    ABSTRACT: The association between fat distribution and Heath-Carter anthropometric somatotypes was studied in a sample of Basque children and youth aged 8–19 years. About mid-adolescence, mean somatotype of Basque males changed, diminishing in endomorphy and mesomorphy, and increasing slightly in ectomorphy. For the same period, reduced mesomorphy was the most striking change in the female mean somatotype; meanwhile, there was an increase in endomorphy and a decrease in ectomorphy. Two groups of fat distribution were identified: centripetal and peripheral. Centripetal fat increased with age in both sexes. Fat distribution groups showed the following characteristics: a) mean somatotypes of centripetal and peripheral subjects were significantly different; b) centripetal boys and girls were extreme endomorphs prior to adolescent somatotype change; c) centripetal girls showed high ratings of endomorphy after adolescence; d) mesomorphy was related to a centripetal fat distribution pattern in both sexes; e) using the BMI as a criterion of obesity, only 16.3% of centripetal males and 21.8% of centripetal females were classified as obese; f) obesity was absent among subjects with a peripheral pattern, except for one male showing an endomorphic-mesomorph somatotype; h) the obese showed extreme somatotypes with high endomorphy and mesomorphy, and minimal ectomorphy. © 1994 Wiley-Liss, Inc.

    ABSTRACT: Fat patterning of 110 adolescent males and 80 adolescent females was determined by principal components analysis of five skinfolds (triceps, subscaplular, iliac, abdominal and thigh). Densiometrically determined body fatness was employed to create two groups: obese (greater than 30% fat) and non-obese (less than 30% fat). Three fat patterning components emerged: trunk-extremity, upper-lower trunk and medial-lateral abdomen. The first two components accounted for 80% of the variance in fat distribution. The obese males and females demonstrate increased trunk fat patterning compared to the non-obese. Furthermore, obese males deposit increased trunk fat in the lower trunk while obese females deposit fat in the upper trunk.

    ABSTRACT: The distribution of subcutaneous fat at the triceps and subscapular skinfold sites is described for four groups of children living in Guatemala. These groups are high socioeconomic status (SES) children of Ladino (mixed Spanish and Indian) ancestry, high SES children of European ancestry, low SES Ladino children, and very low SES Indian children. The method of Healy and Tanner (1981) is used, employing regression and principal components analysis of log transformed skinfold values to divide "fatness" into two uncorrelated variables: size (amount of fat) and shape (fat pattern). Significant differences exist between groups in size, with lower SES groups having less fat than higher SES groups. No significant difference in fat pattern exists between the high SES Ladino and high SES European children. Significant differences do exist between the high SES groups and the low SES groups. The relative amount of subscapular fat increases from the high SES Ladinos and high SES Europeans, to the low SES Ladinos, to the very low SES Indians. In the high SES European and high SES Ladino samples, girls have significantly more arm fat than boys. There is no significant difference in fat patterning between boys and girls in the two low SES samples. Finally, the relative amount of subscapular fat tends to increase with age in all four samples. These results indicate that fatness and fat patterning are independent anatomical characteristics, SES influences fat patterning; low SES children of both Ladino and Indian ancestry show greater reductions in arm fat than in trunk fat compared to high SES children, sexual dimorphism in fat patterning is SES dependent.(ABSTRACT TRUNCATED AT 250 WORDS)
