: The purpose of this study was to evaluate the implementation and effectiveness of an ecological, multi-component adolescent obesity prevention intervention called School Wellness Integration Targeting Child Health-Middle School (SWITCH-MS). : Following the effectiveness-implementation hybrid type 3 quasi-experimental design, seven middle schools (377 students) in Iowa, United States, were stratified into "experienced" ( = 3; 110 students) or "inexperienced" ( = 4; 267 students) groups to receive the 12-week SWITCH-MS intervention. To evaluate implementation, school informants ( = 10) responded to a survey and students completed behavioral tracking in the classroom on a website.

The Importance of Self-Monitoring for Behavior Change in Youth: Findings from the SWITCH School Wellness Feasibility Study.

School Wellness Integration Targeting Child Health (SWITCH) is a school wellness implementation initiative focused on building capacity for schools to plan and coordinate wellness programming. Grounded in Social Cognitive Theory (SCT), the purpose of this study was to evaluate the utility of the web-based, self-regulation system on physical activity (PA) behavior outcomes. At pre-test and post-test, students in SWITCH schools ( = 8) completed the online Youth Activity Profile (YAP) to assess PA and sedentary behavior (SB).

Comparison of the Cardiovascular Benefits of Resistance, Aerobic, and Combined Exercise (CardioRACE): Rationale, design, and methods.

Background: The benefits of aerobic exercise (AE) for cardiovascular disease (CVD) have been well documented. Resistance exercise (RE) has been traditionally examined for its effects on bone density, physical function, or metabolic health, yet few data exist regarding the benefits of RE, independent of and combined with AE, for CVD prevention. This randomized controlled trial, "Comparison of the Cardiovascular Benefits of Resistance, Aerobic, and Combined Exercise (CardioRACE)," is designed to determine the relative benefits of RE, AE, or combined RE plus AE training on CVD risk factors.

Implementing Follow-Along Physical Activity Videos with People Living With Chronic Conditions: A Feasibility Study.

Background: Compelling evidence supports multiple benefits of physical activity (PA) even in small bursts. Less than 50% of Americans achieve recommended PA levels, lower still for individuals living with chronic illness or disease.

Purpose: The purpose of this study was to develop and evaluate the feasibility and preliminary effects of 3-min follow-along video scenarios to promote brief episodes of low-moderate levels of PA among individuals with chronic diseases.

Family Legacy of Diabetes-Related Behaviors: An Exploration of the Experiences of African American Parents and Adult Children.

African Americans are at higher risk of developing type 2 diabetes mellitus (T2DM), and this risk may be influenced by familial experiences and cultural norms throughout the life course. This led us to conduct this study of 20 African American families with strong histories of T2DM to explore familial complexities that prevent or help manage diabetic symptoms. Experiences were analyzed inductively through individual family profiles created using content-analytic summaries.

Feasibility study of the SWITCH implementation process for enhancing school wellness.

Background: There is a need to identify strategies that enhance the implementation of evidence-based school wellness intervention programs in real-world settings. The present study evaluates the feasibility of empowering school wellness leaders to deliver an evidence-based, childhood obesity-prevention program called Switch ™. We specifically evaluated the feasibility of a new implementation framework, based on the robust Healthy Youth Places framework, to increase capacity of school leaders to lead school wellness programming.

Worksite Physical Activity Intervention for Ambulatory Clinic Nursing Staff.

Health behaviors, including physical activity (PA), of registered nurses (RNs) and medical assistants (MAs) are suboptimal but may improve with worksite programs. Using a repeated-measures crossover design, the authors explored if integrating a 6-month worksite non-exercise activity thermogenesis (NEAT) intervention, with and without personalized health coaching via text messaging into workflow could positively affect sedentary time, PA, and body composition of nursing staff without jeopardizing work productivity. Two ambulatory clinics were randomly assigned to an environmental NEAT intervention plus a mobile text message coaching for either the first 3 months (early texting group, n = 27) or the last 3 months (delayed texting group, n = 13), with baseline 3-month and 6-month measurements.

Web-Based Behavioral Intervention Increases Maternal Exercise but Does Not Prevent Excessive Gestational Weight Gain in Previously Sedentary Women.

Background: Innovative methods are warranted to optimize prenatal outcomes. This study's objective was to determine if a web-based behavioral intervention (BI) can prevent excessive gestational weight gain (GWG) by increasing physical activity (PA).

Methods: Participants were randomized to usual care (UC; n = 21) or BI (n = 24) between 10 to 14 weeks gestation.

Nurse-Led School-Based Child Obesity Prevention.

School-based childhood obesity prevention programs have grown in response to reductions in child physical activity (PA), increased sedentariness, poor diet, and soaring child obesity rates. Multiple systematic reviews indicate school-based obesity prevention/treatment interventions are effective, yet few studies have examined the school nurse role in obesity interventions. Building on a previous study, this study examines a refined health messaging (Let's Go 5-2-1-0) program delivered to fourth and fifth graders (n = 72) by a school nurse with reinforcement on-site health coaching by senior nursing students.

Impact of a walking intervention during pregnancy on post-partum weight retention and infant anthropometric outcomes.

Few studies have investigated the impact of lifestyle interventions during pregnancy on post-partum weight retention and infant growth. Thirty seven previously non-exercising, overweight or obese pregnant women were randomly assigned to a walking intervention or non-intervention control. For the follow-up study, weight of the mother and weight, length and body composition of the infant were collected at 1 month post-partum (n=37) and 6 months post-partum (n=33).

Methods: Thirty healthy pregnant women (22-24 wk of gestation) completed a series of activities of daily living (typing, laundry, sweeping, and treadmill walking: 2.

The energy expenditure of an activity-promoting video game compared to sedentary video games and TV watching.

Background: In the present study we investigated the effect of television watching and the use of activity-promoting video games on energy expenditure in obese and lean children.

Methods: Energy expenditure and physical activity were measured while participants were watching television, playing a video game on a traditional sedentary video game console, and while playing the same video game on an activity-promoting video game console.

Results: Energy expenditure was significantly greater than television watching and playing video games on a sedentary video game console when children played the video game on the activity-promoting console.

Effects of a worksite physical activity intervention for hospital nurses who are working mothers.

Hospital nurses who are working mothers are challenged to maintain their personal health and model healthy behaviors for their children. This study aimed to develop and test an innovative 10-week worksite physical activity intervention integrated into the work flow of hospital-based nurses who were mothers. Three volunteer adult medical-surgical nursing units participated as intervention units.

A school based community partnership for promoting healthy habits for life.

Childhood obesity rates continue to increase and there is a need for innovative obesity prevention programs. Our objectives were to (1) create a community partnership, and (2) test an obesity prevention intervention that involved curriculum delivered in the classroom with 1:1 coaching delivered by nursing students on health parameters among 4th and 5th grade school children. Our primary hypothesis was that the intervention would result in significant increases in physical activity levels.

Energy intake during activity enhanced video game play.

The purpose of this study was to examine whether the addition of a motor component to video gaming alters energy consumption. To address this problem we used an experimental manipulation design with 9-13 year olds incorporating 'seated video game' and 'activity enhanced video game' conditions, whilst allowing snacks ad libitum. No difference in snacking between the two video gaming conditions was apparent.

Activity-promoting video games and increased energy expenditure.

Objectives: To test the hypothesis that both children and adults would expend more calories and move more while playing activity-promoting video games compared with sedentary video games.

Study Design: In this single-group study, 22 healthy children (12 +/- 2 years; 11 male, 11 female) and 20 adults (34 +/- 11 years; 10 male, 10 female) were recruited. Energy expenditure and physical activity were measured while participants were resting, standing, watching television seated, sitting and playing a traditional sedentary video game, and while playing an activity-promoting video game (Nintendo Wii Boxing).

Pedometer accuracy for children: can we recommend them for our obese population?

Objective: In this study, we investigated the accuracy of measuring walking steps with commercially available pedometers and an accelerometer-based step-counter in normal and overweight children. Our primary hypothesis was that commercially available pedometers are not an accurate measure of walking steps in normal and overweight children while walking. Our secondary hypothesis was that the accelerometer-based step-counter provides an accurate measure of walking steps in normal and overweight children.

The feasibility of ambulatory screen time in children.

Purpose: A walking media station was developed, which enables normally seated screen activities to be conducted whilst walking. This study tests feasibility of the walking media station and provides preliminary evidence of the acceptability of the device in the home environment.

Methods: Twenty-nine healthy children (mean age 9.

Changing the school environment to increase physical activity in children.

We examined the hypothesis that elementary school-age children will be more physically active while attending school in a novel, activity-permissive school environment compared to their traditional school environment. Twenty-four children were monitored with a single-triaxial accelerometer worn on the thigh. The students attended school in three different environments: traditional school with chairs and desks, an activity-permissive environment, and finally their traditional school with desks which encouraged standing.
