Background: Data from racially and ethnically diverse US boys are needed to determine ages of onset of secondary sexual characteristics and examine secular trends. Current international studies suggest earlier puberty in boys than previous studies, following recent trend in girls.
Methods: Two hundred and twelve practitioners collected Tanner stage and testicular volume data on 4131 boys seen for well-child care in 144 pediatric offices across the United States.
Objective: The objective of this study was to assess parental knowledge and understanding of growth charts.
Methods: An online survey was conducted with 1000 parents selected to be demographically representative of the US population. Questions explored awareness of, knowledge of, and attitudes toward growth monitoring, as well as the ability to interpret growth chart data.
Background: Few studies have systematically assessed the reliability of pubertal markers; most are flawed by limited numbers of markers and ages studied.
Aim: To conduct a comprehensive examination of inter-rater reliability in the assessment of boys' sexual maturity.
Subjects: Eight pairs of practitioners independently rated 79 consecutive boys aged 8-14 years.
Objective: To examine current knowledge about the general public's comprehension of growth charts.
Methods: A literature search was carried out to identify and analyze the findings of studies that have examined the extent to which non-healthcare professionals comprehend the information presented by growth charts.
Results: Few studies have examined how well parents understand growth charts.
