- Department of Internal Medicine, Sahlgrenska University Hospital, Göteborg, Sweden. INTRODUCTION: The food-marking symbol the 'Green Keyhole' has been in use since 1989 in Sweden, to make it easier for consumers to select low-fat and high-fibre alternatives. OBJECTIVE: To describe knowledge of the Green Keyhole symbol in a general population of both sexes and the association between knowledge and intake of Green Keyhole labelled foods. DESIGN: A cross-sectional study within the GOT-MONICA project 1995/96. Subjects: 732 males and 859 females, aged 25-64 y. METHODS: Reported intakes of Green Keyhole labelled low-fat and fibre-enriched foods from a food frequency questionnaire, in relation to knowledge of the Green Keyhole symbol. RESULTS: 53% and 76% of the males and females, respectively, understood the meaning of the symbol. Subjects with knowledge were significantly younger (P<0.0001) and (among women) thinner (P=0.0105), than those without knowledge. Intakes of Green Keyhole labelled low-fat foods were significantly higher in males (P=0.0443) and females (P<0.0001) with knowledge of the symbol than without. An interaction between education and knowledge of the Green Keyhole symbol was found for intake of low-fat marked foods (P=0.0088). CONCLUSIONS: Both males and females with knowledge of the symbol seem to have adopted its low-fat message. However, in certain sub-groups, particularly the less educated, the message of the symbol appears to have no association with dietary practices. PMID: 10556983 [PubMed - indexed for MEDLINE]

- Consecutive patients (n=964) undergoing coronary angiography were studied and compared with a random population sample regarding serum lipids and lipoproteins with focus on lipoprotein(a) (Lp[a]) levels and apo(a) isoforms. The patients were also followed for 5 years after the angiography, and the prognostic value of serum lipoproteins were analyzed. The patients were divided in two groups: Group 1 (n=814) consisted of patients with angina pectoris and at least one coronary artery with 50% stenosis and group 2 (n=150) patients with none of the coronary arteries significantly obstructed ( < 50%). As controls a random population sample was selected (n=197). Blood samples were collected before coronary angiography for determination of serum lipids, Lp(a) and isoforms of apo(a). When group 1 and group 2 patients were compared, group 1 was found to have higher serum cholesterol, triglycerides, apoB and Lp(a) as well as lower HDL and apoAI. When group 1 was compared with the random sample, after correction for age and sex, similar differences were observed, except that the difference in Lp(a) was not significant. The high Lp(a) levels among patients was found to be primarily due to the female patients, where the difference compared to both group 2 and controls was highly significant (P=0.007 and P=0.001, respectively). There was a significant difference in the apo(a) isoform distribution between group 1 patients and control subjects (P=0.0003), with a higher frequency of low molecular weight isoforms among patients. This was also significant for the male subgroup (P=0.001). Lp(a), LDL, total cholesterol, triglycerides. apoB, HDL and apoAI were significantly related to the number of major coronary arteries with > 50% stenosis. Mortality during follow-up was,in a univariate analysis, significantly correlated to several factors related to the degree of heart disease and to LDL (P=0.02) and apoB (P < 0.01). Increased mortality was, however, related to low levels of apoB and LDL. For cardiac mortality no significant correlation to lipoprotein variables were found. In conclusion established lipoprotein risk factors were more frequent among patient with angina pectoris and verified coronary stenosis. Furthermore high Lp(a) levels and a high frequency of low molecular weight isoforms of apo(a) were found in coronary patients. Higher Lp(a) levels were observed both for female and male patients, the differences were, however, significant only for the female patients. None of the lipoprotein variables could predict coronary death during the follow-up period.

Behavioural characteristics in patients with myocardial infarction: a case-control study
- 1995

Ingår i: Journal of Cardiovascular Risk. - 1350-6277. ; 2:3, s. 247-254

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Over the past 10-20 years, evidence has accumulated suggesting that it is not just biological risk factors that are important for the development of coronary heart disease. The present study is one of a series of case-control studies in which a wide range of psychosocial factors have been analysed in the same population to obtain information on their relationship with myocardial infarction, as well as of the interaction between psychosocial and biomedical variables. METHODS: The relationship between behavioural factors and non-fatal myocardial infarction was studied by comparing consecutively admitted male (n = 288) and female (n = 55) patients with a population sample of 283 men and 129 women. All participants were under 65 years of age. The behavioural variables (type-A behaviour, health locus of control, sleep problems and alcohol consumption) were investigated by means of a self-administered questionnaire. RESULTS: No significant differences emerged between patients with myocardial infarction and controls in terms of their type-A behaviour pattern. After controlling for traditional risk factors (smoking, hypertension, serum cholesterol level and diabetes), men with myocardial infarction reported a significantly stronger external health locus of control (i.e. a weak belief in their capacity to control their health) compared with their controls, as well as more problems with sleep and a lower alcohol consumption; women with myocardial infarction reported significantly more problems with sleep than their controls. CONCLUSION: The importance of health locus of control, sleep problems and alcohol consumption is amplified by the fact that they are related to myocardial infarction independently of conventional biomedical risk factors. These behavioural factors should be studied further in prospective investigations. PMID: 7584801 [PubMed - indexed for MEDLINE]

- The relationship between psychosocial factors and nonfatal myocardial infarction (MI) was studied by comparing, controlling for traditional risk factors, consecutive male (n=55) patients, who had had a first MI, with a population sample of 283 men and 129 women. All were <65 years of age. The psychosocial factors were investigated by means of a self-administered questionnaire. Men with MI significantly more often did shift work, reported mental strain at work, reported dissatisfaction with their financial situation, and had experienced more negative life events during the last year, compared to controls. Women with MI more often reported mental strain at work and dissatisfaction with their financial situation compared with controls. After controlling for traditional risk factors (smoking, hypertension, serum cholesterol, and diabetes), all factors were still significantly related to MI among men. Among women, only mental strain at work remained significant. However, there were no differences between MI patients and controls in educational level, overtime or extra work, marital status, or other family circumstances. In multivariate analyses including traditional risk factors and all significant psychosocial factors, mental strain at work emerged as an independent risk factor in both sexes, whereas negative life events during the last year was an independent risk factor in men only.

- BACKGROUND: For more than 10 years there has been increasing evidence that not only biological risk factors are important for the development of coronary heart disease. The present study is one of a series of case-control studies in which a wide range of psychosocial factors in the same population have been analysed to obtain information on their relationship with myocardial infarction, and of the interaction between psychosocial and biomedical variables. METHODS: The association between social relationships and nonfatal myocardial infarction was studied by comparing consecutively admitted male (n = 288) and female (n = 55) patients with myocardial infarction with a population sample of 283 men and 129 women. All participants were under 65 years of age. The social relationships were investigated by means of a self-administered questionnaire. RESULTS: Men with myocardial infarction reported significantly lower perceived emotional support compared with their controls, as well as less social activity. Women with myocardial infarction reported significantly less social activity than their controls. There were no significant differences between cases and controls in social integration (number and frequency of social relationships and contacts). Neither did dissatisfaction with social relationships differ significantly between patients with myocardial infarction and controls. After controlling for traditional risk factors (smoking, hypertension, serum cholesterol level, diabetes) perceived emotional support remained significantly related to myocardial infarction in men, and so did the amount of social activity in both men and women. CONCLUSION: The importance of perceived emotional support and lack of social activity is amplified by the fact that they are related to myocardial infarction independently of conventional biomedical risk factors. These social factors should be studied further in prospective investigations. PMID: 8836861 [PubMed - indexed for MEDLINE]
