简要总结
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.
详细描述
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.

结局指标
主要结局
Chronic Suppurative Otitis Media
时间窗: Day1; This is a Cross-Sectional Survey and each participant will be assessed once. Therefore the outcome will be measured at data collection.
Chronic Suppurative Otitis Media will be defined as per the the World Health Organisation ear and hearing survey diagnostic criteria. To assign a diagnosis, tympanic membrane images and clinical data for each participant will be reviewed by two ENT surgeons who will assign a diagnosis. Disagreements will be resolved by a third 'tiebreaker'.
次要结局
- Hearing Impairment at more than 25 decibels hearing loss cutoff at 1000Hz, 2000Hz and 4000Hz(Day 1; This is a Cross-Sectional Survey and each participant will be assessed once. Therefore the outcome will be measured at data collection.)
