Growth and Pubertal Timing in Boys With Adult-diagnosed Celiac Disease: A Population-based Longitudinal Cohort Study.

There are few longitudinal data on whether childhood growth and pubertal timing may be impaired by adult-diagnosed celiac disease (CD). Through school health care records and national registers, we retrieved serial growth measurements on 37,672 Swedish boys born in 1945 to 1961, out of whom 72 (0.2%) were clinically diagnosed with CD as adults. Boys with, versus without, adult-diagnosed CD exhibited no appreciable mean differences in body mass index (BMI, kg/m) and height (cm) at ages 8 or 20 to 21 years (childhood BMI, 15.9 [CD] vs 15.7 [comparators]; childhood height, 129.1 [CD] vs 128.6 [comparators]; adult BMI, 21.3 [CD] vs 21.4 [comparators]; adult height, 180.7 [CD] vs 180.4 [comparators]). Neither did we observe any between-group differences in growth development during puberty nor in the timing of pubertal growth spurt (all P values ≥0.30). Conclusively, in this population-based longitudinal study, boys with adult-diagnosed CD had similar growth and pubertal timing as their peers.
