Cancer prevention: what is energy balance?

submitted by: mdanderson
What is energy balance? It may sound like a strange term, but it basically means equalizing the amount of calories you take in with how much you burn through exercise, metabolism and body processes. Since obesity is one of the leading causes of cancer, Carrie Daniel-MacDougall, Ph.D., M.P.H. and Susan Schembre, Ph.D., R.D., both assistant professors in Cancer Prevention and Population Sciences at MD Anderson Cancer Center, study behaviors and biological processes associated with linking...

Being Overweight or Obese Is Associated with Lower Prevalence of Anemia among Colombian Women of Reproductive Age

submitted by: kasiek
Overweight and micronutrient deficiencies have manifested in the same individuals. This study investigated the association among iron deficiency (ID), anemia, and weight status among nonpregnant Colombian females aged 13-49 y (n = 3267). Data from the 2005 National Survey of the Nutrition Situation were used. The prevalence of ID (plasma ferritin <12.0 ?g/L; individuals with CRP >0.012 g/L excluded) and anemia (altitude-adjusted hemoglobin <120 g/L) was estimated separately. The...

Television, Adiposity, and Cardiometabolic Risk in Children and Adolescents

submitted by: amandastaiano
Background: It is largely unknown how TV use relates to depot-specif?c adiposity or cardiometabolic risk in children. Purpose: To examine relationships between having a TVin the bedroom and TV viewing time with total fat mass, abdominal subcutaneous and visceral adiposity, and cardiometabolic risk in children and adolescents. Methods: A cross-sectional study of 369 children and adolescents aged 5–18 years was conducted (2010 –2011; analysis 2011–2012). Waist circumference;...

Effects of energy-restricted high-protein, low-fat compared with standard-protein, low-fat diets: a meta-analysis of randomized controlled trials

submitted by: tom_witches
Background: It is currently unclear whether altering the carbohydrate-to-protein ratio of low-fat, energy-restricted diets augments weight loss and cardiometabolic risk markers. Objective: The objective was to conduct a systematic review and meta-analysis of studies that compared energy-restricted, isocaloric, high-protein, low-fat (HP) diets with standard-protein, low-fat (SP) diets on weight loss, body composition, resting energy expenditure (REE), satiety and appetite, and...

Social Media Delivered Sexual Health Intervention: A Cluster Randomized Controlled Trial

submitted by: sheana
Design: Cluster randomized trial; data collected in 2010-2011; analyzed in 2011-2012 Setting/Participants: Individuals (seeds) recruited in multiple settings (online, via newspaper ads and face-to-face) who were asked to recruit up to three friends, who in turn recruited additional friends, extending three waves from the seed. Seeds and waves of friends were considered networks and exposed to either intervention or control condition. Intervention: Exposure to Just/Us, a Facebook page...

Energy intake and expenditure during sedentary screen time and motion-controlled video gaming

submitted by: LIZ_LYONS
BACKGROUND: Television watching and playing of video games (VGs) are associated with higher energy intakes. Motion-controlled video games (MC) may be a healthier alternative to sedentary screen-based activities because of higher energy expenditures, but little is known about the effects of these games on energy intakes. OBJECTIVE: Energy intake, expenditure, and surplus (intake - expenditure) were compared during sedentary (television and VG) and active (MC) screen-time use. DESIGN: Young...

Effect of alginate supplementation on weight loss in obese subjects completing a 12-wk energy-restricted diet: a randomized controlled trial

submitted by: mekr@life.ku.dk
Background: Acute studies with alginate-based preloads suggested that these strong gelling fibers may induce increased feelings of satiety and reduce energy intakes. However, the long-term efficacy and safety of alginate supplementation on body weight regulation are lacking. Objective: The primary aim of the study was to investigate the effects in subjects of alginate supplementation in conjunction with energy restriction (2300 kcal/d) on loss of body weight and fat and, second, on...

Greater whole-grain intake is associated with lower risk of type 2 diabetes, cardiovascular disease, and weight gain

submitted by: sarachacko
Whole-grain and high fiber intakes are routinely recommended for prevention of vascular diseases; however, there are no comprehensive and quantitative assessments of available data in humans. The aim of this study was to systematically examine longitudinal studies investigating whole-grain and fiber intake in relation to risk of type 2 diabetes (T2D), cardiovascular disease (CVD), weight gain, and metabolic risk factors. We identified 45 prospective cohort studies and 21...

Differential gene expression in adipose tissue from obese human subjects during weight loss and weight maintenance

submitted by: tekn-ada
Background: Differential gene expression in adipose tissue during diet-induced weight loss followed by a weight stability period is poorly characterized. Markers of these processes may provide a deeper understanding of underlying mechanisms. Objective: We aimed to identify differentially expressed genes in human adipose tissue during weight loss and weight maintenance after weight loss. Design: RNA from subcutaneous abdominal adipose tissue from 9 obese subjects was analyzed by using a...

Role of Video Games in Improving Health-Related Outcomes

submitted by: brianprimack
Context: Video games represent amultibillion-dollar industry in the U.S. Although video gaming has been associated with many negative health consequences, it also may be useful for therapeutic purposes. The goal of this study was to determine whether video games may be useful in improving health outcomes. Evidence acquisition: Literature searches were performed in February 2010 in six databases: the Center on Media and Child Health Database of Research, MEDLINE, CINAHL, PsycINFO, EMBASE,...
