Longitudinal trends in consumption of vegetables and fruit in Finnish children in an atherosclerosis prevention study (STRIP).

OBJECTIVE: To assess prospectively the consumption of fruit and vegetables and its' correlation to the parental consumption in boys and girls taking part in an atherosclerosis prevention study (Special Turku Coronary Risk Factor Intervention Project for Children (STRIP) study). HYPOTHESIS: Nutrition counselling focused on cardiovascular health effects vegetable and fruit consumption. DESIGN: A prospective, randomised, clinical trial. SUBJECTS: Children were recruited to the STRIP study between 1989 and 1992. At the age of 7 months, children were randomised to the intervention (n = 540) or the control group (n = 522) and were followed up until the age of 11 years. INTERVENTION: Families in the intervention group have, since randomisation, received biannual individualised dietary counselling aimed at reduction of cardiovascular risk factors, especially saturated fat intake. Food records were used to assess fruit and vegetable consumption of children and parents. RESULTS: The percentage of total energy intake provided by fruit and vegetables decreased when the children grew older (P for age <0.001). The 1- to 10-year-old intervention boys consumed more vegetables (mean difference 3.18 g/day; CI 1.48-4.86; P < 0.001) and fruit (mean difference 10.1 g/day; CI 5.28-14.94; P < 0.001) than did the control. Mother's consumption correlated with the consumption of their daughters and sons, whereas father's consumption correlated only with the consumption of their sons. CONCLUSIONS: Finnish children taking part in the atherosclerosis prevention study had a remarkably low fruit and vegetable consumption, which furthermore decreased with age. The children's consumption correlated with the parental consumption, except between boys and mothers. A slight intervention effect was present only among boys.

Consistent dietary patterns identified from childhood to adulthood: the cardiovascular risk in Young Finns Study.

Dietary patterns are useful in nutritional epidemiology, providing a comprehensive alternative to the traditional approach based on single nutrients. The Cardiovascular Risk in Young Finns Study is a prospective cohort study with a 21-year follow-up. At baseline, detailed quantitative information on subjects' food consumption was obtained using a 48 h dietary recall method (n 1768, aged 3-18 years). The interviews were repeated after 6 and 21 years (n 1200 and n 1037, respectively). We conducted a principal component analysis to identify major dietary patterns at each study point. A set of two similar patterns was recognised throughout the study. Pattern 1 was positively correlated with consumption of traditional Finnish foods, such as rye, potatoes, milk, butter, sausages and coffee, and negatively correlated with fruit, berries and dairy products other than milk. Pattern 1 type of diet was more common among male subjects, smokers and those living in rural areas. Pattern 2, predominant among female subjects, non-smokers and in urban areas, was characterised by more health-conscious food choices such as vegetables, legumes and nuts, tea, rye, cheese and other dairy products, and also by consumption of alcoholic beverages. Tracking of the pattern scores was observed, particularly among subjects who were adolescents at baseline. Of those originally belonging to the uppermost quintile of pattern 1 and 2 scores, 41 and 38 % respectively, persisted in the same quintile 21 years later. Our results suggest that food behaviour and concrete food choices are established already in childhood or adolescence and may significantly track into adulthood.

Longitudinal changes in diet from childhood into adulthood with respect to risk of cardiovascular diseases: The Cardiovascular Risk in Young Finns Study.

OBJECTIVE: To assess nutrient intakes relevant in the prevention of cardiovascular diseases (CVD) among young adults in Finland and to find past and present determinants of quality of diet. DESIGN: Prospective study, 21 years of follow-up. SETTING: The Cardiovascular Risk in Young Finns Study, Finland. SUBJECTS: At baseline in 1980: 3569 children aged 3-18 y participated (83% of those invited), and every second of them (1780) were selected to the dietary study. At follow-ups in 1986 and 2001: 1200 and 1037 of the original sample, respectively, participated. METHODS: Food consumption was assessed using 48-h dietary recall. Intakes in 2001 were compared with those obtained in 1980 and 1986. Nutrients selected for further examination were those implicated in the risk of CVD: saturated, monounsaturated, polyunsaturated and n-3 fatty acids, fibre and salt. An index describing the quality of adulthood diet was constructed. Multivariate logistic regression was used to identify independent childhood and adulthood determinants of the quality index. RESULTS: The average intakes showed substantial changes since 1980. Intakes of fat and saturated fat had decreased, while the consumption of vegetables and fruit had increased. However, a great disparity was present between the recommended levels and actual intakes for many of the nutrients, particularly salt, saturated fat and fibre. Intake of fat and consumption of vegetables in childhood and physical activity in adulthood were important health behavioural determinants of the cardiovascular quality of the adult diet. Socio-demographic factors, including education of the subject and their parents, had no significant associations with diet. CONCLUSIONS: While intakes of energy and nutrients have changed favourably in Finnish young adults between 1980 and 2001 with regard to the risk of CVD, they are still far from recommended levels. Childhood diet is a significant determinant of adult diet even after 21 y. SPONSORSHIP: This study was supported by the Academy of Finland (grant 77841) and Juho Vainio Foundation.

Diet and 20-year chronic obstructive pulmonary disease mortality in middle-aged men from three European countries.

OBJECTIVE: To investigate the relation of baseline antioxidant, fruit, vegetable and fish intake with 20 y chronic obstructive pulmonary disease (COPD) mortality in middle-aged men from three European countries. DESIGN: Prospective study (1970-1990). SETTING: Five population-based cohorts of middle-aged men from Finland, Italy and The Netherlands. SUBJECTS: A total of 2917 men aged 50-69 y at baseline. METHODS: Baseline information on diet was collected using the cross-check dietary history method. After 20 y of follow-up the underlying cause of death of those who died was established centrally. Survival analyses were performed using the Cox Proportional Hazards Model. RESULTS: After adjustment for age, smoking and country, we observed an inverse trend (P-trend <0.05) of 20 y COPD mortality across tertiles of fruit and vitamin E intake. No trend was observed for vegetables, fish, vitamin C and beta-carotene. When modelled continuously, a 100 g increase in fruit intake was associated with a 24% lower COPD mortality risk (RR=0.76, 95% CI=0.60-0.92). For vitamin E intake (per 5 mg) the RR was 0.77 (95% CI=0.55-1.06), after adjustment for age, smoking and country. Additional adjustment for body mass index, total energy intake and alcohol consumption reduced the RR to 0.86 (95% CI=0.69-1.07, P=0.12) for fruit and 0.93 (95% CI=0.65-1.33) for vitamin E. CONCLUSIONS: Our results suggest a protective effect of fruit and possibly vitamin E intake against COPD. No effect was observed for intake of vitamin C, beta-carotene, vegetables and fish.

Validity and reproducibility of a food frequency questionnaire for pregnant Finnish women.

The authors developed a self-administered 181-item food frequency questionnaire (FFQ) to assess dietary intake during pregnancy for Finnish women from August 1995 to July 1996. In the validation study (n = 113), the data that were collected by using two 5-day food records completed during the eighth month of pregnancy were compared with FFQ data. The intake of foods and nutrients was higher as determined by FFQ than that assessed using food records. Pearson correlation coefficients for nutrients, after adjustment for energy, ranged from 0.19 (vitamin E) to 0.70 (thiamin) and, for foods, from 0.03 (high-fat milk) to 0.84 (low-fat milk). Energy adjustment improved the correlations for nutrients. Correction for attenuation improved correlations for both foods and nutrients. On average, 70% of the foods and 69% of the nutrients fell into the same or adjacent quintiles, according to the FFQ and the food record. In the reproducibility study, 111 women completed the FFQs twice at a 1-month interval. The intraclass correlation coefficients for nutrients ranged from 0.42 (ethanol) to 0.72 (sucrose, riboflavin, and calcium), and for foods, they ranged from 0.44 (ice cream) to 0.91 (coffee). The authors conclude that the FFQ has an acceptable reproducibility and represents a useful tool for categorizing pregnant women according to their dietary intake.

Cohort analysis of fruit and vegetable consumption and lung cancer mortality in European men.

Our aim was to examine the relationship between fruit and vegetable consumption and lung cancer mortality in a cohort of European males. Around 1970, dietary intake of Finnish, Italian and Dutch middle-aged men was assessed using a cross-check dietary history. Complete baseline information was available for 3,108 men, of whom 1,578 were baseline smokers. We used Cox proportional hazard analyses to calculate risk estimates for the consumption in country-specific tertiles on lung cancer in smokers. During 25 years of follow-up, 149 lung cancer deaths occurred in the smokers. Fruit consumption was inversely associated with lung cancer mortality among smokers; compared with the lowest, adjusted RRs for the intermediate and highest tertiles were 0.56 (0.37-0.84) and 0.69 (0.46-1.02), p-trend 0.05. Only in the Dutch cohort was this association statistically significant [adjusted relative risks (RRs) 1.00, 0.33 (0.16-0.70) and 0.35 (0.16-0.74), p-trend 0.004]. In Finland lung cancer risk was lower with higher fruit intake but not significantly, whereas in Italy no association was observed. Stratifying on cigarette smoking intensity (non, light and heavy) revealed an inverse association in the heavy smokers only [adjusted RRs (95% confidence intervals [CI]) 1; 0.47 (0.26-0.84); 0.40 (0.20-0.78)). Vegetable consumption was not related to lung cancer risk in smokers. However, analyses stratified on cigarette smoking intensity gave some indication for a lower lung cancer risk with higher intake. In conclusion, in this prospective analysis among European smoking men, fruit intake was inversely related to lung cancer mortality. This association was confined to heavy cigarette smokers.

Diet, serum fatty acids, and atopic diseases in childhood.

BACKGROUND: The reasons behind the reported increase in the occurrence of childhood atopic sensitization rates are unclear. We wanted to evaluate the association between dietary fats, serum fatty acids, and the occurrence and development of atopic diseases. METHODS: From a longitudinal database of a population-based sample, 231 sex- and age-matched pairs in 1980 and 154 pairs in 1986 were chosen, between whom we compared the dietary data, serum fatty acid composition, and occurrence of atopic diseases. The same variables were also compared between those who developed atopic disease later and those who did not during the 9-year follow-up. RESULTS: Examination of the dietary data in 1980 for those who had developed atopic disease compared with those who had remained healthy showed that the atopic children had used less butter before the expression of atopy. According to the cross-sectional data, the children with atopic disease consumed more margarine (mean 8.6 vs 7.3 [P = 0.04]), and less butter (mean 9.4 vs 11.6 g/1000 kcal [P = 0.002]), than the nonatopic children in 1980. Differences supporting these dietary findings were similarly found in the serum fatty acid data. CONCLUSION: The diet of the atopic children differed from that of the nonatopic children in the consumption of polyunsaturated fat.

Alcohol consumption in relation to 20-year COPD mortality and pulmonary function in middle-aged men from three European countries.

Alcohol consumption shows a U-shaped relation with all-cause and cardiovascular mortality. To determine whether a similar relation exists between alcohol and chronic obstructive pulmonary disease mortality, we analyzed data on alcohol consumption in 1970 and 20-year mortality from chronic obstructive pulmonary disease among 2,953 middle-aged men from Finland, Italy, and the Netherlands. We also studied alcohol consumption in relation to pulmonary function (FEV1 or FEV0.75) at baseline. We used regression models adjusted for age, height (for pulmonary function only), body mass index, smoking habits, energy intake, and country. A smoothed spline-plot showed a U-shaped relation between alcohol and chronic obstructive pulmonary disease mortality. Compared with non-drinkers and occasional drinkers, the relative risk of chronic obstructive pulmonary disease mortality was 0.60 (95% CI = 0.33-1.09) in light drinkers (> 1 drink per week, < or = 3 drinks per day) and 1.25 (95% CI = 0.47-3.31) in moderate-to-heavy drinkers. Pulmonary function was lower in non-drinkers compared with occasional and light drinkers in Finland (75 ml, 95% CI = -2 to 151) and the Netherlands (93 ml, 95% CI = 0-186) and lower in very heavy (> 12 drinks per day) compared with moderate-to-heavy drinkers in Italy (99 ml, 95% CI = 9-189). In conclusion, we observed a U-shaped curve between alcohol consumption and 20-year chronic obstructive pulmonary disease mortality in middle-aged men that was supported by cross-sectional data on alcohol and pulmonary function.

Changes in food habits in families with a newly diagnosed child with type 1 diabetes mellitus.

Dietary recommendations for children with type 1 diabetes mellitus (DM) are in line with the recommendations for the general population and applicable to the whole family. We review what is known about the food habits of non-diabetic family members and present original data on dietary changes in families with a child with DM. Some studies suggest that family members eat mostly the same food as the affected child. In a Finnish study of siblings of children with DM, favourable changes were observed after diagnosis in the type of milk and fat used. In a study of young children with DM, family members increased their consumption of skim milk, low-fat cheese and low-fat cold meat cuts. The consumption frequencies of fruit and vegetables increased. In conclusion, family members of a child with DM are willing to change their food habits towards the recommended diet. Dietary advice should be directed to the whole family from the very beginning.

Fish consumption and coronary heart disease mortality in Finland, Italy, and The Netherlands.

Fish consumption seems to protect against death from coronary heart disease (CHD). If this association is due to n-3 polyunsaturated fatty acids, especially fatty fish may be responsible for this protective effect. The association between total, lean, and fatty fish consumption and the risk of CHD mortality was examined in 1,088 Finnish, 1,097 Italian, and 553 Dutch men participants in the Seven Countries Study who were aged 50-69 years and free of CHD around 1970. After 20 years of follow-up, 242 (22.2%) men in Finland, 116 (10.6%) men in Italy, and 105 (19.0%) men in the Netherlands had died of CHD. Cox proportional hazards analysis showed no association between total fish consumption and CHD mortality. After adjustments were made for age, body mass index, smoking, energy intake, and relevant dietary variables, the pooled relative risk for the highest quartile of total fish compared with no fish consumption in the three countries was 1.08 (95% confidence interval: 0.76, 1.53). Lean fish consumption also was not associated with CHD mortality in any country. Fatty fish compared with non-fatty-fish consumption was associated with lower CHD mortality; the adjusted, pooled relative risk for fatty fish consumers was 0.66 (95% confidence interval: 0.49, 0.90). These data suggest that especially fatty fish is protective against CHD mortality.

Comparison of diets of diabetic and non-diabetic elderly men in Finland, The Netherlands and Italy.

OBJECTIVE: To evaluate whether dietary recommendations for subjects with diabetes are met among Finnish, Dutch and Italian elderly men with diabetes, and whether the diets of diabetic and non-diabetic men differ in these three countries. DESIGN: A dietary survey using cross-check dietary history method. A cross-sectional comparison. SETTING: Thirty-year follow-up of survivors from the Finnish, Dutch and Italian cohorts of the Seven Countries Study. SUBJECTS: 227 elderly men from Finland, 537 from The Netherlands, and 417 from Italy, of whom 8-9% had diabetes. MAIN RESULTS: The diets of non-diabetic men from the three countries differed markedly from each other. In all three countries diabetic men consumed less added sugar than non-diabetic men. In Italy, in addition, diabetic men consumed more fruits and berries and vegetables. The Dutch diabetic men ate relatively more cereal products, fruits and berries, milk and milk products, cheese, and meat and meat products and drank less alcoholic beverages than non-diabetic men. The diet of both diabetic and non-diabetic Finnish and Dutch men was characterized by high fat content (41% and 40% of energy, respectively). The fat content of the diet was even higher for diabetic than non-diabetic men in Finland and The Netherlands, but not in Italy. The fibre content of the diet was the highest among Dutch men and diabetic men received more dietary fibre than non-diabetic men in The Netherlands and Italy, but not in Finland. The diet of diabetic and non-diabetic Finnish men differed little from each other and was characterized by high nutrient density of several vitamins and minerals. The proportion of protein of energy intake was higher among diabetic than non-diabetic Dutch and Italian men. CONCLUSIONS: The diet of the diabetic men from Finland, the Netherlands, and Italy resembled more the diet of non-diabetic men from the respective countries than the diet of diabetic men from the other countries. In the diet of Italian diabetic men, the proportions of fat, saturated fatty acids and carbohydrates were nearest the recommended levels.

Two year prospective dietary survey of newly diagnosed children with diabetes aged less than 6 years.

The food consumption of 38 children newly diagnosed with diabetes aged < 6 years at diagnosis was assessed by 5 day food records. During the 2 year follow up, the proportion of the total energy intake made up of protein decreased from 20% to 18%, that of carbohydrates from 54% to 52%, and that of fat increased from 26% to 30%. The energy intake from sucrose (3%) did not change. In addition, There was a small decrease in the intake of fibre and several vitamins and minerals. One year after diagnosis, the diet of diabetic children was compared with that of 66 age, sex, and social status matched control children. More energy was derived from protein (19% v 15%) and carbohydrates (53% v 50%), and less from fat (28% v 35%), especially from saturated fatty acids (11% v 15%), and sucrose (3% v 16%) in the diet of children with diabetes compared with that of control children. The higher intakes of several vitamins and minerals reflected the higher nutrient density of the diet of children with diabetes. Therefore, the diet of young children with diabetes met the dietary recommendations for subjects with diabetes. Only the protein content of the diet was higher than necessary.

Cow's milk consumption, HLA-DQB1 genotype, and type 1 diabetes: a nested case-control study of siblings of children with diabetes. Childhood diabetes in Finland study group.

The evidence for the putative role of cow's milk in the development of type 1 diabetes is controversial. We studied infant feeding patterns and childhood diet by structured questionnaire (n = 725) and HLA-DQB1 genotype by a polymerase chain reaction-based method (n = 556) in siblings of affected children and followed them for clinical type 1 diabetes. In a nested case-control design in a population who had both dietary and genetic data available, we selected as cases those siblings who progressed to clinical diabetes during the follow-up period (n = 33). For each case, we chose as matched control subjects siblings who fulfilled the following criteria: same sex, age within 1 year, not from the same family, the start of the follow-up within 6 months of that of the respective case, and being at risk for type 1 diabetes at the time the case presented with that disease (n = 254). The median follow-up time was 9.7 years (range 0.2-11.3). Early age at introduction of cow's milk supplements was not significantly associated with progression to clinical type 1 diabetes (relative risk adjusted for matching factors, maternal education, maternal and child's ages, childhood milk consumption, and genetic susceptibility markers was 1.60 [95% CI 0.5-5.1]). The estimated relative risk of childhood milk consumption for progression to type 1 diabetes was 5.37 (1.6-18.4) when adjusted for the matching and aforementioned sociodemographic factors, age at introduction of supplementary milk feeding, as well as for genetic susceptibility markers. In conclusion, our results provide support for the hypothesis that high consumption of cow's milk during childhood can be diabetogenic in siblings of children with type 1 diabetes. However, further studies are needed to assess the possible interaction between genetic disease susceptibility and dietary exposures in the development of this disease.

Hypersensitivity to gold in gold sodium thiomalate-induced dermatosis.

Gold compounds are widely used in the treatment of rheumatoid arthritis. Mucocutaneous side-effects leading to the discontinuation of medication are common with these drugs. We investigated whether allergic mechanisms are involved in dermatosis induced by gold sodium thiomalate (GSTM). Thirteen gold dermatosis patients, 15 arthritis patients without any side-effects from GSTM and 11 healthy controls participated in the study. Venous blood lymphocytes from these subjects were cultured with GSTM and gold sodium thiosulphate (GSTS) in the lymphocyte proliferation test (LPT). In some cases, interferon-gamma-producing cells were enumerated in vitro (T-cell ELISpot). The subjects were also patch-tested with GSTM and GSTS. The LPT to either GSTM, GSTS or both was positive in 12 of 13 patients with gold dermatosis. In the arthritis patient group without side-effects from gold, the LPT gave two false-positive results and in the healthy control group the LPT was falsely positive with one subject. T-cell ELISpot was positive in four of six gold dermatosis patients and negative in the arthritis and healthy control groups. Only one patient who also developed contact dermatitis from gold jewellery was positive to gold in the patch test. These results indicate that gold dermatosis is mediated, at least in part, by allergic mechanisms and that the LPT is of value in the diagnosis of gold dermatosis.

Dietary factors and pulmonary function: a cross sectional study in middle aged men from three European countries.

BACKGROUND: Results of epidemiological studies relating individual dietary factors to chronic obstructive pulmonary disease (COPD) are inconsistent. To evaluate the cross sectional association of dietary factors with pulmonary function, data were collected from middle aged men in three European countries. METHODS: The data were collected in the 1960s in Finland (n = 1248), Italy (n = 1386), and the Netherlands (n = 691). Dietary intake was estimated using the cross-check dietary history method. Forced expiratory volume (FEV(0.75) or FEV(1), here called FEV) was measured by spirometry. Associations were adjusted for age, height, smoking, body mass index (BMI), alcohol consumption, and energy intake. RESULTS: FEV was positively associated with intake of vitamin E in Finland, with intake of fruit in Italy, and with intake of beta-carotene in the Netherlands. In all three countries men with intakes of both fruit and vegetables above the median had a higher FEV than those with a low intake of both foods. The difference in FEV ranged from 110 to 169 ml before and from 53 to 118 ml after energy adjustment. Differences in FEV for intake of three antioxidants (vitamins C and E and beta-carotene) above versus below the median ranged from 61 to 181 ml before and from -35 to 58 ml after energy adjustment. Intake of fish was not associated with FEV. CONCLUSIONS: In three European countries a high intake of fruit and vegetables was positively associated with pulmonary function. A high intake of all three antioxidants tended to be positively associated with pulmonary function before, but not after, adjustment for energy intake. Associations of individual antioxidants with pulmonary function were not consistent across countries.
