Prevalence and determinants of acute diarrhea among children younger than five years old in Jabithennan District, Northwest Ethiopia, 2014
BMC Public Health volume 17, Article number: 99 (2017)
Despite the global decline in death rates of children younger than five years old, the risk of a child dying before turning five years of age remains highest in the WHO African Region. The problem of child death in Ethiopia is worse, with an Ethiopian child being 30 times more likely to die by his/her fifth birthday than a child in Western Europe. Therefore, the aim of this study was to assess the prevalence and factors associated with diarrhea among children younger than five years old.
A community-based, cross-sectional study was conducted with mothers who had children younger than five years old from April to June 2014. A multistage sampling procedure was used to select eligible women. The data were coded, entered, cleaned and analyzed with the SPSS software package, version 16.
he data of 775 mothers were included in the analysis, and 21.5% of the children had diarrhea in the two weeks before the survey. The main factors affecting the occurrence of diarrhea were residence (Odds ratio (AOR) = 11.29, 95% Confidence interval (CI): 3.49-36.52), sex (AOR = 2.52, 95% CI:1.28-4.93), methods of complementary feeding (AOR = 50.88, 95% CI: 23.85- 108.54), types of water storage equipment (AOR = 19.50, 95% CI: 8.11-46.90), and cleansing materials used to wash hands (AOR = 5.53, 95% CI: 2.19-13.99).
Approximately one-fifth of the children included in the study reported diarrheal disease. Residence, sex of the child, type of water storage container, methods of complementary feeding, and cleansing materials to wash the hands were the most important variables that affected the occurrence of diarrhea in children. Therefore, families, the government and nongovernmental organizations working in the area must cooperate in interventions and prevention to minimize the risk of disease.
Despite the global decline in the death rates of children younger than 5 years old, the risk of a child dying before becoming 5 years of age remains highest in the WHO African Region (90 per 1000 live births), which is approximately seven times higher than that in the WHO European Region (12 per 1000 live births) .
Children in developing countries are disproportionately affected by preventable and treatable diseases with simple and affordable interventions. Consequently, children in these countries are 10 times more likely to die before the age of 5 years old than children in industrialized countries [2, 3].
People in the economically poorest regions of the world and the least developed countries continue to bear the heaviest burden of child deaths. More than four-fifths of all deaths among children younger than 5 years old in 2011 occurred in sub-Saharan Africa and South Asia . The problem in Ethiopia is even worse than elsewhere in the world, with an Ethiopian child being 30 times more likely to die by his/her fifth birthday than a child in Western Europe .
Diarrheal diseases account for 1 in 9 child deaths worldwide, making diarrhea the second leading cause of death among children younger than the age of five . The disease is preventable and is characterized by the passage of loose or watery stools three or more times over a 24-h period .
Diarrhea is responsible for 17% of all deaths (approximately 2.5 million deaths each year) among children younger than 5 years old worldwide; this rate is higher than that of AIDS, malaria, and measles combined. The majority (42%) of these deaths are concentrated in the Sub-Saharan African countries, including Ethiopia (88 per 1000 live births) .
Recent national estimates have indicated that the two-week prevalence of diarrhea in children was approximately 13% . Moreover, few local studies have reported that the magnitude of diarrhea among children younger than 5 years old in different regions of the country ranges from 18 to 31% [9–12]. Although this evidence is available, there has still been a lack of studies in the country to obtain up-to-date information on the disease and to prioritize interventions by decision makers to overcome the problem. Therefore, the aim of this study was to identify the magnitude and to determine the factors that affect diarrheal disease among children younger than five years old.
A community-based, cross-sectional study was conducted among mothers with children younger than 5 years old from April to June 2014in Jabitehnan District, West Gojjam Zone, Amhara Region, Ethiopia. This District is located 390 kilometers northwest of Addis Ababa; it has 37 rural and 2 urban kebeles.
According to a 2014 Amhara Bureau of Finance and Economic Development office report, the total population of the District was estimated to be 207,162. The number of childbearing women (15-49 years old) was 45,938, and the estimated number of children younger than 5 years old in the district was 27,759.
The eligibility criteria
Mothers who had children younger than 5 years old living in the selected kebeles of the District in the last 6 months of the survey.
Sample size determination of the study
The sample size of the study was determined using a single population proportion formula, considering an estimate of 18% expected prevalence of diarrhea among children younger than 5 years old . Assuming any particular outcome to be within a 4% marginal error and a 95% confidence interval of certainty, the final sample size with a design effect of 2 and a 10% non response rate was determined to be 781 mothers of children younger than 5 years old.
A multistage sampling technique was used to select the study participants. Initially, the study area was divided into two strata: urban and rural kebeles. One urban and seven rural kebeles were selected by a simple random sampling technique. The calculated sample size was allocated into randomly selected kebeles in the district, proportional to the size of the population. The allocated sample size in each kebele was divided by the number of households in the kebele with children younger than five years old to obtain a sampling fraction. Then, a systematic sampling technique was employed to obtain the respondents to the study. In cases in which more than one mother with children younger than 5 years old was found in the household, a simple random sampling method was employed to select the mother to be included, and in cases of more than one children younger than 5 years old of one mother in the household, the eldest child was studied (Fig. 1 shows the schematic presentation of smapleling procedure).
Age of mother, educational status of mother, family size, residential area, sex of child, age of child, number of children younger than 5 years old in the family, etc.
Latrine availability, hand washing facility, source of water, etc.
Latrine utilization, hand washing practices, exclusive breastfeeding, complementary feeding practices of children, etc.
Data collection and analysis
The data were collected using a face-to-face administrated questionnaire and an observation checklist; the questionnaire was adapted from reviewed articles [9, 11, 14] (Additional file 1). The data were collected by six diploma nurses who had experience in data collection in the rural community
Two days of training were provided to maintain the quality of the data and ethical issues. A pre-test was performed in kebeles not included in the main survey, and the necessary corrections were performed to the tool before the data collection was undertaken. The collected data were checked for errors and incompleteness on a daily basis. Finally, the data were coded, entered and analyzed using SPSS software, version 16 (Chicago, IL, USA).
Descriptive statistics were used to determine the magnitudes of events in the study. Bivariate logistic regression analysis was computed to test whether there were associations between diarrheal disease and selected predictor variables.
Factors associated with an outcome variable in bivariate analysis at a significance level of 0.20 were identified and exported to multivariable logistic regression analysis, and the model was built with backward elimination. Regarding the effect of multi collinearity, intra-predictor variables were tested using the standard errors of the beta coefficients. The assumptions of logistic regression analysis were assessed using the Hosmer-Lemeshow model fitness test.
Finally, 95% confidence intervals not including one, with their corresponding P-values less than 0.05, were considered statistically significant.
Diarrheal Disease (the outcome of the study)
The occurrence of loose or watery diarrhea at least three times per day for the previous 2 weeks.
Hand washing at critical times
Washing the hands before and after cooking foods, after latrine use, and before feeding the child.
Proper hand washing
Hand washing with soap or ash at critical times.
The lowest governmental administrative unit in the hierarchy.
Socio-demographic characteristics of the study participants
The data of 775 mothers of children younger than five years old were included in the analysis of the intended sample size of 781 mothers, resulting a response rate of 99.2%. Five hundred sixty- nine (73.4%) mothers were in the age range of 20-34 years old, and the mean age of the respondents was 30.04 years old, with a standard deviation of 5.19 years.
Four hundred two (51.9%) of the children younger than 5 years old were female, and regarding religious affiliation and the residences of the respondents, 766 (98.8%) were Orthodox Christians, and 708 (91.4%) were from rural kebeles.
Concerning the number of children younger than 5 years old in the sampled households, 637 (82.2%) of them reported having one child, whereas the remainder, 138 (17.8%) households, had two children.
Seven hundred fifty-two (97%) of the respondents were married, and 501 (64.6%) of the households had a family size less than five members. Regarding the occupation and educational status of the husbands of the study participants, 737 (95.1%) engaged in farming, and 87 (11.7%) attended primary school (see Table 1).
Environmental characteristics of the respondents
According to the findings of this study, approximately one-fifth of the households were drinking water from unprotected sources. Regarding the required time spent to obtain drinking water,192 (24.8%) and 173 (22.3%) of households had spent 15 to 30 and more than 30 min walking distances to fetch water, respectively. Four hundred twenty-eight (55.2%) of the households used a jerry can (narrow-neck water container) to store drinking water.
Seven hundred thirty-four (94.7%) of the households had a latrine, and 725 (98.8%) of the latrines were traditional pit latrines.
More than 30% of the latrines in the district did not have a hand washing facility. According to this study, 216 (29.4%) of the latrines had feces around their holes. In addition, there were observable feces in the compounds of 98 (12.6%) households included in the study. This study also showed that 194 (25%) of the households shared the same house with domestic animals. Regarding the waste disposal methods of the households, 308 (39.7%) and 207 (34.8%) did not have proper solid and liquid waste disposal systems, respectively (see Table 2).
Prevalence of diarrheal disease and behavioral and child care practices
Regarding the time when breastfeeding started after childbirth, 190 (24.5%) of the children had received breast milk after one hour, and approximately one in five children of the respondent mothers were not fed colostrum.
Concerning the initiation time of complementary feeding, 188 (29.9%) of the mothers started feeding additional food to their children after six months of age. The study further indicated that 199 (25.7%) and 447 (74.3%) of the mothers fed their children by bottle and cup feeding, respectively, as a complement to breast milk.
Regarding the hand washing practices of mothers, 237 (27.4%) of them did not wash their hands at the five critical times. Of the total mothers who reported washing hands at the five critical times 495 (63.9%) of them washed their hands without any detergent. In addition, 595 (96.9%) and 624 (92.4%) of the children were vaccinated for measles and received vitamin A supplementation, respectively. The findings of this study declared that the prevalence of diarrheal disease among children younger than 5 years old was 167 (21.5%) (see Table 3).
Predictors of diarrheal disease among children younger than 5 years old in Jabithennan District, West Gojjam Zone, June 2014
In the bivariate logistic regression analysis between different predictor variables and diarrheal disease in the previous 2 weeks, the age of the mother, residence, number of children younger than 5 years old in a family, sex of the child, time taken to fetch water, type of water storage, availability of a latrine, availability of feces in the compound, domestic animals sharing the same house, time that breastfeeding started, colostrum breastfeeding, methods of complementary feeding and cleansing materials used to wash hands were found to show associations at P-values less than or equal to 0.2.
However, only residence, sex of the child, time taken to fetch water, type of water storage, methods of complementary feeding and cleansing materials used to wash hands appeared in the final condensed model of the multivariable analysis (see Table 4).
The prime objectives of this study were to identify the prevalence and determinants of diarrheal disease among children younger than 5 years old. It was found that more than one-fifth (21.5%) of the children included in the study reported diarrheal disease in the 2 weeks before the survey. This finding was supported by a study performed in Kashmir, India, where the prevalence of diarrhea among children younger than 5 years old was 25.2% . The current finding was also in agreement with studies conducted in Nakemet, Western Ethiopia, and Jigjiga District, Somali Region, Eastern Ethiopia, where the rates of diarrhea among children younger than 5 years old in these two regions were 28.9% and 27.3% respectively [13, 16].
However, the current finding was higher than the finding of the Ethiopian demographic and health survey 2011 (EDHS),in which the magnitude of diarrheal disease among children younger than 5 years old was 13% , and the current finding also higher than a finding from Mecha district, West Gojjiam, Ethiopia, where the prevalence of diarrhea was 18% .
However, the current findings were lower than those of similar studies conducted in rural households in Northwestern Burundi, where the prevalence of diarrhea was 32.6% , and of a study conducted in Arba Minch district, south Ethiopia, where the prevalence of diarrhea reported was 30.5% . The difference could be attributed to the sample size, study period, environmental conditions and socio-economic and cultural differences.
Children from rural communities were more than eleven times more likely to report diarrheal disease, compared to children from urban areas. This finding was supported by a similar study conducted in Sheko district, Southwest Ethiopia, and DebreBirehan Town, North East Ethiopia, where children from families in urban residences were affected by diarrhea [21, 22]. This finding could be attributed to different factors, including access to a safe and adequate water supply, the literacy status of the people, knowledge of hygienic activities and communicable disease prevention and control practices, and to latrine availability being severely limited in rural areas of the country.
The gender of the child was a statistically significant predictor of childhood diarrhea, with boys more than two times more likely to be affected by diarrheal disease than girls. This finding was supported by other studies conducted in Sudan and Nigeria [23, 24].
Although the reason why boys younger than 5 years old were more likely to be affected by diarrheal disease than their female counterparts is beyond the scope of this study, the probable reason is that, in Ethiopia, playing outside of home is allowed for boys, and they begin to participate in economic activities, such as tending to domestic animals in the field when they reach 4 to 5 years of age with their elders; in contrast, girls are not allowed to be involved in out-of-home activities, and they are not permitted even to play outside of one’s own compound . This difference might have contributed to boys having a greater opportunity to wander off into unsanitary surroundings than girls, eventually leading to diarrheal morbidity. This finding was supported by a study conducted in pediatric hospital admissions in Hong Kong: Hon and Nelson (155) reported that boys had a consistent excess in admissions, compared to girls .
In addition, children from households using broad-necked equipment for water storage were at more than 19 times greater risk of diarrhea, compared to children from households using jerry cans (narrow-necked water container). This finding was supported by different studies performed in Lalit pur district, Nepal, Kersa district, Eastern Ethiopia, and Debrebirehan town, Northeast Ethiopia [26–28]. This finding was absolutely the result of water being contaminated at or following collection during transportation and/or storage since the water storage containers are uncovered and broad necked, so they can be contaminated easily by pets, dirt, or other debris .
The findings of this study were also supported by a Centers for Disease Control and Prevention report that found that microbial contamination of water was usually associated with storage vessels having wide openings, such as buckets and pots, which are vulnerable to the introduction of hands, as well as cups and dippers, which can easily carry contamination to the water .
In this particular study, it was found that the odds of diarrheal disease were much higher among children who received bottle methods of complementary feeding, compared to cup methods of feeding. This finding was in accordance with other studies in Nekemit town, Western Ethiopia , and Gondar, Northwest Ethiopia ,where the bottle method of complementary feeding was more likely to be associated with diarrheal diseases. This finding might be associated with improper cleansing of bottles.
Moreover, children of mothers who washed their hands using water only at critical times were more than five times more likely to report diarrhea, compared to children of mothers who washed their hand using water and soap.
The finding was supported by similar studies conducted in Bangladesh [17, 31] and was also supported by similar studies performed Jigjiga District, Somali Region, Eastern Ethiopia, and in Sheko district, Southwest Ethiopia, where mothers’ hand washing habits affected the occurrence of diarrheal disease among their children [16, 21].
The findings of this study revealed that one out of five children had diarrhea in the Jabithennan district, and several factors were found to affect diarrheal disease among children in the district. Therefore, the government, families and nongovernmental organizations working with children and mothers must cooperate regarding interventions to minimize the risks of the disease.
The regional health bureaus and nongovernmental organizations should address the availability of safe drinking water and the sanitation of rural communities, which might be contributing to the occurrence of diarrheal disease among children.
The local government should focus on the accessibility of safe drinking water for the community. In addition, regional and local health officials must work to create awareness about the type of water storage containers that the community should use. Moreover, all mothers should be informed that the cup method of complementary feeding is better than bottle feeding to prevent diarrhea, and concerned bodies must work to create awareness about how mothers use and access hand washing detergents during critical times.
