The National FINDIET surveys are carried out every 5 years to monitor dietary habits and nutrient intake of the adult Finnish population. The latest survey was carried out in 2007.

Cross-sectional population-based study. Dietary assessment was carried out using 48 h recall interviews. A picture book of food portions was used to estimate portion sizes and the national Food Composition Database Fineli® to calculate nutrient intakes.

A representative sample taken in five regions in Finland.

A total of 730 men and 846 women aged 24–64 years.

The percentage contribution of fat to the total energy intake was 33 % in men and 31 % in women. The respective percentages for SFA in men and women were 13 % and 12 %, respectively, and 0·4 % for trans fatty acids in both genders. The average intakes of folate, vitamin D and fibre fell below the recommended levels, whereas the average salt intake was somewhat higher than the recommendations. Women’s diet was higher in protein, dietary fibre and sucrose compared to that of men.

According to the FINDIET 2007 Survey, the dietary habits of the adult Finnish population have headed in a positive direction overall. However, although the quality of the fats consumed has continued to improve, and the intake of salt has decreased, they still do not meet the recommended levels of intake. Similarly, the average intakes of folate and vitamin D continue to fall below the recommendations. There is also a need to increase fibre intake and to cut down the intake of sucrose.

The aim of the study is to elucidate differences in adults’ diet by education, and to analyse the associations between dietary facilitators, education and dietary fat quality.

In all, one-third of subjects from the national FINRISK health survey were invited to participate in the FINDIET 2007 Survey. A 48 h dietary interview was used for dietary data and personal background data were collected by the health survey questionnaire.

Representative sample from five regions in Finland in spring 2007.

A total of 1576 adults, participation rate 60 %.

Oil used in cooking differed by education. Instead perception of cardiovascular risk, or the following of a cholesterol-lowering diet, were equal across all educational categories. The diet of men with low education contained less protein and carbohydrates, more fat and more SFA and MUFA than that of highly educated men. The diet of women with low education contained less PUFA, vitamin C and vitamin E than in the highly educated category. High education remained a significant determinant for the lower intake of SFA in men, and for the higher intake of PUFA in women, after adjusting for the determinants and facilitators of dietary behaviour and age. The lower intake of SFA was also associated with following a cholesterol-lowering diet in both genders. In addition to education, the intake of unsaturated fatty acids was determined by the oil used in cooking by women, and by frequent lunches served by caterers for men.

In dietary behaviour, awareness and reporting of cholesterol-lowering diet seem to indicate a tendency to control the intake of saturated fat. Health messages are likely to enhance tools for increasing the intake of PUFA, in addition to reducing the intake of SFA.

To assess to what extent the observed dietary changes and increased use of lipid-lowering medication can explain the almost 20 % decline in serum cholesterol (referring to serum total cholesterol) level observed from 1982 to 2007 in Finland.

Predicted changes of serum cholesterol were calculated by the Keys’ equation assuming the effect of trans fatty acids to be similar to SFA and using the dietary intake data of the national dietary surveys between 1982 and 2007. The effect of medication was estimated based on the information on use of lipid-lowering medication among survey participants. The predicted serum cholesterol levels were compared with observed changes in analysed serum cholesterol levels.

Four cross-sectional population surveys, in 1982, 1992, 2002 and 2007, in the provinces of North Karelia, Northern Savo and Southwestern Finland.

A total of 2325 men and 2638 women aged 26–64 years selected randomly from the national population register for the four surveys.

Changes in dietary fat quality and cholesterol intake explain 0·70 mmol/l (65 %) of the decrease in men and 0·65 mmol/l (60 %) of the decrease in women in all subjects. Decline in dietary SFA intake is the main explanatory factor (47 % in men and 41 % in women) for the changes. The impact of lipid-lowering medication on observed cholesterol levels was found to be 16 % among men and 7 % among women.

The decrease in serum cholesterol levels in Finland can be explained mainly by dietary changes, especially changes in fat quality. The effect of lipid-lowering medication is less significant.

To describe the diet of a population of pregnant Finnish women over a period of 7 years, with special attention paid to seasonal fluctuations in food consumption and nutrient intake.

A validated 181-item FFQ was applied retrospectively, after delivery, to assess the maternal diet during the 8th month of pregnancy.

Type 1 Diabetes Prediction and Prevention Nutrition Study Cohort.

The cohort comprised a total of 4880 women who had newly delivered during the years 1997–2004, with the offspring carrying increased genetic risk for type 1 diabetes mellitus.

Over the study period, the proportion of energy derived from fat decreased while the intake from protein and carbohydrate increased. The intake of vitamin D increased from food sources. Seasonal variation was observed in the mean daily consumption of vegetables, fruits and berries and cereals. Intake of dietary fibre, total fat, MUFA, vitamins A, D, E and C, folate and iron also showed seasonal fluctuation.

These results show an overall positive trend in the diet of pregnant Finnish women through the study years. However, there is still room for improvement, particularly in the types of dietary fats. Although food fortification with vitamin D since 2003 was reflected in the increased intake of vitamin D from foods, the mean intake levels still fell below the recommendations. Seasonal changes in food consumption were observed and related to corresponding fluctuations in nutrient intakes. The mean folate intake fell below the recommendation throughout the year.

To study food consumption and nutrient intake in Finnish children aged 1–6 years and to assess the effect of age and sex on food consumption and nutrient intake.

Cross-sectional samples of children participating in the Type 1 Diabetes Prediction and Prevention (DIPP) birth cohort study in Finland.

The study population comprised healthy children recruited in the nutrition study within the DIPP study in 1998–2003. Three-day food records (2535 in total) from 1-, 2-, 3-, 4- and 6-year-old children were kept between the years 2003 and 2005.

The energy-adjusted consumption of fruits and berries, cereal products, infant formulas and meat dishes was higher and the consumption of vegetables, salads, breads, dairy products, fat spreads, drinks, sweets and sugar was lower among 1-year-old children than older age groups (P for all <0·05). The mean daily energy intake increased with age and was higher among boys than girls in all age groups, except among the 2-year-olds (P for all <0·05). The diet of the 2–6-year-old children contained too much saturated fat and sucrose, and too little PUFA compared with the current Nordic Nutrition Recommendations. The intakes of most vitamins and minerals met the recommendations. However, the intakes of vitamin D, E and iron fell below the recommended levels. The nutrient density of the diet decreased after the age of 1 year at the time that the children adapted to the regular family diet.

In order to improve the diet of young children, it is essential to evaluate the diet of the whole family.

To assess and compare the food consumption and nutrient intake between 3-year-old children cared for at home full-time and those attending day care outside the home. Nutrient intake on weekdays and weekends was also studied.

Cross-sectional sample of children invited to the nutrition study within the Type 1 Diabetes Prediction and Prevention (DIPP) birth cohort born in 2001. Families returned 3-d food record completed close to the child’s third birthday.

A total of 471 pre-school children aged 3 years of whom 285 had only been cared for at home during the recording time and 186 had attended day care outside the home.

Among the children cared for outside the home, there were more consumers of recommendable foods as fresh vegetables, fruits, berries, rye bread, fish, skimmed milk and vegetable margarines, than among those cared for at home. The day-care group had higher intake of protein, dietary fibre, thiamine, potassium and magnesium, and lower intake of sucrose compared with the group cared for at home. Adjustment for sociodemographic factors did not change the results. In all children, food consumption was more varied on weekdays compared with weekends. On weekdays, children had higher intake of dietary fibre and protein and lower intake of sucrose compared to weekends.

The type of day care was associated with food consumption and nutrient intake among pre-school children and hence might have an impact on their nutrition and health. The diet of the children attending day care outside the home was more balanced and closer to the national recommendations.

To evaluate food and nutrient intake and especially eating during the school day among Finnish secondary-school pupils.

Cross-sectional study. Data were collected using a structured questionnaire mailed to home and by 48 h dietary recall interviews performed at schools in 2007.

Twelve schools in three cities in Finland.

The seventh grade pupils (a total of 1469 at the mean age of 13·8 years). Questionnaire data were available from 726 pupils and dietary data from a subgroup of 40 % (n 306).

According to the questionnaire data, 40 % of the girls and 28 % of the boys reported eating fresh vegetables daily and the respective figures for fruit were 32 % and 23 %. Altogether, 71 % of the adolescents reported having school lunch every day. The average intake of sucrose was higher and the average intakes of fibre, iron, folate and vitamin D were lower than recommended. School lunch provided around 20 % of daily energy intake, while the recommended daily energy intake level is one-third. However, the school lunch as consumed was nutritionally superior to the other daily meals. Snacks provided 41 % of the daily energy. The most common sources of sucrose were sugary drinks.

Low consumption of fruit and vegetables and abundant consumption of sucrose-rich drinks and snacks are the main problems in the diet of Finnish adolescents. The nutritional quality of the school lunch is good, but the supply of healthy snacks must be improved in schools. Schools can promote healthy eating habits by making healthy choices easy during the school day.

To decrease the intake of sucrose, increase the intake of fibre and the consumption of fruit and vegetables among secondary-school pupils.

Intervention study among eighth grade pupils during one school year. Data were collected by questionnaires and from a subgroup of pupils by 48 h dietary recall at baseline in spring 2007 and after the intervention in 2008.

Twelve secondary schools were randomly allocated to intervention (IS) and control schools (CS) within three cities. Intervention included nutrition education and improvement of the food environment focusing particularly on the quality of snacks at school.

A total of 659 pupils completed the questionnaires and the dietary recall was obtained from 287 pupils both at baseline and follow-up.

The frequency of consumption of rye bread increased (P = 0·03) and that of sweets decreased (P = 0·006) among girls in the IS. The intake of sucrose fell among IS pupils, from 12·8 % to 10·5 % of the total energy intake (P = 0·01). Intake of fruit (g/MJ) remained the same in IS, whereas it decreased in CS (P = 0·04).

Sugar intake can be lowered by improving the quality of snacks, but it is more difficult to increase fibre intake and fruit and vegetable consumption unless the content of school lunches can be modified. It is the responsibility of the adults working in schools to create a healthy environment and to make healthy choices easy for pupils.

Eating habits of Finns have improved dramatically in 40 years. The proportion of fat in the diet has decreased and vegetable and fruit consumption increased. Knowledge of Finnish young men’s dietary habits is limited. The aim was to assess food choices and quality of diet among young men and to analyse how background and health behaviour factors explain it.

In 2007, data on eating habits, sociodemographic background factors and health behaviours of 17–21-year-old men (n 2905) entering military service were collected by self-administrated questionnaire. Two indexes – core food index (CFI) and extra food index (EFI) – were formed to describe daily and redundant snacking-type eating, respectively. Associations of background factors and health behaviours on the indexes were analysed by general linear modelling.

In all, 13 % consumed fruits and berries daily and 8 % consumed vegetables, whereas 24 % consumed pizza and 19 % consumed hamburgers more than once a week. CFI increased with educational level (P < 0·001) and was explained by background and health behaviour (smoking, physical activity and eating breakfast). EFI was inversely associated with BMI (P < 0·001) and explained by health behaviour: (smoking, physical activity, drinking beer and eating breakfast).

These results indicate that in early adulthood, eating habits cluster with other health behaviours among men. In this age group, education is associated with core food but not with extra food eating habits. Furthermore, seasonal variation is seen in both types of eating. When promoting healthy eating, a distinction between core foods and extra foods by using feasible indexes will be helpful in targeting the efforts.

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.

The study summarises mainly basic reports and studies concerning catering services conducted in Finland based on nationally representative population surveys.

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.

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.

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.

The prevalence of type 2 diabetes has been increasing in Finland, in parallel with a gradual increase in overweight and obesity during the past decades. The expanding prevalence of type 2 diabetes brings along complications, most importantly CVD. Therefore, it is extremely important to implement activities to prevent type 2 diabetes.

In the present paper, the clinical evidence for the prevention of type 2 diabetes is presented with the Finnish diabetes prevention study. In addition, the paper discusses the practical implementation of prevention of type 2 diabetes using three different types of prevention programmes as examples: FIN-D2D, including risk-screening and repeated consultation in primary health-care; FINNAIR, a workplace-targeted intervention project involving airline employees; and the good ageing in Lahti region (GOAL) programme, a community-based prevention programme.

FIN-D2D, the FINNAIR project and the GOAL programme have shown that screening for type 2 diabetes risk and implementing large-scale lifestyle intervention in primary health-care are feasible. However, the crucial questions still are whether it is possible to replicate the results concerning effectiveness of lifestyle intervention in primary and occupational health-care systems. Furthermore, it remains to be shown whether it is possible to achieve the same results in different health-care settings, cultures, regions and age groups, especially in adolescents and young adults among whom the increase in the incidence has been the highest. In addition, the importance of co-operation among all sections of society, citizens’ awareness of healthy lifestyles and the social inequalities in health must be emphasised because the diabetes epidemic cannot be solved only by concentrating on preventive actions carried out by health-care systems.
