Anthropometric and somatotype characteristics of women with breast cancer / Características antropométricas y somatotipos de mujeres con cáncer de mama

Inconsistent data are available on the relation between breast cancer, adiposity, body size and somatotype. The aim of our study was to compare anthropometric characteristics, body composition and somatotype between breast cancer patients and healthy controls. Study group consisted of 106 breast cancer patients while control group consisted of 100 healthy women who underwent 29 anthropometric measurements. Women with breast cancer expressed more male anthropometric features like higher stature (160.75±6.91 vs. 158.17±4.89 cm, p=0.020), shorter trunk (sitting height in premenopausal: 84.94±5.07 vs. 88.50±3.84 cm, p=0.001 and postmenopausal women: 81.96±6.08 vs. 85.19±3.36 cm, p=0.001), narrower hips (29.20±3.78 vs. 32.24±1.78 cm, p=0.000), higher biepicondylar diameter of humerus (premenopausal: 6.64±0.71 vs. 6.31±0.42 cm, p=0.012; postmenopausal: 6.95±0.63 vs. 6.54±0.49 cm, p=0.000), larger upper- and forearm as well as upper thigh circumferences followed by lower biceps and higher thigh skinfold thicknesses. They also had significantly lower endomorphy (premenopausal: 5.84±1.78 vs. 6.55±0.96, p=0.027; postmenopausal: 6.89±1.52 vs. 7.37±0.86, p=0.035) and significantly higher ectomorphy (premenopausal: 2.05±1.30 vs. 1.41±0.99, p=0.018; postmenopausal: 1.06±0.90 vs. 0.68±0.56, p=0.007), as well as higher mesomorphy only in postmenopausal women (6.10±2.04 vs. 5.37±1.34, p=0.022). Most represented somatotype among breast cancer patients was endomorph-mesomorph while the most healthy controls were mesomorphic endomorph. Android body type increases the risk of development of breast cancer. Indicators of skeletal dimensions, muscle volume and peripheral adiposity had better predictive value over markers of central and overall adiposity.

La información en la literatura es variable sobre la relación entre el cáncer de mama, la adiposidad, el tamaño corporal y somatotipo de las mujeres. El objetivo de este estudio fue comparar las características antropométricas, la composición corporal y el somatotipo entre pacientes con cáncer de mama y controles sanos. El grupo de estudio consistió en 106 pacientes con cáncer de mama y el grupo de control de 100 mujeres sanas que se sometieron a 29 mediciones antropométricas. Las mujeres con cáncer de mama tenían mayor cantidad características antropométricas masculinas, tal como una estatura más alta (160.75±6.91 vs. 158.17±4.89 cm, p = 0.020), tronco más corto (altura sentada en premenopáusica: 84.94±5.07 vs. 88.50±3.84 cm, p = 0.001 y mujeres posmenopáusicas: 81.96±6.08 vs. 85.19±3.36 cm, p = 0.001), caderas más estrechas (29.20±3.78 vs. 32.24±1.78 cm, p = 0.000), mayor diámetro biepicondilar del húmero (premenopáusico: 6.64±0.71 vs. 6.31 ±0.42 cm, p = 0.012; posmenopáusica: 6.95±0.63 vs. 6.54±0.49 cm, p = 0.000), mayor circunferencia del antebrazo y la parte superior del muslo, bíceps inferiores y mayor grosor del pliegue de la piel del muslo. Además se observó una endomorfia significativamente menor (premenopáusica: 5.84±1.78 vs. 6.55±0.96, p = 0.027; posmenopáusica: 6.89±1.52 vs. 7.37±0.86, p = 0.035) y una ectomorfia significativamente más alta (premenopáusica: 2.05±1.30 vs. 1.41 .990.99, p = 0.018; posmenopáusica: 1.06±0.90 vs. 0.68±0.56, p = 0.007), así como una mayor mesomorfia solo en mujeres posmenopáusicas (6.10±2.04 vs. 5.37±1.34, p = 0.022). El somatotipo más representado entre las pacientes con cáncer de mama fue el endomorfomesomorfo, mientras que los controles más sanos fueron el mesomórfico endomorfo. Las características del cuerpo tipo androide aumenta el riesgo de desarrollar cáncer de mama. Los indicadores de dimensiones esqueléticas, volumen muscular y adiposidad periférica tuvieron un mejor valor predictivo sobre los marcadores de adiposidad central y general.

Somatotype characteristics of normal-weight and obese women among different metabolic subtypes.

BACKGROUND: Obesity is a well known risk factor for the development of metabolic abnormalities. However, some obese people are healthy and on the other hand some people with normal weight have adverse metabolic profile, therefore it can be assumed that there is a difference in physical characteristics amongst these people. The aim of this study was to establish whether there are somatotype differences between metabolically healthy and metabolically obese women who are obese or of normal weight. SUBJECTS AND METHODS: Study included 230 women aged 44.76 ± 11.21y. Metabolic status was assessed according to IDF criteria, while somatotype was obtained using Heath & Carter method. RESULTS: Significant somatotype differences were observed in the group of women with normal-weight: metabolically healthy women had significantly lower endomorphy, mesomorphy and higher ectomorphy compared to metabolically obese normal-weight women (5.84-3.97-2.21 vs. 8.69-6.47-0.65). Metabolically healthy obese women had lower values of endomorphy and mesomorphy and higher values of ectomorphy compared to 'at risk' obese women but the differences were not statistically significant (7.59-5.76-0.63 vs. 8.51-6.58-0.5). Ectomorphy was shown as an important determinant of the favorable metabolic profile (cutoff point was 0.80). CONCLUSION: We concluded that, in addition to fat mass, metabolic profile could be predicted by the structure of lean body mass, and in particular by body linearity.
