“…At the onset of the study (1987), anthropometry was the best known technique, and also the cheapest, fastest and least invasive at our disposal. Our sample show slightly higher mean values of the sum of four skinfolds according to age than those reported in another study (Buckler, 1990), although there are no differences between our results and those of other Spanish studies (Herna Ândez et al, 1988;Sarrõ Âa et al, 1998). We did not ®nd signi®cant differences as regards age of pubertal onset in either boys or girls when comparing the SUM variable.…”

“…Our mean values of BMI are slightly higher than those recorded in other European studies (Buckler, 1990;Rolland-Cachera et al, 1982), a tendency also reported in another Spanish study (Herna Ândez et al, 1988). Our results indicate that in girls we found no signi®cant differences in the body mass of those who start puberty at 10, 11, 12 or 13 y; in contrast, the boys show progressively higher BMIs the later puberty begins (P`0.001).…”

“…We analyzed the data according to an equivalent moment of maturation in all groups: pubertal onset, a criterion that few authors have used (de Ridder et al, 1992). Studies that use PHV as their reference point for maturation do not describe the characteristics of their sample at pubertal onset (Buckler, 1990). …”

“…Provided observers are adequately trained, measuring subcutaneous body fat mass is an appropriate technique in studies with broad samples (van Lenthe et al, 1996;Buckler, 1990) and has proved to be a useful reference in epidemiological studies for the exploration of adolescents (Hammond et al, 1994). In addition, subcutaneous body fat mass measured in this way has been correlated with total body fat mass assessed using other methods (Durnin & Rahaman, 1967;Brook, 1971;Deurenberg et al, 1990; Figure 2 Mean fat mass evolution during the prepubertal period in each group of girls: (a) upper arm fat estimate (UFE); (b) sum of four skinfolds (SUM); (c) percentage of body fat (%BF).…”

Puberty begins with a characteristic subcutaneous body fat mass in each sex

Objective: To observe whether there exists a characteristic body fat mass at pubertal onset. Design: Longitudinal clinical follow-up (between ages of 10 and 15 y) with an annual visit in a sample of 469 children. They were grouped according to age of purbertal onset: boys with pubertal onset at the ages of 11 (n 59), 12 (n 88), 13 n 89) and 14 y (n 46), and girls with pubertal onset at the age of 10 (n 68), 11 (n 66), 12 (n 37) and 13 (n 16). Methods: Height, weight, upper arm circumference and four skinfold thicknesses were recorded annually. In boys testicular volume index was measured, and genital development was assessed on the Tanner scale; in girls mammary development was measured also using the Tanner scale. The sum of four skinfolds, body mass index, upper arm fat estimate and percentage body fat were calculated. Results: Boys presented a positive relation between the age of pubertal onset and body mass index (P`0.001), which was not observed in girls. Body mass index thus varied according to the onset of puberty in boys (P`0.001), but not in girls. The sum of four skinfolds, the upper arm fat estimate index and the percentage of body fat mass did not differ according to age of pubertal onset either in girls (P NS) or in boys (P NS). The characteristic adiposity of the puberty onset is progressively acquired during the previous years in all the groups. Conclusions: Puberty seems to begin with a characteristic subcutaneous body fat mass that is independent of the age of onset. This study supports the hypothesis of a close link between maturation and the development of an energy store in the form of adipose tissue in both sexes. Descriptors: body fat mass; onset of puberty; skinfolds

“…Following the Spanish study mentioned above (Sarría et al, 1998), we inferred the sum of the same four skinfolds that we measured in our study, finding the sum to be 28.9 mm in the group of boys aged 11-14 years. Buckler (1990) found that the average of the same sum of skinfolds between 12 and 14 years was approximately 24.2 mm. These values are lower than our figures at G2 (42.9 and 47.4 mm, in Spanish and Mexican whole samples, respectively); probably due to differences in the overall mean chronological age at the same maturation stage or perhaps due to a tendency of increasing adiposity in the young population.…”

Body fat at pubertal genital stage 2: a comparison between Spanish and Mexican boys

et al. 2008

View full text Add to dashboard Cite

Background/Objectives: To compare body fat mass at the same stage of pubertal maturation, genital stage 2 (G2), in a Spanish and in a Mexican sample of boys. Subjects/Methods: Data from Spain (n ¼ 177) were from a previous longitudinal clinical follow-up and data from Mexico (n ¼ 91) from a cross-sectional study. Subjects were grouped according to the presence of G2 at similar ages. Spanish sample was divided into boys with G2 at age 12 (n ¼ 60), 13 (n ¼ 74) and 14 (n ¼ 43). In Mexican sample, 23 boys were at G2 at 12 years, 38 at age 13 and 30 at 14 years. Height, weight, upper arm circumference and four skinfold thicknesses were recorded. Genital development was assessed (Tanner scale). Sum of four skinfolds (SUM), body mass index (BMI), percentage of body fat (%BF) and extremity/trunk skinfold ratio (ETR ¼ (triceps þ biceps)/(subscapular þ suprailiac)) was calculated. Results: When comparing subjects with different ages at G2 from the same country, or with the same age at G2 from different countries, no significant differences were found in adiposity variables (%BF, SUM), nor in BMI. Nevertheless, there were differences in body fat distribution: ETR was higher in Spanish boys (Po0.001), because of their greater triceps skinfold thickness (P ¼ 0.013), and due to the greater trunk fat stores in Mexican boys (Po0.01, subscapular and suprailiac skinfolds). Conclusions: There is a subcutaneous fat mass store characteristic of G2 in boys, which is not only independent of age, but is also observable in two different populations.
