Hypothesis
Are prenatal exposures to PFOA and PFOS associated with behavioral or coordination problems in children at age 7?
Conclusion
Background levels of PFOA and PFOS are not associated with behavioral and motor coordination problems in childhood.
Supporting Evidence
- Maternal blood levels of PFOA and PFOS were measured around 8 weeks of gestation.
- Behavioral health and motor coordination were assessed using the Strengths and Difficulties Questionnaire and the Developmental Coordination Disorder Questionnaire.
- The study found no significant associations between PFC levels and behavioral problems or coordination disorders.
Takeaway
This study looked at whether chemicals from certain products affect kids' behavior. It found that these chemicals don't seem to cause problems.
Methodology
Data from the Danish National Birth Cohort was used, measuring maternal blood levels of PFOA and PFOS and assessing child behavior at age 7 using standardized questionnaires.
Potential Biases
Selection bias may have occurred as the children included appeared healthier than the general population.
Limitations
The study may not have been large enough to detect associations with clinical disorders like ADHD.
Participant Demographics
Mothers were primarily of higher socioeconomic status and had normal prepregnancy BMIs.
