Reasons for nonuse of contraceptive methods by women with demand for contraception not satisfied: an assessment of low and middle-income countries using demographic and health surveys

Abstract

Background

Nonuse of contraceptive methods by women in need of contraception may impact their sexual and reproductive health. The aim of this study was to describe the reasons for nonuse of contraception among women with demand for contraception not satisfied in low and middle-income countries (considering both overall countries and various subgroups of women).

Methods

We used the latest Demographic and Health Survey data from 47 countries. A descriptive analysis of the reasons for nonuse of contraceptive methods was performed among sexually active women with demand for contraception not satisfied. The prevalence of each reported reason was also evaluated according to marital status, womanā€™s age and schooling, area of residence, wealth index, and parity. Wealth-related absolute inequality for each reason was also evaluated using the Slope Index of Inequality. A pro-rich inequality pattern means that the reason is more prevalent among the richest women while a pro-poor means the reason is more common among the poorest ones.

Results

On average, 40.9% of women in need of contraception were not using any contraceptive methods to avoid pregnancy. Overall, the most prevalent reasons for nonuse of contraceptives were ā€œhealth concernsā€ and ā€œinfrequent sex,ā€ but the prevalence of each reason varied substantially across countries. Nonuse due to ā€œopposition from othersā€ was higher among married than unmarried women; in turn, the prevalence of nonuse due to ā€œlack of accessā€ or ā€œlack of knowledgeā€ was about two times higher in rural areas than in urban areas. Women with less schooling more often reported nonuse due to ā€œlack of access.ā€ Pro-rich inequality was detected for reasons ā€œhealth concerns,ā€ ā€œinfrequent sex,ā€ and ā€œmethod-relatedā€, while the reasons ā€œother opposed,ā€ ā€œfatalistic,ā€ ā€œlack of access,ā€ and ā€œlack of knowledgeā€ were linked to patterns of pro-poor inequality.

Conclusions

Family planning promotion policies must take into account the different reasons for the nonuse of contraceptive methods identified in each country as well as the contextual differences regarding women of reproductive age (such as social norms and barriers that prevent women from accessing and using contraceptives).

Plain English summary

The nonuse of contraceptive methods by women who need contraception may impact the lives of these women and the planning of their families. One example is unintended pregnancy and its possible implications. Research has identified several reasons for the nonuse of contraceptive methods. However, studies have mostly only focused on women who are married or who live with a partner. In this study, we included all sexually active women in each country; doing so allowed a more comprehensive overview of the reasons for why women whose demands for contraception are not satisfied do not use contraceptive methods. We presented the differences between the reasons for nonuse of contraceptives reported by partnered and unpartnered women. Data from 47 low and middle-income countries were obtained from the Demographic and Health Survey (DHS) Program for analysis. The results showed that, on average, about four out of ten women in need of contraception were not using any contraceptive methods. There was great variation among countries in the reasons reported. Overall, the most common reasons for nonuse were ā€œhealth concernsā€ and ā€œinfrequent sex.ā€ Nonuse due to ā€œopposition from othersā€ was more common among married women. It was noteworthy that wealthier women often mentioned ā€œhealth concerns,ā€ ā€œinfrequent sex,ā€ and ā€œmethod-relatedā€ as reasons for not using contraceptives. The present research is important in helping professionals from various fields understand why women who need contraception do not use contraceptive methods so as to offer guidance and provide adequate care.

Background

The nonuse of contraceptive methods by people who need contraception has been associated with potential implications at the individual, familial, community, and global levels. Sustainable Development Goals [1], as well as the proposal of maternal and child health indicators [2], have been essential in increasing the visibility of this topic and highlighting points for improvement. In addition, several agencies and organizations around the world have engaged in global efforts to finance actions that promote family planning, especially in low and middle-income countries (LMIC) [3,4,5].

However, despite these efforts, the sexual and reproductive rights of women are not always respected. Although there is evidence of progressive increases in the use of contraceptive methods [6], many women still face various barriers to contraceptive use [7]. It is estimated that 214 million women in LMIC in need of contraception do not use any modern contraceptive methods [8]. Considering that all women, as advocated by the Sustainable Development Goals, should have access to sexual and reproductive health services, understanding the reasons behind why this need remains unfulfilled is essential for action planning.

An investigation performed by Sedgh and Hussain [9] on 51 LMIC showed that among married women, the most frequent reasons for nonuse of contraceptives were low frequencies of sexual relations, and fears of side effects and potential health risks. However, a major limitation of that study is the absence of unmarried, sexually active women in the study sample. The reasons for nonuse are likely very different between married and unmarried women, and this is possibly linked to social barriers and other difficulties related to access to contraceptives that unmarried women face. However, literature concerning family planning lacks information regarding reasons, reported by the women themselves, for not using contraception. As discussed by Sedgh and Hussain [9], the analysis of the reasons for nonuse in different population subgroups may provide relevant information to support the design of specific initiatives. Added to that, there is increasing evidence in scientific literature of the importance of using measures that are not only expressed as aggregate data [10], that is, of evaluating the specificities of each country and the possible inequality contexts.

Considering the situation, the present work aimed to address this gap in knowledge. In addition to evaluating the reasons for nonuse of contraceptive methods by sexually active women with demand for contraception not satisfied in LMIC, subgroup analyses of the reasons for nonuse were performed to investigate possible barriers and to propose strategic priorities to improve womenā€™s sexual and reproductive health. Furthermore, the analyses of inequalities might identify what strategies may be more suitable for each subgroup.

Methods

We analyzed data from the Demographic and Health Surveys (DHS) Program for 47 countries. The study focused on the most recent surveys, with data collected in and after 2010, to provide a current overview of the topic investigated. The Multiple Indicator Cluster Surveys (MICS) were not included, since the data of interest could not be retrieved from these surveys in a manner that allowed for comparison. DHS are standardized surveys that use a cross-sectional design to collect data from LMIC. All surveys use similar questionnaires, methodology, and sampling strategies, which ensures the comparability of results. In general, the areas of interest are initially identified through censuses or other procedures. After that, households are selected based on pre-established methodological steps [11, 12]. The present analysis included the latest available DHS with information on demands for family planning and covered all sexually active women of reproductive age (15ā€“49ā€‰years) in each country. Six surveys that did not contain information on sexually active women living without a partner were excluded (Afghanistan 2015, Bangladesh 2014, Egypt 2014, Jordan 2012, Pakistan 2012, Yemen 2013).

Definitions and outcomes

The studyā€™s primary outcomes were the reasons reported by sexually active women of reproductive age (15ā€“49ā€‰years) (with demand for contraception not satisfied) for not using contraceptive methods. The indicator Demand for Contraception Not Satisfied utilizes the number of women who are not using any contraceptive methods in its numerator and the number of women of reproductive age (15ā€“49ā€‰years) in need of contraception in its denominator. In other words, the study included women who were in need of contraception but did not use any contraceptive methods. Women in need of contraception were defined as those who were sexually active and fertile, but did not intend to become pregnant in the next 2 years or did not know if or when they intended to become pregnant [2, 11, 13]. Sexually active women were defined as those who were married or lived with a partner and those who were not married but had sexual intercourse in the 30ā€‰days prior to the survey. Infertile women excluded from the study were defined as those who: 1) had never had a period or were amenorrhoeic in the 6 months before the survey even though they were not in the postpartum period, 2) were hysterectomized, and 3) had been married or in a stable relationship for 5 years or more but did not become pregnant despite a lack of contraceptive use [11, 14]. Although pregnant women who considered their pregnancies untimely or had not desired their pregnancies are generally classified as in need of contraception [11], they were also excluded from this study because being pregnant is one of the filters for the questions regarding the reasons for nonuse of contraception.

The reasons for nonuse were evaluated using the following question: ā€œYou have said that you do not want any (more) children. Can you tell me why you are not using a method to prevent pregnancy? Any other reason?ā€ The reasons for not using contraceptive methods were grouped into eight broad groups of reasons (see TableĀ 1 for details): 1) ā€œrespondent opposedā€ (i.e., the woman herself opposed contraceptive use), 2) ā€œother opposed,ā€ 3) ā€œlack of knowledge,ā€ 4) ā€œhealth concerns,ā€ 5) ā€œlack of access,ā€ 6) ā€œmethod-relatedā€ (inconvenient to use), 7) ā€œfatalisticā€ (or up to God, meaning that the woman feels that pregnancies are determined by fate), and 8) ā€œinfrequent sex.ā€ Because women could report more than one reason, each response category was analyzed separately.

Statistical analysis

Descriptive analyses were used to identify the main reasons for the nonuse of contraceptive methods among women whose demands for contraception were not satisfied in the various LMIC. When analyzing the reasons for nonuse, the countries were ranked according to the level of demand for contraception not satisfied: less than 30.0%, 30.0% to 50.0%, and more than 50.0%. Considering these coverage levels, the reasons for nonuse were also evaluated according to the following stratification variables:

  • marital status (married/union; unmarried sexually active);

  • womanā€™s age (15 to 19; 20 to 34; 35 to 49ā€‰years);

  • area of residence (urban or rural);

  • womanā€™s education (none; primary/elementary school; secondary or higher);

  • parity defined as the number of live births (0; 1ā€“2; 3 or more);

  • wealth index (in quintiles, with the first corresponding to the poorest 20% and the fifth to the wealthiest 20% in each country). The wealth index is calculated using principal component analyses which take into account characteristics of the household, ownership of selected assets, and educational attainment of the head of the family [15, 16].

In addition, inequality analyses were performed using the Slope Index of Inequality (SII). Instead of calculating the simple absolute difference in the prevalence of the outcome of interest in the wealthiest vs. poorest quintile, the SII measures the difference in predicted coverage using a statistical model for these quintiles. In other words, the SII takes into account the prevalence of the outcome of interest in the five wealth quintiles to estimate the absolute difference between the wealthiest and the poorest quintile [15, 16]. All statistical analyses were performed using the STATA 13.1 statistical package [17] and took into account the sample weights of surveys through the command ā€œsvy.ā€

Results

Considering the 47 countries analyzed, the mean prevalence of demand for contraception not satisfied was 40.9% (95% CI: 38.9ā€“43.0). Seventeen countries had a prevalence of demand for contraception not satisfied higher than 50%, and in five of these countries (Angola, Mali, Gambia, Guinea, and Chad), the prevalence was 70% or higher. The Republic of Chad had the highest prevalence (79.7%, 95% CI: 77.2ā€“82.1) (TableĀ 2). The two countries with the lowest prevalence of demand for contraception not satisfied were Colombia (8.6%, 95% CI: 8.1ā€“9.2) and Honduras (12.8%, 95% CI: 12.1ā€“13.5), both located in Latin America and the Caribbean.

Table 2 Overall description (countries information, prevalence of demand for contraception not satisfied and 95% CI)

ā€œHealth concernsā€ was the top reason for nonuse in 22 out of the 47 countries. In 18 countries (38.3% of the total countries), ā€œinfrequent sexā€ was the most prevalent reason (TableĀ 3). In Gabon, the same prevalence (17.4%) was recorded for both ā€œhealth concernsā€ and ā€œinfrequent sex,ā€ and the two were also the most common reasons for nonuse in this country. ā€œOther opposedā€ was the most prevalent reason in three countries (Senegal, Mali, and Guinea). In Gambia, ā€œrespondent opposedā€ was the most prevalent reason for nonuse whereas in Ethiopia and Niger, ā€œfatalisticā€ was the most common reason (Table 3).

Table 3 Reasons for nonuse of contraceptive methods (mean by coverage level, prevalence, and 95% CI)

The prevalence of the reasons reported were also different according to the level of demand for contraception not satisfied (Table 3). On average, ā€œhealth concernā€ and ā€œinfrequent sexā€ were the most common reasons for all levels of demand not satisfied, but the prevalence of these reasons was higher among countries with demand not satisfied below 30%. All the other reasons tended to be more prevalent among countries with higher demand not satisfied.

It is important to note that the most common reasons for nonuse of contraception varied greatly between countries. In the five countries with demand not satisfied of 70% or more, the most prevalent reasons for nonuse were: Angola - ā€œhealth concernsā€ (13.3%, 95% CI: 11.1ā€“15.9), Mali - ā€œother opposedā€ (26.4%, 95% CI: 22.7ā€“30.5), Gambia - ā€œrespondent opposedā€ (25.4%, 95% CI: 21.2ā€“30.0), Guinea - ā€œother opposedā€ (15.5%, 95% CI: 13.3ā€“18.0), and Chad - ā€œinfrequent sexā€ (18.0%, 95% CI: 15.7ā€“20.5).

Stratification provided an overview of the situation in the countries according to different subgroups of women. These analyses are presented by level of demand for contraception not satisfied: countries with demand not satisfied below 30% (Fig.Ā 1), from 30% to 50% (Fig.Ā 2), and above 50% (Fig.Ā 3). We also provide the stratified estimates for each reason by country in the supplementary material (see Additional files 1, 2, 3, 4, 5, 6, 7 and 8). These analyses reveal important differences on why some women do not use contraception.

Nonuse due to ā€œhealth concernsā€ was more frequently reported among women who were older, had higher levels of education, had more wealth, were married or living with a partner, had at least one child, and among those living in urban areas. ā€œInfrequent sex,ā€ the second most reported reason, was higher among those who had higher levels of education, had more wealth, were unmarried, and had no children. In all the coverage levels assessed, a difference close to eight percentage points was observed for the comparison between married and unmarried women in ā€œinfrequent sex,ā€ with the latter being more likely to mention this reason (Figs.Ā 1, 2 and 3).

There were no marked inequalities in the reporting of nonuse due to ā€œrespondent opposed.ā€ On the other hand, nonuse as a result of ā€œother opposedā€ occurred mostly among married women rather than unmarried women in all coverage levels assessed. However, the prevalence of this reason was higher among countries with higher demand not satisfied. For those with demand not satisfied of >ā€‰50%, ā€œopposition by othersā€ was reported by 15.1% of married women and 8.5% of unmarried women (Fig. 3) while for countries with demand not satisfied of <ā€‰30%, this reason was reported by 7.8% of married women and 3.6% of unmarried women (Fig. 1). In countries with demand not satisfied between 30 and 50%, there were higher inequalities observed in terms of wealth and education; poorer and less educated women were more likely to report this reason (Fig. 2).

Nonuse due to ā€œfatalistic,ā€ ā€œlack of access,ā€ and ā€œlack of knowledgeā€ were more frequently reported by women in the poorer groups, those with lower education levels, and those who lived in rural areas (Figs. 1, 2 and 3). ā€œFatalisticā€ as the reason for nonuse was also systematically higher among older women and those with higher parity. ā€œLack of knowledgeā€ was also about twice higher in rural areas than in urban areas for all levels of demand for contraception not satisfied evaluated. Nonuse due to ā€œlack of accessā€ was also higher in rural areas than in urban areas for all levels of demand for contraception not satisfied (<ā€‰30%, 30ā€“50% andā€‰>ā€‰50%), corresponding to, respectively, 5.3%, 3.5%, and 4.6% in urban areas, and 6.3%, 6.1%, and 8.0% in rural areas (Figs. 1, 2 and 3).

Regarding the inequality among the reasons for not using contraceptive methods by country, determined by the SII, the results clearly show that nonuse due to ā€œhealth concerns,ā€ ā€œinfrequent sex,ā€ and ā€œmethod-relatedā€ showed pro-rich inequality patterns (SIIā€‰>ā€‰0) in most countries, which means that these reasons were more prevalent among the richest women (see AdditionalĀ fileĀ 9). On the other hand, the reasons ā€œother opposed,ā€ ā€œfatalistic,ā€ ā€œlack of access,ā€ and ā€œlack of knowledgeā€ were linked to patterns of pro-poor inequality (SIIā€‰<ā€‰0), which means that these reasons were more prevalent among the poorest women.

Discussion

This study evaluated the reasons for nonuse of contraception among women with demand for contraception not satisfied in 47 LMIC. The mean prevalence of demand for contraception not satisfied in this group of countries was 40.9% (95% CI: 38.9ā€“43.0). Regarding the reasons for nonuse by women with demand for contraception not satisfied, it is noteworthy that ā€œhealth concernsā€ and ā€œinfrequent sexā€ were the most prevalent reasons in many countries. Five countries, all of which are located in Africa (Angola, Chad, Gambia, Guinea and Mali), presented prevalence of demand not satisfied of >ā€‰70.0%.

In West and Central Africa, where many of the low-income countries analyzed are located, a study identified inequalities and a higher probability of long-term contraceptive use by the wealthier women in this region than by the poorer women [18]. This underscores the need to empower women and the importance of learning about the unique characteristics of each region, for example.

Conversely, Colombia (8.6%, 95% CI: 8.1ā€“9.2) and Honduras (12.8%, 95% CI: 12.1ā€“13.5), located in Latin American and the Caribbean, had the lowest prevalence of demand for contraception not satisfied. The literature on Latin America and the Caribbean describes a decline in fertility rate over time [19] as well as other demographic changes, such as aging populations [20]. In this context, reproductive health policies, among other strategies, play an important role in family planning [21]. Some advances also may be attributed to the availability of a variety of contraceptive methods [20]. It is possible that these various processes together may explain the low levels of demand for contraception not satisfied identified in Colombia and Honduras. However, it is important to highlight that the low prevalence of demand for contraception not satisfied in these countries do not reflect an ideal scenario, although some of these countries have low levels of demand not satisfied, the optimal prevalence for this indicator would be zero. All women in need of contraceptives should have access to them.

Practicing contraception does have side effects, and nonuse due to fear of these consequences was addressed in the reason ā€œhealth concerns.ā€ Conversely, one possible result of not using any contraceptive methods is unintended pregnancy [22]. It should be noted that, besides the associated stigma, unintended pregnancy may have other consequences for the woman and her family of which the general population is often unaware. Such consequences may include negative health outcomes for the woman (morbidity and mortality) and the child (for example, impact on prenatal care and breastfeeding) as well as social costs [23,24,25]. However, it should be noted that unintended pregnancies are not always regarded as negative outcomes by women and their families, which shows the importance of contextual variables [26]. Nevertheless, studies also suggest that the possible side effects of contraceptive use are few compared to the possible risks resulting from some types of pregnancies [27,28,29].

Women in the highest wealth quintile had a higher mean prevalence of nonuse due to ā€œhealth concern.ā€ This raises the question of whether these women have access to a wide range of contraceptive methods or whether this access is restricted to only a few contraceptive options that may not meet individual demands. In this study, we showed that some participants mentioned ā€œmethod-relatedā€ reasons for not using contraceptives which may indicate dissatisfaction with the existing methods of contraception; this supports the need for a wider range of contraceptive options, as pointed out by Barot [30]. In addition, health care professionals need to provide evidence-based information about the methods of contraception and listen to womenā€™s beliefs and opinions so that women can make informed decisions about the most appropriate contraceptive methods for them.

Women who reported ā€œinfrequent sexā€ as a reason for nonuse may consider themselves less likely to get pregnant, as suggested by Sedgh and Hussain [9] and Barot [30]. Over time, women have taken on new roles in society, and there is evidence of declining unmet contraceptive needs [6, 31]. Work opportunities may sometimes lead to geographical relocation [9, 32, 33], which may then cause couples to live apart. In this situation, the professional advantage obtained may come at a personal cost with regards to womenā€™s reproductive health decisions. These aspects may explain, at least in part, some of our results (for example, why women who were in the highest wealth quintile (fifth quintile) and had more schooling had a higher mean prevalence of nonuse due to ā€œinfrequent sexā€). It is important to provide these women information on the functioning of the reproductive system and the importance of contraceptive use, and offer them support for reproductive health decisions. Long-acting reversible contraceptives may be a good alternative for these women.

Some women avoid using contraceptives due to ā€œother oppositionā€ which can be their partners, other people from their families or communities, or even their religions. Women sometimes face obstacles in their relationships with their partners (for example, difficulty in negotiating contraceptive use), and this can be inferred from the stratified analysis since in general, the mean prevalence of this reason was higher among married women than among unmarried women. This is striking, as all women should have the right to make their own reproductive decisions. This also highlights the need to empower women, as doing so will allow them to have autonomy over their own bodies and lives and make informed decisions regarding contraception [34].

It is possible that cultural and personal issues, which were not captured in the health surveys, may also be involved in womenā€™s decisions to use or not use contraceptive methods. Some women are engaged in homoaffective relationships, which is another aspect that is not evaluated in the surveys. In this case, there would be no concerns regarding using contraception to prevent pregnancy, although the use of condoms, for example, would be essential in preventing sexually transmitted infections. In regard to women who reported a ā€œfatalisticā€ or ā€œrespondent opposedā€ reason, it is possible that this involves beliefs or other personal issues that require further investigation.

In countries where nonuse due to ā€œlack of accessā€ is high, investments made to increase the availability of contraceptive methods is essential. Beyond access, it is also imperative that health care professionals are prepared to provide information on the specific characteristics of existing contraceptive methods to ensure that people can choose the method that best fits their individual needs [23, 35, 36]. However, it is noteworthy that some women face a variety of barriers [7, 37] when attempting to fulfill their reproductive health needs.

Some limitations of the present study must be addressed. First, since countries without information on unmarried, sexually active women were excluded, some regions may have been underrepresented. In other words, the group of countries that were investigated may not represent the entire region or all LMIC. In addition, in presenting means, the data may differ from individual results, as substantial variations were identified. In this sense, it is relevant to pay attention to the data from each individual country to understand what these data reveal about the local reproductive health situation. Being currently pregnant was a filter for the DHS questions regarding reasons for not using contraceptives. However, it is important to understand whether these women had a contraceptive failure or whether they were not using any contraceptive methods (and what the reason was, should they have not been using any methods of contraception). Another limitation is that, by grouping reasons such as nonuse due to religious concerns and nonuse due to partner opposition similarly under ā€œother opposedā€ (this strategy was adopted because very few women mentioned religious prohibition), it is impossible to detect whether religious constraints predominated in some countries over other personsā€™ opposition. As well, we cannot rule out the possibility of differences in individualsā€™ understandings and interpretations of the survey questions, and thus in the way the themes under investigation were reported.

Nevertheless, the present study also has many strengths, such as the use of recent data (2010ā€“2017) for a large number of countries and the inclusion of information about both married and unmarried women. This provides a comprehensive overview of the reasons for nonuse of contraception, and is a step forward in relation to previous studies [9, 11]. In addition, the present study only focused on, for the calculation of the indicator, women in need of contraception and provided knowledge on reasons why contraceptive methods are not used, with stratification by subgroups. By directly pinpointing groups in need of interventions, we can better fulfill the contraceptive needs of women.

Understanding the reasons behind why women are not using contraceptives has many potential implications for reproductive health policies. Identifying the opinions of women themselves on the topic and detecting possible difficulties they face may serve as a tool to help professionals from diverse fields keep in mind the importance of increasing access to reproductive health services, empower women to make their own reproductive decisions, and provide necessary information and support to ensure that women are capable of overcoming barriers.

Conclusions

ā€œHealth concernsā€ and ā€œinfrequent sexā€ were the most frequent reasons for nonuse of contraception in many LMIC, though the prevalence of each reason varied across different countries and subgroups of women. To decrease the prevalence of demand for contraception not satisfied, it is necessary to design, test and implement contextualized interventions. Generally, it is necessary to listen to womenā€™s beliefs and opinions, provide women with more information on the importance of using contraceptives to avoid unwanted pregnancies and sexually transmitted infections, inform them of the contraceptive methods available and their side effects, and increase their access to a wide range of contraceptive methods.
