Sidoarjo Regency Achmad Sholeh Farhat1*. Mochammad Bagus Qomaruddin2 Public Health Study Program. Airlangga University,Indonesia Corresponding author: E-mail: achmad. farhat-2022@fkm. Abstract. Diarrhea is a public health problem that significantly contributes to morbidity, particularly in vulnerable age groups such as under-five children. Various efforts to treat diarrhea have been implemented through primary health care, but the incidence of diarrhea in under-five children remains quite high, including in the Waru Community Health Center in Sidoarjo, which experienced an increase in diarrhea cases in 2023-2025. The incidence of diarrhea in under-five children is influenced by various interrelated factors, particularly environmental and behavioral factors, which, according to Hendrik L. Blum's theory of health determinants, play a role in influencing health status. This study aims to analyze the relationship between environmental and behavioral factors and the incidence of diarrhea in under-five children in the Waru Community Health Center in Sidoarjo. This study was a quantitative, observational, and analytical study using a crosectional approach. It was conducted among 89 mothers of under-five children who visited the Waru Community Health Center in Sidoarjo from January to March Data were collected through interviews using questionnaires and direct observation of the environmental sanitation conditions of the respondents' homes. Data analysis was conducted using descriptive and inferential statistics with the chisquare test. The results showed that among environmental factors, the condition of healthy latrine could not be statistically tested . , while clean water sources . = 0. , household waste management . = 1,. , and wastewater drainage systems/SPAL . = 1,. were analyzed. Meanwhile, behavioral factors included the use of healthy latrines . = 0. , handwashing with soap . = 0. , drinking water treatment . = 0. , and exclusive breastfeeding . = 0. This study concluded that the use of healthy latrine and exclusive breastfeeding were factors associated with the incidence of diarrhea among under-five children in the Waru Community Health Center in Sidoarjo. The Community Health Center is recommended to conduct regular monitoring and mapping of at-risk areas as a basis for determining priority diarrhea prevention interventions. Keywords: Behavioral Factors. Diarrhea. Environmental Factors and Under-Five Children. INTRODUCTION Diarrhea is a health disorder of the digestive system that remains a significant problem. According toWorld Health Organization . Diarrhea is defined as three or more loose or watery bowel movements per day. Diarrhea remains a leading cause of morbidity and mortality across all age groups and regions In 2021, diarrheal diseases caused 1. 2 million deaths worldwide. (Liang et al. , 2. This disease not only affects children but also significantly impacts older age groups. Children under 5 years old have the highest mortality rate among all age groups, followed by those aged 70 years and older. (Liang et al. This shows that diarrhea remains a global public health problem that requires serious attention because it affects the productivity and quality of life of people of all ages. According to the 2023 Indonesian Health Survey (SKI), the prevalence of diarrhea among all age groups in Indonesia reached 4. This figure is still relatively high and indicates that national diarrhea management efforts have not been fully effective in reducing the burden of diarrheal disease. Specifically, data from the Central Statistics Agency (BPS) of East Java Province recorded 183,338 cases of diarrhea in Several areas with the highest number of cases included Surabaya City with 22,327 cases, followed by Sidoarjo Regency with 12,177 cases, and Malang Regency with 11,826 cases. (Central Statistics Agency. Seeing the high incidence of diarrhea, the government has implemented various mitigation efforts by improving basic health services and implementing standard procedures in primary health care facilities. International Journal of Health and Pharmacy According to the 2024 Sidoarjo Regency Health Profile report, all diarrhea patients in each community health center (Puskesma. area received treatment according to national guidelines, including oral rehydration salts (ORS) and zinc supplementation, with 100% coverage across all age groups. Furthermore, the detection and treatment of diarrhea cases at Puskesmas is also high, with most areas achieving over 90% of the established service target. (Sidoarjo Regency Health Office, 2. However, even though these various interventions have been implemented, the number of diarrhea cases in Sidoarjo Regency is still quite high at 44,414 cases. (Sidoarjo Regency Health Office, 2. Based on data from the Sidoarjo Regency Health Office in 2025, the number of diarrhea cases in toddlers was still found in all community health centers (Puskesma. working areas, with varying numbers. Waru Community Health Center recorded 1,106 cases, ranking second in the number of toddler diarrhea cases in Sidoarjo Regency. This position indicates that the burden of diarrhea cases in toddlers in the Waru Community Health Center's working area is still relatively high compared to most other community health centers. The number of diarrhea cases in toddlers in the Waru Community Health Center working area during 2023Ae2025 still shows a high number. In 2023, there were 1,920 cases recorded, then decreased to 1,097 cases in 2024, and increased again to 1,106 cases in 2025. Despite the decrease compared to 2023, the number of diarrhea cases in toddlers in the Waru Community Health Center working area remains above 1,000 cases per year and indicates a high caseload, and shows an increase again in 2025. This indicates that the incidence of diarrhea in toddlers is still influenced by various interrelated factors in maintaining health. Understanding the factors that influence health status is needed to identify the causes that contribute to the still high incidence of diarrhea in toddlers. According to Hendrik L. Blum . in the book(Pakpahan, 2. explains that a person's health status is influenced by various factors known as health determinants. These determinants include environmental factors, behavior, health services, and heredity, which are interrelated and play a role in determining the health level of individuals and communities. Therefore, the factors that cause diarrhea vary, including environmental conditions, individual behavior in maintaining personal hygiene, the community's level of knowledge about diarrhea prevention, and poor nutritional status. (Prawati, 2. According to Susana . in(Pebrianti & Astuti, 2. , states that an individual's health condition is largely determined by their daily habits and behaviors. Furthermore, certain individual behaviors, such as not washing hands before eating, not washing hands after defecation, improper waste disposal, and not exclusively breastfeeding for the first 4 to 6 months, can increase the risk of diarrheal disease. This condition is often related to the community's lack of ability and willingness to seek information about diarrheal (Prawati, 2. This is in line with a study entitled "Analysis of Factors Associated with Diarrheal Incidence in Babai Village. Central Kalimantan. " The analysis showed that inadequate knowledge, suboptimal behavior, negative commitment, and poor environmental sanitation were significantly associated with diarrheal The study explained that these four factors are important determinants influencing diarrheal (Pefbrianti & Astuti, 2. In addition, there is a similar study entitled "Literature Review: Overview of Home Environmental Sanitation Conditions with the Incidence of Diarrhea in Toddlers. " The results of the study indicate that various components of environmental sanitation, such as the availability and quality of clean water sources, the condition and use of latrines, wastewater disposal systems (SPAL), household waste management, and the type of floor covering in the house are related to the incidence of diarrhea in toddlers. This study confirms that home environmental sanitation that does not meet health requirements plays a significant role in increasing the risk of diarrhea, so that environmental factors are one of the main determinants of diarrhea incidence in the toddler age group. (Farkhati, 2. Based on various previous studies, the incidence of diarrhea is influenced by various factors. Although many studies have examined several factors related to the incidence of diarrhea in toddlers, the results of these studies still show variations in findings influenced by differences in regional characteristics, environmental conditions, and local community behavior. These differences in characteristics indicate that factors related to the incidence of diarrhea in toddlers can differ between regions, so that research results obtained in one region may not necessarily reflect conditions in other regions. Furthermore, although International Journal of Health and Pharmacy diarrhea management coverage in Sidoarjo Regency has reached 100%, the number of diarrhea cases remains relatively high. This indicates that factors related to diarrhea incidence need to be assessed according to local community conditions. This condition is in line with Hendrik L. Blum's theory that public health is influenced by four main factors: behavior, environment, health services, and heredity. Among these four factors, environmental and behavioral factors are the most dominant in determining public health status. Therefore, this study is important to identify the relationship between environmental and behavioral factors with the incidence of diarrhea in toddlers in the working area of the Waru Community Health Center. Sidoarjo Regency. II. METHODOLOGY This study used a quantitative approach with a descriptive analytical research type and a crosectional design. This approach aims to analyze the relationship between environmental factors and behavioral factors based on Hendrik L. Blum's theory with the incidence of diarrhea in toddlers without providing treatment or intervention to respondents.

The sample size was determined using the Lemeshow formula to obtain a minimum sample size of 89 toddlers. The sampling technique used probability sampling with a simple random sampling method, so that each member of the population had an equal opportunity to be selected as a respondent. Sample selection was carried out through a data cleaning process, assigning numbers to all population members who met the criteria, and then randomizing using Microsoft Excel to obtain the required sample size. Data collection was conducted using primary and secondary data. Primary data were obtained through interviews using questionnaires and direct observation of the respondents' home environment. The questionnaire was used to obtain information on respondent characteristics, behavioral factors, history of exclusive breastfeeding, and the incidence of diarrhea in toddlers, while the observation sheet was used to assess environmental sanitation conditions, including the condition of healthy latrines, clean water sources, household waste management, and wastewater drainage (SPAL). Secondary data were obtained from documents and reports from the Waru Community Health Center in Sidoarjo Regency, which were used to support the research data. Before use, the research instrument was first tested on 30 respondents who met the research criteria to ensure its validity and reliability. The obtained data were processed through editing, coding, entry, and cleaning stages using SPSS Next, the data were analyzed univariately to describe the frequency distribution and percentage of each research variable. Bivariate analysis was performed using the Chi-Square (NA) test to determine the relationship between environmental and behavioral factors with the incidence of diarrhea in toddlers. If the requirements for the Chi-Square test were not met, the analysis was performed using Fisher's Exact Test as an alternative test. The relationship between variables was declared significant if the p-value obtained was O i.
