We tested the hypothesis that reductions in total body and abdominal visceral fat with energy restriction would be associated with increases in cardiovagal baroreflex sensitivity (BRS) in overweight/obese older men. To address this, overweight/obese (25 < or = body mass index < or = 35 kg/m(2)) young (OB-Y, n = 10, age = 32.9 +/- 2.3 yr) and older (OB-O, n = 6, age = 60 +/- 2.7 yr) men underwen...

This paper focuses on prevalence of nutritional status (Body Mass Index, BMI) in social groups in greater metropolitan São Paulo, in Southeastern Brazil. The population was stratified in four socioeconomic groups. Prevalence of malnutrition (BMI<18.5kg/m2), low body mass (BMI<20.0kg/m2), and overweight (BMI>25.0kg/m2) and obesity (BMI(30.0kg/m2) were calculated. Prevalence of malnutrition was 3...

OBJECTIVE The goal was to estimate the prevalence of overweight, obesity, underweight, and abdominal obesity among the adult population of Iran. RESEARCH METHODS AND PROCEDURES A nationwide cross-sectional survey was conducted from December 2004 to February 2005. The selection was conducted by stratified probability cluster sampling through household family members in Iran. Weight, height, an...

OBJECTIVE Environmental exposure to food sources may underpin area level differences in individual risk for overweight. Place of residence is generally used to assess neighbourhood exposure. Yet, because people are mobile, multiple exposures should be accounted for to assess the relation between food environments and overweight. Unfortunately, mobility data is often missing from health surveys....

Background and purpose: Research has shown that aging affects appetite and energy intake. The aim of this study was to investigate the protective effect of aerobic training (AT) and spirulina (SP) on Nesfatin-1 and Peptide YY (PYY) in overweight elderly men. Materials and Methods: In this clinical trial study, 32 overweight elderly men (age 57.50±4.84 years, Body mass index: BMI 26.90±2.85 kg/...

Observational studies suggest a longer duration of breastfeeding to be associated dose dependently with a decrease in risk of overweight in later life. The authors performed a comprehensive meta-analysis of the existing studies on duration of breastfeeding and risk of overweight. Studies were included that reported the odds ratio and 95% confidence interval (or the data to calculate them) of ov...

OBJECTIVE To compare overweight and lean subjects with respect to thermogenesis and physiological insulation in response to mild cold and rewarming. RESEARCH METHODS AND PROCEDURES Ten overweight men (mean BMI, 29.2 +/- 2.8 kg/m(2)) and 10 lean men (mean BMI, 21.1 +/- 2.0 kg/m(2)) were exposed to cold air for 1 hour, followed by 1 hour of rewarming. Body composition was determined by hydroden...

BACKGROUND In Chile, overweight and obesity are pressing issues in public health. AIM To identify individual, social and environmental factors that affect the likelihood of adolescents to become overweight or obese. MATERIAL AND METHODS We used physical condition data of a sample of 900 urban eighth grade students from Santiago, obtained in the 2011 National Study of Physical Education. Thi...

OBJECTIVE Our aim was to investigate the glutathione-disulfide system of antioxidant defense in men with different body mass index and infertility. METHODS 60 men with infertility were examined--30 with normal weight and 30 with overweight. 30fertile men were included in the control group. Hemolysate made from red blood cells was used as a materialfor study. The level of reduced (GSH) and oxi...
