Insights
Congenital clubfoot prevalence in China remained stable between 2001-2010, with variations observed across regions and genders. This study analyzed 4,233 cases, finding no significant trend over the decade.
Area of Science:
- Epidemiology
- Pediatrics
- Public Health
Context:
- Congenital clubfoot is a common birth defect with significant implications for child health.
- Understanding its prevalence trends and characteristics is crucial for public health initiatives.
- Data from China's birth defects monitoring program (2001-2010) provides a valuable resource for epidemiological analysis.
Purpose:
- To investigate the prevalence and epidemiological characteristics of congenital clubfoot in China from 2001 to 2010.
- To identify any trends in congenital clubfoot prevalence over the study period.
- To examine regional and gender-based disparities in congenital clubfoot occurrence.
Summary:
- A total of 4,233 cases of congenital clubfoot were identified among 8,273,382 births, yielding a prevalence of 5.12 per 10,000 births.
- No significant increasing or decreasing trend in prevalence was observed during 2001-2010 (P > 0.05).
- Statistically significant regional (West, Middle, East; South, North) and gender-based (male vs. female) differences in prevalence were found (P < 0.05).
Impact:
- This study provides critical epidemiological data on congenital clubfoot in China, highlighting regional and gender disparities.
- Findings can inform targeted public health interventions and resource allocation for managing this condition.
- The data suggests a higher prevalence in the Chinese population compared to international data, warranting further investigation.
Objective:
To understand the trend of prevalence of congenital clubfoot and its epidemiological characterisitics in China during 2001 to 2010.
Methods:
The data of the perinatal children with congenital clubfoot from 2001 to 2010 in the birth defects monitoring program were collected and analyzed, and the perinatal children were defined from the pregnancy of 28 weeks to postnatal 7 days, including live births, fetal deaths and stillbirths. SPSS16.0 software was used to analyze the data.
Results:
A total of 4,233 cases were identified with congenital clubfoot among 8 273 382 births, with a prevalence of 5.12/10(4). There was no increasing trend or decreasing trend on the prevalence of congenital clubfoot to be found in China during 2001 to 2010 (chi2 = 2. 43, P > 0.05). The prevalence of congenital clubfoot in urban and rural areas was 4.90 and 5.43 per 10 000 births respectively. The prevalence of congenital clubfoot in male and female babies was 5.31 and 4.3 per 10,000 births respectively. The prevalence of congenital clubfoot in west, middle and east region was 7.00, 4.52 and 4.27 per 10,000 births respectively. The prevalence of congenital clubfoot in south and north region was 5. 82 and 4. 34 per 10,000 births respectively. The difference between them is statistically significant (P < 0.05). The distribution of affected area between male and female was not significantly different (chi2 = 1.74, P < 0.05).
Conclusion:
There was no increasing or decreasing trend on the prevalence of congenital clubfoot to be found in China during 2001 to 2010. The prevalence of congenital clubfoot in China was found with regional differences and gender differences. The prevalence of congenital clubfoot in Chinese population is greater than foreign populations.
