Abstract
Cardiovascular risk factors and their association with diet were examined in Saami (Lapp) and Finnish reindeer herders (total sample size 2705). The Saami men showed lower systolic blood pressure (130 mmHg) than the Finns (137 mmHg), higher serum total cholesterol (6.92 vs. 6.51 mmol/l) and triglycerides (1.32 vs. 1.11 mmol/l), and more Saami than Finnish men were smokers (34% vs. 27%). Subjects eating reindeer meat daily showed serum cholesterol 0.6 mmol/l higher than those who did so once a month or more rarely, the association being independent of age, season, body mass index, or consumption of coffee, milk, bread, fish, or alcohol. The high content of antioxidants of the Saami diet might explain why cardiovascular diseases are relatively uncommon in the Saami area despite the adverse risk factor pattern.

Abstract
The aim of the present work was to study, using a questionnaire, at which ambient temperature the forestry workers subjectively experience the disadvantages caused by cold. The disadvantages were classified according to criteria of thermophysiology, physical performance, and health. Three levels were used: discomfort, performance degradation, and health problems. The questionnaire was mailed to 490 forestry workers, 347 (71%) of whom responded. The results show that workers (who had experienced cold as harmful moderately often or more frequently) experienced cold as discomfortable on average at -19.4 ± 7.0 degrees C (mean ± SD). Performance degradation was experienced at -23.3 ± 5.7 degrees C and health problems at -24.7 ± 6.7 degrees C. Similar problems were experienced, on average, at a 1 degree C higher temperature traveling to work and from work, and a 4 degree C higher temperature during pauses.

Abstract
BACKGROUND: Exposure to cold weather increases blood pressure (BP) and may aggravate the symptoms and influence the prognosis of subjects with a diagnosis of hypertension. We tested the hypothesis that subjects with hypertension alone or in combination with another cardiovascular disease (CVD) experience cold-related cardiorespiratory symptoms more commonly than persons without hypertension. This information is relevant for proper treatment and could serve as an indicator for predicting wintertime morbidity and mortality.
METHODS: A self-administered questionnaire inquiring of cold-related symptoms was obtained from 6591 men and women aged 25-74 yrs of the FINRISK Study 2002 population. BP was measured in association with clinical examinations. Symptom prevalence was compared between subjects with diagnosed hypertensive disease with (n = 395) or without (n = 764) another CVD, untreated diagnosed hypertension (n = 1308), measured high BP (n = 1070) and a reference group (n = 2728) with normal BP.
RESULTS: Hypertension in combination with another CVD was associated with increased cold-related dyspnoea (men: adjusted odds ratio 3.94, 95% confidence interval 2.57-6.02)/women: 4.41, 2.84-6.86), cough (2.64, 1.62-4.32/4.26, 2.60-6.99), wheezing (2.51, 1.42-4.43/;3.73, 2.08-6.69), mucus excretion (1.90, 1.24-2.91/2.53, 1.54-4.16), chest pain (22.5, 9.81-51.7/17.7, 8.37-37.5) and arrhythmias (43.4, 8.91-211/8.99, 3.99-20.2), compared with the reference group. Both diagnosed treated hypertension and untreated hypertension and measured high BP resulted in increased cardiorespiratory symptoms during the cold season.
CONCLUSION: Hypertension alone and together with another CVD is strongly associated with cold-related cardiorespiratory symptoms. As these symptoms may predict adverse health events, hypertensive patients need customized care and advice on how to cope with cold weather.

Abstract
In Finland, mortality increases steeply in autumn, reaches a peak during the Christhmas holidays and declines slowly towards a trough in August. The relative excess in daily mortality (peak vs. trough) is 30% for coronary heart disease, 40% for cerebral vascular accidents and 90% for diseases of the respiratory organs. There is a secondary peak in Midsummer, especially in coronary deaths of working aged men. Mortality is lowest at mean daily temperature of +14 degrees C, and it increases slowly with falling temperature and steeply with increasing temperature. An estimated 2000-3000 extra deaths occur in Finland during the cold season, most of which are people aged 65 years and over but 20% at working age. The number of people dying from high temperatures (over +14 degrees C) in this country in a normal year is 100-200. Heat deaths are mostly certified as being due to cardiovascular or respiratory conditions. Exposure to cold air causes a rise in blood pressure and haemoconcentration which lead to increased tendency to vascular thromboses. In hot weather, haemoconcentration due to sweating and perspiration increases blood viscosity and the risk of thrombosis. Both cold and heat are significant public health hazards which should be taken into account in health care and education of health professionals.

Abstract
OBJECTIVES: To assess heat related mortalities in relation to climate within Europe. DESIGN: Observational population study. Setting: North Finland, south Finland, Baden-Württemberg, Netherlands, London, north Italy, and Athens. SUBJECTS: People aged 65-74. Main outcome measures: Mortalities at temperatures above, below, and within each region's temperature band of minimum mortality. RESULTS: Mortality was lowest at 14.3-17.3 degrees C in north Finland but at 22.7-25.7 degrees C in Athens. Overall the 3 degrees C minimum mortality temperature bands were significantly higher in regions with higher than lower mean summer temperatures (P=0.027). This was not due to regional differences in wind speeds, humidity, or rain. As a result, regions with hot summers did not have significantly higher annual heat related mortality per million population than cold regions at temperatures above these bands. Mean annual heat related mortalities were 304 (95% confidence interval 126 to 482) in North Finland, 445 (59 to 831) in Athens, and 40 (13 to 68) in London. Cold related mortalities were 2457 (1130 to 3786), 2533 (965 to 4101), and 3129 (2319 to 3939) respectively. CONCLUSIONS: Populations in Europe have adjusted successfully to mean summer temperatures ranging from 13.5 degrees C to 24.1 degrees C, and can be expected to adjust to global warming predicted for the next half century with little sustained increase in heat related mortality. Active measures to accelerate adjustment to hot weather could minimise temporary rises in heat related mortality, and measures to maintain protection against cold in winter could permit substantial reductions in overall mortality as temperatures rise.

Abstract
It has been suggested, that the inhabitants of northern European regions, who experience little cold-related mortality, protect themselves outdoors by wearing more clothing, at the same temperature, than people living in southern regions where such mortality is high. Outdoor clothing data were collected in eight regions from 6583 people divided by sex and age group (50-59 and 65-74 years). Across Europe, the total clothing worn (as assessed by dry thermal insulation and numbers of items or layers) increased significantly with cold, wind, less physical activity and longer periods outdoors. Men wore 0.14 clo (1 clo = 0.115 m2 K W-1) more than women and the older people wore 0.05 clo more than the younger group (both P

Abstract
BACKGROUND: Few epidemiological studies exist on food-associated symptoms and allergies in large unselected child populations. AIMS: To describe the design, methods and participation rate of the South Karelian Allergy Research Project (SKARP), a population-based epidemiological study on food-associated symptoms and physician-diagnosed food allergies. METHODS: The study population of 5,973 children born between 2001 and 2006 and resident in the province of South Karelia, Finland, was identified from the nationwide population register. The parents received a questionnaire to be returned at their child's annual visit to the child health clinic, where supplementary interviews were performed. Results of allergy tests (skin prick tests, immunoglobulin E antibodies and open food challenges) performed on participants and non-participants were collected from the relevant health care units in the area. RESULTS: Participation rates in the questionnaire study were 54% (644/1,194) among the parents of neonates and 69% (3308/4,779) among those of the children aged 1 to 4 years. Cooperation with the child health clinics and mailing of a reminder questionnaire improved participation by 8 and 10 percentage points, respectively. The final participation rate seemed to be unaffected by whether the child had or had not been tested for suspected allergy. CONCLUSIONS: A reasonably good participation rate and almost complete coverage of allergy tests were achieved thanks to successful cooperation with the child health clinics and test laboratories. This baseline study forms a representative database to estimate the occurrence of food-associated symptoms, physician-diagnosed food allergies and allergy testing in the general population.
