GARCIA-DIAZ, Vanesa; FERNANDEZ-FEITO, Ana; ARIAS, Lucía  and  LANA, Alberto. Tobacco and alcohol consumption according to workday in Spain. Gac Sanit [online]. 2015, vol.29, n.5, pp.364-369. ISSN 0213-9111.

Objective: To examine the association between smoking and alcohol consumption and the type of working day in the Spanish population Methods: Cross-sectional study among employees residing in Spain aged >18 years (N = 8,736). We took data from the National Health Survey (2011-2012). Information was collected on the type of working day (morning, afternoon, evening, part-time, reduced hours, and shift-work) and smoking and drinking habits. Demographic characteristics and health- and work-related factors were also taken into account. Adjusted odds ratios (aOR) and 95% confidence intervals (95%CI) were calculated through log-binomial regressions. Results: Among respondents, 32.1% smoked regularly, especially those working the night shift (43.5%). Moderate alcohol consumption was found in 54.8% of workers and excessive consumption in 1.5%. Most of the moderate and heavy drinkers worked part-time, with 57.6% and 1.8% respectively. The aOR of being a smoker was higher among night workers (OR = 1.58; 95% CI: 1.01-2.46). None of the work shifts were significantly associated with alcohol consumption. Conclusions: Night shift work was associated with regular smoking. This collective of workers should be monitored closely by occupational health services and regularly undergo programs to control tobacco consumption and smoking-related diseases. Additional research to elucidate the reasons for this association could help to achieve preventive and therapeutic success.
