Associations between lifestyle factors, physiological conditions, and epigenetic age acceleration in an Asian population

Epigenetic clocks use DNA methylation (DNAm) levels to predict an individual’s biological age. However, relationships between lifestyle/biomarkers and epigenetic age acceleration (EAA) in Asian populations remain unknown. We here explored associations between lifestyle factors, physiological conditions, and epigenetic markers, including HannumEAA, IEAA, PhenoEAA, GrimEAA, DunedinPACE, DNAm-based smoking pack-years (DNAmPACKYRS), and DNAm plasminogen activator inhibitor 1 level (DNAmPAI1). A total of 2474 Taiwan Biobank (TWB) individuals aged between 30 and 70 provided physical health examinations, lifestyle questionnaire surveys, and blood and urine samples. Partial correlation analysis (while adjusting for chronological age, smoking, and drinking status) demonstrated that 29 factors were significantly correlated with at least one epigenetic marker (Pearson’s correlation coefficient |r|> 0.15). Subsequently, by exploring the model with the smallest Akaike information criterion (AIC), we identified the best model for each epigenetic marker. As a DNAm-based marker demonstrated to predict healthspan and lifespan with greater accuracy, GrimEAA was also found to be better explained by lifestyle factors and physiological conditions. Totally 15 factors explained 44.7% variability in GrimEAA, including sex, body mass index (BMI), waist-hip ratio (WHR), smoking, hemoglobin A1c (HbA1c), high-density lipoprotein cholesterol (HDL-C), creatinine, uric acid, gamma-glutamyl transferase (GGT), hemoglobin, and five cell-type proportions. In summary, smoking, elevated HbA1c, BMI, WHR, GGT, and uric acid were associated with more than one kind of EAA. At the same time, higher HDL-C and hemoglobin were related to epigenetic age deceleration (EAD). These findings offer valuable insights into biological aging.

Use of oral health services among pregnant women and associations with gestational diabetes and hypertensive disorders of pregnancy: Insights from the 2016-2020 Pregnancy Risk Assessment Monitoring System.

The authors examined whether use of preventive oral health care services or visits to a dentist or dental clinic for problems during pregnancy is associated with gestational diabetes and hypertensive disorders of pregnancy. Data from the 2016-2020 Pregnancy Risk Assessment Monitoring System, comprising 206,080 unweighted responses, were analyzed using descriptive statistics and multivariable logistic regression. The regression estimates were adjusted for sociodemographic and lifestyle characteristics, health history, geography, and survey year. Women who received a diagnosis of gestational diabetes (7.0%) or hypertensive disorders of pregnancy (13.3%) had lower rates of preventive oral health care and visits to a dentist or dental clinic for problems during pregnancy than those who did not have these health outcomes. Women who did not receive preventive oral health care had 1.13-fold greater odds (95% CI, 1.06 to 1.20) of having gestational diabetes and 1.08-fold greater odds (95% CI, 1.03 to 1.13) of having hypertensive disorders of pregnancy than those who did. Lack of needed visits to a dentist or dental clinic during pregnancy was associated with 1.28-fold greater odds (95% CI, 1.13 to 1.44) of having hypertensive disorders of pregnancy than in women without dental problems. Using oral health care preventive services and visits to a dentist or dental clinic for problems during pregnancy was associated with decreased odds of having gestational diabetes and hypertensive disorders of pregnancy. Health care professionals should emphasize the importance of obtaining oral health care services to promote oral and overall health among pregnant women. Dentists need to improve their knowledge and willingness to treat pregnant women, especially those with pregnancy complications.

The impact of lifestyle on environmental factors: An empirical analysis of French citizens’ behaviour towards environment

Several studies have been developed to show the importance of household carbon emissions and further investigate their sources and driving factors. These studies have paid attention to the impact of household behaviour with regard to energy use and introduced the concept of lifestyle into the study of personal carbon emissions including income, household size, and household structure. Despite the abundance of studies in the literature, it is quite surprising to note the scarcity of studies in France that address the impact of lifestyle on the environment and climate change. We use a nationwide dataset that provides a high-quality nationwide comprehensive survey of French lifestyle and their behaviour towards the environment. The results of this paper highlight the important and significant impact of the lifestyle of French citizens on transport, energy use, consumption, food waste, and clothing. Moreover, they allow assessing the impact of lifestyle on environmental factors in order to manage the harmful effect of climate change on French citizens. Therefore, this study provides decision-makers with extensive valuable information for promoting environmentally sustainable lifestyles and consumption.

The Relationship Between Sports Club Participation, Physical Activity, and Health Behaviors Among Older Korean Adults.

Participation in physical activity can improve the physical, mental, and social health of older adults, with greater benefits observed when they join sports clubs or groups rather than exercising alone. Despite the numerous advantages of older adults' participation in sports clubs, research on this topic remains scarce. This study investigated the association between participation in sports clubs and weekly physical activity, perceived health status, and health behaviors (adequate rest and sleep and regular meals and nutritional supplementation) among Korean older adults. Data on 5146 individuals aged 60 years or older, collected from the 2022-2023 Korea National Lifestyle and Sports Survey, were analyzed using frequency, chi-square, and multivariate logistic regression analyses. Significant differences were found in sex, age, weekly physical activity, perceived health status, adequate rest and sleep, regular meals and nutritional supplementation, use of exercise prescription and consultation services, participation in lifestyle physical education classes, and cessation of drinking and smoking based on participation in sports clubs. Sports club participation increased the frequency of weekly physical activity and improved perceptions of health status in older adults. The average odds ratios (ORs) for weekly physical activity were 6.667 (95% confidence interval CI = 4.316-10.297; p < 0.001), 5.237 (95% CI = 3.372-8.133; p < 0.001), and 3.042 (95% CI = 1.864-4.966; p < 0.001) for 1-2, 3-4, and 5 or more days of participation, respectively. The average ORs were 0.559 (95% CI = 0.264-1.183; p = 0.128) for inadequate rest and sleep, and 1.272 (95% CI = 0.555-1.694; p = 0.100) for adequate rest and sleep. Average ORs were 0.976 (95% CI = 0.497-1.915; p = 0.943) for irregular meals and nutritional supplementation, and 1.028 (95% CI 0.770-1.373; p = 0.851) for regular meals and nutritional supplementation. However, sports club participation was not significantly associated with sufficient rest and sleep or regular meals and nutritional supplementation. Older adults need support to join sports clubs, which can promote their physical activity and health.

Metabolic syndrome and spatial disparities: The role of socioeconomic deprivation and medical resource availability in the Cijin district, Taiwan.

Metabolic syndrome (MetS) is a global health concern with spatial disparities, especially in disadvantaged neighborhoods. This study aimed to examine the association between area-level socioeconomic deprivation, the availability of medical resources in disadvantaged areas such as the Cijin district, and the prevalence of MetS in Taiwan. We used two representative secondary cross-sectional datasets, including physical examinations and lifestyle surveys from 2016 to 2020, sourced from the Taiwan Biobank and the Cijin District Adult Lifestyle and Health Survey. Our findings indicate that residing in the Cijin district, characterized by socioeconomic deprivation and limited medical resources, is associated with significantly higher odds of MetS (aOR = 1.45, 95% CI = 1.28-1.64, p <0.001). Additionally, living in areas with medium (aOR = 1.12, 95% CI = 1.07-1.17, p <0.001) and high area-level socioeconomic deprivation indexes (aOR = 1.13, 95% CI = 1.01-1.25, p <0.001) is linked to a higher likelihood of MetS. Conversely, residing in high medical resource availability index areas is associated with a lower risk of MetS (aOR = 0.92, 95% CI = 0.86-0.99, p = 0.026). We found a link between socioeconomic deprivation and limited medical resources, especially in disadvantaged areas such as the Cijin district, contributing to a higher MetS risk. Residents in these areas often struggle to access healthcare and preventive care. Addressing these disparities requires comprehensive public health initiatives and targeted policy interventions to improve residents' well-being.

Sexual experiences and behaviours of the parents in the Avon Longitudinal Study of Parents and Childhood (ALSPAC)

The aim of this data note is to describe the sexual experiences, functioning and behaviour data collected from the parent cohorts of the Avon Longitudinal Study of Parents and Children (ALSPAC) occurring during their childhoods and up to 19 years after the birth of the index child. ALSPAC is an ongoing birth cohort which enrolled 14,541 pregnant women living in Avon, an area of southwest England, with expected dates of delivery between April 1991 and December 1992 inclusive. It continues collecting data on these mothers (age range at delivery &lt;16–41 years), their partners (age range at delivery &lt;16–65), and their offspring, so far resulting in 100,000+ phenotype variables. During the index pregnancy the mothers were asked (and at 8 months post-delivery for partners) about their early sexual experiences to identify sexual abuse, the age at which an event first occurred, along with the type of perpetrator (e.g. stranger, relatives, boy/girlfriend). There are also data on these parents’ experiences of sexual assault as adults. Both parents were asked also about sexual abuse within a battery of questions identifying Adverse Childhood Events (ACEs). Further longitudinal data described here includes satisfaction with sexual and non-sexual sides of their relationship; sexual functioning; and at seven years post-delivery, both parents were asked to describe their sexual orientation as well as the sex of their partners. These data provide the ability to compare generational differences between parental sexual experiences and behaviours with those of their offspring, as well as allowing comparisons with other longitudinal surveys where similar (or identical) information has been collected such as the National Survey of Sexual Attitudes and Lifestyles (NATSAL-3). This paper forms a companion to a further data note describing similar data collected on the offspring cohort.

Association between adolescent lifestyle factors and high-energy traumas in early adulthood: A longitudinal study

IntroductionLongitudinal studies investigating lifestyle factors as risk factors for high-energy traumas from adolescence to adulthood are lacking. The aim of this study was to investigate the influence of 14 to 18-year old adolescent health-related behaviours, overweight, chronic disease, family socioeconomic status (SES), and adulthood education level on the risk of high-energy traumas during the average 27-year follow-up in Finland. Materials and methodsThe baseline data were surveys gathered biennially from 1981 to 1997 (the Adolescent Health and Lifestyle Survey) and individually linked with outcome data on high-energy traumas retrieved from the Care Register for Health Care until the year 2018. A logistic regression model was used to analyse the associations between the exposure variables in adolescence (frequent physical activity, overweight, smoking, monthly drunkenness, chronic disease, family SES, adulthood education level) and the overall risk for high-energy traumas. Adjusted odds ratios (aOR) with 95 % confidence intervals (CIs) were computed. ResultsA total of 876 persons (1.8 %) had a high-energy trauma during the follow-up. High-energy trauma diagnoses overall were more common among males than among females (2.8 % vs 1.0 %). Follow-up showed that those who smoked (aOR 1.49, CI 1.40–1.58), were drunk monthly (aOR 1.49, CI 1.39–1.59), had a chronic disease (aOR 1.22, CI 1.12–1.34) in adolescence or had attained only low education level in adulthood (aOR 1.39, CI 1.30–1.48) had higher odds for high-energy traumas. Frequent physical activity or overweight in adolescence were not related to the higher odds for high-energy traumas. ConclusionSmoking, monthly drunkenness, self-reported chronic diseases in adolescence, and low educational level in adulthood increased the risk of high-energy traumas during the mean follow-up of 27-years. Frequent physical activity and overweight in adolescence did not predict the occurrence of high-energy traumas. Intervention programs should also focus on the long-term consequences of these risk factors.

The gendered division of household labor and decision-making in Tehran, Iran

The division of labor and decision-making within households is highly influenced by gender norms and resource allocation. However, there has been a marked shift away from traditional gender roles in domestic tasks and decision-making in recent years. This study examines the division of domestic responsibilities, childcare, and decision-making within households, as well as the socioeconomic factors that influence these dimensions in Iran. Data come from the &amp;ldquo;Survey of Married Lifestyle,&amp;rdquo; which included 1736 married people aged 18 years and over in Tehran, selected through a multi-stage random sampling process. The results reveal that while women are increasingly involved in decision-making, they still primarily shoulder the burden of household chores and childcare. Factors such as women&amp;rsquo;s education and income, as well as men&amp;rsquo;s education and dual-earner status, are key determinants of the division of labor in households. Social policies that focus on enhancing women&amp;rsquo;s access to education and economic opportunities are crucial for promoting gender equality and empowering women in household decision-making.

Secular trends in blood pressure among university students in Japan over the last two decades.

High blood pressure (BP) increases the risk of cardiovascular disease, not only among middle-aged and older adults, but also in young adults. Early interventions for high BP may prevent future organ damage. Therefore, it is essential to monitor BP trends in young adults to support this approach. During the COVID-19 pandemic, a trend of increasing BP was observed worldwide. However, young adults have not been fully evaluated. Therefore, this study examined BP trends among university students (n = 106,691) over two decades, every 5 years from 2003 to 2023, including the period before and after the COVID-19 pandemic. From 2003 to 2018, there were no notable changes in BP. However, following the COVID-19 pandemic, increased BP was observed in both men and women, with systolic BP increasing from 118.1 (SD, 14.2) mmHg in 2018 to 120.6 (SD, 12.5) mmHg in 2023 among men, and from 104.6 (SD, 11.8) mmHg to 105.1 (SD, 11.7) mmHg among women. These trends were particularly pronounced among students with normal and underweight somatotypes and among first- and second-year students. The results of the lifestyle survey showed a decrease in smoking and drinking habits, insufficient sleep, mental stress, consumption of fast food and snacks, and an increase in exercise habits. Although contributing factors to the recent increase in BP were not identified, there was an upward trend in BP among Japanese university students. It is important to carefully observe how BP trends change over the long term following the end of the COVID-19 pandemic.

Factors influencing smoking cessation: Insights from Singapore's nationwide health and lifestyle survey.

Singapore has implemented an evidence-based smoking cessation framework to support smokers in quitting. Our study investigated the prevalence and correlates of (1) quit attempts (QA) and quit intentions (QI) among current smokers, and (2) smoking cessation (SC) among ever-smokers in Singapore. Data was collected from a nationwide survey conducted between 2020 and 2022. QA was defined as attempting to stop smoking at least once in the past 12 months, while QI was defined as planning to quit smoking within the next 30 days or the next 6 months. SC referred to individuals who quit smoking over 6 months ago. Sociodemographic factors, doctor's advice to quit and perceived harm from smoking were assessed using logistic regression among current smokers (n=1024) and ever-smokers (n=1457). Among current smokers, 31.3% and 41.2% reported QI and QA, respectively. Smokers with secondary or pre-tertiary education were less likely to report QI compared to those with a degree or higher. Doctor's advice to quit was associated with a higher likelihood of QA. Among ever-smokers, 25.3% reported SC, and this was more likely when they perceived smoking 1 or more packs of cigarettes daily as posing a moderate or high health risk. Educational campaigns should focus on simplifying messages for individuals with lower literacy levels. Smoking cessation training can be incorporated into medical education, and graphic health warnings on cigarette packs can help effectively communicate the dangers of smoking.

Psychopathology and the Validity of Gastrointestinal Symptom Reporting as Revealed Through Cluster Analyses of MMPI-2-RF Results

BackgroundPsychological state, self-reported gut symptoms, and somatic complaints are recognized relationships that can impact health assessment and subsequent treatment.AimTo investigate the impact of psychological state and personality on symptom self-reporting and somatization.MethodsSixty-two (62) participants from the Hunter region of NSW (Australia) undertook a survey of health and lifestyle along with an MMPI-2-RF assessment of personality, psychopathology, and test-taking attitude. Participants also completed the Rome Criteria to assess functional gastrointestinal disorders (FGIDs). To assist the interpretation of MMPI-2-RF results, clustering was applied to identify similar responses and sub-cohort profiles of reporting.ResultsCluster analysis revealed four sub-cohorts, stratified by psychopathology, gut-related symptoms, and the validity of self-reported somatic complaints. Sample clustering identified one sub-cohort defined by high rates of negative affectivity and suicidal ideation. Apart from these differences, clusters were uniform for age, sex, smoking, mental health diagnoses, as well as for gut-related conditions.ConclusionResults provide further evidence of the interaction of the gut–brain axis and its relationship to serious mental health conditions. It also points to the need to assess the veracity of self-reported symptomatology that may be both pathognomonic for psychopathology but might also be a consequence of gut dysbiosis. Clustering assisted these investigations by defining distinct sub-cohorts based on participant MMPI-2-RF responses.

ImplicationsThe partnership between CanPath and HDRN Canada has significant implications for advancing population health research in Canada. By providing researchers with access to linked data from diverse sources, the partnership enables comprehensive investigations into health determinants, disease patterns, and clinical outcomes. This enhances the scope and depth of population health research in Canada, thereby leading to a better understanding of the most pressing health challenges.

The Influence of Adolescent health-related Behaviors on Degenerative Low Back Pain Hospitalizations and Surgeries in Adulthood: A Longitudinal Study.

Retrospective longitudinal study. This study aims to investigate the influence of adolescent health-related behaviors (physical activity, high BMI, drunkenness, smoking), self-reported chronic disease, and low socioeconomic status (SES) on the development of low back pain requiring hospitalization or surgery. The baseline data were surveys gathered biennially in 1981-1997 (the Adolescent Health and Lifestyle Survey) and individually linked with outcome data, degenerative low back pain hospitalizations, and spine surgeries retrieved from the Care Register for Health Care. A total of 47 724 participants were included. Explanatory variables included physical activity, high BMI, smoking, monthly drunkenness, chronic diseases, and family SES. A logistic regression model was used to analyze the influence of adolescent health-related behaviors (physical activity, high BMI, drunkenness, smoking), self-reported chronic disease, and low socioeconomic status (SES) on degenerative low back pain hospitalization, lumbar disc herniation (LDH) hospitalization and/or spine surgery. Covariates were selected using directed acyclic graphs (DAGs). A total of 5538 participants had degenerative low back pain hospitalizations, 2104 had LDH hospitalizations, and 913 had spinal surgery over an average of 27-years follow-up. High BMI (aOR 1.25, CI 1.12-1.38), smoking (aOR 1.53, CI 1.43-1.62), monthly drunkenness (aOR 1.17, CI 1.10-1.26), and chronic diseases (aOR 1.47, CI 1.35-1.61) in adolescence increased the odds of hospitalizations during follow-up. In addition, high BMI (aOR 1.37, CI 1.09-1.72), smoking (aOR 1.40, CI 1.21-1.61), and monthly drunkenness (aOR 1.19, CI 1.01-1.39) increased the odds of spine surgeries. We found that smoking, high BMI, monthly drunkenness, chronic diseases, and low family SES in adolescence increased the likelihood of degenerative low back pain hospitalizations in adulthood. In addition, high BMI, smoking, and monthly drunkenness in adolescence increased the odds of spinal surgeries.

Lifestyle, Cognitive, and Psychological Factors Associated With a Resilience Phenotype in Aging: A Multidimensional Approach on a Population-Based Sample of Oldest-Old (80+).

To investigate the determinants of resilience phenotype in aging, operationalized as the maintenance of cognitive, physical, and psychological health in very old individuals (80+), we investigated the structure and interrelated impact of the main resilience-enhancing factors, which are usually studied in separate research fields. Participants were older adults without dementia recruited for the fifth wave of the InveCe.Ab population-based cohort study (aged 83-87 years). Multidimensional evaluation comprised blood sampling, social and lifestyle survey, and geriatric and neuropsychological assessment. We classified resilient individuals as displaying normal cognition, functional independence, and mental health. First, we performed exploratory factor analysis (EFA) to examine the underlying structure of the relevant cognitive, lifestyle, physical, and psychological resilience-enhancing factors. The factors obtained were included as predictors of the resilience phenotype in the logistic regression model, controlling for sociodemographic and cumulative exposure to physical and psychosocial stressors, including COVID-19 infection. Among the 404 enrolled participants, 153 (38%) exhibited the resilience phenotype. EFA resulted in the identification of six factors (59% of variance): cognitive reserve, affective reserve, insecure attachment, current lifestyle, physical reserve, and avoidant attachment. Among these factors, cognitive reserve, affective reserve, and current lifestyle significantly and independently predicted resilience status, controlling for cumulative exposure to age-related stressors and COVID-19 infection. Our findings showed that, even in very old age, both early and late life modifiable factors affect individuals' ability to adapt to the aging process, thus confirming the importance of a life-course approach to improve health outcomes in the aged population.

The Effects of Medical Students’ Traits and College Life on Academic Failure Mediated by Mental Health

This study utilized cohort data, student lifestyle surveys, and mental health examination results from a medical school to investigate the impact of factors such as hometown, alcohol use, smoking, university life adaptation, and aptitude on academic failure, with mental health serving as a mediator. We analyzed data from 409 of the 549 incoming students at Keimyung University School of Medicine, excluding 140 individuals with missing data, from the academic years 2015 to 2021. Significant differences were found according to hometown in feelings of depression, suicidal tendencies, and internet addiction. There were also significant differences based on university life adaptation in feelings of depression, suicidal tendencies, and internet addiction, as well as significant differences according to academic aptitude in feelings of depression and internet addiction. Academic failure showed significant differences based on hometown, university life adaptation, and academic aptitude. Furthermore, students’ hometown had a complete mediating effect on academic failure together with feelings of depression, suicidal tendencies, and internet addiction. University life adaptation exhibited a complete mediating effect with suicidal tendencies and a partial mediating effect with feelings of depression and internet addiction. Academic aptitude demonstrated partial mediating effects on feelings of depression, suicidal tendencies, and internet addiction. Based on these results, we suggest establishing counseling programs tailored to the characteristics of medical students, and various programs for university life adaptation are necessary. There is also a need for diverse programs not only for clinical training, but also for different career paths.

Problematic smartphone use and mental health outcomes among Singapore residents: The health and lifestyle survey

BackgroundThe excessive use of smartphones and its association with adverse outcomes has been widely reported, with several studies showing an association between smartphone overuse, depression, anxiety, and sleep-related problems. MethodsThe study used data from the Health and Lifestyle Survey, a nationwide population survey. It examined the prevalence of Problematic Smartphone Use (PSU) and its association with mental health outcomes among Singapore residents aged 15–65 years. ParticipantsParticipants were assessed for PSU using the Smartphone Addiction Scale-Short Version, psychological distress with the Patient Health Questionnaire-9, and Generalised Anxiety Disorder −7 questionnaire, sleep problems using the Insomnia Severity Index, and positive mental health with Rapid Positive Mental Health Instrument. ResultsIn all, 6509 participants completed the survey, giving a survey response rate of 73.2 %. The prevalence of PSU was 30.2 % in the population. Individuals with PSU were more likely to have symptoms of moderate or severe depression (OR: 3.2, 95 % CI: 2.4–4.4), anxiety (OR: 3.4, 95 % CI: 2.4–4.8), insomnia (OR: 3.4, 95 % CI: 2.8–4.2), and poorer positive mental health (β: −0.3, 95 % CI: −0.4 to −0.2). ConclusionsThe study is the first to examine PSU in a national sample of Singaporeans across a wide age range. It provides valuable insights into mental health comorbidities among those with PSU, which is useful for practitioners.

Sexual experiences, behaviours and attitudes in the parents in the Avon Longitudinal Study of Parents and Childhood (ALSPAC)

The aim of this data note is to describe the sexual experiences, behaviours, and attitudes data collected from the parent cohorts of the Avon Longitudinal Study of Parents and Children (ALSPAC) over a 30-year period. ALSPAC is an ongoing birth cohort which enrolled 14,541 pregnant women living in Avon, a county of southwest England, with expected dates of delivery between April 1991 and December 1992 inclusive and continues collecting data on these mothers (age range at delivery &lt;16–41 years), their partners (age range at delivery &lt;16–65), and their offspring, so far resulting in 100,000+ phenotype variables. During the index pregnancy the mothers were asked (and at 8 months post-delivery for partners) about their early sexual experiences to identify sexual abuse/assaults and the age at which an event first happened. Both parents were asked also about sexual abuse within a battery of questions identifying Adverse Childhood Events (ACE). Further longitudinal data described here includes satisfaction with sexual and non-sexual sides of their relationship; sexual functioning; and at seven years post-delivery, both parents were asked to describe their sexual orientation as well as the sex of their partners and cohabiting partners. These data provide the ability to compare generational differences between parental sexual behaviours and attitudes with those of their offspring, as well as allowing comparisons with other longitudinal surveys where similar (or identical) information has been collected such as the National Survey of Sexual Attitudes and Lifestyles (NATSAL-3). This paper forms a companion to another data note describing similar data collected on the offspring cohort.

Prevalence of consumption of illicit drugs and associated factors from a nationwide epidemiological survey: The Singapore Health and Lifestyle Survey.

The primary aims of the current nationwide study were to establish the lifetime and 12-month prevalence of consumption of illicit drugs and its correlates in the general population of Singapore. A representative sample of 6509 Singapore residents (Singapore citizens and permanent residents) aged between 15 and 65 years were randomly selected for participation. Questionnaires were administered to assess the consumption of illicit drugs and collect information on correlates. All analyses were weighted to produce prevalence estimates for the consumption of drugs and other measured outcomes. Rao-Scott chi-square test and logistic regression analyses were performed to determine the association of sociodemographic and clinical characteristics with lifetime consumption of illicit drugs. The study was completed with a response rate of 73.2%. The lifetime prevalence of consuming illegal drugs was 2.3% (95% confidence interval [CI] 1.9-2.8) (n=180). Compared to individuals aged 15-34, those aged 50-65 (odds ratio [OR] 0.3, 95% CI 0.2-0.7) had lower odds of lifetime drug consumption. Current smokers (OR 4.7, 95% CI 2.7-8.3) and ex-smokers (OR 5.9, 95% CI 3.2-11.1) had significantly higher odds of lifetime drug consumption than non-smokers. Individuals with hazardous alcohol use (OR 3.3, 95% CI 1.7-6.5) had higher odds of lifetime drug consumption than those without hazardous alcohol use. This is the first nationwide study to examine the prevalence of illicit drug consumption in the general population of Singapore. The results highlight the need to increase awareness of drug consumption in Singapore, especially among parents, teachers, healthcare workers and others who work with young people.

Trajectories of liver dysfunction and long-term evacuation status after the great East Japan earthquake: The Fukushima Health Management Survey

ObjectivesIn the Fukushima Health Management Survey (FHMS), the association between subsequent evacuation status, such as return and continued evacuation, and trends in liver dysfunction remains unclear. Therefore, this study evaluated this association using FHMS data through fiscal year (FY) 2018. MethodsThe 34,435 (14,063 men and 20,372 women) study participants underwent a Comprehensive Health Check, answered the Mental Health and Lifestyle Survey questionnaire in FY 2011, and were followed up until FY 2018. The participants were classified by trajectory for liver dysfunction using group-based trajectory modeling, and we examined differences in study items as of FY 2012 by each trajectory. Additionally, we divided the 13 municipalities, including evacuation zones, into partially evacuated, returnable, and difficult-to-return areas according to the lifting of evacuation orders as of FY 2018, and logistic regression modeling was used to investigate the association between long-term post-disaster evacuation status and the liver dysfunction trajectory. ResultsParticipants were classified by group-based trajectory modeling into Group 1 (continuously low prevalence rate; 62.2 %), Group 2 (improvement from high prevalence in FY2011; 10.8 %), Group 3 (like group 1 prevalence in FY2011 but increasing afterwards; 11.2 %), and Group 4 (continuously high prevalence; 15.8 %), respectively. Multivariate logistic regression modeling revealed the difficult-to-return areas and returnable areas had a higher risk of being in the Group 2, Group 3, and Group 4, compared with the partially evacuated areas. ConclusionsOur findings suggest that liver dysfunction is more likely to persist in areas where evacuation was more prolonged.
