- The objective of this study was to describe the association between meal pattern and obesity. The study is based on data from the INTERGENE research programme, and the study population consists of randomly selected women and men, aged 25-74, living in the V?stra G?taland Region in Sweden. A total of 3610 were examined. Participants with measured BMI>/=30 were compared with others (BMI<30) with respect to questionnaire data on habitual meal patterns and intake of energy estimated from food frequencies and standard portions. Odds ratios (OR) with 95% confidence intervals were adjusted for age, sex, smoking and physical activity in logistic regression models. Being obese was significantly associated with omitting breakfast, OR 1.41 (1.05-1.90), omitting lunch OR 1.31 (1.04-1.66) and eating at night OR 1.62 (1.10-2.39). Obesity was also related to significantly larger self-reported portion sizes of main meals. No statistically significant relationship with intake of total energy was revealed. Thus, the results indicate that examination of meal patterns and portion sizes might tell us more about obesogenic food patterns than traditional nutrient analyses of food frequencies. Being obese was associated with a meal pattern shifted to later in the day and significantly larger self-reported portions of main meals.

- BACKGROUND: Analyzing the impact of the intake of many foods simultaneously provides additional knowledge about analyses of nutrients and might make it easier to implement recommendations for the public. OBJECTIVE: The objective was to examine food patterns in a Swedish population and determine how they are related to metabolic risk factors for cardiovascular disease. DESIGN: The study is based on data from the INTERGENE population study of women and men aged 25-74 y in western Sweden. Dietary patterns were identified with cluster analysis of 93 food frequencies reported by 3452 participants. Associations with features of the metabolic syndrome, including blood lipids, blood pressure, and anthropometric measures, were analyzed. RESULTS: Five distinct food patterns were identified, of which one was interpreted as a "healthy" reference pattern. This healthy cluster was distinguished by more frequent consumption of high-fiber and low-fat foods and lower consumption of products rich in fat and sugar. The 4 other clusters differed significantly from the reference cluster with respect to prevalence of cardiovascular disease risk factors and the metabolic syndrome. For example, body mass index and waist-to-hip ratio were significantly higher in a cluster characterized by high consumption of energy-dense drinks and white bread and low consumption of fruit and vegetables (P < 0.0001 and P = 0.004, respectively). CONCLUSIONS: It is possible to distinguish food patterns that are related to obesity and obesity-related cardiovascular disease risk factors in contrast with a more healthy pattern conforming with current dietary guidelines. Thus, the results indicate no reason for questioning the current recommendations.

- BACKGROUND: Favourable trends in cardiovascular disease have been observed in Sweden. The aim of this study was to study secular trends in a variety of cardiovascular risk factors. METHODS: Total-, low-density (LDL) and high-density lipoprotein (HDL) serum cholesterol; serum triglycerides; systolic and diastolic blood pressure; self-reported smoking and alcohol consumption were studied in repeated cross-sectional surveys. Data from four population-based samples in Goteborg, Sweden were used-WHO MONICA project 1985, 1990 and 1995, and INTERGENE 2002. A total of 2931 females and 2691 males aged 25-64 consisting of 1021-1624 randomly selected subjects at each survey period participated. RESULTS: Serum cholesterol levels showed downward trends but the decline in both total- and LDL-cholesterol seems to be levelling off from 1995 and onwards. No significant changes were observed in serum triglyceride, HDL-serum cholesterol or blood pressure levels. The majority of the participants had higher total- and LDL-serum cholesterol levels than currently recommended. Antihypertensive medical treatment increased in women and the oldest men. The prevalence of smoking decreased from 39 to 25% in women and 35 to 20% in men respectively from 1985-2002. In contrast, the prevalence of subjects consuming strong beer and wine, respectively, at least once a week almost doubled from 1990-2002. CONCLUSIONS: Cardiovascular risk factor patterns change continuously and need to be monitored. The favourable trends in LDL-serum cholesterol and smoking in the Goteborg surveys were paralleled by less favourable trends in being overweight and alcohol consumption.

- OBJECTIVE: To study secular trends in overweight and selected correlates in men and women in Göteborg, Sweden. DESIGN: Cross-sequential population-based surveys. SUBJECTS: A total of 2931 female and 2691 male subjects aged 25-64 y participated in WHO MONICA surveys (1985, 1990, 1995) and the INTERGENE study (2002). MEASUREMENTS: Body mass index (BMI), waist-to-hip ratio (WHR), prevalence of overweight (BMI> or =25 kg/m(2)), and obesity (BMI> or =30 kg/m(2)). RESULTS: Mean body weight increased by 3.3 kg for women and 5 kg for men, with a significant upward trend for BMI in men but not women over the 17-y observation period. The prevalence of overweight and obesity increased significantly in both sexes over the period. The largest increase was observed in men, and in women aged 25-34 y. In 2002, the prevalence of overweight was 38% in women and 58% in men, and the prevalence of obesity was 11% in women and 15% in men. No significant secular trends were observed for WHR, but there was an upward trend in prevalence of WHR>0.85 in women. A decreased prevalence of smoking in both sexes was observed together with an increase in reported leisure time physical activity. No significant secular trends were observed in rates of self-reported diabetes, although the risk of diabetes attributable to obesity was 24%. CONCLUSION: The results indicate that 25-64-y-olds in the recent survey were more overweight and obese than earlier studied MONICA participants. The increase in BMI was more pronounced in men while abdominal obesity increased principally in women. Although obesity and overweight are clearly important risk factors for type 2 diabetes, the number of diabetics remains low and any secular increase is not yet apparent.

- BACKGROUND: Numerous studies of the relationship between the TaqIA DRD2 A1 allele and alcohol-dependence have been performed and many of these have shown an association whereas others have not (Noble, 2003). This has consequently generated some controversy as to whether such an association actually exists (Noble, 2003). In the two recent meta-analyses by Noble (2003) and Young et al. (2004) some very important methodological issues have been discussed, which need to be addressed in forthcoming studies. Thus, the sample size is of great importance. In case-control studies it has been estimated that to detect the role of genes with small effect size of approximately 2, which is in the range of the DRD2 A1 allele-alcoholism relationship, case-control sets of 300-400 subjects are necessary (Noble, 2003). METHODS: In the present study, we have consequently recruited a large number of subjects, 375 alcohol-dependent individuals, who were treated as inpatients for alcohol withdrawal symptoms and out of these 357 could be evaluated. As controls, 578 individuals screened and 254 individuals unscreened for alcohol consumption were used. Thus, the total number of subjects was 1217. RESULTS: In the present study, in which the TaqI A1/A2 DRD2 polymorphism was in Hardy-Weinberg equilibrium in the patient group and the two control groups, we found that the TaqI DRD2 A1/A2 genotype frequency differed significantly between the alcohol-dependent group and both the total and screened control groups. Furthermore, the TaqI DRD2 A1 allele frequency was significantly overrepresented in the alcohol-dependent subjects as compared with both the total and screened control groups. The odds ratio for alcohol-dependency being associated with the A1 allele was 1.34. CONCLUSIONS: Consequently, the findings in this study lend further support to the notion of an association between the DRD2 A1 allele and alcohol-dependence, although the effect size of the DRD2 A1 allele is small.

- The role of dairy fat in the aetiology of myocardial infarction (MI) is controversial. The aim of this study was to evaluate the association between intake of dairy fat and dairy products, and risk of a first acute MI. A total of 111 MI patients with a first acute MI and 107 population controls (men and women, age 45-75 years) were studied. Diet was assessed using a 180-item food frequency questionnaire. The MI cases had higher intake of total fat, but lower intake of saturated fat and dairy fat than the control persons. No effect of dairy fat or saturated fat on the odds ratio for MI was observed, however. A significant inverse trend in odds of MI for intake of cheese was observed, but the trend was no longer significant after adjustment for smoking. The results suggest that intake of fat from dairy products may not be associated with increased risk of having a first MI. The healthy control persons had a diet that differed from the diet of the MI patients in many aspects, and dairy products were a part of this diet. This may have protected them from having a first MI.

- OBJECTIVE: To study the association between content of fatty acids from milk fat (14:0, 15:0 and 17:0) in adipose tissue and risk of a first myocardial infarction (MI). DESIGN AND SUBJECTS: A case-control study with 99 patients and 98 population controls both men and postmenopausal women, age 45-75 year. Adipose tissue fatty acids were determined by gas-liquid chromatography. RESULTS: The content of 14:0, 14:1, 15:0, 17:0 and 17:1 were all significantly higher in adipose tissue of controls than of the patients. Age and sex adjusted odds ratios (OR) for MI were significantly reduced with increasing quartiles of 14:0, 14:1, 15:0 and 17:1 in adipose tissue, but except for 15:0 (OR = 0.36, 95% CI 0.13-0.99), the trend was no longer significant after further adjustment for waist-to-hip ratio, smoking and family history for coronary heart disease. Correlations between 14:0 and 15:0 in adipose tissue, and waist-to-hip ratio were significantly negative (r = -0.22 for both, P < 0.01). CONCLUSION: Our study suggests that intake of dairy fat or some other component of dairy products, as reflected by C15:0 as marker in adipose tissue, may protect persons at increased risk from having a first MI, and that the causal effects may rely on other factors than serum cholesterol.

- OBJECTIVE: To test a simplified blood pressure device called Rastreometro that could be used by the Health Agents. METHODS: The Rastreometro has been developed from an ordinary aneroid sphygmomanometer, in which the numeric display is covered by an adhesive with a red zone, indicating pressures equal or above 140 mmHg and a yellow zone indicating pressures below 140 mmHg. The onset of oscillations of the aneroid needle is taken as an indication of the systolic pressure value. The measurements made by the Rastreometro were compared with those made by the auscultatory method, and were carried out in 268 patients, by two operators. The influence on the results of confounding variables such as age, gender, BMI, arm length, upper arm circumference, skin colour and antihypertensive treatment were taken into consideration, as well as intra and interobserver variation. RESULTS: In the whole group, sensitivity was 95.1%, specificity was 63.1%, positive predictive value was 62.4% and negative predictive value was 95.3%. Hypertensive treatment significantly affected specificity, 32.7% as compared to 77.8% for the non-treated group. Both operators improved their results over time. CONCLUSION: This study suggests that the Rastreometro technique, as a screener for hypertension, has good sensitivity. Concerning specificity, it is acceptable, provided the patient is not on regular antihypertensive treatment. In this latter situation, it can be improved by a proper standardization of the method to read the systolic pressure by needle oscillations. Furthermore, the use of this technique requires well trained operators.
