“…One sample includes 18 late-maturing girls with short parents (menarche >13.7 years, midparent stature <162.5 cm) followed longitudinally in the Wroclaw Growth Study of youth in southwestern Poland, 1961 to 1972. 28,29 The other sample includes 27 American girls classified as short, normal, slow-maturing children. The girls are from 6 longitudinal studies that date to the 1930s and have a stature at or below the 10th percentile of US reference data and an SA at least 1 SD less than CA.…”

“…First, short-, normal-, late-maturing youth from the combined samples for six major longitudinal studies in the US were defined as having heights less than the tenth percentiles of the US growth charts for at least two successive examinations between 3 and 18 years of age, SA at least one standard deviation less than CA, and free of disease [50]. Second, late-maturing youth with short parents from the Wrocław Growth Study (Poland) were defined by a difference between SA and CA in the lowest tertile at 12 years of age in girls and 14 years of age in boys in the respective longitudinal samples and a mid-parent height in the lowest tertile for girls and boys, respectively, in the longitudinal samples (Koziel S, personal communication for girl’s data) [51]. Third, youth from nine European pediatric clinics with idiopathic short stature that were defined by a height below two standard deviations of population-specific means and absence of detectable causes [52].…”

Role of Intensive Training in the Growth and Maturation of Artistic Gymnasts

et al. 2013

Short stature and later maturation of youth artistic gymnasts are often attributed to the effects of intensive training from a young age. Given limitations of available data, inadequate specification of training, failure to consider other factors affecting growth and maturation, and failure to address epidemiological criteria for causality, it has not been possible thus far to establish cause–effect relationships between training and the growth and maturation of young artistic gymnasts. In response to this ongoing debate, the Scientific Commission of the International Gymnastics Federation (FIG) convened a committee to review the current literature and address four questions: (1) Is there a negative effect of training on attained adult stature? (2) Is there a negative effect of training on growth of body segments? (3) Does training attenuate pubertal growth and maturation, specifically, the rate of growth and/or the timing and tempo of maturation? (4) Does training negatively influence the endocrine system, specifically hormones related to growth and pubertal maturation? The basic information for the review was derived from the active involvement of committee members in research on normal variation and clinical aspects of growth and maturation, and on the growth and maturation of artistic gymnasts and other youth athletes. The committee was thus thoroughly familiar with the literature on growth and maturation in general and of gymnasts and young athletes. Relevant data were more available for females than males. Youth who persisted in the sport were a highly select sample, who tended to be shorter for chronological age but who had appropriate weight-for-height. Data for secondary sex characteristics, skeletal age and age at peak height velocity indicated later maturation, but the maturity status of gymnasts overlapped the normal range of variability observed in the general population. Gymnasts as a group demonstrated a pattern of growth and maturation similar to that observed among short-, normal-, late-maturing individuals who were not athletes. Evidence for endocrine changes in gymnasts was inadequate for inferences relative to potential training effects. Allowing for noted limitations, the following conclusions were deemed acceptable: (1) Adult height or near adult height of female and male artistic gymnasts is not compromised by intensive gymnastics training. (2) Gymnastics training does not appear to attenuate growth of upper (sitting height) or lower (legs) body segment lengths. (3) Gymnastics training does not appear to attenuate pubertal growth and maturation, neither rate of growth nor the timing and tempo of the growth spurt. (4) Available data are inadequate to address the issue of intensive gymnastics training and alterations within the endocrine system.Electronic supplementary materialThe online version of this article (doi:10.1007/s40279-013-0058-5) contains supplementary material, which is available to authorized users.

Obesity and the clustering of cardiovascular disease risk factors in 14-year-old children

Although overweight and obesity in childhood are related to risk factors of cardiovascular (CVD), most studies have examined these relationships separately. Internal cut-points were used to examine the relation of overweight (>85th and <=90th percentile) and obesity (>90th percentile) to risk factor clustering in a sample of 2731 14-yearold children from Lower Silesia, Poland, examined crosssectionally in 1996-97. All subjects went through anthropometric and blood pressure measurements, and fasting serum levels of lipid, lipoproteins and glucose were estimated. All risk factor (>90th percentile) prevalence increased greatly at higher levels of Body Mass Index (BMI) (kg/m2). Nearly every second obese child had elevated systolic blood pressure and every third child had elevated serum levels of triglycerides. Among overweight boys 24.7% were found to have at least one risk factor, whereas among obese boys every fourth had at least one risk factor. 25% overweight girls and nearly 18% obese girls showed at least one risk factor. Standardized odds ratios for associations between overweight and obesity, and risk factor clustering, indicated that obese boys were 4.8 times more likely to have an elevated level of at least two factors; the probability increasing to 16.1 in the case of three and more factors in comparison to their lean peers. Obese girls showed more then a 7 time higher probability of having three and more risk factors in relation to their lean peers.
