Variation in Sequences of Age a t Peak Height Velocity and Age at Peak Weight Velocity

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...

Peak Weight and Height Velocity to Age 36 Months and Asthma Development: The Norwegian Mother and Child Cohort Study

BACKGROUND The immediate postnatal period is the period of the fastest growth in the entire life span and a critical period for lung development. Therefore, it is interesting to examine the association between growth during this period and childhood respiratory disorders. METHODS We examined the association of peak weight and height velocity to age 36 months with maternal report of current as...

The effect of prepubertal calcium carbonate supplementation on the age of peak height velocity in Gambian adolescents1234

BACKGROUND Limited evidence suggests that calcium intake before puberty influences adolescent height growth and the timing of puberty. Such an effect might be particularly marked in populations in whom low calcium intake, stunting, and delayed puberty are common. OBJECTIVE The objective was to test whether 12 mo of calcium supplementation at age 8-12 y to increase intakes toward international...
