“…Data from several studies using physical features of puberty (obtained from self-report or exams by health professionals) show adrenarche to occur later than gonadarche (Marceau et al, 2011; Paus et al, 2010; Shirtcliff et al, 2009). 1 But adrenal hormones rise earlier than gonadal hormones (reviewed in Styne & Grumbach, 2011), suggesting that physical features alone are insufficient to separate adrenarche from gonadarche, perhaps because adrenal hormone levels are insufficient to produce physical changes until gonadarche (Dorn et al, 2006; Wan, Deng, Archer, & Sun, 2012).…”

“…Progress on understanding mechanisms linking puberty to behavior depends on defining the aspects of puberty that matter and measuring them well, and this is the issue we address in this article. Puberty is not unitary (Styne & Grumbach, 2011), and it is likely that aspects affect psychological development in different ways. For example, psychological risk associated with early pubertal timing mediated by peers would be associated with an aspect of pubertal development apparent to others, whereas risk associated with development of limbic-mediated motivational systems would be associated with an early developing aspect.…”

Research on the role of puberty in adolescent psychological development requires attention to the meaning and measurement of pubertal development. Particular questions concern the utility of self report, the need for complex models to describe pubertal development, the psychological significance of pubertal timing versus tempo, and sex differences in the nature and psychological significance of pubertal development. We used longitudinal self-report data to model linear and logistic trajectories of pubertal development, and used timing and tempo estimates from these models, and from traditional approaches (age at menarche and time from onset of breast development to menarche), to predict psychological outcomes of internalizing and externalizing behavior problems, and early sexual activity. Participants (738 girls, 781 boys) reported annually from ages 9 through 15 on their pubertal development, and they and their parents reported on their behavior in mid-to-late adolescence and early adulthood. Self reports of pubertal development provided meaningful data for both boys and girls, producing good trajectories, and estimates of individuals’ pubertal timing and tempo. A logistic model best fit the group data. Pubertal timing was estimated to be earlier in the logistic compared to linear model, but linear, logistic, and traditional estimates of pubertal timing correlated highly with each other and similarly with psychological outcomes. Pubertal tempo was not consistently estimated, and associations of tempo with timing and with behavior were model dependent. Advances in modeling facilitate the study of some questions about pubertal development, but assumptions of the models affect their utility in psychological studies.

“…Pubertal development is associated with prominent changes in the body composition with attainment of more body fat in girls and more lean body mass, skeletal mass, and muscle mass in boys. 57 Moreover, these changes in body composition occur several years earlier in girls than in boys. 57 Without controlling for these developmental changes, the association between sleep duration and obesity may be biased.…”

“…57 Moreover, these changes in body composition occur several years earlier in girls than in boys. 57 Without controlling for these developmental changes, the association between sleep duration and obesity may be biased. Whether this relationship varies as a function of age and gender or is related to the pubertal growth needs further exploration.…”

Childhood obesity continues to be a major public health concern in the United States. This work reviews the current understanding of the relationship between sleep duration and obesity among children and adolescents. A systematic search was conducted for papers published between January 2000 and July 2013 using keywords: (sleep) and (overweight or obesity or obese or body mass index or BMI or adiposity or body fat or fat) and (children or child or youth or teen or pediatric or adolescent or paediatric or childhood or adolescence or boy or girl). Reference lists of relevant articles and reviews or meta-analysis articles were checked to identify additional studies. Only empirical work and longitudinal studies that focused on children and adolescents were included in this review. The search identified 22 longitudinal studies. The majority of the reviewed studies support the presence of an inverse relationship between sleep duration and obesity. However, in some studies the relationship was not significant in adjusted analyses. Differences as a function of age and gender were also noted. Despite more than a decade of research, the debate on the association between sleep duration and obesity continues. Further research with repeated assessments, valid objective measures, and better control of potential confounding variables is warranted.

“…There is a time lag between testosterone surge and physical development that occurs at puberty. An individual can have a surge in testosterone and yet the physical signs associated with this shift might not yet be present, especially in boys [Styne, 2007]. If we had sampled older adolescents (14-18 year olds), a correlation between pubertal status and testosterone levels would probably have been found, particularly among boys.…”

Androgen dynamics in the context of children's peer relations: an examination of the links between testosterone and peer victimization

Testosterone levels have been shown to decrease in the face of social defeat in several mammalian species. Among humans, the loss of social status has been studied primarily in the context of athletic competition, with winners having higher testosterone levels than losers. This study examined testosterone levels in relation to peer victimization (bullying) in a sample of 151 boys and girls aged 12-13. Statistically controlling for age and pubertal status, results indicated that on average verbally bullied girls produced less testosterone and verbally bullied boys produced more testosterone than their nonbullied counterparts. Similar trends were evident comparing social and physical bullying with testosterone. Sex differences are discussed in terms of empirically validated differences in coping styles, as girls tend to internalize, whereas boys tend to externalize, their abuse.
