Dental Hygienists' Attitudes Toward the Obese Population.

To explore dental hygienists' attitudes toward the obese population and to determine whether there are differences in attitudes among those with different self-reported body images. The study population was dental hygienists whose email addresses were in the database of the California Dental Hygienists' Association (CDHA). CDHA distributed the electronic message containing study information, informed consent, and a link to the survey.

Nutrient intake, serum lipids and iron status of colligiate rugby players.

Background: There are two main playing positions in rugby (backs and forwards), which demonstrate different exercise patterns, roles, and physical characteristics. The purpose of this study was: 1) to collect baseline data on nutrient intake in order to advise the athletes about nutrition practices that might enhance performance, and 2) to compare serum lipids, lipoproteins, apolipoproteins (apo), lecithin:cholesterol acyltransferase (LCAT) activity, and iron status of forwards and backs.

Methods: The sporting group was divided into 18 forwards and 16 backs and were compared with 26 sedentary controls.

Physical activity, high-density lipoprotein cholesterol subfractions and lecithin:cholesterol acyltransferase in dialysis patients.

Background/aims: Although a low level of high-density lipoprotein cholesterol (HDL-C) is an independent risk factor for atherosclerotic heart disease, the mechanism of HDL-C abnormality in hemodialysis (HD) as well as peritoneal dialysis (PD) patients is not fully understood. The purpose of this study was to investigate the relationship of physical activity with HDL-C subfractions and lecithin:cholesterol acyltransferase activity in HD and PD patients.

Methods: Thirty-five HD and 26 PD patients were studied.

Physiological responses of simulated karate sparring matches in young men and boys.

The purpose of this study was to investigate the duration of each series of offensive and defensive techniques and the cardiovascular, metabolic, and perceptual responses during 2- and 3-minute bouts of simulated karate sparring. Six young men (age, 18-20 years) and 6 boys (age, 16-17 years) participated in this study. We formed 3 pairs of men and 3 pairs of boys to create a demanding competitive environment.
