Background And Objective: Studies of the relationship of weight status with timing of puberty in boys have been mixed. This study examined whether overweight and obesity are associated with differences in the timing of puberty in US boys.
Methods: We reanalyzed recent community-based pubertal data from the American Academy of Pediatrics' Pediatric Research in Office Settings study in which trained clinicians assessed boys 6 to 16 years for height, weight, Tanner stages, testicular volume (TV), and other pubertal variables.
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.
