It is recognized that for the improvement of the health of mothers and children, it is necessary to avoid births that are too close together, but rather to give birth with a spacing of two years [1] . Many studies have found that children born before this interval do not have a high chance of surviving [2] .

The experience of many countries in Latin America and Asia (South Korea, China, Singapore, Indonesia, etc.) shows that the first step towards a demographic dividend is the gradual and rapid decline in fertility through investments in family planning, child health and girls’ education [3] . Guaranteeing access for all populations to preferred methods of contraception makes it possible to strengthen several human rights such as the right to life and liberty, freedom of opinion and expression and the right to work and employment education, while bringing other important benefits in health, and in other areas. The use of contraception protects women, especially adolescent girls, from risky pregnancies that pregnancies can represent for their health and when births are spaced less than two years apart, the infant mortality rate is 45% higher than the mortality rate when births are 2 to 3 years apart, and 60% higher than the mortality rate when they are four years or more apart [4] . Contraception offers a range of potential benefits in areas other than health, ranging from expanded opportunities for women’s education and empowerment, to sustainable population growth and the economic development of countries [5] .

In addition, contraception could prevent approximately 104,000 maternal deaths each year, a reduction of 29% [6] . It can reduce child mortality by almost 10%, if it is available to us who need it [7] (UNFPA and the Population Reference Bureau, 2014). The maternal ratio is estimated at 549 per 100,000 live births; therefore one woman in 29 is at risk of dying from maternal causes during childbearing ages [8] . Recent figures on police infant deaths were 97 deaths per 1000 live births; the same report gives the infant and child death rate of 158 per 1000 live births. The total fertility rate is 6.6 children per woman for rural areas and 5.4 children in urban areas [7] .

In 2019, out of 1.9 billion women of reproductive age (15 - 49 years) in the world, 1.1 billion need family planning; of these, 842 million use contraceptive methods, and 270 million do not have access to the contraception they need [9] [10] . The proportion of women of reproductive age (15 - 49) using modern methods of family planning―Sustainable Development Goal indicator 3.7.1―was 75.7% globally in 2019; however, less than half of family planning needs were being met in Central and West Africa [9] .

A single contraceptive method, condoms, can both prevent pregnancy and the transmission of sexually transmitted infections, including HIV. Contraception strengthens the rights of people to choose the number of children they wish to have and to determine the spacing of births [5] .

Among married women of childbearing age, the prevalence of modern methods of contraception increased worldwide between 2000 and 2019 by 2.1 percentage points, from 55.0% (95% CI: 53.7% - 56.3%) to 57.1% (95% CI: 54.6% - 59.5%) [9] . Despite all these progressions, a slow increase is observed, and this can be explained, among other things, by: the limited choice of methods; limited access to services, especially for young people, poorer populations and unmarried people; fear or experience of side effects; cultural or religious barriers; the poor quality of the services available; biased opinions of users and providers against certain methods; and gender-related barriers in accessing services [5] .

Moreover, scientific work has shown that age, religion, level of education, spouse’s authorization and place of residence [11] , being a woman with decision-making power, having knowledge about modern contraception, having an income-generating activity and satisfaction with the quality of contraceptive services had an influence on the use of modern contraception [12] .

Nowadays, any family planning policy aims to bring needy women to use modern methods of contraception [3] . Despite the many initiatives to improve the use of family planning (FP) such as subsidies and community-based distribution of contraceptive products across Africa, modern contraceptive prevalence in 2016 was 13% in Africa West against 46% and 59% respectively in North Africa and South Africa. In Burkina Faso, this prevalence was 20% for the same year [13] . For example, Guinea is still one of the countries where the rate of use of modern contraception is the lowest in sub-Saharan Africa (11%1 in 2018). However, the country adopted a national population policy in 1992, revised in 1996 and in 2018, which has been implementing several programs in the field of family planning for years [3] .

Since 1970, the DR Congo has been characterized by one of the highest growth rates in the world, more than 3% [7] . Rapid population growth (>2%) and high fertility are a threat to the well-being of the poorest individuals and societies in developing countries [14] .

In DR Congo, seven out of ten households are poor. Modern contraceptive prevalence was 5.4% in 2010. The results of the 2013 demographic and health surveys show a prevalence of 8% across the country, and 15% in urban areas compared to 5% in rural areas [15] .

Due to high levels of maternal mortality and rapid population growth, the government has identified family planning as one of six interventions in its plan to accelerate progress towards achieving Millennium Development Goals 4 and 5. Recent surveys show that the fertility rate is 6.3; a quarter of women in the population of the DRC do not wish to become pregnant but do not use contraception, which led to the establishment of a strategic plan, developed over a period of 12 months in order to increase modern contraceptive prevalence from its current level estimated at 6.5% to 19% by 2020.

Currently, access to family planning services is limited, particularly in rural areas. Of the 516 health zones, only less than half of the health zones (46 percent) have family planning services. Although part of the minimum package of basic health services activities are integrated, family planning is often a neglected component [16] [17] .

In the province of Kongo Central, especially in the arearural health center of Gombe Matadi, the modern contraceptive prevalence in 2019 is considered very low at 29%. The male condom remains themethod best known and used by the women surveyed, the most cited source of information on family planning was the health personnel. Lack of information, side effects and high cost were cited as reasons for not using modern contraceptive methods in both the surveyquantitative than during focus groups. Factors associated with the low use of modern contraceptive methods in this region were lack of knowledge of modern contraceptive methods, long distances to travel bythe woman to health training (FOSA), and the fact of displaying an unfavorable attitude to the use of Modern Contraceptive Methods [18] .

In the province of Kasaï-Oriental, all health zones integrate activities related to the health of mothers and children, among other family planning, on the one hand, and on the other hand all the inputs of these activities. are permanently available and given free of charge [15] . However, the observation remains bitter because in most households we notice close births. To improve the rate of use of modern contraception, it is necessary to identify the levers on which to rely. It is in this perspective that the present study was carried out in order to determine the knowledge and practices of contraception in the health zone of Kansele, city of Mbujimayi.

In Table 1, the female sex was in the majority with 219 out of 249% or 87.95% against 12.05% of the male sex. Among our respondents those aged between 21 - 26 years were more represented with 89 out of 249% or 38.55%. Majority of our respondents were at the secondary school level with 146 cases or 58.63%. The most dominated religion in our studies was that of the church of revivals with 126% or 50.60%. Traders were more represented 87% or 34.94%, most of our respondents had 5 more children or 43.78% and those who wanted to have an inter-birth interval greater than 2 were in the majority or 83.53%.

According to Table 2, the majority of the surveys had already heard of contraception with 230% or 92.37%, the most cited channel was health personnel with 130% or 56.52%, most of our surveys defined contraception as being methods or medication for birth space with 177 or 76.96. The majority of respondents were for contraception with 179% or 77.84% and the reason for refusing contraception was the fear of complications related to contraception with 21% or 41.18%. The majority of respondents had knowledge of contraceptive methods with 190% or 82.61%. The calendar was the contraceptive method best known by respondents with 62% or 32.64%.

In analyzing Table 3, the majority of the surveys had knowledge of the sources of supply with 175% or 92.11%, the health structure was the place of supply known with 120% or 68.58%. The majority of our surveys did not have easy access to contraceptives with 97% or 55.43%.

Regarding Table 4, the majority of our respondents wanted to have more than 6 with 140 or 60.87%. Half of respondents or 51.30% had used contraceptive methods during the last 12 months; Most of respondents, 60.17%, used natural methods. From this table, among the kinds of natural methods used, the calendar came first, 73.24%. Most respondents used condoms, i.e. 31.91%.

As for Table 5, among the respondents who had used contraceptive methods, only 20% or 16.95% had side effects and the most cited side effect was bleeding 15% or 75%. All of the respondents, i.e. 100%, find family planning important. Almost half of them, i.e. 53.04%, said that planning had the advantage of birth spacing, the majority of respondents, i.e. 79.57% said family planning was a matter for the couple.

Finally, in Table 6, the Relationship between the profile of respondents and the use of contraception, Profession, level of education and desired inter-birth interval are associated with the use of contraception (p < 0.005).

Concerning the sex, our study shows a predominance of the female sex, that is to say 87.95% with a sex ratio of 0.14. These results are far superior to those found by Léon Bijlmakers during a study conducted in Mali where 39% of respondents were female, the sex ratio was 1.4 [19] .

Our study shows that the age group of 21 and 26 years is more represented with 38.55%. These results corroborate a study conducted by Matungulu C, et al. in Lubumbashi which indicated that the most represented age group was between 18 and 29 years old with 37% [14] . Contrary to the results found in Cameroon, the most represented age group was that of 40 to 49 years with 26.9% [20] .

With regard to the level of study, our results show that 58.63% of our respondents have a secondary level. These results differ from those found by Lenan in Tachad where 96% of respondents had no level of education’ study. However, these respondents with a low level of education had a risk twice as high of not using contraception OR = 2.4922; CI: [1.4672; 4.2673] and p = 0.0003 [21] .

In our study, 50.60% of respondents were revival churches. Faith and family planning interact in complex ways at the level of governments, civil society, communities and individuals. If all stakeholders better understand how it works, secular actors, religious leaders, and faith-based organizations can move family planning forward more effectively. Leaders influence the behaviors of people seeking care and faith-based organizations provide a wealth of care information, services and products. Faith-based organizations inspire trust and credibility through their continued presence with all citizens, especially in hard-to-reach or conflict-affected communities where other actors only visit sporadically. Faith-based organizations help contextualize family planning interventions and concepts using language and approaches appropriate to the culture and beliefs of the communities involved. When faith-based organizations take the lead in supporting family planning, they can help nurture strong family planning incentives [22] [23] [24] .

A NURHI evaluation found a 30% increase in contraceptive use among women exposed to family planning messages from religious leaders compared to women who were not exposed to these messages. In Kenya, the number of family planning consultations increased significantly after the Christian Health Association of Kenya (CHAK) implemented a project involving six health facilities run by faith-based organizations to increase service delivery family planning volunteers in western Kenya, in partnership with volunteer religious leaders and community health workers [25] . To be effective, family planning programs and policies must take religion into account with intelligence, openness, persistence, and creativity [26] . Our results show 34.94% of respondents were traders, 47% unemployed and 4.42% liberal. Unlike the studies of Lenan S in Tachad conducted in Chad, 91.6% of respondents were unemployed. This could be because most of the population trades [21] .

Regarding the number of children, our results show that 43.78% of respondents had more than five children. Concerning the inter-birth interval and the use of contraception, our study shows that 59.09% of respondents who did not use contraception were likely to wish to contract an interval before their child celebrates their first birthday. There is a statistically significant association between these two variables (p-valued = 0.0386 < 0.05; OR = 2.0221; CI = 1.321; 4.147). Thus, the risk of contracting an interval before their child celebrates their first birthday is twice as great as in those who did not use contraception. These results are slightly lower than those of Badose Musimwa et al. who found that in 31% of cases, the desired interval was greater than 3 years, i.e. 63.7%. This difference is explained by the fact that couples link children to wealth and prefers to have a lot of them [27] .

Our field investigations showed that 92.37% of respondents had already heard of contraception; this through the channel of the health center or 56.52%; 76.96% of respondents defined contraception as a method or medication for spacing births; 77.83% were for contraception; 41.18% of respondents were afraid of complications related to contraception as the cause of non-acceptance. This fear is often motivated by the transmission of false information about contraception. A study explains that even teenagers and teachers have misconceptions about contraception. These results indicate the likely low popularization of FP among adolescents and teachers [28] .

Contraceptive misconceptions aren’t unique to teens. Ho & Wheeler (2018) [29] in a study carried out in eastern DRC, highlighted misconceptions about some modern methods of contraception by providers, users and community members. Yoost (2014) [30] reported that even in developed countries, misconceptions persist regarding IUD use, particularly among young people and nulliparous women. Apart from these observations, the judgmental attitude of health care providers and the lack of confidentiality can deter the use of contraception by adolescents [31] .

The results have revealed that 82.61% of respondents had knowledge of types of contraception; 32.64% had knowledge of the calendar as a type of contraception; 92.11% knew the source of supply among which the health structures were known, i.e. 68.58%; 55.43% of respondents did not have easy access to the source of contraceptive methods. This is explained by the fact that the majority of respondents already had knowledge of the types of contraceptive methods during the awareness campaign by community relays. Our results are close to those found by Matungulu C, et al., they had respectively (84%, 37%, 88%, 73%, and 50%) in a study carried out in Lubumbashi on the determinants of the use of methods contraceptives in the Mumbunda health zone [15] .

Asked about the number of children desired, the respondents considered having more than 6, or 60.87%. These results differ from that of Lenan in Tachad where 92.6% of respondents wanted to have children from 3 to 6 children. This discrepancy is explained by the fact that the majority of respondents who wanted fewer children, sought to control their births [21] .

Our results stipulate that almost half of the respondents, i.e. 52.21%, used contraceptive methods. Most of the respondents, 60.17%, used natural methods. Among the kinds of natural methods used, the calendar came first with 73.24%, but for the artificial methods, most respondents used condoms, with 31.91%. Similarly, a health demographic survey on the determinants of the low use of contraception in the Dibindi Health Zone had shown that the male condom was the method most used by 35% of the population [15] .

These data do not corroborate with those found by Mustafa G, and al, in which 68% of respondents used contraceptive methods and a small proportion of respondents who used contraception [32] . Compared to a study conducted specifically on the use of contraceptive methods by women with HIV, the contraceptive prevalence among HIV-infected women was 62.5% [33] . Several studies in sub-Saharan Africa have evaluated the use of modern contraceptive methods among HIV-infected women. The proportion of HIV-infected women using contraceptives in this study was similar to that seen in a South African study. In this prospective survey that included 290 women living with HIV in Durban, contraceptive prevalence was 63% [34] .

Among the types of side effect encountered, bleeding was the most represented at 75%. Most respondents had not interrupted the use of contraceptive methods. These results do not corroborate those of EDSMV.BAMAKO where ¾ of respondents had had metrorrhagia and abdominal pain as a side effect, and 41% of respondents had interrupted the use of contraceptive methods because of adverse effects and did not reiterate their experiences.

All of the respondents, i.e. 100%, find family planning important. Almost half of respondents or 53.04% say that birth spacing is the advantage of family planning. The majority of respondents, i.e. 79.57%, attribute the family planning affair to the couple. Family planning is one of the cheapest, most cost-effective interventions with the most lasting impact on health. Yet it is often overlooked as a key strategy for improving health in urban areas. Although family planning services are less available in rural areas and in the most isolated regions of less developed countries, the poor who live in urban areas have more difficulty accessing family planning services than wealthier residents, for various reasons related to the social, cultural and financial context. Given that half of the world’s residents now live in urban areas, improving access of the poor to family planning services in urban areas should be a high priority, especially considering that the majority of urban residents in many countries live on less than US$2 a day [9] .

Bivariate analyzes show that: the respondents who were without profession, those who had a low level of education and those who wanted an inter-birth interval of less than 2 years were proportionally likely to not use contraception (p < 0.005) during the last 12 months. On the other hand, the benefits of family planning, free contraceptives, the approval of their husbands and moral obligation were the reasons for the use of the voucher by women. The desire to become pregnant, their husbands’ opposition (to contraceptives), women’s reluctance, women’s lack of knowledge of contraceptives and intervention-related factors have been cited as reasons for not using vouchers [35] . Another study notes that the main obstacles to contraception are: lack of reliable and adequate information, misconceptions about contraception, fear of side effects, illiteracy, male decision-making power, religious prohibitions and socio-cultural contradictions [36] .

The population of the health zone of Kansele, town of Mbujimayi have knowledge of contraception (92.37%), but the use of the latter is relatively low. However, this use was influenced by the level of study, the profession and the desire for an inter-birth interval of less than 2 years.

Therefore, the substantial improvement in modern contraceptive practice in the Kansele health zone (city of Mbujimayi) must necessarily go through an ambitious and well-coordinated program. This program should focus its interventions on targeted and multi-channel awareness, coupled with the supply of a wide range of contraceptive products at affordable costs.

We thank the authorities of the Health Zones for having facilitated data collection for the investigators.
