Racial/Ethnic Differences in Physical Activity in a Low-Income Sample in Texas.

Introduction: National data reveal that the age-adjusted prevalence of leisure-time physical inactivity is higher among Blacks and Hispanics compared with Whites. However, these estimates do not consider nonleisure physical activity (PA). Also, race/ethnicity in these findings may by confounded by socioeconomic status disparities in PA.

Five U.S. Dietary Patterns and Their Relationship to Land Use, Water Use, and Greenhouse Gas Emissions: Implications for Future Food Security.

The U.S. agri-food system is a driver of climate change and other impacts.

Associations between variety of fruits and vegetables consumed, diet quality and socio-demographic factors among 8th and 11th grade adolescents in Texas.

Objective: To examine demographic and dietary correlates of consumption of a variety of fruits and vegetables (FV) among Texas adolescents. Different types of FV are needed for adequate dietary intake of vitamins and phytochemicals for proper development and functioning throughout the lifespan.

Design: Cross-sectional analysis from the Texas Surveillance of Physical Activity and Nutrition (Texas SPAN) data comparing consumption of a variety of fruit and vegetables by gender, race/ethnicity and region (Texas-Mexico border/non-border).

A Scoping Review of the Operationalization of Fruit and Vegetable Variety.

Adequate consumption of fruits and vegetables is critical for healthy growth and development. Less is known about fruit and vegetable variety, with variation in operationalization of variety. This review aims to identify currently available evidence operationalizing fruit and vegetable (FV) variety through a scoping review to summarize, compare, and critically evaluate the operationalization of variety.

Bidirectional 10-year associations of accelerometer-measured sedentary behavior and activity categories with weight among middle-aged adults.

Background: Although higher sedentary behavior (SB) with low light intensity (LPA) and moderate-to-vigorous intensity physical activity (MVPA) are thought to increase risk for obesity, other data suggest excess weight may precede these behaviors in the causal pathway. We aimed to investigate 10-year bidirectional associations between SB and activity with weight.

Methods: Analysis included 886 CARDIA participants (aged 38-50 years, 62% female, 38% black) with weight and accelerometry ( ≥ 4 days with ≥ 10 h/day) collected in 2005-6 (ActiGraph 7164) and 2015-6 (ActiGraph wGT3X-BT).

Health by Design: Interweaving Health Promotion into Environments and Settings.

The important influence of the environmental context on health and health behavior-which includes place, settings, and the multiple environments within place and settings-has directed health promotion planners from a focus solely on changing individuals, toward a focus on harnessing and changing context for individual and community health promotion. Health promotion planning frameworks such as Intervention Mapping provide helpful guidance in addressing various facets of the environmental context in health intervention design, including the environmental factors that influence a given health condition or behavior, environmental agents that can influence a population's health, and environmental change methods. In further exploring how to harness the environmental context for health promotion, we examine in this paper the concept of , defined as weaving or blending together health promotion strategies, practices, programs, and policies to fit within, complement, and build from existing settings and environments.

Sedentary Time, Physical Activity, and Adiposity: Cross-sectional and Longitudinal Associations in CARDIA.

Introduction: Higher sedentary time (ST) and lower moderate- to vigorous-intensity physical activity (MVPA) have each been associated with greater adiposity, but most studies are cross-sectional and measure ST and MVPA by self-report. This study evaluated associations between objective ST and MVPA with current and 5-year changes in BMI and waist circumference.

Methods: The Coronary Artery and Risk Development in Young Adults longitudinal cohort study recruited black or white young adults from four U.

Relationship Between Midlife Cardiovascular Health and Late-Life Physical Performance: The ARIC Study.

Objectives: To examine the association between midlife cardiovascular health and physical performance 25 years later.

Design: Cohort study (Atherosclerosis Risk in Communities Study); multinomial logistic and logistic regression adjusted for demographic characteristics and clinical measures.

Setting: Four U.

Association Between Sitting Time and Cardiometabolic Risk Factors After Adjustment for Cardiorespiratory Fitness, Cooper Center Longitudinal Study, 2010-2013.

Introduction: Objective estimates, based on waist-worn accelerometers, indicate that adults spend over half their day (55%) in sedentary behaviors. Our study examined the association between sitting time and cardiometabolic risk factors after adjustment for cardiorespiratory fitness (CRF).

Methods: A cross-sectional analysis was conducted with 4,486 men and 1,845 women who reported daily estimated sitting time, had measures for adiposity, blood lipids, glucose, and blood pressure, and underwent maximal stress testing.
