“…We found that men presented a higher smoking prevalence rate, and this was slightly (1.1%) over the national level (52.0%) in 2001 4) . Takemura et al 31) reported a smoking rate of 49.5% in male clerical workers, which was lower than that in transport (64.5%) or production and labor (54.6%) related occupations. A similar finding was observed in the US population, with only 4.9% prevalence (the lowest) for office workers 32) .…”

suggest that socio-demographic, lifestyle and mental health characteristics are independently associated with current smoking. These factors should be considered in smoking cessation policies as program components. (J Occup Health 2007; 49: 443-452) Key words: Smoking behavior, Socio-demographic factors, Education, Lifestyle, Affect balance scale, Japanese civil servants Tobacco smoking is of great public health concern world-wide [1][2][3] . Although the prevalence of smoking has steadily decreased, from 82.3% (in 1965) to 46.9% (in 2004) in men and from 15.7% (in 1965) to 13.2% (in 2004) in women 4) , the prevalence of smoking among Japanese men is still higher than in other developed countries 5) . Although the prevalence of smoking among Japanese women is lower than in Western countries, it has gradually increased especially among the 20-30 year age group 6, 7) . Recently, in European and American populations, many previous studies have reported that smoking is associated with socio-demographic factors [8][9][10] , low education level [10][11][12][13] , work stress 14,15) and mental health 16,17) . In Japan, some studies have demonstrated a significant correlation between smoking behavior and socio-demographic status 18,19) , low education level 20) , but only a limited range of variables related to smoking behavior have been analyzed in such studies, and many of them did not investigate for possible cofounders. Although some occidental studies have found a positive association between smoking and mental health in males 16,17) , no association was observed in the Japanese surveys 21,22) . The relationship between smoking behavior and possible cofounder factors such as socio-demographic factors, lifestyle, mental health, and work characteristics and so on has not been investigated fully in the Japanese population. The questionnaire included items on socio-demographic factors, education level, grade of employment, lifestyle, affect balance scale, and work characteristics. Smoking status was divided into current smoker, ex-smoker and never smoked. Multiple logistic regression analysis was performed to evaluate the relationship between smoking and the other items. Men presented a higher smoking prevalence rate than women (53.1% vs. 4.9%). In men, a strong relationship between current smoker and advanced age (40 yr or older), low education level, less physical activity, irregular breakfast and negative affect balance was found. Among men with a low education, the prevalence of smoking cessation was significantly lower in comparison to men with a high education. In women, being young (20-29 yr), unmarried (single or other), having a hobby, and irregular breakfast were associated with smoking behavior. Furthermore, smoking cessation was significantly associated with having a hobby and negative affect balance. The above results

“…The prevalence of H. pylori infection in smokers has been reported as low (Ogihara et al 2000), normal (Brenner et al 1997), or high (Parasher and Eastwood 2000). The influence of smoking on the prevalence of chronic bronchitis has also been little understood (Takemura et al 2005). Therefore, in the present study, we also compared the H. pylori infectious status between the current cigarette smokers and never smokers in patients with chronic bronchitis, showing no impact of cigarette smoking on H. pylori infection.…”

“…As the present study was performed under prolonged hypoxic exposure in awake mice, our results may have limited value in explaining the mechanisms of intermittent apnea during sleep in sleep apnea syndrome. However, these findings may be helpful to explain fatal respiratory disturbances observed clinically under hypoxic conditions of various diseases such as chronic obstructive pulmonary disease (Ichinose 2003;Takemura et al 2005) and sleep apnea syndrome (Miki et al 1988;Hida et al 1994;Taguchi et al 1997;Hida 1998).…”

Hypoxia causes a life-threatening situation, and the ventilatory response to hypoxia plays an important role in preventing death. We have hypothesized that persons with a blunted hypoxic ventilatory response may have a weak defense response to hypoxic episodes and be susceptible to fatal respiratory disturbances. However, precise correlations between the hypoxic ventilatory response and respiratory disturbances are not well understood. In the present study we examined the hypoxic and hypercapnic ventilatory responses in nine inbred mouse strains (A/J, AKR/N, BALB/c, C3H/He, C57BL/6, DBA/2, NZW, SWR/J, and 129Sv). Breathing frequency, tidal volume and minute ventilation of unanesthetized and unrestrained mice were assessed by whole body plethysmography. Age-matched mice were exposed for 3 min to 10% O 2 in N 2 gas or 10% CO 2 in hyperoxic gas to determine the acute ventilatory response to chemical stimuli. Basal respiratory variables and hypoxic ventilatory responses differed among the strains, but the hypercapnic ventilatory response did not differ. The hypoxic ventilatory response was the highest in AKR/N mice and the lowest in SWR/J mice. These findings suggest that genetic factors may have influenced the hypoxic ventilatory response but not the hypercapnic ventilatory response. To examine the effects of severe hypoxic stress on the respiratory cycle, we exposed the strain with the highest or lowest hypoxic ventilatory response to 6% O 2 in N 2 until the onset of apnea. The "appearance time of apnea", which is defined as the time from the hypoxic loading to the onset of apnea, was shorter in the SWR/J strain than in the AKR/N strain. We suggest that a lower hypoxic ventilatory response may be a risk factor for apnea under hypoxia.
