Abstract
Background
According to the World Health Organization, hygiene is the process of cleaning an environment of all sickness factors that may cause health problems and involves all the precautions to be taken to reduce microorganisms (Mahmudiono et al., 2020). Creating hygienic environments is a critical part of breaking the fecal-oral transmission route for many diarrhea and other illnesses (World Health Organization, 2023). Diarrhea and other illnesses, access to safe water and hygiene facilities is a basic human challenge for survival and well-being (World Health Organization, 2023). Using improved hygiene facilities such as clean and safe water in facilities that can effectively prevent human, animal, and insect contact with excreta by using protected pit latrines to flush toilets with a sewerage connection is very important (Mahmudiono et al., 2020). The evidence above suggests that poor hygiene has become a pressing and significant public health issue. In Ethiopia, most household mothers have a greater role in maintaining housekeeping and environmental hygiene than men. Infants and children expose to diarrheal diseases during household women food poor hygienic way preparations (Mengistie & Baraki, 2010). Studies have shown that diarrheal incidence increases when the house and environment are usually introduced as unhygienic handling methods as sources of diarrheal pathogens (Miko et al., 2013; Nath, 2003) and when those who have access to improve household hygiene facilities have great health benefits, ranging from reductions in diarrheal disease, helminth infections, and trachoma to a reduced risk of accidents and enhanced psychosocial well-being (Dhimal et al., 2014). Improper handling of the house and environment at the household level can contribute to different infectious diseases caused by enteric pathogens associated with preventable food-borne bacteria (Wasonga et al., 2014). However, there is a need for primary study to clearly determine the bottleneck problems.
Globally, 2.3 billion people still lack basic hygiene including 670 million with no handwashing facilities at all (JMP, WHO, UNICEF, 2021). Similarly, 1.9 million deaths and 123 million disability-adjusted life years (DALYs) are associated with poor hygiene-related infectious diseases due to inadequate water. The disease burden attributable to inadequate water and hygiene accounts for 4.6% of global DALYs and 3.3% of global deaths (World Health Organization, 2019). A causal link between hand hygiene and the rate of infectious disease illness has also been established. Hand hygiene is any action of hand cleansing, that is, the act of cleaning one’s hands with or without the use of water or another liquid or with the use of soap to remove soil, dirt, and/or microorganisms (World Health Organization, 2017, 2019). In Africa, poor hygiene of houses and their environments is a common problem (Degebasa et al., 2018). In 2020, it is estimated that more than 208 million people in Africa practiced open defecation, 839 million people lacked basic hygiene services, and diarrheal diseases are listed as the top killers of children in developing countries (JMP, WHO, UNICEF, 2021). Significant inequalities persist between and within countries including between urban and rural settings (Hutton & Chase, 2016). In Ethiopia, 20 million people practice open defecation, and 106 million people still lack basic hygiene services (JMP, WHO, UNICEF, 2021). Improving water and hygiene practices at the household level is the most effective intervention measure to prevent and control the burden of diarrhea and other communicable diseases since mothers always prepare food. For instance, proper handwashing with soap, use improved water quality, and proper excreta disposal can reduce diarrheal diseases by 48%, 17%, and 36%, respectively (Cairncross et al., 2010). These factors are important for reducing diarrheal diseases by maintaining housekeeping and compound hygiene, yet there is a high client flow at health facilities for related infectious diseases (Teshome et al., 2023).
Sociodemographic factors such as good educational status and type of house (having a modern house) create favorable conditions for increased knowledge and hygienic practices (Yallew et al., 2012). Environmentally related factors such as the presence of latrines at the household level and hand washing facilities are also associated with an increased status of good knowledge and hygiene practices, whereas open defecation (OD), access to safe disposal of human excreta, awareness of hygienic practices, and use of non contaminated water are associated with an increased status of good knowledge and hygiene practices (Johnson et al., 2015; Yallew et al., 2012). Similarly, knowledge of handwashing and latrine use is also significantly associated with good hygiene practices (Shehmolo et al., 2021).
The substantial benefits of hygiene improvements have been gained from the health extension program, which was designed and implemented by the Ethiopian Ministry of Health (MOH) since 2003 (Assefa et al., 2019). The WASH National Program and the Growth and Transformation Plan (GTP) have been implemented and have played a great role in improving hygiene infrastructure throughout the country (Girma et al., 2024; SWAp AM-S, 2013). Although these programs are implemented in Ethiopia, infectious diseases among children under 5 years of age are prevalent in the study area.
Although knowledge and practices related to hygiene influence household mothers’ hygiene behaviors, this topic remains under-researched (Teshome et al., 2023). In the study area, despite health extension workers’ efforts, diarrheal diseases remain common, according to annual reports from the district health office. This study aimed to assess the knowledge, practices, and associated factors of household and environmental hygiene among mothers in Tegede district, Central Gondar Zone, Amhara Region, Northwest Ethiopia. The findings will support healthcare providers and policymakers in designing targeted interventions to improve maternal and child health.
Methods
Study Design
A community-based cross-sectional study was conducted among household mothers in the Tegedie district from August 20, 2022, to September 15, 2022. The Tegedie district is one district of the Central Gondar Zone and is located in northwestern Ethiopia. It is located 115 km from Gondar town and 295 km from Bahir Dar City. The district consists of one primary hospital, four governmental health centers, and 26 health posts. The district is structured into 21 kebeles (2 urban and 19 rural). According to reports from the Tegedie District Health Office, 100,382 people (53,829 males and 46,553 females) live in the district (Teshome et al., 2023). The presence of latrines at the household level and the water coverage of the district are 14% and 63.8%, respectively. Malaria, diarrhea, intestinal parasites, and upper respiratory tract infections are the main health problems in the general community (Teshome et al., 2023).
Participants
All household mothers who lived for at least 6 months in the district were considered the source population, while all household mothers who lived for at least 6 months in each kebele during the data collection period were considered the study population.
Inclusion and Exclusion Criteria
Inclusion and exclusion criteria were clearly defined to minimize selection bias. All household mothers residing in the study area for at least 6 months during data collection were included. Mothers who were seriously ill or unable to hear were excluded.
Sample Size Determination
The sample size was determined using a single population proportion formula. Accordingly, the formula for sample size determination used was
The sample size was also calculated using the second objective of associated factors with knowledge and practice of hygiene by considering the following assumptions: two-sided confidence interval = 95%; power = 80%; ratio (unexposed to expose) = 1; design effect (DE) = 1.5; and 10% non response rate (NR; Table 1).
Sample Size Calculation With Associated Factors.
More importantly, the sample size obtained by using the single population formula (634) was greater than the sample size calculated by using the second objective (using factors significantly associated with the outcome variable). Therefore, the minimum sample size to represent the source population was 634.
Sampling Technique
A two-stage sampling technique was used. First, 10 kebeles (about half of the 21 kebeles in Tegedie district) were selected by simple random sampling (lottery method). The sample size was proportionally allocated to each kebele based on its population. Mothers were then selected systematically at the household level, with a sampling interval of approximately 14 (K = total mothers ÷ allocated sample), selecting every 14th household (Figure 1).

Variables and Measurements
The outcome variables of this study were knowledge and practice of household and environmental hygiene. The explanatory variables included sociodemographic factors (age, religion, ethnicity, residence, marital status, family size, occupation, family income, education level, and media access), attitudes, environmental health, and housing-related factors.
The questionnaire was developed by reviewing previous studies (Abdul et al., 2020; Degebasa et al., 2018; Sultana et al., 2016). It was first prepared in English, then translated into Amharic, and back-translated into English by language experts to ensure consistency. Hygienic practices related to housing and environmental hygiene were assessed using a 22-item questionnaire, including observational questions with a scoring scale above three points and some yes/no questions. The mean score of responses was calculated, and participants scoring at or above the mean were classified as having good hygiene practices; those below were considered to have poor hygiene practices (Berhe et al., 2020).
Household mothers’ knowledge of house and environmental hygiene was assessed using 12 related questions for categorical analysis. Participants scoring at or above the mean total score were considered to have good knowledge; otherwise, they were classified as having poor knowledge (Berhe et al., 2020). Attitudes toward housing and environmental hygiene were assessed with 16 questions. Total attitude scores were calculated, then dichotomized as favorable (≥mean) or unfavorable (<mean; Afework et al., 2022).
Data Quality Management
A pretest was conducted with 5% of the sample (32 participants) from outside the study area (Layrmachiho District), and necessary revisions were made based on the results. Data collectors received training on the study’s purpose, procedures, inclusion/exclusion criteria, questionnaire review, interviewing techniques, and data collection methods. Daily supervision was conducted by a master’s-level environmental health professional. Ten BSc health officers and environmental health providers collected data through interviews and direct observation using structured, pretested questionnaires. The principal investigator reviewed each questionnaire daily for completeness before data entry. Participants were informed about the study’s purpose to create a comfortable environment and reduce stress, given the sensitive nature of the topics.
The questionnaire’s content validity was confirmed by experts, and reliability was established using internal consistency (Cronbach’s alpha = 0.75). Multicollinearity was assessed with variance inflation factors (VIF < 1.5). Model fit was confirmed by the Hosmer–Lemeshow test (knowledge
Data Processing and Analysis
The data were checked for completeness, coded, entered into Epi-data 4.6, and then exported to SPSS version 23 for cleaning and further analysis. For each question, the participants were given a score of one point for each correct answer and 0 (zero) points for the incorrect answer about the house and environment hygiene-related questions. The responses were added, and the mean was computed. Descriptive statistics were carried out and are presented with tests, figures, and tabulations.
The associations of each independent variable with the outcome variables were determined using univariable binary logistic regression analysis. Furthermore, variables with a

Environment-Related Factors
Three hundred sixty-eight (58%) of the study participants had access to a private latrine. Of these, only 119 (18.8%) of the participants had latrines with handwashing facilities, and only 67 (10.6%) had functional water and soap during the data collection period. Regarding access to a safe water supply, many of the participants (349; 55.0%) received water from piped water sources. This revealed that a greater proportion of mothers (464 (73.2%) had collected water within 30 min. Regarding the individual daily amount of water utilization, 522 (82.3%) of the study participants used 20 liters per capita per day (L/C/D). Regarding the water treatment option, 461 (72.7%) of the participants did not treat the water during utilization. In the case of waste disposal, nearly half of the participants (50.5%) disposed of waste in open fields (Table 3).

Level of Knowledge, Practice of House and Environment Hygiene
The results of this study showed that the overall levels of good knowledge and practice of housing and environmental hygiene were 72.34% CI [68.9, 75.7] and 58.67% CI [54.7, 62.5], respectively (Figure 2).

Factors Associated With Good Knowledge of the House and Environmental Hygiene
The relationships between all potential independent variables with good knowledge of housekeeping and environmental hygiene were analyzed using binary logistic regression. Accordingly, maternal age group, ethnicity, marital status, educational level of mothers, family size, residence, access to media, presence of latrine, type of water source, reliability of water throughout the year, waste disposal management system, presence of livestock, presence of flies in the house, place of cooking, and presence of animal feces near the household were analyzed using binary logistic regression. Finally, urban residence, access to media, fly presence in the house, and place of cooking food were factors significantly associated with good knowledge of housing and environmental hygiene.
Urban dwellers were 1.61 (AOR: 1.61; 95% CI [1.04, 2.49]) times more likely than rural dwellers to have good knowledge about housing and environmental hygiene. Participants who have access to media were 1.82 (AOR: 1.82; 95% CI [1.17, 2.84]) times more likely to have good knowledge about housing and environmental hygiene than those who did not have access to housing and environmental hygiene information in the media. Those who had flies were 1.77 (AOR: 1.77; 95% CI [1.08, 2.91]) times more likely to have good knowledge about housing and environmental hygiene. Additionally, those study participants who made food in a separate room were 1.89 times more likely to have good knowledge of housing and environmental hygiene than those who made food inside the main living room (AOR: 1.89; 95% CI [1.13, 3.18]). Those study participants who made food in an open space outside the household were 4.72 times more likely to have good knowledge of housing and environmental hygiene than were the study participants who made food inside the main living room (AOR: 4.72; 95% CI [1.66, 13.56]; Table 4).

Factors Associated With Good Hygiene Practices in the House and the Environment
Maternal age group, marital status, maternal educational level, maternal occupation, family size, residence, access to media, presence of latrines, presence of handwashing facilities, type of water source, presence of livestock, reliability of the water source throughout the year, access to water source, water consumption in liters per capita per day (L/C/D), and knowledge about house and environment hygiene were identified as predictor variables in the univariable binary logistic regression analysis. However, only maternal age group, place of residence, access to media, presence of a latrine, and access to a water source near to house within 30 min were significantly associated with hygiene practices among mothers.
Accordingly, participants aged 18 to 26 years were 6.09 years (AOR: 6.09; 95% CI [3.04, 12.19]), those aged 27 to 35 years were 3.43 years (AOR: 3.43; 95% CI [2.05, 5.74]), and those aged 36 to 44 years were 2.02 years (AOR: 2.02; 95% CI [1.20, 3.40]) more likely to practice good hygiene than those aged 45 to 70 years. Those participants who lived in urban areas had 2.71 times (AOR = 2.71, 95% CI [1.79, 4.12]) greater odds of good practices than those who lived in rural areas. Study participants who had access to media were 44% less likely to practice good hygiene than their counterparts were (AOR : 0.66, 95% CI [0.45, 0.98]). Study participants who had a private latrine at the household level were 2.27 times more likely to practice good hygiene than those who did not have a private latrine at the household level (AOR: 2.27, 95% CI [1.50, 3.45]). This study revealed that participants in households with access to a water source within 30 min of their homes were 60% less likely to practice good hygiene than participants in households with access to a water source more than 30 minutes away (AOR:0.40, 95% CI [0.26, 0.62]; Table 5).

Discussion
This study aimed to assess the level of knowledge, practices, and associated factors of housing and environmental hygiene among household mothers in the Tegedie district. The overall prevalence of good knowledge was 72.34% (95% CI [68.9, 75.7]), and good hygiene practice was 58.67% (95% CI [54.7, 62.5]).
The level of knowledge about housing and environmental hygiene in this study aligns with findings from peri-urban Northwest Ethiopia (75.7%; Berhe et al., 2020), and Nepal (74.28%; Sah et al., 2017). The possible explanations for these similarities might be the similar sociodemographic characteristics of the study participants and the fact that all those studies were community-based and in rural areas. However, it is higher than reports from northern Ethiopia (42.2%; Berhe et al., 2020), southern Ethiopia (62.1%; Afework et al., 2022), and Angola, Ethiopia (52%; Vivas et al., 2011). These differences may stem from variations in study periods and participant characteristics, such as the exclusively rural population in northern Ethiopia (Berhe et al., 2020) and inclusion of school-age children in Angola (Vivas et al., 2011).
The percentage of good house and environmental hygiene practices (58.67%) was lower than in Rwanda (66.3%; Nikwigize, 2022), Addis Ababa, Ethiopia (74%; Gebreeyessus & Adem, 2018), and Arsi Nagele Town, Southeast Ethiopia (68.1%; Mako et al., 2019). The possible reasons behind these differences might be the level of education of the study participants. This difference may be due to lower education levels among participants in this study compared to those in Addis Ababa (Gebreeyessus & Adem, 2018) the fact that 93% of participants in Arsi Nagele Town were educated (Mako et al., 2019). However, the result aligns with findings among mothers in Nepal (60%; Sah et al., 2017). In contrast, the level of good housing and environmental hygiene practices (58.67%) was higher than the 49.2% reported in a previous study in Tigray, Ethiopia (Berhe et al., 2020). This difference may be due to variations in the measurement tools used and the study periods.
The study found that participants living in urban areas had higher odds of good hygiene knowledge compared to those in rural areas. This may be because urban residents have easier access to information through various mass media outlets, increasing their awareness of proper household hygiene. This aligns with a Tanzanian study (Alexander et al., 2019) showing that media access significantly improves hygiene knowledge. Additionally, participants whose homes were free of flies were more likely to have good hygiene knowledge, consistent with Ethiopian studies (Tesfaw et al., 2023), indicating that better knowledge helps maintain cleaner homes and reduces fly breeding. Furthermore, those who cooked food in open spaces outside the main living area showed greater hygiene knowledge than those cooking inside the main house. This matches findings from Dedo, Southwest Ethiopia (Eshete Soboksa & Nenko Yimam, 2017), suggesting that cooking outside promotes cleanliness in the living area, likely because having a separate kitchen reduces contamination and supports better hygiene practices overall.
Studies show that household mothers aged 18 to 26, 27 to 35, and 36 to 44 years are more likely to have good hygiene practices compared to those aged 45 to 70 years. This aligns with findings from southern Ethiopia (Shehmolo et al., 2021), where younger age groups were significant predictors of better hygiene. This may be due to differences in education: nearly 98% of those aged 45 to 70 had no formal education, whereas 55.2%, 81.6%, and 90.8% of the younger age groups had some education. Additionally, reduced physical activity with age may limit older participants’ ability to maintain good hygiene practices.
Living in urban areas was significantly associated with better hygiene practices compared to rural areas, likely due to sociodemographic differences and urbanization pressures that encourage improved hygiene. Interestingly, this study found that access to media reduced the likelihood of poor hygiene practices. While this may seem counterintuitive, it suggests that media mainly influences knowledge rather than long-term behavioral change, which is essential for consistent hygiene practices. Thus, media access may improve awareness but does not always translate immediately into better hygiene habits.
Consistent with studies in Gondar City (Sahiledengle et al., 2018), Addis Ababa (Yallew et al., 2012), Gedeo Zone, South Ethiopia (Eshete Soboksa & Nenko Yimam, 2017), this study found that mothers with household latrine access were more likely to practice good hygiene than those without. This may be because having a latrine at home provides the opportunity for proper use, which supports better overall hygiene practices among participants.
Participants with water sources within a 30-min round trip were less likely to practice good hygiene than those with water sources farther away. This unexpected finding may relate to the quantity of water available rather than proximity; only 13.7% of those with closer water access received adequate daily water per capita, compared to 20.6% of those traveling longer distances. Further research is recommended to explore this association.
Strengths and Limitations of the Study
This study was conducted at the community level, so the findings could be a better representation of the source population. Despite this cross-sectional design, which prevented causality determination, we did not include qualitatively addressable data. Social desirability bias and recall bias might be introduced while interviewing the study participants.
Conclusions
These findings show that household and environmental hygiene knowledge and practices are insufficient, influenced by factors like maternal age, urban residence, media access, flies’ presence, food preparation location, latrine availability, and water access. To address this, targeted hygiene training and counseling for mothers are essential. Policymakers and health professionals must collaborate to deliver clear, evidence-based messages, while health workers and women’s groups should actively promote hygienic home practices. Emphasis on latrine use, hygiene facilities, and separate food preparation areas is crucial, especially in rural areas, to improve maternal and child health outcomes.
