Associations Of Smoking Status And Serious Psychological Distress With Chronic Obstructive Pulmonary Disease, Ke-Sheng Wang, Liang Wang, Shimin Zheng, Long-Yang Wu

Shimin Zheng

Background: Chronic obstructive pulmonary disease (COPD) has been a major public health problem due to its high prevalence, morbidity, and mortality. Smoking is a major risk factor for COPD, while serious psychological distress (SPD) is prevalent among COPD patients. However, no study focusing on the effect of SPD on COPD has been so far conducted, while few studies have focused on the associations of SPD and behavioral factors with COPD by smoking status. Objectives: This study aimed to examine the associations of SPD and behavioral factors (such as smoking and physical activity) with COPD. Materials and Methods: Weighted logistic regression …

Healthy Eating And Physical Activity Challenges And Opportunities In After-School Programs: Providers’ Perspectives, Heather Thomas, L. Fellner, Patricia Tucker, Jennifer Irwin

Trish Tucker

The purpose of this study was to understand after-school program providers’ perspectives of (a) current physical activity and nutrition curriculum, practices, and challenges, and (b) necessary modifications, program suggestions or resource needs to improve the healthy eating and active living practices within their after-school program for children aged 6 to 12 years. This qualitative study targeted a sample of nine after-school program providers in London, Ontario. Data was collected via in-depth interviews and a demographic survey between January and April 2009. Strategies to enhance data trustworthiness were incorporated throughout. After-school program providers identified insufficient healthy eating curriculum and requested interactive, …

The Impact Of Co-Active Coaching On Physically Inactive 12 To 14 Year Olds In Ontario, Paul Gorczynski, Don Morrow, Jennifer Irwin

Donald Morrow

This study assessed the impact of life coaching on physical activity participation, self-efficacy, social support, and perceived behavioural control among physically inactive youth between the ages of 12 and 14 years in London, Ontario. The multiple-baseline across participants single case-experimental design study consisted of five 12 to 14 year olds. Six coaching sessions were conducted over two months by a certified professional Co-active coach. Physical activity increased for one participant while the other participants’ physical activity remained unchanged. No significant changes occurred in self-efficacy, social support, and perceived behavioural control with specific regard to becoming more physically active. Results indicted …

Calibrating A Novel Multi-Sensor Physical Activity Measurement System, D. John, S. Liu, J. Saski, C. Howe, J. Staudenmayer, R. Gao, Patty Freedson

Patty S. Freedson

Advancing the field of physical activity (PA) monitoring requires the development of innovative multi-sensor measurement systems that are feasible in the free-living environment. The use of novel analytical techniques to combine and process these multiple sensor signals is equally important. This paper, describes a novel multi-sensor ‘Integrated PA Measurement System’ (IMS), the lab-based methodology used to calibrate the IMS, techniques used to predict multiple variables from the sensor signals, and proposes design changes to improve the feasibility of deploying the IMS in the free-living environment. The IMS consists of hip and wrist acceleration sensors, two piezoelectric respiration sensors on the …

Efficacy Of A Family Practice-Based Lifestyle Intervention Program To Increase Physical Activity And Reduce Clinical And Physiological Markers Of Vascular Health In Patients With High Normal Blood Pressure And/Or High Normal Blood Glucose (Snac): Study Protocol For A Randomized Controlled Trial, Robert Petrella, Kuni Aizawa, Kevin Shoemaker, Tom Overend, Leonard Piché, Mauricio Marin, Sheree Shapiro, Sophie Atkin

Leonard Piché

BACKGROUND: Previous interventions to increase physical activity and reduce cardiovascular risk factors have been targeted at individuals with established disease; less attention has been given to intervention among individuals with high risk for disease nor has there been determination of the influence of setting in which the intervention is provided. In particular, family practice represents an ideal setting for the provision and long-term maintenance of lifestyle interventions for patients at risk (ie high-normal blood pressure or impaired glucose tolerance).

METHODS/DESIGN: The Staged Nutrition and Activity Counseling (SNAC) study is a randomized clustered design clinical trial that will investigate the effectiveness …
