Timing of voice breaking in males associated with growth and weight gain across the life course.

ABSTRACT:

Background

In contrast to the many studies in females, there are few data in males on the relationships between childhood growth and weight gain and the timing of pubertal maturation and its relevance to adult body mass index (BMI) and body composition.

Methods

A total of 2008 males in the 1946 British Birth Cohort Study had assessment of pubertal status including voice-breaking status (no change, starting, or complete) at age 14 yr. These responses were related to growth measurements at birth (weight only) and at 2, 4, 6, 7, 11, 14, 20, 26, 36, 43, 53, and 60-64 yr. Body composition was assessed by dual-energy x-ray absorptiometry at 60-64 yr.

Results

Males with more advanced voice-breaking status at age 14 yr had similar birth weights compared with other males; they
