Contributions of incidence and persistence to the prevalence of childhood obesity during the emerging epidemic in Denmark.

ABSTRACT:

Background

Prevalence of obesity is the result of preceding incidence of newly developed obesity and persistence of obesity. We investigated whether increasing incidence and/or persistence during childhood drove the prevalence of childhood obesity during the emerging epidemic.

Methods

Height and weight were measured at ages 7 and 13 years in 192,992 Danish school children born 1930-1969. Trends in the incidence (proportion obese at 13 years among those not obese at 7 years) and persistence (proportion obese at 13 years among those obese at 7 years) across birth cohort periods (1930-41 with low stable prevalence of obesity, 1942-51 with increasing prevalence, 1952-69 with the higher, but stable prevalence) were investigated. Logistic regression was used to examine the associa
