Prevention of intellectual and other disabilities: the Singapore experience

In Singapore, first level prevention, aimed at reducing the occurrence of disabilities, has included neonatal screening for glucose-6-phosphate dehydrogenase deficiency, a programme of universal vaccination, screening for congenital hypothyroidism, and improvements in obstetric and neonatal care. Non-specific measures, such as improved housing, better nutrition and higher standards of education, have also contributed to the reduction in serious illnesses that can potentially cause disabilities. Second level prevention, designed to limit or reverse a disability, has included a developmental screening programme carried out in the primary health care sector. Centralised multi-disciplinary developmental assessment clinics have been established to define better the disabilities and to advise on rehabilitation. An early intervention programme has been started, and special schools are being upgraded. Third level prevention, aimed at preventing a disability from becoming a handicap, has included the setting up of comprehensive rehabilitation programmes, provision of aids and appliances, vocational training, and job opportunities. The integration of the handicapped back into society is currently being promoted.
