In order to estimate the salt and potassium intake in a population and to compare their annual trends, we developed a simple method to estimate population mean levels of 24-h urinary sodium (24HUNaV) and potassium (24HUKV) excretion from spot urine specimens collected at any time. Using 591 Japanese data items from the INTERSALT study as a gold standard, we(More)

We aimed to clarify the relationship of maternal smoking with both SGA and preterm LBW infants. METHODS The study population comprised(More)
Individuals who are physically fit or engage in regular physical activity have a lower incidence of cardiovascular disease and risk of mortality. We conducted a large-scale controlled trial of interventions to decrease cardiovascular risk factors, during which we assessed the effect of a workplace-based intervention program, which was part of a population(More)

RESEARCH DESIGN AND METHODS Data were analyzed from a cohort of participants in the High-Risk and Population Strategy for Occupational Health Promotion Study (HIPOP-OHP) conducted in Japan from 1999 to 2004. Active and passive smoking(More)
AIM It is well established that people gain weight after smoking cessation; however, changes in cardiovascular risk factors and the estimated risk of coronary heart disease following smoking cessation have yet to be fully clarified. METHODS The participants were 1,995 Japanese male workers at 11 workplaces who participated continuously in the High-risk(More)
To test the effectiveness of a low-intensity intervention program for smoking cessation targeting the worksite environment in employees who had a low readiness to quit, we conducted an intervention trial at six intervention and six control worksites in Japan. A total of 2,307 smokers at baseline who remained at their worksite throughout the three-year study(More)
AIM To examine the relationship between the type of work and the number of metabolic syndrome diagnostic components(MetS-DC), as well as the risk of MetS, with adjustment for lifestyle habits in Japanese workers. METHODS We examined the baseline data from 4,427 participants(81.4% male) aged 19 to 69 years old. The physical activity of each participant was(More)

The objective of this study is to investigate the effect of self-reported sleep duration and sleep quality on the risk of developing diabetes in a prospective cohort in Japan. METHODS Data were analyzed from the cohort of participants in a(More)
AIM To examine the relation between lifestyle and the number of metabolic syndrome (MetS) diagnostic components in a general population, and to find a means of preventing the development of MetS components. METHODS We examined baseline data from 3,365 participants (2,714 men and 651 women) aged 19 to 69 years who underwent a physical examination,(More)
