Mobile Phone Based Strategies for Preconception Education in Rural Africa.

BACKGROUND: Prepregnancy health care is vital to alleviate and prevent maternal and neonatal disability and death.
OBJECTIVE: The purpose of the study was to measure the levels of knowledge and attitude on preconception care and their determinants among women who delivered at government hospitals in a rural setting in southern Ethiopia.
METHOD: A facility-based cross sectional study was done from January 01 to February 30, 2017 on a sample of 370 women who delivered at government hospitals in Wolayita zone. The mothers were selected using systematic random sampling technique. The data were collected using structured and pretested interviewer administered questionnaires at the postnatal ward of each hospital. Data were analyzed using bivariate and multivariable techniques.
RESULTS: The result showed that 53% (95% confidence interval [CI]: 47.8%, 58.1%) of mothers who delivered at public hospitals had adequate level of knowledge on preconception care, whereas 54.3% (95% CI: 49.2%, 59.5%) possessed positive attitude to preconception care. Mothers who have radio, planned pregnancy and have participated in community meetings related to preconception care had a meaningfully higher odds of good level of knowledge to preconception care. Ordinal regression showed that women who own mobile phone had at least three times significantly higher odds of positive attitude to preconception care, whereas women who have participated community meetings had lower odds of positive attitude on preconception care.
CONCLUSION: The results revealed that the levels of mothers' knowledge and positive attitude on preconception care are low relative to other studies. Using transistor radio and mobile phone have significant effect in improving the knowledge and attitude of reproductive age women on preconception care. Hence, providing community health education based on radio and/or mobile phone messaging could be useful in positively influencing the knowledge and attitude of women on preconception care.

Background

Preconception health care is a set of prepregnancy interventions to reduce the influence of biomedical, behavioral and social risks of mothers’ health, and unborn child health [1]. It can improve maternal and neonatal outcome by identifying, modifying bad habits and behaviors before conception and decreasing unintended pregnancies [2]. Besides, most of pregnancy and childbirth complications can be alleviated by implementation of preconception care at health institution, meanwhile in low resource settings preconception care is not regularly implemented [3].

Though both governments and civil societies in developing counties frontline agenda is maternal and neonatal health service, newborn and child death and stillbirth, of which 77% are preventable by creating platform for essential packages at community, health center and hospital levels have not yet been reduced to the expected level [4].

Worldwide, 216 maternal deaths occurred per 100,000 live births in 2015, of which 99% occurred in resource-constrained areas, especially south Asia and sub-Saharan Africa. The most substantial cause of mortality in women are: obstetric hemorrhage, preexisting medical conditions, hypertensive disease of pregnancy, infections/sepsis, unsafe abortion, and other indirect causes [4]. Globally, 2.6 million children died in the first month of life and neonatal mortality was estimated at 19 deaths per 1,000 live births [5]. The under-five mortality rate in 2015 was 42.5 per 1,000 live births [67]. In Ethiopia the maternal mortality rate is estimated at 412 per 100,000 live births in 2016, neonatal mortality at 29 deaths per 1000 live births, infant mortality at 48 deaths per 1,000 live births and the under-five mortality rate is estimated at 67 per 1000 live birth in 2016 [8].

Reproductive planning through preconception care could reduce 71% of unwanted pregnancies, thereby eliminating 22 million unplanned births, 25 million induced abortions and 7 million miscarriages [910]. Similarly, lack of preconception care and low folic acid supplementation for women in developing countries might increase the risk of neural tube defect in newborns by four times, compared with developed countries [11].

The basic concept of preconception care is to advise women of childbearing age away from any negative health behaviors or conditions that might affect a future pregnancy [12]. “A reproductive health plan reflects a person’s intentions regarding the number and timing of pregnancies in the context of their personal values and life goals.” This health plan will increase the number of planned pregnancies and encouraged persons to address risk behaviors before conception, reducing the risk of adverse outcomes for both the mother and unborn child [1314].

A study done in Kelantan, Malaysia found that 51.9% of women attending maternal health clinic had good level of knowledge on preconception care and 98.5% had positive attitude regarding preconception care [15]. A study done in Egypt revealed that 39.2% of pregnant women attending ANC at Ain Shams University Hospital knew about the role of folic acid supplementation in prevention of congenital anomalies [16]. A community-based study done in Ethiopia revealed that 27.5% of reproductive age women had good level of knowledge regarding preconception care [17].

Studies suggested antenatal care ought to initiate before pregnancy to improve pregnancy outcome. Implementation of preconception care in maternity care unit is crucial to achieve the sustainable development goal (SDG) targets in relation to maternal, neonatal and child health, by decision makers and stakeholders. However, evidence on the levels of knowledge and attitude toward preconception care amongst women in rural African settings is scarce. The purpose of the study was therefore to measure the levels of knowledge and attitude on preconception care and their determinants among women who delivered at government hospitals in a rural setting in southern Ethiopia.

Methods

Study design and setting

A hospital-based cross-sectional study was done from January 1 to February 30, 2017, among mothers who delivered in public hospitals in Wolayita Zone and who were on immediate postnatal ward. Wolayita zone is found in the Southern Nations, Nationalities and Peoples Regional State of Ethiopia. According to the 2007 census of Ethiopia, the total population of the zone was 1.7 million. The public health institutions found in the zone were one referral hospital, four district hospitals and 70 health centers (5 urban and 65 rural). The total number of births from the five hospitals in 2016 was 7445 (Otona Hospital 3511, Bonbe hospital 1228, Halale hospital 1142, Bitana Hospital 956, and Bale Hospital 608).

Study population and sampling procedures

Study populations were women who delivered at government hospitals in the Wolayita zone during the study period. Mothers who had loss of consciousness, had mental problem, and were referred to other hospitals were excluded.

Sample size was determined using the software Epi Info version 7 with the following assumptions: 95% confidence interval, an anticipated proportion of knowledge of preconception care of 10.4% based on a study in Nigeria [18], 4% of margin of error and a design effect of 1.5. The calculated sample size was 336. Combined with the 10% non-response rate, total sample was 374.

All public hospitals in the Wolayita zone were included in the study, and the sample size was proportionally allocated into five public hospitals based on number of deliveries each hospital. Systematic random sampling procedure was used to select study participants in each hospital. Monthly expected number of deliveries at public hospitals in Wolayita zone was 620; thus the sampling interval used was 2.

The questionnaires were prepared by reviewing the existing literatures. The questionnaire was prepared in English and then translated to Wolaytigna, and back to English to check uniformity. The questionnaire consisted of 57 items: 13 sociodemographic items, 6 obstetric items, 4 source of information items, 23 knowledge variables, and 11 attitude items. For attitude items, the Likert scale was used (1-strongly disagree, 2-disagree, 3-neutral, 4-agree and 5-strongly agree). During analysis, the Likert scale items were categorized into three response categories to compute women’s attitude on preconception care: disagree (by merging 1-strongly disagree and 2-disagree), neutral and agree (by merging 4-agree and 5-strongly agree).

In Hawassa University Comprehensive Specialized Hospital, a pretest was carried out with 5% of study participants. Based on the pretest findings, amendment was done before initiation of actual data collection.

Data were collected using structured and pretested interviewer administered questionnaire through face-to-face by 10 midwives who had received training on basic emergency obstetrics and newborn care (BEmONC) and who can fluently communicate in the local language (Wolaytigna). Training was given to data collectors for three days on data collection methodology and related issues prior to the start of data collection time and were closely supervised during the data collection period.

Statistical analysis

Data entry was done EPI Data 3.1 and transferred to SPSS version 20.0 for analysis. Based on 23 knowledge items, we computed an overall knowledge score for each study participant. Those who had knowledge score above the mean knowledge score were level as “adequate knowledge” whereas at or below the mean knowledge score were categorized as “inadequate knowledge”. Eleven attitude items were recorded into disagree, neutral and agree. Those whose response was “agree” were considered as having “positive attitude” towards preconception care, whereas those whose response was “disagree” were regarded as having “negative attitude” towards preconception care; those with a “neutral” response were considered as having “neither negative nor positive attitude”. Descriptive analysis was done to calculate and describe the basic characteristics of the study participants knowledge and attitude to preconception care. Binary logistic regression was used to identify the correlates of knowledge on preconception care, while ordinal regression was used to identify correlates of attitude towards preconception care. Adjusted odds ratios (AORs) with 95% confidence intervals (CIs) were used to judge the presence and strength of association between dependent and independent variables. A P value of <0.05 was taken as statistically significant.

Obstetric characteristics of study participants

In 296 (80%) of the mothers, the recent pregnancy was planned. Nearly two-thirds (65.1%) of mothers had used family planning before the current pregnancy. Ninety-eight (26.5%) of the mothers were primigravidae and 272(73.5%) were multigravidae, whereas 110 (29.7%) were primipara and 260 (70.3%) were multipara. Two hundred eighty-three (76.5%) of the participants had antenatal contact for this pregnancy, of whom 152 (41.1%) had four or more ANC contacts (Table 2).

Women’s attitude regarding preconception care

Among the total of 370 respondents, 300 (81.1%) of the mothers agreed that a hospital setting is the best place to provide preconception care and 277 (74.9%) of women also agreed that preconception care is an important health issue for women of childbearing age. However, 54 (14.6%) of women agreed that there is not enough time to plan to get preconception care. Overall, 201 (54.3%) (95% CI: 49.2%, 59.5%) of mothers had positive attitudes towards preconception care, 23 (6.2%) (95% CI: 4.1%, 8.9%) of mothers had neither positive nor negative (neutral) attitudes towards preconception care and 146 (39.5%) (95% CI: 34.6%, 44.6%) of mothers had negative attitudes towards preconception care (Table 4).

Discussion

Findings revealed that level of knowledge of preconception care amongst women who delivered at government hospitals in the Wolayita zone is 53%. This finding is inconsistent with the findings in Northwest Ethiopia (27.5%) [17], Sudan (11.1%) [19], Nigeria (2.5%) [9], Iran (10.4%) [20], Saudi Arabia (37.9%) [21], United Arab Emirates (46.4%) [22], and Turkey (46.3%) [23]. The possible explanation for higher level of knowledge in the present study could be the time of study, maternal health is given high attention which may result in an overall increase in knowledge of issues related to maternal health. Contextual differences in the study settings could also account for the observed differences.

On the other hand, it is consistent with studies done in Malaysia (51.9%) [15], and in Qatar (53.7%) [24]. However, this fining is lower than the study done in Canada (70%) [25], Jordan (85%) [26], British Colombia (71%) [27], Saudi Arabia (84.6%) [28], and in the United States of America (76%) [29]. The possible explanation could be low level of knowledge due to health sector infrastructure difference, socioeconomic difference, lack of health wellness clinic in the area of the present study, lack of preconception service across Ethiopia, lack of promotion of preconception care by mass media, and low commitment of health care providers due to high load of clients.

In this study the correlates of knowledge of preconception care were found to be possession of transistor radio, planned pregnancy, and having participated in community meetings related to preconception care. Women who had a radio had were three times more likely to have adequate knowledge of preconception care. This is inconsistent with studies done in Ethiopia and Nigeria [917]. The higher level of knowledge of preconception care amongst women who possess a transistor radio and who participate in community meetings related to preconception care can be due to exposure of such mothers to health information via radio and also during community meetings. The community meetings could also create a platform for women to share their positive and negative childbirth experiences and prevention mechanisms. Similarly, women who planned the recent pregnancy were six times more likely to have adequate knowledge of preconception care, which coincides with the findings in Brazil [30]. The possible explanation could be reproductive age women who planned pregnancy are expected to know their healthiness correlated to maternal health care and may thus have also a better awareness of issues correlated to preconception care.

In this study 54.3% of mothers were found to have positive attitude towards preconception care. This finding is incomparable with studies done Malaysia (98.5%) [15] and USA (98%) [29]. The difference might be due availability and accessibility of the service in settings with better socioeconomic status such as in Kelantan, Malaysia and USA.

Women who possess mobile cell phones are more than twice as likely to have positive attitudes towards preconception care; however, women who have participated in community meetings related to preconception care had decreased odds of positive attitudes towards preconception care. The reason women who possess cell phone have higher odds of positive attitudes towards preconception care could be due to better exposure of such women to health information via frequency modulated (FM) radio services, which are available in most cell phones and for some of the literate mothers via mobile internet. Women who posses mobile phones may also generally be in a better socioeconomic position and hence may have more positive attitudes to health care services. The reason women who participate in community meetings have decreased odds of positive attitudes is difficult to explain, but this could be a result of being fed up with regular participation in community meetings.

The strength of this study relative to previous studies is incorporating relevant variables that were not addressed previously, such as having planned pregnancy, possession of transistor radio and participating in community meetings related to preconception care. The limitation of this study is that it did not incorporate both sides, such as partners of women. Outcomes can be, to some degree, affected by recall and social desirability biases.

Conclusion

Levels of women’s knowledge and positive attitude of preconception care among women who delivered at government hospitals in rural southern Ethiopia is low compared with other studies. Using a transistor radio and mobile phone have significant effects in improving the knowledge and attitude of reproductive age women on preconception care. Hence, providing community health education based on radio and/or mobile phone messaging could be useful in positively influencing the knowledge and attitude of women on preconception care.
