- AIM: To investigate risk factors for the development of diabetes in middle-aged women. METHODS: A random population sample of 1351 women without prior diabetes or cardiovascular disease, aged 39-65 years, took part in a screening study in 1979-1981 with questionnaires, physical examination and blood sampling. Development of diabetes up to 1998 was identified at a second examination in 1997-1998. RESULTS: Seventy-three women (5.4%) were diagnosed with diabetes during follow-up. As expected, obesity resulted in a rising age-adjusted risk with hazards ratio 3.2 [95% confidence interval (CI) 1.3, 8.1] at body mass index (BMI) 24-27 kg/m(2), and 8.3 (3.5, 19.7), at BMI > or = 27, compared with BMI < 22 kg/m(2). S-triglycerides (TG) carried a steeply increasing age-adjusted risk with hazards ratio 4.0 (95% CI 2.1, 7.6) already at s-TG 1.0-1.4 mmol/l, 7.1 (3.6, 14.0) at s-TG 1.5-1.9 mmol/l and 9.3 (4.3, 20.2) at s-TG > or = 2.0 mmol/l compared with s-TG < 1.0 mmol/l. Increasing systolic blood pressure (SBP) to 130-144, 145-159 and > or = 160 mmHg escalated the hazards ratio of diabetes to 1.6 (0.8, 3.3), 3.6 (1.7, 7.4) and 5.6 (2.7, 11.4), respectively, compared with SBP < 130 mmHg. Also, low physical activity predicted diabetes, with hazards ratio 2.1 (1.3, 3.3) for sedentary compared with non-sedentary activity. Smoking was not associated with increased risk of diabetes. After adjustment for BMI, SBP and physical activity, increasing TG level remained a strong and significant risk factor for diabetes [hazards ratio 3.0 (1.6, 5.7), 3.7 (1.8, 7.7) and 4.5 (2.0, 10.0), P < 0.001]. CONCLUSIONS: Among middle-aged Swedish women even very slightly elevated s-TG resulted in a considerably enhanced risk of developing diabetes, which was independent of age, BMI, blood pressure and physical activity.

- AIM: To present reference values and correlations with body composition, blood variables and lifestyle factors. SUBJECTS: Two random population samples from Göteborg, Sweden, one comprising 184 men and 455 women aged 25-64 years (MONICA) and the other 860 women aged 55-82 years (BEDA) were studied. METHODS: Calcaneal ultrasound measurement (LUNAR Achilles) and bioimpedance were measured. Smoking habits, coffee consumption, physical activity, psychological stress, education and marital status, as well as blood lipids, blood pressure, and fractures were studied. RESULTS: Broadband ultrasound attenuation and stiffness were higher in men than in women (P < 0. 001), but speed of sound did not differ between sexes. Speed of sound, broadband ultrasound attenuation and stiffness decreased with age (P < 0.001). In both sexes speed of sound, broadband ultrasound attenuation and stiffness correlated positively to body size variables, and negatively with smoking in women after adjustment for age. Speed of sound, broadband ultrasound attenuation and stiffness were positively related to physical activity in both sexes, and these relationships were the only ones that remained in multivariate analyses in addition to age (negative). Osteoporotic fractures increased with age. Speed of sound, broadband ultrasound attenuation and stiffness were lower amongst women with osteoporotic fractures. CONCLUSION: Speed of sound, broadband ultrasound attenuation and stiffness decreased with age and increased with physical activity, but body weight and height were not correlated in multivariate analyses. Osteoporotic fractures increased with age and were associated with lower calcaneal ultrasound values.

- OBJECTIVES: To examine the long-term incidence of diabetes in relation to coffee consumption in Swedish women. DESIGN: Prospective longitudinal cohort study. SETTING: City of Goteborg, Sweden. SUBJECTS: A random population sample of 1361 women, aged 39-65 years, without prior diabetes or cardiovascular disease took part in a screening study in 1979-1981 with questionnaires, physical examination and blood sampling. MAIN OUTCOME MEASURES: The development of diabetes until 1999 was identified by questionnaires in a second screening and the Swedish hospital discharge register. RESULTS: Altogether, there were 74 new cases of diabetes. The risk of developing diabetes was 475 per 100 000 person-years in women who consumed two cups of coffee or less per day, 271 in women who consumed three to four cups per day, 202 with a consumption of five to six cups per day, and 267 in drinkers of seven cups or more per day. Associated hazard ratios, after adjustment for age, smoking, low physical activity, education and body mass index were 0.55 (0.32-0.95), 0.39 (0.20-0.77) and 0.48 (0.22-1.06) for daily consumption of three to four, five to six and seven cups or more, respectively, with a consumption of less than two per day as reference. Additional adjustment for serum cholesterol and triglycerides attenuated the relation between coffee and diabetes slightly, indicating a possible mediating effect on the effect of coffee by serum lipids. CONCLUSIONS: The findings of the present study support the hypothesis that coffee consumption protects from the development of diabetes in women.

- BACKGROUND AND PURPOSE: Data on the association between obesity and stroke are still limited. We examined the possible association between mid-life body mass index (BMI) and risk of stroke in the prospective Multifactor Primary Prevention Study in Goteborg, Sweden. METHODS: 7402 apparently healthy men aged 47 to 55 at baseline were followed-up over a 28-year period. Incidence of fatal and nonfatal stroke was recorded in a local stroke registry through the Swedish National Register on Cause of Death and the Swedish Hospital Discharge Registry. RESULTS: A total of 873 first strokes were recorded, including 495 ischemic, 144 hemorrhagic, and 234 unspecified strokes. Compared with men with low normal weight (BMI, 20.0 to 22.49 kg/m2), men with BMI >30.0 kg/m2 had a multiple adjusted hazard ratio of 1.93 (95% CI, 1.44 to 2.58) for total stroke, 1.78 (95% CI, 1.22 to 2.60) for ischemic stroke, and 3.91 (95% CI, 2.10 to 7.27) for unspecified stroke. There was no significant association between BMI and hemorrhagic stroke. Adjustment for potential mediators, eg, hypertension, diabetes and serum cholesterol levels, attenuated but did not eliminate the risk. CONCLUSIONS: In this prospective population-based study of men, increased BMI in mid-life was associated with an increased risk for total, ischemic, and unspecified stroke, but not with hemorrhagic stroke. The result supports the role of mid-life BMI as a risk factor for stroke later in life and suggests a differentiated effect on stroke subtypes.

- Tissue-type plasminogen activator (tPA) plays a key role in thrombus dissolution and plasma levels of tPA have been associated with cardiovascular disease. We have previously resequenced regulatory and coding regions of the human tPA gene (PLAT) and identified eight single-nucleotide polymorphisms (SNPs). In a small experimental study, four common variants were associated with invasively determined vascular tPA release rates. The aim of the present study was to investigate whether there is an association between genetic variants at this locus and plasma levels of tPA. To this end, 240 Swedish individuals without cardiovascular disease were typed for the eight SNPs and an Alu insertion polymorphism at the PLAT locus, as well as for a polymorphism in the plasminogen activator inhibitor type 1 (PAI-1) promoter (PAI-1 -675 4G>5G). Stepwise regression analysis, with established predictors of plasma tPA including plasma PAI-1 and genetic variants, showed that neither genotypes nor haplotypes were major contributors to plasma tPA. The results also showed that the level of linkage disequilibrium was high at the PLAT locus, as demonstrated by the fact that only three haplotypes had a frequency above 5%. In conclusion, in the present study neither genetic variation at the PLAT locus nor the PAI-1 -675 4G>5G polymorphism was strong predictors of plasma tPA levels, which suggests that variations in other genes contribute to the heritability of this phenotype. The results also show that three haplotypes at the PLAT locus accounted for nearly 90% of the chromosomes and that they could be defined by typing only two SNPs.

Symptoms in acute coronary syndromes: does sex make a difference?
- 2004

Ingår i: Am Heart J. - 1097-6744. ; 148:1, s. 27-33

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Coronary heart disease is a major problem in both men and women, but several studies have shown sex differences in symptoms of acute coronary syndromes (ACS). Some findings, however, have been disparate and inadequate, and thus a comprehensive overview of this literature would be of value. METHOD: Fifteen studies that identified symptoms of ACS for both women and men were examined through a review of the literature from 1989 to 2002. Terms used for the search included "myocardial infarction," "symptoms," "gender differences," and "acute coronary syndromes." RESULTS: Although chest pain was the most common symptom in both men and women, several differences were also noted. In all types of ACS, women had significantly more back and jaw pain, nausea and/or vomiting, dyspnea, indigestion, and palpitations. In a number of studies, which solely sampled patients with acute myocardial infarction, women demonstrated more back, jaw, and neck pain and nausea and/or vomiting, dyspnea, palpitations, indigestion, dizziness, fatigue, loss of appetite, and syncope. Men reported more chest pain and diaphoresis in the myocardial infarction sample. The designs and methodologies of the studies varied considerably. CONCLUSION: In addition to the typical symptom of chest pain in ACS, women experience other atypical symptoms more frequently than men. Thus, there may be sex differences in the symptoms of ACS, differences that have a bearing not only on clinical practice, but also on the interpretation of available clinical studies and the design of future investigations.

- BACKGROUND: Psychosocial factors have been reported to be independently associated with coronary heart disease. However, previous studies have been in mainly North American or European populations. The aim of the present analysis was to investigate the relation of psychosocial factors to risk of myocardial infarction in 24767 people from 52 countries. METHODS: We used a case-control design with 11119 patients with a first myocardial infarction and 13648 age-matched (up to 5 years older or younger) and sex-matched controls from 262 centres in Asia, Europe, the Middle East, Africa, Australia, and North and South America. Data for demographic factors, education, income, and cardiovascular risk factors were obtained by standardised approaches. Psychosocial stress was assessed by four simple questions about stress at work and at home, financial stress, and major life events in the past year. Additional questions assessed locus of control and presence of depression. FINDINGS: People with myocardial infarction (cases) reported higher prevalence of all four stress factors (p<0.0001). Of those cases still working, 23.0% (n=1249) experienced several periods of work stress compared with 17.9% (1324) of controls, and 10.0% (540) experienced permanent work stress during the previous year versus 5.0% (372) of controls. Odds ratios were 1.38 (99% CI 1.19-1.61) for several periods of work stress and 2.14 (1.73-2.64) for permanent stress at work, adjusted for age, sex, geographic region, and smoking. 11.6% (1288) of cases had several periods of stress at home compared with 8.6% (1179) of controls (odds ratio 1.52 [99% CI 1.34-1.72]), and 3.5% (384) of cases reported permanent stress at home versus 1.9% (253) of controls (2.12 [1.68-2.65]). General stress (work, home, or both) was associated with an odds ratio of 1.45 (99% CI 1.30-1.61) for several periods and 2.17 (1.84-2.55) for permanent stress. Severe financial stress was more typical in cases than controls (14.6% [1622] vs 12.2% [1659]; odds ratio 1.33 [99% CI 1.19-1.48]). Stressful life events in the past year were also more frequent in cases than controls (16.1% [1790] vs 13.0% [1771]; 1.48 [1.33-1.64]), as was depression (24.0% [2673] vs 17.6% [2404]; odds ratio 1.55 [1.42-1.69]). These differences were consistent across regions, in different ethnic groups, and in men and women. INTERPRETATION: Presence of psychosocial stressors is associated with increased risk of acute myocardial infarction, suggesting that approaches aimed at modifying these factors should be developed.

- Low social class is associated with higher mortality from cancer at several sites and in patients with cancer low social class is known to be associated with a poorer chance of survival. Social differences in cancer incidence are less consistent. The present study was undertaken to assess the relation between occupational class and cancer incidence, mortality and survival from cancer in a large population of 7001 men aged 51-59, free of diagnosed cancer at baseline in 1970--1972. The main outcome measures were cancer incidence and cancer mortality until 1992 according to the Swedish national cancer and cause-specific death registries. Cancer survival was analysed in a subgroup of 904 men diagnosed with cancer before 1990. There were 1329 incident cases of cancer including 620 deaths from cancer. Overall cancer incidence during follow-up did not vary significantly by occupational class, but respiratory cancers were significantly more common among men with manual occupations; p = 0.0004. This was not be explained by differences in tobacco smoking, which were minor at the start of the study and did not increase much during follow-up. Overall mortality from cancer was significantly higher among men with manual occupations. Among professionals and higher officials 336 per 100,000 observation years died from cancer, compared to 391 among intermediate officials, 509 among lower officials, 474 among skilled and 548 among non-skilled workers; p for trend = 0.0003. This difference was mainly due to mortality from respiratory cancer, with a threefold difference between manual workers and professionals; this did not change after adjustment for smoking. Among the 904 men diagnosed before 1990 with cancer at any site (except non-melanoma skin cancer) the adjusted relative risk of dying from cancer was 1.75 (95% confidence interval 1.22-2.50) in unskilled workers compared to higher officials (p for trend 0.015).

- AIMS: Low socio-economic status is a well-known risk factor for coronary heart disease (CHD), but the evidence concerning social network has been less consistent. In this prospective cohort study of men we sought to estimate the impact of social network factors on the risk of incident coronary heart disease and mortality from all causes. METHODS AND RESULTS: In a population of 741 men aged 50 at baseline 92 new cases of coronary disease were identified over a follow-up period of 15 years. Social factors included occupational class, two measures of social support-- "emotional attachment" and "social integration"-- and a measure of global mental stress. Among the men in the lowest quartile of social integration, there were 13.6 cases (per 1000 observation years), compared to 8.9 in the intermediate two quartiles and 6.0 in the highest quartile (P for trend 0.003). After adjustment for all relevant risk factors the hazard ratio (HR) for the highest, compared with the lowest, quartile was 0.45 (0.24-0.84);P for trend 0.013. Emotional attachment was also associated with significantly reduced risk. The adjusted HR for the lowest quartile was 0.58 (0.37-0.91); P=0.019. No relation between mental stress and risk of CHD, or between low occupational class and risk of CHD was found. CONCLUSION: In this prospective study of men, we found two dimensions of low social support-low social integration and low emotional attachment-to be predictive of coronary morbidity, independently of other risk factors.
