BACKGROUND An association between coffee drinking and reduced risk of liver cancer has been suggested by animal studies, but epidemiologic evidence of such an association in a high-risk population is lacking. We conducted a large-scale population-based cohort study of the association between coffee drinking and hepatocellular carcinoma (HCC) in a Japanese(More)
Trends in the incidence rate of lung cancer by histological type were examined, based on data from the Osaka Cancer Registry (OCR), Japan and the Surveillance, Epidemiology and End Results Program (SEER), USA. Among males, an increasing trend was observed for adenocarcinoma in both registries. In the OCR, the incidence rate of adenocarcinoma has recently(More)
The objective of this study was to evaluate the validity and reproducibility of a self-administered food frequency questionnaire (FFQ) to estimate nutrient and food intake in the subjects of the Japan Public Health Center-based prospective Study on Cancer and Cardiovascular Diseases (JPHC Study Cohort II). The FFQ was originally developed to estimate intake(More)
According to the National Vital Statistics data, age-standardized mortality rates (ASRs) of lung cancer have shown slightly declining trends in Japan for both men and women. In order to evaluate whether this tendency will continue, a Bayesian age-period-cohort (APC) model was applied using the National Vital Statistics data from 1952 to 2001. In the(More)
To evaluate the hypothesis that, in terms of all-cause death, drinking alcohol 1-4 days per week is less harmful than daily (5-7 days/week) drinking of the same quantity of alcohol, a prospective cohort study using a self-administered questionnaire was conducted in Japan between 1990 and 2003 of 88,746 subjects (41,702 men and 47,044 women) aged 40-69 years(More)
The use of a biomarker is mandatory for quantitative analysis of exposure to secondhand smoke (SHS). This article summarizes urinary biomarkers of smoke exposure which can be now quantified. The most reliable urinary biomarkers to assess the exposure to SHS are NNAL 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol and NNAL-Glucuronides, which is metabolites of(More)
The present study was designed to investigate the influence of modifiable risk factors (body weight and lifestyle) for bone loss on bone mineral density (BMD). We examined age-specific changes in metacarpal BMD, and its associations with body mass index and lifestyle among 532 community-dwelling postmenopausal Japanese women. Measurements of the second(More)
To explore how the stiffness index of the calcaneus is related to lifestyle factors, we examined the associations of lifestyle factors, age, and years since menopause, with stiffness index of the calcaneus among 573 community-dwelling Japanese women aged 40-89 years. Stiffness index of the calcaneus was obtained from quantitative ultrasound measurement.(More)
