Cardiorespiratory Fitness Among Individuals With Psoriasis in the General Population

  • Published on Jul 2016

Background Psoriasis confers risk for cardiometabolic disorders. Cardiorespiratory fitness is inversely associated with risk of cardiometabolic disorders in other populations, but limited data have been published assessing cardiorespiratory fitness among individuals with psoriasis. This investigation aimed to: 1) assess cardiorespiratory fitness among individuals with psoriasis in the general population; and 2) compare ...


National youth sedentary behavior and physical activity daily patterns using latent class analysis applied to accelerometry

  • Published on May 3, 2016

Background: Applying latent class analysis (LCA) to accelerometry can help elucidated underlying patterns. This study described the patterns of accelerometer-determined sedentary behavior and physical activity among youth by applying LCA to a nationally representative United States (US) sample. Methods: Using 2003–2006 National Health and Nutrition Examination Survey data, 3998 youths 6–17 ...


The descriptive epidemiology of accelerometer-measured physical activity in older adults

  • Published on Jan. 7, 2016

Background: Objectively measured physical activity between older individuals and between populations has been poorly described. We aimed to describe and compare the variation in accelerometry data in older UK (EPIC-Norfolk) and American (NHANES) adults. Methods: Physical activity was measured by uniaxial accelerometry in 4,052 UK (49–91 years) and 3459 US older adults (49...


Physical activity and sedentary behavior measured objectively and subjectively in overweight and obese adults with schizophrenia or schizoaffective disorders.

  • Published on Oct. 2015

Objective: Describe objective and subjective physical activity levels and time spent being sedentary in adults with schizophrenia or schizoaffective disorders (SZO/SA). Method: Baseline physical activity and sedentary behaviors were assessed among 46 overweight and obese community-dwelling adults (aged 18-70 years; BMI > 27 kg/m(2)) diagnosed with SZO/SA by DSM-IV-TR, with ...


Accelerometer-Derived Pattern of Sedentary and Physical Activity Time in Persons with Mobility Disability: National Health and Nutrition Examination Survey 2003 to 2006

  • Published on July 14, 2015

Objectives: To describe objectively determined sedentary and activity outcomes (volume and pattern) and their associations with cardiometabolic risk biomarkers in individuals with and without mobility disability. Design: Cross-sectional Setting: Population based Participants: Community-dwelling older adults (≥60) living in the United States who were participants in the 2003 to 2004 or 2005 to 2006 National ...


Classification of occupational activity categories using accelerometry: NHANES 2003–2004

  • Published on June 30, 2015

Background: An individual’s occupational activity (OA) may contribute significantly to daily physical activity (PA) and sedentary behavior (SB). However, there is little consensus about which occupational categories involve high OA or low OA, and the majority of categories are unclassifiable with current methods. The purpose of this study was ...


Accelerometer determined sedentary behavior and dietary quality among US adults

  • Published on July 2, 2015

Objective: Scant evidence exists pertaining to objectively measured sedentary time and dietary quality among adults. Therefore, we examined the relationships between sedentary time, physical activity, and dietary quality. Methods: Cross-sectional analyses of a 4,910 US adults from two cycles (2003–2006) of the National Health and Nutrition Examination Survey. The primary independent ...


Combined Effects of Time Spent in Physical Activity, Sedentary Behaviors and Sleep on Obesity and Cardio-Metabolic Health Markers: A Novel Compositional Data Analysis Approach

  • Published on Oct. 13, 2015

Abstract: The associations between time spent in sleep, sedentary behaviors (SB) and physical activity with health are usually studied without taking into account that time is finite during the day, so time spent in each of these behaviors are codependent. Therefore, little is known about the combined effect of time ...


Secular differences in the association between caloric intake, macronutrient intake, and physical activity with obesity

  • Published on Sept. 14, 2015

Background: To determine whether the relationship between caloric intake, macronutrient intake, and physical activity with obesity has changed over time. Methods: Dietary data from 36,377 U.S. adults from the National Health and Nutrition Survey (NHANES) between 1971 and 2008 was used. Physical activity frequency data was only available in 14,419 adults between 1988 and 2006. ...


Diet quality and physical activity in relation to childhood obesity

  • Published on Aug. 15, 2015

Objective: Healthy lifestyles such as being physically active and eating a healthy diet help reduce the childhood obesity risk. However, population-level studies on the relationship between lifestyles and childhood obesity typically focus on either physical activity or diet but seldom both. This study examined physical activity and diet quality in ...
