Factors affecting the occurrence of acute otitis media during the first year of life
Insights
This study investigated infectious diseases in children, focusing on acute otitis media. Key factors influencing its development include siblings, daycare, breastfeeding duration, and prematurity.
Area of Science:
- Pediatrics
- Infectious Diseases
- Epidemiology
Background:
- Infectious diseases pose a significant health challenge in early childhood.
- Acute otitis media is a common childhood infection requiring further investigation into its determinants.
Purpose of the Study:
- To identify factors influencing the development of infectious diseases, specifically acute otitis media, in infants.
- To analyze the association between various environmental and demographic factors and the incidence of acute otitis media.
Main Methods:
- A regional birth cohort of 5,356 infants was followed from birth.
- Infants were assessed at 3, 6, and 12 months for acute otitis media episodes and other health and environmental factors.
- Data collected included breastfeeding duration, siblings, daycare type, parental smoking, pets, and other illnesses.
Main Results:
- Two-thirds of infants experienced no acute otitis media episodes.
- The median age for the first episode was eight months.
- Approximately 10% of infants had recurrent acute otitis media (≥3 episodes) in the first year.
- Significant associations were found with number of siblings, daycare type, infant sex, breastfeeding duration, maternal socioeconomic status, and prematurity.
Conclusions:
- Several factors are significantly associated with the occurrence of acute otitis media in infants.
- Understanding these determinants can inform strategies for prevention and management of childhood infectious diseases.
Abstract:
A regional birth cohort of 5,356 infants was enrolled into a follow-up study in order to investigate the determinants of the development of infectious diseases in children. The infants were examined at three months, six months and twelve months of age by the physicians at the well-baby clinics. At these occasions the number of episodes of acute otitis media in the infants, the duration of breast-feeding, the number of siblings, the type of day care, parental smoking, the presence of animal pets at home and the number and type of other illnesses than otitis were registered. Two thirds of the infants had no episodes of acute otitis media. The median age for the first episode of acute otitis media was eight months. About 10% of the infants had experienced recurrent otitis media (three episodes or more) during their first year of life. Significant associations were found between the occurrence of acute otitis media and the number of siblings, the type of day care, the sex of the infant, the duration of breast feeding, maternal socioeconomic status and prematurity.
