Determinants of Acute Otitis Media in Children: A Case-Control Study in West Java, Indonesia

Background and Objectives: Acute Otitis Media (AOM) is a leading cause of morbidity in children, characterized by fever, otalgia, and hearing loss. If untreated, AOM may progress to chronic complications requiring surgical management. Globally, factors such as allergies, environmental tobacco smoke, and nutritional deficiencies are well-established risk factors, but in Indonesia, particularly rural areas like Bandung Regency, limited awareness and data exacerbate the burden of disease. Smoking prevalence and low immunization rates further increase risks for AOM. Materials and Methods: This case-control study, conducted between September 2019 and February 2020 in Bandung Regency, evaluated risk factors for AOM in children aged 24-59 months. Data were collected through structured questionnaires, anthropometric assessments, and ENT examinations. A total of 168 AOM-positive and 367 AOM-negative children were recruited from primary healthcare facilities. Results: Multivariable analysis identified significant associations with AOM: allergic rhinitis (AOR 1.92), cigarette smoke exposure (AOR 1.79), stunted growth (AOR 1.48), and incomplete basic immunizations (AOR 1.77). These findings highlight the importance of addressing modifiable factors such as nutrition and immunization to reduce AOM incidence. Conclusions: The rhinitis allergy and exposure to cigarette smoke are among the well-established risk factors that our results validate. Additional research is necessary to validate if our findings involving two modifiable risk factors, stunted children and insufficient basic vaccination, may increase the risk of AOM.
