- Objectives To compare levels of disability (in terms of physical function and self rated health) among middle aged and elderly people in Russia and Sweden, a country with high life expectancy. Design Cross sectional study. Setting General population of the Russian Federation and of two counties in southern Sweden. Participants Randomly selected men and women in Sweden (n = 9489) and Russia (n = 1599). Main outcome measures Official life table data, self rated health and physical functioning (subscale of the SF-36). Results The official life table data showed large differences in mortality-for example, 36% of Russian men aged 45-49 years would survive the next 25 years compared with 75% of Swedish men. The survey data showed, for both sexes, similar levels of self rated health and physical functioning in the two countries up to the age of about 45 years, but after that, the age related decline in both outcomes was much faster in Russia than in Sweden. By combining the national life tables with survey data on physical functioning we estimated that in the age group 45-49 years, 99% of Russian and 97% of Swedish men would be free of disability, of these, if these data were for a cohort, only 17% of Russians would be alive and free of disability 25 years later compared with 65% of Swedes. The difference in survival was similar in women. Conclusions Large differences exist in survival without disability between elderly Russians and Swedes. The short life span in Russia reflects high levels of ill health and disability and is associated with a rapid age related decline in physical functioning.

A comparative study of food intake between Lithuanian and Swedish middle-aged men : The LiVicordia study
- 2001

Journal article (pop. science, debate, etc.)abstract
- Background: In 1994, the mortality in coronary heart disease was four times higher among Lithuanian middle-aged men than among Swedish men. Over the period 1993-1995, the LiVicordia study investigated possible causes for this difference. We have earlier reported lower serum levels of cholesterol and higher susceptibility of low-density lipoprotein cholesterol for oxidation among Lithuanian men. Objective: In this part of the study, the aim was to compare mean estimates of food intake. Design: Cross-sectional study of random samples of 50-year-old men from each of the cities of Link÷ping, Sweden and Vilnius, Lithuania (n=150). The volunteers were interviewed about their food intake with the 24-hour recall method. Results: We found no differences in total energy intake, but Vilnius men had a higher energy intake from fat. Vilnius men consumed more fat from meat and less vegetable fat, while fat intake from dairy products was almost the same. Also, Vilnius men had a higher intake of vegetables, while Link÷ping men had a higher intake of fruit and berries. Conclusion: The observed differences in food consumption and dietary composition are partly consistent with the higher CHD mortality among Lithuanian men. However, data on biomarkers indicate that other dietary and lifestyle factors play a role.

The role of saliva cortisol measurements in health and disease : A matter of theory and methodology
- 2010
-
In: International Journal of Behavioral Medicine. - : Springer. - 1070-5503 .- 1532-7558. ; , s. S206-S206

Conference paper (peer-reviewed)abstract
- Over the last decade, the technique of using ambulatory salivary sampling has become increasingly popular in field research and clinical studies. The non-invasive method is easy to administer and analyze and allows implmentation in large scale study designs. However, this large interest in the use of salivary cortisol measurement is paralleled with frustrations on opposing results. This presentation is based on a critical evaluation of the existing literature on salivary cortisol, aiming to evaluate the utility of salivary cortisol as a biomarker in various settings and how we can understand cortisol reactivity using evidence of experiences from different study designs. The work is compiled by the Scandinavian Stress and Cortisol Network, a network financed by the Swedish Research Council, and one main question asked was: is it possible that different results of studies involving cortisol assessments are functions of differences in the theoretical assumptions made and methods used. In particular, the symposium will focus on how the many different ways of evaluating levels and dynamics of salivary cortisol (i. e. with regard to time points of assessment and different algorithms based on multiple time points) may have an impact on the interpretation of cortisol measurements in various contexts. Salivary cortisol has been studied in relation to the following topics: demographic variables, psychosocial work environment, psychosocial resources (e.g. mastery) and outcomes (e.g. burnout), sleep quality, biological markers (markers of cardivascular risk, inflammation and metabolism) and somatic outcome.
