducted between July 2014 and August 2016, with a 12-month implementation phase lasting from March 2015 to February 2016. Logistical constraints prevented baseline data collection, leading to the post-test only design. To assess the effectiveness of the intervention, a quantitative survey was administered in both the intervention and control areas after the program was completed. Participation in the intervention was open, which meant that study participants were able to join and leave throughout the intervention period.
2.3. Study Population
The study population was married adolescent girls (MAGs) between 14 and 19 years’ old who resided in the selected four slums. Both pregnant and non-pregnant MAGs who had lived with their husbands and/or families in the selected slums for at least six months and were willing to participate in the study by providing written consent were included in the intervention. MAGs who were divorced, separated from their spouses, or had speech or hearing disabilities were excluded from the study.
2.4. The Intervention
The Government of Bangladesh and local non-governmental organizations (NGOs) run several adolescent clubs in both rural and urban areas of the country. The clubs provide adolescent girls and boys with an opportunity to gather and discuss issues that matter to them, such as birth registration, early marriage, dowry, human rights, sexual and reproductive health (SRH) related issues, including the transmission of STIs, and substance use/drug abuse. The majority of these pre-existing clubs target unmarried adolescent boys and girls, failing to reach adolescent girls who are married. Girls married at an early age may lack access to appropriate SRH information provided by these clubs. To fill this gap, icddr,b, a Bangladesh-based international health research institute that strives to solve key public health problems through high-quality scientific research and innovation, initiated this project through collaboration with brac, an international NGO. brac has been delivering basic maternal, neonatal, and child health (MNCH) and family planning services through a community-based health intervention under its Essential Health Care (EHC) Program, in selected urban slums of several city corporations and selected municipalities, including Dhaka in Bangladesh. Since 2007, this community-based health program, known as Manoshi, has been working to reduce maternal and child mortality in urban slums of Bangladesh by providing normal safe delivery services through its birthing huts at the community level. Family planning (FP) is one of the integrated components of the Manoshi programme and brac has been implementing a few approaches among the eligible couples, women, family members, and community groups to promote FP in addition to maternal, neonatal, and child health care.
Brac has significant experience in running clubs for married and/or unmarried adolescent boys and/or girls in Bangladesh. In this study, brac’s club model was replicated to target married adolescent girls in urban slums. Facilitators to conduct the club sessions were recruited from current brac club leaders as well as brac school teachers. They were trained on matters relevant to SRH, early marriage, unintended pregnancy, and family planning. A total of 10 facilitators were recruited. A team of experts in adolescent and maternal health from icddr,b and brac worked closely to finalize club locations, infrastructure, topics for club sessions, training manuals, and guidelines.
Each month of the intervention had a unique club session curriculum. The 10 facilitators held sessions at their assigned brac school using the pre-established monthly curriculum once every week. There was a total of 40 sessions covering the same material every month. The frequency of sessions allowed for MAGs to have flexibility in selecting a session to attend each month without missing information. Each MAG could attend up to 12 unique club sessions during the one-year intervention period; an average of 20 MAGs participated in each session. A total of 1709 different girls participated in these clubs throughout the intervention period.
Every three months, club participants completed an assessment on the topics discussed during sessions and were awarded token prizes based on their performance for further motivation to remain actively engaged.
Beyond discussion, recreational activities such as dance, music, and drama were arranged for club members. Participants produced and performed plays based on members’ life stories during the final club session. In addition to participating in organized educational and recreational activities, each club attendee received a small pocketbook with information on SRH, early marriage, and family planning in Bengali. This miniature book was designed to be attractive to and practical for teenagers. Each cover was adorned with a mirror and decorative jewels and every book was attached to a key chain.
2.5. Sampling Procedure and Sample Size
The survey participants were selected from both the intervention and control areas using a cluster sampling procedure. One kilometer radius from the central point of the slums was denoted as a cluster, and each selected slum was divided into numbers of concentric clusters. A total of 20 clusters were generated for the intervention areas and 15 clusters were generated for the control areas. Then, 10 clusters from each intervention and control areas were selected as study sites through simple random sampling using a computer-generated random sequence. A computer programmer, with no additional involvement in the study, completed the randomization process to prevent bias.
Approximately 6000 households from the 10 clusters of the intervention areas were approached and around 3528 MAGs identified through these household visits were invited to participate in the clubs. Ultimately, 1709 of the MAGs enrolled in the club sessions. Of these participants, 800 were randomly selected for participation in the survey. In the control areas, a random direction was selected from a central location of the slum to determine the first household invited to participate in the quantitative survey. All households in the direction selected were visited and each eligible respondent was invited to take part in the survey. This process was continued until the required sample size was achieved.
In total, 1601 MAGs were included in the survey; 799 from the intervention areas and 802 from the control areas. Each survey was administered through individual face-to-face interviews in both the intervention and control areas. Written consent was gathered from participants before interviews were conducted.
2.6. Statistical Analysis
Data were entered into a computer database using Oracle 11G.R2 (Oracle Corporation, Redwood Shores, CA, USA) and exported to STATA 13.1 (Stata, College Station, TX, USA) for analysis. Descriptive statistics, Pearson’s Chi-Square tests, two-sample independent t-tests, two-sample proportion test, and Fisher’s exact test were used for quantitative data analysis. Differences in participant characteristics, as well as key outcome indicators between the intervention and control areas, were analyzed for statistical significance at an alpha level of 0.05.
As there were statistically significant differences between study participants from intervention and control areas in socio-economic factors as well as reproductive history, multivariate regression models were developed to control for these differences. However, to investigate the effect of the MAG club in the intervention areas compared with control areas, the logistic regression models were analyzed. Crude and adjusted odds ratios were calculated through separate logistic regression models for each of the following key outcomes: (i) knowledge of modern FP methods; (ii) currently using a modern method of FP; (iii) respondent supports using FP methods; (iv) husband supports using FP methods; (v) responsibility of FP is shared between husbands and wives; (vi) identifies consequences of early pregnancy correctly; and (vii) discussed FP methods with husband. A cluster’s effect was also adjusted during the running of the models. Logistic regression analyses were used to determine if differences in estimating variables in the intervention areas compared with the control areas were statistically significant when adjusted for independent variables. The analyses for these outcomes were all controlled for the educational attainment of both respondents and their husbands, employment status of the respondents, age of marriage, mean duration of marriage in years, and number of pregnancies that the participant has experienced (including current pregnancy). To identify other potential sources of bias, each background characteristic, even those that were not significantly different between intervention and control areas, were logistically regressed with each outcome variable. Additional covariates for each outcome’s regression model were added in a stepwise fashion after controlling for differences in intervention and comparison areas.
2.7. Ethical Clearance
The study obtained ethical approval from the institutional review board (IRB) of icddr,b (International Centre for Diarrhoeal Disease Research, Bangladesh) and the Population Council, New York. The Population Council funded this study.
4. Discussion
This quasi-experimental study was designed to assess the effectiveness of an innovative intervention, the married adolescent girls’ club (MAG club), to see whether there were differences in the knowledge of, attitude towards, and utilization of contraceptive method practices among two groups (intervention and control) of married adolescent girls in urban slums of Dhaka, Bangladesh.
It was revealed that a noteworthy number of married adolescent girls had received extensive information on family planning from the MAG clubs. More respondents in the control areas than the intervention areas were pregnant at the time of evaluation, suggesting that the MAG club may have had a positive influence in reducing the number of pregnancies.
Findings from this study showed that other than the oral pill, there were significant differences in the knowledge of different contraceptive methods and of potential problems associated with adolescent pregnancy between the groups. Respondents in the intervention areas with no children expressed their intention to delay their first pregnancy by at least three to five years, an observation not found in the control areas. The current study also revealed a significant difference in attitudes towards contraceptive method use among respondents of the two groups; more respondents and their husbands in the control areas did not support any FP method use than their counterparts in the intervention areas. Furthermore, a larger percentage of respondents and husbands in the intervention areas indicated that family planning was a shared responsibility. After controlling for respondents’ characteristics that were different between control and intervention areas, the adjusted odds of believing FP is a shared responsibility were still higher in the intervention areas than the control areas. This suggests an association between the intervention and the outcome that was still present after controlling for potential sources of bias.
Findings from another study revealed husbands’ opposition to contraception as a barrier to the use of FP methods, even if women had the knowledge, access, and intention to use contraceptives [
10]. However, the current study identified that respondents in the intervention areas discussed FP methods with their husbands, which could be the effect of an element of the sessions that taught women how to engage their husbands in family planning discussions and decision making. Findings also showed comparatively greater use of male methods (condoms) in the intervention areas, which is suggestive of one of several key elements of empowerment and gender norm change found in other studies [
11].
The current use of any modern contraceptive methods and its adjusted odds were higher and the unmet need of family planning was lower among respondents in the intervention areas than in the control areas. This finding is in alignment with research utilizing data from BDHS 2004, which found that having an unmet need was significantly lower (
p < 0.001) when there was spousal communication about contraceptive methods [
12]. Long-acting reversible contraceptive (LARC) methods uptake in the intervention areas was higher than that of the control areas, suggesting that there may be an association between club participation and receptiveness towards this method. A similar finding was observed in a study in Malawi on peer leaders trained to deliver youth-friendly FP services [
13].
4.1. Strengths of the Study
Although several programs to improve the SRH of adolescents are being implemented in Bangladesh, the efficacy of these interventions is rarely documented. Furthermore, there is a lack of programs focused exclusively on married adolescent girls in urban slums. This is the first study to document the effectiveness of MAG clubs in generating knowledge on, changing the attitude towards, and encouraging practices of family planning among married adolescent girls in urban slums. Additionally, the presence of a control group in this quasi-experimental design acted as a proxy for the counterfactual and partially mitigates history and maturation threats. As the same survey was used for all participants, testing and instrumentation threats were controlled.
4.2. Limitations of the Study
Although a quasi-experimental study, the post-test only design limits the conclusions that can be drawn from the data. As there was no pre-test data, the differences observed between intervention and control groups cannot be attributed solely to the program. Furthermore, there were differences between the intervention groups and the control groups, such as employment, that may have affected internal validity; however, the logistic regressions revealed significant results even after controlling for these factors. There were still factors that could not be controlled. For example, as participants in the intervention areas chose to join MAG clubs and assignment to the intervention was not randomized, selection bias may have threatened internal validity. Recall bias may have resulted from the use of self-reported data. There may be confounding factors which were not accounted for and causal inferences cannot be made. As participants were not involved in the design of the FP pocketbook, the acceptability and utility of this element of the intervention among participants is not certain. Furthermore, findings of this study may not be generalized to married adolescent girls living in rural areas of Bangladesh, as the adolescents living in those areas have different profiles and living conditions.
5. Conclusions
Adolescent pregnancy is a major social and health concern in Bangladesh. An appropriate intervention for married adolescent girls must be implemented to increase access to correct and comprehensive information on FP methods and services. Early marriage is a central component to the physical, social, and economic risks of early pregnancy, and girls from urban slums are especially vulnerable. Along with FP, the deleterious effects of early marriage, early pregnancy, and motherhood are important messages that need to be conveyed to this group of young women [
14]. The findings of this intervention suggest that the married adolescent girls’ club (MAG Club) was an effective and well-received strategy to generate knowledge on and encourage the use of contraceptive methods. MAG clubs have the potential to effectively improve married adolescents’ sexual and reproductive health (SRH) in urban slums in Bangladesh.
The current Strategic Plan for Health, Population, and Nutrition Sector Development Programme (HPNSDP) [
15] encourages the adoption of long-acting and permanent methods (LAPM) of contraception, as these methods are used minimally throughout the country. In addition, the Government of Bangladesh has placed an emphasis on improving the health of adolescents through developing the National Adolescent Health Strategy [
14]. To meet the targets in this strategy, the government could leverage its existing resources and workforce in urban areas, specifically in the slums, to replicate the club model and engage with this age group more efficiently. Capacity building of the community health workers, through collaboration between the government and the NGOs, could further improve family planning service provision and uptake. This would allow for the government to not only focus on adolescents but encourage their use of methods in alignment with strategic policy.
Further research is required to ascertain whether statistically significant differences between the intervention and control areas are attributable to MAG clubs. Additionally, this intervention should be studied in rural settings of Bangladesh to assess its feasibility and which adaptations are necessary for replication and scale-up nationally. This can be accomplished by utilizing the government’s existing infrastructure and resources allocated to prevent adolescent motherhood.
