Effects on cigarette consumption of a work-family supportive organisational intervention: 6-month results from the work, family and health network study

Background Observational studies have linked work- family issues with cigarette consumption. This study examined the 6-month effects on cigarette consumption of a work-family supportive organisational intervention among nursing home workers. Methods Group randomised controlled trial where 30 nursing homes across New England states were randomly assigned to either usual practice or to a 4- month intervention aimed at reducing work-family conflict via increased schedule control and family supportive supervisory behaviours (FSSB). Cigarette consumption was based on self-reported number of cigarettes per week, measured at the individual level. Results A total of 1524 direct-care workers were enrolled in the trial. Cigarette consumption was prevalent in 30% of the sample, consuming an average of 77 cigarettes/week. Smokers at intervention sites reduced cigarette consumption by 7.12 cigarettes, while no reduction was observed among smokers at usual practice sites (b=-7.12, 95% CI -13.83 to -0.40, p
