Preferences and Motivations of Women Who Use Traditional Contraceptive Methods to Avoid Pregnancy in Sub-Saharan Africa: A Systematic Review

Introduction: When it comes to family planning, requirements and preferences vary among couples. Because of their mixed effectiveness, traditional contraceptive methods are often associated and accounted as unmet needs. However, interest in these methods is growing significantly. Nevertheless, knowledge of the reasons for the decision and using traditional contraceptive methods remains limited. The purpose of this study was to identify the preferences and motivations of women who use traditional contraceptive methods to avoid pregnancy in Sub-Saharan Africa. Method: A literature search was conducted in three electronic databases (PubMed/Biomed Central/Medline, Embase, CINAHL). Two independent individuals selected the eligible quantitative, qualitative, and mixed studies published between 2011 and 2020. We conducted a narrative synthesis to organize and group preferences and motivations that facilitate traditional contraceptive methods use. Results: Abstinence, withdrawal, breastfeeding, rhythm method were the main preferences to contraceptive planning methods identified. Factors influencing the use of traditional contraceptive methods were the lack of knowledge, the side


Study Selection
The study selection step was carried out independently by NB, YP and PN.The titles of the studies were screened after the removal of all duplicates.A total of records (n = 748) were initially screened.Eligible studies ought to include the following criteria: 1) been a research study; 2) been written in English or French; 3) report based on the female; 4) using quantitative, qualitative or mixed-method; 5) been on the period January 2011 to December 2020; and 6) limited to sub-Saharan Africa.A list of relevant articles was also reviewed for additional publications.The list of records was prepared, and then the full texts were reviewed independently by the three authors (NB, YP and PN).The different disagreements linked to inclusion were treated through discussion involving all investigators (Figure 1).

Data Extraction
The authors independently extracted data from each study that fulfilled the criteria.The forms ensured data extraction was as consistent across all studies, as the extracted data were used to synthesize the findings.For each study, the following characteristics were extracted: 1) name of the first author, 2) year of publication, 3) country where the study was conducted, 4) setting where the study was conducted, 5) study design, 6) participant's characteristics, 7) the main outcomes.This review has focused on the preferences and motivations for using traditional planning methods by women in sub-Saharan Africa through qualitative, quantitative or mixed methods.So, only information came from participants and reported preferences or motivations were extracted.

Quality Assessment
We used the mixed methods appraisal tool (MMAT) [16] to appraise the methodological quality of the studies included in the systematic review, five (5) Figure 1.PRISMA flowchart.The selection process for the systematic review on preferences and motivations for using traditional planning methods.questions for each method (qualitative, quantitative or mixed-method).The MMAT was developed to provide a quality appraisal of quantitative, qualitative and mixed-method studies.Then, selected studies were assessed for methodological quality.

Data Synthesis
For this step, we used a technique based on a narrative approach.First, a systematic narrative synthesis was conducted by using the information as reported in the study's characteristics.Then, narrative synthesis, according to Petticrew and Roberts [17], was used.This technique recommends three steps: 1) Organization of studies in logical categories.In this systematic review, studies were gathered depending on whether they deal with preferences and motivations.2) Analysis of each study.We conducted a narrative description of each study and a description of the quality of the study by Petticrew and Roberts [17].3) A general summary of the results of the studies was established.We used the Socio-Ecological Model (SEM) secondly to group the women's motivations for using traditional planning methods.The SEM is a framework that examines multiple effects and interrelatedness of environmental, contextual, and social factors on individual behavior [18].Because many challenges in public health are too complex to be well understood and addressed from single-level analyses, the SEM helps to a best comprehensive approach by including many levels of influence to impact health outcomes and health behaviour.

Study Selection
The primary search strategy identified 748 potentially relevant citations.After removing duplicates and the initial title and abstracts screening, 68 studies were kept for the full-text review.Studies were excluded if they were not Sub Saharan Africa studies, not limited to January 2011 to December 2020, not focused on females.The remaining 13 studies were appraised for their methodological quality and included in the analysis.No study was excluded based on quality assessment.A flow chart illustrating the selection process is shown in (Figure 1).

Study Characteristics
A total of 13 eligible studies were included in the review.Of these 13 studies, one was from Botswana, one from Congo, two from Nigeria, two were multicenter, three were from Ghana, one from Burkina Faso, one from Ethiopia and two from Uganda.In addition, three of them used a mixed-method while the other ten used a quantitative method.Table 1 provides a brief overview of the key characteristics of the included studies.

Quality Appraisal Results
In general, studies were of high quality (Table 2).A total of nine studies scored 5/5, three studies scored 4/5, and one study scored 3/5.

Preferences to Using Traditional Family Planning Methods
The thirteen (13) studies included in this review identified a total of five (5) traditional planning methods used by women in sub-Saharan Africa.The main methods were abstinence, withdrawal, breastfeeding, rhythm method and herbal medicines.
This systematic review revealed that one of the traditional contraceptive methods was abstinence.It was relayed by six authors [19]- [24].Some of these studies showed that the prevalence of these methods was 55% [19], at 16.3% [21], and 4% [23].Five of the studies included in the review reported that withdrawal was one of the traditional methods of contraceptive practice among women in sub-Saharan Africa [21] [23] [24] [25] [26].This method was used by 14.1% of study participants [24], 32% [21] and 2.7% according to Bekele & Fantahun [25].
Three authors [25] [27] [28] reported that the Rhythm method was used at different rates.For example, this method was 2.7% [25] and 72% [27].With one's spouse, the desire to space children was predictive of clients' intention to adopt family planning in the future; the rhythm method was the most patronized [28].

A total of 184 SDM users were interviewed
The mean and median ages were 29.47 (SD ± 6.05 years) and 30 years, respectively.The majority of the study subjects were Orthodox Christians (76.6%), married (93.5%), attended primary school (52.2%), housewife by occupation (40.8%), and had children (96.2%), with a mean of 3.2 children per woman.On average the study subjects had used the SDM for 13.8 months.Seventy-seven women (42%) had practised the SDM for more than 1 year, while 64 (35%) had used the method for between 6 months and 1 year.
The most common reasons for choosing the SDM were the absence of health effects/side effects, in 129 (70.1%) cases, followed by fear of side effects, particularly of hormonal contraceptives (n = 99, 53.8%), and ease of use (n = 9, 4.9%).Additional reasons were that it is available without cost to the individual (n = 5, 2.7%) and because it is a natural method (n = 5, 2.7%).Barriers: Ten had to stop using the method because they had two menstrual cycles that fell outside the 26 -32-day range within a year.Seven women lactational amenorrhea method (n = 5, 2.7%), rhythm method (n = 5, 2

409,399 women
Use of traditional methods is higher among women who wish to limit/end childbearing and among better-educated, urban, and wealthier women, but only slightly higher for ever-married women compared to never-married ones.A higher proportion of older women now use traditional methods, as do never-married women compared to ever-married women.The proportion of traditional method users among those with a demand for contraception is six times greater among women with a secondary education compared to those with no education 4

Motivations for Using Traditional Family Planning Methods
The different factors motivating women to use traditional contraceptive methods have been grouped according to the different levels of the socio-ecological model: individual, interpersonal and organizational levels.

Individual-Level 1) Socio-demographic characteristics
In this review, several socio-demographic characteristics contributed to explaining women's choice to use traditional contraceptive methods.

 Education
Six studies have relegated the level of education as a factor in the choice of contraceptive methods [20] [21] [23] [24] [28] [29].According to Atiglo [20] and Wuni [28], senior high school education was significantly associated with the likelihood of current abstinence.According to Straveteig [29], women who preferred traditional methods were often urban and educated.As for Rossier & Corker [23], the use of traditional methods is higher among better-educated. Age Age has been found in two studies [23] [30] as a motivating factor in traditional contraceptives methods.Employment was significantly associated with traditional methods for women who were older than 30 years [30].At the same time, Rossier & Corker [23] found that a higher proportion of older women now use traditional methods.

 Socioeconomic factors
Three studies [20] [23] [30] reported that traditional contraceptive methods were found among the richest women.The use of traditional methods is higher among wealthier women [23] [30] and rich categories [20].

 Residential environment
The residential environment was found as a factor of choice in traditional contraceptives methods.Three studies included in this review [23] [29] [30] identified that women who choose traditional methods live in urban areas.In addition, the use of traditional methods is higher among women who wish to limit/end childbearing and among better-educated, urban [23], who lived less than 30 km from a major town [30] and were often urban [29].

2) Cognitive factors
In this review, some authors [24] [25] [27] identified fear related to the side effects of modern contraceptive methods as a factor in the choice of traditional contraception.For example, the most common reasons for choosing the SDM were the absence of health effects/side effects, in 129 (70.1%) cases, followed by fear of side effects, particularly of hormonal contraceptives (n = 99, 53.8%), and ease of use (n = 9, 4.9%) [24] [25].As for Mathe [27], traditional methods were more often used than modern methods (in 64% of cases in the past and 65% before the last pregnancy), and the main reasons were the lack of knowledge and fear of side effects.Finally, one of the studies included in the review found that the poor experience with modern contraceptive methods explained the choice of women to use traditional contraceptive methods.Indeed in his study, Staveteig [29] pointed out that the bad experience with modern contraceptive methods explained the choice of women toward traditional contraceptive methods.

Interpersonal Level 1) Factors related to the couple
In this systematic review, couple-related motivation factors were identified.
Three studies have identified the husband's opposition to the use of modern contraceptive methods [24] [27] [29].Thus, for Mathe [27], the main reasons for using traditional methods were lack of knowledge, fear of side effects, religious Umoh and Abah [24], their study reported that the main factors for using the traditional planning method were education, side effects, age, and husband's opposition.Therefore, the opposition from husbands or partners and religious opposition also appeared to have been underreported in the GDHS [29].Communication within the couple was also identified as a motivating factor in the choice of traditional contraceptive methods.Two studies included in this review identified it [28] [31].For those authors, the results indicate that traditional methods are associated with greater discussion of family planning [31].In addition, family planning discussions during child welfare clinics or with one's spouse, the desire to space children were predictive of clients' intention to adopt family planning in the future and the rhythm method was the most patronized [28].

2) Religious considerations
Two studies included in this systematic review [27] [29] identified religion as a motivating factor to choose traditional methods.For example, in Mathe's paper [27], religious considerations were a motivating factor in the decision to use traditional contraceptive methods, while for Straveteig [29], religious opposition was also identified as a factor in using traditional methods.

Organizational Level 1) Accessibility
In this review, accessibility was identified as a motivating factor in women's choice of traditional contraceptive methods in sub-Saharan Africa [19] [25] [29].
Bekele & Fantahun [25] found that additional reasons for the use of the standard day method were the fact that it is available without cost to the individual (n = 5, 2.7%) and because it is a natural method (n = 5, 2.7%).Therefore, the traditional methods are mainly used, associated with knowledge, availability, and accessibility [19].

2) Availability
Of the 13 included in this review, four have the availability of traditional contraceptive methods as a factor of choice [19] [22] [25] [29].Furthermore, the use of traditional methods was associated with their availability [19], and natural methods are perceived as free, discrete, always available, and typically not requiring a visit to a health center [22].Thus, despite additional prompting on cost and access, no additional cost or access cases posed a barrier were found [29].

Discussion
The objective of this systematic review was to identify the preferences and motivations of women who use traditional contraceptive methods in sub-Saharan Africa.Several preferences and motivations were identified.Motivations were grouped according to the different levels of the SEM.The main traditional planning methods were abstinence, withdrawal, breastfeeding, rhythm method and herbal medicines.Many studies have shown women's preferences for traditional methods in sub-Saharan Africa.For example, among sexually active adolescent girls surveyed in Nigeria, 57 percent reported current traditional method use [32].In the Democratic Republic of Congo, more than 64 percent of a sample of postpartum women considered themselves current users of natural methods [27].This result is close to that found in Ethiopia.Meanwhile, traditional methods such as the calendar method, lactational amenorrhea method (LAM) and withdrawal were mentioned by 21.3%, 31% and 20.2% respectively of married women in a study conducted in Ouagadougou, Burkina Faso [33]; many women were classified as having an unmet need for family planning by the DHS [22].This review found that certain socio-demographic variables such as education level, residence, cognitive factors, and economic status were identified as motivation factors for choosing traditional contraceptive methods.These results corroborate those of Rossier & Corker [23], for whom the use of traditional methods is higher among women who wish to limit childbearing and women with a higher level of education, wealthier women living in urban areas.Therefore in their study, Gueye and Speizer [34] found that at the individual level, women's belief in these myths is negatively associated with the use of modern contraception.Regarding religious reasons, this result is similar to those of the WHO.Indeed, the reasons mentioned by couples were religious or philosophical [35].Also, religious affiliation determines traditional contraceptive methods since the Catholic Church allows some forms of traditional contraception (periodic abstinence, cervical mucus, temperature method) [15].On the other hand, a study in Ethiopia showed that women who had their husband's support had more than twice the chance to use contraception than those their pairs who did not [33].
Regarding the factors related to the organizational level, results showed that the availability, accessibility of natural methods increased their use.One study revealed a similar result.Indeed, natural methods are seen as free, inconspicuous, always available and generally do not require a visit to a health center [36] [37].Another study found that traditional contraceptive methods were related to users' ability to practice effectively [35].Factors about other forms of contraceptive methods, especially modern, are close to those of other authors.Supply-side issues are well known [38], including limited choice of methods, poor quality of care in health centers, long waiting times and frequent stock-outs, and the difficulties of using these modern methods [35].The cost of modern contraceptive methods is another reason, although often subsidized, would lead some users to traditional contraceptive methods [22].
Knowledge itself is the source of misinterpretations that lead to risk-taking.For example, it appeared that students inferred from information retained from their biology course on ovulation mechanisms that it was sufficient to protect them during this restricted period without considering the risk of irregular cycles [37].Furthermore, although being single or widowed is a barrier to choose traditional methods [25], this result is quite different from that found by WHO, for whom not being married increased the likelihood of choosing traditional methods [4].

Conclusion
This systematic review allowed us to identify preferences and motivations for using traditional contraceptive methods in sub-Saharan Africa.The results showed that women's choice of traditional contraceptive methods is multifactorial.Factors to use can be grouped into individual, interpersonal and organizational factors.These results help to improve women's knowledge and attitudes about family planning.In addition, these results will make it possible to better estimate the contraceptive prevalence rate by taking contraceptive methods into account in demographic surveys and rethinking the choice of women using traditional methods.
