In 1973, DRF learned of the innovative longitudinal survey of child development started in Dunedin the year before. DRF immediately recognised the increased benefits of the study if ear and hearing problems were included. An enthusiastic response from the survey’s founder, Professor Phil Silva, ensured the not only were ear and hearing problems included in the survey, but Professor Silva also added his innovative skills to DRF as a board member.
By following more than 1000 children since their birth in 1972, this long-term study of every aspect of their health and development has provided original data on the progression and effects of otitis media. This study revealed that the early onset of chronic otitis media had serious adverse affects on speech articulation, reading skills, language development and classroom behaviour throughout these children’s school years and beyond.
