Epidemiological study of congenital talipes calcaneovalgus
Insights
This study found talipes calcaneovalgus occurs in 4.2 per 10,000 births. Breech delivery and first-time mothers (primiparae) are identified as significant risk factors for this congenital foot malformation.
Area of Science:
- Pediatrics
- Medical Genetics
- Epidemiology
Background:
- Talipes calcaneovalgus is a congenital foot malformation.
- Understanding its incidence and risk factors is crucial for early intervention and prevention strategies.
Purpose of the Study:
- To determine the incidence of talipes calcaneovalgus in South American newborns.
- To investigate potential genetic and environmental risk factors associated with this condition.
Main Methods:
- Analysis of data from 671,494 live births in South American hospitals.
- Comparison of newborns with talipes calcaneovalgus to matched control groups.
- Statistical investigation of various risk factors including maternal and delivery characteristics.
Main Results:
- An incidence of 4.2 per 10,000 live births was observed for talipes calcaneovalgus.
- A higher proportion of females were diagnosed with the condition.
- Breech delivery and primiparous mothers were identified as significant risk factors.
Conclusions:
- Talipes calcaneovalgus has a specific incidence rate in the studied South American population.
- Maternal factors such as primiparity and delivery presentation (breech) are associated with increased risk.
- Further research into the etiology of talipes calcaneovalgus is warranted.
Abstract:
Among 671,494 children born in South American hospitals participating in the Collaborative Latin American Study of Congenital Malformations (ECLAMC), 284 had talipes calcaneovalgus, corresponding to an incidence of 4.2 per 10,000 live births. Genetic and environmental risk factors were investigated in the sample of malformed newborns with talipes calcaneovalgus and in matched control babies. An excess number of females was found among the newborns with talipes calcaneovalgus. Talipes calcaneovalgus patients did not differ from the matched controls in terms of ethnic groups, inbreeding coefficient, time between gestations or multiple births. However, the data suggested that breech delivery and primiparae mothers are higher risk factors for this newborn malformation.
