There are few long-term studies on whether the adult-diagnosed celiac disease affects childhood growth and pubertal timing (CD). The researchers obtained serial growth measures on 37,672 Swedish boys born between 1945 and 1961 from school health care records and national registries, 72 of whom were clinically diagnosed with CD as adults. At ages 8 or 20 to 21 years, boys with adult-diagnosed CD had no substantial mean changes in body mass index or height; childhood height, 129.1 vs 128.6; adult BMI, 21.3 vs 21.4; adult height, 180.7 vs 180.4. They also found no between-group variations in growth development throughout puberty or the time of the pubertal growth spurt. 

In conclusion, boys with adult-diagnosed CD exhibited similar development and pubertal timing as their peers in this population-based longitudinal research.
