Methods
Subjects were selected from the Bolton-Brush study participants who were examined with cephalometric radiographs at periodic intervals during childhood and adolescence. The specifics of the population have been described previously.12, 13 All subjects who were recalled during their adult years in 1992 and 1993 were included in the present study. The selection criteria were as follows: (1) all subjects had assessments of snoring at adult ages and (2) all subjects had cephalometric radiographs
Results
The sample consisted of 80 Bolton-Brush study participants who were recalled during their adult years (mean age, 64.9 ± 5.1 years). The 80 adult subjects were 52% male and 100% white. Of the 80 recalled subjects, only 45 had existing prepubertal (mean age, 4.5 ± 0.4 years; 56% male) records available; 76 had pubertal (mean age, 12.3 ± 0.4 years; 53% male) records available. Thus, the sample sizes for cross-sectional analysis were 45, 76, and 80 patients for prepubertal, pubertal, and adult time
Discussion
The present study is the first to investigate the changes in craniofacial factors in snorers and nonsnorers from childhood to adulthood; it was made feasible by the availability of the necessary records. An important finding was that H-MP distance was different between snorers and nonsnorers—a trend during childhood and adolescence but significant at the time of adult recall. The lack of significance during childhood and adolescence might have been caused by the small sample sizes, but the
