The association of cigarette smoking with development of hearing impairment (loss of 30 dB at 1000 Hz and 40 dB at 4000 Hz) over a 5-year follow-up was studied in 1554 non-hearing-impaired Japanese male office workers who ranged in age from 30 to 59 years. After controlling for potential predictors of hearing impairment, the relative risk for low-frequency(More)
BACKGROUND The contribution of cigarette smoking to development of impaired fasting glucose and type 2 diabetes remains unclear. OBJECTIVE To investigate the association of cigarette smoking with development of impaired fasting glucose and type 2 diabetes. DESIGN Prospective cohort study. SETTING Work site in Osaka, Japan. PARTICIPANTS 1,266(More)
OBJECTIVE To investigate the association between serum gamma-glutamyltransferase (GGT) and risk for development of diabetes. DESIGN Longitudinal study (followed from 1994 to 2001). SETTING A work site in Japan. SUBJECTS A total of 2918 Japanese male office workers aged 35-59 years who did not have impaired fasting glucose (IFG) (a fasting plasma(More)
OBJECTIVE To estimate the prevalence and risk factors of urinary and fecal incontinence among a community-residing older population in Japan. DESIGN Population-based cross-sectional study. SUBJECTS A randomly selected sample of 1473 people aged 65 years and older living in the City of Settsu, Osaka, in 1992. MEASURES Data collected via in-home visits(More)
Trends in age-specific and age-adjusted blood pressure and the prevalence of hypertension were obtained from the National Nutrition Survey of Japan, 1956-1980. The national trends in the age-adjusted blood pressure of people (30-69 years old) in Japan during the 1956-1980 period show an increasing pattern reaching a peak around 1964 followed by a decreasing(More)
To identify the lifestyle factors responsible for increases in serum gamma-glutamyltransferase (GGT), 1014 hepatobiliary dysfunction-free (no medication for and no past history of liver disease, < or = 39 U/L of serum aspartate and/or alanine aminotransferase, and < or = 59 U/L of serum GGT) Japanese male office workers aged 35-55 years were examined(More)
The potential inverse association between coffee intake and serum gamma-glutamyltransferase (GGT) was examined in a cross-sectional study involving 1353 Japanese male office workers aged 35-59 years in Osaka, Japan. Those who had serum aminotransferases exceeding the normal range and/or who had been administered medical care for, or had a past history of,(More)
OBJECTIVE To investigate the association between duration of overtime and the development of impaired fasting glucose (IFG) or type 2 diabetes mellitus (DM). METHODS A cohort of 1266 Japanese male office workers aged 35-59 years and free of IFG (fasting plasma glucose concentration 6.1-6.9 mmol/l), type 2 DM (fasting plasma glucose concentration of 7.0(More)
The association of lifestyle factors with serum gamma-glutamyltransferase (GGT) was examined in 1176 Japanese male office workers aged 40-59 years. Those who had serum aminotransferase levels exceeding the normal range and/or who took prescription medication for, or had a past history of, liver disease were excluded. From the logistic regression analysis,(More)
To identify the factors responsible for increases in serum uric acid (SUA), a cohort of 1,312 hyperuricemia-free (SUA < 7.5 mg/dL and no medication for hyperuricemia or hypertension) male office workers aged 30 to 52 years were examined annually for 8 successive years. Subjects who were found to have become hyperuricemic (SUA > or = 7.5 mg/dL) or who(More)
