The aim of this study was to investigate the relationship between the density of fast food restaurants and the prevalence of obesity by gender across affluent nations. Data on Subway's restaurants per 100,000 people and proportions of men and women aged 15 years or older with a body mass index (BMI) higher or equal than 30 Kg/m2 were obtained for 26 of 34 advanced economies. Countries with the highest density of Subway restaurants such as the US (7.52 per 100,000) and Canada (7.43 per 100,000) tend also to have a higher prevalence of obesity in both men (31.3% and 23.2% respectively) and women (33.2% and 22.9% respectively). On the other hand, countries with a relatively low density of Subway restaurants such as Japan (0.13 per 100,000) and Norway (0.19 per 100,000) had a lower prevalence of obesity in both men (2.9% and 6.4% respectively) and women (3.3% and 5.9% respectively). Unadjusted linear regression models showed a significant correlation between the density of Subway's outlets and the prevalence of adult obesity (β=.46; p=0.02 in men and β=.48; p=0.013 in women). When the data were weighted by population size, the association became substantially stronger in both men and women (β=.85; p=0.0001 and β=.84; p=0.0001, respectively). Covariate adjustment did not reduce the size of the associations. Our study raises serious concerns about that the diffusion of fast food outlets worldwide and calls for coordinated political actions to address what we term 'globesization', the ongoing globalization of the obesity epidemic.

Objectives: To investigate whether low perceived organisational injustice predicts heavy drinking among employees.Methods: Data from a prospective occupational cohort study, the 10-Town Study, on 15 290 Finnish public sector local government employees nested in 2432 work units, were used. Non-drinkers were excluded. Procedural, interactional and total organisational justice, heavy drinking (>= 210 g of absolute alcohol per week) and other psychosocial factors were determined by means of questionnaire in 2000-2001 (phase 1) and 2004 (phase 2). Multilevel logistic regression analyses taking into account the hierarchical structure of the data were conducted and adjustments were made for sex, age, socio-economic status, marital status, baseline heavy drinking, psychological distress and other psychosocial risk factors such as job strain and effort/reward imbalance.Results: After adjustments, participants who reported low procedural justice at phase 1 were approximately 1.2 times more likely to be heavy drinkers at phase 2 compared with their counterparts reporting high justice. Low perceived justice in interpersonal treatment and low perceived total organisational justice were associated with increased prevalence of heavy drinking only in the model adjusted for sociodemographics.Conclusions: This is the first longitudinal study to show that low procedural justice is weakly associated with an increased likelihood of heavy drinking.
