Investigating the association between parental educational status and offspring obesity risk using the Japan Environment and Children's Study
Authors' conclusion
Lower educational status in both parents was associated with overweight/obesity among 4-year-old children in Japan. Public policies might target parents with lower education to prevent childhood obesity.
