Motivation Predicts Change in Nurses' Physical Activity Levels During a Web-Based Worksite Intervention: Results From a Randomized Trial.

Background: Low physical activity levels can negatively affect the health of nurses. Given the low physical activity levels reported by nurses, there is a clear need for brief and economical interventions designed to increase physical activity levels in this population. We developed a web-based intervention that used motivational strategies to increase nurses' physical activity levels.

Criterion-referenced mCAFT cut-points to identify metabolically healthy cardiorespiratory fitness among adults aged 18-69 years: an analysis of the Canadian Health Measures Survey.

This study aimed to develop and validate health-related criterion-referenced cut-points for the modified Canadian Aerobic Fitness Test (mCAFT), a field-based measure to predict cardiorespiratory fitness among adults (18-69 years). Criterion-referenced mCAFT cut-points were developed using nationally representative data from cycles 1 (2007-2009) and 2 (2009-2011) of the Canadian Health Measures Survey (CHMS). Receiver operating characteristic curves were used to identify age- and sex-specific cut-points for measured waist circumference, blood pressure, and high-density lipoprotein.

Establishing modified Canadian Aerobic Fitness Test (mCAFT) cut-points to detect clustered cardiometabolic risk among Canadian children and youth aged 9 to 17 years.

The objective of this study was to establish cut-points to identify potential clustered cardiometabolic risk among children (aged 9-13 years) and youth (aged 14-17 years) using the modified Canadian Aerobic Fitness Test (mCAFT). Nationally representative cross-sectional data were obtained from cycles 1 and 2 (2007-2011) of the Canadian Health Measures Survey. Cardiorespiratory fitness was measured using the mCAFT, which was used to estimate peak oxygen consumption.

Longitudinal qualitative study describing family physicians' experiences with attempting to integrate physical activity prescriptions in their practice: 'It's not easy to change habits'.

Objective: Physical activity (PA) prescriptions provided by family physicians can promote PA participation among patients, but few physicians regularly write PA prescriptions. The objective of this study was to describe family physicians' experiences of trying to implement written PA prescriptions into their practice.

Design: Longitudinal qualitative study where participants were interviewed four times during a 12-month period.
