Abstract

Introduction: Environmental noise from transportation, especially railways, is a form of sound pollution that affects health both auditorily and non-auditorily. Homemakers, who spend most of their time at home, are particularly vulnerable to noise exposure. This study aimed to analyze differences in hearing thresholds, blood pressure, and habitual sleep efficiency among homemakers residing in areas with varying noise levels, as well as contributing individual, behavioral, and environmental factors. Methods: This was an analytical observational study with a cross-sectional design involving 60 housewives—30 from a noise-exposed area (Ambengan Selatan Karya) and 30 from a quieter area (Rusunawa Wonorejo). Data were collected through noise measurements using a Sound Level Meter, audiometric tests, blood pressure measurements, and questionnaires inspired by the Pittsburgh Sleep Quality Index (PSQI). Statistical analyses included the Independent T-Test to analyze the differences in environmental noise level, the Mann-Whitney test to analyze the differences of each dependent variable, and the chi-squared test to analyze the influences. Results and Discussion: Significant differences were found in environmental noise levels (p=0.021), right ear hearing thresholds (p=0.039), blood pressure (p=0.007), and sleep efficiency (p=0.040). No significant difference was observed in left ear hearing thresholds. Factors influencing right ear hearing thresholds included age and earphone use, age influenced blood pressure, while physical barriers affected sleep efficiency. Conclusion: High exposure to environmental noise may increase the risk of hearing loss, hypertension, and sleep disturbances.

Abstract

Introduction: The incidence of ARI in children under five in Balongsari Health Center saw a significant rise. The rise in ARI cases is attributed to air pollution, environmental contamination, and poor public hygiene. One of the causes of air pollution is the use of mosquito repellent. This study aimed to analyze risk factors associated with pollution sources, home physical conditions, and toddler characteristics related to ARI in the Balongsari Health Center area. Methods: This study uses quantitative approach with a case-control design, this study involved a sample of 50 toddlers in the case group and 50 in the control group, selected through simple random sampling. Data were collected via interviews and observation and analyzed using the Chi-Square test. The questionnaire covered toddler's characteristics, sources of indoor pollution, and physical household conditions. Temperature was measured with a thermohygrometer. Meanwhile, ventilation and room size were measured with a roll meter. Results and Discussion: Results indicated that mosquito repellent use was significantly associated with ARI (p = 0.010; OR = 4.000), along with physical conditions such as room temperature (p = 0.004; OR = 4.667), ventilation (p = 0.020; OR = 3.455), and household density (p = 0.032; OR = 3.286). Conclusion: These findings suggest that mosquito repellent selection, ventilation improvements, and breastfeeding practices play a crucial role in ARI prevention among toddlers in this area.
