Aim: To investigate the development of blood pressure (BP) determinants over a period of 6 years in a birth cohort of middle-aged Swedish men. Methods: Men born 1953 and 1954 living in Helsingborg, Southern Sweden, were surveyed at 37, 40 and 43 years of age. Baseline participation rate was 68% (n = 991). S-Cholesterol, HDL-Cholesterol, systolic and diastolic blood pressure (SBP and DBP) and anthropomorphic measurements were collected and a questionnaire covering ethnicity, smoking, leisure time physical activity (LTPA) and alcohol consumption was completed. Results: At these surveys, SBP means were: 131, 132, 135 mm Hg and DBP were 83, 83 and 85 mm Hg respectively. Body mass index (BMI), waist hip ratio (WHR), S-Cholesterol and alcohol consumption consistently showed cross-sectional positive associations with SBP and DBP. One mmol/L higher S-Cholesterol at baseline predicted an increase in SBP by 1.16 mm Hg (confidence interval, CI: 0.25; 2.07) over 6 years. At age 40, there was a 4.4 mm Hg (p < 0.020) difference in SBP and a 2.64 mm Hg (p < 0.056) difference in DBP means between the low and high alcohol consumption. Corresponding differences at age 43 were SBP 5.28 mm Hg (p < 0.023) and DBP 5.4 mm Hg (p < 0.000). Men born in Sweden had a higher baseline SBP (A = 4 mm Hg, CI: 2.11; 6.35) and showed a higher 6 year increase in SBP (2.80 mm Hg CI: 0.07; 5.53) than men born abroad. Conclusions: Body composition, ethnicity and alcohol consumption are strong determinants for the development of BP. These findings have to be considered in strategies for primary prevention of hypertension in younger middle-aged men.
