Prevalence and risk factors of disabilities among Egyptian preschool children: a community-based population study.

BACKGROUND

Child disability has significant implications on their well-being and healthcare systems.

AIM: This survey aimed to assess the magnitude of seven types of disability among Egyptian children aged 1 < 6 years and their socio-demographic, epidemiological, and perinatal predictors.

METHODS

A national population-based cross-sectional household survey targeting 21,316 children from eight governorates was conducted. The screening questionnaire was derived from the WHO ten-question survey tool validated for identifying seven disability categories.

RESULTS

The percentage of children with at least one disability was 8.1% as follows: speech/communication (4.4%), Mobility/physical (2.5%), Seizures (2.2%), Comprehension (1.7%), Intellectual impairment (1.4%), Visual (0.3%) and Hearing (0.2%). Age was not found to affect the odds of disability except for visual disability (significantly increased with age (AOR = 1.4, 95% CI:1.1-1.7). Male sex also increased the odds of all disabilities except visual, hearing, and seizures. Convulsions after birth significantly increased the odds of disability as follows: hearing (AOR = 8.1, 95% CI: 2.2-30.5), intellectual impairment (AOR = 4.2, 95% CI: 2.5-6.9), and mobility/physical (AOR = 3.4, 95% CI: 2.3-5.0). Preterm delivery and being kept in an incubator for more than two days after birth increased the odds for visual disability (AOR = 3.7, 95% CI: 1.1-12.1 & AOR = 3.7, 95% CI: 1.7-7.9 respectively). Cyanosis increased the odds of seizures (AOR = 4.7, 95% CI: 2.2-10.3). Low birth weight also increased the odds for all disability domains except for visual and hearing. Maternal health problems during pregnancy increased the odds for all types of disability except hearing and seizures. Higher paternal education decreased the odds for all disabilities by at least 30% except for vision and hearing.

CONCLUSION

The study found a high prevalence of disability among Egyptian children aged 1-6 years. It identified a number of modifiable risk factors for disability. The practice of early screening for disability is encouraged to provide early interventions when needed.
