Evaluation of the ability of three physical activity monitors to predict weight change and estimate energy expenditure.

Activity monitors such as the Actical accelerometer, the Sensewear armband, and the Intelligent Device for Energy Expenditure and Activity (IDEEA) are commonly validated against gold standards (e.g., doubly labeled water, or DLW) to determine whether they accurately measure total daily energy expenditure (TEE) or activity energy expenditure (AEE).

Relatively Low β-Cell Responsiveness Contributes to the Association of BMI with Circulating Glucose Concentrations Measured under Free-Living Conditions among Pregnant African American Women.

Background: Body mass index (BMI, in kg/m(2)) is positively associated with plasma glucose in late pregnancy and with risk of adverse obstetric outcomes. Much of the existing research uses single-clinic measures of plasma glucose, which may not accurately reflect circulating glucose under free-living conditions. Furthermore, little is known about circulating glucose concentrations of African American women, who tend to have poorer diet quality and a greater risk of obstetric complications.

Prospective associations of eating behaviors with weight gain in infants.

Objective: To examine whether maternal reports of infant eating behaviors are stable over time and whether eating behaviors are prospectively associated with weight gain.

Methods: In an ongoing study of infant growth, weight and length were measured at 2 weeks, 3 months, and 5 months of age. Food responsiveness (FR), satiety responsiveness (SR), enjoyment of feeding (EF), and slow eating (SE) were assessed with the Baby Eating Behavior Questionnaire.

Short-term overeating results in incomplete energy intake compensation regardless of energy density or macronutrient composition.

Objective: To evaluate the effects of overeating (140% of energy requirements) a high-fat low-energy density diet (HF/LED, 1.05 kcal/g), high-fat high-energy density diet (HF/HED, 1.60 kcal/g), and high-carbohydrate (HC) LED (1.

The impact of parental trauma exposure on community violence exposed adolescents.

Previous research has documented an association between adolescent community violence (CV) exposure and poor psychological functioning. The purpose of this study was to delineate the relations of adolescent CV, parent trauma exposure (PTE), and adolescent internalizing and externalizing symptomatology while controlling for adolescent-reported home violence and parental self-reported posttraumatic stress disorder (PTSD). Participants consisted of 101 pairs of junior high school and high school students and their parents or caretakers.
