Introduction
Kenya has a high fertility rate of 3.9 births per woman [
1], a teenage pregnancy rate of 18% [
1] and over 120,000 unsafe abortions annually [
2]. Family planning (FP) is a key intervention for preventing unplanned pregnancies, unsafe abortions, and maternal death [
3]. Kenya, in line with sustainable development goal 3, is implementing FP programmes aimed at universal access to sexual and reproductive health services by 2030.
Most FP interventions have been targeted towards women, who are the primary users of contraceptives. The lack of involvement of male partners results in opposition to self or partner’s FP use [
4‐
6] due to their low level or lack of knowledge on FP. In Kenya, fear of side effects and infidelity among women using contraceptives [
6,
7], misconceptions and socio-cultural concerns on FP [
7] are some of the reasons for male opposition to FP use. Studies show that women often opt to use contraceptives covertly due to non-supportive spouses and relatives [
4‐
6,
8]. However, involving both women and their partners is a strategy that promotes contraceptive acceptance, uptake and continuation [
4,
9], couple communication and gender-equitable attitude [
10]. Better knowledge on FP by male partners promotes cooperation; especially on the methods requiring male involvement like condoms.
Moreover, women have resorted to covert contraceptive use (CCU) due to fear of reprisal from the partner [
11], religious beliefs [
12] and withdrawal of support [
13]; reasons that may reduce the uptake of FP for some women. Covert contraceptive use may expose women to gender-based violence if discovered [
4,
5,
14] and could result in contraceptive discontinuation or change to a less preferred method [
15] hence eroding the gains in increasing the contraceptive prevalence rate (CPR). A study in Senegal found that CCU is a barrier to contraceptive continuity with women deprived of appointment reminders [
16] making it difficult for women to follow their contraceptive use hence increasing the risk of discontinuation. Similarly, with a rate of discontinuation at 31% [
17], Kenya needs to address factors associated with and the role of CCU in discontinuation.
CCU is common in male-dominated settings where women lack the autonomy to make choices on their health [
18]. Studies have shown a positive association between women empowerment and autonomy and their use of contraceptives [
19‐
21]. Women should be free to decide and choose their preferred FP method even in settings with better male involvement and spousal communication on FP [
22,
23]. However, covert use of contraceptives could highlight the discordance between women’s ability to decide on their sexual reproductive health and societal infringement of their right to choose. Previous studies in sub-Saharan Africa have shown that covert contraceptive use is associated with low levels of education [
24,
25], urban residence [
24,
26], richest wealth quintile [
4,
24,
27] and polygamous marriage [
24].
Covert contraceptive use is widespread in sub-Saharan Africa, with a prevalence of 2.6–53% [
24‐
26,
28,
29]. In Kenya, previous studies based on the 2008/09 [
24] and 2014 [
1] demographic health survey (DHS), and in Nyanza region [
30] found that 8.7, 7.8 and 9% of married women used contraceptives without their partners’ knowledge, but did not explore the associated factors. However, these studies reported lack of partners involvement [
31], male partners resistance to contraceptive use [
32], differences in fertility intentions [
32] and unsupportive spouses [
8] to be the reason for the CCU.
While covert use of contraceptives may contribute to the overall increase in modern contraceptive prevalence rate in Kenya, which currently stands at 58.1% [
33], it could also indicate the barriers Kenyan women encounter in deciding and using FP methods and may be contributing to the 18.6% unmet need for FP [
33]. With the paucity of information on CCU in Kenya, it is important to provide up to date evidence on the extent of CCU and associated factors to help in understanding contraceptive use in Kenya and contribute to informing FP interventions and policies towards Kenya’s FP goal of modern CPR of 66% by 2030 [
34]. Furthermore, these findings could contribute to addressing CCU by promoting partner involvement hence reducing the risk of gender-based violence resulting from non-disclosure of contraceptive use, allaying fears of side effects, infidelity, misconceptions, and socio-cultural concerns on FP and overall increasing partners’ knowledge on FP and contraceptive use.
Discussion
The present study found a 12.2% prevalence of CCU among married women in Kenya. The prevalence was high among older, uneducated, poorest, and rural women, and among women who neither had children nor wanted for more children. The commonest methods of contraceptives used covertly were injectables and implants. Education levels, wealth, county of residence, rural residence, parity, and age at sexual debut were associated with CCU.
The prevalence of CCU in SSA ranges from 2.6 to 20.2% [
24]. In our study, about one in ten women used contraceptives covertly, which signified an increase in the prevalence of CCU from 8.7%% [
24] and 7.8% [
1] reported in DHS of 2008/09 and 2014 respectively. The CCU prevalence is also higher than the 9% reported in a previous study in the Nyanza region of Kenya [
30]. The high and increased prevalence of CCU observed in this study depicts a gap in partner involvement in contraceptive use and difficulty in communication on contraception [
31,
32,
37], which are some of the main drivers of CCU in Kenya [
37]. Moreover, our prevalence was higher than in Ethiopia (8.7%) [
28] but lower than in Uganda (22.1%) [
25]. The practice of CCU could be due to societal perception of women using contraceptive as being promiscuous [
9,
12,
29,
32], patriarchy [
5,
32], fear of intimate partner violence [
11,
42,
43], disagreement on the number of children [
32], religious beliefs [
12] and limited male involvement [
9,
44]. CCU could reflect women empowerment and autonomy in decision making [
43] but also indicate male dominance in decision making and create a barrier to increasing contraceptive coverage [
5]. The increased prevalence of CCU highlights the need for targeted interventions to improve spousal involvement in their partners’ reproductive health choices especially among the uneducated, poorest, and rural women, which will ultimately increase FP uptake and address the unmet need for FP.
Similar to previous studies in Ethiopia [
28], Ghana [
29], Kenya [
1,
24] and Nigeria [
4], injectables and implants were the commonest methods of contraceptives used overtly and covertly by married women. Injectables and implants are easy-to-use and effective [
43] modern reversible contraceptives lasting 3 months, and three or 5 years, respectively [
3]. Injectables are widely available and accessible in most health facilities and pharmacies, and are concealable [
32] and do not require male cooperation hence promote CCU [
43]. This finding highlights the need for continued support for partner involvement in FP use to promote open FP use and to ensure married women can use contraceptives that are suitable for them and not just the concealable ones. Also, a consistent availability of FP commodities in all healthcare facilities and training of health professionals to provide support to clients could help improve FP use in general.
Girls’ education delays early marriages, reduces the age at sexual debut and improves girls’ and women’s self-esteem [
45], which is likely to improve communication with their partners. This could explain the observed lower odds of CCU with an increase in age at sexual debut. Women who delay their sexual debut could have a reduced need for contraceptives but also a high likelihood to use contraceptives with their partner’s knowledge. Married women with children are more likely to be involved in decision making about the desired number of children and birth spacing [
25,
46] hence the lower odds of CCU among women with two or more children compared to those with none. This is consistent with a study in Ghana where women with no children were more likely to use contraceptives covertly compared to those with children [
29].
We also found that women in rural areas were more likely to practice CCU compared to those in urban areas, though not statistically significant. Married urban women may be more involved in decision making on children and FP due to their high level of knowledge on contraceptive and gender-equitable attitude [
23]. On the contrary, our study found that women from the rural counties of Kitui, Nyamira, West Pokot, Kilifi, Bungoma and Nandi were less likely to use contraceptives covertly compared to women in urban cosmopolitan Nairobi County. The reason for this is not clear but it may be due to perceived male dominance, reduced women autonomy cultural practices that may hinder FP uptake in general.
Our study is one of the first to explore the practice of CCU in Kenya. We used the most recent nationally representative cross-sectional data from 11 out of the 47 counties of Kenya, which makes our findings generalizable to the country. The major strength of this study is that it focuses on women-in-a-union and excludes women not-in-a-union who we could not ascertain whether they had partners. Our study findings are, therefore, important for informing immediate FP policies and interventions that focus on married couples. However, based on the cross-sectional nature of the data we could not infer causation. Also, some key determinants of CCU such as duration of the marriage, years of schooling, decision making and exposure to FP messages in the media were not collected. Regardless, our findings are comparable to those of similar settings and provide the most recent preliminary evidence on the extent and factors associated with CCU in Kenya.
