  • Alcohol and breast cancer in women : A pooled analysis of cohort studies
  • 1998
  • Ingår i: Journal of the American Medical Association (JAMA). - 0098-7484 .- 1538-3598. ; 279:7, s. 535-540

    • OBJECTIVE: To assess the risk of invasive breast cancer associated with total and beverage-specific alcohol consumption and to evaluate whether dietary and nondietary factors modify the association. DATA SOURCES: We included in these analyses 6 prospective studies that had at least 200 incident breast cancer cases, assessed long-term intake of food and nutrients, and used a validated diet assessment instrument. The studies were conducted in Canada, the Netherlands, Sweden, and the United States. Alcohol intake was estimated by food frequency questionnaires in each study. The studies included a total of 322647 women evaluated for up to 11 years, including 4335 participants with a diagnosis of incident invasive breast cancer. DATA EXTRACTION: Pooled analysis of primary data using analyses consistent with each study's original design and the random-effects model for the overall pooled analyses. DATA SYNTHESIS: For alcohol intakes less than 60 g/d (reported by >99% of participants), risk increased linearly with increasing intake; the pooled multivariate relative risk for an increment of 10 g/d of alcohol (about 0.75-1 drink) was 1.09 (95% confidence interval [CI], 1.04-1.13; P for heterogeneity among studies, .71). The multivariate-adjusted relative risk for total alcohol intakes of 30 to less than 60 g/d (about 2-5 drinks) vs nondrinkers was 1.41 (95% CI, 1.18-1.69). Limited data suggested that alcohol intakes of at least 60 g/d were not associated with further increased risk. The specific type of alcoholic beverage did not strongly influence risk estimates. The association between alcohol intake and breast cancer was not modified by other factors. CONCLUSIONS: Alcohol consumption is associated with a linear increase in breast cancer incidence in women over the range of consumption reported by most women. Among women who consume alcohol regularly, reducing alcohol consumption is a potential means to reduce breast cancer risk.

  • Serum sialic acid and its correlates in community samples from Akita, Japan and Minneapolis, USA
  • 1997
  • Ingår i: International Journal of Epidemiology. - : Oxford University Press. - 1464-3685. ; 26:1, s. 58-63
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: The concentration of serum total sialic acid (S-TSA) is one recently investigated risk marker for cardiovascular mortality and atherosclerosis. Since the mortality from coronary heart disease is higher in the United States than in Japan, one could expect the S-TSA to be higher among Caucasian US citizens than among Japanese citizens, a hypothesis that is tested in this study. DESIGN: Cross-sectional study of population-based samples of Japanese and US Caucasian men and women. SETTING: The rural community Akita, Japan, and the suburbs of Minneapolis, Minnesota. SUBJECTS: These were 75 consecutive men and women from Akita and Minneapolis respectively aged 47-69 years in 1990. People who had smoked cigarettes during the past 5 years; who had a history of diabetes mellitus, liver disease, coronary heart disease, or stroke; or who were taking anticoagulants were excluded. OUTCOME MEASURES: Serum total sialic acid levels in male and female Japanese and US Caucasian subjects with adjustment for age, systolic blood pressure, fibrinogen, triglycerides and in women also for menopausal status. Race and sex-specific correlations with serum total sialic acid for selected cardiovascular risk markers. RESULTS: The entire sialic acid distributions were shifted to the right in Caucasian men and women compared to Japanese men and women. The mean +/- standard deviation concentrations of S-TSA were 54.1 +/- 5.3 mg/dl in Japanese men and 58.7 +/- 5.6 mg/dl in Caucasian men (P < 0.001). In women, the concentrations were 54.8 +/- 5.1 and 63.1 +/- 6.0 mg/dl respectively (P < 0.001). S-TSA level correlated significantly and positively with fibrinogen levels in Caucasian and Japanese men and women and with triglyceride levels in Caucasian and Japanese men and in Caucasian women but not in Japanese women. After adjustment for age, systolic blood pressure, fibrinogen, triglycerides and menopausal status, the sialic acid levels were 2.2 (P = 0.009) and 6.2 (P < 0.001) mg/dl higher in Caucasian compared to Japanese men and women respectively. CONCLUSIONS: Higher S-TSA levels in Caucasians living in Minneapolis compared to Japanese living in Akita, Japan is in concordance with the higher cardiovascular mortality in the US. Differences in S-TSA levels may reflect international differences in the prevalence of atherosclerosis.

  • The association between serum sialic acid and asymptomatic carotid atherosclerosis is not related to antibodies to herpes type viruses or Chlamydia pneumoniae. The Atherosclerosis Risk in Communities (ARIC) Study Investigators
  • 1997
  • Ingår i: International Journal of Epidemiology. - : Oxford University Press. - 1464-3685. ; 26:6, s. 1386-1391
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Total serum sialic acid is a recently investigated marker for cardiovascular mortality and carotid atherosclerosis. This study tested the hypothesis that past infection by Herpes simplex type 1 or type 2 viruses or Cytomegalovirus or Chlamydia pneumoniae accounts for the association between serum total sialic acid and atherosclerosis. METHODS: Population-based samples of men and women living in four US communities were used in a cross-sectional study. Cases and matched controls were defined by B-mode ultrasound measurements of carotid and popliteal arterial wall thickness. In all, there were 267 case control pairs with information about antibody titres to viruses and 256 pairs with information about antibody titres to Chlamydia pneumoniae. RESULTS: Serum total sialic acid (S-TSA) level was significantly higher in cases with carotid atherosclerosis compared to their controls. The odds ratio for carotid atherosclerosis associated with sialic acid level above 75th percentile was 1.73 (95% confidence interval [CI]: 1.02-2.95) in the sample with information about antibodies to viruses and 1.70 (95% CI: 1.00-2.93) in the sample with information about antibodies to C. pneumoniae. Adjustment for titres of antibodies to viruses and C. pneumoniae had no impact on the relation between sialic acid and carotid atherosclerosis. CONCLUSIONS: From these results, it seems unlikely that previous infection by any of these micro-organisms accounts for the relation between S-TSA level and carotid atherosclerosis.

  • Association between serum sialic acid concentration and carotid atherosclerosis measured by B-mode ultrasound. The ARIC Investigators. Atherosclerosis Risk in Communities Study
  • 1996
  • Ingår i: International Journal of Epidemiology. - : Oxford University Press. - 1464-3685. ; 25:5, s. 953-958
  • Tidskriftsartikel (refereegranskat)abstract
    • 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.
