- BACKGROUND: Short body height is associated with increased risk for coronary heart disease; however, mechanisms are not fully explained. In this study, associations between body height and serum cholesterol, non-high-density lipoprotein (non-HDL cholesterol) and high-density lipoprotein (HDL cholesterol) were investigated. METHODS: Prospective cohort study of middle-aged men from Helsingborg, Sweden starting 1990. Two birth-year cohorts were invited at 37, 40 and 43 years of age; participation at baseline was 991 (68%). Serum and HDL cholesterol, systolic and diastolic blood pressure, weight, height, waist and hip circumferences were measured. Non-HDL cholesterol, body mass index (BMI) and waist/ hip ratio (WHR) were calculated. The participants completed a questionnaire covering lifestyle variables. RESULTS: There were statistically significant inverse correlations between body height and serum cholesterol (-0.11) and non-HDL cholesterol (-0.12). One standard deviation, 6.7 cm, taller body height was associated with a lower serum cholesterol (-0.12 mmol/l) and a lower non-HDL cholesterol (-0.13 m mol/l; p < 0.001). These associations remained when adjusted for BMI and WHR. Men with serum cholesterol equal to or above 6.5 mmol/l were significantly shorter (mean 178.71 cm) than men with serum cholesterol below 6.5 mmol/l (mean 179.71 cm). In addition, BMI and WHR were positively associated with serum and non-HDL cholesterol and inversely associated with HDL cholesterol. The change in cholesterol levels over the six-year follow-up was significantly associated to the change in BMI and WHR. CONCLUSIONS: Body height had an independent and inverse relation to serum cholesterol and non-HDL cholesterol in middle-aged men, and the lipid pattern suggests that the underlying mechanism might be different from the traditional association between lipids and the metabolic syndrome. Although the direct clinical implication is limited, our results may help to explain the association between short height and risk of myocardial infarction.

- Aims: To investigate associations between CVD risk factors and socio-economic status (SES) in middle-age men during a period of economic changes. Methods: Crossectional surveys at age 37, 40 and 43 in a birth cohort of men in Helsingborg, Sweden. All male residents born 1953 - 4 (n=1460) were invited; participation rates were 68% (n=991) at baseline. Of these enrolled, 78% (n=770) were re-examined after three years and 71% (n=702) again after six years follow-up. Main outcome measures were body mass index (BMI), S-cholesterol, HDL-cholesterol, systolic and diastolic blood pressure (SBP, DBP), smoking and leisure time physical activity (LTPA), education, employment, ethnicity. Results: Baseline unemployment rate was low, n=23 (2.4%), but three and six years later it had increased to 61 (8.2%) and 51 (7.5%) respectively. At baseline, BMI and S-cholesterol were significantly higher in unemployed than in employed men (ΔBMI 1.6 kg/m2, CI: 0.2; 2.9, Δ S-cholesterol 0.6 mmol/L, CI: 0.1; 1.0), and in men with short versus long education (Δ BMI 0.9 kg/m2, CI: 0.4; 1.4, Δ S-cholesterol 0.2 mmol/L, CI: 0.03: 0.4), independent of other SES factors. Over the study period crossectional associations with employment status disappeared for BMI, but remained between short education and BMI. Short education was also associated with a significant increase in BMI (Δ=0.4 kg/m2, CI: 0.1; 0.7) during 6-year follow-up. Conclusions: This study shows that associations between unemployment and CVD risk factors were lost when unemployment rates increased. When the attributable risk of unemployment associated with CVD risk factors is estimated, it is vital to consider the general unemployment rates in society.

- OBJECTIVES: To explore the development of hypertension (HT) in a cohort of young middle-aged men. DESIGN: Prospective birth-cohort study of men surveyed over 6 years. SETTING: Helsingborg County Hospital, Sweden, 1990-97. SUBJECTS: A total of 628 men born in 1953-54, all surveyed at 37, 40 and 43 years of age. MAIN OUTCOME MEASURES: Systolic blood pressure (SBP), diastolic blood pressure (DBP), S-cholesterol, body mass index (BMI), alcohol consumption, ethnicity. HT was defined as SBP > or = 140 mmHg and/or DBP > or = 90 mmHg, or ongoing treatment. Using SBP < 130 mmHg and DBP < 85 mmHg as reference, the odds of conversion to HT in men with high normal blood pressure (BP) (SBP 130-139 mmHg and DBP 85-89 mmHg) was investigated. RESULTS: At age 37, 243 men (39%) had reference BP, 167 (26%) had high normal BP and 218 (35%) were hypertensive. Corresponding numbers at age 40 were 265 (42%), 166 (27%) and 197 (31%); and at age 43, 180 (29%), 142 (22%) and 306 (49%), respectively. High normal BP at baseline was associated with the development of HT both at age 40 (odds ratio (OR)=2.45 confidence interval (CI): 1.42-4.22) and at age 43 (OR=2.46, CI: 1.59-3.80), independent of other cardiovascular disease risk factors and ethnicity. The progression to HT was predicted also by S-cholesterol, alcohol consumption, BMI and weight gain. CONCLUSIONS: Over a short-term period, a substantial proportion of young middle-aged men with high normal BP develop HT with overweight and alcohol consumption as important determinants. These findings have implications for the prevention, screening and medical care of HT in this target population.

- Serum total sialic acid (S-TSA) is a recently identified risk marker for atherosclerosis and cardiovascular mortality. The purpose of this study was to evaluate the influence of three sialic acid rich glycoproteins (orosomucoid, haptoglobin, and alpha1-antitrypsin) on the relationship between S-TSA and carotid atherosclerosis. The mean S-TSA was 0.045 g/l higher among cases than controls (P<0.001) in 310 45-64 year-old male and female pairs of carotid atherosclerosis cases and disease-free controls from the Atherosclerosis Risk in Communities (ARIC) Study. Also mean serum levels of the glycoproteins were significantly higher in cases compared to controls. In a conditional multiple logistic regression model with the glycoproteins as independent variables, orosomucoid was correlated most strongly with case control status. However, when incorporated into the mathematical model, S-TSA not only contributed additional information as to the risk of atherosclerosis; none of the three glycoproteins contributed further once S-TSA had been accounted for. Thus, some other source of serum sialic acid or variations in the degree of sialylation of glycoproteins may be essential for understanding the relation between S-TSA and atherosclerosis.

- BACKGROUND: Previous studies have shown that the serum level of sialic acid is associated positively with mortality from coronary disease and stroke. In this study its relation with carotid atherosclerosis was evaluated. METHODS: From the Atherosclerosis Risk in Communities (ARIC) Study, 323 cases with carotid intima-media wall thickness above the 90th percentile (measured with B-mode ultrasound) were matched 1:1 with controls without atherosclerosis. Serum sialic acid, plasma LDL and HDL cholesterol, serum insulin concentrations, blood pressure, antihypertensive medication use, and smoking status were used to assess the independent contribution of the sialic acid level to carotid atherosclerosis. RESULTS: The mean (SD) serum sialic acid concentration was 75.0 (9.7) mg/dl in cases and 70.7 (8.9) mg/dl in controls (P = 0.0001). In a conditional logistic model with adjustment for age, LDL-cholesterol, HDL-cholesterol, serum insulin, smoking and hypertension, the odds ratio associated with sialic acid above the 75th percentile (> or = 78.3 mg/dl) versus below was 1.65 with a 95% confidence interval of 1.01-2.70. CONCLUSION: The sialic acid level is correlated with the presence of carotid atherosclerosis, independently of major cardiovascular disease risk factors. The biological mechanism behind this association is not resolved.
