The aim of this study was to investigate the association between leukocyte subtype counts and hyper-LDL cholesterolemia, hypertriglyceridemia, and hypo-HDL cholesterolemia. Logistic regressions using hyper-LDL cholesterolemia, hypertriglyceridemia, and hypo-HDL cholesterolemia as a dependent variable and total leukocyte, basophil, eosinophil, neutrophil, lymphocyte, and monocyte counts as an independent variable were calculated adjusting for age, body mass index (BMI), high-sensitivity C-reactive protein (hs-CRP), smoking, drinking, and physical activity in apparently healthy Japanese men (1,803) and women (1,150). The odds ratio (OR) of hyper-LDL cholesterolemia for total leukocyte, eosinophil, and lymphocyte counts, the OR of hypertriglyceridemia for total leukocyte, eosinophil, neutrophil, and lymphocyte counts, and the OR of hypo-HDL cholesterolemia for total leukocyte, neutrophil, and lymphocyte counts were significant in men, and the OR of hyper-LDL cholesterolemia, for lymphocyte count, and the OR of hypo-HDL cholesterolemia for eosinophil count were significant in women. Lymphocyte count was significantly associated with hyper-LDL cholesterolemia independently of hs-CRP in apparently healthy Japanese. [ABSTRACT FROM AUTHOR]

Bilirubin is a potent antioxidant, and serum total bilirubin (TB) is reported to be negatively associated with cardiovascular disease (CVD). There has been no report on the association between TB and CVD prevalence in Japanese. The aim of the study is to examine the association between TB and CVD prevalence in a Japanese health screening population. Prevalence of CVD was studied in 3,375 Japanese men and 2,069 Japanese women. Odds ratios (ORs) of each higher quintile of TB using the lowest quintile as the reference in men and of each higher tertile of TB using the lowest tertile as the reference in women were calculated for coronary heart disease (CHD) and stroke adjusting for age, liver function tests, smoking, physical activity, and alcohol consumption. The ORs [95% confidence intervals (CIs)] for CHD and stroke of the 2nd, 3rd, 4th, and 5th quintiles of TB were 0.63 (0.37-1.07) and 0.49 (0.24-1.00), 0.45 (0.22-0.90) and 0.65 (0.28-1.51), 0.69 (0.39-1.20) and 0.37 (0.15-0.87), and 0.61 (0.34-1.09) and 0.40 (0.18-0.92), respectively in men. The ORs (95% CIs) for CHD and stroke of the 2nd and 3rd tertiles of TB were 0.63 (0.37-1.07) and 0.49 (0.24-1.00), and 0.61 (0.34-1.09) and 0.40 (0.18-0.92), respectively in women. Low TB was associated with the higher prevalence of CHD and stroke in men and with the higher prevalence of stroke in women among a Japanese health screening population. [ABSTRACT FROM AUTHOR]

Abstract: Aims: The aim of the present study was to examine the cross-sectional relationship between vital capacity and diabetes, metabolic syndrome (MS), and high-sensitivity C-reactive protein (hs-CRP) among Japanese men. Methods: Medical check-up data of 1353 men were examined. Spearman''s correlation coefficients between respiratory function and MS-related risk factors were calculated excluding subjects with hypoglycemic medication. The prevalence of diabetes and MS were compared between subjects with the lowest and the highest quartiles of % vital capacity (%VC). Area under receiver operating characteristic curve (AUC) were calculated for risk factors excluding fasting glucose. Logistic regression using diabetes as a dependent variable and %VC and MS-related risk factors excluding fasting glucose as independent variables was performed. Results: %VC was significantly correlated with some components of MS and hs-CRP. The prevalence of diabetes, MS, and MS components other than blood pressure were significantly lower in the highest quartile than in the lowest quartile of %VC. AUC of -%VC was highest among MS-related risk factors excluding fasting glucose though statistically not significant. %VC was an independent marker of diabetes in the multivariable logistic regression analysis. Conclusions: Vital capacity was an independent marker of diabetes and associated with MS and hs-CRP in Japanese men. [Copyright &y& Elsevier]
