Insights
Children with neurodevelopmental disabilities face early mortality risks from limited mobility, genetic factors, and hearing deficits. Comprehensive treatment at a child development center offers protection against these risks.
Area of Science:
- Pediatrics
- Developmental Pediatrics
- Public Health
Background:
- Neurodevelopmental disabilities (NDDs) present complex challenges for affected children and their families.
- Understanding factors influencing early mortality in this population is crucial for improving care and outcomes.
- Previous research has explored various risk factors, but a comprehensive analysis is needed.
Purpose of the Study:
- To identify significant risk factors associated with early mortality in children with NDDs.
- To compare risk factors between different control groups (age-matched and developmentally matched).
- To evaluate the protective effect of comprehensive treatment at a child development center.
Main Methods:
- Retrospective cohort study of 1000 children referred to a child development center (1975-1985).
- Analysis of mortality data for 81 deceased children compared to age-matched and developmentally matched control groups.
- Multivariate analysis to determine significant risk and protective factors.
Main Results:
- Low developmental quotient, restricted mobility, assisted feeding, and genetic etiology were risk factors for early mortality compared to age-matched controls.
- Restricted mobility, genetic etiology, and hearing deficit were significant risk factors compared to developmentally matched controls.
- Comprehensive treatment at the child development center was a significant protective factor against early mortality.
Conclusions:
- Key risk factors for early mortality in children with NDDs include mobility and feeding impairments, genetic etiology, and hearing deficits.
- Socioeconomic variables were not found to be significant predictors of increased mortality risk.
- Early and comprehensive intervention programs at specialized centers can significantly reduce mortality risk.
Abstract:
The aim of this study was to identify the risk factors for early mortality in children with neurodevelopmental disabilities. Of 1000 children who were sequentially referred to the same child developmental center over the period 1975-1985, 81 children died between the ages of 6 months and 22 years (mean, 8.04 years; 6.1 SD). A group of 81 age-matched children and another group of 81 developmentally and age-matched children also referred to the center served as comparison groups. Following multivariate analysis, low developmental quotient, restricted mobility, assisted feeding, and genetic etiology were risk factors for early mortality when compared to the age-matched group (P < .01). In comparison to the developmentally matched group, restricted mobility, genetic etiology, and hearing deficit were identified as significant risk factors (P < .01). Comprehensive treatment at the child development center was demonstrated to be a significant protective factor (P = .004). Socioeconomic variables were not significant in predicting an increased mortality risk in disabled individuals. In conclusion, in addition to mobility and feeding skills, a genetic etiology and hearing deficit are risk factors for early mortality, whereas socioeconomic variables are not. A comprehensive treatment program was found to be a protective factor.
