Once in NEET, always in NEET? Childhood and adolescent risk factors for different NEET patterns.

Young adults in Neither in Employment, Education nor Training (NEET) are at risk of adverse labour market outcomes. Earlier studies often measured NEET status at one time point or compared persistent NEETs with non-NEETs, neglecting other patterns of NEET status. Evidence on early life factors associated with NEET patterns is lacking. This study aims to (i) identify patterns of NEET status over time and (ii) examine whether factors in childhood and adolescence are associated with these patterns. Data were used from 1499 participants of the TRacking Adolescents' Individual Lives Survey (TRAILS), a Dutch prospective cohort study with 15-year follow-up. NEET status was assessed at ages 19, 22 and 26. Socioeconomic status of parents (SES), intelligence and negative life events were measured at age 11, educational attainment at age 26 and mental health problems at ages 11, 13.5 and 16. Data were analyzed using multinomial logistic regression analysis. Four NEET patterns were identified: (i) non-NEETs (85.2%), (ii) early NEETs (4.5%), (iii) late NEETs (5.7%) and (iv) persistent NEETs (4.5%). Reporting internalizing problems at age 11 was a risk factor for early and late NEETs [odds ratio (OR) 2.77, 95% confidence interval (CI) 1.16-6.62; OR 5.00, 95% CI 2.22-11.3, respectively]. Low parental SES, lower intelligence scores and negative life events (≥3) were risk factors for persistent NEETs (OR 4.45, 95% CI 2.00-9.91; OR 0.96, 95% CI 0.94-0.98; OR 4.42, 95% CI 1.62-12.08, respectively). The results highlight the importance of timing and duration of NEET status and emphasize the need for tailored interventions to prevent specific NEET patterns.

Association of Traditional dietary pattern with early and precocious puberty: a population-based cross-sectional study.

Precocious puberty is an endocrine disease that is diagnosed by sex, age, and Tanner stage of puberty. This study aimed to investigate the association between various dietary patterns and early or precocious puberty, especially Traditional dietary patterns, which have been rarely investigated. A total of 4085 primary school students in grades 1-3 (6-9 years) completed individual characteristic surveys, health examinations, and food frequency questionnaires (FFQs). Physical examinations were also conducted to assess obesity and pubertal onset. Traditional, Westernized, and Protein dietary patterns were determined by factor analysis, and their associations with pubertal onset were analyzed by multiple logistic regression analysis. Compared to the other two patterns, children who predominant the Traditional dietary pattern were protectively associated with precocious puberty (OR = 0.72, 95% CI = 0.55, 0.94), even after adjusting the confounders (OR = 0.66, 95% CI = 0.48, 0.89). Neither the Westernized nor Protein dietary pattern demonstrated an association with pubertal onset. The Traditional dietary pattern was negatively associated with children's weight status, classified by body mass index (BMI), and was positively associated with parental education. The maternal education and the Protein dietary pattern were negatively related. Traditional dietary patterns were protective associated with early and precocious puberty among Chinese children. The Traditional dietary pattern was protective associated with early puberty or precocious puberty in children, as found in large-scale population-based public health research. Current research primarily focuses on Westernized dietary patterns, and we studied Traditional dietary patterns to further explore the influence of food on children's puberty development. We discovered that children's preference for Traditional dietary patterns is protective of pubertal development, which implies that society and parents can benefit from diet guidance to protect children's natural development during adolescence.

ReSurveyEurope: A database of resurveyed vegetation plots in Europe

AbstractAimsWe introduce ReSurveyEurope — a new data source of resurveyed vegetation plots in Europe, compiled by a collaborative network of vegetation scientists. We describe the scope of this initiative, provide an overview of currently available data, governance, data contribution rules, and accessibility. In addition, we outline further steps, including potential research questions.ResultsReSurveyEurope includes resurveyed vegetation plots from all habitats. Version 1.0 of ReSurveyEurope contains 283,135 observations (i.e., individual surveys of each plot) from 79,190 plots sampled in 449 independent resurvey projects. Of these, 62,139 (78%) are permanent plots, that is, marked in situ, or located with GPS, which allow for high spatial accuracy in resurvey. The remaining 17,051 (22%) plots are from studies in which plots from the initial survey could not be exactly relocated. Four data sets, which together account for 28,470 (36%) plots, provide only presence/absence information on plant species, while the remaining 50,720 (64%) plots contain abundance information (e.g., percentage cover or cover–abundance classes such as variants of the Braun‐Blanquet scale). The oldest plots were sampled in 1911 in the Swiss Alps, while most plots were sampled between 1950 and 2020.ConclusionsReSurveyEurope is a new resource to address a wide range of research questions on fine‐scale changes in European vegetation. The initiative is devoted to an inclusive and transparent governance and data usage approach, based on slightly adapted rules of the well‐established European Vegetation Archive (EVA). ReSurveyEurope data are ready for use, and proposals for analyses of the data set can be submitted at any time to the coordinators. Still, further data contributions are highly welcome.

Dynamic Associations Between Anxiety Symptoms and Drinking Behavior From Early Adolescence to Young Adulthood

PurposeResearch is inconclusive with respect to the possible risk-increasing effect of anxiety symptoms on heavy drinking behavior among adolescents and young adults. Adult role transitions and changes in the social context from early adolescence into young adulthood may impact the association between anxiety symptoms and alcohol use. MethodsThe TRacking Adolescents’ Individual Lives Survey, including 2,229 individuals at baseline, was used to evaluate the bi-directional and longitudinal associations between anxiety symptoms and alcohol use, using data at 14, 16, 19, 22, and 25 years of age. ResultsCross-lagged models revealed a relatively stable negative association at 14, 16, and 19 years, showing that relatively higher anxiety symptoms were associated with relatively lower drinking levels three years later. This effect was absent in young adulthood. There was no evidence for significant associations between alcohol use and subsequent anxiety symptoms, with the exception of alcohol use at age 19, which predicted relatively lower levels of anxiety symptoms at age 22. DiscussionOverall, the results indicated that anxiety symptoms may withhold adolescents from (heavy) drinking, although this protective effect disappeared in young adulthood. Transitions in social contexts as well as autonomy and adult responsibilities could underlie the changing association between alcohol use and anxiety symptoms throughout adolescence and young adulthood.

Bayesian Multi-View Clustering given complex inter-view structure.

Multi-view datasets are becoming increasingly prevalent. These datasets consist of different modalities that provide complementary characterizations of the same underlying system. They can include heterogeneous types of information with complex relationships, varying degrees of missingness, and assorted sample sizes, as is often the case in multi-omic biological studies. Clustering multi-view data allows us to leverage different modalities to infer underlying systematic structure, but most existing approaches are limited to contexts in which entities are the same across views or have clear one-to-one relationships across data types with a common sample size. Many methods also make strong assumptions about the similarities of clusterings across views. We propose a Bayesian multi-view clustering approach (BMVC) which can handle the realities of multi-view datasets that often have complex relationships and diverse structure. BMVC incorporates known and complex many-to-many relationships between entities via a probabilistic graphical model that enables the joint inference of clusterings specific to each view, but where each view informs the others. Additionally, BMVC estimates the strength of the relationships between each pair of views, thus moderating the degree to which it imposes dependence constraints. We benchmarked BMVC on simulated data to show that it accurately estimates varying degrees of inter-view dependence when inter-view relationships are not limited to one-to-one correspondence. Next, we demonstrated its ability to capture visually interpretable inter-view structure in a public health survey of individuals and households in Puerto Rico following Hurricane Maria. Finally, we showed that BMVC clusters integrate the complex relationships between multi-omic profiles of breast cancer patient data, improving the biological homogeneity of clusters and elucidating hypotheses for functional biological mechanisms. We found that BMVC leverages complex inter-view structure to produce higher quality clusters than those generated by standard approaches. We also showed that BMVC is a valuable tool for real-world discovery and hypothesis generation.

Development of Gender Non-Contentedness During Adolescence and Early Adulthood

Adolescence is an important period for the development of gender identity. We studied the development of gender non-contentedness, i.e., unhappiness with being the gender aligned with one’s sex, from early adolescence to young adulthood, and its association with self-concept, behavioral and emotional problems, and adult sexual orientation. Participants were 2772 adolescents (53% male) from the Tracking Adolescents’ Individual Lives Survey population and clinical cohort. Data from six waves were included (ages 11–26). Gender non-contentedness was assessed with the item “I wish to be of the opposite sex” from the Youth and Adult Self-Report at all six waves. Behavioral and emotional problems were measured by total scores of these scales at all six waves. Self-concept was assessed at age 11 using the Global Self-Worth and Physical Appearance subscales of the Self-Perception Profile for Children. Sexual orientation was assessed at age 22 by self-report. In early adolescence, 11% of participants reported gender non-contentedness. The prevalence decreased with age and was 4% at the last follow-up (around age 26). Three developmental trajectories of gender non-contentedness were identified: no gender non-contentedness (78%), decreasing gender non-contentedness (19%), and increasing gender non-contentedness (2%). Individuals with an increasing gender non-contentedness more often were female and both an increasing and decreasing trajectory were associated with a lower global self-worth, more behavioral and emotional problems, and a non-heterosexual sexual orientation. Gender non-contentedness, while being relatively common during early adolescence, in general decreases with age and appears to be associated with a poorer self-concept and mental health throughout development.

Pharmacokinetic Interaction of Kratom and Cannabidiol in Male Rats.

Kratom and cannabidiol products are used to self-treat a variety of conditions, including anxiety and pain, and to elevate mood. Research into the individual pharmacokinetic properties of commercially available kratom and cannabidiol products has been performed, but there are no studies on coadministration of these products. Surveys of individuals with kratom use history indicate that cannabidiol use is one of the strongest predictors of both lifetime and past month kratom use. The purpose of this study was to determine if there are changes in pharmacokinetic properties when commercially available kratom and cannabidiol products are administered concomitantly. It was found that with concomitant administration of cannabidiol, there was a 2.8-fold increase in the exposure of the most abundant kratom alkaloid, mitragynine, and increases in the exposure of other minor alkaloids. The results of this work suggest that with cannabidiol coadministration, the effects of kratom may be both delayed and increased due to a delay in time to reach maximum plasma concentration and higher systemic exposure of the psychoactive alkaloids found in kratom.

Assessing Workplace Violence: Methodological Considerations.

The risk of violence is present in all workplaces. It must be accurately assessed to establish prevention and protection measures tailored to the features of each situation. The risk management process requires compliance in a sequential order: 1) risk identification, 2) quantitative risk assessment, and 3) impact assessment. Gathering workers' experiences using lists, focus groups, or participatory ergonomics groups is necessary to identify the phenomenon. For risk assessment, spontaneous reporting of events is often insufficient. It may be complemented with two methods: systematic recording of violent events that occurred in the past year during periodic medical examinations of workers and targeted surveys. The epidemiological analysis of data from individual interviews and surveys provides the phenomenon's prevalence, incidence, and evolution. Moreover, reporting the harm suffered by victims of violence allows constructing impact matrices to allocate resources where they are most needed.

The Potential Usefulness of Peripheral Somatosensory Stimulation in Improving Sleep Quality in Patients with Insomnia

Background Insomnia and other sleep disorders represent a major cause of disability and impaired productivity. We evaluated the impact of peripheral somatosensory stimulation (PSS) on sleep quality in 12 patients with varying degrees of insomnia. Methods Twelve adult patients underwent daily PSS therapy for a 4-week period and were evaluated using the Insomnia Severity Index at baseline (prior to initiation of therapy) and then at the conclusion of the treatments. All data were obtained through a self-reported 7-question survey evaluating overall severity of insomnia symptoms and the impact of sleep patterns on satisfaction with sleep, daily functioning, and overall quality of life. Changes from baseline insomnia scores were analyzed using cumulative link mixed models (CLMMs). Results Seven men and five women completed one month of PSS therapy. Mean age was 55.1 (range 29 to 80 years). No adverse events were described by the patients. The average total change from baseline score was -10.3 points (baseline: 16.5 vs. week 4: 6.2). Patients had statistically significant improvements for every individual survey question by week 4. The median composite score was improved from baseline, with an overall median score of 2 (IQR: 1.25 – 2.75, min-max: 1-4) at baseline compared to 0.5 (IQR: 0 – 0.25, min-max: 0-2) by week 4 (MD = -1 95% CI: , p < 0.001), signaling typically moderate insomnia at baseline vs. typically minimal to no symptoms by week 4. The predicted probability of obtaining the best outcome (score=0) was 9% at baseline vs. 53% by week 4. The overall cumulative odds ratio was 11.9 (p < 0.001), suggesting that on average, the odds of moving from one score to a lower (improved) score at week 4 compared to the baseline are approximately 12 times higher than moving to a neutral or worse score. Conclusions PSS stimulation appeared to have a significantly favorable effect on sleep quality in this group of patients. Symptoms related to ability to fall asleep, remain asleep, and overall quality of sleep were all improved with PSS therapy. We suggest that further investigation into the potential usefulness of PSS therapy in patients with sleep disorders is warranted.

"I Was Told to Think Like a Middle-Aged White Woman": A Survey on Identity and the Association of Social Work Boards Exam.

The release of the 2022 Association of Social Work Boards (ASWB) exam passage rate report confirmed what many test takers who failed their exam believe. The ASWB exams are biased, with differential passage rates based on the test taker's race, age, and "English as a second language" status. However, the report only offered basic descriptive statistics and lacked insight into the test takers' experience. The present study addresses this gap. Results are from a 2022 survey of individuals who had taken the ASWB master's level licensing exam (N = 1,045) highlighting test taker identity and experience. Thirty percent of the study sample identified as neurodivergent, 29.1 percent as primary caregivers, and 27.1 percent as Black, Indigenous, or persons of color. White respondents had the highest first-attempt passing rates (95.7 percent), followed by Latinx and Black respondents (84.9 percent and 78.2 percent, respectively). Forty-four respondents reported taking the test three or more times before passing. Among this group, 52 percent identified as Black, 25 percent as White, and 18 percent as Latinx. Respondents were asked how they felt their identity impacted their experience, and three interrelated themes emerged: privilege, challenges, and critique of the exam. Respondents discussed the impact of having or not having privilege; the emotional, physical, and financial challenges of preparing for the exam; and the ways in which they experienced the exam as biased.

Differences in prescribed medicinal cannabis use by cannabinoid product composition: Findings from the cannabis as medicine survey 2020 (CAMS-20) Australia-wide study.

Prescribed medicinal cannabis (MC) is an increasingly common prescription in Australia for treating pain, anxiety, and sleep disorders. Prescribed MC products generally contain tetrahydrocannabinol (THC) and/or cannabidiol (CBD) in a variety of dose levels and forms. It is unclear whether THC and CBD products are used by patients with different characteristics and for different conditions. To examine consumer experiences of using THC- and CBD-containing prescribed MC products to better understand how they are being used within the Australian context. We utilised data collected from an online anonymous cross-sectional survey of individuals (CAMS-20 survey), consisting of Australian residents using cannabis for therapeutic reasons. We focused on a subgroup of participants (N = 546) receiving prescribed MC products. We utilised linear, logistic, and multinomial regression modelling to analyse responses to survey questions based on the cannabinoid profile of the prescribed product. Participants prescribed THC-dominant MC products were statistically more likely to be younger, male, and to prefer inhaled routes of administration than participants using CBD-dominant products who were older, female, and preferred oral routes of administration. Pain and mental health were the most common reasons for all types of prescribed MC, but were more likely to be treated with THC than CBD despite the significantly higher risk of mild to severe drowsiness, dry mouth and eye irritation. Consumer reported effectiveness of prescribed MC was very positive, particularly for THC-containing products. Consumers on opioids and antipsychotics were statistically more likely to be prescribed THC-containing products than products containing CBD only, despite the greater risk of impairment. This Australia-wide study found clear differences in consumer-reported experiences of prescribed THC- and CBD-containing products. Current prescriptions of these products do not always align with relevant clinical guidance. Educating prescribers around cannabinoid products is essential to ensure optimal prescribing practices and to prevent avoidable drug side effects and interactions.

Art, photography, and museums for senior students

The present research approaches the need to bring art closer to adult students, analyzing the process and the results of a course in a university program for the public over 55 years old. The interest of these students in art is given in most cases because they would have wanted to study art in their youth. Beyond the usual focus either on art history or artistic workshops, this program generates a multidisciplinary experience, introducing concepts and practices such as urban derive or performance. Aspects such as visual culture or digital technologies and art education are also integrated. This study adopted a research methodology of mixed nature, combining case study with arts-based research. The photographs acquire an important value as a result of the research. The benefits of lifelong learning were evaluated based on the participatory practices taking into account the previous experience of students and their knowledge in this regard. The information collected through individual surveys and focus groups highlighted a positive and rewarding result, according to the students.

Capturing Swiss economic confidence

Survey data can offer timely information on the current state of the economy and its short-term outlook. In this paper, we propose a “Swiss Economic Confidence Index” (SEC). This is a monthly indicator based on aggregating a selection of individual survey indicators, which we show to have favorable leading properties. Applying simple criteria, we select those surveys from a set of currently more than 250 sentiment indicators. We show that the SEC index provides useful signals on GDP growth in a number of real-time out-of-sample forecasting exercises.

Social consequences of planned relocation in response to sea level rise: impacts on anxiety, well-being, and perceived safety

Governments globally are adapting to sea level rise through a range of interventions to improve everyday lives of communities at risk. One prominent response is planned relocation, where people and communities are enabled to move from localities exposed to coastal erosion and inundation as a result of sea level rise. Managed retreat has significant social consequences including under-reported impacts on health, well-being and social identity. Here we adopt well-established measures of well-being and document the outcomes of planned relocation on well-being in the Volta Delta region of Ghana. Data from a bespoke survey for individuals (n = 505) in relocated and non-relocated communities demonstrate that planned relocation negatively impacts well-being and anxiety of those relocated when compared to a community that is equally exposed but has not moved. Individuals in the relocated community reported significantly lower levels of overall wellbeing, significantly higher levels of anxiety, and lower perceptions of safety, compared to non-relocated community members. These outcomes are explained as being related to the disruption of community connection, identities, and feelings of efficacy. Relocated community members reported significantly lower levels of attachment to the local area and home, significantly lower levels of community-based self-efficacy, and significantly lower levels of overall community-based identity. The results demonstrate that planned relocation to address sea level rise has multiple social consequences with outcomes for well-being that are not straightforwardly related to risk reduction.

Affective dynamics in mother-adolescent dyads: links to mental health and relationship quality

ABSTRACT Current research in developmental psychopathology has emphasised how emotion dynamics, such as affective variability, relate to psychosocial functioning. In this brief article, we examined mean differences in mothers’ and adolescents’ affective intensity and lability in positive and negative emotions and explored how these emotion dynamics related to depressive symptoms and mother-adolescent relationship quality. We administered individual surveys each day for one week to mother-adolescent dyads (N = 109) that inquired about positive and negative affective states. Affective intensity was measured by the mean across the week and lability by the standard deviation. Participants also reported on their depressive symptoms and adolescents reported on relationship quality. Results showed that positive affect was more intense and more variable than negative affect, and adolescents experienced more intense negative affective and less intense positive affect than mothers. Greater mother and adolescent negative affect intensity and less maternal positive affect intensity related to more depressive symptoms. Affective intensity in mothers and adolescents and affective lability in mothers related to mother-adolescent relationship quality. These findings extend the growing body of knowledge on individuals’ affective intensity and variability by considering family dynamics.

The relationship between positive airway pressure tolerance and adherence: defining a new metric.

Positive airway pressure (PAP) therapy adherence rates range from 30% to 60%, yet adherent patients may still express dissatisfaction with treatment. The identification of factors affecting PAP tolerance could provide insight into its impact on adherence. Patients with obstructive sleep apnea presenting for first follow-up visit after newly initiating PAP therapy were given a 10-question PAP tolerance survey encompassing domains of psychosocial perception, practical issues, and side effects, utilizing 10-point visual analog scales. Relationships between adherence data, tolerance scores, and patient variables (demographics, sleep-related factors, comorbidities, usage data) were explored via 2-tailed t tests, multivariable regression analysis, and recursive partitioning regression trees with a significance level of P ≤ .05. For 105 patients, tolerance scores were higher in patients considered adherent to therapy (P = .033), as were scores for individual survey questions addressing the ability to fall asleep (P = .013) and sleep through the night (P = .020). Depression positively (P = .006) and insomnia medication use negatively (P = .010) predicted tolerance score. Data-driven tolerance score cutoffs were identified to correlate with PAP adherence, with higher tolerance scores correlating with greater adherence rates. PAP tolerance may play an important role in therapy adherence. Tolerance can be statistically defined and categorized based on prior adherence data. Its utility as a predictive tool in assessing future adherence is warranted. Tekumalla S, Plawecki A, Kaffenberger T, etal.

Constraining the growth rate on linear scales by combining SKAO and DESI surveys

In the pursuit of understanding the large-scale structure of the Universe, the synergy between complementary cosmological surveys has proven to be a powerful tool. Using multiple tracers of the large-scale structure can significantly improve the constraints on cosmological parameters. We explore the potential of combining the Square Kilometre Array Observatory (SKAO) and the Dark Energy Spectroscopic Instrument (DESI) spectroscopic surveys to enhance precision on the growth rate of cosmic structures. We employ a multi-tracer Fisher analysis to estimate precision on the growth rate when using pairs of mock surveys that are based on SKAO and DESI specifications. The pairs are at both low and high redshifts. For SKA-MID, we use the HI galaxy and the HI intensity mapping samples. In order to avoid the complexities and uncertainties at small scales, we confine the analysis to scales where linear perturbations are reliable. The consequent loss of signal in each individual survey is mitigated by the gains from the multi-tracer. After marginalising over cosmological and nuisance parameters, we find a significant improvement in the precision on the growth rate.

Multidimensional well-being of US households at a fine spatial scale using fused household surveys

Social science often relies on surveys of households and individuals. Dozens of such surveys are regularly administered by the U.S. government. However, they field independent, unconnected samples with specialized questions, limiting research questions to those that can be answered by a single survey. The presented data comprise the fusion onto the American Community Survey (ACS) microdata of select donor variables from the Residential Energy Consumption Survey (RECS) of 2015, the National Household Travel Survey (NHTS) of 2017, the American Housing Survey (AHS) of 2019, and the Consumer Expenditure Survey - Interview (CEI) for the years 2015–2019. This results in an integrated microdataset of household attributes and well-being dimensions that can be analyzed to address research questions in ways that are not currently possible. The underlying statistical techniques, designed under the fusionACS project, are included in an open-source R package, fusionModel, that provides generic tools for the creation, analysis, and validation of fused microdata.

Patterns of Care in the Diagnosis and Management of Intracranial Atherosclerosis‐Related Large‐Vessel Occlusion: The Rescue‐LVO Survey

Background We aimed to determine the current practice patterns among neurointerventional practitioners frequently involved in treating intracranial atherosclerosis‐related large‐vessel occlusion (ICAS‐LVO) during mechanical thrombectomy. Methods We conducted an international online survey of neurointerventionalist members of the Society of Vascular and Interventional Neurology and Society of Neurointerventional Surgery. The 28‐question poll evaluated the preferences on diagnosis, treatment, and endovascular approach to ICAS‐LVO. Results A total of 184 individual survey responses were obtained from practicing neurointerventional physicians. Overall, 38.3% reported an incidence of 6% to 10% of ICAS‐LVO during mechanical thrombectomy. Most neurointerventionalists (91%) diagnose ICAS‐LVO after a continued or recurrent occlusion or by the presence of fixed focal stenosis after multiple mechanical thrombectomy attempts. Most respondents (86%) preferred acute treatment of ICAS‐LVO with rescue stenting (RS)±angioplasty. However, in patients who achieved recanalization with a severe fixed focal stenosis, most (58%) recommended primary medical management. The preferred medication during acute RS was intravenous antiplatelet therapy (65%), and after acute RS, it was dual oral antiplatelet therapy (65%). Fear of hemorrhagic complications (74%) was the most compelling reason not to perform RS±angioplasty. Of respondents, 24% were hesitant to randomize patients to acute RS versus medical therapy in a future randomized trial because of the lack of sensitive and specific biomarkers to diagnose ICAS‐LVO before mechanical thrombectomy treatment. Conclusions The findings of this survey highlight the variations in practice in the medical and endovascular management of ICAS‐LVO. In addition, it informs the situation of equipoise in the treatment decision in ICAS‐LVO, which can then be incorporated into the design of future randomized clinical trials.

Identifying vulnerable populations in urban society: a case study in a flood-prone district of Wuhan, China

Abstract. In the context of unprecedented extreme weather and climatic events, the internal structural factors of society play a decisive role in determining the extent to which human beings are affected by disasters and their ability to respond to them. In the past few decades, rapid urbanization in developing countries, such as China, has greatly increased social vulnerability. This process has generated uneven living conditions and created many vulnerable groups, including urban poverty, migrants, and socially and geographically marginalized groups. These groups face difficulties in living conditions, education, livelihood stability, and more. This study sets up indicators from a micro-perspective: three indicators of exposure, four indicators of sensitivity, and eight indicators of adaptive capacity. Based on this evaluation index system, this study conducted a social vulnerability assessment of the population in Hongshan District, Wuhan, China, through individual questionnaire surveys. K-means cluster analysis was used to determine high, medium, and low levels of social vulnerability, which were used to compare different community types and identify vulnerable groups. The results showed close interrelationships between different types of communities in terms of physical and built environments as well as varying levels of social vulnerability to disasters. The high-vulnerability group accounted for 12.9 % of the 599 samples, the medium-vulnerability group accounted for 48.4 %, and the low-vulnerability group accounted for 38.7 %. The higher-vulnerability groups exhibited characteristics such as low education, poor health, low annual income, unstable work, and insufficient social security. Quantitative understanding of the degree of dissimilarity in social vulnerability among different communities and populations is significant in reducing social vulnerability and disaster risk specifically and effectively.
