title: Prevalence and Parental Risk Factors for Speech Disability Associated with Cleft Palate in Chinese Children-A National Survey.
abstract: Although the prevalence of oral clefts in China is among the highest worldwide, little is known about the prevalence of speech disability associated with cleft palate in Chinese children. The data for this study were collected from the Second China National Sample Survey on Disability, and identification of speech disability associated with cleft palate was based on consensus manuals. Logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs). A weighted number of 112,070 disabled children affected by cleft palate were identified, yielding a prevalence of 3.45 per 10,000 children (95% CI: 3.19-3.71). A history of speech disability in the mother (OR = 20.266, 95% CI 5.788-70.959,p< 0.0001), older paternal child-bearing age (OR = 1.061, 95% CI 1.017-1.108,p= 0.0065, per year increase in age), and lower parental education (maternal: OR = 3.424, 95% CI 1.082-10.837,p= 0.0363; paternal: OR = 2.923, 95% CI 1.245-6.866,p= 0.0138) were strongly associated with risk of speech disability associated with cleft palate in the offspring. Our results showed that maternal speech disability, older paternal child-bearing age, and lower levels of parental education were independent risk factors for speech disability associated with cleft palate for children in China. These findings may have important implications for health disparities and prevention.
