- OBJECTIVES: To validate the use of an activity diary and predicted BMR for assessment of daily total energy expenditure (TEE) and physical activity level (PAL = TEE/BMR) in adolescents.DESIGN: TEE and PAL estimated from activity diary records kept for seven days and BMR predicted from age, gender and body weight were compared with the results of doubly labelled water (DLW) measurements and indirect calorimetry performed during the same time period.SETTING: The Unit of paediatric Physiology of the Department of Clinical Physiology, University Hospital, Uppsala, Sweden.SUBJECTS: Fifty randomly selected 15 y old adolescents (25 boys and 25 girls).RESULTS: The mean difference between TEE estimated in all adolescents by the activity diary and by DLW methods was 1.2%. The limits of agreement (mean difference 2 s.d.) were -3.47 and 3.77 MD/d, equivalent to a coefficient of variation of 15%. The mean difference between PAL assessed by activity diary records and by DLW measurements was 0.001, and the limits of agreement between the two methods were 0.54.CONCLUSIONS: The results imply that the activity diary method provides a close estimate of TEE and PAL in population groups.

- OBJECTIVES: To assess the average daily levels of physical activity, energy expenditure and the time and energy spent a different activities in two cohorts of Swedish adolescents.DESIGN: Total energy expenditure (TEE) and physical activity level (PAL = TEE/basal metabolic rate (BMR)) were estimated in 374 randomly selected healthy adolescents living with two different regions of Sweden on the basis of a seven-day activity diary (AD) and predicted BMR. A validation of the estimates from the AD with the doubly labelled water (DLW) method in a randomly selected subsample of 50 of these subjects is presented elsewhere.SETTING: The Unit of Paediatric of the Department of Clinical Physiology, University Hospital, Uppsala and the Department of Paediatrics, Northern Alvsborg Hospital, Trollhättan, Sweden.RESULTS: No significant differences in TEE and PAL were found between the adolescents of the two regions. High levels of TEE (14.2 and 10.9 MJ/d in boys and girls, respectively) and PAL (1.95 and 1.80) were observed. There was a close association between the PAL and the adolescents and their reported time spent sitting. Those with the lowest PAL values spent 3-6 h longer each day sitting compared to those with the highest PAL values. The results also indicate that everyday activities such as walking and bicycling have a crucial impact on the PAL values.CONCLUSIONS: In the 15 y old adolescents of the two studied regions of Sweden, high and concordant levels of energy expenditure and physical activity were found.

- Objective: To investigate the distribution across the different stages of change for each of the 15 participating European countries, and the effect of socio-demographic variables such as sex and education on this distribution. Also to assess the relationships between stages of change and influences of food choice, and other variables. Design: A cross-sectional study in which quota-controlled, nationally-representative samples of approximately 1000 adults from each country completed a face-to-face interview-assisted questionnaire. Setting: The survey was conducted between October 1995 and February 1996 in the 15 member states of the European Union. Subjects: 14,331 subjects (aged 15 y upwards) completed the questionnaire. Data were weighted by population size for each country and by sex, age and regional distribution within each member state. Subjects were divided into five different categories according to their attitudes towards 'changing their eating habits in order to eat healthier': (1) Precontemplation; do not consider any changes, (2) Contemplation; consider changes, (3) Decision; make plans to change, (4) Action; carry out the changes, and (5) Maintenance; maintained changes for more than six months. Results: 52% of the subjects were in the precontemplation stage, whereas 31% of the subjects were in the maintenance stage. Two, one, and seven percent of subjects were in the contemplation, decision and action stage, respectively. In the Mediterranean countries, and in Germany, there were more people (55-64%) in the precontemplation stage, whereas in the Scandinavian countries there were less people in precontemplation stage (20-38%). The opposite was true for the maintenance stage, whereas women and people with a higher education level tended to be more in the maintenance stage. With respect to influences on food choice, subjects in precontemplation stage found that taste was more important, whereas people in maintenance stage found that health was more important. Conclusions: The stages of change model makes a useful distinction between people with different attitudes towards nutrition and health. Nutrition education can benefit from this distinction.

- Background: Prevalence of peptic ulcer disease has been associated to diet. Some dietary factors seem to have bactericidal effect which may modify the risk of peptic ulcer disease. The objective was to analyze associations between dietary habits and peptic ulcers. Design: A cross sectional population study. Subjects: One thousand, one hundred and thirty-five subjects out of 11,700 randomly invited men and women, aged 46-67 y, participating in a diet and disease study during 1991-1993. The study population comprised of 764 cases with reported peptic ulcer, 142 with dyspeptic symptoms and 229 randomly selected controls. Methods: X-ray examinations and endoscopies were reviewed and 332 out of 764 peptic ulcer cases were verified. Mean daily intake of foods and nutrients were assessed with a combined 7 d menu book and a quantitative food frequency questionnaire, including dietary supplements. Results: Subjects with verified ulcer had lower intake of fermented milk products and vegetables and higher intake of milk, meal and bread than controls. Intake of total fat, saturated and monounsaturated fatty acids and linolenic acid were higher in the ulcer group. Higher intake of fermented milk products, by quintiles showed a decreased ulcer risk; odds ratio 0.82 (0.71-0.95), adjusted for covariates below. Higher intake of milk, by quintiles, was associated with an increased risk of ulcer; odds ratio 1.17 (1.03-1.32). Smoking, foreign ethnicity and being unmarried or divorced were covariates associated to ulcer. Conclusion: This study indicates the multifactorial etiology of peptic ulcer including dietary factors. High intake of fermented milk products was associated with decreased risk for ulcer, whereas increased risk was noted for high milk intake.

Tidskriftsartikel (refereegranskat)abstract
- Objective: Evaluate the impotrtance of incomplete gelatinization, food structure and presence of viscous dietary fibre for the postprandial glycaemic and insulinaemic responses to oat and wheat products. Design: Three common breakfast meals were tested, "raw" rolled oats (muesli), boiled rolled oats (oat porridge) and white wheat bread. Boiled intact oat and wheat kernels (kernel porridges) were also included. For comparison, glycemic indices (GIs) were calculated both from analysis of capillary and venous blood samples. Subjects: Nine healthy male volunteers between 65 and 70 years of age participated in the study. Results: The rolled oats and oat porridge elicited high metabolic responses. No differences in glycaemic and insulinaemic indices (IIs) were seen between these products and white bread. In contrast, the kernel porridges produced low glucose and insulin responses. No differences were obtained in GI values whether based on capillary or venous blood. However, with some products capillary blood allowed smaller differences to be detected. Conclusions: Neither incompleate gelatinization in rolled oats nor naturally occuring viscous dietary fibre in oats affect postprandial glycaemia, whereas enclosure if intact kernels significantly blunt metabolic responses.

- OBJECTIVE: To describe the food habits of Swedish adolescents 14-15 y of age. To analyse the connection between food habits and socioeconomic circumstances and background factors.DESIGN: Cross-sectional survey using a Food Frequency Questionnaire including questions on meal patterns.SETTING: The city of Göteborg and the County of Alvsborg, Sweden 1996.SUBJECTS: Pupils in the 8th grade in all schools in the city of Göteborg and the County of Alvsborg were in February 1996 invited to participate. The study comprised 7605 pupils. The drop-out rate was 14.4% (n = 1280).RESULTS: The adolescents had an infrequent consumption of vegetables and fruits and they had a daily consumption of sweets. Cereals, dairy products and snacks: buns, wafers, soft drinks, ice cream and potato crisps were consumed more than once a day. Thirty percent of the girls and 20% of the boys did not eat breakfast every day. The free school lunch was eaten daily by 50% of the boys and 30% of the girls, the remainder ate some type of snack. A negative correlation was found between smoking and the frequency of vegetable consumption. Pupils from areas with high socioeconomic status more often ate breakfast and lunch and the boys more often ate dinner compared to adolescents from areas with low socioeconomic status.CONCLUSIONS: An irregular meal pattern as well as snack consumption and smoking were common, especially among girls in areas with low socioeconomic status.

- OBJECTIVE: The purpose of this baseline survey was to obtain comparable data on perceived influences on food choice from EU member countries as the starting point for EU healthy eating promotion campaigns and programmes.DESIGN: A cross-sectional study in which quota-controlled, nationally-representative samples of approximately 1000 adults from each country completed a face-to-face interview-assisted questionnaire.SETTING: The survey was conducted between October 1995 and February 1996 in the 15 member states of the European Union.SUBJECTS: 14331 subjects (aged 15 y upwards) completed the questionnaire. Data were weighted by population size for each country and by sex, age and regional distribution within each member state.RESULTS: The five most important factors influencing consumers food choice were 'quality or freshness' (74%), 'price' (43%), 'taste' (38%), 'trying to eat healthy' (32%) and 'family preferences' (29%). Subjects in different categories (age, sex, education and employment status) selected different factors as having major influence on their food choice. Demographic factors seemed to have greater effects on perceived influences than culture (country): 'quality/freshness', 'price', 'trying to eat healthy', 'family preferences' seemed to be most important in women, 'taste' and 'habit' in males. Females and older and more educated subjects were more likely than other subjects to select 'trying to eat healthy' as having a major influence. 'Price' seemed most important in unemployed and retired subjects.

- OBJECTIVE: To test the short and long-term effectiveness of a four week residential program for primary health care patients to control obesity and related risk factors for cardio-vascular disease (CVD), especially blood pressure (BP).DESIGN: Prospective clinical study, with follow up after 1 and 5 y.SETTING: Vindeln Patient Education Centre, Vindeln, and Department of Social Medicine, University of Umea, Sweden.SUBJECTS: Approximately 2500 individuals, with two or more of the traditional risk factors for CVD, participated in the program. This report describes a subsample of 100 consecutive patients, 52+/-9 y, 53 men, with obesity and/or high BP. Intervention: Four week residential program with lectures and group discussions as well as practical sessions in smaller groups (meal preparations, physical exercise, etc). The patients were followed-up medically in their home area.OUTCOME MEASURES: Weight and blood pressure.RESULTS: Dramatic reductions of weight and, especially, of blood pressure (BP) occurred during the residential weeks, and the reductions were pronounced also after 1 y. After 5 y, the total mean weight among men with initial BMI > or = 30 kg/m2 was still 5 kg lower, and diastolic and systolic BP among those with hypertension was 15 and 20 mm Hg lower, respectively, than before the program.CONCLUSIONS: The full-time participation in the residential program and the enrollment and commitment of the patients may explain the clinical outcome. A level of predisposition greater than that required of most weight- and BP-control programs was confirmed and a great preventive or therapeutic potential was indicated. The study illustrates an effective application of the Precede-Proceed model of health promotion planning.
