Childhood overweight and obesity, especially among migrant children, are current health problems in several European countries. In the present study the prevalence of overweight and obesity among migrant children from Turkey and the former Yugoslavia was documented and compared with that of Austrian children in Vienna. Anthropometric data from 1786 children were collected at the ages of 6, 10 and 15 years. Body mass was estimated by means of the body mass index and percentile curves were used to determine weight (...) status. The prevalence of overweight and obesity was found to be significantly higher among migrant children. Children and adolescents from the former Yugoslavia and Turkish girls exhibited especially high rates of overweight and obesity. Biosocial and cultural factors are discussed as causes of these observations. (shrink)

The present study analyzes body fat distribution, a well-known and important indicator of reproductive capability, in young women between 18 and 28 years of age (mean=23.3 years) suffering from secondary amenorrhea and therefore temporary infertility resulting from self-starvation. Body composition parameters estimated by means of dual energy x-ray absorptiometry and the fat distribution index, indicating body shape, were compared with those of healthy controls. Although members of the infertile, amenorrheic group exhibited dramatically low body weight and total amount of body (...) fat, and therefore a marked negative energy balance in comparison with the healthy controls, the sex-specific fat distribution patterns did not differ between infertile and fertile young women. In contrast, the lower the weight and total fat amount, the more gynoid the fat distribution, even in infertile women. This observation may be interpreted in an evolutionary sense: Our ancestors had to cope with frequent food shortages, even starvation, and therefore lengthy periods of negative energy balance. In addition to pregnancy and lactation, temporary infertility as a result of long-term negative energy balance was not an uncommon phenomenon in female life histories. Nevertheless, after a time of plenty, reproductive function recovered, and therefore the gynoid fat distribution patterns in temporarily infertile young women may be interpreted as signal of reproductive capability, which resumes after a time of surplus.

The impact of hysterectomy without oophorectomy and with no malignant purpose on body composition and postmenopausal weight gain was tested in 184 Viennese females aged between 47 and 57 years. Hysterectomized women were significantly heavier than those who experienced a spontaneous menopause. The amount of fat tissue, especially in the abdominal region, was significantly higher in hysterectomized women. Furthermore, they were reported to have experienced a significantly higher weight gain since menopause. No significant differences in bone mass were found. Psychological (...) stress factors and hormonal changes following hysterectomy are discussed as possible causes of these differences. (shrink)
