Insights
Cerebral palsy (CP) affects 1.9-2.8 per 1000 children in Taiwan, with higher prevalence in boys, low-income families, and rural areas. These findings highlight key risk factors for CP in the Chinese population.
Area of Science:
- Pediatrics
- Epidemiology
- Public Health
Background:
- Cerebral palsy (CP) is a significant developmental disorder affecting children.
- Understanding CP prevalence and associated risk factors is crucial for public health initiatives.
- Taiwan's healthcare data offers a valuable resource for epidemiological studies.
Purpose of the Study:
- To determine the annual prevalence of cerebral palsy (CP) in children under 7 years old in Taiwan.
- To investigate the association between socioeconomic status and CP prevalence.
- To identify demographic and geographic factors linked to CP in Taiwan.
Main Methods:
- Utilized data from the Taiwan National Health Insurance Research Database (2002-2008).
- Defined severe and total CP using catastrophic illness certificates and medical claims.
- Calculated annual CP prevalence per 1000 children aged under 7.
Main Results:
- Annual prevalence of total CP ranged from 1.9 to 2.8 per 1000 children; severe CP ranged from 1.1 to 1.4 per 1000.
- Boys had a 30% higher likelihood of CP (adjusted RR 1.3-1.4).
- Low family income (adjusted RR 5.1-6.4) and rural location were associated with higher CP prevalence.
Conclusions:
- CP prevalence in Taiwan is comparable to Western countries.
- Male sex, low income, and rural residence are associated with increased CP prevalence.
- Findings offer insights into CP epidemiology within the Chinese population.
Background:
The present study investigated the annual prevalence of cerebral palsy (CP) among children aged <7 years in Taiwan and the association between socioeconomic status and CP prevalence.
Methods:
Data from the Taiwan National Health Insurance Research Database for the 2002-2008 period were used in this population-based study. Severe and total CP were defined according to catastrophic illness certificate and medical claim records, respectively. The annual CP prevalence was calculated as the number of children with CP among all children aged <7 years.
Results:
From 2002 to 2008, the annual prevalence of total and severe CP ranged from 1.9 to 2.8 and from 1.1 to 1.4 per 1000 children, respectively. Boys were 30% more likely to have CP than girls [adjusted relative risk (RR) and 95% confidence interval (CI) ranged from 1.3 (1.2-1.4) to 1.4 (1.2-1.5)]. Low family income was associated with a higher CP prevalence [adjusted RR (95% CI) ranged from 5.1 (4.2-6.2) to 6.4 (5.4-7.6)]. The prevalence of CP in rural area was higher than that in urban or suburban areas. The mortality rate of severe CP ranged from 12.2-22.7 per 1000 children within the 7 years study period.
Conclusions:
The prevalence of CP in Taiwan is similar to that in Western countries. A higher prevalence of CP is associated with male sex, low income, and rural residential location. Our findings provide insights into CP epidemiology among the Chinese population.
