BackgroundAcromegaly changes body composition (BC), but long-term gender differences have not been reported.ObjectiveTo evaluate BC in active and controlled acromegalic patients.Design and methodsClinical and biochemical variables and BC (by dual-energy X-ray absorptiometry) were evaluated in 60 acromegalic patients (19 active, 41 controlled) and 105 controls, matched for age and gender.ResultsAcromegalic males (n=24) had more total mass (89±13 vs 76.5±15.3 kg, P<0.001), lean body mass (LBM; 64.6±8.7 vs 56.4±5.8 kg, P<0.001), and bone mineral content (BMC; 2.9±0.5 vs 2.6±0.3 kg, P<0.05) than controls (n=33). Controlled male patients (n=14) had more total mass (89±14.7 vs 76.5±15.3 kg, P<0.05) and a trend to have more LBM (61.8±9.4 vs 56.4±5.8 kg, P=0.065) than controls. Only in active disease was a decrease in fat mass (FM) observed, compared with controlled patients and controls (males: 19.5±5.3 vs 27±6.2 and 25.9±4%, P<0.001; females: 30.3±6.7 vs 37.1±5.8 and 36.5±6.6%, P<0.01). In females, no further differences were observed. No differences in BMC were found between eugonadal and hypogonadal acromegalic patients, but in hypogonadal females, acromegaly appeared to prevent the BMC loss seen in hypogonadal postmenopausal controls. GH and IGF1 levels were negatively correlated with FM (males, P<0.05; females, P<0.001), but in the regression analysis GH was a predictor of FM only in women.ConclusionsControl of acromegaly reverts decreased FM in both genders; only in males more total mass and a trend for more LBM persist. The anabolic effect of GH on bone reverted in cured males, but persisted in females and appeared to override the bone loss of menopause.

Excess Postexercise Oxygen Consumption

The purpose of this study was to determine the influence of gender dimorphism and body composition on postexercise oxygen consumption during the rapid recovery phase. We compared the rapid-phase excess postexercise oxygen consumption (EPOC) in men and women matched for age (32.1 years), physical activity status, and maximal oxygen consumption (44.7 mL·kg–1·min–1), but not for body mass or fat-free mass (FFM). All subjects exercised for 1 h at 50% of their peak capacity. Although there were differences between genders in the magnitude of the absolute oxygen consumption and EPOC during the rapid phase of recovery, there were no differences found when EPOC was corrected for FFM. We conclude that the gender differences in the absolute O2 consumption and EPOC are related to the size of the FFM.

Abstract Cephalic indices is useful for evaluating racial and gender differences. In this study, we aimed to asses Gender Dimorphism Using cephalometry in the Iranian Population. Different variables like cranial length (CL), cranial width (CW), and cranial height (CH) were measured and cranial index (CI), cranial capacity (CC), and brain weight of 400 Iranian volunteers were calculated. Data were analyzed by means of SPSS 22.0. There were significant differences in the mean value of all nasofacial parameters (P<0.05). The highest sensitivity and specificity to predict the gender dimorphism were related to FL and FW (0.990 and 0.97) and (0.970 and 0.94), respectively. Considering the differences between male and female cranial structures, can be useful in forensic medicine and designing neurosurgical and ergonomic instruments in addition, to distinguish and discover the gender of the humans related to the many years ago.

Study Participants

ABSTRACT Objectives:  To evaluate age- and gender-related changes in the soft tissues, incisors, and gingival display during rest, speech, and posed smile. Materials and Methods:  A total of 265 participants (122 men, 143 women) ranging in age from 19 years to 60 years were recruited for this study. Participants were divided into one of the following four age groups: 19 to 24 years, 25 to 34 years, 35 to 44 years, and 45 to 60 years. Image capture was performed using standardized videographic methods. Each video produced pictures where measurements were performed: rest, speech, and smile positions. Results:  A statistically significant gender dimorphism was apparent in most of the variables. There was a significant increase in the upper lip length and lip commissures height with aging and more markedly in men. A greater exposure of mandibular incisor with increasing age was a feature in both genders. With increasing age there was a significant decrease in maxillary incisor display, especially for men. Conclusions:  After 25 years of age there is significant difference in the aging process between men and women. Gingival and maxillary incisor display during speech and smile is a youthful and feminine characteristic.
