“…Self-assessments of Tanner stages of pubic hair development in boys and girls, genital development in boys, and breast development in girls were obtained every six months from ages 8 to 18 years by having each participant match his or her pubic hair/genital/breast development against a set of standardized photographs [14]. Each participant’s serial data permitted the identification of inconsistent or implausible classifications.…”

Objective To examine the relationship of the initial manifestation of pubertal development in children to anthropometric measurements recorded during the early childhood and adolescence. Methods The Fels Longitudinal study is an observational study of growth and development of healthy white children. A total of 109 boys and 75 girls with serial self-assessments of Tanner stages of genital/breast and pubic hair developments provided data for a longitudinal analysis with a linear mixed model. Results About 11.0% of boys and 22.7% of girls witnessed the appearance of pubic hair (adrenarche) prior to the onset of genital/breast growth (gonadarche/thelarche) and about 13.7% of boys and 22.7% of girls experienced the onset of gonadarche/thelarche prior to adrenarche. The remaining 75.3% of boys and 54.7% of girls were concordant for adrenarche and gonadarche/thelarche. During the first two years of life, boys and girls with earlier gonadarche and thelarche than adrenarche were found to have more rapid weight gain than those with earlier adrenarche than gonadarche/thelarche. During early childhood from age 2 – 7 years, those girls with early thelarche had higher body mass index (BMI) and waist circumference to height ratio (waist/height) than those with early adrenarche. In children of ages 8 – 20, girls with early gonadarche had higher BMI z-scores than those with early adrenarche. Conclusion Girls with early thelarche and later adrenarche, have more rapid mean weight gain during the first two years of life, higher BMI and waist/height during early childhood, and higher BMI z-scores during adolescence. Boys with early gonadarche and later adrenarche experienced more rapid weight gain during the first two years of life than boys with early adrenarche and later gonadarche. In other words, girls with early thelarche are more likely to be triggered by early accumulation of fat mass than those with early adrenarche.

“…Comparison of measured anthropometric data of a child to the population average by utilizing growth charts is one of the basic methods for growth evaluation. Growth charts are an indispensable part of pediatric practice for their ease of use in assessing growth and development [19,20]. Anthropometric surveys carried out at regular intervals are important indicators of children's health and the most appropriate way to assess the nutritional and health status of the pediatric population [21,22].…”

Body Fat Mass, Percent Body Fat, Fat-Free Mass, and Skeletal Muscle Mass Reference Curves for Czech Children Aged 6–11 Years

2021

Background: Negative lifestyle trends are reflected in overweight and obese children, in which their lack of physical activity results in decreased muscle mass. This study aimed to define age- and sex-specific reference curves for body fat mass (BFM), skeletal muscle mass (SMM), fat-free mass (FFM), and percent body fat (%BF) in Czech children. Methods: Body composition was measured by segmental bioelectrical impedance (BIA, InBody 720). The research sample included 2093 children aged 6–11 years (1008 boys and 1085 girls). Only children whose parents provided informed consent were included. Statistical analysis was performed using SPSS v. 22. The statistical analysis was performed separately by age and sex. Anthropometric data were summarized as means and standard deviation. The percentile curves (P3, P10, P25, P50, P75, P90, and P97) of BFM, FFM, %BF, and SMM were calculated using the gamlss package in R 3.4.2 (R Foundation for Statistical Computing, Vienna, Austria). Results: This study developed age- and gender-specific percentile curves of SMM, FFM, BFM, and %BF for Czech children aged 6–11 years. During childhood, BFM and %BF increased in boys, peaking at approximately 11 years of age. Girls displayed a different pattern of age-related changes in BFM and %BF compared to that in boys. These parameters gradually increased during childhood. This pattern was also observed for SMM and FFM in both sexes. Conclusions: The purpose of this study was to serve as a reference to improve methods to evaluate body composition in Czech children and for comparison with studies worldwide.

Adolescent growth spurt

The adolescent growth spurt refers to the rapid increase in height and weight that begins with puberty, lasts throughout adolescence, and stops with the cessation of linear growth. The spurt precedes and follows a series of hormonal, physiological, psychological, and behavioral changes that turn juvenile males and females into reproductive adults. Its age of onset will vary by sex, and across populations, and children in developed nations have experienced a secular reduction since the second half of the nineteenth century. The adolescent growth spurt may be species specific and may have appeared with Homo sapiens sapiens approximately 125,000 years ago in Africa.
