The effect of aging on energy regulation remains controversial. We compared the effects of underfeeding on changes in energy expenditure and respiratory quotient in young normal weight men and women [YNW, age 25.7 +/- 3.2 y(SD), body mass index (BMI) 23.1 +/- 1.6 kg/m(2)], young overweight men and women (YOW, age 26.1 +/- 3.5 y, BMI 27.7 +/- 2.1 kg/m(2)) and older (OLD) men and women (age 68.4 ...

BACKGROUND Chile has probably experienced Latin America's fastest nutritional transition, as evidenced by very low rates of stunting, but the country shows a high prevalence of obesity in most population groups. OBJECTIVE The aim was to assess the existence of a double burden of nutritional problems in Chile on the basis of available data. DESIGN Secondary analyses were conducted on data co...

Abstract Aim The bidirectional association between obesity and depression seen in adults is not clearly established adolescents. aim of this study was to investigate the longitudinal body mass index (BMI), depressive symptoms interactions bullying victimization BMI, taking gender differences into account. Subjects methods In a Swedish county, self-reported victimization, BMI from 1729 adolescen...

BACKGROUND Obesity is associated with multiple diseases. Bariatric surgery is the most effective therapy for severe obesity that can reduce body weight and obesity-associated morbidity. The metabolic alterations associated with obesity and respective changes after bariatric surgery are incompletely understood. OBJECTIVE We comprehensively assessed metabolic alterations associated with severe ...

BACKGROUND The association of excess body weight across a lifetime with pancreatic cancer has not been examined extensively. OBJECTIVE We determined the association for body mass index (BMI) at different ages and adiposity duration and gain with incident pancreatic adenocarcinoma in the NIH-AARP Diet and Health Study cohort. DESIGN Participants aged 50-71 y completed questionnaires at basel...

Could calculus on graphs have emerged by the time of Archimedes, if function, graph theory and matrix concepts were available 2300 years ago? 1. Single variable calculus Calculus on integers deals with functions f (x) like f (x) = x 2. The difference Df (x) = f (x) = f (x + 1) − f (x) = 2x + 1 as well as the sum Sf (x) = x−1 k=0 f (k) with the understanding Sf (0) = 0, Sf (−1) = f (−1) are func...

We consider the equation y′′ = F (z)y (z ∈ C) with an entire function F satisfying the condition |F (z)| ≤ A exp ` |z|ρ ρ ́ (ρ ≥ 1, A = const > 0). Let zk(y), k = 1, 2, . . . be the zeros of a solution y(z) to the above equation. Bounds for the sums j X k=1 1 |zk(y)| (j = 1, 2, . . . ) are established. Some applications of these bounds are also considered.

AIMS/INTRODUCTION The goal of this study was to evaluate the effect of Roux-en-Y gastric bypass (RYGB) on hyperglycemia and gastrointestinal hormones in Chinese obese type 2 diabetic patients with body mass index (BMI) between 28 and 35 kg/m(2). MATERIALS AND METHODS A total of eight obese type 2 diabetes patients with BMI 28-35 kg/m(2) who underwent RYGB and 10 obese normal glucose tolerance...

OBJECTIVE To investigate whether overweight women are more likely to have a hysterectomy and whether hysterectomy leads to increased weight gain. METHODS Survey data of middle-aged women participating in the Australian Longitudinal Study on Women's health in 1996 (ages 45-50 y; n = 13,125), 1998 (n = 10,612), 2001 (n = 10,293), and 2004 (n = 9309) included self-reported height, weight, and hy...

BACKGROUND It is unclear which exposures may cause or modify the adverse effect of rapid weight gain on fat mass development in term children whose birth weight is appropriate-for-gestational age (AGA). OBJECTIVE To determine which intrauterine or postnatal exposures increase the risk of or modify the effect of rapid weight gain on body fat percentage (BF%) and body mass index (BMI) trajector...
