The fortification of commonly used foods with vitamin D and vitamin D supplementation seems to be an efficient way to increase the vitamin D intake and the vitamin D status in the adult population.
Objective: The present study is to describe, on the basis of recent Finnish population surveys, (i) the frequencies of school and worksite canteen use, (ii) the determinants of having a hot lunch during school or working hours and (iii) the associations of lunch eating patterns with food habits. Setting: The study summarises mainly basic reports and studies concerning catering services conducted in Finland based on nationally representative population surveys. Design and subjects: Cross-sectional study. The most important surveys cited in this paper are the School Health Promotion Study, the Work and the Working Conditions survey, the National FINDIET 2002 Study, and the Health Behavior and Health among Finnish Adult Population survey. Results: School lunch is eaten by on average 70-90 % of children aged 9-18 years. Of all employees, 30 % eat at a worksite canteen daily, whereas 30 % of men and 45 % of women eat packed lunches. Nationally representative cross-sectional population surveys show that the use of catering services is associated with more healthy food habits; schoolchildren eating school meals and employees eating lunch at a worksite canteen tend to make food choices closer to nutritional recommendations as compared to those not using catering services to the same degree. Conclusions: Some evidence exists that catering services in schools and worksites contribute to healthy eating habits in the population. In order to verify the positive role of catering services more scientific research with prospective and intervention design studies will be needed.
Objective: The aim of this study was to examine whether there are associations between working conditions and the use of staff canteen or packed meals among Finnish employees. Setting: Data were obtained from cross-sectional surveys on working conditions, conducted triennially (1997, 2000, 2003) since 1997. Subjects: In each survey, the subjects were 25-64-year-old employed Finnish employees: 3096 men and 3273 women. Results: Employees at large workplaces used canteens far more often than those at smaller workplaces. Working conditions played a different role in canteen use at small and large workplaces, as well as among the different sexes. At small workplaces, physically demanding jobs held by female employees and low job control encouraged employees to use the canteen. On the other hand, at large workplaces, low social support at work encouraged the use of canteens among men whereas high mental strain at work meant they used the canteen less. Among women, eating packed meals was not related to working conditions, but among men, low social support and high mental strain at work were associated with more frequent use of packed meals. Conclusions: The use of a staff canteen is largely determined by the size of the workplace and by employee education. The underlying factor could be the availability of canteens, a question which must be confirmed in further studies, since well-planned mass catering at workplaces has major effects on public health, well-being and the nutrition education of employees.
