In this paper, we present a real-time algorithm for automatic recognition of not only physical activities, but also, in some cases, their intensities, using five triaxial wireless accelerometers and a wireless heart rate monitor. The algorithm has been evaluated using datasets consisting of 30 physical gymnasium activities collected from a total of 21(More)
BACKGROUND The increasing prevalence of overweight and obesity underscores the need for evidence-based, easily disseminable interventions for weight management that can be delivered on a population basis. The Transtheoretical Model (TTM) offers a promising theoretical framework for multiple behavior weight management interventions. METHODS Overweight or(More)
BACKGROUND Hypertension is more prevalent and clinically severe among African-Americans than whites. Several health behaviors influence blood pressure (BP) control, but effective, accessible, culturally sensitive interventions that target multiple behaviors are lacking. PURPOSE We evaluated a culturally adapted, automated telephone system to help(More)
BACKGROUND Little is known about disease-specific knowledge in patients with chronic kidney disease (CKD). We developed and examined the results of a survey to characterize kidney disease knowledge. DESIGN Survey about kidney disease knowledge, with questions developed by experts. SETTING & PARTICIPANTS 401 adult patients with CKD (stages 1-5) attending(More)
BACKGROUND Reliable, valid and theoretically consistent measures that assess a parent's self-efficacy for helping a child with obesity prevention behaviors are lacking. OBJECTIVES To develop measures of parental self-efficacy for four behaviors: 1) helping their child get at least 60 minutes of moderate intensity physical activity every day, 2) helping(More)
OBJECTIVE To assess the validity of 5 parental stage-of-change (SOC) measures: (1) providing 5 servings/d of fruits and vegetables (FV), (2) limiting television (TV) to 2 h/d, (3) helping children achieve 1 h/d physical activity (PA), (4) limiting sugary drinks (SD) to 1 serving/wk, and (5) limiting fruit juice (FJ) to 4-6 oz/d. DESIGN Cross-sectional(More)
OBJECTIVE To evaluate the acceptability and feasibility of a scalable obesity treatment program integrated with pediatric primary care (PC) and delivered using interactive voice technology (IVR) to families from underserved populations. DESIGN AND METHODS Fifty parent-child dyads (child 9-12 yrs, BMI > 95th percentile) were recruited from a pediatric PC(More)
OBJECTIVE Research indicates that healthful eating and physical activity (PA) practices implemented in child-care settings can have a positive effect on children's healthful behaviours in this setting, and this effect on healthful behaviours may possibly transfer to the home environment. While more research is needed to examine whether behaviours learned in(More)
Objective: To examine the types of life and dietary goals individuals report and how these goal domains interact as framed by goal systems theory. Methods: This work is a cross-sectional survey study. Measures included the incidence of common life and dietary goals and how these goals interact with and facilitate each other. Results: The results of a(More)
PURPOSE The purpose of this study was to examine the associations between different physical activity (PA) domains, PA recommendations, and leukocyte telomere length (LTL) using data from a nationally representative sample of U.S. adults in the National Health and Nutrition Examination Survey, 1999-2002. METHODS A total of 6933 U.S. adults (3402 men, 3531(More)
