Background

The long-acting reversible contraceptive (LARC) is a highly effective modern contraceptive method that includes an intrauterine contraceptive device (IUCD) and implants, which prevent unintended and closely spaced pregnancy [1]. Extended postpartum period LARC use refers to the initiation of IUCD or implants during the first 12 months of childbirth.

Globally, about 80 million unintended pregnancies occur during the postpartum period due to lower use of family planning [2]. In sub-Saharan African countries, 40% of unmet needs for family planning occur during the postpartum period [3]. The postpartum women LARC use has universally recognized several health benefits. LARC use reduces maternal and neonatal mortality and morbidity by preventing unintended pregnancy and unsafe abortion [4]. An individual couple delaying their next child at least 2 years and above can avert 30% of maternal and 10% of child mortality [5]. Published reports showed that a birth-to-pregnancy interval of above 2 years reduced prematurity, low birth weight, as well as small for gestational age [6]. In addition to health, FP has economic and social benefits for women, families, and the population at large. Family planning slowing the population growth, which aids the women to possess good income potential, dedicates enough for each child, resulting in reductions in poverty [7, 8].

Currently, family planning (FP) services incorporate into maternal and child health care services at all levels of the health care delivery system in Ethiopia. The government, local, and international partners on the FP program conducting maximal efforts to reach all over the country. The health extension workers intensively deliver the FP service to rural communities at health posts. [9]. Despite the above effort done, the Ethiopian demographic health survey (EDHS) 2016 reported only 7.1% of women utilized LARC, which was far from the global FP target 2030 [10]. A cross-sectional study in Hossana (36.5%) and Durame town (36.7%) of women were using long-acting reversible contraceptives during the extended postpartum period, which was higher than the national magnitude [11, 12].

Many previous studies identified factors influencing the poor uptake of the long-acting reversible modern postpartum contraceptive use in Ethiopia. Socio-demographic factors like age, level of education, marital status, and religion significantly affect LARC use [11, 12]. Antenatal and postnatal Family Planning counseling, menses return, resumption of sexual intercourse, and other maternal and reproductive health-related factors influence LARC utilization [13, 14].

Even though many studies were conducted to assess modern contraceptive use, there is a scarcity of evidence about factors affecting long-acting reversible contraceptive use during the extended postpartum period at the community level in southern Ethiopia. Therefore, this study aimed to assess the use of long-acting reversible contraceptives and associated factors among women who gave birth in the last 12 months in Arba Minch town, Southern Ethiopia.

Methods

We conducted a community-based cross-sectional study design from October 1st to November 30th, 2019 in Arba Minch town. Arba Minch is the capital of the Gamo zone, southern nation nationalities peoples region, Ethiopia. Arba Minch Zuria woredas in the north, west, and south and Nech-Sar National park in the east and some part of the northeast are the border of the town. The total area of the town is 4011hactare structured with 11 kebeles. Arba Minch town has a population of 112,724, of which 56,137 (49.8%) are males and 56,587 (50.2%) are females. There is one General Hospital, three public health centers, and 11 health posts.

The source population of this study was all mothers who gave birth for the last 12 months before the study. The study population included sampled mothers who gave birth in the last 12 months before this study. The single population proportion formula was used to calculate the sample size. The assumption of 95% confidence level, 5% margin of error and prevalence of Long-acting reversible contraception use which is 36.7% (Durme town [15]) were considered. After adding a 20% non-response rate, the final computed sample size was 429.

We identified all households who have a mother with a history of birth in the previous year using the family folder of the Health extension. The proportional number of study participants was allocated for each kebele. A lottery method was used to select the first postpartum woman. Then, the next postpartum woman was selected through a systematic random sampling of every Kth (3rd) interval household. In a case when the study participants could not interview, we attempted two times to interview the respondent, then we asked the next study participant. We used the lottery method when over one mother who gave birth in the last 12 months was found in the same house.

Data collection instrument and procedure

The data was collected by using a pre-tested structured questionnaire adapted from different literature, which was developed for similar purposes by different authors. The data collection tool (questionnaire) was prepared first in English and then translated to Amharic, which was translated back to English to ensure consistency. We used the Amharic version of data collection. The questionnaire comprises socioeconomic and demographic characteristics, reproductive history and maternal health care, knowledge, and current practice of long-acting reversible contraceptives during the extended postpartum period.

Two diploma midwives and two clinical nurses collected data. One BSc midwife supervisor the interview. We trained the interviewers for one day before the actual data collection. Lecturing, mock interviews, and actual field practice were used to train the data collectors. The interview was done under close supervision. Interviewer-administered questionnaires via face-to-face interviews were used for data collection.

Data processing and analysis

All filed questioners were cheeked for completeness, consistency, and accuracy. The data was entered into Epi-Data version 4.6 and exported to the statical package of social science (SPSS) version 25 for further analysis.

Descriptive analyses (frequency, mean, percentage) were carried out for the variables. A Binary logistic regression was used to determine the relationship between the outcome and each independent variable. Those variables having a P-value of 0.25 and less in the bivariate analysis were added in the multivariable logistic regression analysis. Hosmer-Lemeshow goodness of fit test was used to check the fitness of the model, which did not have a statically significant p-value of 0.183. The adjusted odds ratio along with 95% of confidence interval was an estimate to identify factors associated with the outcome variable. The level of statistical significance was declared at a p-value less than 0.05. The results are finally presented in tables, graphs, and text.

Result

Socio-demographic characteristics of the respondent

A total of 416 postpartum women participated with a response rate of 96.96%. The age of women ranges from 17 to 45, with a mean age of 28.2 (SD ±4. 951) years. Three hundred ninety-two women (94.2%) were married (Table 1).

Male partner involvement related factors of the study population

Two hundred eighty-five postpartum women discuss with their partner. On the other hand, 68% of postpartum are supported by their partner to use the modern contraceptive.

Knowledge and media exposure about contraceptive

Knowledge of at least one modern contraceptive is 98.1%. About the attitudes of the respondents towards the benefits of modern contraceptive utilization about half (50.7%) of them had positive attitudes. One hundred eighty-three (44.0%) postpartum women had got information from the media.

Long-acting reversible contraceptive use in the extended postpartum period

The prevalence of long-acting contraceptive utilization was found to be 94 (22.6%). Seventy-seven respondent used (82%) followed by IUCD 17(18%) (Fig. 1).

Factors associated with postpartum long-acting reversible contraceptive utilization

In the multivariable logistic regression analysis, women’s age, being married, menses resumption, sexual intercourse resumption, and got family planning counseling showed a significant association with postpartum LARC use.

Maternal age ≤ 24 years (AOR = 3.7, 95% CI: 1.5, 8.9), being married (AOR = 3.5(1.17–10.28)) menses resumption (AOR = 4.9 95% CI: (2.92, 8.20)), sexual intercourse resumption (AOR = 7.1 95% CI: (4.03, 12.56)) times more likely to use postpartuim LARC compered to their counterpart.

The study also indicated that postpartum women who were counseled about postpartum family planning were 3.2 times more likely to use LARC than those who did not counsel [AOR = 3.2 95% (1.95, 5.28)] (Table 4).

Discussion

This community-based research aimed to identify long-acting reversible contraceptives use and associated factors in Arba Minch town among women in the extended postpartum period. The overall prevalence of long-acting reversible contraceptive use was 22.5% during the extended postpartum period. This finding was higher than the national figure(7.1%) [16]. This may be justified by increased access to and inclusive sexual reproductive health services for the past 4 years.

The finding from Hosanna (36.5%) and Durame (36.7%) town were higher than this study [15, 17]. The reason for this difference might be due to the sample size, the residence of study participants, and access to information about family planning.

This study showed that postpartum women age less than 24 years were 3.7 times more likely to use LARC compared with women age 35 years and more. This finding is also supported by the study in Gondar Town, North West Ethiopia [18]. The possible reason may due to young women are more sexually active than older women.

This study also indicated that postpartum married women were three and half times more likely to use long-acting reversible contraceptives than others. This is consistent with the study done at Debre Tabor and Addis Ababa [19, 20]. This might be due to that married women were living with their husbands. They might start regular sexual intercourse earlier than the non-married couples that may force to use contraceptives to program the birth of the next child.

Family planning counseling during ANC and PNC was found to be associated with long-acting reversible contraceptive use during the extended postpartum period. Women who had received postpartum family planning counseling during ANC and PNC were 3.2 times more likely to use long-acting reversible contraceptives in the extended postpartum period than their counterparts. This result is agreed with Axum, north Ethiopia, and Malawi [12, 21]. This may be because women who have received family planning counseling during ANC and PNC might be highly motivated for LARC use.

Mothers whose menses resumed were almost five times more likely to utilize long-acting reversible contraceptives. This is inconsistent with the kinds of literature done in Addis Ababa and Gondar [18, 20]. This is because postpartum women may be aware of their fertility returning when menses return. This could be due to postpartum women believed that a return of fertility only occurs along with the return of menses.

The other stronger factor for the need for family planning is the resumption of sexual intercourse. Women who have resumed sexual intercourse were almost seven times more likely to use LARC compared to counterparts. This finding is supported by a study done by Hosanna and Axum [11, 12]. This might be because women who resumed sexual activity have a fear of getting pregnant. Consequently; they seek contraception than those who had not resumed sex.

Conclusion and recommendations

The finding of this showed that the level of long-acting reversible contraceptive utilization in the extended postpartum period was low. Women’s age, being married, menses resumption, resumption of sexual intercourse, and family planning counseling during ANC and PNC were significant factors associated with the long-acting reversible contraceptive use. Therefore, health institutions should strengthen antenatal and postnatal counseling of postpartum family planning. Health workers also should provide advice and counseling for postpartum women that make them understand that fertility may precede the return of menses.
