National diabetes prevention program (DEHKO): awareness and self-reported lifestyle changes in Finnish middle-aged population.

OBJECTIVES: The national development programme for the prevention and care of diabetes was carried out in Finland during 2000-2010. One of the programme goals was to raise awareness of diabetes and its risk factors in the whole population through various activities, e.g. media campaigns and health fares. In addition, a targeted implementation project on the prevention of type 2 diabetes, FIN-D2D, was carried out in selected districts during 2003-2008. The aim of this analysis was to examine the changes in overall awareness of the programme and its association with self-reported lifestyle changes within the adult population during the FIN-D2D project period in the FIN-D2D area compared with the area not participating in the FIN-D2D (the control area). STUDY DESIGN: Health behaviour and health among the Finnish Adult Population -postal survey. METHODS: The structured questionnaire mailed to a random population sample included questions on participants' sociodemographic background, medical history, health habits, and recent lifestyle changes. Awareness of the national diabetes programme was also enquired. Data (n = 10 831) from the 2004-2008 postal surveys were used for this investigation. RESULTS: In the FIN-D2D area, 25% (347/1384) of men and 48% (797/1674) of women reported being aware of the programme. In the control area, the proportions were 20% (702/3551) and 36% (1514/4222), respectively. The overall awareness increased among both genders and in all areas during the project period, but the level of awareness was consistently higher in the FIN-D2D area. Female gender and higher age were associated with increasing awareness of the programme in both areas. Self-reported lifestyle changes were more common among women, but associated with the level of awareness of the programme more often among men than women. CONCLUSIONS: The awareness of diabetes and its risk factors increased among men and women in both implementation and control areas during the FIN-D2D project period. The activities of the implementation project may at least partly explain the differences in lifestyle changes between areas, especially among men. The results suggest that health promotion campaigns increase the population awareness about the prevention of chronic diseases and as a result, especially men may be prompted to make beneficial lifestyle changes.

Reduced mortality in dermatitis herpetiformis: a population-based study of 476 patients.

BACKGROUND: Dermatitis herpetiformis (DH) is an extra-intestinal manifestation of coeliac disease and most patients adhere to a life-long gluten free diet (GFD). Increased mortality rates have been reported in coeliac disease but knowledge in DH is scanty. OBJECTIVES: To survey the mortality rate and causes of death in a large cohort of patients with DH. MATERIAL AND METHODS: Patients with DH (n = 476 consecutive patients) diagnosed from 1970 onwards at the Tampere University Hospital were analysed for causes of death during 1971-2010. A questionnaire survey on key aspects of health behaviour was performed in patients with DH and comparisons were made with the Finnish population. RESULTS: The total number of deaths during 9079 person years followed up was 77 whereas 110 were expected. The standardized mortality rate (SMR) for all causes of death was significantly reduced, being 0·70 (95% CI 0·55-0·87), and similar in both sexes. The SMR was equal in the patients with DH with (0·73) and without (0·77) small bowel villous atrophy. The SMR was significantly reduced (0·38) for deaths due to cerebrovascular diseases. The SMR due to lymphoproliferative malignancies was significantly increased (6·86) in the first 5 years of follow-up but not thereafter. The questionnaire survey documented that 97·7% of the patients with DH adhered to a GFD. The patients reported significantly less hypercholesterolaemia and there were fewer current and past smokers compared with the age- and sex-matched control population. CONCLUSIONS: The present long-term follow-up study of DH documented significantly reduced all-cause and cerebrovascular disease mortality. Strict adherence to a GFD, less smoking and hypercholesterolaemia may play a role in the observed health benefit.

Trends of socioeconomic differences in daily vegetable consumption, 1979-2002.

BACKGROUND: Studies from different time periods have shown that consumption of vegetables is more common in higher socioeconomic groups and among women. However, there are only few studies of changes of socioeconomic differences in vegetable consumption over time. Our aim was to determine whether socioeconomic differences, measured by educational level and household income, in daily vegetable consumption have increased, decreased or been stable over the last two decades among Finnish men and women. METHODS: Data on daily consumption of fresh vegetables were derived from repeated annual cross-sectional surveys performed among representative samples of Finnish working aged (15-64 years) population. Data from the years 1979-2002 were linked with data on education and household income from Statistics Finland. Those under 25 years and all students were excluded, giving a total of 69 383 respondents. The main analyses were conducted with logistic regression. RESULTS: Daily consumption of fresh vegetables became overall more prevalent during the study period. Daily consumption of fresh vegetables was more common among those with higher education and higher income during the whole study period. Both educational level and household income differences in daily vegetable consumption slightly narrowed since 1979 among men and women. CONCLUSIONS: Women with high socioeconomic position have been initial trend setters, but the prevalence of daily consumers of vegetables in these groups has not increased since the early 1990s. The prevalence of daily consumption of fresh vegetables has increased more in lower educational and income groups during the 1980s and 1990s along with narrowing socioeconomic differences.

Did Finland's Tobacco Control Act of 1976 have an impact on ever smoking? An examination based on male and female cohort trends.

OBJECTIVE: To examine patterns of ever smoking among Finnish adults by gender and birth cohort from 1978 to 2001, with special emphasis on the possible effects of the 1976 Tobacco Control Act (TCA). METHODS: The data were derived from independent, annual cross sectional postal surveys among 15-64 year olds (n = 91,342), average response rate 75%. For the analyses 13 five year birth cohorts from 1916 to 1980 were constructed. Birth cohort variations in ever regular smoking were first examined graphically, and then logistic models were used to test the impact of the TCA. RESULTS: Among men there was a decrease in smoking from older to younger cohorts. For women an increase in smoking was observed between successive cohorts. A clear decline in the prevalence of ever smokers concurrent with the TCA was found among both men and women. CONCLUSIONS: The smoking behaviour trends across successive birth cohorts suggest the impact of tobacco policy in decreasing smoking initiation in youth. These findings thus support the acceptability and effectiveness of antismoking and smoke free policy measures in society.

Associations between health-related behaviors: a 7-year follow-up of adults.

BACKGROUND: The study examines pairwise associations between smoking, alcohol use, physical activity, dietary behavior and body mass index using long-term follow-up data of Finnish adults. METHODS: Respondents to large nationwide health behavior surveys conducted in 1989/1990 were recontacted in 1997. First, we examined whether each health behavior predicted other behaviors 7 years later. Second, we examined whether changes in each health behavior were accompanied by changes in other behaviors. RESULTS: Smoking at baseline predicted all other health behaviors except body mass index in men. On the other hand, other behaviors tended to predict smoking. Physical inactivity and unhealthy diet were predictive of each other in men. Those with an unhealthy diet at baseline were less likely to be high alcohol users in the follow-up. Baseline body mass index did not predict any of the other behaviors. Concurrent changes in health behaviors involved either smoking or body mass index. Changes in diet and alcohol use were differently related to changes in body mass index in men than in women. CONCLUSIONS: Overall, smoking seemed to play a central role in the associations between health behaviors. Smoking was predictive of most other health behaviors. Concurrent changes in health behaviors related either to smoking or to body weight. The associations between health behaviors were fairly similar for men and women, but the variation in the associations between body mass index and some other health behaviors suggests gender differences in the behavioral response to body weight.

Development of smoking by birth cohort in the adult population in eastern Finland 1972-97.

OBJECTIVE: To analyse the dynamics of smoking prevalence, initiation, and cessation in relation to sex, age, birth cohort, study year, and educational level. DESIGN: Six independent cross-sectional population surveys repeated every five years between 1972 and 1997. SETTING: The provinces of North Karelia and Kuopio in eastern Finland. SUBJECTS: Independent random samples of 18,088 men and 19,200 women aged 25-64 years. Those comprising the oldest birth cohort were born in 1913-17 and those in the youngest were born in 1968-72. RESULTS: Among men the prevalence of smoking decreased over time, but the cohort effect observed in smoking initiation was obscured by the changes in smoking cessation. Differences between the educational categories were small. Among women the prevalence of smoking increased during the study period. This was mainly caused by the less highly educated, in whom smoking initiation clearly increased in successive birth cohorts, but a more moderate cohort effect was also present among the more highly educated women. CONCLUSIONS: In men decreased initiation and increased cessation contributed to the downward trend in smoking prevalence, whereas among women, changes in smoking were mostly caused by augmented initiation in successive birth cohorts. During the study period educational inequalities in smoking widened, as the less highly educated came increasingly to form the smoking population.
