Tanner’s tempo of growth in adolescence: recent SITAR insights with the Harpenden Growth Study and ALSPAC

open access: yesAnnals of Human Biology, 2020
Background: James Tanner emphasised the “tempo” of growth, i.e. the adolescent spurt as summarised by its timing (age at peak velocity or APV) and intensity (peak velocity, PV).

Ages at peak height velocity in male soccer players 11–16 years: relationships with skeletal age and comparisons among longitudinal studies [PDF]

open access: yesBiology of Sport, 2023
Estimated ages at take-off (TO) and at peak height velocity (PHV) based on two models and maturity status based upon age at PHV and skeletal age (SA) were compared in a longitudinal sample of male soccer players.

SITAR-d: extending the SITAR growth curve model to allow for variability in post-pubertal velocity

open access: yesAnnals of Human Biology
Background The SITAR growth curve model with its three random effects is useful for summarising height growth in individuals and groups. However SITAR performs less well for weight which unlike height continues to change post-puberty.Aim To describe ...

Patterns of linear growth among children and adolescents living with HIV on antiretroviral therapy in Zimbabwe and Zambia [PDF]

open access: yesBMC Infectious Diseases
Background Adolescents with HIV (AWH) frequently exhibit impaired growth, which manifests as stunting and wasting. We studied trajectories in leg-length (appendicular), sitting (axial), and standing height among AWH on antiretroviral therapy (ART ...
