Waist Measurements And BMI To Determine Body Weight Status
According to a study published Online First by Archives of Pediatrics & Adolescent Medicine, a JAMA Network publication, body mass index (BMI) together with waist measures (waist circumference, waist to height ratio) are connected with lipid and blood pressure evaluations among adolescents who are overweight or obese. At present, BMI is used to determine whether an adolescent is overweight or obese. However, as BMI is unable to differentiate between fat and fat-free body mass, the researchers decided to include waist circumference (WC) as well as waist to height ratio (WHtR: WC divided by height), in relation to BMI in order to assess the role of waist measures in the lipid and blood pressure evaluations of adolescents classified by BMI.
Pesticides Can Induce Morphological Changes In Vertebrate Animals
The world's most popular weed killer, Roundup® , can cause amphibians to change shape, according to research published in Ecological Applications. Rick Relyea, University of Pittsburgh professor of biological sciences in the Kenneth P. Dietrich School of Arts and Sciences and director of Pitt's Pymatuning Laboratory of Ecology, demonstrated that sublethal and environmentally relevant concentrations of Roundup® caused two species of amphibians to alter their morphology. According to Relyea, this is the first study to show that a pesticide can induce morphological changes in a vertebrate animal.
Higher Energy Density Diets Linked To Higher Body Weight
Strong and consistent evidence indicates that adults consuming a higher energy density (ED) diet have a higher body weight, whilst those who eat a relatively low ED diet experience weight loss and maintain their weight, whilst there is moderate proof that children and adolescents who eat higher ED diets are linked to higher weight. The study, published in the Journal of the Academy of Nutrition and Dietetics, consisted of systematical reviews and updates of the Dietary Guidelines for Americans 2010 recommendations to consume a low energy density diet.
