Official Title: Prevalence and Associations of Paediatric Chronic Suppurative Otitis Media and Hearing Impairment in a Rural District of Malawi: A Cross-sectional Survey
Brief Summary: This community-based cross-sectional survey will estimate the frequency and risk factors of Chronic Suppurative Otitis Media and Hearing Impairment in Children ages 4-6 years in the Chikwawa District. These data will be useful for service planning, disease prevention efforts and to guide future research in this field.
Detailed Summary:
Type of research study:
Cross sectional survey
Problem to be studied:
Chronic suppurative otitis media and hearing impairment are important causes of morbidity, affecting 4-10% of children throughout sub-Saharan Africa. Many of the causes of disease are preventable with simple interventions. There is significant variation in disease burden and causes between countries, and currently no data on the frequency and causes of disease in Malawi.
Previous studies suggest poverty, crowding, paternal smoking and indoor cooking all increase the risk of developing chronic suppurative otitis media. The associations with use of an efficient cookstove have not been studied. The causes of childhood hearing impairment vary significantly by region and include otitis, other infections and cryptogenic causes.
Objectives:
- Estimate the prevalence of CSOM and other ear pathology in a population representative sample of 4-6 year-old children in a rural district of Malawi.
- Describe associations (including household use of an efficient cookstove) of CSOM
- Estimate the prevalence of hearing impairment defined by screening audiometry in a population representative sample of 4-6 year-old children in a rural district of Malawi.
- Describe associations of hearing impairment in a population representative sample of 4-6 year-old children in a rural district of Malawi.
Methodology:
A village level cluster survey in the Chi

Current Primary Outcome: Chronic Suppurative Otitis Media [ Time Frame: Day1; This is a Cross-Sectional Survey and each participant will be assessed once. Therefore the outcome will be measured at data collection. ]
Original Primary Outcome: Same as current
Current Secondary Outcome: Hearing Impairment at more than 25 decibels hearing loss cutoff at 1000Hz, 2000Hz and 4000Hz [ Time Frame: Day 1; This is a Cross-Sectional Survey and each participant will be assessed once. Therefore the outcome will be measured at data collection. ]
Original Secondary Outcome: Same as current
