“…It is base are the Qualitative changes in body composition, which occur at certain stages of girls development and characterized with different relation between the fractions of body mass. Our findings supported these of previous research, which found a different relation between fat, muscle and bone tissue during the different ontogenetic period (1,2,4,11,13,15,17,18,19,22,23,24).…”

“…More recently, these workers [10] have emphasised the importance of measuring fat distribution in children as a method of identifying those at risk from obesity and associated morbidity. Th e present study confi rms the fi ndings of American [1] and European [28,30] researchers that sexual dimorphism of fat patterning in children is present at 5-7 years of age. Our study shows that increased central body fat in girls but former study show that increased central body fat in children is related to adverse changes in lipid profi les [12], insulin metabolism [11] and blood pressure [39].…”

“…A tendency towards truncal/central fat distribution in children of prepubertal ages has been reported in the German [28], USA [1] and the Spanish population [30]. Since fat distribution plays a major role in both morbidity and mortality, it is important to examine the nature and timing of fat patterning in children.…”

Background: Obesity among school children has emerged considerably in the recent years with changing of life styles.Aim: The present study analyses the patterns of fat accumulation during childhood and adolescents.Subjects and methods: A Cross-sectional sample of 684 female and 687 male (total 1,371) Turkish children, aged 7-18 years, were selected randomly from schools, by the permission of the Turkish National Educational Ministry. The percentage of bodyfat (BF), the weight of fat mass (FM) and the fat free mass (FFM) in trunk, right and left leg, right and left arm (all in kg) were estimated.Results: The findings revealed a significant increase in BMI, BF, FFM, the trunk fat and the trunk muscle mass over the studied age periods in both sexes. The mean trunk FFM and trunk FM were higher in males than in the females. On the contrary, the mean trunk FM and whole body FM for females were higher than in males. During the years of adolescence FFM, as well as BF, increases in the males and the gains are considerably greater than noticed in the females, who accumulate more body fat.Conclusion: The present study generates the baseline data for undertaking future investigations on the obesity of the Turkish children.

“…Humans experience a brief period of preadolescent growth quiescence preceding the pubertal growth spurt, which corresponds temporally to the initiation of sexual maturation (Arfai et al, 2002;Braillon, 2003). This specific pattern is not observed in rats.…”

Systemic regulation of the cellular processes that produce endochondral elongation and endochondral mineralization during postnatal skeletal maturation are not completely understood. In particular, a mechanism coupling the decline of cellular activity in the bone microenvironment to the onset of sexual maturity remains elusive. The purpose of this study was to empirically integrate the dynamic progression of bone mineral accrual and endochondral elongation as a function of animal age in growing male and female Sprague-Dawley rats. We used serial dual-energy X-ray absorptiometry (DXA) and radiography to study the temporal progression of bone growth and mineral accrual from weaning to adulthood. We observed that skeletal maturation proceeds in a pattern adequately described by the Gompertz function. During this period of growth, we found that serum markers of osteoblastic bone formation declined with age, while osteoclastic bone resorption activity remained unchanged. We also report a slight lag in the age at inflection in the rate of bone mineral accrual relative to the rate of tibial elongation and that both endochondral processes eventually come to asymptotic equilibrium by approximately 20 weeks of age. In addition, we studied tibial growth plate histomorphometry at select time points through 1 year of age. We report that, despite the histologic persistence of physeal cartilage, very little proliferative or elongative activity was measured in this tissue beyond 20 weeks of age. Taken together, these data provide insight to the temporal coordination of postnatal endochondral growth processes.

Bone, Muscle, and Fat: Sex-related Differences in Prepubertal Children

Abstract: Together, these data indicate that sex is an important determinant of the morphology in humans well before the beginning of puberty.
