Screening for otitis media with effusion in Chinese schoolchildren: a pilot study

Area of Science:

• Pediatric Otolaryngology
• Epidemiology

Background:

• Otitis media with effusion (OME) is a frequent pediatric ear condition.
• Myringotomy with grommet insertion is the most common pediatric surgery globally.
• Prevalence data for OME in Chinese children is limited compared to Caucasian populations.

Purpose of the Study:

• To determine the point prevalence of OME in Hong Kong Chinese schoolchildren.
• To provide preliminary data for designing larger epidemiological studies in this demographic.
• To offer insights into screening methodologies for OME in Chinese children.

Main Methods:

• A pilot study was conducted on 255 Hong Kong Chinese schoolchildren aged 6–7 years.
• Otitis media with effusion (OME) prevalence was assessed using established screening criteria.
• Data collection focused on identifying children with OME within the study cohort.

Main Results:

• A point prevalence rate of 1.56% for OME was identified in the studied group.
• This prevalence is notably lower than figures reported in Western Caucasian children (2.3%–14%).
• The study highlighted potential challenges in population-based OME screening.

Conclusions:

• The prevalence of OME in Hong Kong Chinese schoolchildren appears lower than in Western populations.
• These preliminary findings are crucial for sample size calculations in future epidemiological studies.
• The study provides valuable insights into the epidemiology and screening of OME in Chinese children.
