RESUMEN
BACKGROUND: Recent innovations in information and communication technology have made it possible to assess diet using web-based methods; however, their applicability in the general population remains unclear. Hence, we aimed to examine the applicability of a web-based 24-hour dietary recall (24HR) tool to large-scale epidemiological studies by determining the sampling rate and characteristics of randomly selected participants from a Japanese cohort study. METHODS: In total, 5,013 individuals were recruited from a cohort of 21,537 individuals, and 975 agreed to participate in this study. The participants selected either self-administered web-based dietary 24HR (self-administered 24HR) or interviewer-administered telephone-based 24HR (interviewer-administered 24HR) as the method for the dietary assessment and answered questions regarding the acceptability of the system. RESULTS: The response rate of the 975 participants was 19.4%, corresponding to approximately 4.5% of the total study sample. About half of them chose the self-administered 24HR (46.9%). The median time required for the self-administered and interviewer-administered 24HR was 25 and 27 minutes, respectively. In the self-administered 24HR, older people, regardless of sex, tended to require a longer time, and approximately 60% of the participants rated the ease of use of the system as "somewhat difficult" or "difficult." CONCLUSION: Characteristics of the participants in this study were not systemically different from those of the entire study sample. Improvements in the approach to entering cooking details and the dish name selection may be necessary for better acceptability in order to be accepted as a self-administered dietary recall tool.

BACKGROUND: There is limited evidence regarding the relationship between Diabetes mellitus (DM) in middle age and mild cognitive impairment after a follow-up. Therefore, we investigated the relationship between fasting blood glucose (FBG) levels in middle age and cognitive function assessed using the Japanese version of the Montreal Cognitive Assessment (MoCA-J) in later life, following over 15 years of follow-up in the Aichi Workers' Cohort Study in Japan. METHODS: Participants were 253 former local government employees aged 60-79 years in 2018 who participated in a baseline survey conducted in 2002. Using baseline FBG levels and self-reported history, participants were classified into the normal, impaired fasting glucose (IFG) and, and DM groups. Total MoCA-J score ranges from 0 to 30, and cognitive impairment was defined as MoCA-J score ≤25 in this study. A general linear model was used to estimate the mean MoCA-J scores in the FBG groups, adjusted for age, sex, educational year, smoking status, alcohol consumption, physical activity, body mass index, systolic blood pressure, total cholesterol, and estimated glomerular filtration rate. RESULTS: The mean MoCA-J score in the total population was 25.0, and the prevalence of MoCA-J score ≤25 was 49.0%. Multivariable-adjusted total MoCA-J scores were 25.2, 24.8, and 23.4 in the normal, IFG, and DM groups, respectively. The odds ratio of MoCA-J score ≤25 in the DM group was 3.29. CONCLUSION: FBG level in middle age was negatively associated with total MoCA-J scores assessed later in life, independent of confounding variables.

BACKGROUND: Pacific islanders face drastic increase of obesity-related noncommunicable disease (NCD) due to lifestyle shifts of unhealthy diets and physical inactivity. To date, however, obesity related factors have not been well elucidated in Republic of Palau. This study aimed to investigate sociodemographic and behavioral factors related to obesity using the national level data in Palau. METHODS: This is a cross-sectional, population-based study analyzing random sampling data of 2133 adults aged 25-64 years (of 20 thousand national population) from the WHO STEPwise approach to NCD risk factor surveillance (STEPS) implemented between 2011 and 2013. Sociodemographic and behavioral factors were obtained by the STEPS standardized questionnaire for NCD risk factors plus the question on betel nut chewing because of its common behavior in Micronesian countries. Logistic regression analysis was performed to estimate multivariable odds ratio (OR) of general obesity (body mass index ≥30.0 kg/m2) and central obesity (waist circumference ≥90 cm in men and ≥80 cm in women). RESULTS: Means of body mass index, prevalence of general obesity and central obesity were higher in women (29.9 kg/m2, 45.5% and 85.4%) than in men (29.3 kg/m2, 40.4% and 67.6%). After adjusted by other potential factors, native Palauan (OR 4.4, 95% CI, 2.7-7.0 for men and 3.6, 2.3-5.6 for women), betel nut chewing (1.5, 1.1-2.1 for men and 1.6, 1.2-2.3 for women), men who work at government office (1.6, 1.2-2.1), women with higher household income (1.4, 1.0-1.8) were positively associated with general obesity, while frequent vegetable intake were inversely associated with it among women (0.71, 0.54-0.93). Similar associations were observed between the aforementioned factors and central obesity. CONCLUSIONS: Native Palauan, people with betel nut chewing behavior, government employment and higher income appeared to be associated with obesity, while frequent vegetable consumption were inversely associated with obesity. Further interventions for prevention and control of obesity are necessary through the enhancing public relation activities to understand harmful health effects on betel nuts chewing and recommending domestic production of vegetables.

BACKGROUND: This study aimed to describe the status of alcohol consumption and drug use among young adults as well as their determinants. METHODS: We conducted a cross-sectional study of 356 young adults (aged 18 to 24 years) living in Palau in 2013. The prevalence of self-reported alcohol and marijuana usage were compared within and between sexes, age groups, ethnicities, and education levels. RESULTS: The proportion of current drinking was higher in people aged 21-24 than in those aged 18-20 (73.2% vs. 60.9%, p = 0.09 in men and 48.3% vs. 30.0%, p = 0.02 in women), while that of marijuana use did not differ between the age groups. The proportions of current drinking and marijuana use were higher in Palauan than in other ethnicities (current drinking: 70.6% vs. 40.6%, p = 0.005 in men and 38.8% vs. 16.6%, p = 0.04 in women; lifetime marijuana use: 80.0% vs. 52.9%, p = 0.02 in men and 56.1% vs. 30.6%, p = 0.09 in women). The proportion of frequent (3 times or more) marijuana users was higher for the lower educated than for the higher educated (62.5% vs. 32.1%, p < 0.001 in men and 33.9% vs. 24.4%, p = 0.12 in women). CONCLUSIONS: Sex, age, ethnicity, and education were significant determinants of alcohol and marijuana use.

Our previous epidemiological survey targeting urban slum dwellers in Bangladesh showed that the prevalence of diabetes defined by glycated haemoglobin (HbA1c) was higher than the national estimation, and higher in women than men. Subsequently, we conducted the oral glucose tolerance test (OGTT) and found that HbA1c values were consistent with the OGTT findings for detecting diabetes. Our findings indicated that HbA1c ≥6.5% was a rational cut-off, but the optimal HbA1c cut-off for this population might be lower than the internationally recommended threshold. Measuring HbA1c would be a reliable and feasible option for detecting diabetes among underprivileged population in developing countries.

BACKGROUND: The aim of the present study was to comprehensively investigate the meaning and practices of spiritual care for older people with dementia based on the perspective and experiences of nurses and care workers. METHODS: The study was designed according to qualitative research strategies and used face-to-face interview data, with a focus on the experiences of nurses and care workers who care for elderly persons with dementia. Five nurses and 13 care workers from nine care facilities participated. We conducted 10 interviews, each with one to three participants, from April to August 2017. An open-ended questionnaire concerning the meaning and practices of spiritual care for older people with severe dementia was used to comprehensively capture the participants' experiences of caring for older people with dementia. Qualitative content analysis was used to systematically identify ideas and patterns emerging from the qualitative data. RESULTS: Three main themes emerged from the qualitative analysis of what constituted spiritual care for older people with dementia: (i) self-esteem; (ii) communication; and (iii) individual difference. CONCLUSIONS: Nurses and care workers perceived self-esteem as a core domain of spiritual care for older people with severe dementia. Reminiscing about important achievements and enjoying small pleasures in daily life enhance older people's self-esteem. Communication strategies involving active listening and therapeutic lying can help maintain older people's self-esteem and cognitive abilities. Older people with dementia respond in different ways to standardized care procedures, so care providers must employ of a variety of skilful approaches.

PURPOSE: Gut microbiota composition was supposedly related to obesity and psychological factors. We examined the effects of a nutritional education intervention focusing on gut microbiota composition on obesity and psychological factors among obese women. METHODS: Forty-four obese Japanese women aged 40 or older were randomly assigned to either an intervention group (n = 22) or control group (n = 22). The intervention consisted of a 20-min dietary lecture and a 10-min counselling session by registered dieticians, every 2 weeks for eight consecutive weeks. Body weight, height, waist circumference, food frequency, and gut microbiota composition were measured, and self-rated health and psychological factors were scored before and after the intervention. RESULTS: All participants completed the 8 week program. After the intervention, dietary fibre intake (p < 0.01), frequency of vegetable consumption (p = 0.020), and frequency of milk and milk product consumption (p < 0.01) increased significantly in the intervention group compared with the control group. Body weight and body mass index (BMI; p < 0.001), waist circumference (p < 0.01), and the depression scale score (p < 0.01) decreased significantly, while significant improvements were found in self-rated health (p = 0.045) and microbiome diversity (p < 0.01). CONCLUSION: Nutritional education focusing on gut microbiota composition may improve obesity and psychological factors in obese women.

BACKGROUND: Epidemiological evidence of dyslipidemia in Pacific Island countries is limited despite the knowledge that non-communicable diseases have a high burden in the region. We aimed to examine the prevalence and correlates of dyslipidemia among residents of Palau. METHODS: The Palau STEPwise approach to Surveillance (STEPS), which was conducted from 2011 through 2013, comprised three parts: behavioral risk factors; physical measurements; and biochemical tests, covering areas such as blood lipids. We used STEPS-generated data to perform a cross-sectional study of 2,184 randomly selected Palau residents, comprising Palauans and non-Palauans aged 25-64 years. RESULTS: The age-adjusted mean BMI was 29.3 kg/m2 in men and 29.9 kg/m2 in women; age-adjusted mean triglycerides value was 182 mg/dL in men and 166 mg/dL in women; and age-adjusted mean cholesterol was 178 mg/dL in men and 183 mg/dL in women. The prevalence of overweight/obesity (BMI ≥25 kg/m2) was 75% in men and 76% in women, and those of hypertriglyceridemia (triglycerides ≥150 mg/dL) and hypercholesterolemia (total cholesterol ≥200 mg/dL) were 48% in men and 41% in women and 18% in men and 23% in women, respectively. Mean values of total cholesterol were 177 mg/dL in Palauan men and 182 mg/dL in non-Palauan men. Mean values of triglycerides were 171 mg/dL in Palauan women and 150 mg/dL in non-Palauan women. Women living in rural areas showed a higher mean value of total cholesterol than those in urban areas. CONCLUSION: We found a high mean BMI and high prevalence of overweight/obesity and hypertriglyceridemia, but low mean total cholesterol and a low prevalence of hypercholesterolemia in Palau. Lipid profiles varied by age, ethnicity, and living area.

The aim of this study is to identify key challenges to successful community-based integrated team approach to the management of older adults with dementia. A nationwide community-based qualitative research strategy was applied. We purposively recruited 24 health-care providers and 13 family caregivers from selected 8 prefectures among 47 prefectures. Face to face interviews were conducted from May to September 2017. Qualitative content analysis was used to analyze the qualitative data. Ten themes regarding the challenges were emerged: Ignored wishes, Family caregivers' full responsibilities, Encouragement, Practical and easy-to-understand information, Essential skills of dementia diagnosis and assessment, Gratitude by helping others, Difference between being kind and overly-kind, Legal barrier against information sharing, Coordination between volunteers and clients, and Conflict avoidance in multidisciplinary collaboration. The findings highlight the need to provide practical and easy-to-understand information for family caregivers, educate physicians in dementia diagnosis and assessment, share personal dementia care information among health-care providers, promote platforms which aim to match dementia care volunteers with older adults with dementia and their families in need of help, and raise awareness of advance care planning among both older individuals and health-care providers.

BACKGROUND: Relatively little evidence exists for type 2 diabetes mellitus (T2DM) prediction models from long-term follow-up studies in East Asians. This study aims to develop a point-based prediction model for 10-year risk of developing T2DM in middle-aged Japanese men. METHODS: We followed 3,540 male participants of Aichi Workers' Cohort Study, who were aged 35-64 years and were free of diabetes in 2002, until March 31, 2015. Baseline age, body mass index (BMI), smoking status, alcohol consumption, regular exercise, medication for dyslipidemia, diabetes family history, and blood levels of triglycerides (TG), high density lipoprotein cholesterol (HDLC) and fasting blood glucose (FBG) were examined using Cox proportional hazard model. Variables significantly associated with T2DM in univariable models were simultaneously entered in a multivariable model for determination of the final model using backward variable selection. Performance of an existing T2DM model when applied to the current dataset was compared to that obtained in the present study's model. RESULTS: During the median follow-up of 12.2 years, 342 incident T2DM cases were documented. The prediction system using points assigned to age, BMI, smoking status, diabetes family history, and TG and FBG showed reasonable discrimination (c-index: 0.77) and goodness-of-fit (Hosmer-Lemeshow test, P = 0.22). The present model outperformed the previous one in the present subjects. CONCLUSION: The point system, once validated in the other populations, could be applied to middle-aged Japanese male workers to identify those at high risk of developing T2DM. In addition, further investigation is also required to examine whether the use of this system will reduce incidence.

Successful advance care planning relies heavily on effective communication between the elderly and their families, care managers, and social workers. However, care managers and social workers are often not adequately prepared to conduct such discussion. The aim of the present study was to identify the specific challenges facing Japanese care managers and social workers when involvement in advance care planning. Two focus group discussions were held between August and November 2017, involving eleven care managers and three social workers employed at two long-term care facilities actively pursuing advance care planning initiatives. Four main themes were identified, through content analysis, as barriers and facilitators: client readiness, communication, variation-rich client individuality, and difficult-to-explain end-of-life options. This study revealed the importance of building rapport with the residents and their families in order to assess their readiness to discuss care options and preferences. Obstacles included lack of medical knowledge of care managers and social workers. Study findings suggested that a multi-disciplinary team, facilitated by care managers and social workers, was fundamental to achieving the goals of advance care planning.

Objectives The Maternal and Child Health (MCH) handbook is an integrated home-based record allowing clients to keep records on the continuum of care for mothers and children. This study aimed to assess associations between MCH handbook ownership and receipt of selected content of antenatal care services in Palestine. Methods Distribution of the MCH handbook in Palestine was launched in 2008. We used an anonymous data set of the Palestinian Family Survey 2010 and analyzed the data of 2026 women who had live births within the past 12 months. Descriptive statistical analysis was conducted to assess differences between MCH handbook holders and non-holders. Multivariable logistic regression models were used to estimate adjusted odds ratios of the effects of MCH handbook use according to proxy indicators of antenatal care quality. Results Accounting for about 60% (n = 1202) of study participants, handbook holders were more likely to be primipara, live in the Gaza Strip, live in refugee camps, and live within a 30-min distance to antenatal care facilities; however, household wealth levels for handbook holders were lower compared with non-holders. Handbook users had significantly higher odds of receiving all three kinds of medical tests and receiving information on five or more health education topics as part of antenatal care. The higher odds remained after adjusting for possible confounding variables, such as household wealth, region, residential area, birth order of the child, frequency of antenatal care, and time required to reach antenatal care facilities. Conclusions for Practice Use of the handbook as a portable checklist possibly promoted providers' higher adherence to the national guideline.

Although one of the most important missions of end-of-life education is to ensure proper inter-professional education (IPE), in Japan, end-of-life care IPE has not been given enough attention especially in community settings. This study aims at developing an effective workshop facilitator training program on end-of-life care IPE and acquiring the know-how to set up and efficiently run administrative offices. We first developed a tentative facilitation training program and conducted it in five cities nationwide. The training strategy was as follows: (1) participating in the workshop, (2) attending a lecture on facilitation, (3) conducting a preparatory study, (4) attending one workshop session as a facilitator, and (5) reflecting on one's attitude as a facilitator based on workshop participants' questionnaire, peer-feedback, and video recording. A total of 10 trainees completed the training program. We assessed the level of improvement in the trainees' facilitation skills and the efficacy of the training course using a qualitative approach. This formative study helped us identify several aspects needing improvement, especially in the areas of information technology and social media. Progress in these areas may have a positive impact on the education of community health care professionals whose study hours are limited, helping provide continued facilitation training.

Non-communicable diseases have been recognized as a serious threat to public health in Palau. To tackle the problem, different strategies might be necessary for populations with different ethnic backgrounds. This study aims to find the differences in the prevalence of metabolic risk factors of non-communicable diseases between Palauans and Filipinos living in Palau, and examine possible determinants of the differences. We selected data of 2,032 participants, including native Palauans and Filipinos, from the Palau STEPS Survey 2011-2013 for this study. Logistic regression models were used to inspect the association of each metabolic risk factor with ethnicity by calculating odds ratios adjusted for potential confounding factors. Palauans had higher age-standardized prevalence of overweight or obesity (84% vs. 45%), hypertension (50% vs. 38%) and diabetes (19% vs. 13%) than Filipinos. However, after adjusting for BMI and various lifestyle related factors, there are no statistical significant differences in the prevalence of hypertension and diabetes between these two ethnic groups. Palauan men were less likely to have elevated total cholesterol, especially after adjusting for BMI (odds ratio=0.55, 95% confidence interval: 0.33-0.91), while Palauan women were more likely to have elevated triglycerides than their Filipino counterparts (odds ratio=1.45, 95% confidence interval: 1.02-2.06). Our findings suggested that Palauans' higher BMI distribution might be able to explain their higher prevalence of hypertension and partially explain their higher diabetes prevalence. Palauans were not consistently more likely to have all metabolic risk factors, namely dyslipidemia were less likely to be observed in Palauan men.

OBJECTIVES: A population survey was conducted in an urban shantytown in Bangladesh, as a baseline study of future epidemiological studies. This paper aims to describe the findings of the study, including the population profile and residential environment of the urban poor. METHODS: We conducted a complete count household survey in an urban poor community in Dhaka. Using a brief structured questionnaire in Bengali language, trained interviewers visited each household and asked questions such as: duration of residence; ownership of house, toilet and kitchen; water supply; number of family members; age, sex, education, occupation, tobacco use, and history of diseases of each family member. RESULTS: We found that there were 8604 households and 34,170 people in the community. Average number of household members was 4.0. Most people had access to safe water, but only 16% lived in the house with a toilet. Based on the proxy indicators of household wealth levels, we identified that about 39% were relatively well-off, while the rest were very poor. Tobacco use was prevalent in men regardless of age and in women aged over 35 years. Prevalence of self-reported hypertension and diabetes was slightly higher in women than in men, although over 70% of the respondents didn't know if they had such diseases. Incidences of diarrhea in the last one month were relatively low. CONCLUSIONS: The study showed population profile and sanitation environment in an urban poor community by a complete count survey. We expect the study to serve as a baseline for future epidemiological studies.

Non-communicable diseases (NCDs) are the major public health concerns in China. However, little has been known yet about the background social factors that influence lifestyles as possible NCD risk factors. This qualitative study aimed to explore facilitators and barriers of adopting healthy lifestyles among residents in a rural community of China. Three age-stratified focus group discussions (FGDs) were conducted in Fangshan district of Beijing in 2013. A FGD guide was designed to elicit the participants' perception and experience regarding their lifestyles. The audio-records were transcribed, and data were qualitatively analyzed through thematic approach. Through social capital framework with bonding, bridging, and linking classifications, we identified the following facilitators and barriers to adopt healthy lifestyles. (1) Facilitators: mutual support from family/friends and motivation to participate in regular exercises (bonding); cooperative relationships with community health workers (bridging); and nationwide high level of healthy lifestyle awareness (linking). (2) Barriers: negative influence from family/friends, insufficient support from family/friends, peer pressure and tolerance towards unhealthy lifestyles (bonding); insufficient support from health professionals (bridging); and inequity in allocation of public resources (linking). This study revealed that bonding, bridging and linking social capital would work as facilitators and barriers to adopt healthy lifestyles among rural residents in China.

We aimed to investigate the prevalence and predictors of diabetes and prediabetes among adults in Palau. We used data of 1915 adults, aged 25 to 64 years, who participated in the World Health Organization's (WHO) STEPwise Approach to Risk Factor Surveillance (STEPS) study in Palau. Information on behavioral risk factors of NCDs and physical and biochemical measurements were obtained using standard methods of the WHO. The diagnosis of diabetes and prediabetes was based on the recent American Diabetes Association criteria. Predictors of the prevalence of diabetes and prediabetes were identified using multinomial logistic regression analysis. The overall age-standardized prevalence of prediabetes and diabetes were 40.4% (43.6% for men, 37.4% for women) and 17.7% (18.6% for men, 17% for women), respectively. Old age, overall obesity (high BMI), central obesity (large waist circumference or waist-hip ratio), hypertension and hypertriglyceridemia were significant predictors of prediabetes and/or diabetes. Diabetes occurred at a younger age in "obese" individuals than that of their "non-obese" counterparts. We confirmed that prediabetes and diabetes are highly prevalent in Palau affecting 40% and 18% adults, respectively. Introducing public health interventions to reduce and prevent obesity as early as possible could prove useful to curb the problem.
RESUMEN
OBJECTIVE: To investigate differences in the association of parental history of diabetes with the risk of type 2 diabetes mellitus (T2DM) in the offspring according to the sex of the parent and the offspring's body weight. METHODS: A prospective cohort study of 4446 middle-aged non-diabetic Japanese men and women were followed in Aichi Prefecture, central Japan, from 2002 to 2011. Subjects were categorized by their self-reported parental history of diabetes ("no parental history," "father only," "mother only," and "both"). The association of parental history of diabetes and incidence in the offspring was examined according to overweight status adjusted for age, sex, birth weight, smoking, alcohol consumption, physical activity, total energy intake, body mass index, and number of metabolic syndrome components. RESULTS: During follow-up (median 8.9 years), 277 subjects developed T2DM. Parental history of diabetes was positively associated with T2DM incidence. However, stratified analysis by overweight status revealed that only maternal history was associated with increased T2DM incidence in non-overweight subjects (hazard ratio=2.35, 95% confidence interval: 1.41-3.91). While in overweight subjects, paternal history was significantly associated with higher T2DM incidence (hazard ratio=1.98, 95% confidence interval: 1.19-3.28). CONCLUSIONS: Our results suggest that parental history of diabetes mellitus is associated with the incidence of T2DM in offspring differently according to the sex of the affected parent and the offspring's body weight.

BACKGROUND: Although the association between cigarette smoking and risk of type 2 diabetes is well established, its mechanisms are yet to be clarified. This study examined the possible mediating effects of adiponectin, leptin, and C-reactive protein (CRP) concentrations on the smoking-diabetes association. METHODS: Between 2002 and 2011, we followed 3338 Japanese workers, aged 35-66 years, who were enrolled in the second Aichi workers' cohort study. We used multivariable-adjusted Cox regression models to determine the hazard ratios and respective 95% confidence intervals (CIs) of the association between smoking status and risk of diabetes. A multiple mediation model with bootstrapping was used to estimate the magnitude and the respective bias-corrected (BC) 95% CIs of the indirect effects of smoking on diabetes through the three biomarkers. RESULTS: Relative to never smokers, the risk of diabetes was significantly elevated in current (hazard ratio 1.75, 95% CI 1.25-2.46) and ex-smokers (hazard ratio 1.54, 95% CI 1.07-2.22). The indirect effects of smoking on diabetes through adiponectin levels were statistically significant among light (point estimate 0.033, BC 95% CI 0.005-0.082), moderate (point estimate 0.044, BC 95% CI 0.010-0.094), and heavy smokers (point estimate 0.054, BC 95% CI 0.013-0.113). In contrast, neither the indirect effects of smoking on diabetes through leptin nor CRP levels were significant, as the corresponding BC 95% CIs included zero. CONCLUSIONS: In our analysis, adiponectin concentration appeared to partially mediate the effect of smoking on diabetes, while leptin and CRP levels did not.

BACKGROUND: Skipping breakfast has been suspected as a risk factor for type 2 diabetes (T2DM), but the associations are not entirely consistent across ethnicities or sexes, and the issue has not been adequately addressed in the Japanese population. METHODS: We followed 4631 participants (3600 men and 1031 women) in a work-site cohort of participants aged 35-66 years in 2002 through 2011 for T2DM development. Frequency of eating breakfast was self-reported and was subsequently dichotomized to breakfast skippers, who eat breakfast 3-5 times/week or less, and to eaters. Cox proportional hazards models were used to adjust for potential confounding factors, including dietary factors, smoking and other lifestyles, body mass index (BMI), and fasting blood glucose (FBG) at baseline. RESULTS: During 8.9 years of follow-up, 285 T2DM cases (231 men and 54 women) developed. Compared to participants who reported eating breakfast every day, maximally-adjusted hazard ratios and 95% confidence intervals (CI) of those with the frequency of almost every day and 3-5, 1-2, and 0 days/week were: 1.06 (95% CI, 0.73-1.53), 2.07 (95% CI, 1.20-3.56), 1.37 (95% CI, 0.82-2.29), and 2.12 (95% CI, 1.19-3.76), respectively. In a dichotomized analysis, breakfast skipping was positively associated with T2DM incidence (maximally-adjusted hazard ratio 1.73; 95% CI, 1.24-2.42). The positive associations were found in both men and women, current and non-current smokers, normal weight and overweight (BMI ≥ 25 kg/m(2)), and normal glycemic status and impaired fasting glycemic status (FBG 110 to <126 mg/dL) individuals at baseline (Ps for interaction all >0.05). CONCLUSIONS: The present study in middle-aged Japanese men and women suggests that skipping breakfast may increase the risk of T2DM independent of lifestyles and baseline levels of BMI and FBG.
