Objective: To explore the potential role of the endogenous peptide YY (PYY) in the long-term regulation of body weight and energy homeostasis. Research Methods and Procedures: Fasting and postprandial plasma PYY concentrations were measured after an overnight fast and 30 to 180 minutes after a standardized meal in 29 (21 men/8 women) non-diabetic subjects, 16 of whom had a follow-up visit 10.8 ± 1.4 months later. Ratings of hunger and satiety were collected using visual analog scales. Resting me...

Objective: Increased mRNA and activity levels of 11β-hydroxysteroid dehydrogenase type 1 (11βHSD1) in human adipose tissue (AT) are associated with obesity and insulin resistance. The aim of our study was to investigate whether 11βHSD1 expression or activity in abdominal subcutaneous AT of non-diabetic subjects are associated with subsequent changes in body weight and insulin resistance [homeostasis model assessment of insulin resistance (HOMA-IR)]. Research Methods and Procedures: Prospective a...

The in utero environment is a powerful risk factor for type 2 diabetes in offspring, but little is known about the risk conveyed by nondiabetic gestational glucose levels. This issue was explored in 911 nondiabetic Pima Indian mothers and 1,436 of their children. Associations were assessed in multivariate models between maternal third trimester glucose tolerance and indexes of body composition and glycemic control in their children. At parturition, the mothers’ ages ranged from 14 to 43 years. O...

: The hypothalamus has a major role in the control of food intake. However, neurotracing studies have shown that the hypothalamus receives input from several other regions of the brain that are likely to modulate its activity. Of particular interest to the understanding of human eating behavior is the possible involvement of the cortex. Using positron emission tomography (PET), we generated functional brain maps of the neuroanatomical correlates of hunger (after a 36-h fast) and satiation (after...

Obesity is a multifactorial disease associated with an increased risk of type 2 diabetes, coronary artery disease, cancer, and consequently, with a reduced length of life. Metabolic phenotypes of reduced energy expenditure have been associated with weight gain, but their contribution has been estimated to be relatively small. On the other hand, excessive food intake is likely to be the major determinant of positive energy balances and it is underlied by both non-conscious (homeostatic) and consc...

Background: Understanding the factors that contribute to physical inactivity in children is important because sedentary behavior strongly relates to metabolic disorders such as obesity and diabetes. Objective: We aimed to quantify the genetic and environmental influences on physical activity energy expenditure (PAEE) in 100 sex-concordant dizygotic (n = 38) and monozygotic (n = 62) twin pairs aged 4-10 y. Design: Resting metabolic rate (RMR) was assessed by using respiratory gas exchange, total ...

Abstract Objective Dietary calcium intake, especially from dairy products, may have a protective effect against obesity. This study aimed to determine if calcium intake is associated with body weight and adiposity in Pima Indians, an obesity-prone population. Research Methods and Procedures Subjects were 65 Pima Indian adults (35 men/30 women, age 33±8 years [mean±standard deviation]) participating in a study of eating behavior and 78 Pima Indian children (36 boys/42 girls, age 10.4±0.3 years) p...

Context/Objective: Given the increasing rates of both childhood obesity and type 2 diabetes (T2DM), we investigated whether maternal diabetes status during pregnancy is a determinant of risk factors associated with T2DM or cardiovascular disease in offspring during childhood. Design/Participants: Forty-two Pima Indians, aged 7–11 yr, were identified retrospectively from maternal oral glucose tolerance tests as offspring of a diabetic pregnancy (22 ODM, eight males, 14 females) or offspring born ...
