Purpose The evidence on effects of TV viewing time among premenopausal and postmenopausal women for breast cancer risk remains controversial and limited. Materials and Methods A prospective study encompassing 33,276 (17,568 premenopausal, and 15,708 postmenopausal) women aged 40-79 years in whom TV viewing time, menstrual, and reproductive histories were determined by a self-administered questionnaire. The follow-up was from 1988 to 2009 and hazard ratios (HRs) with 95% confidence intervals (as) of breast cancer incidence were calculated for longer TV viewing time in reference to shorter TV viewing time by Cox proportional hazard models. Results During 16.8-year median follow-up, we found positive associations between TV viewing time and breast cancer incidence with a borderline significant trend among total women and a significant trend among postmenopausal women. Among total women, the multivariable HRs (95% Cis) for risk of breast cancer in reference to < 1.5 hr/day of TV viewing time were 0.89 (0.59-1.34) for 1.5 to < 3.0 hr/day, 1.19 (0.82-1.74) for 3.0 to < 4.5 hr/day, and 1.45 (0.91-2.32) for >= 4.5 hr/day (p for trend=0.053) and among postmenopausal women, the corresponding risk estimates were 1.10 (0.42-2.88), 2.54 (1.11-5.80), and 2.37 (0.926.10) (p for trend=0.009), respectively. Conclusion Prolonged TV viewing time was associated with increased risk of breast cancer, especially among postmenopausal women.

Aim: Previous studies suggested a positive association between eczema and cardiovascular disease (CVD), probably through enhanced systemic inflammation. However, several studies reported null findings about eczema and CVD, so the evidence is still controversial. Methods: We asked 85,099 participants (35,489 men and 49,610 women), aged 40 to 79 years, without a history of CVD or cancer at baseline between 1988 and 1990, to complete a lifestyle questionnaire, including information eczema frequency (seldom, sometimes or often). Results: During the 6,389,818 person-years of follow-up, there were 1,174 deaths from coronary heart disease (CHD), 979 from heart failure, 366 from cardiac arrhythmia, 2,454 from total stroke, 1,357 from ischemic stroke, 1,013 from hemorrhagic stroke, and 201 from aortic aneurysm or dissection. The multivariable-adjusted model showed that individuals who “sometimes” or “often” had eczema had 0.82 (95%confidence interval (CI): 0.69–0.97) or 1.26 (95%CI: 1.01–1.56) times the risk of mortality from CHD, respectively, compared to those who “seldom” did. Individuals who “often” had 1.30 (95%CI: 1.05–1.61) times the risk of mortality from CHD, compared to those who “seldom or sometimes” did. There was no association of eczema with mortality from other CVD, or no interaction between eczema and sex or age, in relation to any CVD mortality risk. Conclusions: Self-reported frequent eczema was associated with increased risk of mortality from CHD, but not other major CVD, in a Japanese general population. Since steroid usage was not considered, future studies should include it as a potential confounding factor.

Aim: The aim of the present study was to clarify that the effects of accumulated experience in end-of-life care and communication skill on the attitudes of care workers’ toward end-of-life care. Methods: A study implemented 2012 to 2014. Two hundred and fifty-three questionnaires were returned (40.2%), and 170 were fully completed by care workers in special nursing homes. We sorted the responses into two groups by experience level: the experienced end-of-life care (EE) group and the inexperience end-of-life care (IE) group. Responses were also sorted by communication skill level: a high score communication (HSC) group and a low score communication (LSC) group. A two-way repeated measure analysis of variance was used for the statistical analysis. Results: The EE group was more likely to be younger (P = .04), to have a longer duration of employment (P < .001), and to have participated in an EOL care seminar in their facility (P = .02) than the IE group. Attitudes toward end-of-life care were significantly different between the EE and IE groups (df = 2, F = 3.35, P < .05). Attitudes toward end-of-life care were not significantly different when comparing the HSC and LSC groups (df = 2, F = 0.17, P = .85). The communication skill between the HSC and LSC groups differed significantly at 2012, 2013, and 2014. Conclusions: The accumulation of end-of-life care experience prompted a positive change in attitudes toward end-of-life care. Meanwhile, communication skill had no significant effect to change attitudes toward end-of-life care.

Objective: Our aim was to estimate whether diabetes mellitus (DM) may be associated with an increased risk of colorectal cancer (CRC) mortality in Japan. Methods: The Japan Collaborative Cohort (JACC) Study is a nationwide prospective study, initiated in 1988, which involves 110,585 subjects (age range: from 40 to 79 years; 46,395 males and 64,190 females). Our present analysis population comprised 96,081 (40,510 men and 55,571 women) who provided details on DM history. The questionnaire also included age, sex, weight, height, family history of CRC, smoking, drinking and exercise habits, and education. Cox proportional-hazard regression was used to estimate the hazard ratio (HR). We used SPSS 21 software to analyze all data. Results: Among the participants with DM, we followed up for 71,174 person-years and 640. deaths from CRC were confirmed; and, among the non-diabetic participants, 785 CRC deaths were identified during 1,499,324 person-years. After adjusting for multivariate confounding factors, such as age, sex, body mass index (BMI), family history of colorectal cancer, smoking habit, drinking habit, physical activity (sports and walking) and education, DM was associated with an increased risk of CRC death (HR 1.4, 95% confidence interval [CI] 1.0-2.0). Diabetic women, but not diabetic men, experienced increased mortality from CRC (HR 1.7, 95% CI 1.0-3.0). Conclusion: The risk of CRC mortality is significantly increased in both sexes and women with diabetes, but no significant increase was seen for diabetic men among Japanese.

Evidence for a link between periodontal disease and several systemic diseases is increasing rapidly. However the relationship of periodontal disease to oral health behavior and oral health knowledge have been studied as extensively. The aim of the present study was to investigate the association of periodontal disease with oral health behavior and oral health knowledge among adult Japanese people. Subjects were 988 persons over 20 years in the eastern part of Hokkaido, Japan. The survey items were age, sex, history of systemic diseases, smoking status, oral health behavior such as frequency of tooth brushing, having a family dentist and so on. Odds ratios (ORs) and their 95% confi dence intervals (CIs) of variables related to having Community Periodontal Index (CPI)≧ 3 were evaluated using the unconditional logistic regression model by sex . Former smoking (OR=1.94, 95%CI: 1.02-3.69) and having no family dentist (OR=2.52, 95%CI: 1.49-4.27) were significantly associated with risk of having CPI≧3 in the male subjects. Not using a toothpaste was marginally signifi cantly associated with risk of having CPI≧3 in the female subjects (OR=1.43, 95%CI: 0.99-2.04). This study suggests that there is a signifi cant relationship of oral health behavior and smoking to periodontal disease.

We aimed to validate the Japanese version of the Aging Males' Symptoms rating scale (JPN-AMS) by using factor analysis. The study included 155 normal men 40 years old and older, and 116 patients who visited our clinic with complaints of aging males' symptoms. Participants self-administered the JPN-AMS. Factor analysis was done to confirm the internal structure of the questionnaire. We found three items that were not among the factors in the original Aging Males' Symptoms rating scale in normal men and seven items that were not the factors in the original scale in the patients who had a serum free testosterone level below 8.5 pg/ml. In particular, 5 of the 7 somatic items seemed not to be associated with the somatic factor. In conclusion, the factor analysis provided a confirmation of the internal structure of the JPN-AMS. We have to be aware of the different internal structure of the JPN-AMS for the Japanese patients with late-onset hypogonadism. Therefore, we should take care to use the JPN-AMS, as there are cultural differences among countries.

Japanese women's anthropometries and their lifestyles have been gradually changing since 1945. Therefore, we conducted a case-control study in order to explore the relationship of anthropometries, physical activity and other risk factors of endometrial cancer (EC) in Japanese women. This study of EC was conducted between January 2003 and March 2008 in Sapporo, Japan. Informed written consent was obtained from 191 patients and 419 population-based control subjects. The items surveyed were body height and weight, physical activity, past history, family history, menstruation, post-menopausal status, reproductive history, and so on. An adjusted odds ratio (OR) and its 95% confidence interval (95%CI) were estimated with the multivariate unconditional logistic regression model. The number of pregnancies (Ptrend=0.004) and number of live-births (Ptrend
