Modelling height in adolescence: a comparison of methods for estimating the age at peak height velocity

BACKGROUND Controlling for maturational status and timing is crucial in lifecourse epidemiology. One popular non-invasive measure of maturity is the age at peak height velocity (PHV). There are several ways to estimate age at PHV, but it is unclear which of these to use in practice. AIM To find the optimal approach for estimating age at PHV. SUBJECTS AND METHODS Methods included the Preece ...

Pubertal Gynecomastia Coincides with Peak Height Velocity

OBJECTIVE Pubertal gynecomastia (PG) occurs in up to 65% of adolescent boys. In this study, we investigated the relationship between the ages at which PG and peak height velocity occur in pubertal boys. METHODS This was a prospective study that was designed to detect PG within three months of its emergence. We examined one hundred and six boys who were followed for short stature and/or delaye...

Comparison of Best Regions for BMD Measurement Regarding the Age, Weight and Height of Postmenopausal Women

Osteoporosis is a major public health problem. Menopause provokes a decrease in bone mineral density (BMD) that causes postmenopausal osteoporosis. This study aimed to compare different regions for BMD measurement in postmenopausal women, with regarding to the effect of age, weight and height. 313 osteoporotic menopaused women  were classified in 1 of 3 categories on the basis of their age (50-...

Prepubertal height velocity references over a wide age range.

In order to correct height velocities for the confounders age and sex, SD scores can be calculated using the mean and the SD of the height velocity in the normal population. However, current methods are inappropriate for prepubertal children in the age range in which puberty occurs, because reference groups then consist of a mixed prepubertal/pubertal population. The mathematical infancy-childh...
