- BACKGROUND: Employees working night shifts are at a greater risk of being overweight or obese. Few studies on obesity and weight gain analyze the years of exposure to night work. The aim of this study was to determine the relationship between the years of exposure to night work and body mass index (BMI) among registered nurses.METHODS: A cross-sectional analysis was performed in 18 largest public hospitals in Rio de Janeiro, Brazil. A total of 2,372 registered nurses (2,100 women) completed a comprehensive questionnaire concerning sociodemographic, professional, lifestyle, and health behavioral data. Current and past exposures to night shifts as well as BMI values were measured as continuous variables. A gamma regression model was used with an identity link function to establish the association.RESULTS: The association between years of exposure to night work and BMI was statistically significant for both women and men after adjusting for all covariates [β = 0.036; CI95% = 0.009-0.063) and β = 0.071 (CI95% = 0.012-0.129), respectively]. The effect of night work was greater among men than women. For example, for those women who have worked at night for 20 years the estimated average BMI was 25.6 kg/m2 [range, 25.0-26.2]. In relation to men, after 20 years of exposure to night work the estimated average BMI was 26.9 kg/m2 [range, 25.6-28.1].CONCLUSIONS: These findings suggest that night shift exposure is related to BMI increases. Obesity prevention strategies should incorporate improvements in work environments, such as the provision of proper meals to night workers, in addition to educational programs on the health effects of night work.

- OBJECTIVE To evaluate the cross-cultural validity of the Demand-Control Questionnaire, comparing the original Swedish questionnaire with the Brazilian version. METHODS We compared data from 362 Swedish and 399 Brazilian health workers. Confirmatory and exploratory factor analyses were performed to test structural validity, using the robust weighted least squares mean and variance-adjusted (WLSMV) estimator. Construct validity, using hypotheses testing, was evaluated through the inspection of the mean score distribution of the scale dimensions according to sociodemographic and social support at work variables. RESULTS The confirmatory and exploratory factor analyses supported the instrument in three dimensions (for Swedish and Brazilians): psychological demands, skill discretion and decision authority. The best-fit model was achieved by including an error correlation between work fast and work intensely (psychological demands) and removing the item repetitive work (skill discretion). Hypotheses testing showed that workers with university degree had higher scores on skill discretion and decision authority and those with high levels of Social Support at Work had lower scores on psychological demands and higher scores on decision authority. CONCLUSIONS The results supported the equivalent dimensional structures across the two culturally different work contexts. Skill discretion and decision authority formed two distinct dimensions and the item repetitive work should be removed.

- AIMS: This study explored the association between income and stroke mortality in the total working population in Sweden and examined whether the associations differ by gender or for stroke subtypes intracerebral haemorrhage (ICH) or brain infarction (BI).METHODS: This was a register-based study among nearly 3 million working women and men (30-64 years in 1990) with a 12-year follow up (1991-2002) for mortality from stroke (4886 deaths). Income was measured as annual registered income from work in 1990. Gender-specific Cox regressions were applied with adjustments for sociodemographic covariates.RESULTS: The age-adjusted hazard ratio (95% confidence interval) of lowest versus highest income quartile was 1.80 (1.48-2.19) for any stroke, 1.68 (1.29-2.17) for ICH and 2.23 (1.53-3.22) for BI in women, and the corresponding figures for men were 2.12 (1.92-2.34), 2.02 (1.77-2.31), and 2.09 (1.77-2.46). Adjustment for covariates attenuated these associations to 1.69 (1.33-2.15) for any stroke and 1.56 (1.14-2.14) for ICH in women and to 1.98 (1.74-2.24) for any stroke and 1.77 (1.44-2.19) for BI in men. In contrast, adjustment for covariates amplified the estimates to 2.36 (1.52-3.66) for BI in women and to 2.05 (1.73-2.44) for ICH in men.CONCLUSIONS: Risk of stroke mortality was highest in the lowest income group, with a gradient for the intermediate groups, in both women and men. The risk of mortality from BI was highest in women with the lowest income and the risk of ICH was highest in men with the lowest income.
