Controversy exists concerning whether or not sex discrimination is the norm in Japan and what will happen with the status of Japanese women. One U.S. scholar was surprised after talking to female students at a Japanese college that only a few of them had a view of their future. It is fair to say that Japanese women are not taught to become…

Nicotine concentration in hair is a useful marker of tobacco exposure. Detection of nicotine in the hair of non-smokers indicates passive smoking. Accurate measurement of nicotine among active and passive smokers can help in smoking cessation programs or programs designed to prevent secondhand smoke exposure. To establish, using high-performance liquid chromatography-ultraviolet detection (HPLC/UV), a hair nicotine cut-off value to distinguish active from passive smokers. Hair samples were collected from randomly chosen Japanese men (n= 192) between 2009 and 2011. Nicotine and cotinine levels in hair were measured using HPLC/UV with column-switching. T-tests and chi-square tests were performed to compare active and passive smokers, while receiver operating characteristic curves were used to evaluate the effectiveness of the cut-off value. There were 69 active smokers and 123 passive smokers. The nicotine and cotinine concentrations in hair were significantly higher in active than in passive smokers (p< 0.01). The area under the curve for nicotine was 0.92. A hair nicotine cut-off value of 5.68 ng/mg, with a sensitivity of 94.2% and specificity of 87.0%, was identified as the optimal cut-off value for separating active from passive smokers. Nicotine and cotinine concentrations in hair clearly distinguished active from passive smokers.

This paper reports the findings of a study that explored characteristics of relationships of Japanese immigrant women partnered both intraculturally and interculturally, and analysed the role of Japanese culture in these relationships. Immigration can cause shifts in interpersonal structures with partners. When there are large discrepancies in gender roles and communication styles between the original and host cultures, the psychological impact on both partners may be significant. However, currently no empirical data are available to support this assumption. Ten cases selected from the 68 medical records of Japanese-speaking women seen at a mental health clinic from September 2001 to September 2004 were analysed. All of the 10 women met DSM IV-TR criteria of major depressive disorder and were taking antidepressants. Half of the 10 women were in intimate intercultural partnered relationships and the remainder of the matched cases were in intracultural relationships at the time of treatment. The two cohorts were matched in age (36.2 and 43.2 years), length of stay in the United States of America (12 and 16.2 years), and length of treatment (1.2 and 1 years). The length of time of the sample in individual psychodynamic psychotherapy ranged from 20 to 317 hours, depending on the intensity of therapy. Inductive data analysis revealed two themes: (1) Lack of awareness of differences in culturally bound communication by Japanese women in intercultural partnerships; (2) Lack of individuality in Japanese women in intracultural partnerships. Neither group appeared to consider relational aspects of partnership, or to make efforts to improve direct communication with their partners. The influence of Japanese culture on gender role and communication styles functions contrary to the mainstream Western culture of the United States of America. In the future, interpersonal elements of cultural differences between host and original cultures in immigration should be considered in

We investigated whether 2 types of personalized health guidance (repeated and single counseling) in the Japanese nationwide cardiovascular prevention system promoted smoking cessation among smokers. The study included 47,745 Japanese smokers aged 40 to 74 years classified into 2 personalized health guidance schemes. After a 1-year follow-up, we compared the rates of smoking cessation between individuals who had received counseling ("supported") and those who had not received counseling ("unsupported"). Using propensity score matching analysis, we estimated the average treatment effect (ATE) of each approach on smoking cessation after balancing out the characteristics between the supported and unsupported groups. The propensity score regression model included age, medical insurance type, weight gain since the age of 20 years, exercise, eating habits, alcohol intake, quality of sleep, readiness to modify lifestyle, willingness to receive support, and body mass index. In the repeated counseling scheme, the age-adjusted rates of smoking cessation in the supported and unsupported groups were 8.8% and 6.3% for males, and 9.8% and 9.1% for females respectively. In the single counseling scheme, the corresponding rates were 8.4% and 7.3% for supported and unsupported males, and 11.0% and 11.7% for supported and unsupported females respectively. The ATE of repeated counseling was ＋2.64% (95% confidence interval: ＋1.51% to ＋3.77%) for males and ＋3.11% (－1.85% to ＋8.07%) for females. The ATE of single counseling was ＋0.61% (－1.17% to ＋2.38%) for males and －1.06% (－5.96% to ＋3.85%) for females. In the Japanese cardiovascular prevention system, repeated counseling may promote smoking cessation among male smokers.

This study tests hypotheses concerning ethnic disparities in daily cigarette smoking rates, nicotine dependence, cessation motivation, and knowledge and past use of cessation methods (e.g., counseling) and products (e.g., nicotine patch) in a multiethnic sample of smokers in Hawaii. Previous research has revealed significant differences in smoking prevalence among Native Hawaiians, Filipinos, Japanese, and Caucasians in Hawaii. However, no study has examined differences in dependence and cessation-related knowledge and practices among smokers representing these ethnic groups. Participants were recruited through newspaper advertisement as part of a larger smoking cessation intervention study. Participants (N = 919; M age = 45.6, SD = 12.7; 48 % women) eligible to participate provided self-report data through mail and telephone. Participants included 271 self-identified Native Hawaiians, 63 Filipinos, 316 Caucasians, 145 "East Asians" (e.g., Japanese, Chinese), and 124 "other" (e.g., Hispanic, African-American). Pair-wise comparisons of means, controlling for age, gender, income, education, and marital status, indicated that Native Hawaiian smokers reported significantly higher daily smoking rates and higher levels of nicotine dependence compared to East Asians. Native Hawaiian smokers reported significantly lower motivation to quit smoking than Caucasians. Further, Filipino and Native Hawaiian smokers reported lesser knowledge of cessation methods and products, and less frequent use of these methods and products than Caucasians. The results suggest that Native Hawaiian and Filipino smokers could be underserved with regard to receiving cessation-related advice, and may lack adequate access to smoking cessation products and services. In addition, cessation interventions tailored for Native Hawaiian smokers could benefit from a motivational enhancement component.

The representation of women in Japanese academic medicine is not evident. We aimed to assess trends related to the proportion of female first authors in Japanese cardiovascular journals.We reviewed original research articles in 6 journals published in English by Japanese societies between 2006 and 2015 related to cardiovascular fields. We conducted a multivariable logistic regression analysis to assess the factors associated with the gender of first authors and plotted the trend of predicted probability for female first authors over the study period. Of 7,005 original articles, 1,330 (19.0%) had female first authors. Affiliations located in Japan (adjusted odds ratio [aOR], 0.76; 95% confidence interval [CI], 0.71-0.81), concurrent first and corresponding authors (aOR, 0.69; 95% CI, 0.64-0.74), and the total number of listed authors (aOR, 0.97; 95% CI, 0.95-0.99) were negatively associated with female first authors. The adjusted probability of a female first author increased from 13% to 20% on an average between 2006 and 2009, but the increase reached a plateau after 2010.Female first authors of original research articles published in Japanese cardiovascular journals increased over the examined decade. However, the representation of women is still low and has plateaued in recent years. A gender gap in authorship for Japanese cardiovascular journals remains.

Recent studies have suggested that the association between smoking and breast cancer risk might be modified by polymorphisms in the N-acetyltransferase 2 gene (NAT2). Most of these studies were conducted in Western countries, with few reports from East Asia. We conducted a case-control study of 511 breast cancer cases and 527 unmatched healthy controls from December 2010 to November 2011 in Japan. Unconditional logistic regression was used to analyze the association of smoking with breast cancer risk stratified by NAT2 phenotype. In this population, 11 % of the cases and 10 % of the controls were classified as a slow acetylator phenotype. Compared to never smokers, current smokers had an increased breast cancer risk in multivariate analysis [odds ratio (OR) = 2.27, 95 % confidence interval (95 %CI) = 1.38-3.82]. Subgroup analyses of menopausal status indicated the same tendency. Subgroup analyses of NAT2 phenotype, the ORs in both of rapid and slow acetylator phenotype subgroups were comparable, and no interactions were observed between smoking status and NAT2 phenotype (p = 0.97). A dose-dependent effect of smoking on breast cancer risk was seen for the rapid acetylator phenotype, but not for the slow acetylator phenotype. Given the high frequency of the rapid acetylator phenotype, these results show that smoking is a risk factor for breast cancer among most Japanese women. It may be of little significance to identify the NAT2 phenotype in the Japanese population.

Female smoker's present increased susceptibility to several diseases when compared to the opposite gender. However, there are no studies showing differences in nasal mucociliary transport behavior between male and female smokers. To compare the nasal mucociliary transportability in male and female smokers and non-smokers, taking into consideration age, anthropometric data, smoking load and pulmonary function. The analysis included 139 individuals (33 men and 37 women smokers and 32 men and 37 women non-smokers). All participants answered an initial interview to obtain personal data and smoking load. Anthropometric data and carbon monoxide in the exhaled air were assessed. Individuals also performed pulmonary function test and Saccharin Transit Time test. To compare saccharin transit time values between men and women, smokers and non-smokers, stratification of all independent variables was performed (sociodemographic, smoking and respiratory variables) into two categories: below and above the median values. There was no difference between men and women, smokers and non-smokers, regarding nasal mucociliary transportability. Significant differences were only observed between non-smokers. Among those with less forced vital capacity values (<97.37% of predicted), women presented mucociliary transport faster than men. Moreover, it was observed influence of BMI and COex (women smokers), FCV and FEV1 (men non-smokers) and FEF 25-75% (women non-smokers) on saccharin transit time values. Based on the findings of this study, nasal mucociliary transport in male and female adult smokers, apparently healthy, are similar.

In postmenopausal hypertensive women (PostMHW) the erythrocyte deformability (ED) is reduced if compared with premenopausal hypertensive women (PreMHW). This might partially explain the increased incidence of cardiovascular diseases (CD) in hypertensive women after menopause. Moreover a positive correlation exists between estradiol and rheological patterns in women. If PostMHW smoke cigarettes, there is an important decrease in hemorheological parameters. On the other hand if PostMHW are submitted to an hormonal replacement therapy (HRT) they can show controversial results with an impairment if hemorheological parameters. The aim of this study was to evaluate the influence of smoking and HRT on PostMHW. We studied four groups of subjects: Group 1: PreMHW (10 F aged 35 +/- 3 years) non smokers; Group 2: PostMHW (8 F aged 45 +/- 2 years) non smokers; Group 3: PostMHW (14 F aged 48 +/- 4 years) smokers (20 cigarettes per day); Group 4: PostMHW (16 F aged 50 +/- 2 years) smokers (20 cigarettes per day) submitted to HRT. We evaluated Elongation Index of erythrocytes under torsion force of 30 pascals (EI--30 Pa) using a new computerized instrument Laser assisted Optical rotational Red Cell Analyzer (LORCA) (Mechatronics, Hoorn, NL) acc. to Hardeman (1994) and, also with the same LORCA, Aggregation Index (AI), t(1/2). We measured the transcutaneous oxygen partial pressure (TcpO2) in subclavicular standard area using a Transcutaneous Oximeter (Microgas 7650 Kontron Instruments with Combi Sensor) and total cholesterolaemia. In PostMHW our data showed a significant (p < 0.01) impairment of hemorheological patterns and tissue oxygenation if compared with PreMHW (Group 1). In Group 3 there is a significant (p < 0.01) decrease in EI, a significant (p < 0.01) increase in AI, a significant (p < 0.01) decrease in t(1/2) and TcpO2 if compared with Control Group 1 and Group 2. Finally a further significant (p < 0.01) impairment in hemorheology and tissue oxygenation showed Group 4

Background Japanese (both in Japan and Hawaii) have a lower incidence of falls and of hip fracture than North American and European Caucasians, but the reasons for these differences are not clear. Subjects and Methods A cross-sectional study. We compared neuromuscular risk factors for falls using performance-based measures (chair stand time, usual and rapid walking speed, and grip strength) among 163 Japanese women in Japan, 681 Japanese-American women in Hawaii and 9403 Caucasian women in the United States aged 65 years and over. Results After adjusting for age, the Caucasian women required about 40% more time to complete 5 chair stands than either group of Japanese. Walking speed was about 10% slower among Caucasians than native Japanese, whereas Japanese-American women in Hawaii walked about 11% faster than native Japanese. Grip strength was greatest in Japan, which may reflect the rural farming district that this sample was drawn from. Additional adjustment for height, weight or body mass index increased the adjusted means of chair stand time and grip strength among Japanese, but the differences remained significant. Conclusions Both native Japanese and Japanese-American women in Hawaii performed better than Caucasians on chair stand time and walking speed tests, and native Japanese had greater grip strength than Japanese in Hawaii and Caucasians. The biological implications of these differences in performance are uncertain, but may be useful in planning future comparisons between populations. PMID:11696243

To investigate the involvement of psychological/social factors in the condition of climacteric disturbance in Japan and the Philippines, we examined the menopausal symptoms and psychological/social factors in menopausal women living in local communities and compared among both countries whether differences in culture, lifestyle, etc. affected the condition of climacteric disturbance. High percentages of Japanese women reported mental symptoms, while relatively high percentages of Filipino women also experienced motor neurological symptoms in addition to psychoneurological symptoms. Japanese and Filipino women were found to have different stressors: a high percentage of the Japanese women had problems involving human relationships, such as providing nursing care, while a high percentage of the Filipino women had household problems, including husband's health and financial problems. Stress severity was associated with SMI scores in both countries. A poorer marital relationship in Japan than in the Philippines and an association between marital relationship and SMI scores were found. The present study suggests the association of differences in psychological/social factors between Japanese and Filipino women with differences in menopausal symptoms.

Objective To examine the consequences of early-onset hearing loss on several social and health measures and any related gender differences in Japanese populations. Methods Data from a 2007 nationally representative cross-sectional household survey of 136,849 men and women aged 20 to 39 years were obtained (prevalence of self-reported hearing loss: 0.74%). We focused particularly on four social and health measures: employment status (employed/unemployed), marital status (married/unmarried), smoking behavior (yes/no), and psychological distress (K6 instrument: ≥ 5 or not). We examined the association of hearing loss for each measure using generalized estimating equations to account for correlated individuals within households. Findings There was no significant association with employment status (p = 0.447). Men with hearing loss were more likely to be married, whereas women with hearing loss were less likely to be married (p < 0.001 for interaction). Although hearing loss was not associated with a current smoking status in men, women with hearing loss were more likely to be current smokers (p < 0.001 for interaction). Moreover, hearing loss was associated with psychological distress in men and women (both p < 0.001). Conclusion These findings suggest that hearing loss is related to social and health issues in daily life, including a lower likelihood of marriage, more frequent smoking, and poorer mental health, especially in women. These issues may reflect a gap between the actual needs of women with hearing loss and the formal support received as a result of existing public health policies in Japan. PMID:25651532

Intimate partner violence (IPV) is a problem in Japan. The purpose is to describe IPV as perceived by a purposive sample of 11 Japanese adult females who were in a heterosexual marriage at the time of IPV. We used a cross-sectional, retroactive, qualitative description research design with individual, fact-to-face in depth interviews. At the time of the interview, the women had a mean age of 38 years and at the time of the IPV, a mean age of 28 years. Data were analyzed using the directed qualitative content analysis method. The results revealed that all women experienced physical and emotional abuse and 82% experienced sexual abuse. Communication between spouses was characterized as unilateral, with husbands initiating and dominating the conversation. The women identified the culture of the Japanese patriarchal system as directly influencing IPV. The implication is health professionals should actively advocate for effective legislation and policies to address IPV.

This article addresses gender-related stresses of working women in Japan. We conducted a study of 399 employees in Japan using the National Institute for Occupational Safety and Health General Job Stress questionnaire. The results suggest that for women the most significant factor related to depression is interpersonal conflict, whereas for men, it is professional matters. In addition, we conducted interviews with Japanese female employees about their occupational stress. Our interviews indicated that for the occupational mental health of working women, the establishment of modified and supportive interpersonal relations within workplace environments may be required because of the gender roles expected of women in a male-dominant socioculture.

To find CEA levels in smokers of different categories (hookah smokers, cigarette smokers smoking different brands of cigarettes and different number of cigarettes per day) and to correlate CEA levels with type and rate of smoking. A total of 122 cigarette smokers (115 men and 7 women) and 14 hookah smokers (all men) with age ranging from 16-80 years were studied. CEA levels were also measured in 36 non-smokers who served as controls. Enhanced chemilumiscent immunometeric technique was applied to measure CEA levels in our subjects. The mean CEA levels of cigarette smokers were compared with the mean CEA levels observed in hookah smokers (7.16 +/- 10.4 ng/ml) and non-smokers (2.15 +/- 0.68 ng/ml). The mean value of CEA level observed in cigarette smokers, 9.19 +/- 14.9 ng/ml (n=122) was significantly higher than the levels in non-smokers and hookah smokers (p < 0.0067). It was also observed that CEA levels increased with the number of cigarettes smoked per day. The highest levels were observed in smokers who smoke more than 31 cigarettes per day. The smokers that use relatively cheaper brands of cigarettes had higher levels of CEA compared to those who use high quality brands. It was concluded that the brands of cigarettes (which were ranked on the basis of price) and the rate of smoking both play an important role in raising the CEA levels. Further the common belief that hookah also called narghile or shisha is a relatively safe mode of smoking is not completely correct; a significant proportion of hookah smokers have high levels of CEA although mean levels of hookah smokers were low compared to cigarette smokers.

Previous studies have reported that spousal non-smoking has a spillover effect on the partner's cessation. However, discussion is lacking on the factors modifying that association. We examined whether the spillover effect of spousal non-smoking was associated with the couple's educational attainment. We used paired marital data from the Japanese Study on Stratification, Health, Income, and Neighborhood (J-SHINE), which targeted residents aged 25-50 years in four Japanese municipalities. We selected a spouse smoker at the time of marriage (target respondent), and set his/her smoking status change (continued or quit smoking after marriage) as an outcome, regressed on the counterpart's smoking status (continued smoking or non-smoking) and combinations of each couple's educational attainment as explanatory variables using log-binomial regression models (n =1001 targets; 708 men and 293 women). Regression results showed that a counterpart who previously quit smoking or was a never-smoker was associated with the target male spouse's subsequent cessation. However, for women, the association between husband's non-smoking and their own cessation was significant only for couples in which both spouses were highly educated. Our findings suggest that a spouse's smoking status is important for smoking cessation interventions in men. For women, however, a couple's combined educational attainment may matter in the interventions.

Two open-label randomized cross-over studies in Japanese smokers investigated the single-use nicotine pharmacokinetic profile of the Tobacco Heating System (THS) 2.2, cigarettes (CC) and nicotine replacement therapy (Gum). In each study, one on the regular and one on the menthol variants of the THS and CC, both using Gum as reference, 62 subjects were randomized to four sequences: Sequence 1: THS - CC (n = 22); Sequence 2: CC - THS (n = 22); Sequence 3: THS - Gum (n = 9); Sequence 4: Gum - THS (n = 9). Plasma nicotine concentrations were measured in 16 blood samples collected over 24 h after single use. Maximal nicotine concentration (C max ) and area under the curve from start of product use to time of last quantifiable concentration (AUC 0-last ) were similar between THS and CC in both studies, with ratios varying from 88 to 104% for C max and from 96 to 98% for AUC 0-last . Urge-to-smoke total scores were comparable between THS and CC. The THS nicotine pharmacokinetic profile was close to CC, with similar levels of urge-to-smoke. This suggests that THS can satisfy smokers and be a viable alternative to cigarettes for adult smokers who want to continue using tobacco. Copyright © 2017 The Authors. Published by Elsevier Inc.

In Studies 1 and 2, there was a linear dose-dependent increase in DRSP C(max) and systemic exposure across the range of doses used in both ethnic groups. The co- administration of EE had no relevant effect on the pharmacokinetic parameters of 3 mg DRSP. In Study 3, steady-state DRSP concentrations were achieved after about eight days of treatment in both ethnic groups with approximately a threefold accumulation. There was about a twofold EE accumulation over 21 days in both ethnic groups. There were no differences in DRSP or EE exposure at day 21 between ethnic groups; the ratio of the geometric means (Japanese/Caucasian) of the AUC(0-24h) were 1.05 (90% CI: 0.95-1.17) and 1.02 (90% CI: 0.76-1.38), respectively. Ethnic origin had no clinically relevant influence on the pharmacokinetics of DRSP and EE.

The Hilo Women's Health Survey was designed and administered to gather baseline data on women's health in Hilo, HI. This randomized, cross-sectional study allowed for a focus on ethnic differences in symptom reporting. The results presented here focus on hot flash and night sweat experience among Japanese-American and European-American women. Survey packets were mailed to street addresses associated with parcel numbers pulled randomly from Hilo tax maps. Of the 6,401 survey packets delivered to households, 1,824 questionnaires were completed and returned. The results reported here are based on 869 women aged 40 to 60, of whom 249 described themselves to be 100% Japanese and 203 described themselves to be 100% European-American. Logistic regression analyses were used to examine whether the relationship between ethnicity and vasomotor symptoms persisted after controlling for other variables. European-American participants were more likely to have ever experienced a hot flash as compared with Japanese-American participants (72% vs 53%, P<0.01). During the 2 weeks before the survey, European-American participants were more likely to have experienced hot flashes (P<0.05) and night sweats (P<0.01). In logistic regression analyses, after controlling for age, body mass index, menopause status, level of education, financial comfort, smoking habits, alcohol intake, exercise, use of hormone therapy, and soy intake, European-American women were still significantly more likely to have experienced hot flashes (odds ratio=1.858) and night sweats (odds ratio=2.672). The results, based on self-reporting of menopausal symptoms, indicate that Japanese-American women report fewer hot flashes and night sweats than European-American women. Japanese-American women reported a higher intake of soy, but soy intake was not associated with fewer vasomotor symptoms.

To examine the phenomenon of non-smokers spontaneously taking action to seek help for smokers; to provide profiles of non-smoking helpers by language and ethnic groups. A large, statewide tobacco quitline (California Smokers' Helpline) in operation since 1992 in California, providing free cessation services in English, Spanish, Mandarin, Cantonese, Korean, and Vietnamese. Callers between August 1992 and September 2005 who identified themselves as either white, black, Hispanic, American Indian, or Asian (n = 349,110). A subset of these were "proxies": callers seeking help for someone else. For more detailed analysis, n = 2143 non-smoking proxies calling from October 2004 through September 2005. Proportions of proxies among all callers in each of seven language/ethnic groups; demographics of proxies; and proxies' relationships to smokers on whose behalf they called. Over 22 000 non-smoking proxies called. Proportions differed dramatically across language/ethnic groups, from mean (+/-95% confidence interval) 2.7 (0.3)% among English-speaking American Indians through 9.3 (0.3)% among English-speaking Hispanics to 35.3 (0.7)% among Asian-speaking Asians. Beyond the differences in proportion, however, remarkable similarities emerged across all groups. Proxies were primarily women (79.2 (1.7)%), living in the same household as the smokers (65.0 (2.1)%), and having either explicit or implicit understandings with the smokers that calling on their behalf was acceptable (90.0 (1.3)%). The willingness of non-smokers to seek help for smokers holds promise for tobacco cessation and may help address ethnic and language disparities. Non-smoking women in smokers' households may be the first group to target.

The present study examined whether the three major functions of autobiographical memory observed in Western societies (i.e., directing-behaviour, social-bonding and self-continuity) also exist in an East Asian society. Two self-report measures were used to assess the autobiographical memory functions of Japanese men and women. Japanese young adults (N = 451, ages 17-28 years) first completed the original Thinking About Life Experiences (TALE) Questionnaire. They subsequently received three TALE items that represented memory functions and attempted to recall a specific instance of memory recall for each item. Confirmatory factor analyses on the TALE showed that the three functions were replicated in the current sample. However, Japanese participants reported lower levels of all three functions than American participants in a previous study. We also explored whether there was an effect of gender in this Japanese sample. Women reported higher levels of the self-continuity and social-bonding functions than men. Finally, participants recalled more specific instances of memory recall for the TALE items that had received higher ratings on the TALE, suggesting that the findings on the first measure were supported by the second measure. Results are discussed in relation to the functional approach to autobiographical memory in a cross-cultural context.

To identify the prevalence of intimate partner violence (IPV) against Japanese women (JW) and non-Japanese women (NJW) in a perinatal setting. Additional purposes were to identify the associated factors of IPV, describe the characteristics of IPV against NJW, and assess the acceptability of the Violence Against Women Screen (VAWS) instrument as a screening tool. A cross-sectional survey was conducted from September to November 2007 in an urban hospital maternity clinic in Tokyo, Japan. Women who attended the maternity clinic received the VAWS instrument, which was translated into four languages (Japanese with Kanji and Hiragana, English, Chinese, and Tagalog) and was used to identify IPV. A total of 400 women participated in the study: 357 were JW and 43 were NJW. The prevalence rate of IPV among the JW was 31.4% and 21.4% among the NJW. There was no statistical significance between the two groups. A multiple logistic regression with adjusted odds ratio identified two associated factors for IPV: being multipara and previous experience of physical violence from a partner. The prevalence of IPV was not statistically different among JW and NJW. Screening for IPV, early intervention, and support should be expanded in hospitals and maternity clinics in Japan.

This research was part of a larger mixed-methods study examining culture, distress, and help seeking. We surveyed 209 Japanese women living in the United States recruited from clinic and community-based sites, and carried out semi-structured ethnographic interviews with a highly distressed subsample of 25 Japanese. Analytic Ethnography revealed that women described themselves as a “self-in-context,” negotiating situations using protective resources or experiencing risk exposure. Women experienced quality of life (QOL) when they were successful. However, a related goal of achieving Ikigai (or purpose in life) was differentiated from QOL, and was defined as an ongoing process of searching for balance between achieving social and individual fulfillment. Our resulting hypothetical model suggested that symptom level would be related to risk and protective factors (tested for the full sample) and to specific risk and protective phenomenon (tested in the distressed subsample). The t tests in the full sample found that women who were above threshold for depressive symptoms (n = 26) had higher social stressor and lower social support means. Women who were above the threshold for physical symptoms (n = 99) had higher social stressor means. Analysis of the interviewed subsample found that low self-validation and excessive responsibilities were related to high physical symptoms. We conclude that perceived lack of balance between culturally defined, and potentially opposing, markers of success can create a stressful dilemma for first-generation immigrant Japanese women, requiring new skills to achieve balance. Perceptions of health, as well as illness, are part of complex culturally based interpretations that have implications for intervention for immigrant Japanese women living in the United States.

While Japanese diets have attracted considerable attention because of, for example, the long-life expectancy in Japan, their health benefits have not been examined. In the present study, we cross-sectionally examined whether adherence to the food-based Japanese dietary guidelines is associated with metabolic risk factors in 1083 Japanese women aged 18-22 years. Based on the Japanese Food Guide Spinning Top, adherence to the food-based Japanese dietary guidelines was assessed using dietary information on consumed servings of grain dishes, vegetable dishes, fish and meat dishes, milk and fruits and energy from snacks and alcoholic beverages during the preceding month, which was derived from a comprehensive diet history questionnaire. Higher dietary adherence was associated with higher intakes of protein, carbohydrate, dietary fibre, Na, K and vitamin C, and lower intakes of total and saturated fat. There was also an inverse association between dietary adherence and dietary energy density. After adjustment for potential confounding factors, dietary adherence was inversely associated with waist circumference (P for trend = 0·002). It also showed an inverse association with LDL-cholesterol concentrations (P for trend = 0·04). There was no association with the other metabolic risk factors examined, including BMI, systolic and diastolic blood pressure, total and HDL-cholesterol, TAG, glucose, glycated Hb and insulin concentrations. In conclusion, higher adherence to the food-based Japanese dietary guidelines, which was characterised by favourable dietary intakes of foods and nutrients as well as lower energy density, was associated with lower waist circumference and LDL-cholesterol concentrations in this group of young Japanese women.

In this study, we identified the factors influencing behavioral intention to undergo Papanicolaou testing among Japanese and Korean women in early adulthood. Their behavioral intentions were compared in this cross-sectional descriptive study. In total, 887 women (Japanese = 498, Korean = 389) aged 20-39 years participated in this study. Using a self-report questionnaire, knowledge, attitudes, subjective norm, perceived behavioral control, and behavioral intention were surveyed. There were significant differences between Japanese and Korean women's scores on all main variables. For Japanese women, all the variables moderately correlated with behavioral intention. In comparison, for Korean women, all independent variables, except for knowledge, moderately correlated with behavioral intention. Through a multiple regression analysis, age, undergoing Papanicolaou testing, attitudes, subjective norm, and perceived behavioral control were identified as significant predictors of behavioral intention among Japanese women. Among Korean women, job status, undergoing a Papanicolaou test, attitudes, subjective norm, and perceived behavioral control were demonstrated as significant predictors of behavioral intention. Health professionals should consider these factors to encourage Papanicolaou testing in women in early adulthood. © 2017 John Wiley & Sons Australia, Ltd.

There is limited information about the respiratory function of ever-smokers without lung disorders. We sought to assess the effects of smoking habits on respiratory function in subjects without lung disorders. Subjects were recruited from among patients without any evidence of respiratory disorders who visited rural primary care clinics. Each participant was asked to answer a questionnaire that included questions smoking history. Their forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) were measured. We analyzed 802 subjects (364 men and 438 women). The means of the lambda-mu-sigma method derived z-score of FEV1 (zFEV1) both in current-smokers and ex-smokers were lower than that in never-smokers. The mean zFEV1 in the ever-smokers with more than 30 pack-years of smoking history were lower than that in the ever-smokers with less smoking history. Univariate analysis showed that there were significant negative correlations between pack-years and zFEV1 both in the ex-smokers and current-smokers. There was no significant correlation between the duration of smoking cessation and zFEV1 in the ex-smokers. Our data suggests that respiratory function in healthy ever-smokers is decreased based on smoking habits in a dose-dependent manner. Even after a long period of smoking cessation, the decreased respiratory function seems to be maintained in ex-smokers. Copyright © 2017 The Japanese Respiratory Society. Published by Elsevier B.V.

Bone mineral density (BMD) of total body, spine, and proximal femur and the percentage of body fat in 151 U.S.-born Japanese-American women and 137 Japan-born immigrant Japanese-American women living in San Diego, California were measured using dual-energy x-ray absorptiometry. These data were compared with unpublished data from Japanese women obtained in previous studies in Hamamatsu, Japan. The age-adjusted BMD for the spinal level, femoral neck, Ward's triangle, trochanter, and total body, respectively, of U.S.-born Japanese-American women were 10.2, 9.8, 9.9, 9.2, and 2.7% higher than those of native Japanese women. The U.S.-born Japanese-American women had significantly higher body fat than immigrant Japanese-American women. Furthermore, the immigrant women had higher BMD and higher body fat than their native Japanese counterparts; however, no significant total-body BMD differences were found among the three groups after age, height, and weight were adjusted. The U.S.-born Japanese-American women had BMD values equivalent to those of white normals at the spine and femur. Significant life-style differences between U.S.-born and immigrant Japanese-American women were noted. Weight, exercise, early menarche, and years of lifetime estrogen exposure correlated positively with BMD. The significant negative correlates of BMD were age, smoking, and percentage of body fat. Our study presents data suggesting that immigration to the United States has produced a higher BMD in Japanese-American women that is attributable to changes in life-style and diet.

In Japan, in comparison with the rest of the world the death rate of lung cancer is low although the smoking rate is relatively high. This is the so-called "Japanese smoking paradox". A healthy diet is proposed to attenuate the risk without quitting smoking. We here examined the relationships between smoking status (SS) and the consumption of food and nutrient in Japan. Totals of 5,587 men and 2,718 women were divided into three (non-smokers, smokers and heavy smokers) and two (non-smokers and smokers) groups, respectively, according to pack-year, which represents the amount of smoking over a long period. Food and nutrient consumption was estimated with a validated food frequency questionnaire. Using general linear models, food and nutrient consumption was estimated for each group in men and women, separately. In men, SS was positively related to consumption of rice, 3 alcoholic beverages, carbohydrate, alcohol and other 8 foods/nutrients (p<0.05 for all) and negatively to those of protein animal, fat, fatty acids, dietary fiber, isoflavones and 36 other foods/nutrients (p<0.05 for all). In women, SS was positively associated with intake of 13 foods/nutrients, while being negatively associated with those of rice, energy, dietary fiber, and 14 other foods/nutrients (p<0.05 for all). Our results support lower intake of vegetables and fruits rich in antioxidants, which are thought as preventive factors for many diseases, in smokers.

The current and future contraceptive needs of Japanese women.

Kobayashi, T

Between 1945-1948, the population of Japan increased by 5 million people. Further, between 1947-1950, 2.7 million recorded births occurred each year resulting in the population growing from 72-83.2 million. The crude birth rate fell from a high of 34.3 in 1947 to a low of 11.1 in 1986. The population is expected to increase from 117-130 million (1090-2010) and then fall to and stabilize at 118 over 70 years. 80% of married women in Japan want to have 2-3 children. In 1984, 59% of married women used a family planning method and 83.1% ever used such a method. In 1979, the condom was the leading contraceptive among married couples (82%) followed by the rhythm method (23%). Since 1948 japanese women have been able to obtain a legal abortion. 600,000 induced abortions occur annually in Japan today. Even though the number of abortion have fallen steadily from 1955, the percentage of abortions among teenagers has increased from 1.6-4.7% between 1975-1985. Japanese would like to reverse this trend and the expected approval of oral contraceptives (OCs) could help do so. In 1979, only 3% of married couples depended on OCs. A concern of OCs many people worldwide held for many years was the cardiovascular risk of the high dose OCs. In Japan, however, the rate of thrombosis is lower than it is among Europeans and Americans. Thus Japanese women appear to be suitable candidates for Ocs, but, in 1986, 52% of married women had not formed an opinion on the pending approval of OCs. Further 43% said they would not use an OC. These results indicated a great need for OC education as well as for education on all contraception. Since 99% of all births occur under the guidance of skilled health workers, the health workers could inform women about contraceptives, but often are too busy to do so.

Few studies have examined the individual and social impact of smoking behavior in the Japanese population. The purpose of this study was to clarify the association between smoking behavior and socio-demographic factors, lifestyle, mental health and work characteristics of Japanese civil servants. A self-administered questionnaire survey of 1,439 employees (821 men and 618 women) aged 20-64 yr was conducted in a local government department in 2001. 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 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.

Profile of Maternal Smokers Who Quit During Pregnancy: A Population-Based Cohort Study of Tasmanian Women, 2011-2013.

Smoking remains the single-most significant preventable cause of poor pregnancy outcomes, yet around 12% of Australian women smoke during pregnancy. Many women are motivated to quit when they find out they are pregnant, yet few are successful. While previous studies have examined the profile of the maternal smoker compared to her nonsmoking counterpart (Aim 1), little is known about what differentiates women who quit during pregnancy to those who do not (Aim 2). Here, we present results from a study investigating the characteristics of women who were able to quit during pregnancy. Data were drawn from the Tasmanian Population Health database of women who had received antenatal care between 2011 and 2013 (n = 14300). Data collected included age, relationship status and ethnicity of expectant mothers, antenatal details, mental health conditions, and drug use. Independent samples t tests were used to compare differences between women who had, and those who had not, quit during pregnancy. The 19.4% of women who self-reported as smoking in the first half (first 20 weeks) of their pregnancy were further grouped and analyzed comparing those who reported still smoking in the second half of their pregnancy (smokers: n = 2570, 92.4%) to those who quit (quitters: n = 211, 7.6%). Quitters (57.8%) were more likely to be in a relationship than their non-quitting counterparts (49.6%, p = .022) and were less likely to suffer from postnatal depression (2.4% vs. 6.0%, p = .029). No other differences between quitters and smokers were observed. Determining the profile of women who are able to quit during pregnancy may be important to improve the relatively poor cessation rates among maternal smokers and may assist in more effectively targeting at-risk women. Smoking cessation interventions have traditionally targeted socially disadvantaged women, for good reason: the majority of smoking pregnant women fall into this category. However, despite the significant attention and resources

We previously reported a cross-sectional analysis regarding the relationship between smoking and atrial fibrillation (AF) in a single hospital-based cohort with Japanese patients, but the effect of cessation of smoking and/or total tobacco consumption were unclear. We used data from the Shinken Database 2004-2011 (men/women, n=10,714/6803, respectively), which included all new patients attending the Cardiovascular Institute between June 2004 and March 2012. After excluding those previously diagnosed with AF (n=2296), 15,221 patients (men/women, n=9016/6205) were analyzed. During the follow-up period of 2.0±2.1 years (range 0.0-8.1), the incidence rates of new AF in smokers and non-smokers were 9.0 and 5.0 per 1000 patient-years, respectively. In adjusted models with Cox regression analysis, smokers were independently associated with new AF [hazard ratio (HR) 1.47, 95% confidence interval (CI) 1.09-2.00]. Also, current smokers (HR 1.81, 95% CI 1.17-2.79) and smokers with Brinkman index ≥800 (HR 1.69, 95% CI 1.05-2.70) were independently associated with new AF. However, in current smokers, the HRs were not different by Brinkman index (Brinkman index <800/≥800; HR 1.81/1.82, 95% CI 1.07-3.05/0.94-3.51, respectively). Smoking was independently associated with the first-appearance of AF in patients in sinus rhythm, especially when the patients continued their smoking habit. However, in patients who continued smoking, difference by total tobacco consumption was not observed, suggesting the significance of cessation of smoking for preventing AF. Our data are limited because of a single hospital-based nature and a relatively short observation period. Copyright © 2014 Japanese College of Cardiology. Published by Elsevier Ltd.

Background: Exposure to cadmium has been suspected as a risk factor for breast cancer. The present study examined the associations between urinary cadmium levels and circulating sex hormone levels that are linked to breast cancer risk in healthy women. Methods: The study subjects were 396 premenopausal Japanese women who had regular menstrual cycles less than 40 days long and 207 postmenopausal Japanese women. Urinary cadmium was measured using spot urine samples. Plasma estradiol, testosterone, and dehydroepiandrosterone sulfate were measured. Additionally, the follicle-stimulating hormone, luteinizing hormone, and sex hormone-binding globulin were measured for premenopausal women. Results: In premenopausal women, the urinarymore » cadmium level either expressed in μg per liter or per g of urine creatinine was significantly inversely associated with total and free testosterone levels after controlling for age, body mass index, smoking status, alcohol intake, and the phase of the menstrual cycle. Total and free testosterone levels were 14.6% and 15.0% lower, respectively, in women in the highest quartile of urinary cadmium per g creatinine in those in the lowest quartile. In postmenopausal women, the urinary cadmium in μg per liter as well as per g creatinine was significantly inversely associated with the estradiol level after controlling for covariates. The estradiol level was 25.8% lower in women in the highest tertile of urinary cadmium per g creatinine than in those in the lowest tertile. Conclusions: The data suggest inverse associations between urinary cadmium and the plasma estradiol or testosterone level in Japanese women. - Highlights: • Exposure to cadmium has been suspected as a risk factor for breast cancer. • Urinary cadmium and plasma sex-hormone levels were measured in Japanese women. • Urinary cadmium was inversely associated with testosterone in premenopausal women. • Urinary cadmium was inversely associated with estradiol in

Polymorphisms in cytokine genes can influence immune responses to human papillomavirus infection, possibly modifying risks of cervical cancer. Using an amplification refractory mutation system-polymerase chain reaction method, we analyzed a single nucleotide polymorphism (A/G) at position -1082 in interleukin-10 promoter region in 440 Japanese women: 173 women with normal cytology, 163 women with cervical intraepithelial neoplasia and 104 women with invasive cervical cancer. The carrier frequency of interleukin-10 -1082 G alleles associated with higher interleukin-10 production increased with disease severity: 9.8% for normal cytology; 19.6% for cervical intraepithelial neoplasia; 29.8% for invasive cervical cancer (P for trend < 0.001). Among cytologically normal women, human papillomavirus infections were more common in those who were positive for an interleukin-10 -1082 G allele (P = 0.04). In conclusion, our data suggest that interleukin-10 -1082 gene polymorphism may serve as a marker of genetic susceptibility to cervical cancer among Japanese women.

We report that infertile women in Japan as well as in the Western world have high levels of emotional distress, anxiety, and depression. The reasons for anxiety and depression in infertile women are easy to presume but remain unclear. We conducted the present study to assess the relationship between the anxiety and depression of infertile Japanese women and their thought processes and emotional well-being with regard to their infertility. A cross-sectional questionnaire was administered to 101 infertile Japanese women who visited the infertility clinic at Tokai University. Inventories included the Hospital Anxiety and Depression Scale (HADS) and our original infertility questionnaire, which is composed of 22 questions to assess attitudes and emotional status in facing the stigma of infertility. After factor analysis, comparison between the HADS and the infertility questionnaire was made with simultaneous multiple regression analyses. Anxiety and depression in childless Japanese women were significantly associated with lack of husband's support and feeling stress. Our findings should prove useful in designing and implementing psychological support programs for infertile Japanese women. Psychological interventions to relieve or diminish these conditions might have significant therapeutic benefits for women attending infertility clinics in Japan.

The purpose of this study was to evaluate the ethnic difference in bone mass between Japanese and Inner Mongolian young premenopausal women and to assess the contribution of lifestyle related and anthropometric factors to bone mass. We studied 33 Japanese and 44 Inner Mongolian healthy young women, aged 20-34 years, in urban area. Speed of sound (SOS), broadband ultrasound attenuation (BUA) and stiffness index (SI) were measured at the calcaneus using quantitative ultrasound (QUS) analysis. Age at menarche, regularity of menstruation and lifestyle related factors were estimated by a self-reported questionnaire. There were no differences between the two groups in age, height, weight, BMI, regularity of menstruation, frequency of meat intake, frequency of yellow-green vegetable intake and exercise habit. Japanese women had significantly lower age at menarche and higher proportion of milk consumption habit at junior high school, senior school and present. Before adjustment, Japanese women had significantly higher SOS and SI than Inner Mongolian women. However, after adjustment for age at menarche and milk consumption habit at junior high school, both of which were significantly different between groups, no group-differences remained in either SOS or SI. These results suggest that the differences in age at menarche and milk consumption habit at junior high school, which relate to hormonal and nutritional status during puberty, may account for the differences in bone mass between Japanese and Inner Mongolian young women.

Humans and other living organisms require small quantities of trace elements throughout life. Both insufficient and excessive intakes of trace elements can have negative consequences. However, there is little information on serum level of trace elements in different populations. This study examines serum levels of trace elements in Ethiopian, Japanese, and Vietnamese women. Random samples of healthy women who were referred for routine hospital laboratory examinations in the cities of Hanoi, Sapporo, and Gondar were invited to participate in the study. Serum levels of magnesium, zinc, copper, iron, selenium, and calcium were determined using an inductively coupled plasma mass spectrometer. Furthermore, body mass index of each study participant was determined. The mean ± SD serum concentrations of zinc (μg/dL), copper (μg/dL), iron (μg/dL), selenium (μg/dL) and calcium (mg/dL), respectively, were 76.51 ± 39.16, 152.20 ± 55.37, 385.68 ± 217.95, 9.15 ± 4.21, and 14.18 ± 3.91 in Ethiopian women; 111.49 ± 52.92, 105.86 ± 26.02, 155.09 ± 94.83, 14.11 ± 3.41, and 11.66 ± 2.51 in Vietnamese women; and 60.69 ± 9.76, 107 ± 156, 268 ± 128, 8.33 ± 3.65, and 11.18 ± 0.68 in Japanese participants. Ethiopian women had significantly higher level of serum calcium than Vietnamese and Japanese women (both P < 0.05). Although the mean calcium concentration in Vietnamese women was higher than in women from Japan, the difference was not statistically significant (P > 0.05). Furthermore, compared with Japanese women, Ethiopian women had significantly high iron and copper concentrations (P < 0.05). Serum selenium and zinc levels were higher in Vietnamese than Ethiopian women. The study revealed a remarkable difference in serum concentrations of trace elements in women from different countries, implying differences in trace elements in the food or soil.

Background We examined the risk of hypertensive disorders in relation to maternal depressive and anxiety disorders which were diagnosed before or during early pregnancy in Japanese women. Methods We reviewed the obstetric records of all Japanese singleton deliveries at ≥ 22 weeks’ gestation managed at the Japanese Red Cross Katsushika Maternity Hospital between 2009 and 2014. Potential risk factors for hypertensive disorders with maternal depressive and anxiety disorders were selected as follows: maternal age, parity, medications, self-interruption of medications and economic problems. Results The incidence of hypertensive disorders did not increase in the pregnant women with depressive disorders compared with that in the normal control pregnant women (P = 0.96). However, the incidence of hypertensive disorders in the women with anxiety disorders was higher than that in the control women (odds ratio (OR): 2.61, 95% confidence interval (CI): 1.4 - 5.0, P < 0.01). In the women with anxiety disorders, 19% performed self-interruption of medications during pregnancy, and it was associated with the increased risk of hypertensive disorders (vs. no medication group, OR: 7.50, 95% CI: 1.5 - 38, P = 0.03; vs. medication group, OR: 16.0, 95% CI: 2.4 - 110, P < 0.01). Conclusions Maternal uncontrolled anxiety disorders due to self-interruption of medications seemed to be associated with the increased risk of hypertensive disorders in Japanese pregnant women.

Based on the analysis of 16 interviews with women first-year master's students at two national engineering schools in Japan, this article examines the socialisation role of compulsory undergraduate research experience in Japanese women's decisions to pursue graduate education and choices of the programme. The findings suggest that research experiences in a small independent research unit within the major department convinced Japanese women engineering students of their academic and social success as graduate students in the current environment. Although participants generally adapted themselves to the research unit through their research, there is a variation in the degree to which they were smoothly integrated into the research unit, reflecting organisational and individual differences.

Recombinant hCG (r-hCG) was approved in Japan in 2016. As a prerequisite for a Phase III study in Japan related to this approval, the pharmacokinetic (PK) profile of r-hCG was investigated. An open-label, partly randomized, single-center, single-dose, group-comparison, Phase I PK-bridging study was done that compared a single 250 μg dose of r-hCG with a single 5000 IU dose of urinary hCG (u-hCG) in healthy Japanese women, as well as comparing a single 250 μg dose of r-hCG in Japanese and Caucasian women. The Japanese participants were randomized 1:1 to receive either r-hCG or u-hCG, while the Caucasian participants were weight-matched to the Japanese participants who were receiving r-hCG in a 1:1 fashion. The primary PK parameters were the area under the serum concentration-time curve from time 0 extrapolated to infinity (AUC 0-∞ ) and the maximum serum concentration (C max ). The mean serum hCG concentration-time profiles of r-hCG in the Japanese and Caucasian participants were a similar shape, but the level of overall exposure was ~20% lower in the Japanese participants. For the Japanese participants, r-hCG resulted in an 11% lower C max but a 19% higher AUC 0-∞ compared with u-hCG. No new safety signal was identified. This study cannot exclude a potential difference in the PK profile of r-hCG between Japanese and Caucasian participants. However, this study does not indicate that there are clinically relevant differences in the serum PK of r-hCG and u-hCG in the Japanese participants.

The Japanese Food Guide Spinning Top was developed by the Japanese Ministry of Health, Labor, and Welfare and the Ministry of Agriculture, Forestry, and Fishery to promote healthful diets. Adherence to the Japanese Food Guide Spinning Top was evaluated in terms of future mortality in a prospective cohort study. A prospective cohort study among men and women in a general Japanese population. The cohort consisted of 13,355 men and 15,724 women residing in Takayama, Japan, in 1992. At baseline, a food frequency questionnaire was administered, and adherence to the food guide was measured based on consuming the recommended number of servings of grains, vegetables, fish and meat, milk, and fruits, as well as total daily energy intake and energy from snacks and alcoholic beverages. Higher scores indicated better adherence to the recommendations on a scale of 0 to 70. Based on data obtained from the Office of the National Vital Statistics, deaths occurring among members of the cohort were prospectively noted from 1992 to 1999. To assess the magnitude of association of adherence scores with subsequent mortality, a Cox proportional hazard model was applied to estimate hazard ratios (HRs) with 95% confidence intervals (CIs). Among women, the adherence score was significantly associated with a lower risk of mortality from all causes (comparing highest and lowest quartiles of the score, HR 0.78, 95% CI 0.65 to 0.94, P for trend 0.01) in a multivariate analysis; noncardiovascular, noncancer causes (HR 0.69, 95% CI 0.50 to 0.96, P for trend 0.04) and cardiovascular disease (HR 0.76, 95% CI 0.56 to 1.04, P for trend0.05). No statistically significant association was observed between the adherence score and mortality among men. The results suggest that diets based on the food guide have the benefit of reducing future mortality in women.

Opioid antagonism of cannabinoid effects: differences between marijuana smokers and nonmarijuana smokers.

Haney, Margaret

2007-06-01

In non-human animals, opioid antagonists block the reinforcing and discriminative-stimulus effects of Delta(9)-tetrahydrocannabinol (THC), while in human marijuana smokers, naltrexone (50 mg) enhances the reinforcing and subjective effects of THC. The objective of this study was to test a lower, more opioid-selective dose of naltrexone (12 mg) in combination with THC. The influence of marijuana-use history and sex was also investigated. Naltrexone (0, 12 mg) was administered 30 min before oral THC (0-40 mg) or methadone (0-10 mg) capsules, and subjective effects, task performance, pupillary diameter, and cardiovascular parameters were assessed in marijuana smoking (Study 1; n=22) and in nonmarijuana smoking (Study 2; n=21) men and women. The results show that in marijuana smokers, low-dose naltrexone blunted the intoxicating effects of a low THC dose (20 mg), while increasing ratings of anxiety at a higher THC dose (40 mg). In nonmarijuana smokers, low-dose naltrexone shifted THC's effects in the opposite direction, enhancing the intoxicating effects of a low THC dose (2.5 mg) and decreasing anxiety ratings following a high dose of THC (10 mg). There were no sex differences in these interactions, although among nonmarijuana smokers, men were more sensitive to the effects of THC alone than women. To conclude, a low, opioid-selective dose of naltrexone blunted THC intoxication in marijuana smokers, while in nonmarijuana smokers, naltrexone enhanced THC intoxication. These data demonstrate that the interaction between opioid antagonists and cannabinoid agonists varies as a function of marijuana use history.

The aim of this present study was to compare the use by smokers and non-smokers of pamphlets about smoking as delivered from different settings. The study was a nation-wide cross-sectional survey of 1924 randomly selected, Danish men and women, aged 14-77 y, who had answered a mailed questionnaire in 1994. Of these 71% also participated in a telephone interview enquiring about the use of health education material, smoking status and socio-demographic variables, 39% of readers of household-delivered anti-smoking pamphlets reported having gained information from them and 22% reported having made changes in their own smoking behaviour such as avoiding smoking in the presence of non-smokers. In general practice settings, these percentages were higher among smokers. Smokers who were thinking of stopping smoking in the near future were in addition more likely to take and to read smoking related health education materials from other places. Non-smokers received (3 49%) and read pamphlets about smoking as frequently as did smokers who did not intend to quit. In conclusion, written health education material was well received by readers, but, when distributed in a more open setting it needs to be targeted towards smokers who are considering stopping smoking. In general practice, smokers not thinking of stopping were open to health education, and pamphlets used in this setting should also target this group. Non-smokers contribute indirectly to smokers quitting by providing support to smokers and pamphlets for non-smokers need to be more targeted towards this social role.

Bone mineral density (BMD) and physical performance of the lower extremities decrease with age. In community-dwelling Japanese women, unipedal standing time, timed up and go test, and age are associated with BMD while in women aged 70 years and over, unipedal standing time is associated with BMD. The aim of this study was to clarify whether unipedal standing time is significantly associated with BMD in community-dwelling women. The subjects were 90 community-dwelling Japanese women aged 54.7 years. BMD of the second metacarpal bone was measured by computed X-ray densitometry. We measured unipedal standing time as well as timed up and go test to assess physical performance of the lower extremities. Unipedal standing time decreased with increased age. Timed up and go test significantly correlated with age. Low BMD was significantly associated with old age, short unipedal standing time, and long timed up and go test. Stepwise regression analysis revealed that age, unipedal standing time, and timed up and go test were significant factors associated with BMD. In 21 participants aged 70 years and over, body weight and unipedal standing time, but not age, were significantly associated with BMD. BMD and physical performance of the lower extremities decrease with older age. Unipedal standing time, timed up and go test, and age are associated with BMD in community-dwelling Japanese women. In women aged 70 years and over, unipedal standing time is significantly associated with BMD.

Depression is strongly associated with daily smoking. Yet, little is known about the association between depression and non-daily smoking. The aim of this study was to investigate the prevalence of past-year depression and changes in past-year depression over time among non-daily smokers, compared to daily smokers and never-smokers, overall and stratified by age, gender, income, nicotine dependence, and cigarettes per day. Data were drawn from the National Household Survey on Drug Use (NSDUH), an annual cross-sectional study of persons aged 12 and over (total study population N = 496 805). The prevalence of past-year depression was examined annually among non-daily smokers, daily smokers, and never-smokers from 2005 to 2013 using linear trend analyses. Past-year depression was common among 10.10% of non-daily smokers, common among 10.78% of daily smokers, and 5.51% of never-smokers in 2013. The prevalence of depression increased from 2005 to 2013 among non-daily smokers (9.06% vs. 10.10%; p = .034) while there was no significant change in depression over time among daily smokers. Increases in depression among non-daily smokers occurred for both men and women and appear most pronounced youth, those smoking fewer cigarettes, and those without nicotine dependence. The prevalence of depression among non-daily smokers was equivalent to daily smokers and nearly twice that among nonsmokers. Depression appears to be increasing over time in non-daily smokers especially among youth, those who smoke less, and those without nicotine dependence. More work on the mental health of non-daily smokers is needed as this is an increasing and understudied group. This is the first study to investigate changes in the prevalence of depression among non-daily smokers compared to daily smokers and never-smokers over the past decade in a nationally representative sample of the United States. The results suggest an increase in depression among non-daily smokers over time that did not

Although an osteoporosis screening program has been implemented as a health promotion project in Japan, its cost-effectiveness has yet to be elucidated fully. We performed a cost-effectiveness analysis and found that osteoporosis screening and treatment would be cost-effective for Japanese women over 60 years. The purpose of this study was to estimate the cost-effectiveness of osteoporosis screening and drug therapy in the Japanese healthcare system for postmenopausal women with no history of fracture. A patient-level state transition model was developed to predict the outcomes of Japanese women with no previous fracture. Lifetime costs and quality-adjusted life years (QALYs) were estimated for women who receive osteoporosis screening and alendronate therapy for 5 years and those who do not receive the screening and treatments. The incremental cost-effectiveness ratio (ICER) of the screening option compared with the no screening option was estimated. Sensitivity analyses were performed to examine the influence of parameter uncertainty on the base case results. The ICERs of osteoporosis screening and treatments for Japanese women aged 50-54, 55-59, 60-64, 65-69, 70-74, and 75-79 years were estimated to be $89,242, $64,010, $40,596, $27,697, $17,027, and $9771 per QALY gained, respectively. Deterministic sensitivity analyses showed that several parameters such as the disutility due to vertebral fracture had a significant influence on the base case results. Applying a willingness to pay of $50,000 per QALY gained, the probability that the screening option became cost-effectiveness estimated to 50.9, 56.3, 59.1, and 64.7 % for women aged 60-64, 65-69, 70-74, and 75-79 years, respectively. Scenario analyses showed that the ICER for women aged 55-59 years with at least one clinical risk factor was below $50,000 per QALY. In conclusion, dual energy X-ray absorptiometry (DXA) screening and alendronate therapy for osteoporosis would be cost-effective for

Several previous studies have shown that a diet score based on the Japanese food guide Spinning Top (the original score) is associated with both favourable and unfavourable dietary intake patterns. We developed a food-based diet quality score (the modified score) and examined associations with nutrient intakes. Subjects were 3963 young (all aged 18 years), 3800 middle-aged (mean age 47·7 (sd 3·9) years) and 2211 older (mean age 74·4 (sd 5·2) years) Japanese women. Dietary intakes were assessed using comprehensive (for the young and middle-aged) and brief-type (for the older) diet history questionnaires. The original score was calculated based on intakes of grains, vegetables, fish/meat, milk, fruits, and snacks/alcoholic beverages. The modified score was similarly calculated, but included Na from seasonings and without applying the upper cut-off values for dietary components where increased consumption is advocated for Japanese women (grains, vegetables, fish/meat, milk, and fruits). The original score was positively associated with intakes of carbohydrate, dietary fibre, and all the vitamins and minerals examined including Na and inversely with intakes of fats and alcohol in young and middle-aged women. In older women, the original score was inversely associated with intakes of all nutrients except for carbohydrate and vitamin C. However, the modified score was associated positively with intakes of protein, carbohydrate, dietary fibre, K, Ca, Mg, Fe, vitamins A, C and E, and folate and inversely with intakes of fats, alcohol and Na in all generations. In conclusion, the modified diet score was positively associated with favourable nutrient intake patterns in Japanese women.

Change in Body Weight Does Not Mediate the Relationship Between Exercise and Smoking Cessation Among Weight-Concerned Women Smokers

Introduction: Exercise has received attention as a method to prevent or reduce postcessation weight gain. However, little is known about how weight changes following quit attempts contribute to the relationship between exercise and smoking cessation. The present study assessed how exercise relates to cessation and whether initial changes in exercise after quitting smoking promote cessation through attenuated weight gain. Methods: Weight-concerned women smokers (N = 342) receiving cessation treatment provided biochemical validation of cessation, reported weekly exercise activities, and were weighed at 1, 3, and 6 months following treatment initiation. Survival analyses were used to determine time to and risk of relapse among women who reported engaging in varied levels of exercise at baseline. A mediation analysis was used to examine whether the effect of initial changes in exercise on longer-term cessation was driven by change in weight. All analyses were adjusted for relevant covariates. Results: Women smokers who reported high levels of exercise at baseline were less likely to relapse and returned to smoking more gradually than did women who reported low levels of exercise. Change in weight did not mediate the relationship between exercise and cessation. Conclusions: Cessation interventions utilizing an exercise component may have to develop exercise regimens of either higher duration or greater intensity to produce beneficial cessation outcomes, particularly when targeting sedentary smokers. Given that change in weight did not mediate the relationship between exercise and cessation, it is likely that other mediational processes are involved. PMID:25542920

Breast density often affects cancer detection via mammography (MMG). Because of this, additional tests are recommended for women with dense breasts. This study aimed to reveal trends in breast density among Japanese women and determine whether differences in breast density differentially affected the detection of abnormalities via MMG. We retrospectively analyzed 397 control women who underwent MMG screening as well as 269 patients who underwent surgery for breast cancer for whom preoperative MMG data were available. VolparaDensity™ (Volpara), a three-dimensional image analysis software with high reproducibility, was used to calculate breast density. Breasts were categorized according to the volumetric density grade (VDG), a measure of the percentage of dense tissue. The associations between age, VDG, and MMG density categories were analyzed. In the control group, 78% of women had dense breasts, while in the breast cancer group, 87% of patients had dense breasts. One of 36 patients with non-dense breasts (2.7%) was classified as category 1 or 2 (C-1 or C-2), indicating that abnormal findings could not be detected by MMG. The proportion of patients with breast cancer who had dense breasts and were classified as C-1 or C-2 was as high as 22.3%. The proportions of Japanese women with dense breasts were high. In addition, the false-negative rate for women with dense breasts was also high. Owing to this, Japanese women with dense breasts may need to commonly undergo additional tests to ensure detection of breast cancer in the screening MMG.

The purpose of this study was to determine positive and negative social interactions experienced by infertile Japanese women. Semi-structured interviews were conducted with 24 infertile women. The informants were asked about their experiences of positive (helpful) and negative (unhelpful) social interactions with members of their social networks, excluding their partners, with regard to their infertility. Nine positive social interaction categories were clarified, including listening closely to the distress experienced in infertility and treatment, not prying or interfering with the topic of children and respecting the women's decision regarding fertility treatment and taking a wait-and-see attitude. Nine negative social interaction categories were also identified, including prying with the topic of children, showing a negative attitude toward infertility or reproductive medicine, being criticized for not having children and avoiding contact. The present findings systematically and qualitatively determined the positive and negative social interactions experienced by infertile Japanese women within their social networks. This is essential knowledge for medical staff to counsel patients and their family members. To form a supportive social environment for infertile women, we recommend practical measures for health workers and helpful advice with regard to interactions between infertile women and their social networks.

This study aimed to calculate the prevalence of pre-pregnancy nondaily smoking (<1 cigarette/day), risk factors, and report of prenatal provider smoking education; and assess the likelihood of prenatal cessation and postpartum relapse for nondaily smokers. We analyzed data from 2009 to 2011 among women with live-born infants participating in the Pregnancy Risk Assessment Monitoring System. We compared characteristics of pre-pregnancy daily smokers (≥1 cigarette/day), nondaily smokers, and nonsmokers (chi-square adjusted p < .025). Between nondaily and daily smokers, we compared proportions of prenatal cessation, postpartum relapse (average 4 months postpartum), and reported provider education. Multivariable logistic regression calculated adjusted prevalence ratios (APR) for prenatal cessation among pre-pregnancy smokers (n = 27 360) and postpartum relapse among quitters (n = 13 577). Nondaily smokers (11% of smokers) were more similar to nonsmokers and differed from daily smokers on characteristics examined (p ≤ .001 for all). Fewer nondaily smokers reported provider education than daily smokers (71.1%, 86.3%; p < .001). A higher proportion of nondaily compared to daily smokers quit during pregnancy (89.7%, 49.0%; p < .001), and a lower proportion relapsed postpartum (22.2%, 48.6%; p < .001). After adjustment, nondaily compared to daily smokers were more likely to quit (APR: 1.65; 95% confidence interval [CI]: 1.58-1.71) and less likely to relapse postpartum (APR: 0.55; 95% CI: 0.48-0.62). Nondaily smokers were more likely to quit smoking during pregnancy, less likely to relapse postpartum, and less likely to report provider education than daily smokers. Providers should educate all women, regardless of frequency of use, about the harms of tobacco during pregnancy, provide effective cessation interventions, and encourage women to be tobacco free postpartum and beyond. Nondaily smoking (<1 cigarette/day) is increasing among US smokers and carries a significant

Smoking is one of the most important risk factors for myocardial infarction. Smokers usually suffer their first myocardial infarction earlier in life compared to non-smokers. This age difference seems to be greater in women than in men. The aim of this study was to examine the age and sex differences in terms of smoking in patients with first myocardial infarction who were enrolled in the Swiss National Registry of myocardial infarction, AMIS Plus. Data of 15,711 patients admitted to an AMIS Plus hospital between 1999 and 2008 with a first myocardial infarction were analysed. Several multivariate regression, interaction and sensitivity analyses were conducted. The mean age at first myocardial infarction was 68.5 ± 12.2 years for non-smokers and 56.6 ± 11.7 years for smokers (P < 0.001). After stratification by sex the difference between non-smokers and smokers was 10.2 years in men and 13.1 years in women. Even after adjustment for risk factors (overweight, hypertension, dyslipidaemia, diabetes), comorbidities (peripheral vascular disease, cerebrovascular disease, chronic lung disease), regular cardiovascular medication intake before admission, Killip classification and ECG on admission, male smokers were 8.7 years younger than male non-smokers at first myocardial infarction. In women, the age difference between smokers and non-smokers was 10.8 years, giving a sex-specific difference of 2.1 years (P < 0.001). In the AMIS Plus cohort, smoking was associated with younger age at first myocardial infarction and this was much more pronounced in women. Public health campaigns should take into account the impact of smoking on premature first myocardial infarction, especially in women.

Two studies assessed the effect of a low-estrogen-dose 21/7-day oral contraceptive containing ethinylestradiol and drospirenone (EE 20 mcg/drsp 3 mg) on ovarian activity in Japanese and Caucasian women. Study 1 was conducted in Japanese women (20-35 years), and Study 2 was conducted in Caucasian women (18-35 years). All women received EE 20 mcg/drsp 3 mg in a 21-day active pill regimen. The primary endpoint was the proportion of women with ovulation inhibition (Hoogland score <6; as assessed by transvaginal ultrasonography) during treatment cycle 2. Japanese (n=23) and Caucasian (n=30) women received two cycles of study treatment. During treatment cycle 2, ovulation was inhibited in 100% and 92.9% of Japanese and Caucasian women, respectively. EE 20 mcg/drsp 3 mg in a 21/7-day regimen provides comparable ovarian suppression in Japanese and Caucasian women, with normal ovarian function resuming shortly after treatment end in both populations.

Epidemiological evidence on the relationship between IL1A and/or IL1B polymorphisms and periodontal disease is inconsistent. We investigated associations between three IL1 single-nucleotide polymorphisms (SNPs) in genes encoding interleukin (IL) -1α (rs1800587) and IL-1β (rs1143634 and rs16944) and the risk of periodontal disease among young Japanese women. A case-control study was performed with a total of 1150 women, including 131 subjects who had at least one tooth with a probing pocket depth of 4 mm or deeper and 1019 periodontally healthy controls. Compared with a reference group of women with the GG genotype of SNP rs16944, those with the GA genotype had a significantly reduced risk of periodontal disease, while there was no significant relationship between the AA genotype and periodontal disease. No evident relationships were observed between SNP rs1800587 or rs1143634 and periodontal disease. Our study did not reveal any evidence of interaction between the IL1 polymorphisms and smoking. The results of this study showed that the heterozygous variant genotype of the IL1 rs16944 was significantly associated with a reduced risk of periodontal disease in young Japanese women. Smoking did not significantly modify the gene-disease associations under study.

This study aimed to develop and cross-validate prediction equations for estimating appendicular skeletal muscle mass (ASM) and to examine the relationship between sarcopenia defined by the prediction equations and risk factors for cardiovascular diseases (CVD) or osteoporosis in Japanese men and women. Subjects were healthy men and women aged 20-90 years, who were randomly allocated to the following two groups: the development group (D group; 257 men, 913 women) and the cross-validation group (V group; 119 men, 112 women). To develop prediction equations, stepwise multiple regression analyses were performed on data obtained from the D group, using ASM measured by dual-energy X-ray absorptiometry (DXA) as a dependent variable and five easily obtainable measures (age, height, weight, waist circumference, and handgrip strength) as independent variables. When the prediction equations for ASM estimation were applied to the V group, a significant correlation was found between DXA-measured ASM and predicted ASM in both men and women (R 2  = 0.81 and R 2  = 0.72). Our prediction equations had higher R 2 values compared to previously developed equations (R 2  = 0.75-0.59 and R 2  = 0.69-0.40) in both men and women. Moreover, sarcopenia defined by predicted ASM was related to risk factors for osteoporosis and CVD, as well as sarcopenia defined by DXA-measured ASM. In this study, novel prediction equations were developed and cross-validated in Japanese men and women. Our analyses validated the clinical significance of these prediction equations and showed that previously reported equations were not applicable in a Japanese population.

Ulcerative colitis in smokers, non-smokers and ex-smokers

PubMed Central

Bastida, Guillermo; Beltrán, Belén

2011-01-01

Smoking is a major environmental factor that interferes in the establishment and clinical course of ulcerative colitis (UC). Firstly, the risk of smoking status impact in the development of UC is reviewed, showing that current smoking has a protective association with UC. Similarly, being a former smoker is associated with an increased risk of UC. The concept that smoking could have a role in determining the inflammatory bowel disease phenotype is also discussed. Gender may also be considered, as current smoking delays disease onset in men but not in women. No clear conclusions can be driven from the studies trying to clarify whether childhood passive smoking or prenatal smoke exposure have an influence on the development of UC, mainly due to methodology flaws. The influence of smoking on disease course is the second aspect analysed. Some studies show a disease course more benign in smokers that in non-smokers, with lower hospitalizations rates, less flare-ups, lower use of oral steroids and even less risk of proximal extension. This is not verified by some other studies. Similarly, the rate of colectomy does not seem to be determined by the smoking status of the patient. The third issue reviewed is the use of nicotine as a therapeutic agent. The place of nicotine in the treatment of UC is unclear, although it could be useful in selected cases, particularly in recent ex-smokers with moderate but refractory attacks of UC. Finally, the effect of smoking cessation in UC patients is summarised. Given that smoking represents a major worldwide cause of death, for inpatients with UC the risks of smoking far outweigh any possible benefit. Thus, physicians should advise, encourage and assist UC patients who smoke to quit. PMID:21734782

Little research has been conducted to examine the effect of inconsistencies in socioeconomic status on cardiovascular health. In particular, no studies have been reported in Asian countries, including Japan, which is thought to have high socioeconomic status inconsistency among women. We examined the effect of status inconsistency between education level and occupation on stroke risk in a prospective 20-year study of 14 742 middle-aged Japanese women included in the prospective Japan Public Health Center-based (JPHC) Study Cohort I in 1990. Status inconsistency between education level and occupation was determined (qualified, overqualified, and underqualified), and the association with risk of stroke was examined. Cox proportional regression analysis was used to determine hazard ratios, which were adjusted for age, marital status, and geographical area. Adjusted hazard ratio for stroke in overqualified compared with qualified women was 2.06 (95% confidence interval, 1.13-3.78). Adjusted hazard ratios for stroke among highly educated manual workers and workers in service industry were 3.47 (95% confidence interval, 1.54-7.84) and 3.21 (95% confidence interval, 1.49-6.90), respectively, when compared with highly educated professionals/managers. High academic qualifications without an appropriate job could be a risk factor for stroke among Japanese women. Our result suggests that status inconsistency could be a potential explanation for the increased stroke risk among highly educated women. © 2014 American Heart Association, Inc.

"Comfort women" refers to young women and girls who were forced into sexual slavery by the Imperial Japanese military during World War II. They were abducted from their homes in countries under Imperial Japanese rule, mostly from Korea, and the rest from China, Philippines, Malaysia, Taiwan, Indonesia, the Netherlands, etc. "Comfort women" endured extreme trauma involving rape, sexual torture, physical abuse, starvation, threats of death, and witnessed many others being tortured and killed. This article reviews all the studies that have investigated the psychiatric or psychosocial sequelae of the survivors of the Japanese military sexual slavery. Most importantly, a recent study which conducted a psychiatric evaluation on the former "comfort women" currently alive in South Korea is introduced. The participants' unmarried rate was relatively high and their total fertility rate was relatively low. Majority of the participants reported having no education and being the low economic status. They showed high current and lifetime prevalence of posttraumatic disorder, major depressive disorder, somatic symptom disorder, social anxiety disorder, panic disorder, and alcohol use disorder. Participants showed high suicidality and majority of the participants still reported being ashamed of being former "comfort women" after all these years. This article high-lights the fact that the trauma has affected the mental health and social functioning of former "comfort women" throughout their lives, and even to the present day.

The aim of this study was to examine the relation of lifestyle to the metabolic syndrome in Japanese male workers. The association of 6 lifestyle factors with the metabolic syndrome and the prevalence of the metabolic syndrome, as defined by the modified International Diabetes Federation criteria for Japanese people, were evaluated in 4941 men at a workplace participating in the annual health examination mandated by law; the subjects ranged in age from 36 to 60 years. The overall prevalence of the metabolic syndrome in the sample was 9.1%. The prevalence was the highest in subjects aged 46-50 years. The odds ratios (95% confidence interval) of the metabolic syndrome in current smokers and ex-smokers compared with non-smokers were 1.381 (1.088-1.752) (P=.008) and 1.812 (1.365-2.407) (P<.001), respectively. In contrast, no preventive effect of alcohol on the occurrence of the metabolic syndrome was noted.

Variations in Carboxyhaemoglobin Levels in Smokers

Castleden, C. M.; Cole, P. V.

1974-01-01

Three experiments on smokers have been performed to determine variations in blood levels of carboxyhaemoglobin (COHb) throughout the day and night and whether a random measurement of COHb gives a true estimation of a smoker's mean COHb level. In the individual smoker the COHb level does not increase gradually during the day but is kept within relatively narrow limits. Moderately heavy smokers rise in the morning with a substantially raised COHb level because the half life of COHb is significantly longer during sleep than during the day. Women excrete their carbon monoxide faster than men. A random COHb estimation gives a good indication of the mean COHb level of an individual. PMID:4441877

2017-06-01

Only a few studies have focused on the association between overall diet, rather than intakes of individual nutrients or foods, and depressive symptoms in Japanese. This cross-sectional study examined associations between a diet quality score and depressive symptoms in 3963 young (age 18 years) and 3833 middle-aged (mean age 47·9 (sd 4·2) years) Japanese women. Dietary information was collected using a diet history questionnaire. A previously developed diet quality score was computed mainly based on the Japanese Food Guide Spinning Top. The prevalence of depressive symptoms was 22·0 % for young women and 16·8 % for middle-aged women, assessed as a Center for Epidemiologic Studies Depression (CES-D) score ≥23 and ≥19, respectively. As expected, the diet quality score was associated positively with intakes of 'grain dishes', 'vegetable dishes', 'fish and meat dishes', 'milk' and 'fruits' and inversely with intakes of energy from 'snacks, confection and beverages' and Na from seasonings. After adjustment for potential confounders, OR for depressive symptoms in the highest v. lowest quintiles of the diet quality score was 0·65 (95 % CI 0·50, 0·84) in young women (P for trend=0·0005). In middle-aged women, the corresponding value was 0·59 (95 % CI 0·45, 0·78) (P for trend<0·0001). Analyses where the diet quality and CES-D scores were treated as continuous variables also showed inverse associations. In conclusion, this cross-sectional study showed that a higher diet quality score was associated with a lower prevalence of depressive symptoms in young and middle-aged Japanese women. Prospective studies are needed to confirm a public health relevance of this finding.

Background Cigarette smoking is a risk factor of coronary heart disease (CHD). Vascular calcification such as coronary artery calcium (CAC) and aortic calcium (AC) is associated with CHD. We hypothesized that cigarette smoking is associated with coronary artery and aortic calcifications in Japanese and Koreans with high smoking prevalence. Methods Random samples from populations of 313 Japanese and 302 Korean men aged 40 to 49 were examined for calcification of the coronary artery and aorta using electron beam computed tomography. Coronary artery calcium (CAC) and aortic calcium (AC) were quantified using the Agatston score. We examined the associations of cigarette smoking with CAC and AC after adjusting for conventional risk factors and alcohol consumption. Current and past smokers were combined and categorized into two groups using median pack-years as a cutoff point in each of Japanese and Koreans. The never smoker group was used as a reference for the multiple logistic regression analyses. Results The odds ratios of CAC (score ≥10) for smokers with higher pack-years were 2.9 in Japanese (P<0.05) and 1.3 in Koreans (non-significant) compared to never smokers. The odds ratios of AC (score ≥100) for smokers with higher pack-years were 10.4 in Japanese (P<0.05) and 3.6 in Koreans (P<0.05). Conclusion Cigarette smoking with higher pack-years is significantly associated with CAC and AC in Japanese men, while cigarette smoking with higher pack-years is significantly associated with AC but not significantly with CAC in Korean men.

Change in Body Weight Does Not Mediate the Relationship Between Exercise and Smoking Cessation Among Weight-Concerned Women Smokers.

Emery, Rebecca L; Levine, Michele D; Cheng, Yu; Marcus, Marsha D

Exercise has received attention as a method to prevent or reduce postcessation weight gain. However, little is known about how weight changes following quit attempts contribute to the relationship between exercise and smoking cessation. The present study assessed how exercise relates to cessation and whether initial changes in exercise after quitting smoking promote cessation through attenuated weight gain. Weight-concerned women smokers (N = 342) receiving cessation treatment provided biochemical validation of cessation, reported weekly exercise activities, and were weighed at 1, 3, and 6 months following treatment initiation. Survival analyses were used to determine time to and risk of relapse among women who reported engaging in varied levels of exercise at baseline. A mediation analysis was used to examine whether the effect of initial changes in exercise on longer-term cessation was driven by change in weight. All analyses were adjusted for relevant covariates. Women smokers who reported high levels of exercise at baseline were less likely to relapse and returned to smoking more gradually than did women who reported low levels of exercise. Change in weight did not mediate the relationship between exercise and cessation. Cessation interventions utilizing an exercise component may have to develop exercise regimens of either higher duration or greater intensity to produce beneficial cessation outcomes, particularly when targeting sedentary smokers. Given that change in weight did not mediate the relationship between exercise and cessation, it is likely that other mediational processes are involved. © The Author 2014.

The incidence of cervical cancer (CC) is high in Japan and is further increasing among women younger than 30 years. This burden could be reduced by the implementation of a CC vaccine, but its cost-effectiveness is unknown. We quantified the clinical impact and assessed the cost-effectiveness of adding CC vaccination at age 12 to the current screening in place in Japan with a lifetime Markov model adapted to the Japanese setting. Transition probabilities and utility values were obtained from public databases. Direct costs for treatment and screening were estimated using Japanese medical fees. Annual costs and benefits were discounted at 3%. Sensitivity analyses were conducted on the age at vaccination, the vaccine characteristics, the discount rates, the proportion of human papillomavirus types 16/18 in cancer, and the screening coverage. Vaccinating a 12-year-old cohort was predicted to reduce CC incidence and deaths from CC by 73%. These clinical effects were associated with an incremental cost-effectiveness ratio of yen1.8 million per quality-adjusted life year gained. The incremental cost-effectiveness ratio of vaccinating all 10- to 45-year-old women was yen2.8 million per quality-adjusted life year, still below the threshold value. The implementation of a CC vaccination in Japan could reduce the CC burden in a very cost-effective manner for women up to 45 years.

"I Was a Full Time Proper Smoker": A Qualitative Exploration of Smoking in the Home after Childbirth among Women Who Relapse Postpartum.

Many women stop smoking during pregnancy but relapse shortly afterwards, potentially putting their infants at risk of secondhand smoke (SHS) exposure. Women who were able to stop during pregnancy may be a motivated group, receptive to making behaviour changes postpartum to protect their infant from SHS exposure. Understanding more about their experiences of relapse, and if this influences home smoking behaviours and children's exposure to SHS in the home may help to inform intervention development to prevent infant SHS exposure. Guided by interpretative phenomenological methodology we conducted and analysed nine semi-structured interviews with women who quit smoking during pregnancy, but relapsed ≤3 months postpartum. Central to mothers' accounts of their smoking behaviours during pregnancy and postpartum was their desire to be a 'responsible mother'. Mothers described using strategies to protect their infant from SHS exposure, and held strong negative attitudes towards other smoking parents. After relapsing, mothers appeared to reposition themselves as 'social' or 'occasional' smokers rather than 'regular' smokers. Findings suggest that interventions to prevent/reduce infants' home SHS exposure should build on mothers' intentions to be responsible parents. As mothers who relapse principally view themselves as 'social' or 'occasional' smokers, interventions that are highlighted as relevant for women with these types of smoking patterns may be more likely to be responded to, and, ultimately, be effective.

Anthropometrical data of middle-aged Japanese women for industrial design applications.

Despite the growing importance of human interface design, and despite the growing number of working women, no considerations have been given to women's working spaces and tools. Their designs are based on men's anthropometrical data, and this does not assure safety and amenity of women's working environments. Moreover, few data on women's body measurements are available. The Research Institute of Human Engineering for Quality Life is carrying out an ergonomic anthropometrical study on a large number of Japanese people to create a database for industrial use. The fee for the use of these data is, however, making it very difficult to profit from their acquisition. Therefore, we conducted an anthropometrical study for industrial design use on middle-aged female subjects, who are in the most difficult age group to access. This report should be useful in designing working spaces and tools for women as laborers as well as users.

Non-smokers' assertive behaviour towards smokers by asking them not to smoke is important in promoting smoke-free environments. Korean and Chinese Americans come from countries where most women are non-smokers and assertive behaviour may not be prevalent but may increase after migration because of social-ecological factors. This study assessed the extent to which Korean and Chinese American non-smokers ask someone not to smoke and associated factors. The 2003 California Chinese American and Korean American Tobacco Use Surveys were analysed. Multivariate logistic regression analyses examined factors related to non-smoker self-reports that they asked someone not to smoke within the past year. About 40% reported past-year assertive behaviour against smoking, with higher rates among Koreans than Chinese (60.4% vs. 34.5%), those living with smokers (63.5%), ever exposed with a smoke-free home rule (62.3%), recently exposed at work without a smoke-free work policy (67.6%) and regularly exposed at other locations (52.3%). In combined multivariate analyses of both ethnic groups, assertive behaviour was associated with individual factors (single vs. married; tobacco exposure knowledge), family factors (living with smokers, exposed at home despite a smoke-free rule), community factors (exposed at work with no smoke-free policy, exposed at other locations) and cultural factors (Korean vs. Chinese ethnicity; lower acculturation). Chinese and Korean American non-smokers report assertive behaviour against smoking, which is associated with social-ecological factors. Results help identify target groups and strategies for future intervention, including the need to implement or enforce smoke-free environments and promote empowerment.

A non-invasive phenotypic indicator of the rate of nicotine metabolism is nicotine metabolite ratio (NMR) defined as a ratio of two major metabolites of nicotine - trans-3'-hydroxycotinine/cotinine. The rate of nicotine metabolism has important clinical implications for the likelihood of successful quitting with nicotine replacement therapy (NRT). We conducted a study to measure NMR among Polish smokers. In a cross-sectional study of 180 daily cigarette smokers (42% men; average age 34.6±13.0), we collected spot urine samples and measured trans-3'-hydroxycotinine (3-HC) and cotinine levels with LC-MS/MS method. We calculated NMR (molar ratio) and analyzed variations in NMR among groups of smokers. In the whole study group, an average NMR was 4.8 (IQR 3.4-7.3). The group of women below 51 years had significantly greater NMR compared to the rest of the population (6.4; IQR 4.1-8.8 vs. 4.3; IQR 2.8-6.4). No differences were found among group ages of male smokers. This is a first study to describe variations in nicotine metabolism among Polish smokers. Our findings indicate that young women metabolize nicotine faster than the rest of population. This finding is consistent with the known effects of estrogen to induce CYP2A6 activity. Young women may require higher doses of NRT or non-nicotine medications for most effective smoking cessation treatment. Copyright © 2017 Institute of Pharmacology, Polish Academy of Sciences.

Lung cancer in never smokers--a review.

PubMed

Couraud, Sébastien; Zalcman, Gérard; Milleron, Bernard; Morin, Franck; Souquet, Pierre-Jean

2012-06-01

An estimated 10-25% of lung cancers worldwide occur in never smokers, i.e. individuals having smoked less than 100 cigarettes in their lifetime. Lung cancer in never smokers (LCINS) is more frequent in women, although large geographic variations are found. Histologically, adenocarcinomas predominate. The mere existence of LCINS suggests that risk factors other than smoking must be present. Exposure to environmental tobacco smoke (particularly in women) and exposure to workplace carcinogens (particularly in men) are the two most important alternative risk factors. However, a history of either is absent in more than a third of LCINS. The large proportion of women in LCINS suggest a hormonal element that may interact with other identified factors such as hereditary risks, a history of respiratory infections or disease, exposure to air pollution, cooking and heating fumes, or exposure to ionising radiation. The study of genomic polymorphisms finds constitutive DNA variations across subjects according to their smoking status, particularly in genes coding for enzymes that participate in the metabolism of certain carcinogens, in those coding for DNA repair enzymes, or in genes associated with tobacco addiction, or inflammatory processes. The type of molecular mutation in p53 or KRAS varies with smoking status. EGFR mutations are more frequent in never smokers, as are EML4-ALK fusions. The mutually exclusive nature of certain mutations is a strong argument in favour of separate genetic paths to cancer for ever smokers and never smokers. In the present paper we review current clinical and molecular aspects of LCINS. Copyright © 2012 Elsevier Ltd. All rights reserved.

Background: Never smokers comprise a substantial proportion of patients with COPD. Their characteristics and possible risk factors in this population are not yet well defined. Methods: We analyzed data from 14 countries that participated in the international, population-based Burden of Obstructive Lung Disease (BOLD) study. Participants were aged ≥ 40 years and completed postbronchodilator spirometry testing plus questionnaires about respiratory symptoms, health status, and exposure to COPD risk factors. A diagnosis of COPD was based on the postbronchodilator FEV1/FVC ratio, according to current GOLD (Global Initiative for Obstructive Lung Disease) guidelines. In addition to this, the lower limit of normal (LLN) was evaluated as an alternative threshold for the FEV1/FVC ratio. Results: Among 4,291 never smokers, 6.6% met criteria for mild (GOLD stage I) COPD, and 5.6% met criteria for moderate to very severe (GOLD stage II+) COPD. Although never smokers were less likely to have COPD and had less severe COPD than ever smokers, never smokers nonetheless comprised 23.3% (240/1,031) of those classified with GOLD stage II+ COPD. This proportion was similar, 20.5% (171/832), even when the LLN was used as a threshold for the FEV1/FVC ratio. Predictors of COPD in never smokers include age, education, occupational exposure, childhood respiratory diseases, and BMI alterations. Conclusion: This multicenter international study confirms previous evidence that never smokers comprise a substantial proportion of individuals with COPD. Our data suggest that, in addition to increased age, a prior diagnosis of asthma and, among women, lower education levels are associated with an increased risk for COPD among never smokers.

The values of urinary cotinine measured using high performance liquid chromatography in 125 adults (44 men and 81 women) were compared with the degree of intoxication and/or exposure to tobacco experienced over six consecutive days by auto-questionnaire. The subjects were classified in 6 groups: non exposed non smokers and non smokers exposed for less than one hour (1, n = 16); non smokers exposed for between 1 and 10 hours (2, n = 26); non smokers exposed for more than 10 hours and less than 30 hours (3, n = 33); non smokers exposed for more than 30 hours (4, n = 13); smokers smoking less than 20 cigarettes per day (5, n = 16); smokers smoking 20 cigarettes or more per day (6, n = 21). The measurements were made on urine specimens from the first morning (fraction F1), from the day and night (F2) and those of the second morning (F3). The results were expressed in micrograms/fraction and were as follows: Group 1: 37.3 (F1); 149.5 (F2); 26.8 (F3)--Group 2: 81.2; 234.1; 75.4--Group 3: 121.1; 383.1; 80.7--Group 4: 98.8; 253.7; 117.2--Group 5: 206.9; 773.8; 188--Group 6: 483.1; 1908.2; 431.3. Cotinine was found in all individuals whether they declared that they were exposed or non exposed (with the exception of a single person amongs the latter). In spite of a certain amount of overlapping between the results of the individuals in groups 4 and 5, the values obtained enabled a differentiation between the degrees of tobacco absorption.(ABSTRACT TRUNCATED AT 250 WORDS)

Secondhand smoke (SHS) and other air pollutants adversely affect the health of pregnant women and infants. A feasibility study aimed at reducing air pollution in homes of pregnant women or infants living with a smoker was completed. In collaboration with the Baltimore City Health Department, women ≥ 18 years of age and either pregnant nonsmokers, or post-partum (any smoking status) with an infant age 0-12 months were recruited. Homes had at least one smoker. Intervention included two air purifiers and secondhand smoke education. Outcomes included feasibility, change in fine particulate matter (PM 2.5 ), air nicotine, and salivary cotinine pre- and post-intervention. Fifty women were enrolled (mean age 27 years, 92% African American, 71% single, 94% Medicaid eligible, 34% reported smoking) and 86% completed the study. Of the 50 women, 32 had infants and 18 were pregnant at time of enrollment. Post- intervention, 70% of participants reported smokers were less likely to smoke indoors, and 77% had at least one air purifier turned on at the final visit. Participant satisfaction was high (91%) and 98% would recommend air purifiers. Indoor PM 2.5 was significantly decreased (P < 0.001). Salivary cotinine was significantly decreased for non-smoking women (P < 0.01) but not infants, and no significant change in air nicotine occurred (P = 0.6). Air purifiers with SHS education is a feasible intervention in homes of women and infants. These data demonstrate reduction in indoor PM 2.5 and salivary cotinine in non-smoking adults. Air purifiers are not an alternative for smoking cessation and a home/ car smoking ban. Smoking cessation should be strongly encouraged for all pregnant women, and nonsmoking mothers with infants should be counseled to completely avoid SHS exposure. This study provides support for a future intervention evaluating clinical endpoints. Copyright © 2017. Published by Elsevier Inc.

The forced oscillation technique (FOT) can measure respiratory system resistance and reactance under tidal volume respiration. MostGraph is a device that incorporates the FOT and enables the immediate, three-dimensional visualization of resistance and reactance parameters. The aim of this study was to establish MostGraph reference values for middle-aged and elderly Japanese individuals. From 2004 to 2006, 3253 subjects living in Takahata, Yamagata underwent spirometry. Of these, 872 again underwent spirometry in 2011, and 784 (368 men, ages 46-89 years; 416 women, ages 47-90 years) underwent FOT examinations using MostGraph-01. In this study population, 19.0% of the men and 91.5% of the women were life-long never smokers. Abnormal spirometric findings were observed in 30.2% of the men and 14.6% of the women. Although the respiratory system resistance and reactance parameters obtained using MostGraph were not distributed normally, normal distribution was achieved via natural logarithm (R5, R20, Fres, and ALX), square root (R5-R20), or exponential (X5) transformation. Furthermore, the transformed values were converted back to the actual values after determining the values representing one and two standard deviations from the mean. Respiratory system resistance and reactance reference values were determined using MostGraph in middle-aged and elderly Japanese individuals who participated in annual health checkups.

Reaching smokers with lower educational attainment.

PubMed

Millar, W J

1996-01-01

Between 1977 and 1994, smoking rates declined among men and women, but the decline was steeper for men. While smoking rates fell among people at all levels of education, the smallest drop was among those with high school graduation or less, particularly women. For those who had stopped smoking, health concerns had been the overriding factor. Smokers with lower education reported encountering fewer smoking restrictions in their daily activities than did those with higher education. All smokers cited the mass media as their major source of information about smoking, but those with lower education reported the mass media less often than did smokers with higher levels of attainment, and were less likely to obtain information from books, pamphlets or magazines. In addition, smaller percentages of smokers with lower education recalled printed warnings about heart disease on cigarette packages. Variations in the decline of smoking suggest that health promotion and smoking cessation programs should consider sex and educational differences when targeting the smoking population. Differences in rates of smoking among people aged 20 and over were examined by educational attainment using selected health surveys conducted between 1977 and 1994. A Health Canada-sponsored supplement to Statistics Canada's National Population Health Survey was used for data on other aspects of smoking such as cutting back or attempting to quit, sources of health information, and awareness of smoking restrictions and cigarette package warnings.

To identify factors predicting early postpartum glucose intolerance in Japanese women with gestational diabetes mellitus, using decision-curve analysis. A retrospective cohort study was performed. The participants were 123 Japanese women with gestational diabetes who underwent 75-g oral glucose tolerance tests at 8-12 weeks after delivery. They were divided into a glucose intolerance and a normal glucose tolerance group based on postpartum oral glucose tolerance test results. Analysis of the pregnancy oral glucose tolerance test results showed predictive factors for postpartum glucose intolerance. We also evaluated the clinical usefulness of the prediction model based on decision-curve analysis. Of 123 women, 78 (63.4%) had normoglycaemia and 45 (36.6%) had glucose intolerance. Multivariable logistic regression analysis showed insulinogenic index/fasting immunoreactive insulin and summation of glucose levels, assessed during pregnancy oral glucose tolerance tests (total glucose), to be independent risk factors for postpartum glucose intolerance. Evaluating the regression models, the best discrimination (area under the curve 0.725) was obtained using the basic model (i.e. age, family history of diabetes, BMI ≥25 kg/m 2 and use of insulin during pregnancy) plus insulinogenic index/fasting immunoreactive insulin <1.1. Decision-curve analysis showed that combining insulinogenic index/fasting immunoreactive insulin <1.1 with basic clinical information resulted in superior net benefits for prediction of postpartum glucose intolerance. Insulinogenic index/fasting immunoreactive insulin calculated using oral glucose tolerance test results during pregnancy is potentially useful for predicting early postpartum glucose intolerance in Japanese women with gestational diabetes. © 2018 Diabetes UK.

In India, the prevalence of smoking among women is increasing, and the reasons behind this are unclear. We aimed to study the factors leading to initiation and maintenance of the smoking habit in women in Pune, India. Twenty-seven urban women smokers, ranging from 21 to 60 years of age (31.96 ± 10.70 years), were interviewed between September 2015 and February 2016. The in-depth interviews consisted of questions on pre-decided categories, including initiation, motivation to continue smoking, and risk perception. Thematic analysis revealed that peer pressure, curiosity, fascination, experimentation, and belonging to a group were factors that led to initiation, while lack of alternatives for stress relief, work environments, and lack of leisure time activities provided circumstances to continue smoking. Participants recognized a sense of liberation and independence from smoking cigarettes and perceived health risks as minor and distant. These findings can be used to develop or modify interventions to prevent and control smoking among urban Indian women.

The present study assessed food cravings in a cohort of 229 women who differed in smoking history (i.e., never smoker, former smoker, and current smoker) and body weight (i.e., normal weight, overweight, and obese). Each subject completed the Food Craving Inventory (FCI), which measures cravings for sweets, high fats, carbohydrates/starches, and fast-food fats, and the Profile of Mood States (POMS), which measures psychological distress. Smoking and obesity were independently associated with specific food cravings and mood states. Current smokers craved high fats more frequently than former and never smokers. They also craved starches more frequently and felt more depressed and angry than never smokers, but not former smokers. Whereas cravings for starchy foods and some mood states may be characteristic of women who are likely to smoke, more frequent cravings for fat among smokers is related to smoking per se. Similarly, obese women craved high fats more frequently than nonobese women and depression symptoms were intensified with increasing body weights. We hypothesize that the overlapping neuroendocrine alterations associated with obesity and smoking and the remarkable similarities in food cravings and mood states between women who smoke and women who are obese suggest that common biological mechanisms modulate cravings for fat in these women.

Objectives　Our objectives were to conduct a web-based survey using adult participants to investigate 1) differences in attitudes towards smoking in the presence of non-smokers between smokers and non-smokers and 2) the potential impact of knowledge regarding the harmful effects of smoking and secondhand smoke (SHS) on smoker behavior in a restaurant.Method　Japanese smokers and non-smokers aged 20 to 69 were separately sampled and both groups were randomly allocated to either a knowledge group or a control group. The participants were asked to complete an online questionnaire to capture their attitudes and how they think they would behave in a restaurant where it was not clear whether smoking is prohibited or not. Data were analyzed using a t-test for numerical variables and a χ 2 test for categorical variables. Logistic regression analysis was also conducted to elucidate the factors influencing the smoking behavior near non-smokers.Results　Overall, 2,157 participants were surveyed (smokers, n=1,084; non-smokers, n=1,073). Among smokers who intended to smoke in the restaurant, 24.8% answered that they would ask for permission from nearby persons before lighting up. However, only 2.8% of non-smokers had ever actually been asked for such permission. The percentage of smokers who would smoke in the restaurant was significantly lower in the knowledge group (16.4%) than the control group (22.8%). The most common reason for refraining from smoking was a lack of an ashtray on the table in both groups. Among the non-smokers, 37.4% of the knowledge group and 27.6% of the control group answered that they did not like nearby smoking. A multiple logistic regression analysis revealed that smoking in restaurants was significantly associated with nicotine dependence, household income, pregnancy, smoking place in the home, age, and SHS knowledge.Conclusion　This study suggested that most non-smokers do not inform smokers that they do not like nearby smoking.

Many cases of neonatal toxic shock syndrome (TSS)-like exanthematous disease but few cases of menstrual TSS (mTSS) have been reported in Japan. We determined the prevalence of mucosal colonization with Staphylococcus aureus and of positive antibodies to TSS toxin 1 (TSST-1) among 209 healthy Japanese women in Tokyo. S. aureus isolates from mucosal sites were characterized with respect to TSST-1 production and resistance genotype. Antibody titers were determined for test subjects and for 133 Japanese and 137 Caucasian control women living in the United States. S. aureus was isolated from at least one site in 108 of 209 women (52%) in Tokyo. Of the 159 S. aureus isolates recovered, 14 (9%) were TSST-1 positive (12 unique strains). Twelve of 209 women (6%) were colonized with a TSST-1-producing strain; two (<1%) had vaginal colonization. Only 2 of 12 unique toxigenic strains (14%) were methicillin resistant. Of the 12 TSST-1-positive strains isolated, 6 (50%) were pulsed-field gel electrophoresis type USA200, multilocus sequence type clonal complex 30. Fewer Japanese women in Tokyo (47%) than Caucasian and Japanese women in the United States (89% and 75%, respectively) had TSST-1 antibodies. The prevalences of colonization with TSST-1-producing S. aureus were comparable in Japan and the United States, despite low seropositivity to TSST-1 in Japan. Environmental factors appear to be important in promoting the development of anti-TSST-1 antibodies, as there was a significant difference in titers between Japanese women living in Tokyo and those living in the United States. Most colonizing TSST-1-producing S. aureus strains in Japan were genotypically similar to mTSS strains found in the United States.

The Women's Initiative for Nonsmoking (WINS), a randomized clinical trial of a smoking cessation intervention for women with cardiovascular disease, permitted an assessment of the types and costs of health services women used during the 30 months after their hospitalization with cardiovascular disease. A prospective design nested within WINS was used for this study. A structured telephone interview guide included questions about medical services and 15 categories of prevention services, including cardiac rehabilitation at 6, 12, 24, and 30 months. Costs were estimated from state and national databases. The 277 women studied had a mean age of 60.7 +/- 10 years. They had smoked approximately 40 +/- 11.4 years. More than 50% of the women had one or more risk factors for cardiovascular disease. During the first 6 months after the index hospitalization, 94% had a physician visit, 39% had an emergency-room visit, and 36% had a hospital admission. Prevention services used were home healthcare by nurse or home health aide (26%), a cardiac rehabilitation program, including Multifit and Heart Smart (19%), and physical therapy (14%). Usage decreased over the 30 months. For the women who used any service, the mean total monthly cost per woman was 913 dollars +/- 1204 dollars. This is the first report on health service use by women smokers with cardiovascular disease. Data collection using a telephone interview guide proved feasible for evaluating health service use. The greatest costs resulted from hospital admissions and physician and emergency-room visits. Considering the high prevalence of risk factors in this cohort, secondary prevention services were severely underutilized. By increasing referrals to such services, physicians and nurses might influence women to reduce their risk for subsequent cardiovascular disease.

According to the recent 2015 Nutrition Survey, the prevalence of being underweight (Body Mass Index, BMI <18.5 kg/m 2 ) among women in their 20s is 22.3%. Women of childbearing age tend to have a lower intake of protein and their total energy intake is lower than the requirements established by the 2015 Dietary Reference Intakes for Japanese. There is a growing body of evidence showing that underweight women tend to bear small babies and that these babies have an increased risk of diabetes or cancer in their adulthood. In order to prevent Japanese women from bearing small babies, the literature has suggested that women of childbearing age should be encouraged to remain at a normal weight before pregnancy. For optimal weight gain during pregnancy, existing guidelines recommend different ranges of weight gain based on prepregnancy BMI. Owing to the absence of official GWG recommendations in Asian countries, including China and Taiwan, the US Institute of Medicine (IOM) guidelines are generally followed. However, Asian women are smaller and experience lower weight gains; therefore, excessive weight gain may lead to harmful events including macrosomia, preterm birth, preeclampsia, gestational diabetes, pregnancy-induced hypertension, and short- and long-term postpartum weight retention. Thus, an accurate GWG range should be determined for Asian women. We introduce one epidemiological study in which the optimal weight gain range was investigated by analyzing receiver-operating characteristic curves together with potential research ideas in this field with the aim of encouraging young researchers to solve this public health problem affecting mothers and children.

This study assessed whether pregnancy-induced hypertension (PIH) affects the prevalence of cardiovascular disease (CVD) risk factors in later life among Japanese women. Study participants were 1,185 women (mean [SD] age, 46.5 [5.6] y; range, 38-73 y) aged 40 years or older who underwent a health checkup at a periodic health examination facility between January 2012 and December 2013 and had experienced giving birth. Questionnaires were sent to potential participants, and they were encouraged to provide their Maternal and Child Health Handbook (handbook). We recruited 101 women with a history of PIH (PIH group) and 1,084 women with uncomplicated pregnancy at delivery (control group). Groupings were based on information from the handbook. We assessed the association between PIH and CVD in later life among Japanese women by focusing on hypertension, diabetes mellitus, and dyslipidemia as risk factors for CVD. Odds ratios (ORs) for the use of antihypertensive, diabetes mellitus, and dyslipidemic medications in the PIH group were determined. Women with PIH had increased risk of antihypertensive medication use compared with women without PIH (2.9% vs 13.9%; OR, 4.28; 95% CI, 2.14-8.57). Triglycerides were significantly higher and high-density lipoprotein cholesterol was significantly lower in the PIH group than in the control group. The OR for dyslipidemic medication use in the PIH group relative to the control group was 3.20 (95% CI, 1.42-7.22). Our findings suggest that a history of PIH may be associated with an increased risk of hypertension (a risk factor for CVD) in later life among Japanese women.

Cigarette smoking is one of the most common habits of the modern world. According to a NATPOL PLU study, every third adult Pole is dependent on nicotine. Tobacco smoke contains about 5,000 components, of which over 1,000 are very toxic chemical substances (3,4-benzopyrene, heavy metals, free radicals, hydrogen cyanide, nitrogen oxides and N-nitrosamines). Exposure to tobacco smoke is an example of a complex, with a significant number of interactions. To assess the concentration of copper in the urine of smokers. Based on the results, an attempt was made to determine whether smoking can affect the level of copper in the body. The study involved 170 healthy volunteers, 99 smokers and 71 non-smokers (control group). The age of patients in both groups were in the range of 20-60 years. The mean age for men and women was 41 years. The average length of cigarette smoking was 18 years for women and 21 years for men, and the number of cigarettes smoked 1-40 ⁄ 24. The urine concentrations of Cu were determined by atomic absorption spectrometry (AAS) and serum creatinine kinetic method using a set of BIOLAB. Cu concentration in urine was expressed in mg / g creatinine. Smokers were found to have reduced levels of copper in the urine, depending on sex, age and brand of cigarettes. In male smokers, copper concentration in the urine was dependent on age and time of smoking, whereas among women this relationship was not observed. Cigarette smoking significantly influences the level of copper in the urine. Both female and male smokers showed reduced levels of copper in the urine, which may indicate its increased accumulation in the body. Excessive accumulation of copper is very dangerous since it may exhibit toxic effects towards many organs and systems.

Increasing evidence suggests that osteocalcin is involved in the regulation of glucose homeostasis. However, the relationship between serum osteocalcin levels and risk of incident type 2 diabetes mellitus is not clear. The objective of this study is to investigate whether serum osteocalcin levels are associated with the risk of incident type 2 diabetes mellitus. This study included 1691 Japanese postmenopausal women, 61 incident diabetes cases, and 1630 non-diabetic control subjects in the observation period. Baseline concentrations of intact osteocalcin, HbA1c, bone-specific alkaline phosphatase, adiponectin, leptin, urinary N-telopeptides were assessed. Serum osteocalcin levels were significantly correlated with HbA1c levels among 1691 Japanese postmenopausal women (R = -0.12, P < 0.0001). In receiver operating characteristic curve analysis, the optimal cut-off levels for serum osteocalcin to predict the development of type 2 diabetes mellitus was 6.1 ng/mL. The group with baseline osteocalcin levels <6.1 ng/mL showed a significantly higher risk for developing diabetes than the group with baseline osteocalcin levels >6.1 ng/mL (log-rank test, P  <  0.0001) during the mean observation period (7.6 ± 6.1 years; mean ± SD). In multiple Cox proportional hazard analysis, osteocalcin levels were significantly associated with development of type 2 diabetes mellitus during the observation period. Our results indicate that a decrease in serum osteocalcin levels is associated with future development of type 2 diabetes mellitus independent of conventional risk factors in Japanese postmenopausal women.

Reactivity to smoking- and food-related cues in currently dieting and non-dieting young women smokers.

There is some evidence to suggest that young women dieters who smoke experience greater cigarette cravings in the presence of food-related related cues. The aim of this experiment was to examine reactivity to both smoking-related and water cues by dieting and non-dieting women smokers in the presence or absence of food cues. Eighteen female undergraduates attended two sessions (food present and food absent). At each session, participants were presented with a cigarette and water cue in a counterbalanced order. Pre- and post-cue measures included the brief version of the Questionnaire for Smoking Urges, heart rate and self-reported mood. All smokers showed enhanced reactivity (increased craving and heart rate) to smoking versus water cues. For dieters there was a larger increase in cigarette craving and heart rate in response to the smoking-related cues in the presence of food compared with the absence of food, whereas for non-dieters there was a smaller increase in cigarette craving and heart rate in response to the smoking-related cues in the presence of food compared with the absence of food. Mood and appetite ratings were not significantly affected by either cue type or session. The results suggest that cue reactivity to smoking-related cues is modulated by the presence of incentive stimuli relevant to the individual.

Chronic obstructive pulmonary disease (COPD) mainly develops after long-term exposure to cigarette or biomass fuel smoke, but also occurs in non-smokers with or without a history of asthma. We investigated the proportion and clinical characteristics of non-smokers among middle-aged to elderly subjects with airflow obstruction. We retrospectively analyzed 1,892 subjects aged 40-89 years who underwent routine preoperative spirometry at a tertiary university hospital in Japan. Airflow obstruction was defined as a forced expiratory volume in 1 second (FEV1)/forced vital capacity < 0.7 or as the lower limit of the normal. Among 323 patients presenting with FEV1/forced vital capacity < 0.7, 43 had asthma and 280 did not. Among the non-asthmatic patients with airflow obstruction, 94 (34%) were non-smokers. A larger number of women than men with airflow obstruction had asthma (26% vs. 7.6%, p < 0.001), or were non-smokers among non-asthmatics (72% vs. 20%, p < 0.001). Non-asthmatic non-smokers, rather than non-asthmatic smokers, asthmatic non-smokers, and asthmatic smokers, exhibited better pulmonary function (median FEV1: 79% of predicted FEV1 vs. 73%, 69%, and 66%, respectively, p = 0.005) and less dyspnea on exertion (1% vs. 12%, 12%, and 28%, respectively, p = 0.001). Pulmonary emphysema on thoracic computed tomography was less common in non-smokers (p < 0.001). Using the lower limit of the normal to define airflow obstruction yielded similar results. There are a substantial number of non-smokers with airflow obstruction compatible with COPD in Japan. In this study, airflow obstruction in non-smokers was more common in women and likelier to result in mild functional and pathological abnormalities than in smokers. Further studies are warranted to investigate the long-term prognosis and appropriate management of this population in developed countries, especially in women.

Posttraumatic stress disorder (PTSD) has been associated with cognitive impairments, yet little is documented on the cognitive function of PTSD patients in Asian countries. It is shown that regular exercise can reduce PTSD symptoms, while no study has investigated the association between exercise and cognition in PTSD patients. This study aimed to examine cognitive functions of Japanese women with PTSD, and to explore the association between regular exercise and cognitive functions. Forty-two women with DSM-IV PTSD and 66 demographically matched healthy control women participated in this study. Most of the patients developed PTSD after experiencing interpersonal violence. Cognitive functions were assessed by the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). Regular exercise habit was assessed by a self-reported questionnaire. Compared to controls, PTSD patients performed significantly more poorly in all cognitive domains examined, including immediate memory, visuospatial construction, language, attention, delayed memory, as well as the total score of RBANS (all p < 0.001). Compared to PTSD patients without the habit of exercise, those who habitually exercised showed significantly better performance on delayed memory (p = 0.006), which survived after controlling for potentially confounding variables in a multiple regression model. The cross-sectional design and relatively small sample size limited our findings. PTSD in Japanese women is associated with pervasively impaired cognitive functions, including notable impairments in verbal memory. Such memory deficits might be improved by regular exercise, although further studies are needed to investigate the causal relationship between exercise and cognition in PTSD.

We prospectively examined the association between coffee consumption and the risk of developing colorectal cancer in a large population-based cohort study (the JPHC Study) of Japanese men and women. Data were analyzed from a population-based cohort of 96,162 subjects (46,023 men and 50,139 women). A total of 1,163 incident colorectal cancers were identified during the follow-up period, including 763 cases of colon cancer and 400 of rectal cancer. We observed a significant inverse association between coffee consumption and the risk of developing invasive colon cancer among women. Compared with those who almost never consumed coffee, women who regularly consumed 3 or more cups of coffee per day had a RR of 0.44 (95% CI = 0.19-1.04; p for trend = 0.04) after adjustment for potential confounding factors. However, no significant association was found for rectal cancer in women. In men, no significant decrease was observed in any colorectal cancer site. Further, additional analyses on the association of green tea consumption with colorectal cancer risk found no significant association in men or women. These findings suggest that coffee consumption may lower the risk of colon cancer among Japanese women. (c) 2007 Wiley-Liss, Inc.

1) To obtain insight into pregnant smokers' experience of the information received from doctor and midwife at the ante-natal clinic. 2) To develop an understanding of pregnant women's own ideas of how health personnel can help them stop smoking. Qualitative study with strategic sampling. 33 pregnant smokers took part in an in-depth interview in the third trimester. Home of patients, or surgeries in Hordaland county, Norway. Daily smokers during the last three months before conception, and still smoking in the 16th-18th week of pregnancy. Pregnant women lacking motivation to stop smoking seemed to be most satisfied with ante-natal care. The women interviewed saw doctors and midwives as responsible for raising the subject of smoking, and blamed them for disinterest. The findings suggest that pregnant smokers may be classified into four categories ("it could have been worse", "self-delusion", "self-confident", and "rational"), and that intervention should be tailored to meet each woman's perception of control over smoking behaviour.

There is limited data on the risk factors and phenotypical characteristics associated with spirometrically confirmed COPD in never-smokers in the general population. To compare the characteristics associated with COPD by gender and by severity of airway obstruction in never-smokers and in ever-smokers. We analysed the data from 5176 adults aged 40 years and older who participated in the initial cross-sectional phase of the population-based, prospective, multisite Canadian Cohort of Obstructive Lung Disease study. Never-smokers were defined as those with a lifetime exposure of <1/20 pack year. Logistic regressions were constructed to evaluate associations for 'mild' and 'moderate-severe' COPD defined by FEV1/FVC <5th centile (lower limits of normal). Analyses were performed using SAS V.9.1 (SAS Institute, Cary, North Carolina, USA). The prevalence of COPD (FEV1/FVCsmokers was 6.4%, constituting 27% of all COPD subjects. The common independent predictors of COPD in never-smokers and ever-smokers were older age, self reported asthma and lower education. In never-smokers a history of hospitalisation in childhood for respiratory illness was discriminative, while exposure to passive smoke and biomass fuel for heating were discriminative for women. COPD in never-smokers and ever-smokers was characterised by increased respiratory symptoms, 'respiratory exacerbation' events and increased residual volume/total lung capacity, but only smokers had reduced DLCO/Va and emphysema on chest CT scans. The study confirmed the substantial burden of COPD among never-smokers, defined the common and gender-specific risk factors for COPD in never-smokers and provided early insight into potential phenotypical differences in COPD between lifelong never-smokers and ever-smokers.

To systematically review the literature describing the efficacy, effectiveness, and safety of raloxifene for postmenopausal Japanese women with osteoporosis or low bone mass (osteopenia). Medline via PubMed and Embase was systematically searched using prespecified terms. Retrieved publications were screened and included if they described randomized controlled trials or observational studies of postmenopausal Japanese women with osteoporosis or osteopenia treated with raloxifene and reported one or more outcome measures (change in bone mineral density [BMD]; fracture incidence; change in bone-turnover markers, hip structural geometry, or blood-lipid profile; occurrence of adverse events; and change in quality of life or pain). Excluded publications were case studies, editorials, letters to the editor, narrative reviews, or publications from non-peer-reviewed journals; multidrug, multicountry, or multidisease studies with no drug-, country-, or disease-level analysis; or studies of participants on dialysis. Of the 292 publications retrieved, 15 publications (seven randomized controlled trials, eight observational studies) were included for review. Overall findings were statistically significant increases in BMD of the lumbar spine (nine publications), but not the hip region (eight publications), a low incidence of vertebral fracture (three publications), decreases in markers of bone turnover (eleven publications), improved hip structural geometry (two publications), improved blood-lipid profiles (five publications), a low incidence of hot flushes, leg cramps, venous thromboembolism, and stroke (12 publications), and improved quality of life and pain relief (one publication). Findings support raloxifene for reducing vertebral fracture risk by improving BMD and reducing bone turnover in postmenopausal Japanese women with osteoporosis or osteopenia. Careful consideration of fracture risk and the risk-benefit profile of antiosteoporosis medications is required when

Background A number of studies have documented the influence of cigarette smoking on hearing. However, the association between sex and hearing impairment in smokers as measured by otoacoustic emissions (OAEs) has not been clearly established. The aim of this study was to analyze sex-specific effects of smoking on hearing via conventional and ultra-high-frequency pure tone audiometry (PTA), and OAEs, specifically spontaneous OAEs, click-evoked OAEs, and distortion-product OAEs. Material/Methods The study included 84 healthy volunteers aged 25–45 years (mean 34), among them 46 women (25 non-smokers and 21 smokers) and 38 men (16 non-smokers and 22 smokers). The protocol of the study included otoscopic examination, tympanometry, low-, moderate-, and ultra-high-frequency PTA, evaluation of spontaneous click-evoked (CEAOEs) and distortion-product otoacoustic emissions (DPOAEs), assessment of the DP-grams for 2f1-f2 (f1 from 977 to5 164 Hz), and input/output function at L2 primary tone level of 40–70 dB SPL. Results Smokers and non-smokers did not differ significantly in terms of their hearing thresholds assessed with tone audiometry. Male smokers presented with significantly lower levels of CEAOEs and DPOAEs than both male non-smokers and female smokers. Conclusions Smoking does not modulate a hearing threshold determined with PTA at low, moderate, and ultra-high frequencies, but causes a significant decrease in OAE levels. This effect was observed only in males, which implies that they are more susceptible to smoking-induced hearing impairment. Sex-specific differences in otoacoustic emissions level may reflect influences of genetic, hormonal, behavioral, and/or environmental factors. PMID:28110343

Solar lentigines are common acquired pigmented lesions on sun-exposed skin. Their histopathological features have been reported as large numbers of melanocytes at the base of clubbed and budding rete ridges. In this study, biopsies were taken from facial solar lentigines in 40 Japanese women, and the sections were stained using hematoxylin-eosin, Fontana-Masson, and immunostained for melanocytes and Langerhans cells in order to verify the histological patterns of Japanese patients. We characterized the histopathological features of solar lentigines on the face and identified two patterns: one pattern (20/40 cases) demonstrated a flattened epidermis with basal melanosis, and the other pattern (20/40 cases) showed epidermal hyperplasia with elongated rete ridges composed of deeply pigmented basaloid cells. We termed the former pattern the "flattened epidermis" group, and the latter the "budding" group, respectively. The flattened epidermis group showed a significantly thinner epidermis, more severe solar elastosis and fewer Langerhans cells in the epidermis as compared with the budding group. We concluded that more severely sun-damaged solar lentigines might show the changes observed in the flattened epidermis group. Langerhans cells in the epidermis of solar lentigines might play a role in the remission of postinflammatory pigmentation due to aesthetic treatment. © 2012 Japanese Dermatological Association.

Background and objectives Chronic obstructive pulmonary disease (COPD) mainly develops after long-term exposure to cigarette or biomass fuel smoke, but also occurs in non-smokers with or without a history of asthma. We investigated the proportion and clinical characteristics of non-smokers among middle-aged to elderly subjects with airflow obstruction. Methods We retrospectively analyzed 1,892 subjects aged 40–89 years who underwent routine preoperative spirometry at a tertiary university hospital in Japan. Airflow obstruction was defined as a forced expiratory volume in 1 second (FEV1)/forced vital capacity < 0.7 or as the lower limit of the normal. Results Among 323 patients presenting with FEV1/forced vital capacity < 0.7, 43 had asthma and 280 did not. Among the non-asthmatic patients with airflow obstruction, 94 (34%) were non-smokers. A larger number of women than men with airflow obstruction had asthma (26% vs. 7.6%, p < 0.001), or were non-smokers among non-asthmatics (72% vs. 20%, p < 0.001). Non-asthmatic non-smokers, rather than non-asthmatic smokers, asthmatic non-smokers, and asthmatic smokers, exhibited better pulmonary function (median FEV1: 79% of predicted FEV1 vs. 73%, 69%, and 66%, respectively, p = 0.005) and less dyspnea on exertion (1% vs. 12%, 12%, and 28%, respectively, p = 0.001). Pulmonary emphysema on thoracic computed tomography was less common in non-smokers (p < 0.001). Using the lower limit of the normal to define airflow obstruction yielded similar results. Conclusions There are a substantial number of non-smokers with airflow obstruction compatible with COPD in Japan. In this study, airflow obstruction in non-smokers was more common in women and likelier to result in mild functional and pathological abnormalities than in smokers. Further studies are warranted to investigate the long-term prognosis and appropriate management of this population in developed countries, especially in women. PMID:29742176

Self-reported use of cigarettes generally underestimates the true cigarette exposure of smokers. Serum cotinine is considered the best biomarker to evaluate tobacco exposure. This study determined whether or not there were any significant differences in serum cotinine concentrations between men and women when they reported smoking the same number of cigarettes per day. We analyzed cotinine and tobacco consumption data on 680 women and 840 men, aged 20 years or older, who smoked at least 100 cigarettes during their lifetime and were still actively smoking at the time of the National Health and Nutrition Examination Surveys (1999-2002). Overall, compared with men, women reported smoking fewer cigarettes per day (16.1 vs. 18.7, p<.001) and had lower serum cotinine concentrations (1163.3 nmol/L vs. 1343.9 nmol/L, p<.001). Women were more likely than men to smoke filtered (p = .018) and mentholated (p<.001) cigarettes. After adjustment for the number of cigarettes smoked per day, age, race, body mass index, poverty status, the use of either menthol or regular cigarettes, and the nicotine content in cigarettes, female compared with male smokers had lower serum cotinine concentrations (difference of 117.6 nmol/L; 95% CI = 42.6-192.6, p = .003). The difference was particularly notable in moderate to heavy smokers (i.e., those who smoked more than 15 cigarettes/day). These findings indicate that significant sex-related differences exist in serum cotinine levels among smokers, which suggests that self-reports may overestimate cigarette exposure in women compared with men.

Despite being highly educated in comparison with women in other member countries of the Organisation for Economic Cooperation and Development, Japanese women are expected to assume traditional gender roles, and many dedicate themselves to full-time housewifery. Women working outside the home do so under poor conditions, and their health may not be better than that of housewives. This study compared the self-rated health status and health behaviours of housewives and working women in Japan. Cross-sectional survey. A national university in Tokyo with 9864 alumnae. A total 1344 women who graduated since 1985 and completed questionnaires in an anonymous mail-based survey. Health anxiety and satisfaction, receipt of health check-ups, eating breakfast, smoking, and sleep problems according to job status and family demands: housewives (n=247) and working women with (n=624) and without (n=436) family demands. ORs were used for risk assessment, with housewives as a reference. After adjustment for satisfaction with present employment status and other confounding factors, working women were more likely than housewives to feel health anxiety (with family demands, OR: 1.68, 95% CI1.10 to 2.57; without family demands, OR: 3.57, 95% CI 2.19 to 4.50) and health dissatisfaction (without family demands, OR: 3.50, 95% CI 2.35 to 5.21); they were also more likely than housewives to eat an insufficient breakfast (with family demands, OR: 1.91, 95% CI 1.22 to 3.00; without family demands, OR: 4.02, 95% CI 2.47 to 6.57) and to have sleep problems (ORs: 2.08 to 4.03). No healthy-worker effect was found among Japanese women. Housewives, at least those who are well educated, appear to have better health status and health-related behaviours than do working women with the same level of education.

There are limited data on, and controversies regarding gender differences in the airway dimensions of smokers. Multi-detector CT (MDCT) images were analyzed to examine whether gender could explain differences in airway dimensions of anatomically matched airways in smokers. We used VIDA imaging software to analyze MDCT scans from 2047 smokers (M:F, 1021:1026) from the COPDGene® cohort. The airway dimensions were analyzed from segmental to subsubsegmental bronchi. We compared the differences of luminal area, inner diameter, wall thickness, wall area percentage (WA%) for each airway between men and women, and multiple linear regression including covariates (age, gender, body sizes, and other relevant confounding factors) was used to determine the predictors of each airway dimensions. Lumen area, internal diameter and wall thickness were smaller for women than men in all measured airway (18.4 vs 22.5 mm(2) for segmental bronchial lumen area, 10.4 vs 12.5 mm(2) for subsegmental bronchi, 6.5 vs 7.7 mm(2) for subsubsegmental bronchi, respectively p < 0.001). However, women had greater WA% in subsegmental and subsubsegmental bronchi. In multivariate regression, gender remained one of the most significant predictors of WA%, lumen area, inner diameter and wall thickness. Women smokers have higher WA%, but lower luminal area, internal diameter and airway thickness in anatomically matched airways as measured by CT scan than do male smokers. This difference may explain, in part, gender differences in the prevalence of COPD and airflow limitation.

Smoking-related respiratory diseases are a major cause of morbidity and mortality. However, the relationship between smoking and respiratory disease has not been well-studied among ethnic minorities in general and among women in particular. The objective of this cross-sectional study was to evaluate the risk of airflow obstruction and to assess lung function among Hispanic and non-Hispanic White (NHW) female smokers in a New Mexico cohort. Participants completed a questionnaire detailing smoking history and underwent spirometry testing. Outcomes studied included airflow obstruction, selected lung function parameters, and chronic mucus hyper-secretion. Chi square, logistic, and linear regression techniques were utilized. Of the 1,433 eligible women participants, 248 (17.3%) were Hispanic; and 319 had airflow obstruction (22.3%). Hispanic smokers were more likely to be current smokers, and report lower pack-years of smoking, compared to NHW smokers (p < 0.05 for all analyses). Further, Hispanic smokers were at a reduced risk of airflow obstruction compared to NHW smokers, with an O.R. of 0.51, 95% C.I. 0.34, 0.78 (p = 0.002) after adjustment for age, BMI, pack-years and duration of smoking, and current smoking status. Following adjustment for covariates, Hispanic smokers also had a higher mean absolute and percent predicted post-bronchodilator FEV(1)/FVC ratio, as well as higher mean percent predicted FEV(1) (p < 0.05 for all analyses). Hispanic female smokers in this New Mexico-based cohort had lower risk of airflow obstruction and better lung function than NHW female smokers. Further, smoking history did not completely explain these associations.

Many studies have found a significantly lower frequency of reported hot flashes (HFs) in Japanese and Japanese American (JA) populations, leading to speculation about possible dietary, genetic, or cultural differences. These studies have relied on subjective reports of HFs. Accordingly, the purpose of this study was to compare both reported and objective HFs measured by sternal and nuchal skin conductance among JA and European American (EA) women. Two surveys of HF frequencies were carried out among women of either EA or JA ethnicity; aged 45 to 55 years; living in Hilo, Hawaii; and not using exogenous hormones. The first was a postal questionnaire (n = 325); the second was carried out during a clinical study of HFs (n = 134). Women in the second group underwent 24-hour ambulatory and 3-hour laboratory monitoring for objective HFs measured through skin conductance at sternal and nuchal sites. Subjective HFs were recorded on the monitor or in a diary. JAs were significantly less likely to report having had HFs in the previous 2 weeks compared with EAs (postal sample: JAs, 30.9%; EAs, 43.9%; chi(2) = 6.9, P < 0.01; monitored sample: JAs, 26.1%; EAs, 46.6%; chi(2) = 5.3, P < 0.05). JAs were also significantly less likely to report experiencing other symptoms (15 of 30 in the postal sample; 6 of 30 in the monitored sample) than EAs. However, JAs did not significantly differ in likelihood of reporting subjective HFs during the 24-hour ambulatory period (JAs, 51.1%; EAs, 55.8%; chi(2) = 0.3, NS), nor in percentage of individuals displaying one or more objective HFs as measured by the skin conductance monitor (JAs, 77.8%; EAs, 72.1%; chi(2) = 0.5, NS). JAs also did not have a significantly fewer number of objective HFs (t = 0.2, NS) nor of subjective HFs (t = 0.8, NS) during the monitoring period, and these results were unchanged when analyses controlled for menopause status and body mass index.

Lessons on aging: Hopes and concerns of Japanese women at midlife.

Melby, Melissa K

2016-01-01

Japan is leading the global trend of decreasing birth rates and the graying of society. In this study we examine women's changing gender and intergenerational relationships and how these affect their concerns and hopes for their futures. Many of the 121 midlife women (aged 45-55) interviewed viewed themselves as sandwiched between their mothers-in-law and actual or potential daughters-in-law, at the nadir of intergenerational status within their families, in large part due to changing social patterns in marriage and birth rates. Doubts about the marriageability of their sons arising from role expectations for brides to care for parents-in-law cause concern for many and highlight the gendered and intergenerational nature of aging concerns. Yet, midlife in the 21st century, with changing gender and intergenerational roles, appears to create opportunities for many Japanese women to reflect on the meaning of the next stage of their lives. Changing gender and intergenerational relationships may contribute to their hopes to live a life of self-actualization and to be true to one's self (jibun rashiku ikiru).

Several studies have reported inconsistent results regarding the association between the PPARγPro12Ala polymorphism and obesity. Obese individuals had higher C-reactive protein (CRP) levels compared with those of normal weight, and PPARγ activation could significantly reduce serum high-sensitive CRP level. We have previously suggested that the Pro12Ala polymorphism represents a susceptibility factor for periodontitis, which is a known risk factor for increased CRP level. The aim was to investigate associations between PPARγ gene polymorphism, serum CRP level, BMI and/or periodontitis among post-menopausal Japanese women. The final sample in this study comprised 359 post-menopausal Japanese women. Periodontal parameters, including PD, CAL and BOP, were measured per tooth. PPARγPro12Ala genotype was determined by PCR-RFLP. Hs-CRP value was measured by a latex nephelometry assay. No significant differences in age, BMI or periodontal parameters were found between the genotypes. The percentages of sites with PD ≥ 4 mm were significantly higher among the hsCRP ≥ 1 mg/l group than the hsCRP < 1 mg/l group (p = 0.003). Positive correlations were found between serum hsCRP levels and the percentages of sites with PD ≥ 4 mm (p = 0.043) in PPARγ Ala allele carriers, and BMI (p = 0.033) in non-carriers. After adjustment for model covariates, BMI was significantly associated with serum hsCRP level. The PPARγPro12Ala polymorphism was not independently associated with periodontitis, serum CRP level or BMI in post-menopausal Japanese women.

To determine the diagnostic potential of plasma lipids and apolipoproteins in gestational diabetes mellitus (GDM), we carried out a retrospective cohort study of 1,161 Japanese women at 20-28 weeks of gestation who underwent a glucose challenge test (GCT). A total of 1,161 Japanese women at 20-28 weeks of gestation underwent a GCT. Participants with a positive test (GCT[+]) underwent a subsequent oral glucose tolerance test. Clinical and biochemical parameters were determined and quantification of apolipoproteins (Apo), including ApoB, ApoB48, ApoA-I and ApoC-III, was carried out. The prevalence of GCT(+; with a 130 mg/dL glucose cut-off) and GDM was 20% and 4%, respectively. There was a trend for increased triglycerides and ApoC-III in GDM(+) participants. However, the difference in plasma triglycerides, ApoC-III or ApoB48 did not reach statistical significance between GDM(+) and GDM(-) women. Values of 1-h glucose (P < 0.001) and fasting glucose (P = 0.002) were significant risk factors for GDM. Prediction of GDM using only the ApoC-III value is not easy, although triglycerides and ApoC-III were higher in the GDM(+) group. The present findings show no significant difference in plasma lipid levels between women diagnosed with GDM and those with normal glucose tolerance.

Carboxyhaemoglobin concentrations were measured in 3487 subjects comprising 1255 non-smokers, 1933 cigarette smokers, 193 cigar smokers (39 primary, 154 secondary), and 106 pipe smokers (30 primary, 76 secondary). In cigarette smokers the mean carboxyhaemoglobin concentration was 4.78% of the total haemoglobin and 94.7% of smokers had a concentration greater than 1.7%. Primary cigar smokers had a much lower mean carboxyhaemoglobin concentration (0.93%), and only 10.3% had concentrations greater than 1.7%. Primary pipe smokers also had a low mean carboxyhaemoglobin concentration (1.36%) and none had a concentration above 1.7%. Secondary cigar smokers had a high mean concentration (6.80%) and 97.4% had values above 1.7%; the findings in secondary pipe smokers were similar--the mean concentration was 3.39%, 94.7% having values greater than 1.7%. The lower carboxyhaemoglobin concentrations in primary pipe and cigar smokers suggest that in general they do not inhale, and the raised concentrations in cigarette smokers who change to pipes or cigars suggest that they usually continue to inhale and to absorb large amounts of carbon monoxide and other constituents of tobacco smoke.

Stigma and hostility towards pregnant smokers: does individuating information reduce the effect?

PubMed

Wigginton, Britta; Lee, Christina

2013-01-01

Australia is at the forefront of tobacco control, yet 17% of Australian women smoke during pregnancy. Negative attitudes to smoking are intensified when the smoker is pregnant, consistent with a discourse that encourages surveillance of pregnant women. Such overt anti-smoking attitudes create a context which may make it difficult for pregnant smokers to seek assistance to stop. However, there is little evidence on the extent to which pregnant smokers are stigmatised by community members. We used vignettes to examine the degree of smoking-related stigma expressed by 595 Australian university students who rated a woman, described as a mother who was smoking or not, and pregnant or not. Further, we examined whether provision of individuating information reduced the degree of stigma. Mothers described as smokers were rated more negatively than those not, particularly if they were pregnant: smokers were perceived as unhealthy, and also as bad mothers. Provision of individuating information slightly reduced these effects. These findings support the view that smokers--particularly if pregnant--are subject to negative moral judgement. Our findings contribute to the ethical debate about stigma-inducing tobacco control efforts, and suggest that anti-smoking campaigns that contextualise smoking in pregnancy might reduce stigma and assist cessation.

Isoflavone intake has been associated with a reduction in the risk of cardiovascular disease in postmenopausal women. The aim of the present study was to determine if the effects of isoflavones on vascular function differ between premenopausal and postmenopausal women and between women who smoke and those who do not. Women smokers and nonsmokers who consumed 50 mg of isoflavone/day as black soybean tea for a period of 2 months (n = 55, mean age 39) were enrolled in the present study. We examined endothelial function, which was assessed by the percent change in flow-mediated dilation (%FMD) and arterial wall stiffness using the cardio-ankle vascular index (CAVI), as well as by biochemical parameters of the blood. Neither premenopausal (p = 0.697) nor postmenopausal (p = 0.389) smokers experienced an increase in %FMD after daily consumption of isoflavones. However, both premenopausal (p = 0.004) and postmenopausal (p = 0.019) nonsmokers exhibited a marked elevation in %FMD. By contrast, isoflavone intake effectively reduced CAVI among both premenopausal smokers (p = 0.027) and nonsmokers (p = 0.013), but had no effect on CAVI among postmenopausal smokers (p = 0.169) or nonsmokers (p = 0.128). The women smokers and nonsmokers did not differ in age or %FMD at the time of enrollment in the study. Thus, isoflavones have different effects on vascular endothelial function and arterial wall stiffness in premenopausal and postmenopausal smokers and nonsmokers.

Lifestyle-related chronic diseases such as cancer and cardiovascular disease are the greatest public health concerns. Evidence shows Japanese immigrants to a westernized environment have higher incidence of lifestyle-related diseases. However, little is known about lifestyle characteristics related to chronic diseases for Japanese in a westernized environment. This study is examining the gap in lifestyle by comparing the lifestyle prevalence for Japanese in the US with the Japanese National Data (the National Health and Nutrition Survey in Japan, J-NHANS) as well as the Japan National Health Promotion in the twenty-first Century (HJ21) goals. Japanese adults were surveyed in Pittsburgh, USA, regarding their lifestyle (e.g., diet, exercise, smoking, stress, alcohol, and oral hygiene). The prevalence was compared with J-NHANS and HJ21 goals. Ninety-three responded (response rate; 97.9%). Japanese men (n = 38) and women (n = 55) in Pittsburgh smoke less than Japanese in Japan (P < 0.001 for both genders). Japanese in Pittsburgh perform less physical activity in daily life and have lower prevalence of walking more than 1 h per day (P < 0.001 for both genders). Japanese women in Pittsburgh have significantly higher prevalence of stress than in Japan (P = 0.004). Japanese men in Pittsburgh do not reach HJ21 goal in weight management, BMI, use of medicine or alcohol to sleep, and sleep quality. Japanese women in Pittsburgh do not reach HJ21 goal in weight management and sleep quality. In conclusion, healthy lifestyle promotion including exercise and physical activity intervention for Japanese living in a westernized environment is warranted.

Adenocarcinoma (AC) has become the most frequent type of lung cancer in men and women, and is the major form of lung cancer in nonsmokers. Our goal in this paper was to determine if AC in smokers and nonsmokers represents the same genetic disease. We compared gene expression profiles in resected samples of nonmalignant lung tissue and tumor tissue in six never-smokers with AC and in six smokers with AC, who were matched for clinical staging and histologic criteria of cell differentiation. Results were analyzed using a variety of bioinformatic tools. Four times as many genes changed expression in the transition from noninvolved lung to tumor in nonsmokers as in smokers, suggesting that AC in nonsmokers evolves locally, whereas AC in smokers evolves in a field of genetically altered tissue. There were some similarities in gene expression in smokers and nonsmokers, but many differences, suggesting different pathways of cell transformation and tumor formation. Gene expression in the noninvolved lungs of smokers differed from that of nonsmokers, and multidimensional scaling showed that noninvolved lungs of smokers groups with tumors rather than noninvolved lungs of nonsmokers. In addition, expression of a number of genes correlated with smoking intensity. Our findings, although limited by small sample size, suggest that additional studies comparing noninvolved to tumor tissue may identify pathogenetic mechanisms and therapeutic targets that differ in AC of smokers and nonsmokers.

Effectiveness of home visits by mental health nurses for Japanese women with post-partum depression.

2008-12-01

Post-partum depression affects 10-13% of Japanese women, but many do not receive appropriate treatment or support. This intervention study evaluated the effectiveness of home visits by mental health nurses for Japanese women with post-partum depression. Eighteen post-partum women met the inclusion criteria and were randomly allocated into the intervention (n = 9) or control (n = 9) group at 1-2 months after giving birth. The intervention group received four weekly home visits by a mental health nurse. Control group participants received usual care. Two women in the intervention group did not complete the study. Depressive symptoms and quality of life were measured at 1 and 6 weeks' postintervention. In addition, participants completed an open-ended questionnaire on satisfaction and meaning derived from the home visits. Women in the intervention group had significant amelioration of depressive symptoms over time and reported positive benefits from the home visits, but there were no statistically significant differences between groups. Significant differences (P < 0.05) were observed at times 2 and 3 between groups in terms of increased median scores of physical, environmental, and global subscales, and the total average score of the World Health Organization/quality of life assessment instrument. On the psychological subscale, significant differences (P = 0.042) were observed between groups at time 2. The qualitative analysis of comments about home visitation revealed four categories related to 'setting their mind at ease', 'clarifying thoughts', 'improving coping abilities', and 'removing feelings of withdrawal from others'. These results suggest that home visits by mental health nurses can contribute to positive mental health and social changes for women with post-partum depression. A larger trial is warranted to test this approach to care.

Associations of gender role attitudes with fertility intentions: A Japanese population-based study on single men and women of reproductive ages.

Japan has been experiencing low fertility for many years. In this study, I investigated the relationship between gender role attitudes and fertility intentions among Japanese single men and women of reproductive ages. Utilizing the Longitudinal Survey of Adults in the 21st Century data, 8944 men and 7924 women aged 20-34 years with single, childless status were analyzed. Gender role attitudes were assessed by participants' preferences for the division of labor between a man and a woman: income earning, housework, and childcare. Those who preferred men to earn income and women to perform housework and childcare were considered to have traditional attitudes, whereas those who preferred women and men to share these responsibilities were considered to have egalitarian attitudes. Outcomes were fertility intentions measured by a desire to have children and ideal number of children. Logistic regression analyses were conducted. Egalitarian attitudes about income earning and housework were associated with low fertility intentions (a lesser desire for children) compared to traditional attitudes: adjusted odds ratios were 1.56 [1.36, 1.80] for men and 1.47 [1.26, 1.72] for women with income earning. Men's preference for sharing childcare responsibility was associated with high fertility intentions. Japanese society has not shifted away from the traditional division of labor despite the increase in female labor force participation. Low fertility intentions among Japanese men and women with egalitarian attitudes suggest that institutional support for balancing work and family may be necessary to improve the low fertility trend.

Adenosine upregulates the expression of vascular endothelial growth factor and fibroblast growth factor-7 in cultured dermal papilla cells. It has been shown that, in Japanese men, adenosine improves androgenetic alopecia due to the thickening of thin hair due to hair follicle miniaturization. To investigate the efficacy and safety of adenosine treatment to improve hair loss in women, 30 Japanese women with female pattern hair loss were recruited for this double-blind, randomized, placebo-controlled study. Volunteers used either 0.75% adenosine lotion or a placebo lotion topically twice daily for 12 months. Efficacy was evaluated by dermatologists and by investigators and in phototrichograms. As a result, adenosine was significantly superior to the placebo according to assessments by dermatologists and investigators and by self-assessments. Adenosine significantly increased the anagen hair growth rate and the thick hair rate. No side-effects were encountered during the trial. Adenosine improved hair loss in Japanese women by stimulating hair growth and by thickening hair shafts. Adenosine is useful for treating female pattern hair loss in women as well as androgenetic alopecia in men.

Although established adult smokers with long histories of nicotine dependence have lower neural tissue volume than non-smokers, it is not clear if lower regional brain volume is also observed in younger, less established smokers. The primary goal of this study was to investigate neural tissue volume in a large group of smokers and non-smokers, with a secondary goal of measuring the impact of age on these effects. We used voxel-based morphometry to compare regional gray matter volume in 118 individuals (59 smokers, 59 age- and gender-matched non-smokers). Younger smokers had significantly lower gray matter volume in the left thalamus and the left amygdala than their non-smoking peers (family-wise error-corrected clusters, P < 0.05). There was no correlation between smoking use variables and tissue volume among younger smokers. Established smokers had significantly lower gray matter volume than age-matched non-smokers in the insula, parahippocampal gyrus and pallidum. Medial prefrontal cortex gray matter volume was negatively correlated with pack-years of smoking among the established smokers, but not the younger smokers. These data reveal that regional tissue volume differences are not limited exclusively to established smokers. Deficits in young adults indicate that cigarette smoking may either be deleterious to the thalamus and amygdala at an earlier age than previously reported, or that pre-existing differences in these areas may predispose individuals to the development of nicotine dependence.

The prevalence of chronic obstructive pulmonary disease (COPD) in smokers enrolled as "healthy" controls in studies is 10-50%. The COPD status of ideal smoker populations for lung cancer case-control studies should be checked via spirometry; however, this is often not feasible, because no medical indications exist for asymptomatic smokers to undergo spirometry prior to study enrollment. Therefore, there is an unmet need for robust, cost effective assays for identifying undiagnosed lung disease among asymptomatic smokers. Such assays would help excluding unhealthy smokers from lung cancer case-control studies. We used the cytokinesis-blocked micronucleus (CBMN) assay (a measure of genetic instability) to identify undiagnosed lung disease among asymptomatic smokers. We used a convenience population from an on-going lung cancer case-control study including smokers with lung cancer (n = 454), smoker controls (n = 797), and a self-reported COPD (n = 200) contingent within the smoker controls. Significant differences for all CBMN endpoints were observed when comparing lung cancer to All controls (which included COPD) and Healthy controls (with no COPD). The risk ratio (RR) was increased in the COPD group vs. Healthy controls for nuclear buds (RR 1.28, 95% confidence interval 1.01-1.62), and marginally increased for micronuclei (RR 1.06, 0.98-1.89) and nucleoplasmic bridges (RR 1.07, 0.97-1.15). These findings highlight the importance of using truly healthy controls in studies geared toward assessment of lung cancer risk. Using genetic instability biomarkers would facilitate the identification of smokers susceptible to tobacco smoke carcinogens and therefore predisposed to either disease.

Rationale and Objectives There are limited data on, and controversies regarding gender differences in the airway dimensions of smokers. Multi-detector CT (MDCT) images were analyzed to examine whether gender could explain differences in airway dimensions of anatomically matched airways in smokers. Materials and Methods We used VIDA imaging software to analyze MDCT scans from 2047 smokers (M:F, 1021:1026) from the COPDGene® cohort. The airway dimensions were analyzed from segmental to subsubsegmental bronchi. We compared the differences of luminal area, inner diameter, wall thickness, wall area percentage (WA%) for each airway between men and women, and multiple linear regression including covariates (age, gender, body sizes, and other relevant confounding factors) was used to determine the predictors of each airway dimensions. Results Lumen area, internal diameter and wall thickness were smaller for women than men in all measured airway (18.4 vs 22.5 mm2 for segmental bronchial lumen area, 10.4 vs 12.5 mm2 for subsegmental bronchi, 6.5 vs 7.7 mm2 for subsubsegmental bronchi, respectively p < 0.001). However, women had greater WA% in subsegmental and subsubsegmental bronchi. In multivariate regression, gender remained one of the most significant predictors of WA%, lumen area, inner diameter and wall thickness. Conclusion Women smokers have higher WA%, but lower luminal area, internal diameter and airway thickness in anatomically matched airways as measured by CT scan than do male smokers. This difference may explain, in part, gender differences in the prevalence of COPD and airflow limitation. PMID:21756032

Longer lives and extended retirement have created a 'young old age' stage of life. How people spend their "young old age" has become increasingly important. This research aims to investigate the different ageing experiences of Japanese and Malaysian women and the activities they engaged in their "young old age". In-depth interviews were conducted to collect data and an adapted grounded theory approach was used for data analysis. Findings reveal many common characteristics for both groups of research participants. The emerging themes show that Japanese and Malaysian Chinese have different life missions evident in their daily activities, one passing on culture and the other passing on family values and life experience. They also differ in their choice of living arrangement (independent versus dependent/interdependent), attitudes to life (fighting versus accepting) and activities in which to engage (aesthetic pursuits versus family oriented activities).

To examine the associations between the pre-pregnancy body mass index (BMI) and gestational weight gain (GWG) with pregnancy outcomes in Japanese women. The medical records of 1883 Japanese women who delivered singleton infants from January 2010 to January 2013 at Osaka-Minami Medical Center were retrospectively reviewed. We use the BMI classification which the World Health Organization defined for Asian populations and the GWG classified based on the current 2009 Institute of Medicine (IOM) recommendations. The odds ratio (OR) of each of the groups for the different pregnancy outcomes were compared to the recommended group using a logistic regression analysis adjusted by age, gestational weeks, parity, weight gain, mode of delivery, pregnancy induced hypertension (PIH) and gestational diabetes mellitus. Women who were obese (BMI, ≥25 kg/m(2) ) and overweight (BMI, 23-24.9 kg/m(2) ) had a higher rate of developing PIH (adjusted OR, 6.68 and 3.21 [95% confidence interval [CI], 3.31-13.3 and 1.29-7.24]). In contrast, GWG exhibited a correlation with the weight of the infant. The inadequate GWG group had a higher rate of small-for-gestational age (SGA) infants (adjusted OR, 1.72 [95% CI, 1.22-2.46]). The rate of emergency cesarean section was not significantly different between the groups. A pre-pregnancy BMI less than 23 kg/m(2) is desirable to prevent Japanese women from developing PIH. GWG within the IOM recommendations also reduced the risk of PIH and SGA. © 2014 The Authors. Journal of Obstetrics and Gynaecology Research © 2014 Japan Society of Obstetrics and Gynecology.

The objectives of this clinical study were to demonstrate a reduction in exposure to selected harmful and potentially harmful constituents (HPHCs), and to assess product use behavior, in Japanese healthy adult smokers who switched to a novel tobacco vapor product (NTV). 60 smokers were randomly assigned for 5 days to either (a) a group who switched to an NTV (n = 20), (b) a group who continued to smoke their own brand of conventional cigarettes (CC, n = 20) or (c) a smoking abstinence group (SA, n = 20). Fifteen biomarkers of exposure (BoEs) to 14 HPHCs and pyrene were measured at baseline, day 3 and 5. Product use behavior was assessed by measuring product consumption, nicotine uptake and puffing topography. During investigations, increases were observed in product consumption and total puff volume in NTV group subjects as compared to baseline. Additionally, nicotine uptake in the NTV group was approximately half that observed in the CC group. BoE values were significantly reduced in the NTV group as compared to those in the CC group. Significantly, the magnitude of the reduction in exposure to HPHCs observed in the NTV group (49-94%) was close to that observed for the SA group (39-95%). Copyright © 2018 Elsevier Inc.

The image of a cigarette in a woman's hand symbolizes independence, non-conformity and personal power, despite widespread awareness that smoking has serious health risks. Through a content analysis of North American and British editions of Vogue, we trace the representation of women smokers from the 1920s-1960s. Vogue located the cigarette within the culture of the feminine elite. We explore the place of cigarette smoking within the constellation of behaviours and appearances presented as desirable characteristics of elitism, through the themes of lifestyle, "the look," and feminine confidence. We chart these themes' transformations over time and national contexts.

Objective Uterus transplantation (UTx) is a potential option for women with uterine factor infertility to have a child, but there has been no large-scale survey of the views on UTx in women of reproductive age in Japan. The present study was aimed to clarify the views of Japanese women of reproductive age on UTx for uterine factor infertility. Methods A questionnaire on UTx was conducted by an Internet research company in December 2014 as a cross-sectional study in 3,892 randomly chosen women aged 25 to 39 years old. Responses were analyzed from 3,098 subjects (mean age 32.1±4.2 years old), after exclusion of inappropriate respondents in screening. Results Of the respondents, 62.1%, 34.7% and 18.1% favored adoption, UTx and gestational surrogacy, respectively. In contrast, 7.0%, 21.9% and 63.3% opposed adoption, UTx and gestational surrogacy, respectively. In choices of candidates for UTx based on highest priority, deceased persons (33.8%) and mothers (19.0%) were favored as donors, and women with congenital absence of the uterus (54.4%) and hysterectomy due to a malignant uterine tumor (20.0%) as recipients. Regarding societal acceptance of UTx, the answer rates were 15.7% for "UTx should be permitted", 77.6% for "UTx should be permitted with discussion", and 6.7% for "UTx should not be permitted, even with discussion". Regarding personal opinions on UTx, 44.2% were in favor, 47.5% had no opinion, and 8.3% were against. Conclusion Our results suggest that many Japanese women of reproductive age feel that UTx is socially and individually acceptable, but that concerns requiring further discussion remain among these women. There was also a tendency for UTx to be viewed more favorably than gestational surrogacy. PMID:27203855

Some women with depressive disorders experience severe premenstrual symptoms. However, there have been few studies in which premenstrual symptoms in women suffering from depressive disorders were assessed. In this study, we aimed to investigate premenstrual symptoms in women with depressive disorders using the premenstrual dysphoric disorder (PMDD) scale. We administered questionnaires to 65 Japanese female outpatients who had been diagnosed with a major depressive disorder or dysthymic disorder and to 303 healthy women as control subjects. The questionnaire consisted of items on demographics and the PMDD scale, which was modified from the premenstrual symptoms screening tool (PSST) developed by Steiner et al. (Arch Womens Ment Health 2003, 6:203-209). Twenty-eight women (43.1%) with depressive disorder fulfilled certain items of the PMDD scale. These women are considered to have coexisting PMDD and a depressive disorder, or to have premenstrual exacerbation (PME) of a depressive disorder. On the other hand, 18 women (5.9%) in the control group were diagnosed as having PMDD. The depressive disorder group who fulfilled the PMDD criteria had more knowledge of the term premenstrual syndrome (PMS) and took more actions to attenuate premenstrual symptoms than the control group with PMDD. Our findings demonstrated that the occurrence of severe premenstrual symptoms is much higher in women with depressive disorders than in healthy subjects. This is partially due to this group containing women with PME, but mainly due to it containing women with PMDD. The higher percentage of PMDD suggests similarity between PMDD and other depressive disorders. Furthermore, educating healthy Japanese women and women with depressive disorders about premenstrual symptoms and evidence-based treatment for them is necessary.

Background Some women with depressive disorders experience severe premenstrual symptoms. However, there have been few studies in which premenstrual symptoms in women suffering from depressive disorders were assessed. In this study, we aimed to investigate premenstrual symptoms in women with depressive disorders using the premenstrual dysphoric disorder (PMDD) scale. Methods We administered questionnaires to 65 Japanese female outpatients who had been diagnosed with a major depressive disorder or dysthymic disorder and to 303 healthy women as control subjects. The questionnaire consisted of items on demographics and the PMDD scale, which was modified from the premenstrual symptoms screening tool (PSST) developed by Steiner et al. (Arch Womens Ment Health 2003, 6:203-209). Results Twenty-eight women (43.1%) with depressive disorder fulfilled certain items of the PMDD scale. These women are considered to have coexisting PMDD and a depressive disorder, or to have premenstrual exacerbation (PME) of a depressive disorder. On the other hand, 18 women (5.9%) in the control group were diagnosed as having PMDD. The depressive disorder group who fulfilled the PMDD criteria had more knowledge of the term premenstrual syndrome (PMS) and took more actions to attenuate premenstrual symptoms than the control group with PMDD. Conclusions Our findings demonstrated that the occurrence of severe premenstrual symptoms is much higher in women with depressive disorders than in healthy subjects. This is partially due to this group containing women with PME, but mainly due to it containing women with PMDD. The higher percentage of PMDD suggests similarity between PMDD and other depressive disorders. Furthermore, educating healthy Japanese women and women with depressive disorders about premenstrual symptoms and evidence-based treatment for them is necessary. PMID:21535889

In this study, we conducted an empirical survey of the avoidance behaviors and risk perceptions of active and passive smoking pregnant smokers and recent quitters. We employed an online questionnaire survey by recruiting 166 voluntary participants from an online parenting community in Taiwan. The results of the empirical survey revealed that three-fourths of smokers quit smoking during pregnancy and one-fourth continued smoking. All pregnant women who continued smoking had partners or lived with relatives who smoked. Current smokers and quitters differed significantly in their risk perceptions and attitudes toward smoking during pregnancy. Most pregnant smokers and quitters adopted passive smoking avoidance behaviors at home and in public. Nevertheless, one-fifth of pregnant women chose not to avoid passive smoking. We concluded that most women stop smoking during pregnancy; however, most women continue to be exposed to passive-smoking environments. Perceived fetal health risks and attitudes toward smoking during pregnancy are critical predictors of the anti-smoking behaviors of pregnant women. PMID:24005830

Little is known about the relation of modifiable dietary factors to circulating adiponectin concentrations, particularly in young adults and non-Western populations. The aim of this study was to determine the association between macronutrient and food intake and serum adiponectin concentration in a group of young Japanese women. This cross-sectional study included 1047 female Japanese dietetic students aged 18 to 22 y. Using a validated, self-administered, comprehensive diet history questionnaire, we assessed intake of nutrients (protein, total fat, saturated fatty acids, monounsaturated fatty acids, and polyunsaturated fatty acids, carbohydrates, and dietary fiber) and foods (rice, bread, noodles, potatoes, confectioneries, fats and oils, pulses, fish and shellfish, meats, eggs, dairy products, vegetables, fruits, coffee, green and oolong tea, black tea, and soft drinks) and glycemic index and load. Fasting blood samples were collected and serum adiponectin concentrations were measured. Adjustment was made for survey year, region, municipality level, current smoking, current alcohol drinking, physical activity, body mass index, energy intake, and intakes of other nutrients or foods. After adjustment for potential confounding factors, none of the nutrients examined was a significant determinant of serum adiponectin concentration. There was no association for glycemic index or load. Coffee was the only food significantly and independently associated with serum adiponectin concentration. Mean (SE) values of serum adiponectin concentration for each quartile of coffee intake were 12.4 (0.2), 12.4 (0.5), 12.5 (0.3), and 13.2 (0.3) μg/mL, respectively (P for trend = 0.04). In a group of young Japanese women, higher coffee intake was independently associated with higher serum adiponectin concentration. Copyright © 2013 Elsevier Inc. All rights reserved.

Supplementation studies have suggested a role of n-3 polyunsaturated fatty acids (PUFAs) in homocysteine metabolism, but the evidence is limited and inconsistent among studies that measured blood levels of n-3 and n-6 PUFAs. We examined the association between blood levels of PUFAs and homocysteine in Japanese men and women. The subjects were 496 employees (290 men and 206 women) of 2 municipal offices in Japan. Fatty acid composition in serum phospholipids and cholesterol ester (CE) was measured using gas-liquid chromatography. Multiple regression was used to calculate means of homocysteine concentrations according to PUFA tertile with adjustment for potential confounders. Serum homocysteine concentration decreased with increasing levels of total n-3 PUFA, eicosapentaenoic acid and docosahexaenoic acid (DHA) in serum phospholipids and CE with adjustment for age, sex and workplace. However, only DHA in serum phospholipids remained statistically significant after additional adjustment for other potential confounders including serum folate (P-trend = 0.04). N-6 PUFAs were not significantly associated with homocysteine concentrations. Higher proportion of DHA in serum phospholipids may be associated with lower homocysteine concentrations in Japanese men and women.

Classifying a Smoker Scale in Adult Daily and Nondaily Smokers

PubMed Central

2014-01-01

Introduction: Smoker identity, or the strength of beliefs about oneself as a smoker, is a robust marker of smoking behavior. However, many nondaily smokers do not identify as smokers, underestimating their risk for tobacco-related disease and resulting in missed intervention opportunities. Assessing underlying beliefs about characteristics used to classify smokers may help explain the discrepancy between smoking behavior and smoker identity. This study examines the factor structure, reliability, and validity of the Classifying a Smoker scale among a racially diverse sample of adult smokers. Methods: A cross-sectional survey was administered through an online panel survey service to 2,376 current smokers who were at least 25 years of age. The sample was stratified to obtain equal numbers of 3 racial/ethnic groups (African American, Latino, and White) across smoking level (nondaily and daily smoking). Results: The Classifying a Smoker scale displayed a single factor structure and excellent internal consistency (α = .91). Classifying a Smoker scores significantly increased at each level of smoking, F(3,2375) = 23.68, p < .0001. Those with higher scores had a stronger smoker identity, stronger dependence on cigarettes, greater health risk perceptions, more smoking friends, and were more likely to carry cigarettes. Classifying a Smoker scores explained unique variance in smoking variables above and beyond that explained by smoker identity. Conclusions: The present study supports the use of the Classifying a Smoker scale among diverse, experienced smokers. Stronger endorsement of characteristics used to classify a smoker (i.e., stricter criteria) was positively associated with heavier smoking and related characteristics. Prospective studies are needed to inform prevention and treatment efforts. PMID:24297807

Measuring urinary cotinine is a popular and established method of biologically monitoring exposure to tobacco smoke. However, the lower detection limit of cotinine often impedes the evaluation of passive (second-hand) smoking and this, together with unconverted nicotine, does not reflect actual levels of exposure. Furthermore, a portion of the Japanese population might have decreased ability to metabolize nicotine. The present study was therefore carried out to validate the simultaneous analysis of total concentrations of free nicotine and cotinine and their glucuronides to determine actual levels of voluntary and involuntary exposure to cigarette smoke. Urine samples from 118 Japanese smokers and 117 non-smokers were analyzed using gas chromatography-mass spectrometry. Voluntary and involuntary smoking status was self-reported and workplace smoking restrictions were objectively evaluated. The integrated sum of all concentrations showed 2.2- and 2.4-fold higher total levels (free and glucuronide) of nicotine and cotinine relative to the free levels. Median (quartiles) of total nicotine and cotinine were 1635 (2222) and 3948 (3512) ng/mL in smokers, and 3.5 (5.3) and 2.8 (4.2) ng/mL in non-smokers. Concentrations of urinary nicotine were higher than those of cotinine in 21 % of smokers and in 54 % of non-smokers. Nicotine and cotinine levels were significantly associated with a smoking habit, as well as being significantly associated with the workplace and home environments of non-smokers. The present method can monitor voluntary and involuntary exposure to tobacco smoke. Measuring total urinary nicotine levels might be useful for analyzing exposure to cigarette smoke among non-smokers.

 Although previous randomized and non-randomized studies have demonstrated the safety and efficacy of paclitaxel-eluting stents (PES), a higher revascularization rate has been reported in women than in men. A sub-analysis of the TAXUS Japan Post-market Surveillance Study (TAXUS-PMS) was done to assess the influence of gender on clinical outcome.  A total of 2,132 PES-treated Japanese patients (women, n=551) from this registry were analyzed. Subjects were stratified by gender to compare 1-year clinical outcome. PES-treated women were older and more likely to have insulin-treated diabetes and hypertension. In contrast, PES-treated men were more likely to be smokers, have a previous history of myocardial infarction, and lower ejection fraction. While cardiac death, myocardial infarction and stent thrombosis were similar between men and women, major cardiac events tended to be lower in women than in men (6.4% vs. 8.8%, P=0.08). Although women had significantly smaller reference vessel size (2.46±0.53 mm vs. 2.59±0.60 mm, P<0.0001), the restenosis rate tended to be lower in women than in men (11.5% vs. 14.8%, P=0.11). Subsequently, the target lesion revascularization rate was significantly lower in women than in men (4.2% vs. 6.5%, P<0.05).  Despite a higher risk profile, Japanese women treated with PES did not have a higher rate of repeat revascularization or major adverse clinical outcome than PES-treated men at 1 year.

Protective antioxidative effects of melatonin have been repeatedly documented in experimental and clinical studies. One of the most spectacular exogenous prooxidative agents is cigarette smoking. The aim of the study was to evaluate the level of oxidative damage to membrane lipids (lipid peroxidation; LPO) in blood serum, and in epidermis exfoliated during microdermabrasion collected from former-smokers who were treated with melatonin. The study was performed in postmenopausal women. Ninety (90) female volunteers, aged 46-67 years, were enrolled. Two major groups, i.e. never-smokers (n=44) and former-smokers (n=46), were divided into: Control, melatonin topical skin application, Restructurer (containing antioxidants) topical skin application, and melatonin oral treatment. Microdermabrasion was performed at point '0', after 2 weeks, and after 4 weeks of treatment. The following parameters were measured: LPO in blood serum, LPO in epidermis exfoliated during microdermabrasion, and skin biophysical characteristics, such as sebum, moisture, elasticity, and pigmentation. Malondialdehyde+4-hydroxyalkenals level (LPO index) was measured spectrophotometrically. Melatonin oral treatment significantly reversed the increased serum LPO level in former-smokers already after 2 weeks of treatment. In a univariate regression model, LPO blood level constituted the only independent factor negatively associated with melatonin oral treatment. After 4 weeks of treatment, melatonin given orally increased skin sebum, moisture and elasticity levels, and melatonin applied topically increased sebum level. Exogenous melatonin reverses the enhanced oxidative damage to membrane lipids and improves skin biophysical characteristics in former-smokers.

Genetic polymorphisms and sex differences are suggested to affect muscle fiber composition; however, no study has investigated the effects of genetic polymorphisms on muscle fiber composition with respect to sex differences. Therefore, the present study examined the effects of genetic polymorphisms on muscle fiber composition with respect to sex differences in the Japanese population. The present study included 211 healthy Japanese individuals (102 men and 109 women). Muscle biopsies were obtained from the vastus lateralis to determine the proportion of myosin heavy chain (MHC) isoforms (MHC-I, MHC-IIa, and MHC-IIx). Moreover, we analyzed polymorphisms in α-actinin-3 gene ( ACTN3; rs1815739 ), angiotensin-converting enzyme gene ( ACE; rs4341 ), hypoxia-inducible factor 1 α gene ( rs11549465 ), vascular endothelial growth factor receptor 2 gene ( rs1870377 ), and angiotensin II receptor, type 2 gene ( rs11091046 ), by TaqMan single-nucleotide polymorphism genotyping assays. The proportion of MHC-I was 9.8% lower in men than in women, whereas the proportion of MHC-IIa and MHC-IIx was higher in men than in women (5.0 and 4.6%, respectively). Men with the ACTN3 RR + RX genotype had a 4.8% higher proportion of MHC-IIx than those with the ACTN3 XX genotype. Moreover, men with the ACE ID + DD genotype had a 4.7% higher proportion of MHC-I than those with the ACE II genotype. Furthermore, a combined genotype of ACTN3 R577X and ACE insertion/deletion (I/D) was significantly correlated with the proportion of MHC-I ( r = -0.23) and MHC-IIx ( r = 0.27) in men. In contrast, no significant correlation was observed between the examined polymorphisms and muscle fiber composition in women. These results suggest that the ACTN3 R577X and ACE I/D polymorphisms independently affect the proportion of human skeletal muscle fibers MHC-I and MHC-IIx in men but not in women. NEW & NOTEWORTHY In men, the RR + RX genotype of the α-actinin-3 gene ( ACTN3) R577X polymorphism was

Smokers in Brazil: who are they?

Brazil has experienced a large decline in smoking prevalence due to several tobacco control policies that were implemented in the past 25 years. Previous population-wide studies found a consistent reduction over time in daily cigarette consumption among all socioeconomic groups. To examine changes between 2008 and 2013 in tobacco behaviours and health-related conditions of smokers. We used data obtained from two nationally-representative surveys conducted in 2008 and 2013 to estimate the prevalence of self-reported psychological and physical morbidity, and nicotine dependence markers, stratified by gender and sociodemographic groups. Generalised linear models were used to understand whether absolute differences in prevalence rates over time differed by categories of selected variables. For both genders, as smoking prevalence declined in Brazil, there has been an increase in the proportion of ever smokers who have quit. In addition, remaining smokers seem to be making more quitting attempts. Among men with low educational level or younger than 25 years-old, as compared to their counterparts, cessation rate showed an even greater increase over time. Moreover, the proportion of light smokers, which represent the vast majority of smokers, did not decrease. The percentage of poor health-conditions among remaining smokers nevertheless increased, particularly among women, which can make future cessation more challenging. In Brazil, quitting rate is increasing, thus suggesting that tobacco control interventions implemented in Brazil in the past years seem to be effectively reaching the smoking population. This is strong evidence against the 'hardening hypothesis', which posits that remaining smokers decrease their willingness and ability to quit. Published by the BMJ Publishing Group Limited.

The purpose of this research is to analyze cessation text-messages written by pregnant smokers to elucidate the target population's preferred content and message attributes. To achieve this goal, the objectives of this study are three-fold; to qualitatively code messages written by pregnant smokers for frame, type of appeal, and intended target. Study participants were recruited as part of a larger trial of pregnant smokers who were enrolled in a text-messaging program or control group and surveyed 1 month post-enrollment. Each participant was asked to write a brief message to another pregnant smoker and two independent coders qualitatively analyzed responses. User generated messages (N = 51) were equally loss and gain framed, and the most common appeals were: fear, guilt, cognitive, hope and empathy, in order of most to least frequent. The target of the majority of the messages was the baby. Allowing pregnant smokers to write cessation text-messages for other pregnant women can provide relevant insight into intervention content. Specifically, pregnant smokers appear to equally promote gain and loss frames, but may prefer messages that include components of fear and guilt related to the impact of smoking on their baby. Additional research is needed to systematically uncover perspectives of pregnant smokers to ensure interventions are optimally effective.

Aims/Introduction To determine the diagnostic potential of plasma lipids and apolipoproteins in gestational diabetes mellitus (GDM), we carried out a retrospective cohort study of 1,161 Japanese women at 20–28 weeks of gestation who underwent a glucose challenge test (GCT). Materials and Methods A total of 1,161 Japanese women at 20–28 weeks of gestation underwent a GCT. Participants with a positive test (GCT[+]) underwent a subsequent oral glucose tolerance test. Clinical and biochemical parameters were determined and quantification of apolipoproteins (Apo), including ApoB, ApoB48, ApoA-I and ApoC-III, was carried out. Results The prevalence of GCT(+; with a 130 mg/dL glucose cut-off) and GDM was 20% and 4%, respectively. There was a trend for increased triglycerides and ApoC-III in GDM(+) participants. However, the difference in plasma triglycerides, ApoC-III or ApoB48 did not reach statistical significance between GDM(+) and GDM(−) women. Values of 1-h glucose (P < 0.001) and fasting glucose (P = 0.002) were significant risk factors for GDM. Conclusions Prediction of GDM using only the ApoC-III value is not easy, although triglycerides and ApoC-III were higher in the GDM(+) group. The present findings show no significant difference in plasma lipid levels between women diagnosed with GDM and those with normal glucose tolerance. PMID:26543537

The Japanese Orthopaedic Association has proposed the term locomotive syndrome (LS) to designate a condition of individuals in high-risk groups with musculoskeletal disease who are highly likely to require nursing care. This study investigates the influence of spinal factors on LS in Japanese females. A total of 187 women > or =50 years old were enrolled in the study. Those answering yes to least one of the 7 categories in the self-assessment checklist for LS were defined as having LS. We evaluated lateral lumbar radiographs, sagittal parameters, sagittal balance using the spinal inclination angle (SIA) as an index, spinal range of motion (ROM) as determined with SpinalMouse, back muscle strength (BMS), and body mass index (BMI). Age, BMI, BMS, SIA, sacral slope angle (SSA), and lumbar spinal ROM showed significant correlations with LS. Multiple logistic regression analysis indicated that an increase in age (OR 1.054, p<0.05) and a decrease in BMS (OR 0.968, p<0.01) were significantly associated with LS. Age had significant negative correlations with BMS, SSA, thoracic and lumbar spinal ROM, and it had positive correlations with BMI, SIA, and lumbar kyphosis. BMS had significant negative correlations with age, SIA, thoracic and lumbar kyphosis, and it had positive correlations with SSA, lumbar and total spinal ROM. An increase in age and a decrease in BMS may be the most important risk factors for LS in Japanese women. Back muscle strengthening and spinal ROM exercises could be useful for improving the status of an individual suffering from LS.

Recent neuroimaging research suggests sex-related brain differences in smoking addiction. In the present pilot study, we assessed gender-related differences in brain activation in response to cigarette-related video cues, investigating non-smokers, smokers, and ex-smokers. First, we compared 29 females (28.6 ± 5.3) vs. 23 males (31.5 ± 6.4), regardless of current smoking status to assess global gender-related effects. Second, we performed a post hoc analysis of non-smokers (9 females and 8 males), smokers (10 females and 8 males), and ex-smokers (10 females and 7 males). Participants performed a block-design functional magnetic resonance imaging paradigm contrasting smoking with control cue video exposures. Data analyses included task-related general linear model, voxel-based morphometry of gray matter (GM), and tract-based spatial statistics of white matter (WM). First, the global effect regardless of current smoking status revealed higher activation in the bilateral superior frontal gyrus and anterior cingulate cortex (ACC) for females compared to males. Second, the analysis according to current smoking status demonstrated higher activation in female vs. male smokers vs. non-smokers in the superior frontal gyrus, anterior and posterior cingulate cortex, and precuneus, and higher activation in female vs. male ex-smokers vs. non-smokers in the right precentral gyrus, in the right insula and ACC. No structural differences were found in GM or WM. The current study identifies gender-related brain functional differences in smokers and ex-smokers compared to non-smokers. The current work can be considered as a starting point for future investigations into gender differences in brain responses to cigarette-related cues.

To investigate the association between smoking and health-related quality of life (HRQOL) in a rural Japanese population. A cross-sectional study of data from 823 subjects in Iwaki area of Hirosaki City, Japan. SF-36 scores between non-smokers and smokers were compared. To test the sensitivity of SF-36 scores in detecting health deterioration, effects of having diseases and having deviations from normal thresholds in health check-up were analyzed by adding them into covariates in ANCOVA. There was no significant difference in SF-36 scores between non-smokers and smokers. Presence of diseases significantly decreased the physical components of SF-36 scores while the results of health check-up had no significant influence on SF-36 scores. The results suggested the possibility that in Japan, where smoking prevalence is still relatively high, smokers may be less sensitive to sub-clinical deterioration in their own health status than smokers in Western countries that already have experienced the major decline in their smoking rate. The importance of having the smoker become more sensitive to the sub-clinical adverse effects of cigarette smoking should be stressed for the success of smoking control programs.

Few studies have examined the health effects of employment situation among women, taking social and economic conditions into consideration. The objective of this research was to investigate the association of employment situation (full-time or part-time employee and self-employed) with mortality risk in women over a 20-year follow-up period. Additionally, we examined whether the association between employment situation and mortality in women differed by education level and marital status. We investigated the association of employment situation with mortality among 16,692 women aged 40-59 years enrolled in the Japan Collaborative Cohort Study. Multivariate HRs and 95% CIs for total deaths by employment situation were calculated after adjustment for age, disease history, residential area, education level, marital status and number of children. We also conducted subgroup analysis by education level and marital status. Multivariate HRs for mortality of part-time employees and self-employed workers were 1.48 (95% CI, 1.25 to 1.75) and 1.44 (95% CI, 1.21 to 1.72), respectively, with reference to women working full-time. Subgroup analysis by education level indicated that health effects in women according to employment situation were likely to be more evident in the low education-level group. Subgroup analysis by marital status indicated that this factor also affected the association between employment situation and risk of death. Among middle-aged Japanese women, employment situation was associated with mortality risk. Health effects were likely to differ by household structure and socioeconomic conditions.

To determine the relationship between the working situation (full-time housewife, stopped working during pregnancy, or currently employed) and the lifestyle factors, reasons for stopping work during pregnancy, and effects of working conditions in order to identify the factors that are related to the continuation of employment among pregnant Japanese women. In a cross-sectional study, a questionnaire was administered to pregnant women who visited an obstetrics clinic in a Tokyo suburb for an outpatient medical check-up during July and August 2004. The data of 530 healthy pregnant women were analyzed. The pregnant women who stopped working during their pregnancy had lower mental health scores than the full-time housewives and employed pregnant women. In each trimester, the employed pregnant women reported a shorter daytime sleep duration than the pregnant women who stopped working during their pregnancy and the full-time housewives. The reasons for stopping work during pregnancy were categorized as somatic symptoms due to pregnancy, working conditions, and a sense of values or social reasons. The employed women in the third trimester more often reported the availability of, and access to, a rest area in their company, compared to those in the first and second trimesters. The lifestyle factors of the pregnant women were different, based on their work situation. In particular, the employed pregnant women had a shorter daytime sleep duration. The pregnant women who stopped working during their pregnancy could have benefited from mental health support. In addition, the reasons for stopping work during pregnancy were different in the three trimesters. A flexible system is needed for working women that adapts to the physical changes that occur during pregnancy. © 2011 The Authors.

Intake of green tea may reduce the risk of breast cancer; polyphenols in this drink can influence enzymes that metabolize estrogens, known causal factors in breast cancer etiology. We examined the associations of green tea intake (<1 time/week, 1-6 times weekly, or 7+ times weekly) with urinary estrogens and estrogen metabolites (jointly EM) in a cross-sectional sample of healthy Japanese American women, including 119 premenopausal women in luteal phase and 72 postmenopausal women. We fit robust regression models to each log-transformed EM concentration (picomoles per mg creatinine), adjusting for age and study center. In premenopausal women, intake of green tea was associated with lower luteal total EM (P trend=0.01) and lower urinary 16-pathway EM (P trend=0.01). In postmenopausal women, urinary estrone and estradiol were approximately 20% and 40% lower (P trend=0.01 and 0.05, respectively) in women drinking green tea daily compared to those drinking<1 time/week. Adjustment for potential confounders (age at menarche, parity/age at first birth, body mass index, Asian birthplace, soy) did not change these associations. Findings suggest that intake of green tea may modify estrogen metabolism or conjugation and in this way may influence breast cancer risk.

Objective: This study investigated the correlation between participation in the treatment decision-making process and satisfaction with the process among Japanese women with breast cancer. The influence of sociodemographic and clinical characteristics on satisfaction with the treatment decision-making process was also examined. Methods: We conducted a cross-sectional, self-administered internet survey of 650 Japanese women with breast cancer in March 2016. Decisional role (active, collaborative, passive) in the treatment decision-making was elicited using the Japanese version of the Control Preference Scale. Satisfaction with the decision-making process was assessed. Result: About half of the participants preferred to play a collaborative role, while half of the participants perceived that they played an active role. Satisfaction among the participants who made their treatment choice collaboratively with their physicians was significantly higher than that of participants who made the choice by themselves or entrusted their physicians to make the decision. However, two-way ANOVA demonstrated that satisfaction level was associated with the congruence between the participants’ preferred and actual decisional roles, but not with the actual decisional roles that they played. This association had no interaction with sociodemographic and clinical status, except for education level. A majority of the participants who participated in the roles they preferred in choosing their treatment option indicated that they would participate in the same role if they were to face a similar decision-making situation in the future. Conclusion: Regardless of their role played in the cancer treatment decision-making process, and irrespective of their sociodemographic and clinical status, Japanese women with breast cancer are more satisfied with the treatment decision-making process when their participation in the process matches their preferred role in the process.

A group of thirty-eight women under age 70 who sustained vertebral compression fractures during minor trauma included more postmenopausal smokers than a group of 34 similar women with fractures resulting from major trauma and more than a group of 572 other women. Advanced idiopathic osteoporosis occurring before age 65 was found rarely among nonsmokers. The percent cortical area at the second metacarpal midpoint was measured in 103 white women aged 40 to 49 years, and 208 white women aged 60 to 69 years. In the younger group, no quantitative differences were demonstrated between bones of the obese and the nonobese or between smokers and nonsmokers. In contrast, among the older group, postmenopausal smokers exhibited much more bone loss than did nonsmokers (P less than .001), and nonobese women demonstrated much more bone loss than did obese women, this difference being most striking among smokers.

Given that tobacco smoking habit is a risk factor for periodontal diseases, the aim of this study was to compare clinical periodontal aspects between smokers and non-smokers. The clinical status were assessed in 55 patients, 29 smokers and 26 non-smokers, aged 30 to 50 years, with mean age of 40. The clinical parameters used were: probing depth (PD), plaque index (PI), gingival index (GI), clinical attachment level (CAL), gingival recession (GR) and gingival bleeding index (GBI) for arches (upper and lower) and teeth (anterior and posterior). Tooth loss was also evaluated in both groups. Multiple regression analysis showed: tendency of greater probing depth and clinical attachment level means for smokers; greater amount of plaque in smokers in all regions; greater gingival index means for non-smokers with clinical significance (p<0.05) in all regions. Although, without statistical significance, the analysis showed greater gingival bleeding index means almost always for non-smokers; similar gingival recession means in both groups and tendency of upper tooth loss in smokers and lower tooth loss in non-smokers. The findings of this study showed that clinical periodontal parameters may be different in smokers when compared to non-smokers and that masking of some periodontal signs can be a result of nicotine's vasoconstrictor effect.

Cervical cancer incidence and mortality is increasing in Japanese women under age 50. Screening uptake is low and proactive recommendations for human papillomavirus vaccination have been suspended. Other cervical cancer prevention initiatives are urgently needed. We assessed whether human papillomavirus self-sampling might be an acceptable alternative to physician-led screening, particularly in women with limited experience of tampon use. We also sought to identify any practical, logistical, or safety issues in women already attending for screening, before carrying out further large-scale studies in non-responders. In total, 203 women aged 20-49 attending their annual workplace healthcheck in Sapporo, northern Japan, performed unsupervised human papillomavirus self-sampling before undergoing a physician-led cervical smear and human papillomavirus test, and completing a measure of acceptability for both tests. Ninety per cent of participants stated they would use self-sampling again. They found instructions easy to follow and reported no issues with the usability of the self-sampling device. Compared with physician-led testing, women found self-sampling significantly less painful, less embarrassing and could relax more (p < 0.001), regardless of history of tampon use, which was associated with negative experiences in physician sampling (p = 0.034). Women lacked confidence the test had been performed correctly, despite no unsatisfactory samples. No safety issues were reported. Self-sampling was highly acceptable in this population of women. They could perform the test safely unsupervised, but lacked confidence the test has been carried out correctly. Japanese women need to be educated about the accuracy of human papillomavirus self-sampling and further large-scale studies are necessary in non-responders. © The Author(s) 2016.

To explore the predictive value of subjective social status (SSS-US and SSS-Community) on readiness to quit among 245 homeless smokers. Hierarchical multiple regression analyses were conducted (stratified by sex). Higher SSS-US (p = .02) and SSS-Community (p < .001) predicted greater readiness to quit in the total sample. These relationships upheld for men (p's <. 01), but only SSS-Community predicted readiness to quit for women (p = .02). Higher SSS is associated with greater readiness to quit among homeless smokers. SSS-Community may be a more relevant index of SSS for women relative to SSS-US. Results suggest SSS may be a factor that contributes to smoking, disease, and health disparities.

Prenatal smoking is a preventable risk factor for poor perinatal outcomes and is more prevalent in pregnant smokers of low socioeconomic status (SES). We describe the intervention model and factors associated with quitting from the Pittsburgh STOP Program, an evidence-informed dissemination intervention for low-SES pregnant smokers. STOP is delivered in community health care clinics serving economically disadvantaged women. Participants were 856 pregnant women who were current smokers (93%) and recent quitters (7%). Most were white (59%) or black (35%), single (74%), young (mean age = 25), and experiencing an unplanned pregnancy (84%); 90% were insured by Medicaid/uninsured. An evidence-informed intervention for community pregnant women was delivered individually in a single-group pre-post evaluation design. Measures were demographics, participation and retention, smoking status, satisfaction, and cost. Analyses included descriptive statistics and logistic regression. Participants attended an average of 4.7 sessions. Dropout rate after the first session was 5%. Over 11% of smokers quit; 48% of preenrollment spontaneous quitters remained abstinent. Factors significantly associated with quitting included race, mother's age, nicotine dependence, and number of sessions attended. STOP is a community program with self-selected participants and no control group. Low-income pregnant smokers will engage in an evidence-informed cessation program tailored for this group, with quit rates that compare to controlled research results.

The purpose of this study was to assess whether pregnant smokers have the same nicotine intake from cigarettes as a general population of smokers and whether the known lower daily cigarette consumption among pregnant smokers is associated with higher nicotine intake among pregnant smokers. The study was a cross-sectional comparison of pregnant smokers and a general population of smokers in smoking cessation clinics. Participants were treatment-seeking pregnant (n = 476), nonpregnant female (n = 116), and male (n = 195) smokers who participated in two independent smoking cessation trials. Nicotine intake was measured as saliva cotinine/ cigarette/kg body weight ratio. The mean saliva cotinine (μg/L)/ cigarette/kg body weight (0.21, SD = 0.15) of pregnant smokers was similar to that of nonpregnant female smokers (0.24, SD = 0.14) and higher than that of male smokers (0.18, SD = 0.12, p = .002) despite a substantially lower number of cigarettes per day (pregnant smokers: 12, SD = 6; nonpregnant female smokers: 26.6, SD = 11.7; male smokers: 23.5, SD = 9.5, p < .001). Among pregnant smokers, saliva cotinine, as expected, increased in parallel with the number of cigarettes per day, but nicotine intake (cotinine/cigarette/kg body weight) was inversely associated with daily cigarette consumption (p < .001). No association between cigarettes per day and nicotine intake was observed in male and nonpregnant female smokers (p = .43). This secondary analysis showed that pregnant smokers' nicotine intake was similar to that of a general population of smokers despite a lower cigarette consumption rate. Among pregnant smokers, lower daily cigarette consumption was associated with higher nicotine intake from cigarettes, suggesting compensatory smoking.

To determine associations of maternal pre-pregnancy underweight with poor outcomes and evaluate how gestational weight gain affects risks for such outcomes in pre-pregnancy underweight Japanese women. By analyzing the January 2001-December 2012 hospital database, we retrospectively identified 6954 women with pre-pregnancy normal weights (body mass index, 18.5-24.9 kg/m²) and 1057 pre-pregnancy underweight women (body mass index, <18.5 kg/m²) who delivered at the Perinatal Maternity and Neonatal Center of Yokohama City University. These women were stratified by weekly weight gain during the second/third trimesters to investigate associations of gestational weight gain with spontaneous preterm birth and small for gestational age (SGA). Spontaneous preterm birth and SGA incidences were compared with those of women meeting Institute of Medicine (IO M) guidelines to determine optimal weight gain in Japanese women. Preterm birth and SGA incidences were significantly higher in pre-pregnancy underweight than in pre-pregnancy normal weight women (4.6% vs 2.4% [P=0.005] and 13.9% vs 9.7% [P = 0.003], respectively). For pre-pregnancy normal weight women, preterm birth incidence was significantly higher in those with weight gain of less than 0.2 kg/week than in those IOM guidelines. For pre-pregnancy underweight women, preterm birth and SGA incidences were significantly higher in those with weight gain of less than 0.3 kg/week than in those meeting IOM guidelines. Preterm birth and SGA incidences did not differ significantly between pre-pregnancy normal weight women with weight gain of 0.2 kg/week or more and pre-pregnancy underweight women with weight gain of 0.3 kg/week or more, as compared to women meeting IOM guidelines. These results suggest that IOM guidelines for gestational weight gain may lack external validity in Japanese women. © 2014 The Authors.

Women face particular challenges when quitting smoking, especially those with weight concerns. A multi-behavioral smoking cessation intervention addressing these concerns and incorporating guided imagery may assist women to engage in healthy lifestyle behaviors. An mHealth app can easily disseminate such an intervention. The goals of this pilot study were to develop and test the feasibility and potential of the See Me Smoke-Free ™ mHealth app to address smoking, diet, and physical activity among women smokers. We used pragmatic, direct-to-consumer methods to develop and test program content, functionality, and the user interface and conduct a pre-/post-test, 90-day pilot study. We enrolled 151 participants. Attrition was 52%, leaving 73 participants. At 90 days, 47% of participants reported 7-day abstinence and significant increases in physical activity and fruit consumption. Recruitment methods worked well, but similar to other mHealth studies, we experienced high attrition. This study suggests that a guided imagery mHealth app has the potential to address multiple behaviors. Future research should consider different methods to improve retention and assess efficacy.

[What is new in the epidemiology of lung cancer: non-smokers, women and the role of cannabis?].

PubMed

Quoix, Elisabeth

2009-09-20

Lung cancer is in France, like in other countries, the first cause of death by cancer in men. It has become the third one in women in a few years span. If smoking is the main cause of lung cancer, other causes have been quite neglected for years such as occupational risk mainly asbestos exposure. Lung cancer in non-smokers has increased during the last years. This may be a real increase or the consequence of ageing of the general population with increased incidence of lung cancer rather due to age than to tobacco. The considerable increase in women's incidence of lung cancer is partly due to the development of smoking habits since 1960 in France. The possibility of an increased suceptibility to tobacco smoke in women is biologically plausible but still very controversial. The role of cannabis smoke is also controversial since it is very difficult to isolate the effects of cannabis which is in the majority of cases smoked with tobacco. However, recent studies are in favor of an independent role of cannabis in the development of lung cancers.

In a clinical study, changes in 14 biomarkers of exposures (BOEs) from 10 tobacco smoke constituents and mutagens detected by the urine mutagenicity test were investigated using a non-combustion inhaler type of tobacco product (NCIT) by switching from a conventional cigarette. This study was conducted in 80 Japanese healthy adult males with a 4-week residential, controlled, open-label, parallel group design. After randomization, 40 smokers used NCIT with approximately 750 aspirations, other 20 smokers smoked approximately 20 pieces of an assigned 1-mg ISO tar conventional cigarette (CC1) every day. Twenty non-smokers (NS) did not use any tobacco product. Under this study condition, switching from cigarette to NCIT showed significant reduction in all BOEs measured. On day 29, the levels of these BOEs were almost the same as those in the NS group, except BOEs of nicotine and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK). This suggested that the exposure to 8 constituents and mutagens in the NCIT group was similar to that in the NS group, while the exposure to nicotine was higher. Although the precise exposure level to NNK was not estimated because of the long half-life of its BOE, it would be substantially lower in the NCIT group than in the CC1 group.

Background Vibration response imaging (VRI) is a new technology for lung imaging. Active smokers and non-smokers show differences in VRI findings, but no data are available for passive smokers. The aim of this study was to evaluate the use of VRI and to assess the differences in VRI findings among non-smokers, active smokers, and passive smokers. Material/Methods Healthy subjects (n=165: 63 non-smokers, 56 active smokers, and 46 passive smokers) with normal lung function were enrolled. Medical history, physical examination, lung function test, and VRI were performed for all subjects. Correlation between smoking index and VRI scores (VRIS) were performed. Results VRI images showed progressive and regressive stages representing the inspiratory and expiratory phases bilaterally in a vertical and synchronized manner in non-smokers. Vibration energy curves with low expiratory phase and plateau were present in 6.35% and 3.17%, respectively, of healthy non-smokers, 41.07% and 28.60% of smokers, and 39.13% and 30.43% of passive smokers, respectively. The massive energy peak in the non-smokers, smokers, and passive-smokers was 1.77±0.27, 1.57±0.29, and 1.66±0.33, respectively (all P<0.001). A weak but positive correlation was observed between VRIS and smoking index. Conclusions VRI can intuitively show the differences between non-smokers and smokers. VRI revealed that passive smoking can also harm the lungs. VRI could be used to visually persuade smokers to give up smoking. PMID:26212715

Diet and food intake play an important role in the development of osteoporosis. However, apart from calcium and vitamin D, how nutrients affect bone status is not fully understood. The purpose of this study was to determine cross-sectional and longitudinal associations between dietary intake and bone mineral density (BMD) in Japanese postmenopausal women. This 5-year cohort study included 600 community-dwelling women aged 55-74 years at baseline in 2005. Information on demographics, nutrition, and lifestyle was obtained through interviews, and nutritional and dietary intake was assessed using a validated food frequency questionnaire. BMD measurements were performed by dual energy X-ray absorptiometry. In 2010, 498 women underwent follow-up BMD examinations. Multiple linear regression analysis was performed to determine associations of predictor variables with BMD, adjusting for confounders. In cross-sectional analyses, coffee or black tea consumption was positively associated with lumbar spine (P = 0.004) and total hip (P = 0.003) BMD, and alcohol intake was positively associated with femoral neck (P = 0.005) and total hip (P = 0.001) BMD. In longitudinal analyses, vitamin K (P = 0.028) and natto (fermented soybeans) (P = 0.023) were positively associated with lumbar spine BMD, and meat or meat product consumption was inversely associated with total hip (P = 0.047) BMD. In conclusion, dietary factors other than calcium and vitamin D intake are predictors of bone mass and bone loss in Japanese postmenopausal women. In particular, natto intake is recommended for preventing postmenopausal bone loss on the basis of current evidence.

Participants were randomized to one of six medication treatment conditions in a randomized double-blind, placebo-controlled clinical trial. All participants received six individual counseling sessions. Community-based smokers in two communities in Wisconsin, USA. A total of 1504 adult smokers who smoked at least 10 cigarettes per day during the past 6 months and reported being motivated to quit smoking. The analysis sample comprised 1439 participants: 814 white non-menthol smokers, 439 white menthol smokers and 186 African American (AA) menthol smokers. There were too few AA non-menthol smokers (n = 16) to be included in the analyses. Nicotine lozenge, nicotine patch, bupropion sustained release, nicotine patch + nicotine lozenge, bupropion + nicotine lozenge and placebo. Biochemically confirmed 7-day point-prevalence abstinence assessed at 4, 8 and 26 weeks post-quit. In longitudinal abstinence analyses (generalized estimating equations) controlling for cessation treatment, menthol smoking was associated with reduced likelihood of smoking cessation success relative to non-menthol smoking [model-based estimates of abstinence = 31 versus 38%, respectively; odds ratio (OR) = 0.71, 95% confidence interval (CI) = 0.59, 0.86]. In addition, among menthol smokers, AA women were at especially high risk of cessation failure relative to white women (estimated abstinence = 17 versus 35%, respectively; OR = 2.63, 95% CI = 1.75, 3.96; estimated abstinence rates for AA males and white males were both 30%, OR = 1.06, 95% CI = 0.60, 1.66). In the United States, smoking menthol cigarettes appears to be associated with reduced cessation success compared with non-menthol smoking, especially in African American females. © 2014 Society for the Study of Addiction.

Rationale Chronic obstructive pulmonary disease (COPD) is often associated with age-related systemic abnormalities that adversely affect the prognosis. Whether these manifestations are linked to the lung alterations or are independent complications of smoking remains unclear. Objectives To look for aging-related systemic manifestations and telomere shortening in COPD patients and smokers with minor lung destruction responsible for a decline in the diffusing capacity for carbon monoxide (DLCO) corrected for alveolar volume (KCO). Methods Cross-sectional study in 301 individuals (100 with COPD, 100 smokers without COPD, and 101 nonsmokers without COPD). Measurements and Main Results Compared to control smokers, patients with COPD had higher aortic pulse-wave velocity (PWV), lower bone mineral density (BMD) and appendicular skeletal muscle mass index (ASMMI), and shorter telomere length (TL). Insulin resistance (HOMA-IR) and glomerular filtration rate (GFR) were similar between control smokers and COPD patients. Smokers did not differ from nonsmokers for any of these parameters. However, smokers with normal spirometry but low KCO had lower ASMMI values compared to those with normal KCO. Moreover, female smokers with low KCO, had lower BMD and shorter TL compared to those with normal KCO. Conclusions Aging-related abnormalities in patients with COPD are also found in smokers with minor lung dysfunction manifesting as a KCO decrease. Decreased KCO might be useful, particularly among women, for identifying smokers at high risk for aging-related systemic manifestations and telomere shortening. PMID:25785739

In spite of the importance of a multifactorial approach to preventing cardiovascular disease in smokers, most information on the combined adverse effects of smoking and hypertension or high serum cholesterol on cardiovascular disease has been derived from Western populations, and coronary heart disease was often used as the only endpoint. Therefore, the present large-scale pooled analysis attempted to provide reliable information on the adverse effects of the coexistence of smoking and hypertension or high serum cholesterol on the risk of mortality from coronary heart disease and stroke in both, individuals and the entire population in Japan. A total of 27,385 male and 39,207 female participants aged 40-89 years were enrolled from 10 well-qualified Japanese cohort studies with a mean follow-up of 10.1 years. Hazard ratios and their corresponding 95% confidence intervals in smokers who had hypertension or high serum cholesterol were estimated for men and women separately using a Cox proportional hazards regression model that included age, body mass index, cohort and either serum total cholesterol or systolic blood pressure as covariates. Fractions of deaths attributable to the coexistence of these risk factors were also calculated. The multivariate-adjusted hazard ratios in male and female current smokers with hypertension, compared with those with neither factor were 2.57 (95% confidence intervals, 1.51-4.38) and 6.14 (3.49-10.79) for coronary heart disease, and 3.28 (1.89-5.71) and 1.61 (0.81-3.18) for cerebral infarction, respectively. The fractions of deaths attributable to the coexistence of current smoking and hypertension in men and women were 24.6 and 9.6% for coronary heart disease and 28.1 and 2.0% for cerebral infarction, respectively. Smokers with high serum cholesterol were broadly comparable to hypertensive smokers only with respect to coronary mortality risk; the hazard ratios, compared with those with neither factor were 4.19 (2.33-7.53) for men and

Nicotine replacement therapy (NRT) is used by smokers wanting to reduce their smoking and to quit. However, there are very little data on nicotine intake associated with NRT use in representative population samples. This study aimed to provide estimates for NRT use and associated nicotine exposure among smokers, recent and longer-term ex-smokers in England, a country with a permissive regulatory regime for nicotine substitution. In the Smoking Toolkit Study, a monthly series of representative household surveys of adults aged 16+ in England, current and recent ex-smokers who agreed to be re-contacted were followed up 6 months later and standard socio-demographic and smoking characteristics assessed (N = 5,467, response rate 25.1%). A random sub-sample (N = 1,614; 29.5%) also provided saliva, analysed for cotinine. The sample followed up was broadly representative of the original sample. At follow-up, 11.8% (95%CI 10.9-12.8, N = 565) of current smokers, 34.8% (95%CI 28.9-41.3, N = 77) of recent (≤ 3 months) ex-smokers, and 7.8% (95%CI 5.6-10.6, N = 36) of longer-term (> 3 months) ex-smokers reported using NRT. Smokers who used NRT had similar saliva cotinine concentrations to smokers who did not use NRT (mean ± sd  = 356.0 ± 198.6 ng/ml vs. 313.1 ± 178.4 ng/ml). Recent ex-smokers who used NRT had levels that were somewhat lower, but not significantly so, than current smokers (216.7 ± 179.3 ng/ml). Longer-term ex-smokers using NRT had still lower levels (157.3 ± 227.1 ng/ml), which differed significantly from smokers using NRT (p = 0.024). Concurrent use of nicotine replacement therapy while smoking is relatively uncommon and is not associated with higher levels of nicotine intake. Among ex-smokers, NRT use is common in the short but not longer-term and among longer-term users is associated with lower nicotine intake than in smokers.

It has been suggested that extrinsic skin ageing manifests differently in Caucasians versus East Asians. In particular, from previous studies it was concluded that Caucasians are more prone to develop wrinkles, whereas pigment spot formation is the hallmark of extrinsic skin ageing in East Asians. However, these assumptions are based on a very limited number of studies which did not include different East Asian populations. We here compare the manifestation of extrinsic skin ageing signs in German, Japanese and Chinese women by specifically elucidating the age and anatomical site dependence of any potential ethnic difference. In the present study, we assessed skin ageing in N=902 German, N=165 Japanese and N=1260 Chinese women ranging from 30 to 90 years by means of SCINEXA™. Linear regression analysis was used to test for ethnic differences and their age and site dependence adjusted for educational level, sun exposure, smoking and sun protection behaviours. Pigment spots and wrinkles on the face were present among all three ethnic groups and differences were influenced by age and anatomical sites independently of further influencing factors. Pigment spots on the forehead were most pronounced over the whole age range in Chinese and German women and least developed in Japanese. Pigment spots on cheeks were a typical extrinsic skin an ageing sign in the two East Asian populations in all age groups. However, in older German women they reach the same level as observed in the two East Asian populations. In contrast, pigment spots on arms and hands were significantly more pronounced in German women ≥45years of age. Wrinkles were not exclusively a skin an ageing sign of German women, but were also very pronounced in Chinese women on forehead, between the eyebrows and in the crow's feet area. These results corroborate the previous notion that the occurrence of pigments spots and wrinkles is different between Caucasians and East Asians. In addition, this study shows

The use of electronic cigarettes (EC) has risen exponentially over the past decade, including among never smokers, and ECs are now the most popular tobacco product among teenagers in the US. While, EC manufacturers utilize numerous marketing strategies to target both smokers and non-smokers, it is unclear how perceptions and behaviors differ between these two groups. We conducted a survey of 320 adults either via online surveys or in Baltimore vape shops to determine demographics, behaviors, perceptions, and motivations underlying use of ECs. Our survey respondents were predominantly young, Caucasian males, 74% of whom identified themselves as former smokers, while 20% identified as current smokers and 6% were never smokers. Former smokers reported a longer history of EC use and higher nicotine concentrations than current smokers. For former and current smokers, the primary motivation for EC use was assistance to quit smoking, and nearly half indicated that they plan to reduce their nicotine concentration and eventually quit using ECs. Among former smokers, self-reports on use and measures of dependence were consistent with nicotine replacement as their primary motivation. The majority of former and current smokers also reported that their respiratory health had improved as a result of EC use, although this effect was stronger for former smokers. Never smokers reported less frequent EC use and dependence compared to former and current smokers. Their motivations for use were more commonly for enjoyment and popularity, and they displayed a reduced desire to eventually quit using ECs. These responses provide insight into the underlying thoughts and behaviors of smoking and non-smoking EC users and also suggest that never smoking EC users are an emerging demographic with different motivations and perceptions than those of current and former smokers.

Smoking in women is a well-recognized public health problem. In many developed countries, cigarette smoking is now the single most important preventable cause of premature death in women. There are relatively few data on the epidemiology of cigarette smoking in Asian women, and this study examined the prevalence of and factors predisposing Chinese women to smoke cigarettes in Hong Kong. A territory-wide random telephone survey of 26,716 households in Hong Kong was conducted. A total of 1064 current smokers and 291 ex-smokers were identified in these household, and in-depth interviews of 791 current smokers, 221 ex-smokers, and 1012 controls were conducted. The prevalence of cigarette smoking was 4.5% in women who were 25 years or younger, 2.6% in women aged 46-65 years, and 2.2% in women aged 65 years or older. Sixty-four percent of current smokers started when they were 19 years or younger. The main reasons for the initiation of cigarette smoking were the influence of friends, curiosity, feeling bored, or being idle. Current smokers and ex-smokers tended to have positive images of women who smoked. The following risk factors were found to be significant for cigarette smoking: less than university education, unemployment, being divorced, having a husband who smoked, and a low score on the perceived harms of cigarette smoking. Cigarette smoking is more prevalent in younger women in Hong Kong; and psychosocial issues should be addressed to prevent future epidemics.

Successful smoking cessation appears to be facilitated by identity change, that is, when quitting or nonsmoking becomes part of smokers' and ex-smokers' self-concepts. The current longitudinal study is the first to examine how identity changes over time among smokers and ex-smokers and whether this can be predicted by socioeconomic status (SES) and psychosocial factors (i.e., attitude, perceived health damage, social norms, stigma, acceptance, self-evaluative emotions, health worries, expected social support). We examined identification with smoking (i.e., smoker self-identity) and quitting (i.e., quitter self-identity) among a large sample of smokers (n = 742) and ex-smokers (n = 201) in a cohort study with yearly measurements between 2009 and 2014. Latent growth curve modeling was used as an advanced statistical technique. As hypothesized, smokers perceived themselves more as smokers and less as quitters than do ex-smokers, and identification with smoking increased over time among smokers and decreased among ex-smokers. Furthermore, psychosocial factors predicted baseline identity and identity development. Socioeconomic status (SES) was particularly important. Specifically, lower SES smokers and lower SES ex-smokers identified more strongly with smoking, and smoker and quitter identities were more resistant to change among lower SES groups. Moreover, stronger proquitting social norms were associated with increasing quitter identities over time among smokers and ex-smokers and with decreasing smoker identities among ex-smokers. Predictors of identity differed between smokers and ex-smokers. Results suggest that SES and proquitting social norms should be taken into account when developing ways to facilitate identity change and, thereby, successful smoking cessation.

Cigarette smokers, never-smokers, and transitions: implications for successful aging.

One of the social identities held by people is defined by whether or not they smoke cigarettes. Although this identity can and does change for many people over the course of their lives, most research has not examined the effects of transitioning from a smoker to a non-smoker. Using a life span perspective, our analyses contrasted the extent to which successful aging is experienced by: (1) persons who ever smoked and those who never smoked; (2) former smokers and current smokers; and (3) persons who transitioned from being a smoker to being a non-smoker at different ages. Using data from a random sample of 5688 persons between the ages of 50 and 74 living in New Jersey, we found that persons who never smoked were most likely to age successfully; there were no differences in patterns of successful aging when all former smokers were compared to current smokers; and persons who quit smoking before age 30 experienced modest benefits compared with those who continued to smoke.

Much effort has been devoted to examining the differences in postcessation affective experience between smoking abstainers and relapsers. However, little attention has been given to the affective changes of smokers who, despite their motivation to quit, fail to achieve even a brief period of abstinence. Using affect-modulated startle response and self-report questionnaires, we measured the postcessation affective changes of 115 smokers (60 men, 55 women) who participated in a laboratory investigation of affective reactivity during smoking cessation. Among our participants, 34 were abstainers (16 men, 18 women), 16 were never-quitters (8 men, 8 women), 19 were relapsers (8 men, 11 women), and 46 were controls (28 men, 18 women). We found a significant Stimulus Valence × Session × Group interaction effect on startle responses, which suggested that while abstainers, relapsers, and control exhibited the prototypical affect-modulated startle response across postcessation sessions, never-quitters displayed an atypical response pattern in which emotional pictures no longer modulated the startle response. Never-quitters also reported increasingly higher negative and lower positive affect across postcessation sessions. Using affect-modulated startle response and self-report questionnaires, this study found a significant difference in the affective reactivity between smokers who could and smokers who could not establish an initial abstinence of 24 hours.

Telling her story: narrating a Japanese lesbian community.

Welker, James

2010-01-01

This article explores queer Japanese women's narratives of their own histories and the history of the "Japanese lesbian community," which has been constructed as a space outside the heterosexual mainstream, a space where queer women can find at least temporary refuge. It begins with the acknowledgment that the evolution and the shape of the community, along with the identities of the women who comprise it, are shifting and contested. This article specifically looks at the long history of the lesbian bar scene as well as more recent history of lesbian dance parties; the early role of lesbian feminism and activism; lesbian community-based and commercial publications, paying special attention to the critical role translation has played in Japanese lesbian discourse and the construction of multiple lesbian identities; and, finally, lesbian, gay, bisexual, and transgender (LGBT) pride events and film festivals, through which the larger LGBT community has been gaining increasing visibility. This article argues that while some of the building blocks of the community are borrowed, from the "West" as well as from the Japanese gay community, there has also been creative translation, adaptation, and resistance to these imports. The resulting Japanese lesbian community is a complex and local construct, an innovative bricolage firmly sited in Japan.

Background Previous studies have shown that a diet with a high-glycemic index is associated with good sleep quality. Therefore, we investigated the association of sleep quality with the intake of 3 common starchy foods with different glycemic indexes–rice, bread, and noodles–as well as the dietary glycemic index in a Japanese population. Methods The participants were 1,848 men and women between 20 and 60 years of age. Rice, bread, and noodle consumption was evaluated using a self-administered diet history questionnaire. Sleep quality was evaluated by using the Japanese version of the Pittsburgh Sleep Quality Index, and a global score >5.5 was considered to indicate poor sleep. Results Multivariate-adjusted odds ratios (95% confidence intervals) for poor sleep across the quintiles of rice consumption were 1.00 (reference), 0.68 (0.49–0.93), 0.61 (0.43–0.85), 0.59 (0.42–0.85), and 0.54 (0.37–0.81) (p for trend = 0.015); those for the quintiles of noodle consumption were 1.00 (reference), 1.25 (0.90–1.74), 1.05 (0.75–1.47), 1.31 (0.94–1.82), and 1.82 (1.31–2.51) (p for trend = 0.002). Bread intake was not associated with sleep quality. A higher dietary glycemic index was significantly associated with a lower risk of poor sleep (p for trend = 0.020). Conclusion A high dietary glycemic index and high rice consumption are significantly associated with good sleep in Japanese men and women, whereas bread intake is not associated with sleep quality and noodle consumption is associated with poor sleep. The different associations of these starchy foods with sleep quality might be attributable to the different glycemic index of each food. PMID:25127476

To examine the relationship between the presence of smokers in the workplace and smokers in the home and current smoking status among employed men and women. Analysis of data from the second wave of the nationally representative Survey of Midlife Development in the United States (2004-2006). Sample of 627 currently employed men and women, aged 34 to 82 (M = 51), who had been regular cigarette smokers at some time. Survey items indexing presence of smokers in the respondents' immediate work area and home and their current smoking status. Multiple logistic regression analyses, controlling for age, gender, education, race, and job type. Examined together, smokers in the workplace (OR = 2.83) and smokers in the home (OR = 6.09) were uniquely associated with current smoking status. Moreover, smokers in the home reduced the association between smokers in the workplace and current smoking. The presence of smokers in the workplace was associated with a more than fourfold increase in current smoking among respondents with no smokers in the home, but was unrelated to current smoking among respondents with smokers in the home. Failure to consider the presence of smokers in the home significantly limits the potential impact of workplace smoking interventions.

To identify the risk factors associated with abnormal glucose tolerance (AGT) on the first postpartum oral glucose tolerance test (OGTT) among Japanese women with gestational diabetes (GDM). In a retrospective study, data were analyzed from women with GDM who underwent their first postpartum OGTT 6-8weeks post partum at a center in Omura, Japan, between January 1, 2007, and December 31, 2011. Women with diabetes or impaired glucose tolerance were deemed to have postpartum AGT. The association between postpartum AGT and various risk factors was analyzed. Among 169 women who underwent a postpartum OGTT, 58 (34.3%) had AGT. The significant risk factors associated with postpartum AGT in univariate analysis were pre-pregnancy body mass index (P=0.096), 1-hour plasma glucose (P=0.006), hemoglobin A1c (P<0.001), insulinogenic index (P=0.05), an insulinogenic index of less than 0.4 (P=0.006), and insulin therapy during pregnancy (P<0.001). Independent risk factors identified by multivariate logistic regression models were insulinogenic index (odds ratio [OR] 0.10, 95% confidence interval [CI] 0.01-0.74; P=0.002), an insulinogenic index of less than 0.4 (OR 5.70, 95% CI 1.69-21.66; P=0.005), and insulin therapy during pregnancy (OR 3.43, 95% CI 1.03-12.55; P=0.044). Among Japanese women with GDM, a lower insulinogenic index and use of insulin therapy during pregnancy are associated with early postpartum AGT.

Community members are occasionally polled about tobacco control policies, but are rarely given opportunities to elaborate on their views. We examined laypeople's conversations to understand how 11 regulatory options were supported or opposed in interactions. Qualitative design; purposive quota sampling; data collection via focus groups. Three locations in Sydney, Australia. 63 smokers and 75 non-smokers, men and women, from three age groups (18-24, 35-44, 55-64 years), recruited primarily via telephone. Semi-structured question route; data managed in NVivo; responses compared between groups. Laypeople rejected some regulatory proposals and certain arguments about taxation and the cost of cessation treatments. Protecting children and hypothecating tobacco excise for health education and care were highly acceptable. Plain packaging, banning retail displays and youth smoking prevention received qualified support. Bans on political donations from tobacco corporations were popular in principle but considered logistically fraught. Smokers asked for better cessation assistance and were curious about cigarette ingredients. Justice was an important evaluative principle. Support was often conditional and unresolved arguments frequent. We present both sides of these conflicts and the ways in which policies were legitimised or de-legitimised in conversation. Simple measures of agreement used in polls may obscure the complexity of community responses to tobacco policy. Support was frequently present but contested; some arguments that seem self-evident to advocates were not so to participants. The detailed understanding of laypeople's responses provided through qualitative methods may help frame proposals and arguments to meet concerns about justice, effectiveness and feasibility.

To evaluate the level of cardiovascular risk in smokers seenin Primary Care clinics. Epidemiologic, cross-sectional and multicentre study. Primary Care. Every investigator included 4 consecutive patients (3 smokers, 1 non-smoker) aged 35-50 years, who came to the clinic for any reason. A total of 2,184 patients were included; 2,124 (1,597 smokers; 527 non-smokers) were evaluated and 60 patients were excluded because they did not meet with selection criteria. The 10-year risk of suffering from a fatal cardiovascular disease (CVDR) was calculated according to the SCORE (Systematic Coronary Risk Evaluation) model. The 10-year lethal CVR according SCORE model, was classified as: very high (> 15%), high (10-14%), slightly high (5-9%), average (3-4%), low (2%), very low (1%) and negligible (< 1%). A logistical regression model was used to estimate the relationship between smoking and prior cardiovascular events. 10-year fatal CVDR according to the SCORE model was significantly higher in smokers (40±5.3) vs. non-smokers (1.9±2.5) (P<.0001). low (< 3%) [78.0% non-smokers vs. 60.7% smokers (P<.0001)]; intermediate (3-5%) [11.1% non-smokers vs. 12.6% smokers (P<.001)]; high (> 5%) [10.9% non-smokers vs. 26.7% smokers (P<.001)]. The logistical regression model showed that non-smokers vs. smokers had less probability of suffering myocardial infarction (OR 0.3; 95% confidence interval (95% CI): 0.1-0.8; P<.0001), peripheral vascular disease (OR 0.6; 95% CI: 0.4-1.0; P=.0180) and chronic obstructive lung disease (OR 0.18; 95% CI: 0.1-0.2; P=.0507). Smoking is related to a high risk of fatal cardiovascular disease. Active promotion in Primary Care clinics of measures aimed at reducing the prevalence of the smoking habit would lead to a lowering of cardiovascular morbidity and mortality.

Objective: To assess the relation between demographic factors and film smoking stereotypes in adolescents and the potential influence of smoker stereotypes on smoking susceptibility. Design: A cross sectional questionnaire survey of school students (n = 3041) aged 12–13 and 16–17 years who were asked to describe the personal characteristics of female and male smokers in films. Setting: 15 primary or intermediate schools and 10 secondary schools in Auckland, New Zealand. Results: Appraisals of smokers in film were strongly influenced by age and sex with younger adolescents and males more likely to see female smokers as sexy, intelligent and healthy whereas older students and females more often appraised female smokers as stressed bored and depressed. Overall, image stereotypes (sexy, stylish) were more likely to be significantly associated with smoking susceptibility than emotional sensitivity stereotypes (stressed, depressed etc). Conclusions: Adolescents differ significantly in their appraisal of smokers in films; however, image based stereotypes, rather than emotional sensitivity stereotypes, are significantly associated with smoking susceptibility.

Increased anxiety correlates with increased complications after acute myocardial infarction. Anxiety levels and use of anxiolytic agents have not been compared between smokers and nonsmokers hospitalized because of acute myocardial infarction. To compare anxiety level, sociodemographic factors, and clinical variables between smokers and nonsmokers hospitalized with acute myocardial infarction and to examine predictors of use of beta-blockers and anxiolytic agents among smokers and nonsmokers. Secondary data analysis of a prospective multisite study on anxiety in 181 smokers and 351 nonsmokers with acute myocardial infarction. Anxiety was measured by using the State Trait Anxiety Inventory and the anxiety subscale of the Basic Symptom Inventory within 72 hours of admission. Smokers reported higher anxiety levels than nonsmokers reported on both anxiety scales. Female smokers reported the highest anxiety and peak pain levels of all, yet women were the least likely to receive anxiolytic agents. Smoking status was not a predictor for anxiety level when sex, peak pain, use of beta-blockers in the hospital, and age were controlled for. However, smokers were twice as likely as nonsmokers to receive an anxiolytic agent and 60% more likely to receive a beta-blocker in the emergency department, and smokers were 80% more likely than nonsmokers to receive an anxiolytic agent during hospitalization when these variables were controlled. Older female smokers are at risk for complications because they are older than their male counterparts and less likely to receive beta-blockers and antianxiety medications in the emergency department.

The International Clearinghouse for Birth Defects, Surveillance and Research reports a rise in the prevalence rate of spina bifida in Japan. We determined first-trimester folate status of Hokkaido women and identified potential predictors. Participants were 15 266 pregnant women of the Hokkaido Study on Environment and Children's Health Cohort. Data were extracted from self-reported questionnaires and biochemical assay results. Demographic determinants of low folate status were younger maternal age (adjusted OR (AOR) 1·48; 95 % CI 1·32, 1·66), lower educational level (AOR 1·27; 95 % CI 1·17, 1·39) and lower annual income (AOR 1·11; 95 % CI 1·01, 1·22). Plasma cotinine concentrations of 1·19-65·21 nmol/l increased the risk of low folate status (AOR 1·20; 95 % CI 1·10, 1·31) and concentrations >65·21 nmol/l further increased the risk (AOR 1·91; 95 % CI 1·70, 2·14). The most favourable predictor was use of folic acid (FA) supplements (AOR 0·19; 95 % CI 0·17, 0·22). Certain socio-demographic factors influence folate status among pregnant Japanese women. Modifiable negative and positive predictors were active and passive tobacco smoking and use of FA supplements. Avoiding both active and passive tobacco smoking and using FA supplements could improve the folate status of Japanese women.

The association between dietary total antioxidant capacity (TAC) from different assays and serum C-reactive protein (CRP) has not been assessed in non-Western populations. We examined the association between dietary TAC and serum CRP concentration in young Japanese women using different four TAC assays. The subjects were 443 young Japanese women aged 18-22 years. Dietary TAC was assessed with a self-administered diet history questionnaire and the TAC value of each food using the following four assays: ferric reducing ability of plasma (FRAP); oxygen radical absorbance capacity (ORAC); Trolox equivalent antioxidant capacity (TEAC); and total radical-trapping antioxidant parameter (TRAP). Serum CRP concentrations were measured by highly sensitive nephelometry. The major contributor to dietary TAC was green, barley, and oolong tea (FRAP: 53%, ORAC: 45%, TEAC: 36%, and TRAP: 44%). The prevalence of elevated CRP concentrations (≥ 1 mg/L) was 5.6%. TAC from FRAP was inversely associated with serum CRP concentrations (adjusted odds ratio [OR] for elevated CRP concentration in high [compared with low] dietary TAC group: 0.39 [95% confidence interval (CI): 0.16-0.98]; P = 0.04). TAC from ORAC was inversely associated with CRP, although the association was not significant (OR: 0.48 [95% CI: 0.20-1.14]; P = 0.10). TAC from TEAC was inversely associated with CRP (OR: 0.32 [95% CI: 0.12-0.82]; P = 0.02), as was TAC from TRAP (OR: 0.31 [95% CI: 0.12-0.81]; P = 0.02). Dietary TAC was inversely associated with serum CRP concentration in young Japanese women regardless of assay. Further studies are needed in other populations to confirm these results.

The Japanese Orthopaedic Association proposed a concept called locomotive syndrome (LS) to identify middle-aged and older adults at high risk of requiring health care services because of problems with locomotion. It is important to identify factors associated with the development of LS. Physical performance measures such as walking speed and standing balance are highly predictive of subsequent disability and mortality in older adults. However, there is little evidence about the relationship between physical performance measures and LS. To determine the physical performance measures associated with LS, the threshold values for discriminating individuals with and without LS, and the odds ratio of LS according to performance greater than or less than these thresholds in middle-aged and older Japanese women. Participants were 126 Japanese women (mean age = 61.8 years). Locomotive syndrome was defined as a score of 16 or more on the 25-question Geriatric Locomotive Function Scale. Physical performance was evaluated using grip strength, unipedal stance time with eyes open, seated toe-touch, and normal and fast 6-m walk time (6 MWT). Variables were compared between LS and non-LS groups. Fourteen participants (11.1%) were classed as having LS. Unipedal stance time, normal 6 MWT, and fast 6 MWT were significantly different between the 2 groups. The LS group had a shorter unipedal stance time and a longer normal and fast 6 MWT than the non-LS group. For these 3 variables, the area under the receiver operating characteristic curve was greater than 0.7, and the threshold for discriminating the non-LS and LS groups was 15 s for unipedal stance time, 4.8 s for normal 6 MWT and 3.6 s for fast 6 MWT. These variables were entered into a multiple logistic regression analysis, which indicated that unipedal stance time less than 15 s was significantly related to LS (odds ratio = 8.46; P < .01). Unipedal stance time was the physical performance measure that was most strongly associated

Studies from Western countries suggest that smokers tend to display greater abdominal obesity than non-smokers, despite showing lower weight. Whether this holds true in a leaner population requires clarification. Using indices of abdominal obesity including visceral adipose tissue, we examined whether lifetime cigarette smoking is associated with unfavorable fat distribution among Japanese men. From 2006 to 2008, we conducted a cross-sectional investigation of a community-based sample of Japanese men at 40-64 years old, free of cardiovascular diseases and cancer. Areas of abdominal visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) were calculated using computed tomography. We divided participants into four groups: never-smokers; and tertiles of pack-years of smoking among ever-smokers. Using multivariable linear regression, we calculated adjusted means of obesity indices (VAT, SAT, VAT-SAT ratio [VSR], and waist-hip ratio [WHR]) for each group, and mean differences between consecutive groups. We analyzed 513 men (median age, 58.2 years; current smokers, 40.1%). Two-thirds showed body mass index (BMI) < 25 kg/m(2) (median, 23.5 kg/m(2)). Overall, greater lifetime smoking group was associated with greater WHR and VSR. On average, one higher smoking group was associated with 0.005 higher WHR (95% CI, 0.001-0.008; P = 0.005) and 0.041 greater VSR (95% CI, 0.009-0.073; P = 0.012) after adjustment for potential confounders, including BMI. In this sample of relatively lean Japanese men, greater lifetime smoking was associated with a metabolically more adverse fat distribution. Although smoking is commonly associated with lower BMI, minimizing the amount of lifetime smoking should be advocated.

Exposure to food service establishments is considered to encourage consumption and contribute to poorer diet quality, and hence adverse health profiles. However, empirical verification of these links remains rare, particularly in young adults and non-Western populations. The objective of this cross-sectional study was to test the hypothesis that neighborhood restaurant availability and frequency of eating out are associated with unfavorable patterns of dietary intake and thus possibly higher body mass index (BMI) and waist circumference in young Japanese women. The subjects were 989 female Japanese dietetic students 18 to 22 y of age. Dietary intake and frequency of eating out (i.e., consumption of commercially prepared meals) during the preceding month were assessed using a comprehensive, self-administered diet history questionnaire. Neighborhood restaurant availability was defined as the number of restaurants within a 0.5-mile (0.8-km) radius of residence (i.e., full-service restaurants, limited-service restaurants, and cafeterias). Increasing frequency of eating out was associated with higher intake of meat, confectionery and bread, and dietary fat, lower intake of fruit and vegetables, rice, and dietary fiber, and higher dietary energy density. However, neighborhood restaurant availability was not associated with either the frequency of eating out or any of the dietary variables examined. Further, frequency of eating out and neighborhood restaurant availability were not associated with BMI or waist circumference. In conclusion, although frequency of eating out was positively associated with unfavorable dietary intake patterns in a group of young Japanese women, neighborhood restaurant availability was not associated with frequency of eating out or dietary intake.

Prior to and during World War II, thousands of girls and young women were abducted from Korea and forced into sexual slavery by the Japanese government. Termed comfort women, these girls and young women suffered extreme sexual, physical, and emotional abuse and trauma. Research on this group is not well-developed and people know little of the impact of this early life trauma on the lives of these women who are now in later life. Using snowball sampling, 16 older adult survivors of the comfort women system participated in semistructured qualitative interviews. Thematic analysis was conducted to gain an understanding of the trauma that these women suffered and how it impacted their lives. Results revealed the depths of the abuse these women suffered, including repeated rapes, physical beatings, humiliation, forced surgery and sterilization, and social exclusion. These early traumatic experiences appeared to reverberate throughout their lives in their family relations, their inability to marry and to conceive children, and their emotional and physical well-being throughout the life course and into later life. The experiences of these survivors illustrate the lasting impact of early-life trauma and can guide interventions with current survivors of sexual abuse or trafficking.

To explore what it is like to be a pregnant smoker in Sunderland and to inform the development of a Smoking Cessation Programme; to use qualitative techniques to develop a cessation programme tailored to pregnant smokers. The intervention follows years of social marketing research and development in Sunderland, Wearside, UK. Information derived from nine focus groups (mainly with women from deprived areas, social class C2D and E) provided insights into the issues facing smoking pregnant women. This information was then used to overcome barriers to smoking cessation using the principles of social marketing. The number of women recruited into a specially designed smoking cessation support initiative was compared with women recruited into comparable groups in the North East. Recruitment of pregnant (and non-pregnant) smokers to the new NHS smoking cessation programme in Sunderland has increased during the intervention phase compared with neighbouring Primary Care Trust areas (in which different smoking cessation interventions targeted at pregnant women were being undertaken). This innovative intervention has been successful in generating ideas, guiding development of a customer-friendly service and encouraging women to come forward for smoking cessation support during their pregnancy. The target population have welcomed the approach, and health professionals have enjoyed and benefited from the role play with professional actors.

Occupational position is one of the determinants of psychological health, but this association may differ for men and women depending on the social context. In contemporary Japanese society, occupational gender segregation persists despite increased numbers of women participating in the labour market, which may contribute to gender specific patterns in the prevalence of poor psychological health. The present study examined gender specific associations between occupational position and psychological health in Japan, and the potential mediating effects of job control and effort-reward imbalance in these associations. We used data obtained from 7123 men and 2222 women, aged between 18 and 65 years, who participated in an occupational cohort study, the Japanese Study of Health, Occupation, and Psychosocial Factors Related Equity (J-HOPE), between 2011 and 2012. We used logistic regression to examine the association between occupational position and poor psychological health, adjusted for age, working hours, household income and education, as well as psychosocial work characteristics (job control and effort-reward imbalance). The prevalence of poor psychological health increased from manual/service occupations (23%) to professionals/managers (38%) among women, while it did not vary by occupational position among men. In women, the significant association between occupational position and psychological health was not explained by job control, but was attenuated by effort-reward imbalance. Our findings suggest that Japanese women in more advantaged occupational positions are likely to be at a greater risk for poor psychological health due to higher levels of effort-reward imbalance at work.

Background Bacterial vaginosis (BV), the etiology of which is still uncertain, increases the risk of preterm birth. Recent PCR-based studies suggested that BV is associated with complex vaginal bacterial communities, including many newly recognized bacterial species in non-pregnant women. Methods To examine whether these bacteria are also involved in BV in pregnant Japanese women, vaginal fluid samples were taken from 132 women, classified as normal (n = 98), intermediate (n = 21), or BV (n = 13) using the Nugent gram stain criteria, and studied. DNA extracted from these samples was analyzed for bacterial sequences of any Lactobacillus, four Lactobacillus species, and four BV-related bacteria by PCR with primers for 16S ribosomal DNA including a universal Lactobacillus primer, Lactobacillus species-specific primers for L. crispatus, L. jensenii, L. gasseri, and L. iners, and BV-related bacterium-specific primers for BVAB2, Megasphaera, Leptotrichia, and Eggerthella-like bacterium. Results The prevalences of L. crispatus, L. jensenii, and L. gasseri were significantly higher, while those of BVAB2, Megasphaera, Leptotrichia, and Eggerthella-like bacterium were significantly lower in the normal group than in the BV group. Unlike other Lactobacillus species, the prevalence of L. iners did not differ between the three groups and women with L. iners were significantly more likely to have BVAB2, Megasphaera, Leptotrichia, and Eggerthella-like bacterium. Linear regression analysis revealed associations of BVAB2 and Megasphaera with Nugent score, and multivariate regression analyses suggested a close relationship between Eggerthella-like bacterium and BV. Conclusion The BV-related bacteria, including BVAB2, Megasphaera, Leptotrichia, and Eggerthella-like bacterium, are common in the vagina of pregnant Japanese women with BV. The presence of L. iners may be correlated with vaginal colonization by these BV-related bacteria. PMID:17986357

Breast cancer (BC) is a cancer that affects working age women in Japan. The aim of this study was to examine the impact that BC has on the work-related life of Japanese women and identify factors that correlate with job resignation. A cross-sectional Internet survey of cancer survivors in Japan was conducted from December 2011 to February 2012. The questionnaire included questions regarding demographic characteristics, impact of cancer diagnosis and treatment on job resignation and consultation behavior of respondents regarding work-related issues. This study reports results obtained from 105 respondents with BC. The mean age of respondents at diagnosis was 42.5 ± 6.4 years, and the median time since diagnosis was 40 months. Thirty-one respondents (29.5%) lost their jobs, and 12 could not find another job after BC diagnosis. Nearly half of the respondents (47.6%) reported a decrease in personal income after diagnosis. Multiple logistic regression analysis revealed that contract or part time workers were significantly more likely to lose their jobs compared with regular, full time workers (odds ratio, 2.52; 95% confidence interval, 1.39 to 4.55; p<0.001). Seventy-nine respondents (75.2%) consulted someone regarding work-related issues. The most frequently consulted person was the boss at the workplace. Our findings suggest that women with BC experience various job-related problems. In order to create a supportive work environment for BC survivors, focus should be placed on facilitating communication and coordination between BC survivors, healthcare providers and coworkers.

Targeting smokers with empathy appeal antismoking public service announcements: a field experiment.

2015-01-01

A field experiment study (N = 189) was conducted to investigate the effectiveness of empathy appeal antismoking messages and their potential advantage over fear appeal messages. Data from 12 antismoking public service announcements showed that (a) smokers resist antismoking messages and (b) overall empathy appeal was equally effective as fear appeal messages. There was also evidence for moderators. First, empathy messages were more effective to women than to men. Second, fear appeal messages were more effective to occasional smokers than were empathy messages. Third, empathy messages were more effective to regular smokers than were fear appeal messages. Implications for audience segmentation and message targeting in public health antismoking efforts are discussed.

The social definition of women's smoking behaviour.

PubMed

Elkind, A K

1985-01-01

The history of women's smoking behaviour is one of changing normative definitions. Recent trends have been explained in terms of the symbolic value of smoking, representing for women freedom and independence. This view is emphasised by advertising. However, other evidence suggests the continued existence of an older, more negative cultural stereotype. A two-part study of young women undergoing professional training for nursing and teaching throws some light on the way in which female smoking behaviour is currently socially interpreted. The first phase indicated that among the minority of parents who had expressed their attitudes towards their daughter's smoking in relation to sex-role norms, smoking was presented as unacceptable for women. More than half the sample perceived a negative cultural stereotype to be operating in contemporary society and two-thirds recognised its existence in the past. This stereotype presents smoking as a male behaviour and hence inappropriate for women. Women who do smoke are liable to be labelled as having unfeminine or degrading attributes. The stereotype operated more strongly in the general social background rather than in reference to personal relationships and hence its influence on contemporary behaviour is likely to be limited. It was rejected as out-dated or a male belief by some but nevertheless it represented the personal opinion of others. In terms of a more favourable definition the female smoker was perceived in terms of an elegant/sophisticated dimension and in relation to an extrovert personality. The view of sample members that the growing acceptability of women's smoking was related to social change indirectly supported the view that sees smoking as symbolic of independence. Those who saw smoking in neutral terms, i.e. as not having sex-role attributes, perceived smoking in this sense as normal social behaviour for men and women alike. The second phase suggested that smokers and non-smokers have divergent views about

Adolescent smoking cessation efforts to date have tended to focus on regular smokers. Consequently, infrequent and occasional smokers' receptivity and response to smoking cessation interventions is unknown. To address this gap, this study examines data from the Hutchinson Study of High School Smoking-a randomized trial that examined the effectiveness of a telephone-delivered smoking cessation intervention for a large, population-based cohort of adolescent smokers proactively recruited in an educational setting. The study population included 1837 proactively identified high school smokers. Intervention receptivity, engagement, and outcomes were examined among adolescent infrequent (1-4days/month) and occasional (5-19days/month) smokers and compared with regular smokers (20 or more days/month). With regard to treatment receptivity, intervention recruitment did not differ by smoking frequency. For engagement, intervention completion rates were higher for infrequent smokers (80.5%) compared with occasional (63.8%) and regular smokers (61.5%, p<0.01). Intervention effect sizes were not statistically different across groups. Adolescent infrequent and occasional smokers are at least as receptive to a proactively delivered smoking cessation intervention as regular smokers and can benefit just as much from it. Including these adolescent smokers in cessation programs and research-with the goal of interrupting progression of smoking before young adulthood-should help reduce the high smoking prevalence among young adults.

We compare life course characteristics of a cohort of African American women (N=457) by their smoking status at age 42: never smoker (34.1%), former smoker (27.8%), or current smoker (38.1%). The Woodlawn population from which our sample is drawn has been followed from first grade (1966-67) to mid adulthood (2002-3) and is a cohort of children from a disadvantaged Chicago community. Examination of the effects of cumulative disadvantage on smoking behavior showed that nearly half of women who first lived in poverty as children, dropped out of school, became teen mothers, and were poor as young adults currently smoked; less than 22% of women with none of these difficulties were current smokers. Regression analyses focusing on smoking and evidence of social disadvantage in childhood, adolescence, and young adulthood showed that women with more education were much less likely to be current smokers. Women reporting low parental supervision in adolescence and less frequent church attendance in young adulthood and those whose mothers' reported regular smoking were significantly more likely to be current smokers. Poverty and marital status in young adulthood varied significantly among smoking categories in bivariate relationships, but not in final multivariate regression models. Few other studies have examined smoking careers with data from age 6-42, comparing social disadvantage characteristics over the life course. While marital status, church involvement and parental supervision are not usually included as measures of socioeconomic status, they represent advantages in terms of social capital and should be considered mechanisms for transmitting disparities.

It is unclear whether osteoporosis itself is a main risk factor for delayed wound healing after tooth extraction in humans. In this study, we evaluated the association between experience of delayed wound healing after last tooth extraction and self-reported kyphosis, with the possibility of having vertebral fractures, in Japanese patients. Among the 1,504 patients who responded to the structured questionnaire survey, 518 patients (134 men and 384 women) aged 55–97 years finally participated in this study. Patients who self-reported mild-moderate kyphosis were more likely to have problematic delayed wound healing after last tooth extraction than those who reported severe kyphosis (odds ratio [OR] 4.98; 95% confidence interval [CI], 1.86–13.38 and OR 2.30; 95% CI, 0.52–10.22, respectively) (p for trend = 0.005). Japanese patients with vertebral fractures may have a higher risk of having problematic delayed wound healing after tooth extraction. PMID:27848958

In this study of Japanese men and women, we determine reference values for sarcopenia and test the hypothesis that sarcopenia is associated with risk factors for cardiovascular disease, independent of waist circumference. A total of 1,488 Japanese men and women aged 18-85 years participated in this study. Appendicular muscle mass (AMM) was measured by dual-energy X-ray absorptiometry. Reference values for classes 1 and 2 sarcopenia (skeletal muscle index: AMM/height2, kg m-2) in each sex were defined as values one and two standard deviations below the sex-specific means of reference values obtained in this study from young adults aged 18-40 years. The reference values for class 1 and class 2 sarcopenia were 7.77 and 6.87 kg m-2 in men and 6.12 and 5.46 kg m-2 in women. In subjects both with class 1 and class 2 sarcopenia, body mass index and % body fat were significantly lower than in normal subjects. Despite whole-blood glycohaemoglobin A1c in men with class 1 sarcopenia was significantly higher than in normal subjects, and brachial-ankle pulse wave velocity in women both with class 1 and class 2 sarcopenia were significantly higher than in normal subjects, using one-way ANCOVA with adjustment for the covariate of waist circumference. Although sarcopenia is associated with thin body mass, it is associated with more glycation of serum proteins in men and with greater arterial stiffness in women, independent of waist circumference.

Cigarette smoking is often associated with the development of several respiratory diseases however, if diagnosed early, the changes in the lung tissue caused by smoking may be reversible. Computerised respiratory sounds have shown to be sensitive to detect changes within the lung tissue before any other measure, however it is unknown if it is able to detect changes in the lungs of healthy smokers. This study investigated the differences between computerised respiratory sounds of healthy smokers and non-smokers. Healthy smokers and non-smokers were recruited from a university campus. Respiratory sounds were recorded simultaneously at 6 chest locations (right and left anterior, lateral and posterior) using air-coupled electret microphones. Airflow (1.0-1.5 l/s) was recorded with a pneumotachograph. Breathing phases were detected using airflow signals and respiratory sounds with validated algorithms. Forty-four participants were enrolled: 18 smokers (mean age 26.2, SD = 7 years; mean FEV 1 % predicted 104.7, SD = 9) and 26 non-smokers (mean age 25.9, SD = 3.7 years; mean FEV 1 % predicted 96.8, SD = 20.2). Smokers presented significantly higher frequency at maximum sound intensity during inspiration [(M = 117, SD = 16.2 Hz vs. M = 106.4, SD = 21.6 Hz; t(43) = -2.62, p = 0.0081, d z  = 0.55)], lower expiratory sound intensities (maximum intensity: [(M = 48.2, SD = 3.8 dB vs. M = 50.9, SD = 3.2 dB; t(43) = 2.68, p = 0.001, d z  = -0.78)]; mean intensity: [(M = 31.2, SD = 3.6 dB vs. M = 33.7,SD = 3 dB; t(43) = 2.42, p = 0.001, d z  = 0.75)] and higher number of inspiratory crackles (median [interquartile range] 2.2 [1.7-3.7] vs. 1.5 [1.2-2.2], p = 0.081, U = 110, r = -0.41) than non-smokers. Significant differences between computerised respiratory sounds of smokers and non-smokers have been found. Changes in respiratory sounds are often the earliest sign of disease.

Craving and Withdrawal Symptoms During Smoking Cessation: Comparison of Pregnant and Non-Pregnant Smokers.

2016-04-01

Although pregnant smokers are aware of the negative peri- and postnatal health consequences of smoking, the cessation rate in pregnancy is low, raising the question of why pregnant smokers have difficulty quitting. Reasons might be that pregnant smokers experience more intense craving and withdrawal symptoms than non-pregnant smokers. We compared craving and withdrawal in 306 pregnant smokers versus 93 non-pregnant women using data from two smoking cessation trials. Complete data were analyzed using pre-quit and post-quit (2 weeks after quit date) craving and withdrawal measured by the 12-item French Tobacco Craving Questionnaire (FTCQ-12) and French Minnesota Nicotine Withdrawal Scale (FMNWS). Pregnant smokers started smoking and smoked regularly earlier and succeeded far less at quitting smoking by week 2 than the general population of smokers (11% versus 43%). Post-quit date FTCQ-12 general score was higher in pregnant smokers compared to comparison groups, and was driven by elevated emotionality and expectancy. FMNWS decreased significantly less among pregnant smokers than among non-pregnant smokers. Insufficient reduction of craving and withdrawal symptoms in response to a quit attempt may partially explain why pregnant smokers may have more difficulty quitting than non-pregnant smokers. Because this was a historical comparison, findings are preliminary; however, they might foster further investigation of differences in craving and withdrawal symptoms in pregnant versus non-pregnant smokers.

Although tobacco smoking is a major risk factor for chronic obstructive pulmonary disease (COPD), more than one-fourth of COPD patients are non-smokers. In this cross-sectional study, the differences in COPD phenotypes between non-smokers and smokers in male subjects were investigated and were focused on structural lung changes using a quantitative assessment of computed tomography (CT) images. They divided male participants with COPD, from a Korean cohort near a cement plant, into non-smokers and smokers by a cutoff of a 5 pack-year smoking history. Clinical characteristics, including age, body mass index (BMI), spirometry results, history of biomass smoke exposure, and CT measurements, were compared between the two groups. Emphysema index (EI) and mean wall area percentage (MWA %) were used to evaluate the structural lung changes on volumetric CT scans. The non-smoker group (n = 49) had younger patients and had a greater BMI than the smoker group (n = 113) (P < .05). Spirometry results, including post-bronchodilator forced expiratory volume in 1 s, were comparable between the two groups. More smokers had emphysema than non-smokers (EI 10.0 vs. 6.5, P < .001), but after accounting the potential confounders in model analysis, the difference was borderline significance (P = .051). In the subgroup of biomass smoke-exposed subjects, MWA% was significantly greater in smokers than in non-smokers (MWA 69.1 vs. 65.3, P = .03), while EI was not statistically different (EI 7.1 vs. 10.4, P = .52). Non-smoker males with COPD were younger and had a greater BMI than the smokers. Tobacco smoke exposure seemed to be associated with an emphysema-predominant phenotype, while biomass smoke exposure exhibited a significant interaction with tobacco smoking in an airway-predominant phenotype. © 2016 John Wiley & Sons Ltd.

This study examines attitudinal differences related to osteoporosis between first and second generation Japanese-American women. In an interview, the women completed a battery of tests assessing their attitudes, values, and beliefs about the diagnosis, treatment, and follow-up care of osteoporosis. The groups differed in their general knowledge of osteoporosis, perceptions of the disease, attributions of its causes, anticipated and preferred support mechanisms for care, and anticipated areas of concern for self-or other-care. There were also considerable differences in treatment compliance and feelings toward physicians. The findings were discussed in relation to the effects of culture on health-care attitudes and behaviors.

Background: 1,3-Butadiene (BD) is an important carcinogen in tobacco smoke that undergoes metabolic activation to DNA-reactive epoxides. These species can be detoxified via glutathione conjugation and excreted in urine as the corresponding N-acetylcysteine conjugates. We hypothesize that single nucleotide polymorphisms (SNPs) in BD-metabolizing genes may change the balance of BD bioactivation and detoxification in White, Japanese American, and African American smokers, potentially contributing to ethnic differences in lung cancer risk. Methods: We measured the levels of BD metabolites, 1- and 2-( N -acetyl-L-cysteine-S-yl)-1-hydroxybut-3-ene (MHBMA) and N -acetyl- S -(3,4-dihydroxybutyl)-L-cysteine (DHBMA), in urine samples from a total of 1,072 White, Japanese American, and African American smokers and adjusted these values for body mass index, age, batch, and total nicotine equivalents. We also conducted a genome-wide association study to identify genetic determinants of BD metabolism. Results: We found that mean urinary MHBMA concentrations differed significantly by ethnicity ( P = 4.0 × 10 -25 ). African Americans excreted the highest levels of MHBMA followed by Whites and Japanese Americans. MHBMA levels were affected by GSTT1 gene copy number ( P < 0.0001); conditional on GSTT1 , no other polymorphisms showed a significant association. Urinary DHBMA levels also differed between ethnic groups ( P = 3.3 × 10 -4 ), but were not affected by GSTT1 copy number ( P = 0.226). Conclusions: GSTT1 gene deletion has a strong effect on urinary MHBMA levels, and therefore BD metabolism, in smokers. Impact: Our results show that the order of MHBMA levels among ethnic groups is consistent with their respective lung cancer risk and can be partially explained by GSTT1 genotype.

The Japanese Domestic Labor Debate.

ERIC Educational Resources Information Center

Ueno, Chizuko

The changing role of Japanese women can be seen in the stages of a domestic labor debate which occurred at three different times in the past 30 years. The first debate began with Ayako Ishigaki's (1955) insistence that women should have a job outside the home. Wartime production helped break down traditional divisions of labor by encouraging women…

We studied characteristics of past smokers according to the duration of cessation of smoking based on data from a population-based survey. Lifestyle, prevalences of various symptoms and diseases and other factors were compared among current smokers (8507 males and 2012 females), past smokers (4423 males and 684 females) and non-smokers (2431 males and 12,859 females) aged 40 years and over. Compared to current smokers, past smokers consumed more bread, milk, vegetables, fruit and black tea, and less rice, pickles, instant noodles, coffee and alcohol, had lower prevalences of cough, sputum and anorexia, participated more in cancer screening tests, weighed more, included more professional and administrative workers and had more non-smoking spouses. These characteristics resembled those of non-smokers. But past smokers had high prevalences of several cardiovascular and respiratory diseases compared to current smokers. Daily intake of coffee was inversely associated and daily intakes of fruit and milk were positively associated with the duration of abstinence from smoking after adjusting for other factors in both sexes. These results suggest that lifestyle of past smokers may contribute to risk reduction for several diseases.

Cigarette companies increasingly promote novel smokeless tobacco products to smokers, encouraging them to use smokeless tobacco in smoke-free environments. New messages may counteract this promotion. We developed 12 initial anti-smokeless message ideas and tested them in eight online focus groups with 75 US smokers. Those smokers who never tried smokeless tobacco were unaware of health risks of novel smokeless tobacco products, perceived scary messages as effective and acknowledged the addictive nature of nicotine. Smokers who had tried smokeless tobacco shared their personal (mainly negative) experiences with smokeless tobacco, were aware of health risks of novel smokeless tobacco products, but denied personal addiction, and misinterpreted or disregarded more threatening messages. Portraying women as smokeless tobacco users was perceived as unbelievable, and emphasizing the lack of appeal of novel smokeless tobacco products was perceived as encouraging continued smoking. Future ads should educate smokers about risks of novel smokeless tobacco products, but past users and never users may require different message strategies.

To identify similarities and differences in beliefs about the causes of Bulimia Nervosa (BN) held by Asian (Japanese) women and Western (Australian) women, and hence, to examine the applicability of belief models of eating disorders (ED) across different cultures. Four hundred three Japanese and 256 Australian female university students (aged 17-35 years) completed a questionnaire that gauged beliefs about the causes of BN. Among the Australian women, the four-component structure of perceived causes (dieting and eating practices, family dynamics, socio-cultural pressure, and psychological vulnerability) found in Dryer et al. (2012) was replicated. Among the Japanese women, however, a three-component structure (without the psychological vulnerability component) was obtained. The groups also differed in the causal component they most strongly endorsed, that being socio-cultural pressure for the Australian women, and dieting and eating practices for the Japanese women. The Japanese participants were found to endorse three out of the four Western-based causal explanations for BN, but the relative importance they placed on those explanations differed from that of the Australian participants. Further research is needed, particularly to establish whether Japanese women simply fail to see psychological vulnerability as a viable cause of BN, or there are in fact cultural differences in the extent to which such vulnerability causes BN. © 2014 Wiley Periodicals, Inc.

To assess the impact of plain packaging on visual attention towards health warning information on cigarette packs. Mixed-model experimental design, comprising smoking status as a between-subjects factor, and package type (branded versus plain) as a within-subjects factor. University laboratory. Convenience sample of young adults, comprising non-smokers (n = 15), weekly smokers (n = 14) and daily smokers (n = 14). Number of saccades (eye movements) towards health warnings on cigarette packs, to directly index visual attention. Analysis of variance indicated more eye movements (i.e. greater visual attention) towards health warnings compared to brand information on plain packs versus branded packs. This effect was observed among non-smokers and weekly smokers, but not daily smokers. Among non-smokers and non-daily cigarette smokers, plain packaging appears to increase visual attention towards health warning information and away from brand information. © 2011 The Authors, Addiction © 2011 Society for the Study of Addiction.

The proportion of never-smokers with non-small cell lung cancer (NSCLC) is increasing, but that in Korea has not been well addressed in a large population. We aimed to evaluate the proportion and clinical features of never-smokers with NSCLC in a large single institution. We analyzed clinical data of 1860 consecutive patients who were newly diagnosed with NSCLC between June 2011 and December 2014. Of the 1860 NSCLC patients, 707 (38.0%) were never-smokers. The proportions of women (83.7% vs. 5.6%) and adenocarcinoma (89.8% vs. 44.9%) were higher among never-smokers than among ever-smokers. Significantly more never-smokers were diagnosed at a younger median age (65 vs. 68 years, P < 0.001) and earlier stage (stage I-II, 44.5% vs. 38.9%, P = 0.015) compared with ever-smokers. Epidermal growth factor receptor mutations (57.8% vs. 24.4%, P < 0.001) and anaplastic lymphoma kinase rearrangements (7.8% vs. 2.8%, P < 0.001) were more common in never-smokers, whereas Kirsten rat sarcoma viral oncogene homolog mutations (5.8% vs. 9.6%, P = 0.021) were less frequently encountered in never-smokers than in ever-smokers. Never-smokers showed longer survival after adjusting for the favorable effects of younger age, female sex, adenocarcinoma histology, better performance status, early stage disease, being asymptomatic at diagnosis, received antitumor treatment, and the presence of driver mutations (hazard ratio, 0.624; 95% confidence interval, 0.460-0.848; P = 0.003). More than one-third of the Korean patients with NSCLC were never-smokers. NSCLC in never-smokers had different clinical characteristics and major driver mutations and resulted in longer overall survival compared with NSCLC in ever-smokers.

We examined the association between thymic stromal lymphopoietin (TSLP) single nucleotide polymorphisms (SNPs) and eczema in young adult Japanese women. Cases were 188 women who met the criteria of the International Study of Asthma and Allergies in Childhood (ISAAC) for eczema. Controls were 565 women without eczema according to the ISAAC criteria, who had not been diagnosed with asthma, atopic eczema, and/or allergic rhinitis by a doctor and who had no asthma as defined by the European Community Respiratory Health Survey criteria and no rhinoconjunctivitis according to the ISAAC criteria. Compared with women with the TT genotype of SNP rs1837253, those with the TC or CC genotype had a significantly increased risk of eczema after adjustment for age and smoking, although this association was not significant in crude analysis. There were no relationships between SNP rs3806933 or rs2289276 and eczema. The TC and CC genotypes combined of SNP rs1837253 may be significantly positively associated with eczema.

According to theories of addictive behaviors, approach and attentional biases toward smoking-related cues play a crucial role in tobacco dependence. Several studies have investigated these biases by using various paradigms in different sample types. However, this heterogeneity makes it difficult to compare and evaluate the results. The present study aimed to address this problem, via (i) a structural comparison of different measures of approach-avoidance and a measure of smoking-related attentional biases, and (ii) using within one study different representative samples in the context of tobacco dependence. Three measures of approach-avoidance were employed: an Approach Avoidance Task (AAT), a Stimulus Response Compatibility Task (SRC), and a Single Target Implicit Association Test (ST-IAT). To assess attentional biases, a modified Stroop task including smoking-related words was administered. The study included four groups: n = 58 smokers, n = 57 non-smokers, n = 52 cravers, and n = 54 ex-smokers. We expected to find strong tobacco-related approach biases and attentional biases in smokers and cravers. However, the general pattern of results did not confirm these expectations. Approach responses assessed during the AAT and SRC did not differ between groups. Moreover, the Stroop did not show the expected interference effect. For the ST-IAT, cravers had stronger approach associations toward smoking-related cues, whereas non-smokers showed stronger avoidance associations. However, no such differences in approach-avoidance associations were found in smokers and ex-smokers. To conclude, these data do not provide evidence for a strong role of implicit approach and attentional biases toward smoking-related cues in tobacco dependency. PMID:26955359

A standardized cardiovascular risk factor examination was given to executives in the headquarters of the American Telephone and Telegraph Company and the Nippon Telegraph and Telephone Public Corporation. As expected from the national mortality data, evidence of ischaemic heart disease was more common among American than Japanese executives. The frequency of some but not all risk factors was consistent with the observed differences in ischaemic heart disease. Americans were fatter than their Japanese counterparts, obtained a higher proportion of their caloric intake from animal fats, had higher serum cholesterol levels, and more of them felt that their lives were highly stressful. On the other hand, Japanese executives were much more likely to be cigarette smokers and showed a greater increase in blood pressure with age. Serum high-density lipoprotein cholesterol levels and the ratio of saturated to unsaturated fatty acids in the serum were similar in the two groups.

Overweight and obese tobacco users possess increased risk of cancer, diabetes, heart disease and chronic tobacco-related disease. Efforts to prevent tobacco-related health risk in this comorbid population would be informed by better understanding and monitoring of trends in the concurrent use of electronic nicotine delivery systems (ENDS) among smokers in the US marketplace. The California Longitudinal Smokers Study (CLSS) established a cohort of current cigarette smokers in 2011 who were surveyed for tobacco use and health behavior at baseline and again in 2012 at follow-up. We observed a large increase in reported experimentation with ENDS. As hypothesized, overweight or obese smokers were more likely to report experimentation with ENDS, an increase that was also observed among women. Experimentation with ENDS was not associated with a reduction in use of cigarettes or a decrease in cigarette dependence in this high risk population of smokers. Continued surveillance of this vulnerable population is needed to better understand how experimentation with new ENDS products may impact health, facilitate switching to non-combustible tobacco or facilitate persistent cigarette dependence.

Smoking is the cause of inducing changes in taste functionality under conditions of chronic exposure. The objective of this study was to evaluate taste sensitivity in young smokers and non-smokers and identify any differences in the shape, density and vascularisation of the fungiform papillae (fPap) of their tongue. Sixty-two male subjects who served in the Greek military forces were randomly chosen for this study. Thirty-four were non-smokers and 28 smokers. Smokers were chosen on the basis of their habit to hold the cigarette at the centre of their lips. Taste thresholds were measured with Electrogustometry (EGM). The morphology and density of the fungiform papillae (fPap) at the tip of the tongue were examined with Contact Endoscopy (CE). There was found statistically important difference (p < 0.05) between the taste thresholds of the two groups although not all smokers presented with elevated taste thresholds: Six of them (21%) had taste thresholds similar to those of non-smokers. Differences concerning the shape and the vessels of the fungiform papillae between the groups were also detected. Fewer and flatter fPap were found in 22 smokers (79%). The majority of smokers shown elevated taste thresholds in comparison to non-smokers. Smoking is an important factor which can lead to decreased taste sensitivity. The combination of methods, such as EGM and CE, can provide useful information about the vascularisation of taste buds and their functional ability.

Facial proportions are of interest in orthodontics. The null hypothesis is that there is no difference in golden proportions of the soft-tissue facial balance between Japanese and white women. Facial proportions were assessed by examining photographs of 3 groups of Asian women: group 1, 30 young adult patients with a skeletal Class 1 occlusion; group 2, 30 models; and group 3, 14 popular actresses. Photographic prints or slides were digitized for image analysis. Group 1 subjects had standardized photos taken as part of their treatment. Photos of the subjects in groups 2 and 3 were collected from magazines and other sources and were of varying sizes; therefore, the output image size was not considered. The range of measurement errors was 0.17% to 1.16%. ANOVA was selected because the data set was normally distributed with homogeneous variances. The subjects in the 3 groups showed good total facial proportions. The proportions of the face-height components in group 1 were similar to the golden proportion, which indicated a longer, lower facial height and shorter nose. Group 2 differed from the golden proportion, with a short, lower facial height. Group 3 had golden proportions in all 7 measurements. The proportion of the face width deviated from the golden proportion, indicating a small mouth or wide-set eyes in groups 1 and 2. The null hypothesis was verified in the group 3 actresses in the facial height components. Some measurements in groups 1 and 2 showed different facial proportions that deviated from the golden proportion (ratio).

To examine the influence of smoking history on the diagnosis and other tumor characteristics of upper tract urothelial carcinoma in Japan. A total of 1509 patients with upper tract urothelial carcinoma who were diagnosed in 2005 from 348 Japanese institutions were registered using the multi-institutional national database of the Japanese Urological Association and included in this analysis. Clinical data of the patients were collected in 2011. The associations between the patients' self-reported smoking history and their age at the diagnosis of upper tract urothelial carcinoma, sex, pathological T stage and tumor grade were analyzed. The mean age at the diagnosis of upper tract urothelial carcinoma was approximately 5 years earlier for the 238 current smokers than for the 618 current non-smokers (P < 0.0001). Similar associations between smoking and the early diagnosis of upper tract urothelial carcinoma were shown in the sex subgroups and in subgroups stratified by pathological T stages. Among the current smokers, the age at diagnosis for the smoking ≥ 20 cigarettes per day group was 6.5 years lower than that of the < 20 cigarettes per day group, which was significantly different (P < 0.0001). Current smoking is a significant risk factor for the earlier diagnosis of upper tract urothelial carcinoma. The finding is important from the perspective of both healthcare and medical economies. © 2015 The Japanese Urological Association.

To compare umbilical and uterine artery Doppler waveforms and fetal size at 20 weeks between smokers and nonsmokers. Prospective cohort study. Auckland, New Zealand and Adelaide, Australia. Nulliparous participants in the Screening for Pregnancy Endpoints (SCOPE) study. Self-reported smoking status was determined at 15 +/- 1 weeks' gestation. At the 20 +/- 1 week anatomy scan, uterine and umbilical Doppler resistance indices (RI) and fetal measurements were compared between smokers and nonsmokers. Umbilical and mean uterine artery Doppler RI values, abnormal umbilical and uterine Doppler (RI > 90th centile) and fetal biometry. Among the 2459 women, 248 (10%) were smokers. Smokers had higher umbilical RI [0.75 (SD 0.06) versus 0.73 (0.06), P < 0.0001] and mean uterine RI [0.59 (0.09) versus 0.56 (0.10), P < 0.0001]. They were twice as likely to have an abnormal umbilical Doppler at 20 weeks compared with nonsmokers [n = 35 (14.6%) versus n = 156 (7.2%), OR 2.21, 95% CI 1.49-3.27]. This effect remained significant after adjusting for age, ethnicity, marital status, employment and BMI (adjusted OR 1.62, 95% CI 1.03-2.54). Smokers were more likely to have an abnormal mean uterine RI [n = 33 (13.7%) versus n = 198 (9.2%), OR 1.57, 95% CI 1.06-2.33], but this association was not significant after adjusting for confounders. Fetuses of women who smoked had a small reduction in femur length and estimated weight compared with nonsmokers. At 20 weeks' gestation, women who smoke have higher umbilical artery RI, a surrogate measure for an abnormal placental villous vascular tree. This may contribute to later fetal growth restriction among smokers. Further research is needed to explore the clinical significance of these findings.

Smoking is a major risk factor for destructive periodontal disease. There is limited information with regard to effects of smoking in subjects with minimal periodontal destruction. The aim of the present investigation was to assess the development of gingival recession in young adult smokers and non-smokers. 61 systemically healthy young adults, 19 to 30 years of age completed the final examination. 30 volunteers smoked at least 20 cigarettes per day, whereas 31 subjects were non-smokers. Clinical periodontal conditions were assessed 4x within a time period of 6 months. Site-specific analyses considering the correlated structure of data were performed. At the outset, 50% of subjects presented with gingival recession at 1 or more sites. There was no significant difference in the prevalence of gingival recession between non-smokers and smokers. Severe recession in excess of 2 mm affected about 23% non-smokers but only 7% smokers. Some further gingival recession developed during the 6-month observation period. In a multivariate logistic regression analysis, the risk for recession development appeared not to be influenced by smoking status after adjusting for periodontal probing depth, recession at baseline, tooth brushing frequency, gender, jaw, tooth type and site. Present data did not support the hypothesis that smokers are at an increased risk for the development of gingival recession.

There is a dearth of studies regarding the influence of cigarette smoking on periodontal inflammatory conditions among patients with type 2 diabetes mellitus (T2DM). The aim of the present study is to assess periodontal inflammatory conditions among smokers and never-smokers with and without T2DM. One hundred individuals (50 patients with T2DM [25 smokers and 25 never-smokers] and 50 controls [25 smokers and 25 never-smokers]) were included. Information regarding age, sex, duration and daily frequency of smoking, duration and treatment of diabetes, and oral hygiene was recorded using a questionnaire. Periodontal parameters (plaque index [PI], bleeding on probing [BOP], probing depth [PD], clinical attachment loss [AL], and marginal bone loss [MBL]) were measured. Hemoglobin A1c (HbA1c) levels were also recorded. Mean age, monthly income status, and education levels were comparable among smokers and never-smokers with and without T2DM. Mean HbA1c levels were significantly higher among patients with T2DM (8.2% ± 0.1%) compared with controls (4.4% ± 0.3%) (P <0.05). Smokers in the control group were smoking significantly greater numbers of cigarettes (15.5 ± 2.5 cigarettes daily) compared with smokers with T2DM (6.2 ± 2.1 cigarettes daily) (P <0.05). Periodontal parameters were comparable among smokers and never-smokers with T2DM. Among controls, periodontal parameters (PI [P <0.05], AL [P <0.05], PD ≥4 mm [P <0.05], and MBL [P <0.05]) were significantly higher in smokers than never-smokers. Never-smokers with T2DM had worse periodontal status than smokers and never-smokers in the control group (P <0.05). Periodontal inflammatory conditions are comparable among smokers and never-smokers with T2DM. Among controls, periodontal inflammation is worse among smokers than never-smokers.

Research indicates that nicotine and alcohol are often used on the same occasion. However, the reasons for their concurrent use are not well understood. We hypothesized that one reason smokers use tobacco when they drink alcohol is to compensate for alcohol's negative effects on processing capacity with nicotine's enhancement of processing capacity. As such, the present study tested this theory by using an independent groups design to examine the separate and combined acute effects of alcohol and nicotine on working memory (WM) capacity. Nonabstinent daily smokers (n = 127) performed the counting span task (CSPAN) after consuming either an alcohol (men: 0.8 g/kg; women: 0.7 g/kg) or placebo beverage and smoking either nicotinized (1.14 mg nicotine, 15.9 mg tar) or denicotinized (.06 mg nicotine, 17.9 mg tar) cigarettes. Analyses revealed that smokers who smoked the nicotinized cigarettes performed significantly worse on the CSPAN task than smokers who smoked the denicotinized cigarettes. Although there was no main effect of alcohol on WM performance, women exhibited better WM performance than men after consuming alcohol whereas men performed better than women on the WM task after consuming the placebo beverage. Findings also revealed no interaction between the two substances on WM performance. Taken together, results suggest that nicotine impairs nonabstinent smokers' verbal WM capacity and that gender moderates the effects of alcohol on WM. Furthermore, the present findings failed to support the notion that nicotine compensates for alcohol-related decrements in working memory capacity. 2010 APA, all rights reserved

To evaluate the effects of glucose metabolism related factors, such as insulin and insulin-like growth-factors (IGFs), on breast cancer development among Japanese women, we conducted a case-referent study comparing 187 women presenting with operable breast cancer and 190 women of the same age having no breast cancer. Odds ratios (OR) and 95% confidence intervals (95%CI) were determined by multiple logistic regression analysis. In the present study, no association in risk was observed with increasing levels of IGF-I or IGF binding protein-3 (IGFBP-3), before or after adjustment these factors. However, a suggestion of a positive association of an increased breast cancer risk was evident in postmenopausal women with elevated plasma insulin levels, particularly those with BMI>23.07. The OR for plasma insulin in the top tertile was 4.48 (95%CI:1.07-18.7) compared to the bottom tertile. For C-peptide, there was a similar positive association, with a corresponding OR of 2.28. In addition, we observed strong links between plasma insulin, C-peptide levels and estrogen receptor (ER) negative breast cancer, with ORs of 2.79(95%CI:1.09-7.16), and 2.52 (95%CI:0.91-6.97) respectively, for the top versus bottom tertiles. In conclusion, the present study suggested that plasma insulin level is a predictor of postmenopausal breast cancer in obese women and ER negative breast cancer. Additional studies are needed to clarify the role of glucose metabolism pathways in breast cancer development and interaction of IGF systems.

In the UK, free smoking cessation support is available to pregnant women; only a minority accesses this. 'Opt-out' referrals to stop smoking services (SSS) are recommended by UK guidelines. These involve identifying pregnant smokers using exhaled carbon monoxide (CO) and referring them for support unless they object. To assess the impact of 'opt-out' referrals for pregnant smokers on SSS uptake and effectiveness, we conducted a 'before-after' service development evaluation. In the 6-month 'before' period, there was a routine 'opt-in' referral system for self-reported smokers at antenatal 'booking' appointments. In the 6-month 'after' period, additional 'opt-out' referrals were introduced at the 12-week ultrasound appointments; women with CO≥4 ppm were referred to, and outcome data were collected from, local SSS. Approximately 2300 women attended antenatal care in each period. Before the implementation, 536 (23.4%) women reported smoking at 'booking' and 290 (12.7%) were referred to SSS. After the implementation, 524 (22.9%) women reported smoking at 'booking', an additional 156 smokers (6.8%) were identified via the 'opt-out' referrals and, in total, 421 (18.4%) were referred to SSS. Over twice as many women set a quit date with the SSS after 'opt-out' referrals were implemented (121 (5.3%, 95% CI 4.4% to 6.3%) compared to 57 (2.5%, 95% CI 1.9% to 3.2%) before implementation) and reported being abstinent 4 weeks later (93 (4.1%, 95% CI 3.3% to 4.9%) compared to 46 (2.0%, 1.5% to 2.7%) before implementation). In a hospital with an 'opt-in' referral system, adding CO screening with 'opt-out' referrals as women attended ultrasound examinations doubled the numbers of pregnant smokers setting quit dates and reporting smoking cessation.

Tobacco advertisements targeted on women: creating an awareness among women.

PubMed

Kaleta, Dorota; Usidame, Bukola; Polańska, Kinga

2011-06-01

It has been always believed that men smoke more than women, but the trend of smoking in women is increasing nowadays. In some countries there are even more female smokers than male smokers. This is a major health risk because women are present and future mothers, and increasing number of smoking women will enlarge the number of exposed children. Relatively few women are aware of gender-specific health risks, including cervical cancer, osteoporosis, poor pregnancy outcome and early menopause. Tobacco related diseases are on the rise in women, considering the fact that more women now die of lung cancer than breast cancer. Tobacco companies have invented various ways to target women through tobacco advertising despite the various bans. This inevitably leads to the increase in female smoking rates. There are various recommendations from the World Health Organization which include the need for governments to pay particular attention to protect women from the tobacco companies' attempts to lure them into lifetimes of nicotine dependence and to take up counter advertisements against the tobacco companies.

The current study utilized the intersectionality framework to explore whether smoking outcome expectancies (i.e., cognitions about the anticipated effects of smoking) were predicted by gender and ethnicity, and the gender-by-ethnicity interaction. In a cross-sectional design, daily smokers from the general community [32.2% women; Non-Hispanic African American (N=175), Non-Hispanic White (N=109), or Hispanic (N=26)] completed self-report measures on smoking expectancies and other co-factors. Results showed that women reported greater negative reinforcement (i.e., anticipated smoking-induced negative affect reduction) and weight control (i.e., anticipated smoking-induced appetite/weight suppression) expectancies than men. Hispanic (vs. African American or White) smokers endorsed greater negative reinforcement expectancies. A gender by ethnicity interaction was found for weight control expectancies, such that White women reported greater weight control expectancies than White men, but no gender differences among African American and Hispanic smokers were found. Ethnicity, gender, and their intersectionality should be considered in smoking cessation programs to target smoking-related cognitions. PMID:26438665

Post-cessation weight gain contributes to smoking relapse, especially for women. Furthermore, excess weight in the form of android or visceral fat is associated with metabolic health problems. For this study, a secondary analysis was conducted in 2015 to determine whether quitting status, achieved through a 14 week supervised exercise-aided nicotine replacement therapy (NRT) cessation program [Getting Physical on Cigarette Trial-2009 to 2013; Prapavessis, et al., 2016], affects anthropometric and body composition parameters in female smokers (N = 413, M age = 42.39 years). Anthropometric (weight and BMI) and body composition (% total body fat, % android fat, lean mass and visceral fat) indices were assessed at baseline and end of treatment. Smoking status was confirmed weekly from expired breath carbon monoxide. Adherence to exercise and NRT patch was calculated from the number of exercise sessions attended and patches worn to the number of exercise sessions offered and patches supplied, respectively. Factorial (smoking status) ANCOVAs controlling for baseline anthropometric and body composition parameters as well as adherence to exercise and NRT revealed significant differences in weight (p = .033; ɳ p 2  = 0.017) and BMI (p = .020; ɳ p 2  = 0.020) at week 14. This equated to abstainers weighing 1.26 kg more and having a 0.52 higher BMI than smokers. No significant differences were found for any of the body composition parameters at week 14 (ɳ p 2 range from 0.001-0.007). Abstainers gain modest weight compared to smokers. This weight gain is related to increases in lean mass and not total, android, or visceral fat. Copyright © 2018 Elsevier Ltd. All rights reserved.

Childcare issue and family care issue are critical factors for women doctors to make a career as a neurologist in Japan. To know the actual business conditions of Japanese neurologists an online questioner survey was conducted. Answers were obtained from 737 members of Japanese Society of Neurology and 21 neurological medical facilities. Most of the answers were form members at three major metropolitan areas such as Tokyo, Osaka and Nagoya. Nobody from some prefectures was replied any answer. Almost sixty percent woman doctors had to change their working style from full time to part time at their child raising period and had difficulty with returning to full time job. Some neurologists have answered they used paid vacation to care their families and they felt they could not keep it for a longer period. At 70 percent of medical facilities sick child day care center were not operated. Opinions form members extremely varied from "In the first place woman doctors are unnecessary"to "With the help of the partner I have survived my child raising period".

We evaluated the impact of a lifestyle intervention on the cardiometabolic risk profile of women participating in the Study on Diabetes and Associated Diseases in the Japanese-Brazilian Population in Bauru. This was a non-controlled experimental study including clinical and laboratory values at baseline and after a 1-year intervention period. 401 Japanese-Brazilian women were examined (age 60.8+/-11.7 years), and 365 classified for metabolic syndrome (prevalence = 50.6%). Subjects with metabolic syndrome were older than those without (63.0+/-10.0 vs. 56.7+/-11.6 years, p < 0.01). After intervention, improvements in variables were found, except for C-reactive protein. Body mass index and waist circumference decreased, but adiposity reduction was more pronounced in the abdominal region (87.0+/-9.7 to 84.5+/-11.2cm, p < 0.001). Intervention-induced differences in total cholesterol, LDL, and post-challenge glucose were significant; women who lost more than 5% body weight showed a better profile than those who did not. The lifestyle intervention in Japanese-Brazilian women at high cardiometabolic risk improved anthropometric and laboratory parameters, but it is not known whether such benefits will persist and result in long-term reduction in cardiovascular events.

To compare the health, health risk behaviors and stress levels of college female smokers and non-smokers. Forty-one college women, ages 18-21 years, participated in an interview and completed a health survey and the Derogatis Stress Profile. The smokers perceived themselves to be more overweight (Chi square, p = < .001). Smokers used more marijuana (Chi square, p = < .003) and had higher scores on depression [t (39) = 2.29, p = .028], hostility [t (39) = 2.562, p = .014] and perceived quality of health [t (39) = 2.72, p = .01]. In the interview, smokers identified social situations involving alcohol as the time they would most likely smoke. Smokers did not smoke when ill and all were interested in quitting. The non-smoking women support smoking cessation for their peers. College alcohol and substance use prevention and treatment programs should address tobacco cessation. The majority of college women are not smokers and could be resources to encourage smoking cessation among their peers. Smoking cessation at this age has dramatic implications for future health.

Breast cancer is the most common invasive cancer among women and its incidence is increasing. Risk assessment is valuable and recent methods are incorporating novel biomarkers such as mammographic density. Artificial neural networks (ANN) are adaptive algorithms capable of performing pattern-to-pattern learning and are well suited for medical applications. They are potentially useful for calibrating full-field digital mammography (FFDM) for quantitative analysis. This study uses ANN modeling to estimate volumetric breast density (VBD) from FFDM on Japanese women with and without breast cancer. ANN calibration of VBD was performed using phantom data for one FFDM system. Mammograms of 46 Japanese women diagnosed with invasive carcinoma and 53 with negative findings were analyzed using ANN models learned. ANN-estimated VBD was validated against phantom data, compared intra-patient, with qualitative composition scoring, with MRI VBD, and inter-patient with classical risk factors of breast cancer as well as cancer status. Phantom validations reached an R 2 of 0.993. Intra-patient validations ranged from R 2 of 0.789 with VBD to 0.908 with breast volume. ANN VBD agreed well with BI-RADS scoring and MRI VBD with R 2 ranging from 0.665 with VBD to 0.852 with breast volume. VBD was significantly higher in women with cancer. Associations with age, BMI, menopause, and cancer status previously reported were also confirmed. ANN modeling appears to produce reasonable measures of mammographic density validated with phantoms, with existing measures of breast density, and with classical biomarkers of breast cancer. FFDM VBD is significantly higher in Japanese women with cancer.

Data were derived from the National Institute for Longevity Sciences-Longitudinal Study of Aging. Subjects comprised 403 men and 373 women aged 60-81 years at baseline who participated in the follow-up study at least once. Bean, soy product and soy isoflavone intake was assessed using a 3-day dietary record at baseline. Cognitive function was assessed by the Mini-Mental State Examination (MMSE). MMSE scores of ≤23 were used to define cognitive impairment. The relationship between bean, soy product and soy isoflavone intake and cognitive impairment was assessed using a generalized estimating equation. Multivariate-adjusted odds ratios (95% confidence intervals) for cognitive impairment with a 1 s.d. increase in total bean, total soybean and total soy isoflavone intakes were 0.48 (0.28-0.81; p = 0.006), 0.51 (0.32-0.83; p = 0.007), and 0.55 (0.32-0.93; p = 0.026), respectively, in women. Total soybean and soy isoflavone intake might decrease the risk of cognitive impairment in elderly Japanese women.

Lung cancer is the leading cause of cancer-related mortality. While the majority of lung cancers are associated with tobacco smoke, approximately 10-15% of U.S. lung cancers occur in never smokers. Evidence suggests that lung cancer in never smokers appears to be a distinct disease caused by driver mutations which are different than the genetic pathways observed with lung cancer in smokers. A meta-analysis of human epidemiologic data was conducted to evaluate the profile of common or therapy-targetable mutations in lung cancers of never and ever smokers. Epidemiologic studies (N=167) representing over 63,000 lung cancer cases were identified and used to calculate summary odds ratios for lung cancer in never and ever smokers containing gene mutations: EGFR, chromosomal rearrangements and fusion of EML4 and ALK, and KRAS. This analysis also considered the effect of histopathology, smoking status, sex, and ethnicity. There were significantly increased odds of presenting the EGFR and ALK-EML4 mutations in 1) adenocarcinomas compared to non-small cell lung cancer and 2) never smokers compared to ever smokers. The prevalence of EGFR mutations was higher in Asian women as compared to women of Caucasian/Mixed ethnicity. As the smoking history increased, there was a decreased odds for exhibiting the EGFR mutation, particularly for cases >30 pack-years. Compared to ever smokers, never smokers had a decreased odds of KRAS mutations among those of Caucasian/Mixed ethnicity (OR=0.22, 95% CI: 0.17-0.29) and those of Asian ethnicity (OR=0.39, 95% CI: 0.30-0.50). Our findings show that key driver mutations and several patient features are highly prevalent in lung cancers of never smokers. These associations may be helpful as patient demographic models are developed to predict successful outcomes of targeted therapeutic interventions NSCLC. Copyright © 2016 Elsevier Ireland Ltd.

Drinking water arsenic (WAs) exposure has been linked to a number of detrimental health outcomes including anemia, primarily among pregnant women. Little is known about the effects of arsenic (As) on hematological disorders among men. We have examined the role of As exposure on hematological indicators of anemia in a group of men exposed to a wide range of As in their drinking water. We conducted a cross-sectional investigation among 119 healthy men in the Health Effects of As Longitudinal Study (HEALS) cohort, in rural Bangladesh. The participants are part of an ongoing study focused on evaluating the influence of As and smoking on immune function. Samples were collected at recruitment and analyzed for water As, urinary As (UAs) and UAs metabolites to assess As exposure. Blood samples were also collected at recruitment and assayed immediately for hematological parameters. We found that increased WAs levels were associated with decreased red blood cell counts [β=-0.13, p<0.0001] as well as hematocrit packed cell volumes [β=-0.68, p=0.008] following adjustment for age, smoking, body mass index and polycyclic aromatic hydrocarbon-DNA adducts. Other measures of As exposure (UAs and its metabolites) demonstrated similar associations. Slightly stronger effects were observed among smokers. We also observed an effect of As on hemoglobin among smokers in relation to UAs [β=-0.54, p<0.05]. Our analysis revealed effects of As exposure on hematological indicators of anemia in a group of healthy male smokers and non-smokers. Copyright © 2017 Elsevier Inc. All rights reserved.

The pulmonary and cardiovascular ramifications of smoking are well documented and this also applies to increased wound healing complications in smokers. The aim of this study was to ascertain whether preoperatively refraining from smoking would affect the incidence of wound healing disorders. Between 2006 and 2008 a total of 295 patients underwent aesthetic (n = 167) or reconstructive surgery (n = 128). They were divided into three groups: A (n = 98) non-smokers for at least 2 years, B (n = 99) patients who refrained from smoking 6 weeks prior to surgery and C (n = 98) smokers. Smoking abstinence was verified by cotinine tests. Wound healing complications were defined as dehiscent wounds, wound infections, atypical scar formation and adiponecrosis. Smokers developed wound healing complications in 48.2% of cases, non-smokers in 21.0% and patients who had stopped smoking for 6 weeks in 30.8% of cases (p = 0.006). Elective surgery should only be performed on non-smokers and smokers who had refrained from smoking for at least 6 weeks to reduce wound healing complications as far as possible.

Context Sex differences exist in the reinforcing effects of nicotine, smoking cessation rates, and in response to nicotine replacement therapies. Sex differences in availability of nicotinic acetylcholine receptors containing the β2 subunit (β2*-nAChRs) may underlie differential nicotine and tobacco smoking effects and related behaviors in women and men. Objective To examine β2*-nAChR availability between male and female smokers and nonsmokers. To determine relationships between β2*-nAChR availability and tobacco smoking characteristics and female sex steroid hormones. Design Male (n=26) and female (n=28) tobacco smokers participated in one [123I]5-IA-85380 ([123I]5-IA) single photon emission computed tomography (SPECT) scan at 7–9 days of abstinence. Age-matched male (n=26) and female (n=30) nonsmokers participated in a single [123I]5-IA SPECT scan. All participants completed 1 magnetic resonance imaging study. Setting Academic Imaging Center Participants Tobacco smokers (n=54) and age- and sex-matched nonsmokers (n=56). Main Outcome Measure [123I]5-IA SPECT images were converted to equilibrium distribution volumes and analyzed using regions-of-interest. Results β2*-nAChR availability was significantly higher in male smokers compared to male nonsmokers in striatum, cortex and cerebellum, but female smokers did not have higher β2*-nAChR availability than female nonsmokers in any region. In women, β2*-nAChR availability in the cortex and cerebellum was negatively and significantly correlated with progesterone level on the day of the scan. In female smokers, on the day of the scan, progesterone levels were positively and significantly correlated with depressive symptoms, craving for a cigarette, and nicotine withdrawal. Conclusions The regulatory effects of nicotine in the brain, i.e., tobacco-smoking induced upregulation of β2*-nAChRs, appear to be distinctly different between men and women, and female sex hormones likely play a role in this regulation

To explore the impact, if any, that using plain (non-branded) cigarette packs in real-life settings has on young adult smokers. Naturalistic-type research was employed, where smokers used brown 'plain' packs for 2 weeks and their regular packs for 2 weeks, in real-life settings. Participants were recruited in Glasgow, Scotland. Of the 140 smokers aged 18-35 years who participated in the naturalistic study, 48 correctly completed and returned all questionnaires. Over the 4-week study period, participants completed a questionnaire twice a week assessing pack perceptions and feelings, feelings about smoking, salience of health warnings and smoking-related behaviours. A subsample of 18 participated in a post-study interview, which employed a semistructured topic guide to assess perceptions and experiences of using plain packs. Trends in the data show that in comparison with branded packaging, plain packaging increased negative perceptions and feelings about the pack and about smoking. Plain packaging also increased avoidant behaviour (hiding the pack, covering the pack), certain smoking cessation behaviours, such as smoking less around others and forgoing cigarettes, and thinking about quitting. Almost half (n=8) of those in the post-study interview, predominantly women (n=6), reported that the use of plain packs had either increased avoidant behaviour or reduced consumption. This pilot naturalistic study suggests that plain packaging could potentially help reduce tobacco consumption among some young adult smokers, and women in particular. Employing an innovative research methodology, the findings of this study are consistent with, and indeed support, past plain packaging research.

To compare the pregnancy outcome and cord blood cotinine levels between secondhand smokers and non-secondhand smokers. This was a cross-sectional comparative study in a Malaysian tertiary obstetric hospital involving 200 non-smoking pregnant women at term, of whom 100 were secondhand smokers and 100 were non-secondhand smokers. Those with multiple pregnancies, with a body mass index (BMI) of more than 30kg/m 2 or who delivered by Caesarean section were excluded. The participants' basic demographic details, delivery details, neonatal outcome and placental weight were recorded. Umbilical cord blood samples were obtained, and cord blood cotinine levels were measured with a Cotinine ELISA kit. The primary outcomes were baby's birth weight, length, and head circumference, Apgar score at 5min and placental weight. The secondary outcome was difference in cord blood cotinine levels between the two groups and the correlation of these differences with the neonatal outcome. The secondhand smoker group had significantly lower baby weight (2.94±0.31kg vs 3.05±0.40kg), head circumference (30.87±2.35cm vs 37.13±2.36cm), length (46.58±1.95cm vs 51.53±2.05cm) and placental weight (520±73.5g vs 596±61.3g) and significantly higher cord blood cotinine levels (16.35±12.84ng/mL vs 0.56±0.22ng/mL). Cord blood cotinine levels had significant negative correlations with placental weight (r=-0.461), baby's weight (r=-0.297), baby's head circumference (r=-0.501) and baby's length (r=-0.374). Secondhand smoke increases the incidence of adverse pregnancy outcomes (newborns'anthropometric measurements and placental weight) and causes higher cord blood cotinine levels.

Prior studies have found heightened negative affect following tobacco abstinence in women compared to men. However, experimental work addressing whether these findings generalize across racial groups is scarce. The current study investigated whether race (Non-Hispanic White vs. Non-Hispanic African American) moderated gender differences in abstinence-induced negative affect and smoking behavior. Data were collected from 2010 to 2017 from two separate laboratory studies investigating experimentally manipulated tobacco abstinence. Following a baseline session, adult daily smokers (10 cigarettes per day; women: n=297, 83.8% Non-Hispanic African American; men: n=492, 86.2% Non-Hispanic African American) attended two counterbalanced lab sessions (16 hours abstinent vs. non-abstinent) and completed self-report measures of negative affect followed by a laboratory analogue smoking reinstatement task. We found a gender race interaction for several negative affect states and composite negative affect (ßs=-.12 to -.16, ps<.05). Analyses stratified by race showed that Non-Hispanic White women compared to Non-Hispanic White men exhibited greater abstinence-induced increases in anger, anxiety, and composite negative affect (ßs=-.20 to -.29, ps<.05). No significant gender differences in abstinence-induced negative affect were found for Non-Hispanic African American smokers (ßs=.00 to -.04, ps>.05). These findings suggest that negative affect during acute tobacco abstinence may be a clinically important and intervenable factor that can inform cessation interventions specifically for Non-Hispanic White women smokers. Further empirical exploration of mechanisms underlying interactions of gender and race in tobacco addiction may benefit smoking cessation efforts in Non-Hispanic African American women smokers. The current study contributes to a scant body of research examining the intersectional influence of race and gender on abstinence-induced negative affect-a central

A nationwide survey was conducted to clarify the epidemiological features of patients with chronic pancreatitis (CP) in Japan. In the first survey, both the prevalence and the incidence of CP in 2011 were estimated. In the second survey, the clinicoepidemiological features of the patients were clarified by mailed questionnaires. Patients were diagnosed by the Japanese diagnostic criteria for chronic pancreatitis 2009. The estimated annual prevalence and incidence of CP in 2011 were 52.4/100,000 and 14.0/100,000, respectively. The sex ratio (male/female) of patients was 4.6, with a mean age of 62.3 years. Alcoholic (67.5%) was the most common and idiopathic (20.0%) was the second most common cause of CP. Comorbidity with diabetes mellitus (DM) and pancreatic calcifications (PC) occurred more frequent in ever smokers independently of their drinking status. Among patients without drinking habit, the incidences of DM and PC were significantly higher in ever smokers than in never smokers. The multiple logistic regression analysis revealed smoking was an independent factor of DM and PC in CP patients: DM, Odds ratio (OR) 1.644, 95% confidence interval (CI) 1.202 to 2.247 (P = 0.002): PC, OR 2.010, 95% CI 1.458 to 2.773 (P < 0.001). On the other hand, smoking was not identified as an independent factor for the appearance of abdominal pain by this analysis. The prevalence of Japanese patients with CP has been increasing. Smoking was identified as an independent factor related to DM and PC in Japanese CP patients. Copyright © 2014 IAP and EPC. Published by Elsevier B.V. All rights reserved.

To determine the various oral Candidal species among healthy Malaysian adults. Case-control study. This study was collaborated between the Department of Medical Microbiology, Faculty of Medicine and Department of Oral Pathology, Oral Medicine and Periodontology, Faculty of Dentistry, University of Malaya, Kuala Lumpur, Malaysia, between September 2002 till January 2004. One hundred adults (50 smokers and 50 non-smokers), aged between 40 and 70 years were studied. Swabs and carbohydrate assimilation (Saboraud Dextrose Agar, Corn Meal Agar, API 20C AUX System) were performed. Specimens were collected from dorsum of the tongue, buccal mucosa and commissures (right and left each). Colony forms were established by positive colony forming units, on SDA medium (24-48 hours). Germ tube test for (true/pseudohyphae) growth was done on Corn Meal Agar Medium. Candida biotypes were evaluated by API 20C AUX system, which had a numerical 7 digit profile, added to evaluate a definite Candida species. Thirty-five percent of Malaysian adults harbored Candida intraorally. Candidal species identified among 100 subjects had C. albicans (27) 77%, C. glabrata (3) 8%, C. famata, C. tropicalis, C. krusei, C. lusitaniae and C. guilliermondii (1) 3% each. Thirty-three positive cases comprised of 35 species i.e. two cases had two species each. Fifty seven percent of these were smokers and 43% non-smokers. These included 40% Chinese, 36% Malays and 24% Indians. Species were, however, not specified according to intra-oral sites i.e. buccal, commissural mucosa and dorsum of tongue. On this series C. albicans is the most common species found in the oral cavity of Malaysian adults. It is equally frequent in smokers and non-smokers, but showed a predilection for the ethnic Chinese group.

Purpose This study investigates Korean speech sound development, including articulatory error patterns, among the Japanese-Korean children whose mothers are Japanese immigrants to Korea. Methods The subjects were 28 Japanese-Korean children with normal development born to Japanese women immigrants who lived in Jeonbuk province, Korea. They were assessed through Computerized Speech Lab 4500. The control group consisted of 15 Korean children who lived in the same area. Results The values of the voice onset time of consonants /ph/, /t/, /th/, and /k*/ among the children were prolonged. The children replaced the lenis sounds with aspirated or fortis sounds rather than replacing the fortis sounds with lenis or aspirated sounds, which are typical among Japanese immigrants. The children showed numerous articulatory errors for /c/ and /l/ sounds (similar to Koreans) rather than errors on /p/ sounds, which are more frequent among Japanese immigrants. The vowel formants of the children showed a significantly prolonged vowel /o/ as compared to that of Korean children (P<0.05). The Japanese immigrants and their children showed a similar substitution /n/ for /ɧ/ [Japanese immigrants (62.5%) vs Japanese-Korean children (14.3%)], which is rarely seen among Koreans. Conclusion The findings suggest that Korean speech sound development among Japanese-Korean children is influenced not only by the Korean language environment but also by their maternal language. Therefore, appropriate language education programs may be warranted not only or immigrant women but also for their children. PMID:21189968

Nicotine concentrations were measured in saliva and urine samples collected from 82 smokers and 56 non-smokers after a morning at work. Each subject answered a series of questions related to their recent intentional or passive exposure to tobacco smoke. All non-smokers had measurable amounts of nicotine in both saliva and urine. Those non-smokers who reported recent exposure to tobacco smoke had significantly higher nicotine concentrations (p less than 0.001) than those who had not been exposed; their concentrations overlapped those of smokers who had smoked up to three cigarettes before sampling had the greatest influence on nicotine concentrations (r=0.62 for saliva and r=0.51 for urine). Neither the nicotine for yield of cigarettes nor the self-reported degree of inhalation had any significant effect on nicotine concentrations. PMID:6802384

Participants and Methods: Participants of this study were 4,454 women aged 40-69 years, classified into the following five groups based on their occupation: unemployed, 1,432; agriculture, 439; self-employed, 1,596; white collared, 793; and blue collared, 194. Participants' perceived health was assessed using a symptoms checklist called the Todai Health Index (THI, later renamed as the Total Health Index) in a baseline survey conducted in 1993. The mortality risk of the participants was assessed using the Cox's Proportional Hazards Model. Results: The means of the percentile values on the Total Scale 1 in the THI were as follows: agriculture, 43.7; unemployed, 50.8; self-employed, 52.5; white collared, 53.0; and blue collared, 56.1, with lower percentile values indicating better perceived health. The results showed that women engaged in agriculture were in significantly better health than were those in the other four occupations. The hazard ratios (HRs) and 95% confidence intervals of the occupational groups adjusted for age, area of residence, and Total Scale 1 scores were as follows: agriculture (reference group), 1; white collared, 1.16 (0.77-1.74); self-employed, 1.25 (0.87-1.78); unemployed, 1.27 (0.91-1.77); and blue collared, 1.50 (0.86-2.60). Conclusions: Women engaged in agriculture had a significantly higher tendency to have a better health status on the THI as compared to those from the other four occupational groups, and they exhibited the lowest HR as compared to their counterparts, though not statistically significant. We concluded that the perceived health status of unemployed women was similar to that of women engaged in agriculture.

Maternal vitamin D deficiency causes pregnancy complications and delayed skeletal development in offspring. This study aimed at identifying demographic and lifestyle factors associated with vitamin D status in pregnant Japanese women. A total of 284 healthy pregnant women in the second trimester were recruited at a university hospital in Tokyo, between June 2010 and July 2011. Serum 25-hydroxyvitamin D (25(OH)D) concentrations were measured using chemiluminescent immunoassay. We assessed vitamin D intake using a self-administered diet history questionnaire and asked participants about lifestyle variables, including daily duration of sunlight exposure and supplement use. The mean (SD) serum 25(OH)D concentration was 9.8 (4.7) ng/mL. Almost 60% of the participants had severe vitamin D deficiency (measured as 25(OH)D<10 ng/mL). Multiple regression analysis showed that multigravidity, pre-pregnancy non-underweight status, higher energy-adjusted vitamin D intake, and use of vitamin D supplements were correlated with higher serum 25(OH)D concentrations (β=0.245, β=-0.119, β=0.226, and β=0.197, respectively). In the summer investigation, women with longer durations of sunlight exposure had significantly higher serum 25(OH)D concentrations (β=0.201) that were unrelated to the factors outlined previously. In the winter investigation, women with a high education level had higher serum 25(OH)D concentrations than others (β=0.330). Our results would be useful for identifying pregnant women at a high risk of low vitamin D status, such as primigravidae and those with pre-pregnancy underweight status, low education level, low vitamin D intake, and short durations of sunlight exposure.

The in vitro activities of 10 antimicrobial agents against 159 bacterial vaginosis-associated anaerobic isolates from pregnant Japanese and Thai women were determined. Clindamycin, imipenem, cefmetazole, amoxicillin, amoxicillin-clavulanate, and metronidazole were highly active against all anaerobic isolates except Prevotella bivia and Mobiluncus species, which were resistant to amoxicillin and metronidazole, respectively. Cefotiam, ceftazidime, and ofloxacin were variably effective, while cefaclor was the least effective agent.

Few studies have investigated differences in age- and gender-specific educational gradients in tobacco smoking among the whole range of adult age groups. We examined educational inequality in smoking among Japanese adults aged 25-94 years. Using a large nationally representative sample (167,925 men and 186,588 women) in 2010, prevalence of current smoking and heavy smoking among daily smokers and their inequalities attributable to educational attainment were analyzed according to sex and age groups. Among men aged 25-34 years, junior high school graduates had the highest current smoking prevalence at 68.4% (95% confidence interval [CI], 66.0%-70.6%), and graduate school graduates had the lowest at 19.4% (95% CI, 17.2%-21.9%). High school graduates had the second highest current smoking prevalence (e.g., 55.9%; 95% CI, 54.9%-56.8% in men aged 25-34 years). Among men aged 75-94 years, the difference in current smoking across educational categories was small. A similar but steeper educational gradient in current smoking was observed among women. Among women aged 25-34 years, junior high school graduates had the highest current smoking prevalence at 49.3% (95% CI, 46.3%-52.3%), and graduate school graduates had the lowest at 4.8% (95% CI, 2.9%-7.4%). Compared with older age groups, such as 65-94 years, younger age groups, such as 25-54 years, had higher estimates of inequality indicators for educational inequality in both current and heavy smoking in both sexes. Educational inequalities in current and heavy smoking were apparent and large in the young population compared with older generations. The current study provides basic data on educational inequalities in smoking among Japanese adults. Copyright © 2016 The Authors. Production and hosting by Elsevier B.V. All rights reserved.

Higher morbidity caused by smoking-related diseases could increase health costs. We analyzed differences in the use of healthcare resources, healthcare costs and days of work absenteeism among smokers and non-smokers. Cross-sectional study in smokers and non-smokers, aged between 45 and 74 years, from one urban health area. The variables studied were: age, sex, alcohol intake, physical activity, obesity, diseases, attendance at primary care clinics and hospital emergency rooms, days of hospitalization, prescription drug consumption and work absenteeism (in days). Annual cost according to the unit cost of each service (direct costs), and indirect costs according to the number of days missed from work was calculated. Crude and adjusted risks were calculated using logistic regression. Five hundred patients were included: 50% were smokers, 74% (372) men and 26% (128) women. Smokers used more healthcare resources, consumed more prescription drugs and had more days off work than non-smokers. Respective direct and indirect costs in smokers were 848.64 euros (IQ 25-75: 332.65-1517.10) and 2253.90 euros (IQ 25-75: 1024.50-13113.60), and in non-smokers were 474.71 euros (IQ 25-75: 172.88-979.59) and 1434.30 euros (IQ 25-75: 614.70-4712.70). The likelihood of generating high healthcare costs was more than double for smokers (OR=2.14; 95% CI: 1.44-3.19). More investment in programs for the prevention and treatment of smoking, as a health policy priority, could help to reduce the health and social costs of smoking. Copyright © 2015 SEPAR.

Endothelin-1 (ET-1) is a potent vasoconstrictor produced by vascular endothelial cells, and a known marker of endothelial dysfunction. However, the acute and chronic effects of smoking and nicotine gum on the ET-1 response to acute physical stress in young healthy smokers have not been investigated. Healthy smokers (n=35) and non-smokers (n=35) underwent an exercise test to exhaustion (maximal oxygen consumption) on a treadmill. Smokers were assessed a) after 12h smoking abstinence (termed chronic smoking), b) immediately after smoking one cigarette (termed acute smoking), and c) immediately after chewing nicotine gum. Blood was drawn immediately pre-exercise, and 3 minutes post-exercise. During exercise, cardiorespiratory parameters were obtained breath-by-breath using an automated metabolic cart. Plasma ET-1 levels were quantified using enzyme-linked immunosorbent-assay. The above protocol was designed to incorporate exercise as a vascular stressor to reveal changes that would not be detected at rest. Mean age was 28.6±7.2 years and body mass index (BMI) was 23.6±3.2 kg/m(2). Post-exercise ET-1 levels were significantly lower than pre-exercise levels in non-smokers (P<0.001) and smokers under all three conditions (P=0.005, P<0.001, P=0.001, respectively). There were no differences in post-exercise ET-1 levels between non-smokers and smokers under all three conditions, however the absolute and relative decrease in ET-1 levels was significantly smaller in chronic smokers compared with non-smokers (P=0.007 and P=0.004). Chronic smokers had a significantly lower exercise-induced change in tidal volume (P=0.050), fraction of expired CO2 (P=0.021), oxygen consumption (P=0.005), carbon dioxide elimination (P=0.004) and peak expiratory flow (P=0.003) compared with non-smokers. Furthermore, the decrease in ET-1 observed in non-smokers in response to exercise was significantly associated with exercise induced-changes in inspiratory time, time for a tidal volume cycle

The proportion of smokers who do not smoke daily has increased over time, but nondaily smokers are a heterogeneous group. We compare characteristics and other tobacco product use of infrequent nondaily, frequent nondaily, and daily US adult smokers. We analyzed data from the 1998, 2000, 2005, and 2010 National Health Interview Surveys. Current smokers were categorized as daily, infrequent nondaily (smoked 1-12 days in the past 30 days), and frequent nondaily (smoked 13-29 days in the past 30 days) smokers. Multinomial logistic regression analysis was used to analyze the correlates of infrequent nondaily, frequent nondaily, and daily smoking. Among current smokers, 8.3% were infrequent nondaily, 8.1% were frequent nondaily, and 83.6% were daily smokers. The prevalence of infrequent versus daily smoking increased over time, with a smaller increase among non-Hispanic Blacks than non-Hispanic Whites. The adjusted odds of both infrequent and frequent smoking versus daily smoking differed by age, race/ethnicity, education, poverty status, marital status, region, quit attempts in the past 12 months, and binge drinking. Snuff users (vs. non-snuff users) were 2.4 times as likely to be infrequent than daily smokers. There were also differences in race/ethnicity, education, marital status, region, quit attempts, and snuff use between infrequent versus frequent smokers. Infrequent smokers differ from both frequent and daily smokers in socio-demographics, quit attempts, and snuff use. The heterogeneity of nondaily smokers should be considered in developing targeted tobacco control and smoking cessation programs. Infrequent and frequent nondaily smokers were found to differ from daily smokers in age, race/ethnicity, education, poverty status, marital status, region, and quit attempts and they were different from each other in race/ethnicity, education, marital status, region, and quit attempts. Binge drinkers were more likely to be infrequent smokers and frequent smokers versus

This cohort study of 1,614 postmenopausal Japanese women followed for 6.7 years showed that overweight/obesity and underweight are both risk factors for fractures at different sites. Fracture risk assessment may be improved if fracture sites are taken into account and BMI is categorized. The effect of body mass index (BMI) on fracture at a given level of bone mineral density (BMD) is controversial, since varying associations between BMI and fracture sites have been reported. A total of 1,614 postmenopausal Japanese women were followed for 6.7 years in a hospital-based cohort study. Endpoints included incident vertebral, femoral neck, and long-bone fractures. Rate ratios were estimated by Poisson regression models adjusted for age, diabetes mellitus, BMD, prior fracture, back pain, and treatment by estrogen. Over a mean follow-up period of 6.7 years, a total of 254 clinical and 335 morphometric vertebral fractures, 48 femoral neck fractures, and 159 long-bone fractures were observed. Incidence rates of vertebral fracture in underweight and normal weight women were significantly lower than overweight or obese women by 0.45 (95 % confidence interval: 0.32 to 0.63) and 0.61 (0.50 to 0.74), respectively, if BMD and other risk factors were adjusted, and by 0.66 (0.48 to 0.90) and 0.70 (0.58 to 0.84) if only BMD was not adjusted. Incidence rates of femoral neck and long-bone fractures in the underweight group were higher than the overweight/obese group by 2.15 (0.73 to 6.34) and 1.51 (0.82 to 2.77) and were similar between normal weight and overweight/obesity. Overweight/obesity and underweight are both risk factors for fractures at different sites. Fracture risk assessment may be improved if fracture sites are taken into account and BMI is categorized.

We estimated the effective duration of cigarette smoking using the data of lung cancer mortality among male smokers of a large-scale cohort study in Japan and evaluated its role in the lung cancer risk difference between male smokers of the Japanese cohort and the British physicians' cohort. By selecting male cohort members who answered that they had started smoking at ages 18-22 (average = 20.3), the subjects of our analysis, which numbered 49,013, were made relatively homogeneous in terms of age at which smoking was started. Assuming lung cancer mortality to be proportional to the 4.5th power of the effective duration of cigarette smoking, i.e., (age-theta)4.5, as was proposed on the basis of the British cohort study by Doll and Peto, the parameter theta was estimated to be 29.4 for male smokers aged 40-64 in 1966; therefore, the estimated duration of cigarette smoking was, on average, 9.1 years (95% confidence interval = 5.8-11.6) shorter than that calculated from the reported age at which smoking was started. Our findings suggested that the low lung cancer mortality relative to daily cigarette consumption in Japan resulted from the shorter duration of cigarette smoking in the Japanese cohort, possibly due to the severe shortage of cigarettes during and shortly after World War II. Once the effective duration of cigarette smoking was adjusted, lung cancer mortality in the range of 5-34 cigarettes per day was fairly comparable to that observed among the cohort of male British physicians.

Rapid population aging in Japan has led to rising demands for informal care giving. Traditionally, care giving for aging parents has fallen disproportionately on the shoulders of women living in multigenerational households. However, rising labor force participation by Japanese women, declining marriage and fertility rates, and women's changing expectations have combined to produce unprecedented strains on traditional multigenerational households where care giving to elders traditionally takes place. In this paper, we explored gender-specific relationships between family structure, stress and worries, and health behaviors, using linked data from two national surveys conducted in Japan: the 1995 Comprehensive Survey of the Living Conditions of People on Health and Welfare, and the 1995 National Nutrition Survey. We found that women in multigenerational households reported more care-giving worries, and also less future health and financial worries. Living with parents was associated with protective health behaviors (less smoking, less heavy drinking), but also more sedentary behavior among women, while men in "sandwich" families (i.e., living with both parents and children) reported heavier smoking. The association of family structure and health behavior was not mediated by worries. Living alone was associated with worse health for women. These findings suggest gender-specific patterns of worries and health behaviors that reflect both the health-protecting and health-damaging effects of living in multigenerational households.

The current study deals with the heart rate variability (HRV) and wavelet-based ECG signal analysis of smokers and non-smokers. The results of HRV indicated dominance towards the sympathetic nervous system activity in smokers. The heart rate was found to be higher in case of smokers as compared to non-smokers ( p < 0.05). The frequency domain analysis showed an increase in the LF and LF/HF components with a subsequent decrease in the HF component. The HRV features were analyzed for classification of the smokers from the non-smokers. The results indicated that when RMSSD, SD1 and RR-mean features were used concurrently a classification efficiency of > 90 % was achieved. The wavelet decomposition of the ECG signal was done using the Daubechies (db 6) wavelet family. No difference was observed between the smokers and non-smokers which apparently suggested that smoking does not affect the conduction pathway of heart.

The relative validity of food frequency questionnaires for estimating long-chain polyunsaturated fatty acid (LC-PUFA) intake among pregnant Japanese women is currently unclear. The aim of this study was to verify the external validity of a food frequency questionnaire, originally developed for non-pregnant adults, to assess the dietary intake of LC-PUFA using dietary records and serum phospholipid levels among Japanese women in early and late pregnancy. A validation study involving 188 participants in early pregnancy and 169 participants in late pregnancy was conducted. Intake LC-PUFA was estimated using a food frequency questionnaire and evaluated using a 3-day dietary record and serum phospholipid concentrations in both early and late pregnancy. The food frequency questionnaire provided estimates of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) intake with higher precision than dietary records in both early and late pregnancy. Significant correlations were observed for LC-PUFA intake estimated using dietary records in both early and late pregnancy, particularly for EPA and DHA (correlation coefficients ranged from 0.34 to 0.40, p < 0.0001). Similarly, high correlations for EPA and DHA in serum phospholipid composition were also observed in both early and late pregnancy (correlation coefficients ranged 0.27 to 0.34, p < 0.0001). Our findings suggest that the food frequency questionnaire, which was originally designed for non-pregnant adults and was evaluated in this study against dietary records and biological markers, has good validity for assessing LC-PUFA intake, especially EPA and DHA intake, among Japanese women in early and late pregnancy.

Mesolimbic and nigrostriatal dopaminergic pathways play important roles in both the rewarding and conditioning effects of drugs. The dopamine transporter (DAT) is of central importance in regulating dopaminergic neurotransmission and in particular in activating the striatal D2-like receptors. Molecular imaging studies of the relationship between DAT availability/dopamine synthesis capacity and active cigarette smoking have shown conflicting results. Through the collaboration between 13 SPECT centres located in 10 different European countries, a database of FP-CIT-binding in healthy controls was established. We used the database to test the hypothesis that striatal DAT availability is changed in active smokers compared to non-smokers and ex-smokers. A total of 129 healthy volunteers were included. Subjects were divided into three categories according to past and present tobacco smoking: (1) non-smokers (n = 64), (2) ex-smokers (n = 39) and (3) active smokers (n = 26). For imaging of the DAT availability, we used [123I]FP-CIT (DaTSCAN) and single photon emission computed tomography (SPECT). Data were collected in collaboration between 13 SPECT centres located in 10 different European countries. The striatal measure of DAT availability was analyzed in a multiple regression model with age, SPECT centre and smoking as predictor. There was no statistically significant difference in DAT availability between the groups of active smokers, ex-smokers and non-smokers (p = 0.34). Further, we could not demonstrate a significant association between striatal DAT and the number of cigarettes per day or total lifetime cigarette packages in smokers and ex-smokers. Our results do not support the hypothesis that large differences in striatal DAT availability are present in smokers compared to ex-smokers and healthy volunteers with no history of smoking.

Lifestyle factors, including food and nutrition, physical activity, body composition and reproductive factors, and single nucleotide polymorphisms (SNPs) are associated with breast cancer risk, but few studies of these factors have been performed in the Japanese population. Thus, the goals of this study were to validate the association between reported SNPs and breast cancer risk in the Japanese population and to evaluate the effects of SNP genotypes and lifestyle factors on breast cancer risk. A case-control study in 472 patients and 464 controls was conducted from December 2010 to November 2011. Lifestyle was examined using a self-administered questionnaire. We analyzed 16 breast cancer-associated SNPs based on previous GWAS or candidate-gene association studies. Age or multivariate-adjusted odds ratios (OR) and 95% confidence intervals (95% CI) were estimated from logistic regression analyses. High BMI and current or former smoking were significantly associated with an increased breast cancer risk, while intake of meat, mushrooms, yellow and green vegetables, coffee, and green tea, current leisure-time exercise, and education were significantly associated with a decreased risk. Three SNPs were significantly associated with a breast cancer risk in multivariate analysis: rs2046210 (per allele OR=1.37 [95% CI: 1.11-1.70]), rs3757318 (OR=1.33[1.05-1.69]), and rs3803662 (OR=1.28 [1.07-1.55]). In 2046210 risk allele carriers, leisure-time exercise was associated with a significantly decreased risk for breast cancer, whereas current smoking and high BMI were associated with a significantly decreased risk in non-risk allele carriers. In Japanese women, rs2046210 and 3757318 located near the ESR1 gene are associated with a risk of breast cancer, as in other Asian women. However, our findings suggest that exercise can decrease this risk in allele carriers.

An Intersectional Analysis of Women's Experiences of Smoking-Related Stigma.

In this article, we explore how young women encounter and counter discourses of smoking-related stigma. Twenty-seven young Australian women, smokers and ex-smokers, took part in interviews. A sub-sample of 18 participants took photographs to document their smoking experience, and took part in a second interview. Data were analyzed through Foucauldian discourse analysis. Four discourses were identified: "smoking as stigmatized," "the smoking double standard," "smoking as lower class," and "smokers as bad mothers." The women negotiated stigma in a variety of ways, shifting between agreeing, disagreeing, challenging, and displacing stigma onto "other" smokers. These experiences and negotiations of smoking-related stigma were shaped by intersecting identities, including gender, cultural background, social class, and mothering, which at times, compounded levels of stigmatization. It is concluded that tobacco control measures should consider the negative implications of smoking-related stigma, and the potential for women to experience compounding levels of stigma.

Although bone mineral density (BMD) is a complex trait that is influenced by both genetic and environmental factors, heritability studies in twins and families have shown that genetic factors account for 60-85% of its variance. We examined the relation of the variable number of tandem repeats (VNTR) polymorphism of the monoamine oxidase A gene (MAOA) and the A↷G (Thr484Ala) polymorphism of the SH2B adaptor protein 1 gene (SH2B1) to BMD in community-dwelling Japanese women and men. The 2235 subjects (1107 women, 1128 men) were aged 40-79 years and were randomly recruited for a population-based prospective cohort study of aging and age-related diseases in Japan. BMD at the distal and proximal radius was measured by peripheral quantitative computed tomography, and the BMD of the total body, lumbar spine (L2-L4), right femoral neck and right trochanter was measured by dual-energy X-ray absorptiometry. The genotypes of the VNTR polymorphism of MAOA were determined by DNA fragment analysis, and those of the A↷G (Thr484Ala) polymorphism of SH2B1 by melting curve analysis. The VNTR polymorphism of MAOA was associated with the BMD of the distal radius, total body, lumbar spine and trochanter in all women, and with the BMD of the total body and trochanter in postmenopausal ones, with the L (four repeats) and S (two or three repeats) alleles reflecting increased and decreased BMD, respectively. The A↷G (Thr484Ala) polymorphism of SH2B1 was associated with the BMD of the lumbar spine in all women, with the BMD of the proximal radius in premenopausal women and with the BMD of the lumbar spine, femoral neck and trochanter in postmenopausal women, with the variant G allele being related to increased BMD. These results suggest that MAOA and SH2B1 are determinative loci for bone mass in Japanese women, especially in postmenopausal ones.

Visual attention to health warnings on plain tobacco packaging in adolescent smokers and non-smokers.

Previous research with adults indicates that plain packaging increases visual attention to health warnings in adult non-smokers and weekly smokers, but not daily smokers. The present research extends this study to adolescents aged 14-19 years. Mixed-model experimental design, with smoking status as a between-subjects factor and pack type (branded or plain pack) and eye gaze location (health warning or branding) as within-subjects factors. Three secondary schools in Bristol, UK. A convenience sample of adolescents comprising never-smokers (n = 26), experimenters (n = 34), weekly smokers (n = 13) and daily smokers (n = 14). Number of eye movements to health warnings and branding on plain and branded packs. Analysis of variance, irrespective of smoking status revealed more eye movements to health warnings than branding on plain packs, but an equal number of eye movements to both regions on branded packs (P = 0.033). This was observed among experimenters (P < 0.001) and weekly smokers (P = 0.047), but not among never-smokers or daily smokers. Among experimenters and weekly smokers, plain packaging increases visual attention to health warnings and away from branding. Daily smokers, even relatively early in their smoking careers, seem to avoid the health warnings on cigarette packs. Adolescent never-smokers attend the health warnings preferentially on both types of packs, a finding which may reflect their decision not to smoke. © 2012 The Authors, Addiction © 2012 Society for the Study of Addiction.

Previous studies have suggested that body mass index (BMI) is related to personality traits, and that there may be gender specificity in this relationship. In the present study, the association between BMI and the 7 dimensions of the Temperament and Character Inventory was investigated in 567 Japanese healthy volunteers, with special attention on gender effects. Height and weight were self-reported, and BMI was calculated from these values. In the multiple regression analyses, higher BMI was related to higher scores of harm avoidance (p < 0.05) and lower scores of self-directedness (p < 0.01) in women, whereas BMI was not related to any Temperament and Character Inventory dimension in men. The present study suggests that increasing BMI is associated with increased harm avoidance and decreased self-directedness in women but not in men in healthy subjects.

This study examines the presence and correlates of gender disparities in smoking cessation among lower income smokers prescribed nicotine replacement medication. We examined quit rates (7-day abstinence point prevalence) among a cohort of smokers who filled prescriptions for nicotine replacement (N = 1,782), using Minnesota Health Care Programs' (e.g., Medicaid) pharmacy claims databases (2005-2006) and mixed-mode survey protocols. A cohort of smokers who recently filled a prescription for nicotine replacement was stratified by race, and then subjects were selected by simple random sample from each race, oversampling the nonWhite groups (N = 1,782). The primary outcome was point prevalence of 7-day abstinence, and outcomes were assessed about 8 months after the nicotine replacement therapy (NRT) index prescription fill date using a mixed-mode survey protocol. Final interaction models were constructed using backward elimination. Abstinence rates were 11.4% among women and 19.2% among men (p = .02) and remained marginally significant after controlling for demographics, mental and physical health, period of cigarette abstinence, social environment, religious attendance, perceived stress, and NRT prescription type (p = .08). There was a significant Gender x Employment interaction (p = .02). Among men, quit rates were higher among the employed (26%) compared with the unemployed (16%); among women, quit rates were lower among those who were employed (8%) compared with those who were unemployed (14%). Results suggest the need for research on factors specific to women's work roles or workplaces that inhibit cessation as well as cessation programs tailored to low-income, employed female smokers. On-site workplace interventions and flexible counseling programs may be especially beneficial.

Objectives. We sought to describe the range of exposure to secondhand smoke (SHS) among women and children living with smokers around the world and generate locally relevant data to motivate the development of tobacco control policies and interventions in developing countries. Methods. In 2006, we conducted a cross-sectional exposure survey to measure air nicotine concentrations in households and hair nicotine concentrations among nonsmoking women and children in convenience samples of 40 households in 31 countries. Results. Median air nicotine concentration was 17 times higher in households with smokers (0.18 μg/m3) compared with households without smokers (0.01 μg/m3). Air nicotine and hair nicotine concentrations in women and children increased with the number of smokers in the household. The dose–response relationship was steeper among children. Air nicotine concentrations increased an estimated 12.9 times (95% confidence interval=9.4, 17.6) in households allowing smoking inside compared with those prohibiting smoking inside. Conclusions. Our results indicate that women and children living with smokers are at increased risk of premature death and disease from exposure to SHS. Interventions to protect women and children from household SHS need to be strengthened. PMID:18309121

Intimate partner violence (IPV) is a serious problem in Japan. The purpose of this study was to describe IPV as perceived by Japanese adult females who were in a heterosexual marriage and lived with their spouses at the time of IPV. Using a cross-sectional retroactive qualitative description research design with individual face-to-face in-depth interviews, a purposive sample of 11 Japanese adult females from three urban areas in Japan was interviewed. All women reported that they and their husbands were born in Japan. At the time of the interview, the women had a mean age of 38 years whereas at the time of the IPV, their mean age was 28 years. Data was analyzed using the directed qualitative content analysis method. The results revealed that IPV occurred at the women’s homes primarily at night. All the women reported that they experienced physical and emotional abuse and 82% reported experiencing sexual abuse. Additionally, 64% reported that their parents-in-law emotionally abused them. Communication between these women and their husbands were characterized as unilateral with the husbands initiating and dominating the conversations with orders, lectures, and reprimands. The women identified that the cultural influences of the Japanese patriarchal system that reinforces male superiority and dominance and women inferiority were directly related to IPV. The implication is that health professionals need to actively advocate for effective legislation and policies to address IPV in Japan. PMID:19465572

Although effective treatments exist, most women who smoke during pregnancy neither seek nor receive treatment. Complementary and alternative medicine (CAM) treatments (eg, mindfulness, yoga, and acupuncture) may be attractive, low-cost options that can be used to assist a large proportion of pregnant women with smoking cessation. This study examined participant characteristics and treatment utilization among pregnant smokers in the National Survey on Drug Use and Health (NSDUH) and the National Health Interview Survey (NHIS) in order to explore the prevalence and predictors of CAM use for any purpose within this population. Results indicated that a considerable proportion (6.9%-29.1%) of pregnant smokers are already accessing CAM, particularly Whites and those of greater socioeconomic status. Use of yoga, meditation, and massage increased across study waves. NSDUH participants were most likely to report seeking chiropractic or massage therapy; NHIS participants most frequently reported use of herbs/supplements, deep breathing, and meditation. Up to roughly a quarter of women endorsed traditional/conventional and CAM treatment use, suggesting that some pregnant smokers are open to trying a variety of approaches to promote health. Further research is needed to validate CAM treatments for smoking cessation and to guide safety and treatment recommendations during pregnancy. CAM treatments may be an attractive treatment alternative for pregnant smokers. However, no previous investigations have examined whether pregnant smokers seek out these treatments. Using nationally representative survey data, the present study aimed to explore whether pregnant smokers use CAM treatments. We found that approximately 7%-29% of pregnant smokers reported using a variety of CAM methods, suggesting the need for further investigation into the efficacy and dissemination of CAM for smoking in pregnancy.

The numbers of women smoking have risen 72.5% since 1990 with the increasing population - from 56,100 to 96,800 in 2012, reflecting an alarming situation in Hong Kong. The study aimed to describe the smoking behaviour, attitudes and associated factors among women in Hong Kong. A qualitative cross-sectional study involving semi-structured interview was conducted with Chinese women from five community centres in different districts in Hong Kong in 2010. A purposive sample of 73 female participants (24 current smokers, 20 ex-smokers and 29 never-smokers) were recruited. The 73 women were classified by their smoking status and age to form 15 focus groups. Most informants knew about the general health hazards of smoking, such as cancer and heart or respiratory diseases, but not about the female-specific health consequences of smoking. A few smokers considered smoking to be a weight control strategy, fearing a gain in weight if they gave up. Moreover, a few relied on smoking as a coping strategy to relieve negative emotions and stress. Additionally, a few smokers had misconceptions about giving up: that a loss of concentration would result, that continued smoking would not further affect their health as they had become desensitised to the chemicals in tobacco smoke or that quitting would harm their health. This study generates new knowledge about the behavior, attitudes, and experiences related to smoking of current female smokers, ex-smokers and non-smokers in Hong Kong, which is unique as a Chinese but highly westernized community but with a very low female smoking prevalence.

Introduction: Few studies have evaluated exercise interventions for smokers with depression or other psychiatric comorbidities. This pilot study evaluated the potential role of supervised vigorous exercise as a smoking cessation intervention for depressed females. Methods: Thirty adult women with moderate–severe depressive symptoms were enrolled and randomly assigned to 12 weeks of thrice weekly, in person sessions of vigorous intensity supervised exercise at a YMCA setting (EX; n = 15) or health education (HE; n = 15). All participants received behavioral smoking cessation counseling and nicotine patch therapy. Assessments were done in person at baseline, at the end of 12 weeks of treatment, and at 6 months post-target quit date. Primary end points were exercise adherence (proportion of 36 sessions attended) and biochemically confirmed 7-day point prevalence abstinence at Week 12. Biomarkers of inflammation were explored for differences between treatment groups and between women who smoked and those abstinent at Week 12. Results: Treatment adherence was high for both groups (72% for EX and 66% for HE; p = .55). The Week 12 smoking abstinence rate was higher for EX than HE (11/15 [73%] vs. 5/15 [33%]; p = .028), but no significant differences emerged at 6-month follow-up. Interleukin-6 levels increased more for those smoking than women abstinent at Week 12 (p = .040). Conclusions: Vigorous intensity supervised exercise is feasible and enhances short-term smoking cessation among depressed female smokers. Innovative and cost-effective strategies to bolster long-term exercise adherence and smoking cessation need evaluation in this population. Inflammatory biomarkers could be examined in future research as mediators of treatment efficacy. Implications: This preliminary study found that vigorous intensity supervised exercise is feasible and enhances short-term smoking cessation among depressed female smokers. This research addressed an important gap in the field

Maternal docosahexaenoic acid (DHA) intakes is important for brain development in fetuses. Accurate assessment of EPA and DHA intakes is required in clinical settings to identify women with deficiency of these nutrients and provide an appropriate intervention for them. We examined the validity and reproducibility of a brief-type self-administered diet history questionnaire (BDHQ) for evaluating EPA and DHA intakes of pregnant Japanese women, to establish an easily administered dietary assessment tool. A total of 105 women in the second trimester and 102 women in the third trimester were studied at a university hospital in Tokyo, between November 2010 and February 2012. The reference values for the validation study were plasma concentrations of EPA and DHA. For the reproducibility study, 54 women completed the BDHQ twice, within a 4-week period in the second trimester. Energy-adjusted intakes of EPA, DHA, and EPA+DHA were significantly associated with the corresponding plasma concentrations (rs=0.354, rs=0.305, and rs=0.327 in the second trimester; rs=0.391, rs=0.316, and rs=0.358 in the third trimester, respectively). Intraclass correlation coefficients for the two-time BDHQ were 0.543 (EPA), 0.611 (DHA), and 0.581 (EPA+DHA). In the Bland-Altman plots, the intakes of EPA, DHA, and EPA+DHA in the two-time BDHQ showed that the values for most participants were in the accepted range of agreement. BDHQ has an acceptable validity level for assessing EPA and DHA intakes among Japanese women in the second and third trimesters.

To inform consumers, U.S. Federal Courts have ordered the tobacco industry to disseminate "corrective statements" (CSs) about their deception regarding five topics: smoker health effects, nonsmoker health effects, cigarette addictiveness, design of cigarettes to increase addiction, and relative safety of light cigarettes. To determine how smokers from diverse backgrounds respond to the final, court-mandated wording of these CSs. Data were analyzed from an online consumer panel of 1,404 adult smokers who evaluated one of five CS topics (n=280-281) by reporting novelty, relevance, anger at the industry, and motivation to quit because of the CS. Logistic and linear regression models assessed main and interactive effects of race/ethnicity, gender, education, and CS topic on these responses. Data were collected in January 2013 and analyzed in March 2013. Thirty percent to 54% of participants reported that each CS provided novel information, and novelty was associated with greater relevance, anger at the industry, and motivation to quit because of the message. African Americans and Latinos were more likely than non-Hispanic whites to report that CSs were novel, and they had stronger responses to CSs across all indicators. Compared to men, women reported that CSs were more relevant and motivated them to quit. This study suggests that smokers would value and respond to CSs, particularly smokers from groups that suffer from tobacco-related health disparities. Copyright © 2014. Published by Elsevier Inc.

Differential Effect of Active Smoking on Gene Expression in Male and Female Smokers

Smoking is the second leading cause of preventable death in the United States. Cohort epidemiological studies have demonstrated that women are more vulnerable to cigarette-smoking induced diseases than their male counterparts, however, the molecular basis of these differences has remained unknown. In this study, we explored if there were differences in the gene expression patterns between male and female smokers, and how these patterns might reflect different sex-specific responses to the stress of smoking. Using whole genome microarray gene expression profiling, we found that a substantial number of oxidant related genes were expressed in both male and female smokers, however, smoking-responsive genes did indeed differ greatly between male and female smokers. Gene set enrichment analysis (GSEA) against reference oncogenic signature gene sets identified a large number of oncogenic pathway gene-sets that were significantly altered in female smokers compared to male smokers. In addition, functional annotation with Ingenuity Pathway Analysis (IPA) identified smoking-correlated genes associated with biological functions in male and female smokers that are directly relevant to well-known smoking related pathologies. However, these relevant biological functions were strikingly overrepresented in female smokers compared to male smokers. IPA network analysis with the functional categories of immune and inflammatory response gene products suggested potential interactions between smoking response and female hormones. Our results demonstrate a striking dichotomy between male and female gene expression responses to smoking. This is the first genome-wide expression study to compare the sex-specific impacts of smoking at a molecular level and suggests a novel potential connection between sex hormone signaling and smoking-induced diseases in female smokers.

In non-smokers, passive heat stress increases shear stress and vasodilation, decreasing arterial stiffness. Smokers, who reportedly have arterial dysfunction, may have similar improvements in arterial stiffness with passive heat stress. Therefore, we examined the effects of an acute bout of whole-body passive heat stress on arterial stiffness in smokers vs. non-smokers. Thirteen smokers (8.8 ± 5.5 [median = 6] cigarettes per day for >4 years) and 13 non-smokers matched for age, mass, height, and exercise habits (27 ± 8 years; 78.8 ± 15.4 kg; 177.6 ± 6.7 cm) were passively heated to 1.5 °C core temperature ( T C) increase. At baseline and each 0.5 °C T C increase, peripheral (pPWV) and central pulse wave velocity (cPWV) were measured via Doppler ultrasound. No differences existed between smokers and non-smokers for any variables (all p > 0.05), except cPWV slightly increased from baseline (526.7 ± 81.7 cm · s-1) to 1.5 °C Δ T C (579.7 ± 69.8 cm · s-1; p < 0.005), suggesting heat stress acutely increased central arterial stiffness. pPWV did not change with heating (grand mean: baseline = 691.9 ± 92.9 cm · s-1; 1.5 °C Δ T C = 691.9 ± 79.5 cm · s-1; p > 0.05). Changes in cPWV and pPWV during heating correlated ( p < 0.05) with baseline PWV in smokers (cPWV: r = -0.59; pPWV: r = -0.62) and non-smokers (cPWV: r = -0.45; pPWV: r = -0.77). Independent of smoking status, baseline stiffness appears to mediate the magnitude of heating-induced changes in arterial stiffness.

Background The prevalence and risk factors for endometriosis may differ according to diagnosis methodologies, such as study populations and diagnostic accuracy. We examined risk profiles in imaging-diagnosed endometriosis with and without surgical confirmation in a large population of Japanese women, as well as the differences in risk profiles of endometriosis based on history of infertility. Methods Questionnaires that included items on sites of endometriosis determined by imaging techniques and surgical procedure were mailed to 1025 women who self-reported endometriosis in a baseline survey of the Japan Nurses’ Health Study (n = 15 019). Results Two hundred and ten women had surgically confirmed endometriosis (Group A), 120 had imaging-diagnosed endometriosis without a surgical procedure (Group B), and 264 had adenomyosis (Group C). A short menstrual cycle at 18–22 years of age and cigarette smoking at 30 years of age were associated with significantly increased risk of endometriosis (Group A plus Group B), while older age was associated with risk of adenomyosis (Group C). In women with a history of infertility, a short menstrual cycle was associated with a significantly increased risk of endometriosis in both Group A and Group B, but risk profiles of endometriosis were different between Group A and Group B in women without a history of infertility. Conclusions Women with surgically confirmed endometriosis and those with imaging-diagnosed endometriosis without surgery have basically common risk profiles, but these risk profiles are different from those with adenomyosis. The presence of a history of infertility should be taken into consideration for evaluation of risk profiles. PMID:25716280

To address the prevalence of lung cancer in high and low-risk people according to their smoking history, age, and CT findings of emphysema. We reviewed the baseline low-dose CT scans of 62,124 current, former and never smokers, aged 40-90 to determine the prevalence of lung cancer. We performed logistic regression analysis of the prevalence of lung cancer to determine the odds ratio (OR) for emphysema, conditionally on age, female gender, and ethnicity. The prevalence of lung cancer was 1.4% (95% CI: 1.3-1.6) for current smokers, 1.1% (95% CI: 1.0-1.2) for former smokers, and 0.4% (95% CI: 0.3-0.6) for never smokers. Emphysema was identified in 28.5% (6,684), 20.6% (5,422), and 1.6% (194) of current, former, and never smokers, respectively. The prevalence of lung cancer among current smokers was 1.1% for those without emphysema vs. 2.3% for those with emphysema (odds ratio [OR] 1.8; 95% confidence interval [CI]: 1.4-2.2) and the corresponding difference for former smokers was 0.9% vs. 1.8% (OR: 1.7; 95% CI: 1.3-2.2), and for never smokers, it was 0.4% vs. 2.6% (OR: 6.3; 95% CI: 2.4-16.9). Identification of emphysema in low-dose CT scans increases the risk of lung cancer and is important in determining follow-up of current, former, and never smokers.

The smoking behavior of Hispanics, especially Mexican Americans, has been reported to differ from that of non-Hispanic whites, in both large gender differences in prevalence as well as a lower self-reported number of cigarettes smoked per day. This study compared the responses of a convenience sample of 263 Hispanic (44% Mexican American and 38% Central American) and 150 non-Hispanic white smokers, in order to identify other ethnic; gender, and acculturation differences in smoking behaviors. Hispanic women smoked fewer cigarettes and initiated smoking at a comparatively later age than Hispanic men; they were also less likely to smoke during pregnancy than non-Hispanic white women. Hispanics smoked more cigarettes on Saturday than other days, but this was not true for non-Hispanic whites. Will power (voluntad propia) and knowing the negative effects of smoking were considered the most helpful techniques for quitting by Hispanics. Considering that light smokers are able to quit with less intensive cessation techniques, these data suggest that a properly developed health education community intervention may have an impact on smoking rates among Hispanics.

Fundamental frequency and voice perturbation measures in smokers and non-smokers: An acoustic and perceptual study

NASA Astrophysics Data System (ADS)

Freeman, Allison

This research examined the fundamental frequency and perturbation (jitter % and shimmer %) measures in young adult (20-30 year-old) and middle-aged adult (40-55 year-old) smokers and non-smokers; there were 36 smokers and 36 non-smokers. Acoustic analysis was carried out utilizing one task: production of sustained /a/. These voice samples were analyzed utilizing Multi-Dimensional Voice Program (MDVP) software, which provided values for fundamental frequency, jitter %, and shimmer %.These values were analyzed for trends regarding smoking status, age, and gender. Statistical significance was found regarding the fundamental frequency, jitter %, and shimmer % for smokers as compared to non-smokers; smokers were found to have significantly lower fundamental frequency values, and significantly higher jitter % and shimmer % values. Statistical significance was not found regarding fundamental frequency, jitter %, and shimmer % for age group comparisons. With regard to gender, statistical significance was found regarding fundamental frequency; females were found to have statistically higher fundamental frequencies as compared to males. However, the relationships between gender and jitter % and shimmer % lacked statistical significance. These results indicate that smoking negatively affects voice quality. This study also examined the ability of untrained listeners to identify smokers and non-smokers based on their voices. Results of this voice perception task suggest that listeners are not accurately able to identify smokers and non-smokers, as statistical significance was not reached. However, despite a lack of significance, trends in data suggest that listeners are able to utilize voice quality to identify smokers and non-smokers.

We evaluated anthropometric parameters and physical fitness in elderly Japanese. A total of 2,106 elderly Japanese (749 men and 1,357 women), aged 60-79 years, were enrolled in a cross-sectional investigation study. Anthropometric parameters and physical fitness, i.e., muscle strength and flexibility, were measured. Of the 2,106 subjects, 569 subjects (302 men and 267 women) were further evaluated for aerobic exercise level, using the ventilatory threshold (VT). Muscle strength in subjects in their 70s was significantly lower than that in subjects in their 60s in both sexes. Two hundred and twenty-nine men (30.6%) and 540 women (39.8%) were taking no medications. In men, anthropometric parameters were significantly lower and muscle strength, flexibility, and work rate at VT were significantly higher in subjects without medications than these values in subjects with medications. In women, body weight, body mass index (BMI), and abdominal circumference were significantly lower, and muscle strength was significantly higher in subjects without medications than these values in subjects with medications. This mean value may provide a useful database for evaluating anthropometric parameters and physical fitness in elderly Japanese subjects.

Given plans to extend its regulatory authority to e-cigarettes, the Food and Drug Administration (FDA) urgently needs to understand how e-cigarettes are perceived by the public. To examine how smoking status impacts adult perceptions and expectations of e-cigarettes. We used Mechanical Turk (MTurk), a "crowdsourcing" platform, to rapidly survey a large (n = 796; female = 381; male = 415), diverse sample of adult ever (44%) and never smokers (56%), including ever (28%) and never (72%) users of e-cigarettes. Smokers and non-smokers learned about e-cigarettes primarily through the internet and conversations with others. Ever smokers were more likely than never smokers, and female current smokers were more likely than female former smokers, to have learned about e-cigarettes from point of sale advertising (p's < 0.05) and to believe that e-cigarettes help smokers quit (ps < 0.05). Among never users of e-cigarettes, current smokers were more likely than never smokers and former smokers to report that they would try e-cigarettes in the future (ps < 0.01). Current smokers' top reason for wanting to try e-cigarettes was to quit or reduce smoking (56%), while never and former smokers listed curiosity. In contrast, female current smokers' top reason for not trying e-cigarettes was health and safety concerns (44%) while males were deterred by expense (44%). Adult smokers and non-smokers have different perceptions and expectations of e-cigarettes. Public health messages regarding e-cigarettes may need to be tailored separately for persons with and without a history of using conventional cigarettes. Tailoring messages by gender within smoker groups may also improve their impact.

Previous studies have shown social support and social network variables to be important factors in smoking cessation treatment. Tobacco use is highly prevalent among individuals in methadone maintenance treatment (MMT). However, smoking cessation treatment outcomes in this vulnerable subpopulation have been poor and social support and social network variables may contribute. The current study examined the social support and social network characteristics of 151 MMT smokers involved in a randomized clinical trial of smoking cessation treatments. Participants were 50% women and 78% Caucasian. A high proportion (57%) of MMT smokers had spouses or partners who smoke and over two-thirds of households (68.5%) included at least one smoker. Our sample was characterized by relatively small social networks, but high levels of general social support and quitting support. The number of cigarettes per day was found to be positively associated with the number of smokers in the social network (r = .239, p < .05) and quitting self-efficacy was negatively associated with partner smoking (r = -.217, p < .001). Findings are discussed in the context of developing smoking cessation interventions that address the influential role of social support and social networks of smokers in MMT.

This study investigated the psychometric properties of the Japanese version of the WHOQOL-BREF among 10,693 community-based married Japanese men and women (4376 couples) who were either expecting or raising a child. Analyses of item-response distributions, internal consistency, criterion validity, and discriminant validity indicated that the scale had acceptable reliability and performed well in preliminary tests of validity. Furthermore, dyadic confirmatory factor analysis revealed that the theoretical factor structure was valid and similar across partners, suggesting that men and women define and value quality of life in a similar way.

To assess the effect of active vitamin D3 on quality of life (QOL) and pain in raloxifene-treated Japanese women with postmenopausal osteoporosis. This is a post hoc analysis of a previous prospective postmarketing observational study conducted without a comparator group. This study was conducted in 60 Japanese hospitals from September 2007 to February 2009. We compared changes from baseline in QOL and pain in patients receiving raloxifene plus active vitamin D3 with those in patients receiving raloxifene monotherapy at 8 and 24 weeks after treatment. Japan Pharmaceutical Information Center (JapicCTI-070465). QOL and pain were assessed using Short Form-8 (SF-8), European Quality of Life Instrument 5 Dimensions (EQ-5D), Japanese Osteoporosis Quality of Life Questionnaire (JOQOL), visual analogue pain scales (VAS pain), and pain frequency scores. A total of 506 patients were included in the post hoc analysis. Both raloxifene monotherapy (RLX, n = 354) and active vitamin D3 cotreatment (COMBI, n = 152) significantly improved QOL and reduced pain from the baseline at Week 8 and Week 24. The COMBI group had significantly greater improvements in JOQOL total score and activity of daily living (total) domain at Week 24 and last observation carried forward (LOCF) than the RLX group. The COMBI group also had significantly greater improvements in SF-8 domains of general health (at Week 8, Week 24, and LOCF), role physical (at Week 24 and LOCF), and mental health (at LOCF) than the RLX group. The COMBI group also had significantly greater reduction in VAS pain at LOCF than the RLX group (mean [SD]: RLX = -0.99 [2.72], COMBI = -1.54 [2.21], P = 0.042). Active vitamin D3 supplementation to raloxifene treatment for 24 weeks may have additional benefits in improving QOL and relieving pain in Japanese women with postmenopausal osteoporosis.

Yellow tongue coating is one of the clinical signs for diabetes mellitus according to traditional East Asian medicine. Few reports have been available on the association between yellow tongue coating and the prevalence of type 2 diabetes in the general population. We examined that association among population samples of non-smoking men and women. The study subjects were Japanese non-smoking men (n = 315) and women (n = 654) aged 30-79 years who resided in Toon city and participated in the Toon Health Study from July 2011 through November 2014. Tongue coating was assessed by a nationally licensed acupuncturist and classified into three categories of white (normal), light yellow, and yellow. We performed an oral glucose tolerance test to confirm the presence of diabetes mellitus and prediabetes. The associations between yellow tongue coating and the prevalence of diabetes mellitus and prediabetes were examined using multivariable logistic regression analyses, adjusting for age, sex, body mass index, drinking status, and physical activity. The multivariable odds ratios of diabetes mellitus were 1.39 (95% confidence interval [CI], 0.72-2.67) for light yellow tongue coating and 2.23 (95% CI, 1.16-4.30) for yellow tongue coating compared with white tongue coating. The respective multivariable odds ratios of prediabetes were 1.13 (95% CI, 0.80-1.61) and 1.43 (95% CI, 0.96-2.12). Yellow tongue coating was associated with higher prevalence of diabetes mellitus and tended to be associated with that of prediabetes among Japanese non-smoking men and women.

To determine age- and sex-specific reference intervals for 10 health examination items in Japanese adults. Health examination data were accumulated from 24 different prefectural health service associations affiliated with the Japan Association of Health Service. Those who were non-smokers, drank less than 7 days/week, and had a body mass index of 18.5-24.9kg/m2 were sampled as a reference population (n = 737,538; 224,947 men and 512,591 women). After classified by age and sex, reference intervals for 10 health examination items (systolic blood pressure, diastolic blood pressure, total cholesterol, triglyceride, glucose, uric acid, AST, ALT, gamma-GT, and hemoglobin) were estimated using the parametric and nonparametric methods. In every item except for hemoglobin, men had higher reference intervals than women. Systolic blood pressure, total cholesterol, and glucose showed an upward trend in values with increasing age. Hemoglobin showed a downward trend in values with increasing age. Triglyceride, ALT, and gamma-GT reached a peak in middle age. Overall, parametric estimates showed narrower reference intervals than non-parametric estimates. Reference intervals vary with age and sex. Age- and sex-specific reference intervals may contribute to better assessment of health examination data.

Whole salivary interleukin (IL)-1β and IL-6 in smokers and never-smokers with prediabetes remains uninvestigated. The aim of this study is to assess the periodontal status and whole salivary IL-1β and IL-6 levels among smokers and never-smokers with and without prediabetes (controls). Ninety-five males (45 with prediabetes and 50 systemically healthy controls) were included. Twenty-seven controls and 29 patients with prediabetes were smokers. Periodontal parameters (plaque index, bleeding on probing, probing depth, clinical attachment loss, and marginal bone loss) were measured, and the number of missing teeth were recorded. Fasting blood glucose (FBG) and hemoglobin A1c (HbA1c) levels were recorded. Unstimulated whole saliva samples were collected, unstimulated whole salivary flow rate (UWSFR) was determined, and IL-1β and IL-6 levels were measured. P values <0.05 were considered statistically significant. FBG (P <0.05) and HbA1c (P <0.05) levels were higher among patients with prediabetes than controls. All patients with prediabetes were hyperglycemic. UWSFR was significantly higher among controls than among patients with prediabetes (P <0.05). Periodontal parameters and whole salivary IL-1β and IL-6 levels were comparable among smokers and never-smokers with prediabetes. Among controls, periodontal parameters and whole salivary IL-1β and IL-6 levels were higher among smokers than never-smokers (P <0.05). Among controls, periodontal inflammation was worse, and whole salivary IL-1β and IL-6 levels are higher in smokers than never-smokers. Among patients with prediabetes, periodontal inflammation and whole salivary IL-1β and IL-6 levels were comparable between smokers and never-smokers.

Preliminary evidence, within both adults and adolescents, suggests that the intensity with which cigarettes are smoked (i.e. smoking topography) is predictive of success during a cessation attempt. These reports have also shown topography to be superior compared to other variables, such as cigarettes per day, in the prediction of abstinence. The possibility that gender may influence this predictive relationship has not been evaluated, but may be clinically useful in tailoring gender-specific interventions. Within the context of a clinical trial for smoking cessation among women, adult daily smokers completed a laboratory session that included a 1-hour ad-libitum smoking period in which measures of topography were collected (N=135). Participants were then randomized to active medication (nicotine patch vs. varenicline) and abstinence was monitored for 4 weeks. Among all smoking topography measures and all abstinence outcomes, a moderate association was found between longer puff duration and greater puff volume and continued smoking during the active 4-week treatment phase, but only within the nicotine patch group. Based on the weak topography-abstinence relationship among female smokers found in the current study, future studies should focus on explicit gender comparisons to examine if these associations are specific to or more robust in male smokers.

Background The economic consequences of environmental tobacco smoke (ETS) have been simulated using models. We examined the individual-level association between ETS exposure and medical costs among Japanese nonsmoking women. Methods This population-based cohort study enrolled women aged 40 to 79 years living in a rural community. ETS exposure in homes at baseline was assessed with a self-administered questionnaire. We then collected health insurance claims data on direct medical expenditures from 1995 through 2007. Using generalized linear models with interaction between ETS exposure level and age stratum, average total monthly expenditure (inpatient plus outpatient care) per capita for nonsmoking women highly exposed and moderately exposed to ETS were compared with expenditures for unexposed women. We performed separate analyses for survivors and nonsurvivors. Results We analyzed data from 4870 women. After adjustment for potential confounding factors, survivors aged 70 to 79 who were highly exposed to ETS incurred higher expenditures than those who were not exposed. We found no significant difference in expenditures between moderately exposed and unexposed women. Total expenditures were not significantly associated with ETS exposure among survivors aged 40 to 69 or nonsurvivors of any age stratum. Conclusions We calculated individual-level excess medical expenditures attributable to household exposure to ETS among surviving older women. The findings provide direct evidence of the economic burden of ETS, which is helpful for policymakers who seek to achieve the economically attractive goal of eliminating ETS. PMID:23183111

Smokers' and ex-smokers' understanding of electronic cigarettes: a qualitative study.

To explore among a diverse range of smokers and recent ex-smokers, particularly those from disadvantaged groups, how nicotine-containing products, particularly electronic cigarettes (e-cigarettes), are understood and experienced. Qualitative study of 64 smokers and ex-smokers in Central Scotland. Twelve focus groups and 11 individual interviews were carried out with a range of purposively selected groups. Nicotine replacement therapies and e-cigarettes were regarded as being very different products. Nicotine replacement therapies were viewed as medical products for smokers who want to quit, while e-cigarettes emerged as an ambiguous product whose meanings are still being negotiated. Participants' attitudes and intentions about smoking and quitting were especially important in shaping their understanding of these products. Four main interpretations of e-cigarettes were identified: a more satisfying replacement for smoking, an ambiguous but potentially useful device, a less desirable cigarette and a threat to smoking cessation. The acceptability of continued nicotine addiction and the similarity of e-cigarettes to conventional cigarettes were central themes on which participants held conflicting views. There was considerable uncertainty among participants around the constituents and safety of e-cigarettes. Different groups of smokers bring diverse expectations, requirements and concerns to their evaluations and therefore to the potential use of nicotine-containing products. The ambiguity around e-cigarettes in public health debates and medical practice is reflected in the positions and concerns of smokers. There is a need for both clear, up-to-date trustworthy information about their benefits and risks, and stronger regulation. Published by the BMJ Publishing Group Limited.

Background Better information on lung cancer occurrence in lifelong nonsmokers is needed to understand gender and racial disparities and to examine how factors other than active smoking influence risk in different time periods and geographic regions. Methods and Findings We pooled information on lung cancer incidence and/or death rates among self-reported never-smokers from 13 large cohort studies, representing over 630,000 and 1.8 million persons for incidence and mortality, respectively. We also abstracted population-based data for women from 22 cancer registries and ten countries in time periods and geographic regions where few women smoked. Our main findings were: (1) Men had higher death rates from lung cancer than women in all age and racial groups studied; (2) male and female incidence rates were similar when standardized across all ages 40+ y, albeit with some variation by age; (3) African Americans and Asians living in Korea and Japan (but not in the US) had higher death rates from lung cancer than individuals of European descent; (4) no temporal trends were seen when comparing incidence and death rates among US women age 40–69 y during the 1930s to contemporary populations where few women smoke, or in temporal comparisons of never-smokers in two large American Cancer Society cohorts from 1959 to 2004; and (5) lung cancer incidence rates were higher and more variable among women in East Asia than in other geographic areas with low female smoking. Conclusions These comprehensive analyses support claims that the death rate from lung cancer among never-smokers is higher in men than in women, and in African Americans and Asians residing in Asia than in individuals of European descent, but contradict assertions that risk is increasing or that women have a higher incidence rate than men. Further research is needed on the high and variable lung cancer rates among women in Pacific Rim countries. PMID:18788891

The aim of this study was to examine the impact of sexual intimate partner violence (IPV) on mental health among Japanese women and to explore to what extent sexual IPV is an important contributor to the severity of mental health problems in comparison with physical and psychological IPV. A cross-sectional analysis was conducted of the medical records of participants during psychiatric consultation at the Institute of Women's Health, Tokyo Women's Medical University, including 62 women who experienced IPV without sexual violence and 83 women who experienced IPV with sexual violence. Mental health problems were compared, including anxiety, depression, suicidality, post-traumatic stress disorder (PTSD), and dissociative experiences. The results demonstrated a higher incidence and severity of somatic symptoms, insomnia, social dysfunction, severe depression and suicidality, PTSD, and dissociative experiences among women in the sexual IPV group than in the women who experienced IPV without sexual violence. In analyzing the relative contribution of sexual, physical, and psychological violence to the severity of mental health problems of the survivors, results indicated that sexual violence was an independent predictor of both PTSD and dissociative experiences. The present research showed that significant adverse effects on mental health were observed among women who experienced IPV with sexual violence compared with the ones without. These findings provide important implications for considering the specific approaches to meet the needs of those women experiencing sexual IPV and the need for timely and effective interventions, including healthcare, social services, and primary prevention.

Periodontitis is one of the most common oral inflammatory diseases, and results in connective tissue degradation and gradual tooth loss. It manifests with formation of periodontal pockets, in which anaerobic and Gram-negative bacteria proliferate rapidly. Consequently, alteration of the subgingival microbiota is considered the primary etiologic agent of periodontitis. Previous studies have reported that smokers are at increased risk of periodontal disease, in both prevalence and severity, indicating that smoking is a risk factor for the onset and progression of the pathology. In the present study, 16S rRNA sequencing was employed to assess the subgingival microbiota in 6 smoker patients with chronic periodontitis, 6 non-smoker patients with chronic periodontitis and 8 healthy controls. The results demonstrated significant alterations in the microbial structure of periodontitis patients. High relative abundance of Parvimonans, Desulfubulbus, Paludibacter, Haemophilus, and Sphaerochaeta genera characterized subgingival microbiota of periodontitis patients, both smokers and non-smokers. Due to the high precision and sensitivity of the 16S rRNA sequencing method, analysis for low-abundant genera (including Pedobacter, Granulicatella, Paracoccus, Atopobium, Bifidobacterium, Coprococcus, Oridobacteriu, Peptococcus, Oscillospira and Akkermansia) was feasible, and revealed novel phylotypes associated with periodontitis. Of note, a major microbial community alteration was evident in smoker patients, suggesting an association between smoking and severity of subgingival dysbiosis. The present study confirmed that chronic periodontitis is a polymicrobial disease where changes in the equilibrium of subgingival microbiota contribute to severity of pathology. PMID:28260061

Carotid body O 2 -chemosensitivity determines the hypoxic ventilatory response (HVR) as part of crucial regulatory reflex within oxygen homeostasis. Nicotine has been suggested to attenuate HVR in neonates of smoking mothers. However, whether smoking affects HVR in adulthood has remained unclear and probably blurred by acute ventilatory stimulation through cigarette smoke. We hypothesized that HVR is substantially reduced in smokers when studied after an overnight abstinence from cigarettes i.e. after nicotine elimination. We therefore determined the isocapnic HVR of 23 healthy male smokers (age 33.9 ± 2.0 years, BMI 24.2 ± 0.5 kg m -2 , mean ± SEM) with a smoking history of >8 years after 12 h of abstinence and compared it to that of 23 healthy male non-smokers matched for age and BMI. Smokers and non-smokers were comparable with regard to factors known to affect isocapnic HVR such as plasma levels of glucose and thiols as well as intracellular levels of glutathione in blood mononuclear cells. As a new finding, abstinent smokers had a significantly lower isocapnic HVR (0.024 ± 0.002 vs. 0.037 ± 0.003 l min -1 % -1 BMI -1 , P = 0.002) compared to non-smokers. However, upon re-exposure to cigarettes the smokers' HVR increased immediately to the non-smokers' level. This is the first report of a substantial HVR reduction in abstinent adult smokers which appears to be masked by daily smoking routine and may therefore have been previously overlooked. A low HVR may be suggested as a novel link between smoking and aggravated hypoxemia during sleep especially in relevant clinical conditions such as COPD.

To evaluate supragingival and subgingival plaque formation on the dentogingival area in smokers and never smokers using the experimental gingivitis model and a plaque scoring system that considers the presence of an area free of plaque between plaque and the gingival sulcus called the plaque free zone (PFZ). Male volunteers, 9 current smokers and 10 never-smokers, refrained from oral hygiene procedures in the maxillary incisors and canines (test teeth) for 25 days. Under conditions of clinically healthy gingiva (phase 1) and gingival inflammation (phase 2), the supragingival plaque formation pattern was observed for 4 days in the dentogingival area. Gingival crevicular fluid was also measured. Plaque was dyed with fucsine and its presence was recorded by a calibrated examiner based on a 3-criteria scoring system: 0 - absence of stained plaque; 1 - presence of stained plaque and supragingival PFZ; 2 - presence of stained plaque and absence of PFZ, indicating that subgingival plaque formation has taken place. In both phases, smokers presented a significantly lower relative frequency of sites with subgingival plaque compared to never-smokers (P < 0.001). Mean gingival crevicular fluid was significantly higher in the presence of gingival inflammation for both groups (P = 0.001), whereas smokers demonstrated a significantly lower frequency of gingival bleeding than did non-smokers (23.6% vs 66.1%; P < 0.001). Smokers presented significantly lower percentages of sites with subgingival plaque in all experimental periods and presented less gingival inflammation as shown by GBI and gingival crevicular fluid quantification.

Introduction Oxidative stress and systemic inflammation are higher in smokers and patients with COPD; however, markers that may help differentiate between smokers and patients with COPD have not yet been identified. We hypothesized that tumor necrosis factor-alpha receptor (TNFR) and soluble form of the receptor for advanced glycation end products (sRAGE) can be indicators of COPD in asymptomatic patients. Patients and methods We evaluated 32 smokers (smoking history >10 pack-years), 32 patients with mild/moderate COPD (smokers and ex-smokers), and 32 never smokers. Concentrations of C-reactive protein (CRP), interleukin (IL)-6, TNFR1 and TNFR2, advanced glycation end products (AGEs), and the sRAGE were measured in serum. Results There were higher CRP and AGEs concentrations in smokers and in patients with COPD (P<0.001 and P=0.01, respectively) compared to controls, without statistical difference between smokers and patients with COPD. Concentrations of sRAGE, IL-6, and TNFR1 did not differ between study groups. TNFR2 was significantly higher in patients with COPD than in smokers (P=0.004) and controls (P=0.004), and the presence of COPD (P=0.02) and CRP (P=0.001) showed a positive association with TNFR2. Positive associations for smoking (P=0.04), CRP (P=0.03), and IL-6 (P=0.03) with AGEs were also found. The interaction variable (smoking × COPD) showed a positive association with IL-6. Conclusion Our data suggest that TNFR2 may be a possible marker of COPD in asymptomatic smokers and ex-smokers. Although smokers and patients with early COPD presented other increased systemic inflammation markers (eg, CRP) and oxidative stress (measured by AGEs), they did not differentiate smokers from COPD.

To estimate the maximum willingness to pay (WTP) for an effective smoking cessation treatment among smokers in Mexico and to identify the environmental, demographic, and socioeconomic factors associated with the WTP. A cross-sectional study was conducted. The sample contained 777 smokers (willingness to quit using a WTP of >0) who had responded to the 2009 Global Adult Tobacco Survey conducted in Mexico. Statistical associations and descriptive analyses were conducted to describe smokers and their WTP by using tobacco-related environmental, socioeconomic, and demographic variables. Overall, 74.4% of the smokers were men and 51.4% were daily smokers. On average, the smokers had been consuming tobacco for more than 15 years, 58.6% had made cessation attempts in the past, and around 10.0% knew about the existence of centers to aid in smoking cessation. The average WTP for an effective cessation method was US $191. Among men, the WTP was US $152 lower than among women. In all the estimated models, the higher an individual's education and socioeconomic level, the higher his or her WTP. This study suggests that Mexican smokers interested in quitting smoking attribute a high monetary value to an effective cessation method. Male smokers demonstrated less altruistic behavior than did female smokers. Mexico requires the implementation of more policies designed to support smoking cessation and to limit tobacco addiction. Expanding the availability of cessation programs and access to pharmacological treatments may contribute to reaching universal coverage by integrating new pharmacological alternatives into the health sector's medicine formulary.

1. This study examines whether the supplementation of isoflavones (ISO) exerts beneficial effects on the bone mineral density (BMD) measured by dual energy X-ray absorptiometry (DEXA). 2. Eighty-one healthy Japanese pre- and postmenopausal women were randomly assigned to the following two groups taking either ISO (100 mg) tablets (ISO group) or placebo tablets (P group) containing vitamins C (25 mg) and E (5 mg) daily for 24 weeks in a double-blind placebo controlled parallel design. 3. Seventy women completed the intervention study (34 on ISO, 36 on P), only ISO group was proven to increase significantly BMD (P < 0.05 vs before) and to significantly decrease body fat measured by the DEXA (P < 0.0001 vs before and P < 0.05 vs P group), while BMI was maintained in ISO group despite significant BMI increase in P group. Thus, percent changes in BMI were significantly different between ISO and P groups (P < 0.05) 24 weeks after the intervention. 4. This prospective DEXA study confirmed a long-term ISO supplementation, 100 mg/day could not only prevent menopausal bone resorption but also increase BMD and decrease body fat concomitantly with BMI reduction. Enough ISO supplementation may contribute to the risk reduction of osteoporosis and obesity and, thus to overall health promotion in menopausal women.

Vitamin D status and its relationship to physical performance, falls, and fractures in 495 postmenopausal women of Japanese ancestry in Hawaii were investigated. The mean 25-hydroxyvitamin D (25-OHD) was 31.94 ng/mL. No significant association of 25-OHD was demonstrated with most outcomes, possibly due to higher 25-OHD levels in this population. In this study, we investigated vitamin D status and its relationship to physical performance, muscle strength, falls, and fractures in postmenopausal Japanese females living in Hawaii. Of 510 community-dwelling women who participated in the eighth examination of the Hawaii Osteoporosis Study, 495 were included in these analyses. Multivariate regression models were used to evaluate the relationship of 25-OHD (D(3) and total) to eight performance-based measurements, 12 activities of daily living (ADLs), and muscle strength (grip, triceps, and quadriceps). Logistic regression analyses were performed to evaluate the relationship of 25-OHD to falls, vertebral fractures, and non-vertebral fractures. The mean total 25-OHD was 31.94 +/- 9.46 ng/mL; 44% of subjects had values <30 ng/mL, while none had values <10-12 ng/mL. There was little evidence of seasonal variation. Among performance-based measures, ADLs, and strength tests, only quadriceps strength was significantly associated with total 25-OHD (p = 0.0063) and 25-OHD(3) (p = 0.0001). No significant association of 25-OHD was found with vertebral or non-vertebral fractures, or incidence of one or more falls. Lack of serum 25-OHD relationship with falls and fractures or most physical performance measures in this study may be related to the low prevalence of very low 25-OHD levels in this population.

'We will speak as the smoker': the tobacco industry's smokers' rights groups.

The tobacco industry usually keeps its commercial and political communications separate. However, the images of the smoker developed by the two types of communication may contradict one another. This study assesses industry attempts to organize 'smokers' rights groups,' (SRGs) and the image of the smoker that underlay these efforts. Searches of the Legacy Tobacco Documents Library, the British American Tobacco documents database, and Tobacco Documents Online. 1100 documents pertaining to SRGs were found, including groups from across Europe and in Australia, New Zealand, and Hong Kong. From the late 1970s through the late 1990s they were active in numerous policy arenas, particularly the defeat of smoke-free laws. Their strategies included asserting their right to smoke and positioning themselves as courteous victims of tobacco control advocates. However, most SRGs were short-lived and apparently failed to inspire smokers to join in any significant numbers. SRGs conflated the legality of smoking with a right to smoke. SRGs succeeded by focusing debates about smoke-free policies on smokers rather than on smoke. However, SRGs' inability to attract members highlights the conflict between the image of the smoker in cigarette ads and that of the smokers' rights advocate. The changing social climate for smoking both compelled the industry's creation of SRGs, and created the contradictions that led to their failure. As tobacco control becomes stronger, the industry may revive this strategy in other countries. Advocates should be prepared to counter SRGs by exposing their origins and exploiting these contradictions.

Our study compared the amount of total collagen and type I collagen in ovular membranes of pregnant smokers and non-smokers. The study group consisted of 14 pregnant smokers at 24-36 weeks of gestation; 39 pregnant non-smokers between 24-36 weeks of gestation comprised the control group. The expressions of total collagen and type I collagen were analyzed using two histological sections of the fetal membranes. The assessment of total collagen was performed using the Picro-Cirius red stain, and type I collagen expression was determined by means of immunohistochemistry The Mann-Whitney test was applied to verify possible differences between the groups. The average area covered by total collagen was lower in smokers (20630.45 microm2) as compared to non-smokers (24058.61 microm2), although the difference was not statistically significant (p = 0.454). Comparison involving collagen type I deemed similar results (20001.33 microm2 vs. 25328.29 microm2, p = 0.158). The amount of total collagen and type I collagen was lower in ovular membranes of pregnant smokers as compared to non-smokers, although the difference was not statistically significant.

Fractional exhaled nitric oxide (FE NO ) is used to assess of airway inflammation; diagnose asthma and monitor adherence to advised therapy. Reliable and accurate reference values for FE NO are needed for both non-smoking and current smoking adults in the clinical setting. The present study was performed to establish reference adult FE NO values among never-smokers, former smokers and current smokers. FE NO was measured in 5265 subjects aged 25-75 years in a general-population study, using a chemiluminescence (Niox ™) analyser according to the guidelines of the American Thoracic Society and the European Respiratory Society. Atopy was based on the presence of immunoglobulin E (IgE) antibodies to common inhalant allergens (measured using Phadiatop® test). Spirometry without bronchodilation was performed and forced vital capacity (FVC), forced expired volume in 1 s (FEV 1 ) and the ratio of FEV 1 to FVC values were obtained. After excluding subjects with asthma, chronic bronchitis, spirometric airway obstruction and current cold, 3378 subjects remained. Equations for predictions of FE NO values were modelled using nonparametric regression models. FE NO levels were similar in never-smokers and former smokers, and these two groups were therefore merged into a group termed "non-smokers". Reference equations, including the 5th and 95th percentiles, were generated for female and male non-smokers, based on age, height and atopy. Regression models for current smokers were unstable. Hence, the proposed reference values for current smokers are based on the univariate distribution of FE NO and fixed cut-off limits. Reference values for FE NO among respiratory healthy non-smokers should be outlined stratified for gender using individual reference values. For current smokers separate cut-off limits are proposed.

Salivary-soluble CD44 levels in smokers and non-smokers with chronic periodontitis: a pilot study.

Smoking is the most important environmental risk factor for periodontal disease. Elevated levels of serum-soluble CD44 (sCD44) have been detected in smokers and also have been recognized as a diagnostic marker in some smoking-induced diseases. The present study investigates the salivary sCD44 profiles of smokers and non-smokers with and without chronic periodontitis in response to scaling and root planing (SRP). The study included 44 subjects divided into two groups: 22 patients with chronic periodontitis and 22 periodontally healthy subjects. Both groups were equally subdivided into smokers (n = 11) and non-smokers (n = 11). Plaque index, gingival index, probing depth, and clinical attachment level were recorded only for chronic periodontitis patients. Salivary samples were collected from all 44 patients at baseline and after 1 month of SRP from the 22 chronic periodontitis patients. Assay for salivary sCD44 was carried out by enzyme-linked immunosorbent assay. Baseline salivary sCD44 profiles were significantly higher when smokers were compared to non-smokers in both chronic periodontitis patients and the control subjects (P <0.001) with the highest levels recorded in smokers within the chronic periodontitis group. There was a significant decline in salivary sCD44 levels after treatment in the chronic periodontitis group for both smokers and non-smokers (P <0.01); however, the difference between groups was insignificant. Salivary sCD44 might be considered a biomarker of periodontal destruction in smokers and non-smokers. The research opens the door to further research into a role for CD44 as a diagnostic marker for periodontitis.

Tobacco smoke causes lung cancer in smokers and in never-smokers exposed to second-hand tobacco smoke (SHS). Nonetheless, molecular mechanisms of lung cancer in SHS-exposed never-smokers are still elusive. We studied lung cancers from current smokers (n = 109), former smokers (n = 56) and never-smokers (n = 47) for promoter hypermethylation of five tumour suppressor genes--p16, RARB, RASSF1, MGMT and DAPK1--using methylation-specific polymerase chain reaction. Lung tumours from ever-smokers suggested an increased risk of p16 hypermethylation as compared to never-smokers (P = 0.073), with former smokers having the highest frequency of p16 hypermethylation (P = 0.044 versus current smokers and P = 0.009 versus never-smokers). In the never-smoking group, p16 hypermethylation was seen in lung tumours from SHS-exposed individuals (4/33; 12%) but in none of the non-exposed individuals (0/9). The overall occurrence of hypermethylation (measured both as methylation index and as number of genes affected) was similar in those ever exposed to tobacco smoke (smokers, SHS-exposed never-smokers) and differed from non-exposed never-smokers. In multivariate analysis, p16 hypermethylation was more prevalent in lung tumours from male than female patients (P = 0.018) and in squamous cell carcinomas than in adenocarcinomas (P = 0.025). Occurrence of TP53 mutation in the tumour was associated with hypermethylation of at least one gene (P = 0.027). In all, our data suggest that promoter hypermethylation pattern in SHS-exposed never-smokers resembles that observed in smokers. Association between TP53 mutation, a hallmark of smokers' lung cancer, and methylation of one or more of the lung cancer-related genes studied, provides further evidence for common tobacco smoke-related origin for both types of molecular alterations.

Nicotine dependence has been suggested to be related to reinforcement sensitivity, which encompasses behavioral predispositions either to avoid aversive (behavioral inhibition) or to approach appetitive (behavioral activation) stimuli. Reinforcement sensitivity may shape motives for nicotine use and offer potential targets for personalized smoking cessation therapy. However, little is known regarding how reinforcement sensitivity is related to motivational processes implicated in the maintenance of smoking. Additionally, women and men differ in reinforcement sensitivity, and such difference may cause distinct relationships between reinforcement sensitivity and motivational processes for female and male smokers. In this study, the authors characterized reinforcement sensitivity in relation to affect, smoking-related reinforcement motives, and affective responses, using self-report and psychophysiological measures, in over 200 smokers before treating them. The Behavioral Inhibition/Activation Scales (BIS/BAS; Carver & White, 1994) was used to measure reinforcement sensitivity. In female and male smokers, BIS was similarly associated with negative affect and negative reinforcement of smoking. However, positive affect was positively associated with BAS Drive scores in male smokers, and this association was reversed in female smokers. BIS was positively associated with corrugator electromyographic reactivity toward negative stimuli and left frontal electroencephalogram alpha asymmetry. Female and male smokers showed similar relationships for these physiological measures. These findings suggest that reinforcement sensitivity underpins important motivational processes (e.g., affect), and gender is a moderating factor for these relationships. Future personalized smoking intervention, particularly among more dependent treatment-seeking smokers, may experiment to target individual differences in reinforcement sensitivity.

Background To inform consumers, U.S. Federal Courts have ordered the tobacco industry to disseminate “corrective statements” (CSs) about their deception regarding five topics: smoker health effects, nonsmoker health effects, cigarette addictiveness, design of cigarettes to increase addiction, and relative safety of light cigarettes. Purpose To determine how smokers from diverse backgrounds respond to the final, court-mandated wording of these CSs. Methods Data were analyzed from an online consumer panel of 1,404 adult smokers who evaluated one of five CS topics (n=280–281) by reporting novelty, relevance, anger at the industry, and motivation to quit because of the CS. Logistic and linear regression models assessed main and interactive effects of race/ethnicity, gender, education, and CS topic on these responses. Data were collected in January 2013 and analyzed in March 2013. Results Thirty percent to 54% of participants reported that each CS provided novel information, and novelty was associated with greater relevance, anger at the industry, and motivation to quit because of the message. African Americans and Latinos were more likely than non-Hispanic whites to report that CSs were novel, and they had stronger responses to CSs across all indicators. Compared to men, women reported that CSs were more relevant and motivated them to quit. Conclusions This study suggests that smokers would value and respond to CSs, particularly smokers from groups that suffer from tobacco–related health disparities. PMID:24746372

To analyze psychological morbidity as a moderator of the relationship between smoking representations and quality of life in smokers and former smokers, as well as to determine which psychological variables discriminate between smokers with and without the intention to quit smoking. This was a quantitative, correlational cross-sectional study involving a convenience sample of 224 smokers and 169 former smokers. In smokers and former smokers, psychological morbidity had a moderating effect on the relationship between mental/physical quality of life and smoking representations (cognitive representations, emotional representations, and comprehensibility). Smokers with the intention to quit smoking more often presented with low comprehensibility, threatening emotional representations, behavioral beliefs, and perceived behavioral control, as well as with normative/control beliefs, than did those without the intention to quit. The results of this study underscore the importance of the moderating effect exerted by psychological morbidity, as well as that of sociocognitive variables, among smokers who have the intention to quit smoking.

Previously, sex differences among the various tooth types in Japanese skulls were examined to facilitate choosing an implant diameter similar to the cervical diameter of each tooth, and it was found that mesiodistal diameters at the cementoenamel junction were narrower in women than in men. Also interesting and relevant to the selection of implant diameter is the possible existence of racial differences in diameters at the cementoenamel junction. The purpose of this research was to test the hypothesis that the diameter at the cementoenamel junction of the tooth differs in humans of different races. We compared 106 skulls of unknown sex collected from South Asia with the skulls of Japanese women. Our conclusions are as follows: (1) Except for the lower canine, no significant racial differences were found in the labiolingual diameter of any teeth. (2) Except for the upper canine, upper central incisor, lower second premolar, and lower first premolar, a significant racial difference was found in the mesiodistal diameter. In all teeth in which this value differed, the mesiodistal diameters of South Asians were narrower than those of Japanese women, except for the lower canine. (3) The labiolingual and mesiodistal diameters of the lower canine were significantly larger in South Asians than in Japanese women. (4) Among South Asians, no significant left/right differences were found in the diameter at the cementoenamel junction of any tooth.

Love, sex, and money are the most direct cues involved in the fundamental forms of mate preferences. These fundamental forms are not mutually exclusive but are interrelated. As a result, humans base their mate choices on multiple cues. In this study, 62 undergraduate women (M age = 20.4 yr., SD = 1.4) from China and Japan served as the participants. They performed a variation of the semantic priming task, in which they were instructed to decide by means of a key-press whether the target was human or non-human. The primes were images that portrayed potent evolutionary factors for mate preference (i.e., love, sex, and money), and the manipulation was based on whether the prime and target matched regarding gender, independent of the target decision task (human vs non-human). Participants gave faster responses to male targets than to female targets under priming. The results generally supported the evolutionary premises that assume mate preference is determined by fundamental forms of providing emotional (love), material (money), and fertility support (sex). The money priming effect was stronger in the Chinese women than in the Japanese women, suggesting that social context may influence mate preferences.

Elevation of homocysteine is associated with an increased risk for bone fractures. We previously reported that the methylenetetrahydrofolate reductase (MTHFR) gene polymorphism is associated with homocysteine levels and fracture. The association between the fracture and folate levels or their related gene polymorphisms is not completely clear. We speculated that the SLC25A32 gene, the mitochondrial inner membrane folate transporter, also could be implicated in the regulation of folate metabolism and fracture. A total of 851 Japanese postmenopausal women participated in the association study between the single nucleotide polymorphism genotype and plasma homocysteine or folate. We also tested the association between the candidate single nucleotide polymorphism and 663 postmenopausal women. The AA genotype of rs2241777 single nucleotide polymorphism at the 3'UTR region in the SLC25A32 gene was associated with lower plasma folate concentration compared with the other genotypes in 851 postmenopausal women. A total of 674 postmenopausal ambulatory Japanese women were followed up for 5.5 ± 0.1 years (mean ± SE). The AA genotype groups also showed an apparently higher rate and earlier onset of incident fractures than the other genotypes. A total of 407 participants had >70% young-adult mean bone mineral density at the start of the observation. These results show that the SLC25A32 gene polymorphism could be a risk factor for lower folate concentration and future fracture. © 2013 Japan Geriatrics Society.

Diverging effects of nicotine on motor learning performance: Improvement in deprived smokers and attenuation in non-smokers.

Nicotine modulates cognition and neuroplasticity in smokers and non-smokers. A possible mechanism for its effect on learning and memory performance is its impact on long-term potentiation (LTP) and long-term depression (LTD). As neuroplasticity is closely connected to learning processes, we aimed to explore the effect of nicotine in healthy, young smokers and non-smokers on performance of the serial reaction time task (SRTT), a sequential motor learning paradigm. 20 nicotine-deprived smokers and 20 non-smokers participated in the study and were exposed to nicotine or placebo medication. Deprived smokers under placebo medication displayed reduced performance in terms of reaction time and error rates compared to the non-smoking group. After application of nicotine, performance in smokers improved while it deteriorated in non-smokers. These results indicate a restituting effect of nicotine in smokers in terms of cognitive parameters. This sheds further light on the proposed mechanism of nicotine on learning processes, which might be linked to the addictive component of nicotine, the probability of relapse and thus needs also be addressed in cessation treatment.

Purposes of this study were 1) to examine the exercise intensity where lymphocyte apoptosis index (AI) is significantly increased in smokers and non-smokers, 2) to find out whether AI is associated with level of lactate (L). Fourteen healthy untrained smokers (≤ 1 pack year, n=7) and non-smokers (n=7) aged 18 to 26 were recruited. Each subject conducted three treadmill runs at different intensities randomly. Running distance for all three runs was equivalent to 30 minute run at 70% VO2max. AI and L were analyzed at rest (Pre), immediately after (Post), and 1 h following (1 h post) each run. Data was analyzed using two way repeated measures ANOVA. Smokers showed higher AI than non-smokers at Post in 60% (12.5±0.62% vs. 9.97±0.51, p<.008) and 70% VO2max running trials (17.53±0.57% vs. 15.6±0.41, p<.018). All L values at post showed significantly higher than Pre and 1 h post, but there was no significant difference between smokers and non-smokers. The strong positive relationship between AI and L was detected (r=.739, smokers vs. r=.793, non-smokers). Smokers tend to have higher AI than non-smokers following runs at 60% and 70% VO2max, but not following a run at 80% VO2max. An increase in AI following a run at 60% VO2max indicates that lymphocyte apoptosis can be increased following moderate intensity exercise. Since L and AI at post were increased in dose-dependent manner to exercise intensity, it is suggested that an increase in lactate production during exercise might contribute to the increase in lymphocyte apoptosis.

Abstract Evidence-based treatments (e.g. quitlines) are greatly underutilized by smokers limiting their public health impact. A three-session phone intervention for nonsmoking family members and friends (i.e. support persons) was successful for increasing smoker quitline enrollment. To enhance the intervention’s potential translatability, in this study, we delivered treatment for the non-smoker within ongoing quitline services and compared the efficacy of the three-call intervention to a streamlined version (one call). A total of 704 adult non-smokers (85% female, 95% White) wanting to help a smoker quit and recruited statewide in Minnesota participated in this randomized controlled trial with parallel groups. Non-smokers received mailed written materials and were randomly assigned to a control condition (no additional treatment, n = 235), or to a one- (n = 233) or three-call (n = 236) intervention delivered by quitline coaches. The main outcome was smoker quitline enrollment through 7-month follow-up. Smoker quitline enrollment was similar for those linked to non-smokers in the one- and three-call interventions (14.6% [34/233] and 14.8% [35/236]), and higher than for smokers linked to control participants (6.4% [15/235]), P = 0.006. Just one quitline coaching call delivered to non-smokers increased treatment enrollment among smokers. The reach of quitlines could be enhanced by targeting the social support network of smokers.

Young Adult Smokers' and Prior-Smokers' Evaluations of Novel Tobacco Warning Images.

PubMed

Healey, Benjamin; Hoek, Janet

2016-01-01

On-pack warning labels represent a very cost-effective means of communicating with smokers, who potentially see warnings each time they retrieve a cigarette. Warning labels have traditionally depicted graphic health consequences of smoking but emerging evidence suggests the distal consequences shown may prove less effective in prompting cessation among young adults. We used a novel micro-survey approach to compare novel and traditional warnings, and provide an empirical foundation for a larger study. We recruited 4649 male and 2993 female participants aged 18-34 from Google Consumer Survey's Australian panel of Android mobile phone users. A screening question resulted in a sample comprising 3183 daily, non-daily, and former smokers. Twenty images corresponding to social and health risks, tobacco industry denormalization, and secondhand smoke (SHS) were tested in paired comparisons where respondents selected the image they thought most likely to prompt cessation. Irrespective of smoking status, respondents rated messages featuring harm to children as most effective and industry denormalization messages and adult SHS warnings as least effective. Within smoker groups, daily smokers rated social concerns more highly; non-daily smokers were more responsive to SHS messages, and former smokers saw intimacy and cosmetic effects warnings as more effective than other groups. While preliminary, the findings support emerging evidence that more diverse warning images may be required to promote cessation among all smoker sub-groups. Warnings depicting harm to vulnerable others appear to hold high potential and merit further investigation. © The Author 2015.

Despite the detrimental impact of smoking on health, its prevalence remains high. Empirical research has provided insight into the many causes and effects of smoking, yet lay perceptions of smoking remain relatively understudied. The current study used a form of network analysis to gain insight into the causal attributions for smoking of both smoking and non-smoking college students. The analyses resulted in highly endorsed, complex network diagrams that conveyed the perceived causal structures of smoking.

Abstract The molecular mechanisms causing smoking‐induced health decline are largely unknown. To elucidate the molecular pathways involved in cause and consequences of smoking behavior, we conducted a genome‐wide gene expression study in peripheral blood samples targeting 18 238 genes. Data of 743 smokers, 1686 never smokers and 890 ex‐smokers were available from two population‐based cohorts from the Netherlands. In addition, data of 56 monozygotic twin pairs discordant for ever smoking were used. One hundred thirty‐two genes were differentially expressed between current smokers and never smokers (P < 1.2 × 10−6, Bonferroni correction). The most significant genes were G protein‐coupled receptor 15 (P < 1 × 10−150) and leucine‐rich repeat neuronal 3 (P < 1 × 10−44). The smoking‐related genes were enriched for immune system, blood coagulation, natural killer cell and cancer pathways. By taking the data of ex‐smokers into account, expression of these 132 genes was classified into reversible (94 genes), slowly reversible (31 genes), irreversible (6 genes) or inconclusive (1 gene). Expression of 6 of the 132 genes (three reversible and three slowly reversible) was confirmed to be reactive to smoking as they were differentially expressed in monozygotic pairs discordant for smoking. Cis‐expression quantitative trait loci for GPR56 and RARRES3 (downregulated in smokers) were associated with increased number of cigarettes smoked per day in a large genome‐wide association meta‐analysis, suggesting a causative effect of GPR56 and RARRES3 expression on smoking behavior. In conclusion, differential gene expression patterns in smokers are extensive and cluster in several underlying disease pathways. Gene expression differences seem mainly direct consequences of smoking, and largely reversible after smoking cessation. However, we also identified DNA variants that may influence smoking behavior via the mediating gene

COPD (chronic obstructive pulmonary disease) is defined by a fixed expiratory airflow obstruction associated with disordered airways and alveolar destruction. COPD is caused by cigarette smoking and is the third greatest cause of mortality in the US. Forced expiratory volume in 1 second (FEV1) is the only validated clinical marker of COPD, but it correlates poorly with clinical features and is not sensitive enough to predict the early onset of disease. Using LC/MS global untargeted metabolite profiling of serum samples from a well-defined cohort of healthy smokers (n = 37), COPD smokers (n = 41) and non-smokers (n = 37), we sought to discover serum metabolic markers with known and/or unknown molecular identities that are associated with early-onset COPD. A total of 1,181 distinct molecular ions were detected in 95% of sera from all study subjects and 23 were found to be differentially-expressed in COPD-smokers vs. healthy-smokers. These 23 putative biomarkers were differentially-correlated with lung function parameters and used to generate a COPD prediction model possessing 87.8% sensitivity and 86.5% specificity. In an independent validation set, this model correctly predicted COPD in 8/10 individuals. These serum biomarkers included myoinositol, glycerophopshoinositol, fumarate, cysteinesulfonic acid, a modified version of fibrinogen peptide B (mFBP), and three doubly-charged peptides with undefined sequence that significantly and positively correlate with mFBP levels. Together, elevated levels of serum mFBP and additional disease-associated biomarkers point to a role for chronic inflammation, thrombosis, and oxidative stress in remodeling of the COPD airways. Serum metabolite biomarkers offer a promising and accessible window for recognition of early-stage COPD. PMID:26674646

Dietary under-reporting is a common problem when using self-reported dietary assessment tools. However, there are few studies regarding under-reporting during pregnancy. This study aimed to explore the demographic and psychosocial characteristics related to dietary under-reporting in pregnant Japanese women. A cross-sectional study was conducted between 2010 and 2011 at a university hospital in Tokyo, Japan. Nutrient intake was assessed using a self-administered Diet History Questionnaire (DHQ), which had questions about the consumption frequency and portion size of selected food items. The 24-h urinary excretion levels of urea N and K were used as the dietary protein and K intake reference values, respectively. Under-reporting of protein and K was defined as the bottom 25 % of the reporting accuracy (the ratio of reported intake on the DHQ to the estimated intake based on urinary excretion). Under-reporters were defined as participants who under-reported both protein and K intake. Multiple logistic regression analysis was performed to examine the factors associated with under-reporters. Of 271 healthy women at 19-23 weeks of gestation, thirty-five participants (12·9 %) were identified as under-reporters. Under-reporters had a lower pre-pregnancy BMI (adjusted OR (AOR) = 0·81) and lower gestational weight gain (AOR = 0·82); they also reported managing their gestational weight gain with the aim to return to their pre-pregnancy weight soon after childbirth (AOR = 2·99). Healthcare professionals should consider the potential for dietary under-reporting and the possible related factors when assessing the dietary intakes of pregnant Japanese women using self-administered questionnaires.

Social networks influence health behavior, including tobacco use and cessation. To date, little is known about whether and how the networks of online smokers and non-smokers may differ, or the potential implications of such differences with regards to intervention efforts. Understanding how social networks vary by smoking status could inform public health efforts to accelerate cessation or slow the adoption of tobacco use. These secondary analyses explore the structure of ego networks of both smokers and non-smokers collected as part of a randomized control trial conducted within Facebook. During the trial, a total of 14,010 individuals installed a Facebook smoking cessation app: 9,042 smokers who were randomized in the trial, an additional 2,881 smokers who did not meet full eligibility criteria, and 2,087 non-smokers. The ego network for all individuals was constructed out to second-degree connections. Four kinds of networks were constructed: friendship, family, photo, and group networks. From these networks we measured edges, isolates, density, mean betweenness, transitivity, and mean closeness. We also measured diameter, clustering, and modularity without ego and isolates. Logistic regressions were performed with smoking status as the response and network metrics as the primary independent variables and demographics and Facebook utilization metrics as covariates. The four networks had different characteristics, indicated by different multicollinearity issues and by logistic regression output. Among Friendship networks, the odds of smoking were higher in networks with lower betweenness (p = 0.00), lower transitivity (p = 0.00), and larger diameter (p = 0.00). Among Family networks, the odds of smoking were higher in networks with more vertices (p = .01), less transitivity (p = .04), and fewer isolates (p = .01). Among Photo networks, none of the network metrics were predictive of smoking status. Among Group networks, the odds of smoking were higher when diameter

Tobacco use is growing quickly in the developing countries. International tobacco companies often escape the strict labeling laws of their national origins by operating in developing societies where such laws are lacking. Bangladesh is a prime example of a developing society where tobacco use and its subsequent social costs are increasing. A survey of Bangladeshis in the capital city of Dhaka shows that both smokers and non-smokers believe public programs aimed at educating the public on the dangers of tobacco use should be implemented. Schools were seen as a viable medium for educating the young. Government warnings concerning any dangers were mandated by both smokers and non-smokers. Limitations on where persons would be allowed to smoke was seen as a viable government policy by the respondents. A promising finding was that the more aware a person was of the dangers of tobacco consumption, the less likely the person was to use tobacco. Implications for government policy makers are discerned.

The objective of this project was to determine the relationship between cigarette smoking and the reporting of chronic pain syndromes among participants in the Kentucky Women's Health Registry. Data was analyzed on 6,092 women over 18 years of age who responded to survey questions on pain and smoking. The chronic pain syndromes included in the analysis were fibromyalgia, sciatica, chronic neck pain, chronic back pain, joint pain, chronic head pain, nerve problems, and pain all over the body. Analyses controlled for age, body mass index, and Appalachian versus non-Appalachian county of residence. Results showed that women who were daily smokers reported more chronic pain (defined as the presence of any reported chronic pain syndromes) than women who were never smokers (adjusted odds ratio [aOR] = 2.04 and 95% confidence interval [CI] 1.67, 2.49). An increased risk was also seen for "some-day" smokers (aOR 1.68, 95% CI 1.24, 2.27), and former smokers (aOR 1.20, 95% CI 1.06, 1.37), though with less of an association in the latter group. This study provides evidence of an association between chronic pain and cigarette smoking that is reduced in former smokers. This paper presents the association between smoking and musculoskeletal pain syndromes among Kentucky women. This finding may provide additional opportunities for intervention in patients with chronic pain. Copyright © 2011 American Pain Society. Published by Elsevier Inc. All rights reserved.

Schizophrenia and bipolar disorder show high comorbidity with smoking dependence. Several previous studies reported that glycogen synthase kinase 3β (GSK3β), which is widely expressed in the brain including the dopamine projection areas such as the amygdala, nucleus accumbens and hippocampus, may play a role in neuropsychiatric disorders and dopamine- and serotonin-mediated behavior. In this study, we have analyzed the association of three single nucleotide polymorphisms (SNPs) within GSK3β gene (rs3755557, rs334558, rs6438552) with the smoking habits and age at smoking initiation in a sample of 384 young adult Japanese, which included 172 smokers and 212 non-smokers. As a result, rs334558 was significantly associated with smoking habits in genotype frequency and allelic frequency (P < 0.05). Furthermore, higher haplotype 3 (T-T-T) and haplotype 5 (A-T-C) frequencies were observed in non-smokers than smokers (P < 0.05). Three functional polymorphisms examined in this study reportedly increase transcriptional activity when they have a high-activation allele such as the A allele of -1727A/T (rs3755557), the T allele of -50T/C (rs334558) or T allele of -157T/C (rs6438552). Thus, it was suggested in this study that changes in GSK3β activity may have an impact on smoking habits.

Cigarette smoking is a behavior, which is influenced by genetic, demographic, and psychological factors. A large body of research has examined the association of cigarette smoking variables with individual differences in personality traits. The aim of the current study was to replicate the findings of higher self-reported impulsivity in smokers compared with never-smokers in a German sample using Eysenck´s construct of impulsivity. Furthermore, it was intended to further the knowledge about associations between different self-reported impulsivity components and different smoking variables. We used the Impulsiveness-Venturesomeness-Empathy questionnaire (I7) to measure self-reported impulsiveness and venturesomeness and the Temperament and Character Inventory (TCI) to measure novelty seeking (NS) in a sample of 82 nicotine-dependent smokers and 119 never-smokers. Smokers scored higher on impulsiveness, venturesomeness, and NS than never-smokers independent of age, gender, and years of education. We found a significant association between venturesomeness, impulsiveness and smoking status in daily smokers. In summary, this study provides evidence that impulsiveness and venturesomeness as well as the novelty-seeking subscale extravagance are significantly associated with smoking status in a German sample of female and male smokers compared with never-smokers.

The affordability of food is considered as an important factor influencing people's diet and hence health status. The objective of this cross-sectional study was to test the hypothesis that neighborhood food store availability is associated with some aspects of dietary intake and thus possibly with body mass index (BMI) and waist circumference in young Japanese women. Subjects were 989 female Japanese dietetic students 18 to 22 years of age. Neighborhood food store availability was defined as the number of food stores within a 0.5-mile (0.8-km) radius of residence (meat stores, fish stores, fruit and vegetable stores, confectionery stores/bakeries, rice stores, convenience stores, and supermarkets/grocery stores). Dietary intake was estimated using a validated, comprehensive self-administered diet history questionnaire. No association was seen between any measure of neighborhood food store availability and dietary intake, except for a positive association between confectionery and bread availability (based on confectionery stores/bakeries, convenience stores, and supermarkets/grocery stores) and intake of these items (P for trend = .02). Further, no association was seen for BMI or waist circumference, except for an inverse relationship between availability of convenience stores and BMI and a positive relationship between store availability for meat (meat stores and supermarkets/grocery stores) and fish (fish stores and supermarkets/grocery stores) and waist circumference. In conclusion, this study of young Japanese women found no meaningful association between neighborhood food store availability and dietary intake, BMI, or waist circumference, with the exception of a positive relationship between availability and intake for confectionery and bread.

Smoking risk and the likelihood of quitting among African-American female light and heavy smokers.

While African-American females are more likely to be light smokers compared to their counterparts of other racially classified social groups (RCSGs), they are more likely to carry a heavier burden of smoking-related morbidity and mortality. Thus, it is critical that African-American female light smokers are targeted to engage in smoking cessation. Research has revealed that African-American women are less likely to have a successful quit attempt following a cessation intervention than females from other RCSGs. It has been postulated that the low smoking cessation rates among African-American female light smokers may be due to the lack of appropriate psychosocioculturally tailored cessation interventions that address issues of stress and coping that explain why they smoke and continue to smoke that may differ from their heavy smoker counterparts. The purpose of this study was to ascertain whether African-American female light smokers differed from their heavy smoker counterparts on psychosociocultural stress and coping factors. Findings revealed no differences in the sociodemographic variables of age, income, education and BMI; in the psychosociocultural measures of acculturative stress, race-related stress and coping; or in the smoking characteristics of menthol smoking status, cotinine level and CYP2A6 metabolic functioning between light and heavy smokers. However, the study found that African-American female light smokers take longer to smoke their first cigarette of the day, have a lower smoking risk, are more likely to quit, and exhibit lower carbon monoxide levels than African-American female heavy smokers. The current study suggests that other than the obvious factors of greater likelihood of quitting, lower smoking risk, longer latency to smoke and lower carbon monoxide levels, specific smoking cessation programs may not need to be differentially psychosocio-culturally tailored for African-American female light smokers compared to their heavy

Adolescent cigarette smokers' and non-cigarette smokers' use of alternative tobacco products.

Saunders, Charles; Geletko, Karen

2012-08-01

This study uses the most recent data from the nationally representative National Youth Tobacco Survey (NYTS) to examine the use of alternative tobacco products among U.S. cigarette smokers and non-cigarette smokers aged 14-17. Alternative tobacco product use is defined as use of one or more of the following products: smokeless tobacco, cigars, pipes, bidis, or kreteks. Using the results from the 2004, 2006, and 2009 NYTS, multivariate logistic regressions were used to investigate separately the extent of alternative tobacco product use in current cigarette smokers and in those who reported not smoking cigarettes controlling for demographic and other independent influences. The results indicate that for adolescent smokers and nonsmokers, the use of one type of alternative tobacco product made it much more likely the individual would use one or more of the other alternative tobacco products. Non-cigarette smokers using these tobacco products appeared to exhibit symptoms of nicotine dependence comparable to those of cigarette smokers. More information on adolescent use of alternative tobacco products is needed. Current cigarette use declined 3.4% annually over 2004-2009 for the NYTS 14- to 17-year-old population, but this cohort's use of alternative tobacco products was unchanged. The number of adolescents aged 14-17 who did not smoke cigarettes but used alternative tobacco products increased 5.9% per year over the same period. Current surveillance measures need to be expanded in order to gain a more comprehensive understanding of adolescent alternative tobacco use.

Delay and probability discounting of multiple commodities in smokers and never-smokers using multiple-choice tasks.

2013-12-01

The purpose of the present study was to investigate temporal and probabilistic discounting in smokers and never-smokers, across a number of commodities, using a multiple-choice method. One hundred and eighty-two undergraduate university students, of whom 90 had never smoked, 73 were self-reported light smokers (<10 cigarettes/day), and 17 were heavy smokers (10+cigarettes/day), completed computerized batteries of delay and probability discounting questions pertaining to a total of eight commodities and administered in a multiple-choice format. In addition to cigarettes, monetary rewards, and health outcomes, the tasks included novel commodities such as ideal dating partner and retirement income. The results showed that heavy smokers probability discounted commodities at a significantly shallower rate than never-smokers, suggesting greater risk-taking. No effect of smoking status was observed for delay discounting questions. The only commodity that was probability discounted significantly less than others was 'finding an ideal dating partner'. The results suggest that probability discounting tasks using the multiple-choice format can discriminate between non-abstaining smokers and never-smokers and could be further explored in the context of behavioral and drug addictions.

To describe the smoking prevalence by key socio-demographic characteristics (age, gender, ethnicity, education, labour status, income and socioeconomic deprivation) in New Zealand in 2013 and make comparisons with 2006. Data on cigarette smoking and key socio-demographics variables were obtained from the 2013 New Zealand Census of Population and Dwellings. Age standardised smoking prevalence rates were calculated by gender, ethnicity and socioeconomic deprivation using the WHO Population Standard. Results were compared against 2006 Census data to identify changes in smoking prevalence. In 2013, around one in seven (15.1%) of New Zealand adults aged 15 years and older reported that they were regular smokers (smoked one or more cigarettes per day), a 5.6% absolute decrease in the smoking prevalence since the previous Census in 2006. The number of regular adult smokers dropped from 597,792 in 2006 to 463,194 in 2013, a 22.5% decrease. Falls in smoking prevalence occurred among all demographic sub-groups, including Māori and young adults. There were substantial disparities in smoking by age, ethnicity and socio-economic status. Māori continue to have the highest age-standardised smoking prevalence (32.4%), with the highest prevalence (43.1%) among young Māori women aged 25 to 29 years. Decreases in smoking prevalence were greater between 2006 and 2013 than between 1996 and 2006. The findings suggest that the decline in smoking prevalence is accelerating in New Zealand, including among high priority groups like Māori, Pacific peoples and young adults. This study confirms the value of census data for understanding patterns of tobacco use in New Zealand, to inform effective intervention development and monitoring progress towards the Smokefree 2025 goal.

Non-fasting triglycerides were reported to have a greater impact on risk of ischemic cardiovascular events than fasting triglycerides. However, evidence from Asia, where the prevalence of dyslipidemia is generally lower, has been limited. We used 1975-1986 baseline surveys to investigate cohort data of 10,659 (4264 men and 6395 women) residents aged 40-69 years, initially free from ischemic heart disease and stroke, in four Japanese communities. Serum triglyceride concentrations at baseline were obtained for 2424 fasting (≥8 h after meal) and 8235 non-fasting (<8 h after meal) participants. During the 22-year follow-up, 284 (165 men and 119 women) developed ischemic heart disease and 666 (349 men and 317 women) ischemic stroke. After adjustment for age, sex and known cardiovascular risk factors, multivariable hazard ratios (95%CI) of ischemic cardiovascular disease (ischemic heart disease and ischemic stroke) for the highest versus lowest quartiles of triglycerides were 1.71 (1.14-2.59), P for trend = 0.013, for fasting participants and 1.60 (1.25-2.05), P for trend <0.001, for non-fasting participants. The positive associations did not differ between fasting and non-fasting men, while they were strong for non-fasting women. They were stronger for ischemic heart disease than for ischemic stroke. After further adjustment for HDL-cholesterol, these associations were slightly attenuated, but remained statistically significant. Non-fasting as well as fasting triglycerides are predictive of risk of ischemic cardiovascular disease for Japanese men, as are non-fasting triglycerides for women. Copyright © 2014.

Breast cancer is the most common cancer in women. However, it remains unproven whether psychological factors have an influence on breast cancer incidence. In our earlier study, subjects possessing two personality traits, decisiveness and “ikigai” (a Japanese word meaning something that makes one’s life worth living), showed a significantly lower risk of developing breast cancer, although no psychological factors have been convincingly demonstrated to have an influence on breast cancer development in other studies. Therefore, we conducted this follow-up analysis to confirm the association between breast cancer incidence and psychological traits, using the final dataset of a large-scale prospective cohort study in Japan. We identified 209 cases of incident breast cancer out of a maximum 21-year follow-up of 29,098 Japanese women. Cox proportional hazard regression analysis, adjusted for the same potential confounders used in our previous study, did not reveal any significant relationships between breast cancer incidence and four psychological traits: having “ikigai”, decisiveness, ease of anger arousal, and perceived stress. Our finding is consistent with previous studies, and suggests that the psychological traits are unlikely to be an important risk factor for breast cancer. PMID:27586560

Background and Objectives: Prevention of the periodontal disease progression is the primary goal of periodontal therapy. When conventional therapy is found inadequate to attain periodontal health in chronic periodontitis, local antimicrobial agents have been used as an adjunct with scaling and root planning (SRP) which has reproduced encouraging results. Hence, this study was undertaken to evaluate the new sustained released local drug Chlosite clinically and microbiologically in smokers and non-smokers. Materials and Methods: The patients were grouped into experimental group A treated with SRP plus Chlosite (SRP + CHL), experimental group B treated with Chlosite alone (CHL), and control group C treated only with SRP alone. A total number of 141 sites from six patients (67 sites from three non-smoker patients and 74 sites from three smoker patients) participated in this study. The clinical parameters, Plaque index (PI), Gingival index (GI), Bleeding index (BI), and Relative attachment level (RAL), were recorded and subgingival plaque samples were collected and subjected to microbiological analysis. Results: On comparison of smokers and non-smokers, in SRP group, non-smokers showed a higher reduction in BI and GI and smokers showed a higher reduction in PI. There was no significant gain in RAL of both smokers and non-smokers. In SRP + CHL group, non-smokers showed a higher reduction in relation to BI and GI and smokers showed a higher reduction in relation to PI. There was no significant gain in RAL of both smokers and non-smokers. In CHL group, both smokers and non-smokers showed a nonsignificant reduction in BI, GI, and RAL, but smokers showed a significant reduction in PI as compared with non-smokers. All the groups showed reduction in the microbial count of Fusobacterium nucleatum, Porphyromonas gingivalis, and Tannerella forsythia which were found to be statistically not significant when it was compared between non-smokers and smokers.
