This study addressed the assessment of anthropometric characteristics and body composition of primary school children. The study aimed to determine age and sex related differences in children aged 7 and 8 years, which could be used to assess the health status of children and to monitor the trend of their growth and development. The study included 1520 students (814 second-grade students and 706 third-grade students; 772 boys and 748 girls). The participants were measured for body height and weight, body mass index, body fat percentage, fat mass, and fat-free mass. The results indicated that there were significant differences between boys and girls in body height and weight, fat percentage, body mass index, and fat-free mass (p <.05), whereas there was no difference in fat mass. Apart from the fat percentage, there are significant differences between seven-and eight-year-old children in all other measured variables. The obtained values of anthropometric characteristics and body composition of children are in accordance with the world trends. The differences between the sexes and the generations of children that have been identified are probably due to genetic predisposition, but also to the conditions in which they grow up.

Abstract: Stages of growth and development in children are affected by various internal and external factors, some of which have a greater impact than others. Among internal factors, the most important one is the genetic factor which includes disposition, gender, race, etc. However, during phases of growth and development in children, it is important to know what is the body condition of the child as a system, and the functionality of each subsystem. That is because the functioning of each internal subsystem depends to a certain degree on the impact of external factors such as living conditions, body activity, season, hygiene and nutrition. The goal of this research was to verify the presence of any statistically significant differences in anthropometric body characteristics of Montenegro and Kosovo primary school students, in relation to their age. The respondents' sample was comprised of 600 primary school male students from Montenegro and Kosovo aged 13, 14 and 15 years old. ...

In a cross-sectional study of growth, 5, 260 healthy children of both sexes from Zagreb (Croatia) aged 2 to 18 years were measured. Six transversal body dimensions were studied: biacromial, transverse chest, antero-posterior chest, biiliocristal, bicondylar humerus and bicondylar femur diamters. A significant increase in body diameters is observed until 14 to 15 years in girls and until 16 years in boys, showing that girls had 1 to 2 years shorter period of growth. Compared to boys of the same age, they achieved larger amounts of final transversal size of bones throughout the whole growth period. The most pronounced example was the knee diameter that in girls attained 95% of adult size already at the age of 10 years. In both genders, the adult size is achieved earlier in widths of the extremities than those of the trunk. The studied transversal body segments showed different growth dynamics, which is gender-specific. While sexual dimorphism in pelvic and shoulder diameters emerged with pubertal spurt, gender differences in chest and extremities’ diameters started early in life. In all ages, boys had larger chest, elbow and knee diameters. In pubertal age, boys gained significantly larger biacromial diameter (from the age of 13 years on) while girls exceeded them in biiliocristal diameter (from 10 to 14 years). The findings of gender differences were compared to those reported for other European populations and their growth patters discussed with a comparative viewpoint

The aim of this study was to evaluate sex-specific differences of anthropometric varibales that were used as indicators of nutritional status in Macedonian children aged 5. The study included 226 (113 boys and 113 girls) Macedonian children aged 5. We selected 5 anthropometrical parameters to measure (body weight, height, mid upper arm circumferences-MUAC, skinfolds thickness triceps–SFTr and subscapular-SFSc) and in addition according to the standard formulas we calculated: weight-for-age (BW), height-for-age (BH), body mass index-for-age (BMI) midupper-arm circumference-for-age (MUAC) and skifolds thikness (SFTr-for-age, SFSc-for-age). In general results have shown sex-specific differences in the examined parameters (BH, BW, BMI) in favour of the boys, with exception of skin-folds thickness that were higher in girls. Values of the 50th percentile in boys were as follows: 21 kg for BW, 115cm for BH, 15.48 kg/m2 for BMI, 15.5 cm for MUAC, 7mm for SFTr and 4.1mm for SFSc. The values ...
Sex differences in morphological dimensions in twelve-year-old children from Imotska krajina
Collegium antropologicum, 2009
The aim of the study was to identify and compare morphological characteristics of 12-year-old male and female children from Imotska krajina. The structure of a set of 23 morphological space variables were determined in a sample of 75 male and 67 female children by use of factor analysis for each sex in separate. Factor structure showed two basic superior latent dimensions responsible for directly measurable manifestations of morphological parameters in both male and female children. One of these two dimensions behaved as a general mechanism of growth and development, whereas the other showed a bipolar pattern. Bipolarity was almost exclusively determined by adipose tissue on one pole, and by skeletal longitudinal growth on the opposite pole. Rotation of the main components to varimax position yielded two morphological dimensions that were well balanced in both sexes (slightly better in girls); besides the predominant increase in adipose tissue, one of these dimensions was also respo...

In a cross-sectional study of growth, 5,155 children (2,591 females, 2,564 males) from the town of Zagreb (Croatia) were measured. Four traits of linear dimensionality (stature, sitting height, arm and leg lengths) were studied in the age span of 3 to 18 years. A significant average annual increase of all four anthropometric parameters were observed up to 14 and 15 years of age in girls and 16 years of age in boys, showing that girls had a shorter growing period. In the prepubertal period until 9 years of age, gender differences were negligible. At the age of 10, boys were overgrown by girls in all parameters due to the earlier onset of puberty in girls. The growth gains for girls, when compared with those for boys, show a different pattern across variables. The female growth advantage remained in a two years period for the limbs length, but in a three year period for stature and the longest, for 4 years, for sitting height. The male predominance in size had an onset at the age of 1...
Anthropometrical Status and Gender Differences at 12 Years of Age
Sport Mont Journal, 2015
The aim of this study is to verify the current anthropometrical status of the pupils of the age 12, as well as to compare it with the standards of raising in accordance with the WHO standards. In the study were included 62 pupils (42 male and 20 female). The anthropometric tests were done in height, weight, biacromial and elbow breadth, subcutaneous adipose tissue at the : suprailiac skinfold; subscapular skinfold; triceps skinfold, as well as the abdominal circumference. The results showed that there was a heterogenic distribution of results, especially in the body weight, where the distribution between the minimal and maximal results is 28-70 kg, with the average 43, 14 ± 9, 78 of standard deviation with the male pupils, while with the female pupils was noticed more homogenous group and the standard deviation was significantly lower than with the female pupils in all variables. The findings show that almost in all measured variables female pupils are more developed at this age, es...

The study included 50 participants of the preschool age, (Males=25; Age=6.21±0.44SD and Females=25; Age=6.49± 0.65SD) from Novi Sad with the aim of determining the existence of differences in the area of morphology. In accordance with the aim of the research, the measuring of morphological characteristics (body height, body mass, medium thorax circumference, stretched forearm circumference, stretched upper arm circumference) was conducted. By applying a multivariate analysis of variance it was determined that there were statistically significant differences (p = 0.00) in the morphological space. The individual analysis ascertained the differences for Medium thorax circumference, Medium forearm circumference and Medium upper arm circumference in favour of the boys. The differences in these variables caused by sexual dimorphism are statistically significant.

The purpose of the present study was to evaluate changes in main anthropometric parameters such as height, body mass, and body circumferences (chest, upper arm) in different age groups from childhood to adulthood in healthy females in Latvia and to determine the active growing age periods and the impact of tobacco use on anthropometric parameters. We provided a health well-being questionnaire concerning lifestyle and tobacco use. In the present study, we assessed the body mass index (BMI) values to identify body mass index-defined overweight and obesity. The levels of the body mass index exceeded the standard data only in a small number of the examined persons. Body composition data and the body mass index are used as an index of obesity as a standard practice by many clinicians according the recommendations of health authorities as a basis for health behaviour and physical activities to preserve physical and mental health. A significant correlation has been previously reported between anthropometric characteristics, physical activity and health capacity. The study data were collected with the participants' informed consent. Statistical analysis was performed using a statistics program. The body mass index is the respondents' major characteristic which describes the physical condition and nutrition level in any age group. Tobacco use by the mother during the pregnancy period has an influence on the child's body mass and body mass index values that were fixed for girls in the 1st and 2nd
