Introduction: The mechanisms of the onset of pubertal development are not fully understood so far. Any information about correlates of puberty may hence be useful to generate and examine hypotheses about this issue. Methods: We investigated the relationships between singing activity of children and vocal parameters during the pubertal mutation of the voice in a cross-sectional case-control study . Eighty-seven children regularly singing under professional conduct and 97 children without singing activity beyond usual music lessons at school were included. Subjects were aged 10.5-16 years. Sociodemographic data and Tanner stages of puberty were also obtained. Results: Pubertal development was significantly more advanced in singers compared to age and sex matched non-singers (P=0.011). The adjusted mean difference of Tanner stages was 0.62 (95% CI: 0.14 to 1.11). In addition, possessing siblings was an independent predictor of less advanced puberty (P=0.034; difference -0.54 Tanner stages, 95% CI: -1.04 to -0.04). Discussion: Singing activity is possibly associated with an earlier onset of puberty. Relationships between singing and neurohumoral activity, as well as influences of the social environment may be discussed to be explanatory. However, these approaches are hypothetical so far, but they may inspire further investigations aiming at a better understanding of the matter.
