Children in China are experiencing a rapid increase in the prevalence of obesity, which is associated with hypertension. To compare the effect of body fat on blood pressure (BP) with that of the normal physical growth, we compared BP levels in Chinese children with different body fat levels. In the present population-based study, 13 972 children in the highest-skinfold-thickness-quartile group ...

OBJECTIVES Cross-species comparisons show that high extrinsic mortality favors the evolution of "faster" life histories. There is interest in applying this principle to human life history plasticity, based on the idea that psychosocial stressors that correlate with extrinsic mortality accelerate reproductive pace. Most prior studies have been conducted in settings in which psychosocial stressor...

We studied the relationship between physical fitness and blood pressure in 228 school children. The data were collected as part of the Loma Linda Child-Adolescent Blood Pressure Study. Systolic and diastolic blood pressures were lower in children above average fitness than in children below average fitness among preadolescent and adolescent boys and girls. On multivariate analysis, adjusting fo...

The effects of an artificial diet on growth were examined in a controlled trial on 43 patients with cystic fibrosis. 28 patients received the diet for 12 months. Comparison was made between their growth before, during, and after dietary treatment. Growth changes were also assessed in 15 other patients who received a conventional diet. Artificial dietary treatment led to some improvement in heig...

In recent studies, a relationship between both low body fat and low thicknesses of selected skinfolds has been demonstrated for running performance of distances from 100 m to the marathon but not in ultramarathon. We investigated the association of anthropometric and training characteristics with race performance in 63 male recreational ultrarunners in a 24-hour run using bi and multivariate an...

Congenital anomalies of the lids and inner canthi are not uncommon. However, superior epiblepharon, an exaggerated palpebral skinfold overhanging the upper lid, is a rare congenital deformity in Caucasians, possibly transmitted as a dominant hereditary characteristic (Duke-Elder, I964). The patient described in this report is of unusual interest in that the superior epiblepharon did not become ...

Background: Skinfold thicknesses have long been considered important and valid measurements of subcutaneous fat. Nevertheless, there are no current skinfold reference data for US children and

PURPOSE The purpose of this study was to determine the effects of increasing the volume of weight-training from one to three sets upon body composition and muscular strength. METHODS Sixteen male weight-trainers volunteered to act as subjects and were randomly assigned to one of two training groups. Supervised weight-training targeting the upper body was conducted three times per week for eig...

The relation between breast-feeding and plasma cholesterol level in adult life was examined in a longitudinal study of a sample of people born in 1946. One hundred and seventy-two subjects whose breast-feeding history had been recorded during infancy were examined when they were 32 years old. Women who had been breast-fed had significantly lower mean plasma cholesterol than women who had been b...
