Given the lagged inter-relationship of PI, AL and PR, the provision and timing of interventions targeting all constructs are critical to maximizing outcome. Current care pathways focusing on short-term follow-up with limited attention to social and community participation should be re-evaluated.
The present study examined the relationship between work-family spillover, job characteristics, and sleep quality in a sample of health care workers (N = 168) recruited from 3 Canadian hospitals. A multiple regression analysis revealed that positive family-to-work spillover is associated with better sleep quality, after controlling for age, physical health, depressive symptomatology, work situation, and number of children. These findings are discussed within a theoretical framework drawing on the concepts of effort and recovery.
A range of determinants at multiple socio-ecological levels operate in small farm households' use and handling of hazardous pesticides, suggesting the need for integrated health and agriculture promotion approaches. The aim is to assess changes in health promotion outcomes relevant to highly hazardous pesticide use associated with a multi-component community program. A longitudinal evaluation design using mixed methods was employed in 18 agricultural communities in Ecuador. Over a 7-month period, health education and agricultural interventions focused upon: health risks associated with hazardous pesticides, more adequate use and handling of pesticides, and better crop management techniques. Data collection included field forms, focus groups, structured observations and repeat surveys. In the qualitative analysis, communities were compared by extent of leadership and involvement with the interventions. For the quantitative analysis, hypothesized paths were constructed including factors relevant to pesticide-related practices and use. Testing involved gender-role stratified (household and crop manager) multivariable regression models. Information on pesticide health impacts and the pesticide use and handling, shared in focus groups, showed substantial improvement, as a result of health promotion activities though people were still observed to engage in risky practices in the field. In path models, community leadership and intervention intensity lead to changes in the household managers' pesticide-related knowledge and practices and to reduction in farm use of hazardous pesticides (both significant, p < 0.05). Integrated, community programs can promote pesticide-related risk reduction among small farm households. Changing practices in the use and management of pesticides among crop managers appears limited by deeper structural and cultural factors.
Objectives-To describe the prevalence of musculoskeletal problems in the Canadian working population and to determine cross sectional associations between such problems and work factors, particularly job strain and physical demand variables. Methods-The Canadian 1994 national population health survey (NPHS) sampled 4230 working men and 4043 working women (ages 18-64) who answered an abbreviated version of the job content questionnaire. Workers were classified into four strain categories: high, passive, active, and low. Outcomes were restricted activity due to musculoskeletal disorders and the diagnosis of a back problem (both yes or no). Survey weights were incorporated to allow for diVerent probabilities of selection. Logistic regression analyses were carried out separately for women and men, controlling for sociodemographic factors. Results-Prevalence of chronic back problems diagnosed by a health practitioner was 14.5% among men and 12.5% among women. Men had a 6.6% prevalence of restricted activity due to musculoskeletal disorders, whereas the corresponding figure for women was 5.3%. Women, but not men, in high strain jobs were more likely to report both back problems (odds ratio (OR) 1.60, 95% confidence interval (95% CI) 1.14 to 2.28) and restricted activity (OR 1.98, 95% CI 1.16 to 3.48) compared with those in low strain jobs. High physical exertion was an independent predictor of back problems in both sexes. For both men and women, low social support at work and high job insecurity were independent predictors of restricted activity due to musculoskeletal disorders. Conversely, chronic back problems contributed to explanation of high job strain among women (OR 1.76, 95% CI 1.30 to 2.39) and high physical exertion among men (OR 1.39, 95% CI 1.09 to 1.77), whereas restricted activity due to musculoskeletal disorders contributed to explanation of high job insecurity in both sexes. Conclusions-Associations of interest between work stressors and musculoskeletal problems in this cross sectional study provide evidence for physical and psychosocial factors both aVecting disability and being aVected by disability in a working population.

A PE approach can improve risk factors related to WMSD, and meaningful worker participation in the process is an important aspect for the success of such interventions.
