This study aimed to identify the factors associated with the unmet need for FP among MWRA. The prevalence of unmet need for FP was 38%, which is higher than the national figure (24%) [3]. The probable reasons for the higher unmet need in this study might be due to the study setting with easy access to abortion services [29] and a significant proportion of husbands being away from home. A consistent result (38%) was found in another study of Nepal [9]. The proportion was higher (49%) in a study conducted among women from disadvantaged caste/ethnicity [8]. Similarly, a higher proportion (48%) of women had unmet needs in a study of a rural hilly area of Nepal [11], whereas it was 31% in Debre Berhan Town, Amhara of Ethiopia [30].
Among several reasons for nonuse of contraceptives, the most common ones are fear of side effects and health concerns, husband and family opposition, perceived low risk of pregnancy due to breastfeeding/not menstruating after birth/infrequent sex, and inconvenience in using contraceptives [8, 10, 27, 31–35]. Limited knowledge of contraceptive methods and reproduction is one of the major reasons for nonuse of contraception [36].
The current study showed that the husband’s occupation, spousal discussion on FP, and number of living children are statistically associated with unmet need for FP. In this study, respondents whose husbands were involved in foreign employment were more likely [aOR: 4.408; CI: 2.068–9.399] to have an unmet need for FP than those employed within the country. In Nepal, at least one member of approximately one-third of households, with the majority of them husbands, migrates for employment. Among them, nearly 85% go to other countries[37]. Temporary work-related migration is increasing in Nepal. In the 2009 survey, 64% of spousal separation cases were for three or more months. Among these, 37% were in India and 54% were in other countries [38].
A qualitative study in rural areas of far western Nepal found almost every young male Dalit migrating to India yearly, most of them after crop harvesting and returning during the rice planting season[39]. Couples living separately also need to use contraceptives whenever husbands visit home[38]. A national-level survey of Nepal found that women whose husbands live away from home have a higher unmet need for FP, as they are less likely to use contraceptives than those living with husbands [40]. Consistently, a study from the Nepal Demographic and Health Survey 2016 showed that spousal separation was associated with a higher unmet need for contraceptive use (aOR: 8.00; p < 0.001) [41]. Less time to prepare about FP on the husband’s arrival and the communication gap between spouses might have influenced the lower use of contraceptives among migrants [42]. It is difficult for women to make decisions alone about using FP methods as well as accessing contraceptives. Furthermore, using contraceptives while husbands are away might be challenging to women due to fear of being considered unfaithful by the community and husband [42]. However, we were unable to assess the sexual activity of women in this study due to privacy reasons.
Furthermore, the findings of this study indicated a higher likelihood [aOR: 3.212; CI: 1.368–8.135] of having an unmet need for FP among couples who did not discuss using the FP method compared to those who discussed it three or more times. Likewise, a study found that spousal communication about FP increased contraceptive use in a rural area of Nepal [43]. Similarly, another study of Nepal also concluded that those who communicated with their spouse had a higher likelihood of making decisions jointly and using the FP method [20]. Consistent results were found in studies conducted in Botswana [25], Cameroon [27] and Ethiopia [44], and couples who discussed FP were more likely to have lower unmet needs.
Only a small proportion of women become involved in decision making with regard to reproductive preference [36, 45]. Husbands are usually the decision makers for the number of children and use of FP methods [36]. Males being decision-makers in most households are supposed to start discussion on FP[45]. Even discussion on FP is not perceived as important by many couples[45].
Similarly, the study showed that women with three or more children were more likely to have a higher unmet need for FP [aOR: 8.758; CI: 1.691–45.355] than women with no child. This is consistent with the findings of studies conducted in Nepal [9, 12], Ethiopia [46] and Burundi [47]. The unmet need for FP is greater among women with a higher number of living children[9, 35, 47]. Women do not use the FP method even after they find their family size complete[48]. Many women resort to induced abortion rather than using contraception mainly due to fear of side effects[48, 49]. Consistently, in Sub-Saharan Africa, women chose abortion as a method of limiting family size instead of using contraceptives, especially in places where abortion services were accessible [29].
Fear of side effects and health concerns among women is the major reason for not using contraceptives in Nepal and elsewhere [8, 10, 27, 35, 49]. Most of the nonusers reporting fear of side effects have already used contraceptives and discontinued them [31].
Strengths and limitations
The study has some strengths as well as limitations. It has underlined the factors associated with the unmet need for FP and the reasons behind not using FP methods. Data collection was performed by the first and third authors themselves using a pretested questionnaire prepared in the understandable Nepali language. With regard to limitations of the study, due to resource and time constraints, the study was limited to only one ward, and the findings may not be generalizable in all places of Nepal. However, the findings might reflect the situation of an unmet need for FP in other similar semiurban settings. Being a quantitative study, the information might be limited. Being a small-scale study, we could not explore whether the unmet need is for spacing or limiting. Similarly, we only relied on a small sample size in a ward of the municipality of semiurban areas. Furthermore, due to privacy reasons, we could not explore the sexual activities of migrants’ wives. Therefore, a more comprehensive study exploring more qualitative information is needed.
