Abstract
Background: Scabies affects over 200 million people globally, with an estimated 5-50% of children living in communities of limited resources. Scabies is a widespread issue in Ethiopia, particularly during natural or man-made disasters like flooding, drought, and conflict, as well as when there is a lack of access to clean water and sanitary facilities and congested living circumstances. This study aimed to determine the scabies and its determinants among preschool children in East Badawacho District, Hadiya Zone of Central Ethiopia. Methods: A facility-based, unmatched case-control study with 348 participants compared scabies-infested preschool children to non-scabies preschool children for their past exposure to scabies in East Badawacho District, Central Ethiopia. The children's nutritional status was measured anthropometrically and analyzed using WHO Anthro software. Data were entered into EPI Data Version 3.1 and exported to SPSS Version 25 for analysis. Bivariable and multivariable analyses were used to identify determinants of scabies, with statistical significance declared at a P-value less than 0.05. Result: The prevalence of stunting was 50.5% among cases and 45.2% among controls, while the prevalence of underweight was 24.3% among cases and 18% among controls. The prevalence of wasting was 17.8% in cases and 9.3% in controls. Severe wasting [AOR = 2.4, 95% CI: 1.32, 5.47], mothers of preschool children who used less than 20 liters of water for daily activities [AOR = 2.5, 95% CI: 1.02, 6.27], children who shared clothes with someone affected by scabies [AOR = 6.7, 95% CI: 2.98, 15.08], and children who wash their bodies with water only [AOR = 3.4, 95% CI: 1.37, 6.77] were the significant independent predictors associated with scabies infestation. Conclusion: Preschool children who were severely wasted, amount of water utilized for daily activity < 20 litres, sharing of cloth with scabies infected person, washing body with water only had significant role for the transmission of scabies. Therefore, scabies control programs should incorporate nutritional, and water sanitation interventions.

1. Introduction
Scabies is derived from a Latin term that means, "To scratch," and caused by the human itch mite (Sarcoptes scabiei var.hominis) infesting the skin
. It is commonly connected with overcrowding, low socioeconomic standards, a lack of education, and inadequate hygiene is a neglected parasite disease that is a global public health issue, and particularly in resource-limited areas

2.7. Sample Size and Sampling Procedure
The sample size for these preschool children was calculated by Epi Info™ version 7 statistical program using unmatched case control formula and this study was designed to have 80% statistical power with level of significance at 5% and a case to control ratio of 1:2. Assuming an independent factor of bed sharing with scabies infestation 25.3% for controls and 39.8% for cases, the calculated sample size was 354 (118 cases and 236 controls).
Initially, nine health posts out of 27 were selected by a simple random sampling (lottery method) from the district health office. The most recent four weeks' data of children aged 24-59 months in health posts was obtained to allocate samples and calculate their sharing (systematic random sampling). When one clinically confirmed scabies case was found, two controls of parents (caretakers) were interviewed and their child’s anthropometric status had measured based on their order of visiting that health posts where they fulfilled the inclusion criteria. Finally, cases and controls were consecutively selected from each health posts. (
Figure 2)
2.8. Data Collection Method and Tool
The instrument of data collection was a pretested interviewer-administered structured questionnaire. The collected data was through face-to face interview with caregivers. The questionnaire contains the demographic and socio-economic factors of the child and the caretaker, Anthropometric and nutritional information of the child, environmental factors, and behavioral factors.
A total of nine health officers and one supervisor were recruited as data collectors, and they had got two days of training on the aims of the study, data collecting tools, anthropometric measurements, interviewing procedures, and recruiting study participants by the principal investigator. The data collectors were fluent speakers of the Hadiyisa language.
The child's weight was determined using a digital weighing scale, and his /her height was measured standing up using a column-mounted height stadiometer. The children were weighed barefoot and wearing tiny clothing. The weight and height measurements were rounded to the nearest 0.1 kg and 0.1 cm, respectively. Weighing scales are often calibrated. A local calendar was created to improve accuracy in predicting the ages of the children.
2.9. Data Processing and Analysis
Collected data from a structured questionnaire was checked, coded, and entered into EpiData version 3.1 before being exported to SPSS version 25 for analysis. The anthropometric data was exported to the WHO Anthro statistical program, which was used to analyze nutritional indicators. When HAZ, WAZ, and WHZ were less than minus three Z-score, sever stunting, underweight, and wasting were evaluated.
A descriptive analysis of the socio-demographic status of the respondents was made by using tables to see the participant’s characteristics and all independent variables associated with scabies infestation on bivariate analyses with P < 0.25 were candidate for multivariable logistic analysis. Multivariable logistic regression analyses were done for those variables with p-value < 0.25 in the bivariate analysis to control for all possible confounders and to identify factors associated with scabies. The absences of multi-collinearity between different explanatory variables were checked using variance inflation factor (VIF=2.15-2.84) and tolerance (0.5). An adjusted Odds ratio along with 95% CI was estimated to measure the strength of the association. Having a p-value < 0.05 was used to declare the presence of statistically significant association between the independent and dependent variables.
2.10. Data Quality Control
To ensure data quality, data was collected using a structured and pre-tested questionnaire. Pre-test was done in 5% of the calculated sample size at Wera Boya health post, west Badawacho woreda before the actual data collection started to check appropriateness, consistency of the tool and to estimate the time needed for each questionnaire. The necessary adjustments were made in light of the results of the pre-test.
The structured questionnaire was translated into Hadiyyisa, and again translated back to English to check the questionnaire consistency. Two days intensive training was provided about the instruments, ways of data collection, ethical issues and aims of the study for data collectors and supervisor by the principal investigator. To keep completeness and consistency, data collectors is closely supervised before and during the data collection process by the supervisor. The principal investigator supervised the correct implementation of the procedure and checked completeness and logical consistency after data collection.
3. Results
3.1. Socio-Demographic Characteristics of the Study Participants
This study interviewed 348 child caretakers/mothers, with a response rate of 98.3% for cases and controls. The mean age of children was found to be 40 10.1 months for both cases and controls. Nearly half of the respondents were between the ages of 35 years and 44 years with 54 (46.6%) cases and 100 (42.9%) controls. The majority of study participants, 322 (92.5%), were from rural areas, with 26 (7.5%) residing in semi-urban areas for both groups. Regarding marital status, 308 (88.5%) of the mothers in both groups were married. More than half of mothers had a primary education, while 37.8% were illiterate across both categories. The mother's occupation was house wife in three quarters of the cases 88 (75.9%) and 172 (74.2%) of the controls. Regarding to family size, 44 (18.9%) were controls and 103 (88.8%) cases were made up the majority of families larger than five. Thatched roofs were found on 76.6% of cases and 50.2% of control homes.

3.4. Factors Associated with Scabies Among Preschool Children’S East Badawacho District; Hadiya Zone, Central Ethiopia
In the multivariable analysis after adjusting for possible confounding factors the result of multivariable logistic regression analysis showed that, severely wasting, amount of water for daily activity < 20 litres, child sharing of cloth with scabies infected person, and using only water as detergent were found to be significant determinants of scabies.
Severely wasted children (WHZ < −3) had a 2.4 times higher risk of scabies infestation compared to non-wasted children [AOR = 2.4, 95% CI: 1.32, 5.47].
Daily water consumption of less than 20 liters was identified as an independent predictor of scabies. Children from households with less than 20 liters of water per day were 2.5 times more likely to be infected with scabies than children from households with more than 20 liters per day [AOR = 2.5; 95% CI: 1.02, 6.27].
The odds of having a scabies infestation were 6.7 times higher among children who had shared any clothes with someone with scabies than those who had not [AOR = 6.7, 95% CI: 2.98, 15.08]. The odds of getting scabies infestation were 3.4 times higher in children who washed their bodies with water alone than in children who washed their bodies with soap and water [AOR = 3.4, 95% CI: 1.37, 6.77].

4. Discussion
Scabies is a neglected skin infestation occurring worldwide and significantly impacts health and quality of life. The prevalence is high among children, especially those who live in area of low economic status
| [18] | Kline K, McCarthy JS, Pearson M, Loukas A, Hotez PJ. Neglected Tropical Diseases of Oceania: Review of Their Prevalence, Distribution, and Opportunities for Control. PLoS Negl Trop Dis. 2013; 7(1): 1-9. |
[18]
. This study addressed scabies and its determinants among children living in the East Badawacho district. The findings from our study showed that severely wasting, amount of water for daily activity < 20 litres, child sharing of cloth with scabies infected person, and using only water as detergent are determinant factors for scabies.
This study compared the prevalence of malnutrition in preschool children between scabies cases and controls to see the association between malnutrition and scabies. After adjusting for potential confounders, there was a statistically significant association between sever wasting and scabies infestation in preschool children. Severely wasted children were two times more likely to develop scabies compared to non-wasted preschool children.
Understanding how malnutrition affects infections in general is a critical step toward understanding how malnutrition affects scabies specifically. It is well established that malnutrition raises susceptibility to infection, while infection has an adverse effect on nutritional status

. Malnutrition reduces immunity, increasing infection susceptibility. In contrast to the findings, a prior cross-sectional study conducted in Indonesia

[20]
, found no significant association between malnutrition and scabies infestation. The discrepancies might be explained by differences in, sample technique and procedure, adjustment for confounding variables, or variations in scabies prevalence and nutritional status among the study populations. Additionally, socio-economic status and geographical variations, access to health care, and other factors may influence the observed outcomes. Whereas the nutritional status represented by stunting and underweight has no association with the occurrence of scabies infestation in preschool children in this study.
In order to successfully tackle the children's scabies infestation in Ethiopia in general, and in the current study areas in particular, it appears necessary to analyze the contribution of a number of scabies-influencing factors. As a result, this study attempted to investigate factors associated with scabies in the study area while included as many risk factors as possible.
Our study revealed that sharing of clothes with someone who has had an itchy skin lesion in the last two months is one of the major risk factors for scabies. The finding is supported by studies done in Ethiopia

. This could be due to increasing interaction between persons and shared clothing or bedding, as there may be insufficient resources in the home. Sharing of clothes with someone with scabies facilitates the transmission and therefore the spread of scabies mites from infested person to healthy children and children sharing clothes with infected person were more susceptible to severe and repeated infection due to the fundamental role of contact in disease transmission. Since the mites could stay alive on cloth for prolonged time unless complete removal have been made such as bedding and clothing laundered properly, children who are sharing cloths could get the disease easily although medication has been made.
In this study, using simply water to wash the body and clothes was associated with an increased risk of scabies infestation. Previous studies found that using water with soap for hands and clothes on a regular basis prevented scabies infestations more effectively than simply using water. This is in line with a study carried out in Dabat, Ethiopia
| [27] | Henok D, Awrajaw D, Bikes D, Worku YW, Zemichael G. Prevalence and associated factors of scabies among schoolchildren in Dabat district, northwest Ethiopia, 2018. Environ Health Prev Med. 2019; 24(67): 1-8. |

[27, 28]
. The possible assumption could be since detergents are an easy way to get rid of scabies mites, and it is crucial to remove immature mites from the skin to lower the risk of transmission by reducing the mite density.
Amount of water < 20 litres for daily activity was found to be independent determinants of scabies. According to this study, those who consumed less water on a regular basis were also more likely to have scabies. This may be explained by the fact that these homes did not have enough water to do basic household tasks like cleaning the house and washing clothes and bodies with soap. Regarding this, there is proof that bathing with soap on a regular basis can significantly lower the incidence of scabies. Therefore, inadequate domestic and personal hygiene, which may be brought on by a lack of water, could be the cause of this finding. This result is consistent with a matching analysis conducted in rural Ethiopia

5. Strength of the Study
An anthropometric technique to assessing nutritional status (the key exposure variable) reduces the recall biases found in case control studies and a case-control study, which has been more effective in assessing the determinant factors. Because the main exposure factors (age, weight, and height) are measured objectively, there is a small likelihood of recall, selection, or interviewer bias.
6. Limitation of the Study
The diagnosis was made only on clinical grounds; burrow scraping and microscopic investigation were not used to confirm findings. Other variables (apart from anthropometric data) contribute to information bias. Recall bias, and sampling biases are some of limitations of study design.
7. Conclusion
The present study revealed that the major exposure variable (nutritional status) represented by severe wasting has a significant impact on the scabies infestation of preschool children.
The study also shown that child sharing of cloth with scabies infected person, amount of water for daily activity < 20 litres, detergent of water only used were identified as an independent predictors of scabies among preschool children in East Badawacho district.
The government should focus on poverty reduction efforts, and woreda health office should pay special attention for severely acute malnourished children in the prevention and control of scabies. Health professionals should provide health education and sensitization to mothers and caregivers to restrict the sharing of clothing among children and the use of adequate detergents for washing their children's bodies, particularly in families with scabies.
Since malnutrition, particularly sever wasting, has been identified as a significant risk factor for scabies infestation. Therefore, community should focus on improving nutritional status of children through balanced diet, and seeking support from health facilities when necessary.
Further studies at the community level to better understanding of additional factors driving the infestation by scabies.

abstract = {Background: Scabies affects over 200 million people globally, with an estimated 5-50% of children living in communities of limited resources. Scabies is a widespread issue in Ethiopia, particularly during natural or man-made disasters like flooding, drought, and conflict, as well as when there is a lack of access to clean water and sanitary facilities and congested living circumstances. This study aimed to determine the scabies and its determinants among preschool children in East Badawacho District, Hadiya Zone of Central Ethiopia. Methods: A facility-based, unmatched case-control study with 348 participants compared scabies-infested preschool children to non-scabies preschool children for their past exposure to scabies in East Badawacho District, Central Ethiopia. The children's nutritional status was measured anthropometrically and analyzed using WHO Anthro software. Data were entered into EPI Data Version 3.1 and exported to SPSS Version 25 for analysis. Bivariable and multivariable analyses were used to identify determinants of scabies, with statistical significance declared at a P-value less than 0.05. Result: The prevalence of stunting was 50.5% among cases and 45.2% among controls, while the prevalence of underweight was 24.3% among cases and 18% among controls. The prevalence of wasting was 17.8% in cases and 9.3% in controls. Severe wasting [AOR = 2.4, 95% CI: 1.32, 5.47], mothers of preschool children who used less than 20 liters of water for daily activities [AOR = 2.5, 95% CI: 1.02, 6.27], children who shared clothes with someone affected by scabies [AOR = 6.7, 95% CI: 2.98, 15.08], and children who wash their bodies with water only [AOR = 3.4, 95% CI: 1.37, 6.77] were the significant independent predictors associated with scabies infestation. Conclusion: Preschool children who were severely wasted, amount of water utilized for daily activity < 20 litres, sharing of cloth with scabies infected person, washing body with water only had significant role for the transmission of scabies. Therefore, scabies control programs should incorporate nutritional, and water sanitation interventions.},

AB - Background: Scabies affects over 200 million people globally, with an estimated 5-50% of children living in communities of limited resources. Scabies is a widespread issue in Ethiopia, particularly during natural or man-made disasters like flooding, drought, and conflict, as well as when there is a lack of access to clean water and sanitary facilities and congested living circumstances. This study aimed to determine the scabies and its determinants among preschool children in East Badawacho District, Hadiya Zone of Central Ethiopia. Methods: A facility-based, unmatched case-control study with 348 participants compared scabies-infested preschool children to non-scabies preschool children for their past exposure to scabies in East Badawacho District, Central Ethiopia. The children's nutritional status was measured anthropometrically and analyzed using WHO Anthro software. Data were entered into EPI Data Version 3.1 and exported to SPSS Version 25 for analysis. Bivariable and multivariable analyses were used to identify determinants of scabies, with statistical significance declared at a P-value less than 0.05. Result: The prevalence of stunting was 50.5% among cases and 45.2% among controls, while the prevalence of underweight was 24.3% among cases and 18% among controls. The prevalence of wasting was 17.8% in cases and 9.3% in controls. Severe wasting [AOR = 2.4, 95% CI: 1.32, 5.47], mothers of preschool children who used less than 20 liters of water for daily activities [AOR = 2.5, 95% CI: 1.02, 6.27], children who shared clothes with someone affected by scabies [AOR = 6.7, 95% CI: 2.98, 15.08], and children who wash their bodies with water only [AOR = 3.4, 95% CI: 1.37, 6.77] were the significant independent predictors associated with scabies infestation.
