OBJECTIVE: To examine the association between serum HDL-cholesterol concentration (HDL-C) and self rated health (SRH) in several age groups of men and women. STUDY DESIGN AND SETTING: The study had a cross-sectional design and included 18,770 men and women of the Oslo Health Study aged 30; 40 and 45; 69-60; 75-76 years. RESULTS: In both sexes and all age groups, SRH (3 categories: poor, good, very good) was positively correlated with HDL-C. Logistic regression analysis on dichotomized values of SRH (i.e. poor vs. good health) in each age group of men and women showed that increasing HDL-C values were associated with increasing odds for reporting good health; the odds ratio (OR) was highest in young men, and was generally lower in women than in men. Odds ratios in the 4 age groups of men were 4.94 (2.63-9.29), 2.25 (1.63-3.09), 2.12 (1.58-2.86), 1.87 (1.37-2.54); and in women: 3.58 (2.46-5.21), 2.81 (2.23-3.53), 2.28 (1.84-2.82), 1.61 (1.31-1.99). In the whole material, 1 mmol/L increase in HDL-C increased the odds for reporting good health by 2.27 (2.06-2.50; p
BACKGROUND: Since information about the association between serum albumin and risk of stroke is limited the purpose of the present paper was to re-investigate this relationship. DESIGN: The study followed a cross-sectional design. METHODS: In the cross-sectional Norwegian Oslo Health Study the concentration of serum albumin and blood pressure was determined in a random sample of 5071 men and women, 30-75 years of age. Logistic regression was used to study the association between the serum albumin concentration and self-reported prevalence of stroke. In the sample there were 122 subjects with a history of stroke and 4949 subjects without. RESULTS: Low albumin (i.e. 47 g/l) was associated with increased prevalence of self-reported stroke (odds ratio 1.83; 95% confidence interval, 1.20-2.78; P=0.005), after adjusting for age ( or =59 years) and sex. Including smoking, blood pressure and length of education into the model did not have any major influence on the result. CONCLUSION: Low serum albumin is associated with increased prevalence of self-reported stroke.
