PAPH: Physical Activity and Population Health Research Lab PAPH Research Team is focused on the: development of efficacious/effective PA programs, for the primary and secondary prevention and treatment of cardio vascular disease and diabetes, and the promotion of general health.
Overview • Why Physical Activity? • Behaviour Change Theories • Examples in the Workplace • Recommendations • Scenario / discussion
RHA involvement in Schools, Workplaces, Health care, and community for 2002
Workplace Issues • Smoking Bans in workplaces; PA =/>more important (Population Health Perspective) • Time is one of the greatest barriers of PA – workplace is an ideal context for PA to, at & from work • Aging workforce • Workplace stress is increasing • 40% of workers want rec/ex. facilities/programs
Prevalence Approximately two-thirds of Canadian adults are risking their health and quality of life because of inactive lifestyles. (CFLRI, 2001)
Of Great Significance Physical Activity/CVD: Population Attributable Risk • ↑ Obesity • ↑ Diabetes Type II • = ↑Mortality/Morbidity & Economic Costs
individually oriented treatments interventions aimed at worksite organizations, health care settings and entire communities macro-level programs and healthy public policies Population Model of Prevention • Downstream – • Midstream – • Upstream – McKinlay’s (1995)
Importance of the Workplace • The majority of Canadian adults are in the workforce. • The majority of adults are (have been) employed in workplace settings.
Most Can. adults (15M) spend 1/2 their waking hours in the workplace • Workplaces offer unique opportunities for health promotion • Potential to be more successful than community settings - exposure to mass reach approaches
Employer Benefits of Workplace PA Programs • Corporate Image and recruitment • self-esteem, self-efficacy and self-determined employees • organizational support for good health practices • positive effect on work culture • Productivity • increased arousal, work satisfaction, leadership development, develops communication and interpersonal skills
Decreased absenteeism • Toronto Life Assurance- lower absenteeism was linked to to current participation rather membership versus non-membership • Decreased Turnover • studies indicate a reduction in turnover among active employees versus inactive • helped to retain female who were employed as clerks, service workers, semi-skilled operatives and general labourers
Lower medical costs • drug purchases • doctors’ visits • hospital days • disability days
Employee Benefits of PA • Improved health and well-being • Social benefits (Reducing barriers between co-workers) • Increase employee commitment
Health Benefits of Workplace PA Programs • Cancer • Type II Diabetes • Anxiety • Cardiac Risk • Health Hazard Appraisal Scores • Blood Pressure • Body Mass Index • Bone density
Workplace PA Meta-analysis: Moderators of intervention effects (r) Intervention Type: • Behaviour Modification (.34) • Exercise Prescription (.14) • Health Ed/Risk Appraisal (.06) Worksite: • University (.24) • Public (.14) • Corporate (.05) Setting • Onsite (.15) • Offsite (.13) Dishman et al. Am J of Prev Med15:344-361
Workplace PA Meta-analysis con’t: Activity Supervision • Supervised (.15) • Not supervised (.12) Incentive Reinforcement • Incentives (.18) • No Incentives (.10) PA Measure • Self-report (.14) • Cardiorespiratory fitness (.09)
How Successful are our programs? • Participation program rate is 20-30% with only half of these participating on a regular basis. • Of the best published intervention studies – at best “small effects” on program impact ie. fitness/behaviour ….We need programs… and better ones where ones exist.
Factors Associated with Participation Rates • Demographics: gender, socioeconomic status, occupation, visible minority groups (culture, language) • Organizational Capacity (will, infrastructure, leadership) • Working conditions • Physical environments
Practice (P) and Research (R) Limitations • Individual level focus (P & R) • Programs not theoretically grounded (P & R) • Poor measurement (i.e., validity / reliability) (P & R) • Poor definitions of the intervention (P) • Employer cost (i.e., time and money) (P) • Lack of randomized controlled trials (R)
Overview • Why Physical Activity? • Behaviour Change Theories • Examples in the Workplace • Recommendations • Scenario / discussion
Theories at the Individual Level: • Protection Motivation Theory • Theory of Planned Behavior • Transtheoretical Model • Social Cognitive Theory
Value Expectancy Theories 1.the desire to avoid illness or to get well (value) and, 2.The belief that a specific health action available to a person would prevent or remedy the illness - (expectancy).
Protection Motivation Theory Vulnerability Fear Severity THREAT APPRAISAL PROTECTION MOTIVATION Self Efficacy(perceived ability) Response Efficacy (perceived consequences) COPING APPRAISAL
Protection Motivation Theory Vulnerability Fear Severity THREAT APPRAISAL Intentions BEHAVIOR Self Efficacy(perceived ability) Response Efficacy (perceived consequences) COPING APPRAISAL
Theory of Planned Behavior Attitude Toward Behavior Subjective Norms Intention Behavior Perceived Behavioral Control
Transtheoretical Model • One of the most popular models in Health Promotion & Health Education in the past decade. • Prochaska & DiClemente (1983); originally based on smoking behaviour • Marcus – PA domain; worksite

Transtheoretical Model • Health practitioners seem to like it….Why? …staging concept; easy to use widgets

Workplace Physical Activity StudyPlotnikoff et al (under review, Am J Health Prom) • Large Randomized Controlled Trial in Alberta (n=900) • Funded by the Canadian Institutes for Health Research and Alberta Heritage Foundation for Medical Research
Methods - Results • Pre- and post-test exp/control group design • Interventions were delivered at baseline and 6 months • PA behaviour was assessed at baseline, 6 & 12 months
Women Stage 1200 Standard 1100 Control 1000 Group Physical Activity Means control 900 standard 800 stage 1 2 3 Time
Workplace Physical Activity and Healthy Eating - Electronic Messaging Study Plotnikoff, McCargar, Wilson & Loucaides (2005) American Journal of Health Promotion Funded by Health Canada
Purpose • To assess the efficacy of a 12-week electronic messaging intervention for the promotion of PA and nutrition behaviour in the workplace
Methods • 2598 employees - 5 large Canadian workplaces were randomized and completed baseline measures • Exp grp received 1 weekly PA and nutrition email message (with links) for 12 wks.
Men Exp. 960 940 Control 920 900 880 Estimated Marginal Means 860 GROUP 840 experimental group 820 800 control group 1 2 3 TIME
Discussion • Tailored print-based info on PA readiness worked well for women (Study 1) • General e-messaging worked for both genders (Study 2) • In follow-up interviews with 10% of Study 1, women > importance of tailoring messaging/information re: gender specificity • Consistent with much of women’s health information e.g., decisional aids
Discussion Con’t • Study recruitment: more women participants • Men have higher baseline activity scores than women (both studies) -- ceiling effects for men
Gender Differences - self-efficacy - intention - cons Men reported higher means Women reported higher means
