The roles of informal social ties in affecting healthcare workers' risk of injury and assault were investigated in a longterm care facility for the elderly in the US. The original hypothesis was that nurses and healthcare assistants who integrated more with their coworkers would have lower risk. A crude measure of familiarity and social integration with coworkers was constructed from staff attendance records. This variable, which indicates working a floor and shift one has routinely worked on in the past, was associated with a moderate increase in risk of being injured after controlling for lifting demands and a fairly strong increased risk of being assaulted after controlling for resident combativeness. An interaction between social integration and job title was found. The primary associations were in the opposite direction of what was expected. The results suggest that social forces among healthcare workers shape the distribution of risk among workers in a manner more complex than some theories of social integration have suggested. New hypotheses are proposed to explore how social norms and expectations affect the way workers interact with each other and shape the distribution of risk among workgroup members.

Background: Healthy diets have been associated with better cognitive function. Socioeconomic factors including education, poverty, and job complexity may modify the relationship between diet and cognition.Methods: We used adjusted linear mixed models to examine the association between long-term adherence to the Mediterranean-Dietary Approaches to Stop Hypertension - Intervention for Neurodegenerative Delay (MIND) diet and cognitive function over 8 years of follow-up in Puerto Rican adults residing in the Boston, MA area (aged 45-75 years at baseline). We also examined whether the MIND diet-cognition association was confounded or modified by socioeconomic measures.Results: In both cross-sectional and longitudinal analyses the highest, versus lowest, MIND quintile was associated with better cognition function (β = 0.093; 95% CI: 0.035, 0.152; p trend = .0019), but not with cognitive trajectory over 8 years. Education <=8th grade (β = -0.339; 95% CI: 0.394, -0.286; p < .0001) and income-to-poverty ratio <120% (β = -0.049; 95% CI: -0.092, -0.007; p = .024) were significantly associated with lower cognitive function, while higher job complexity (β = 0.008; 95% CI: 0.006, 0.011; p < .0001) was associated with better cognition function. These variables acted as confounders, but not effect modifiers of the MIND-diet-cognitive function relationship.Conclusion: Adherence to the MIND diet was associated with better cognitive function at baseline and over 8 years of follow-up; however, MIND diet was not associated with 8-year cognitive trajectory. More studies are needed to better understand whether the MIND diet is protective against long-term cognitive decline. [ABSTRACT FROM AUTHOR]
