Abstract

Stunting, a prevalent health issue in Indonesia, has been found to have a significant impact on the overall well-being of children, with a prevalence rate of 24.4%. This condition not only affects physical growth but also puts children at a heightened risk of various infections, including those caused by intestinal protozoa. Therefore, this study aimed to determine the relationship between personal hygiene parenting style and environmental sanitation with intestinal protozoa infection among stunted children in Sugerkidul Village, Jember District, Indonesia. The participants included were 30 stunted children. Questionnaires were used to collect data on personal hygiene parenting style and environmental sanitation, while microscopic stool examination was conducted to identify intestinal protozoa infection. The results showed that 26.7% of stunted children were infected with intestinal protozoa such as Giardia lamblia (13.3%), Blastocystis hominins (3.3%), and Cryptosporidium parvum (10%). Statistical analysis using Fisher's exact test showed a significant association between environmental sanitation and intestinal protozoa infection. However, there was no association between personal hygiene parenting style and this infection among stunted children in Sugerkidul Village. Therefore, to prevent intestinal protozoa infection, it is necessary to improve environmental sanitation.

Abstract

Introduction: Clean and Healthy Living Behavior (CHLB) is essential to be applied by the community, especially workers who work in the fields of construction, furniture, and others. Workers sometimes do not pay attention to CHLB, so many diseases and even deaths occur due to a lack of awareness of the importance of CHLB. This study analyzes the factors influencing CHLB in the workplaceon informal wood furniture workers at the Occupational Health Effort (OHE) posts. Methods: This type of research is quantitative with an analytical observational approach. The population was all members of the OHE posts in the Kendit Health Center working area in the Situbondo Regency, totaling 40 people. Results: The results that significantly affected workers' attitudes towards CHLB at work on informal wooden furniture workers were knowledge, attitude, infrastructure, workforce and funding. The attitudes about CHLB can also be the basis (foundation) of changes in CHLB behavior in the workplace on informal workers. The results of the observations showed that there were still many workers who smoked and did not wear PPE at work even though these workers had already known that cigarettes contain chemicals that are harmful to health. The adequate facilities and infrastructure at the OHE posts could improve the behavior of CHLB in the workplace. The findings at OHE posts at the Kendit's working area related to funding showed that all members of OHE posts have agreed on a monthly health fund contribution, but this is still not going well. Conclusion: Therewas an influence of attitude and adequate infrastructure at OHE posts on CHLB in the workplace. However, knowledge, workforce, and funding at OHE posts did not have significant effect on CHLB in the workplace.

Abstract

Introduction: Staphylococcus aureus foodborne disease is caused by the consumption of food contaminated with Staphylococcus aureus enterotoxins. Milk is a type of food that contains many nutrients but is susceptible to contamination by Staphylococcus aureus. Jember is one of the districts in East Java that produces cow milk. Previous research showed that the level of milk consumption in the community in 2018 was 3.1 kg/capita/year and 42% consumed pasteurized milk, which has lower quality and may still be contaminated with bacteria. The purpose of this study was to determine the relationship between milking hygiene and Staphylococcus aureus contamination. Methods: A cross-sectional study was conducted involving 36 cow milkers with traditional milking, selected by total sampling. The independent variable was milking hygiene and the dependent variable was Staphylococcus aureus contamination. Milking hygiene practice data were collected through direct observation using a questionnaire. Staphylococcus aureus contamination data were tested using Total Plate Count (TPC) and identified using Gram staining and catalase tests. Results and Discussion: The TPC test results showed that 61.1% of cow's milk fulfilled the Indonesian National Standard for Staphylococcus aureus contamination. There was a relationship between milking hygiene and Staphylococcus aureus contamination. The most influential milking hygiene was cage, udder, and teat hygiene. Conclusion: Staphylococcus aureus contamination did not meet the standards. Therefore, improving the sanitation and hygiene of cages, as well as udder and teat hygiene by dairy farmers, is necessary.

Abstract

Introduction: Geohelminth infections are a neglected global health problem. Data from the World Health Organization (WHO) in 2020 show that more than 24% of the world population is infected by geohelminths. The condition of the agricultural soil, which tends to be loose and moist, supports the development of the infective form of the geohelminth. This makes agricultural communities susceptible to geohelminth infections. This study aimed to determine a spatial map of geohelminth infection in agricultural communities and its contamination in the soil of Jatian Village, Jember Regency. Methods: This study used an observational analytical design and a spatial analysis approach. Sampling was performed using a random sampling method that included 43 samples. Data were obtained by examining soil and stool samples and the coordinates of the sampling locations. Data were analyzed using spatial analysis. Results and Discussion: The results of this study indicated that the prevalence of geohelminth infection in agricultural communities was 23.3%, and its contamination in the soil was 6.98%. Hookworms caused infections among respondents, and contamination in the ground was caused by Hookworms and Strongyloides stercoralis. Clustering analysis results showed that geohelminth infection formed two secondary clusters. Spatial autocorrelation and buffer analysis showed clustering of geohelminth infections within the buffer range (<100 m), indicating that the infection spreads more easily within the cluster. Conclusion: The spatial map showed the distribution pattern of clustered geohelminth infection cases and their contamination in soil within proximity, thereby increasing the risk of geohelminth transmission.

Abstract

The most common worm infections are those caused by soil-transmitted helminths (STH) infection. Soil contamination is one of the causes of helminth transmission to humans. Poor environmental sanitation and personal hygiene facilitate the spread and transmission of STH. Jember is a district where the majority of the population lives in rural areas with poor sanitation access. This study aims to determine the correlation between soil contamination and incident of STH infection in Sukokerto Village, Sukowono District, Jember Regency. This cross-sectional analytic observational study was conducted from August 2022 to February 2023. The total of samples in this study was 44 fecal and soil around the house. The data obtained from the laboratory examination showed that the total fecal positive of STH was 11 or 25%, and soil was 13 or 29.5%. The results of the Chi-Square test analysis obtained ρ<0.05 (ρ=0.036, OR=4,457). The results showed a significant relationship between soil contamination and the incidence of STH infection in Sukokerto Village, Sukowo District, Jember Regency

Abstract

Tuberculosis (TB) and stunting remain serious health problems in Indonesia. Stunting can impact a child's ability to resist infections, including TB. Stunted toddlers are more vulnerable to contracting TB compared to those with normal nutritional status. This research aims to explore the relationship and influence of TB risk factors on the occurrence of TB in stunted toddlers. This research is an analytical descriptive research with a cross sectional design. The research sample consisted of 183 stunted toddlers from eight villages in the Rambipuji sub-district, Jember. The research procedures included interviews, direct observations, and TB examinations in children. Interviews were conducted with the parents/guardians of the child respondents. Observations and direct measurements were performed to determine the physical characteristics of the respondents' living environments, including household density, ventilation area, natural lighting, humidity, and room temperature. The diagnosis of TB in children was established based on a scoring table for childhood TB. From the research findings, 15 children tested positive for TB (8.2%). Bivariate analysis showed a value of p <0.05 for nutritional status, close contact, household density, ventilation, and natural lighting factors. Multivariate analysis revealed significant results for close contact (p=0.000; OR=39.563), household density (p=0.015; OR=9.659), and nutritional status (p=0.029; OR=6.718) as risk factors. In conclusion, it can be inferred that the risk factors associated with TB occurrence in stunted toddlers include nutritional status, close contact history, household density, ventilation, and natural lighting. The factors influencing TB occurrence in stunted toddlers are close contact history, household density, and nutritional status. Keywords: risk factor, stunted toddler, tuberculosis

Abstract

Obstructive sleep apnea (OSA) is a breathing disorder during sleep that can cause obstruction to the flow of breathing with characteristics such as collapse of the upper airway which can cause breathing to stop, either completely (apnea) or partial (hypopnea). Based on a study of taxi drivers in Jakarta, it was found that 52,5% of the sample had OSA. One of the main factors for OSA is obesity. Based on The American Academy of Sleep Medicine (AASM) recommends weight loss through lifestyle modifications (eg applying diet) as a treatment option for AHI improvement in OSA. The purpose of writing this article is to prove that adopting a diet can reduce the apnea hypopnea index (AHI) of OSA. The method in this study is a systematic review and meta-analysis using secondary data derived from PubMed, Science Direct, and Springer databases published from 2019 to 2022.. A total of six randomized controlled trial (RCT) articles were investigated by meta-analysis The weighted mean difference in AHI (-6,77 event/d with 95% CI: -13,42 to -0,1) significantly favoured diet over control arms. Based on the results of a systematic review and meta-analysis of six articles, the application of a diet is proven to reduce AHI scores in OSA patients.

Abstract

Abstrak. Cryptosporidium spp. adalah parasit intestinal yang secara global ditularkan melalui air (waterborne diseases), dengan banyak kejadian wabah di dunia yang dilaporkan terkait dengan sumber air konsumsi. Mayoritas penyakit ini tidak bergejala (asimptomatis) pada orang dewasa dengan rute penularan dari orang-ke-orang, hewan-ke-orang, melalui air dan makanan. Namun infeksi ini menyebabkan diare kronis hingga malnutrisi pada kelompok rentan yaitu balita dan merupakan faktor risiko terjadinya stunting.  Salah satu media transmisi Cryptosporidium spp. adalah air bersih yang dikonsumsi dan digunakan sehari-hari. Tujuan penelitian adalah untuk menganalisis risiko sumber air bersih yang digunakan sehari-hari terhadap infeksi Cryptosporidium spp. pada balita stunting secara spasial di Kabupaten Jember. Penelitian ini dilakukan pada populasi balita stunting di Kecamatan Kaliwates, Panti, Rambipuji dan Sukorambi Kabupaten Jember menggunakan desain cross sectional. Analisis spasial moran index dan nearest neigbor index (NNI) digunakan untuk mengetahui pola persebaran infeksi Cryptosporidium spp. terhadap suatu wilayah. Uji chi-square dilakukan untuk mengetahui hubungan faktor risiko sumber air  bersih  dengan infeksi Cryptosporidium spp. Hasil penelitian menunjukkan bahwa 18 dari 528 (3,41%) balita stunting diketahui terinfeksi Cryptosporidium spp. Nilai moran index menunjukkan adanya pola persebaran mengelompok (clustered) dengan autokorelasi positif di Kecamatan Sukorambi sedangkan daerah lainnya memiliki pola yang acak (random). Hasil NNI di Kecamatan Sukorambi menunjukkan pola yang acak, sedangkan 3 kecamatan lain menunjukkan pola menyebar (dispersed). Jenis sumber air bersih menunjukkan korelasi terhadap infeksi Cryptosporidium spp. Pola spasial infeksi Cryptosporidium spp. di Kecamatan Sukorambi dan korelasinya dengan jenis sumber air bersih ini menunjukkan bahwa pola infeksi ini cenderung mengelompok (clustered) karena penggunaan sumber air bersih yang sama pada penduduk di kecamatan ini yaitu sumber mata air alami yang digunakan bersama-sama seluruh warga, meskipun jarak antar penggunanya tidak berdekatan atau acak sesuai hasil NNI. Di 3 kecamatan lain, pola spasial cenderung menyebar (dispersed) karena penggunaan sumber air yang berbeda dan tidak digunakan secara bersama-sama. Kesimpulan, infeksi Cryptosporidium spp. cenderung meningkat pada sumber air bersih yang digunakan secara bersama-sama. Perlu edukasi pada kelompok masyarakat agar mengolah dulu air yang digunakan sebelum dikonsumsi untuk mengurangi risiko penyebarannya.Abstract. Cryptosporidium spp . are intestinal parasites that are transmitted worldwide by water(waterborne disease), with many of the reported outbreaks in the world associated with sources of drinking water. Most cases of the disease are asymptomatic in adults, and transmission is person-to-person, animal-to-person, waterborne, and foodborne. However, the infection causes chronic diarrhea and malnutrition in vulnerable children under the age of five and is a risk factor for stunting. One of the modes of transmission of Cryptosporidium spp . is through clean water, which is consumed and used daily. The study aimed to spatially analyze the risk of daily clean water sources on Cryptosporidium spp. infection among stunted children in Jember Regency. This study was conducted on a population of stunted young children in Kaliwates, Panti, Rambipuji and Sukorambi sub-districts of Jember Regency using a cross-sectional design. The Moran and NNI index were used to determine the distribution pattern of infection in a region. Chi-squared test was conducted to determine relationship between risk factors of clean water source and Cryptosporidium spp. It was found that 18 out of 528 (3.41%) stunted infants were known to have Cryptosporidium spp. infection. The Moran index value shows a clustered distribution pattern with positive autocorrelation in the Sukorambi sub-district, while the other areas show arandom pattern. The results of the NNI in Sukorambi sub-district show a random pattern, and 3 other sub-districts show adispersed pattern. The spatial pattern of Cryptosporidium spp . infection in Sukorambi subdistrict and its correlation with the type of clean water source shows that this infection pattern tends to cluster because the population in this subdistrict uses the same clean water source, natural springs, which are shared by all residents, although the distance between users is not close or random according to NNI results. In the other three sub-districts, the spatial pattern tends to be more dispersed due to the use of different water sources that are not shared. In summary, there is a tendency for the incidence of Cryptosporidium spp. to increase in shared water supplies. There is a need to educate community groups to treat the water they use prior to consumption in order to reduce the risk of its spread.Submitted: 2024-01-22  Revisions:  2024-09-11 Accepted: 2024-09-25 Published: 2024-09-25

Abstract

Background: Intestinal protozoan infection is a problem faced by the global community at all ages. In toddlers, it can cause problems in the form of decreased nutritional status, which is often found in developing countries such as Indonesia. The purpose of this study was to determine the correlation between intestinal protozoa infection and the nutritional status of toddlers.Methods: An observational study with a cross-sectional approach was conducted in October–December 2022 on 45 children aged 12–59 months in Sucopangepok Village, Jelbuk District, Jember Regency, East Java, Indonesia using, consecutive sampling techniques and a total sample size. Nutritional Status was measured based on body weight to body length using the WHO Anthropometric Calculator. Stool examination used the direct smear method and modified Ziehl-Neelsen staining. Data was analyzed using the Cramer's V test. The p-value less than 0.05 was considered statistically significant.. Results: The incidence of wasted children was 15.6% and severely wasted was 2.2%. Intestinal protozoan infection had an incidence of 15.6%. The species detected were Giardia lamblia (6.7%), Cryptosporidium parvum (6.7%), and Blastocystis hominis (2.2%). Statistical analysis showed there was no correlation between intestinal protozoan infection and nutritional status (p= 0.441; r = 0.191).Conclusions: There is no correlation between intestinal protozoan infection and the nutritional status of toddlers. However, comprehensive collaboration between the government and the community needs to be improved, as well as healthy lifestyles for toddlers which also need to be encouraged to overcome nutritional problems in children under five  old and prevent intestinal protozoa infections.

Abstract

Intestinal protozoa infections are still a major health problem in worldwide. The prevalence of intestinal protozoa infections are relatively high in countries facing lack of safe drinking water and lack of suitable sanitation facilities. Lack of sanitation facilities, open defecation, and contamination of environmental feces can make water quality worse, both in terms of physically, chemically, and biologically. Physical water quality is poor when the household water used daily does not meet the standard parameters of the physical water quality standard. The purpose of this study was to determine the relationship between physical water quality and intestinal protozoa contamination in household water in Ajung District, Jember Regency. This type of research is an observational analytic study with a cross sectional research design. The research method used is the correlation method, namely the relationship between physical water quality and intestinal protozoa contamination in household water. The population in this study is household water in Ajung District, Jember Regency. Data analysis consisted of univariate analysis to see the distribution and percentage of temperature, total dissolves solid, color, odor, and intestinal protozoa contamination in household water, and then bivariate analysis using the Chi-square test to analyze physical water quality and intestinal protozoa contamination. The conclusion is there is a relationship between physical water quality and intestinal protozoa contamination in household water.
