MONDAY, Oct. 22, 2018 (HealthDay News) — High childhood body mass index (BMI) is strongly correlated with slipped capital femoral epiphysis (SCFE), according to a study published online Oct. 22 in Pediatrics<\/i>.<\/p>\n
Daniel C. Perry, Ph.D., from the University of Liverpool in the United Kingdom, and colleagues used data from 597,017 children aged 5 to 6 years linked to a nationwide hospital admissions database to examine the strength of the association between SCFE and childhood obesity. Data were also examined for 39,468 children age 11 to 12 years.<\/p>\n
The researchers found that 75 percent of children with obesity at 5 to 6 years old remained obese at 11 to 12 years old. A strong biological gradient was seen between childhood BMI at 5 to 6 years old and SCFE; for each integer increase in BMI z score, the risk for disease increased by a factor of 1.7. Among children with the lowest BMI, the risk for SCFE was almost negligible. Compared with those with a normal BMI, those with severe obesity at 5 to 6 years old had a 5.9 times greater risk for SCFE; severe obesity at 11 to 12 years old was associated with a 17.0 times greater risk for SCFE.<\/p>\n
“The temporal relationship, dose response, and magnitude of the association build on the existing biological plausibility and findings in previous lower-quality studies to offer the strongest possible support for a causal relationship between childhood obesity and SCFE,” the authors write.<\/p>\n
