Studies on ethnic diversity and social cohesion are predominantly cross-sectional. Relying on longitudinal data from the German Socio-Economic Panel and applying a differences-in-differences design, this paper investigates how the event of moving to a more or less diverse neighbourhood affects people’s opinions about immigration up. This longitudinal design not only excludes reverse causality, but also renders unobserved heterogeneity a very unlikely alternative explanation. We show that individuals who move to a more diverse neighborhood are about 13% more likely to become very concerned about immigration. This effect remains even three years after the move. Because individuals who move to equal or lower diversity neighborhoods do not change their attitudes, it is not the event of moving as such that makes people more negative towards out-groups. Moreover, this study is the first to investigate whether previous experiences with diversity eliminate any threat effects of moving to a more diverse place. Interestingly, our results lend only partial support for this hypothesis, since those who to the top 15 per cent most diverse neighborhoods generally do not change their views. We consider whether this particular null-effect might be due to ‘threat immunity’ of such movers. Our sensitivity analyses questions this objection and instead suggests that populations often thought to be immune to threat seem to respond similarly.

Sectional Analysis

Abstract Metabolically healthy obesity (MHO) might be an alternative valuable target in obesity treatment. We aimed to assess whether alternative Mediterranean (aMED) diet and Dietary Approaches to Stop Hypertension (DASH) diet were favorably associated with obesity and MHO phenotype in a Chinese Multi-Ethnic population. We conducted this cross-sectional analysis using the baseline data of the China Multi-Ethnic Cohort (CMEC) study that enrolled 99 556 participants from seven diverse ethnic groups. Participants with self-reported cardiometabolic diseases were excluded to eliminate possible reverse causality. Marginal structural logistic models were used to estimate the associations, with confounders determined by directed acyclic graph (DAG). Among 65 699 included participants, 11.2% were with obesity. MHO phenotype was present in 5.7% of total population and 52.7% of population with obesity. Compared with the lowest quintile, the highest quintile of DASH diet score had 23% decreased odds of obesity (OR = 0.77, 95% CI: 0.71-0.83, Ptrend <0.001), and 27% increased odds of MHO (OR = 1.27, 95% CI: 1.10-1.48, Ptrend =0.001) in population with obesity. However, aMED diet showed no obvious favorable associations. Further adjusting for BMI did not change the associations between diet scores and MHO. Results were robust to various sensitivity analyses. In conclusion, DASH diet rather than aMED diet is associated with reduced risk of obesity and presents BMI-independent metabolic benefits in this large population-based study. Recommendation for adhering to DASH diet may benefit the prevention of obesity and related metabolic disorders in Chinese population.

The association between local ethnic composition and social cohesion has received widespread scholarly attention. Studies consistently find negative associations between neighborhood-level ethnic diversity and neighborhood cohesion indicators. However, hypotheses are formulated statically, empirical analyses rely mostly on cross-sectional data, and scholars worry about potential selection effects into and out of neighborhoods. This study presents a way to overcome these issues. The article derives hypotheses about how individuals' contact with their neighbors develops over time. Then, it examines trajectories of contact experiences by asking a clearly defined causal question: How would contact develop due to ethnic composition if households did not leave their neighborhood? The findings show a substantial increase in perceived contact quality and the probability to visit neighbors after staying in a neighborhood for five years, particularly in neighborhoods with high shares of ethnic minorities. These findings are at odds with theoretical accounts that suggest “hunkering down” in diverse contexts. However, findings also suggest that perceptions of a cohesive community do not increase in diverse neighborhoods. Taken together, the findings indicate that basic social interaction guided by reciprocity and close individual contacts are possible in ethnically diverse contexts.

Abstract Self-employed workers are often reported to have better health than salaried workers. Whether this is because self-employment has health benefits or healthier workers are self-employed is not clear. Self-employed workers may have higher job satisfaction due to higher levels of self-efficacy and autonomy, but may also experience higher job stress, uncertainty, and lack of health insurance leading to mental health problems. Self-employed workers in the U.S. may have different characteristics than those in Mexico and Korea given different working and living environments as well as different institutional arrangements. This study will examine the association between self-employment and mental and cognitive health for older adults in the U.S., Mexico, and South Korea. It uses harmonized panel data from the Health and Retirement Study, the Korean Longitudinal Study of Aging, and the Mexican Health and Aging Study. We compare the health and selection effect of self-employment using a pooled logistic model, fixed-effects model, and a bivariate probit model. In addition to comparing self-employed and salaried workers, we analyze differences between self-employed with and without employees. By using rich data and various models, we address reverse causality and estimate the relationship between self-employment and health. We show that the positive health effects of self-employed workers in the U.S. disappear once controlled for unobserved heterogeneity, indicating the possibility of healthier workers selecting into self-employment. Interestingly, for Korea and Mexico, healthier individuals seem to select into wage work which reflects the difference in working conditions across countries. Further analysis will show effects by business size.

Abstract This review analyzed the studies that evaluated cardiovascular health indicators (blood pressure, waist circumference, heart rate, glucose index and lipid blood) in recreational soccer players during adolescence, and identify possible associated factors. The search was performed in the electronic databases (PubMED, SciELO, LILACS, Scopus, SPORTDiscus and Web of Science). Inclusion criteria were: population composed of children and/or adolescents (10–19 years or average age up to 19 years); studies adolescents engaged in recreational soccer regularly and observational studies with cross-sectional or longitudinal design. The process of analysis of studies involved reading titles, abstracts and full texts. After these phases, seven articles were eligible. Regarding the design, all studies were cross-sectional. Of the total studies included, five presented moderate methodological quality values and two presented low methodological quality values, according to National Heart, Lung, and Blood Institute instrument. The most cardiovascular health indicators used in recreational soccer players during adolescence was waist circumference; three studies analyzed heart rate, two evaluated blood pressure, one analyzed insulin resistance and none of the included studies analyzed lipid profile. Factors associated were analyzed in four studies, being that sedentary time and body mass index (BMI) present association with at least one indicator of cardiovascular health.

AbstractObjectivesFibromyalgia is a chronic widespread pain (CWP) syndrome of unknown etiology with substantial burden of illness and functional impairment. Pain acceptance has emerged as an interesting target of therapy in chronic pain populations, but few studies have yet been done on the effect of pain acceptance on patients with fibromyalgia. The aim of the present study was to examine the relationship between pain acceptance and its impact on function and symptoms in fibromyalgia with both a cross-sectional and longitudinal design.MethodsThree hundred and sixty five participants aged 22–70 with fibromyalgia were recruited from the Norwegian Fibromyalgia Association (NFA). They filled out a questionnaire containing the Fibromyalgia Impact Questionnaire (FIQ), measurement of function and symptoms, and Chronic Pain Acceptance Questionnaire (CPAQ), measurement of pain acceptance, in addition to sociodemographic and clinical variables such as degree of fibromyalgia, depression and pain duration (T1 measures). One year after, 87 of the participants filled out the FIQ and clinical measures once again (T2 measures). Unadjusted and adjusted linear regression analyses were performed both for cross-sectional measures at T1 and for longitudinal measures from T1 to T2, with FIQ score as the outcome variable and CPAQ score at T1 as one of the main independent variables.ResultsHigher CPAQ score was significantly associated with a lower FIQ score at T1, also when adjusting for age, education, work, depression and Fibromyalgianess Score (p<0.01). Lower FIQ score indicate less impact of fibromyalgia on functioning. In addition, two adjusted linear regression models found higher pain acceptance (CPAQ score) at T1 to be associated with lower negative impact of fibromyalgia on function and symptoms (FIQ score) at T2 (p<0.01).ConclusionsHigher pain acceptance is associated with better functional level and less symptoms in fibromyalgia, both cross-sectionally and when measurements are separated in time. Further research should include experimental studies with acceptance-based interventions for this patient group.

ObjectiveTo assess the level of knowledge about blood donation and associated factors in Ethiopia.DesignSystematic review and meta-analysis.MethodsBoth published and unpublished cross-sectional studies on the level of knowledge about blood donation in Ethiopia were included. Articles from different databases such as PubMed/MEDLINE, HINARI, EMBASE, Scopus, Google Scholar and African Journals Online were searched. Cochrane I2 statistics were used to check for heterogeneity. Subgroup and sensitivity analyses of evidence of heterogeneity were carried out. Egger’s test with funnel plot was conducted to investigate publication bias.ResultTwenty cross-sectional studies with a total of 8338 study participants (4712 men and 3626 women) were included. The overall nationwide level of knowledge about blood donation was 56.57% (95% CI 50.30 to 62.84). Being in secondary school and above (adjusted OR=3.12; 95% CI 2.34 to 4.16) and being male (adjusted OR=1.81; 95% CI 1.44 to 2.28) were the factors associated with level of knowledge about blood donation.ConclusionMore than half of the study participants were knowledgeable about blood donation. Sex and educational status were the factors significantly associated with level of knowledge about blood donation in Ethiopia. Therefore, there is a need for education and dissemination of information about blood donation among the general population to build adequate knowledge and maintain regular blood supply.

Background Increasing evidence highlights potential associations between varus thrust and health domains associated with knee osteoarthritis (OA). Objective The aim of this study was to investigate the association between varus thrust and 2 subcategories—“pain and stiffness” and “activities of daily living (ADL)”—of the Japanese Knee Osteoarthritis Measure (JKOM). Design This was a cross-sectional study. Methods In total, 296 outpatients with knee OA visiting orthopedic clinics were enrolled. The inclusion criteria were age ≥50 years, medial knee OA and Kellgren-Lawrence (K/L) grade ≥1 in one or both knees, and the ability to walk independently. Standard posterior-anterior knee radiographs were measured for varus alignment. Participants were video recorded while walking and were evaluated for the presence or absence of varus thrust. Pain and stiffness of the knee joint and ADL were evaluated using the JKOM. Multivariate regressions (outcomes: pain and stiffness and ADL; predictor variable: varus thrust) were performed. Results Varus thrust was present in 46 (16.2%) of 284 patients. Multivariate regression analyses demonstrated that varus thrust is independently associated with pain and stiffness, adjusted for age, sex, body mass index, K/L grade, and varus alignment (β=.17, P=.005). However, the association between varus thrust and ADL was not significant (β=.11, P=.058). Based on sensitivity analyses, including participants of K/L grade 1 had little influence on this analysis. Limitations Only 16.2% of participants had a varus thrust. Moreover, a cause-effect relationship between varus thrust and pain and stiffness remains unknown due to the cross-sectional design of this study. Conclusions Varus thrust was associated with pain and stiffness in patients with medial knee OA. However, the association between varus thrust and ADL did not reach significance.

Abstract Importance There is a lack of peer-reviewed literature on leadership development programs (LDP) in ophthalmology. Research into LDP demographics, outcomes, and methodology is needed. Objective The aim of the study is to evaluate the extent to which LDPs targeting ophthalmologists meet the needs of emerging leaders. Design The design type of the study is cross-sectional analysis. Setting This study involves international setting. Participants The participants involved were ophthalmologists at any career level. Methods Routine internet search was used to identify LDPs targeting ophthalmologists. LDPs identified were categorized by the outcome data available into four levels based on prior literature. Participants were assessed using previously validated software for gender (Gender-API, 2020) and race or ethnicity (NamSor, 2020) Results Nine programs were identified which were classified into LDP generations. The first LDP in ophthalmology was the American Academy of Ophthalmology (AAO) LDP, which served as the nidus for the formation of four multinational LDPs, together forming the Global LDP. These LDPs were similar in size and scope; program size ranging from nine to 30 participants; a length of 1 to 2 years; with similar curricular offerings; with funding primarily derived from cost-sharing with a nominating society. The second generation of ophthalmology LDPs in the United States has targeted female scientists or faculty (Women's LDP by ARVO) and academic ophthalmology leaders (Academic LDP by Association of University Professors of Ophthalmology).The AAO's LDP appears increasingly diverse with approximately 13% women at inception, gradually increasing from 40 to 65% women in the last 5 years (n = 389). There has also been a notable increase in ethnic diversity. Conclusion and Relevance AAO LDP is the preeminent leadership training program for ophthalmologists, and it has influenced the creation of a new generation of LDP offerings. There remains a paucity of LDP evaluation metrics and reported outcomes. Newer iterations are successfully targeting academic leadership and attempting to address known disparities in gender and race or ethnicity. Further expansion of LDPs and related research can ensure equity and diversity in the pipeline.

Excessive salt intake is a risk factor for hypertension. The most reliable method for estimating daily salt intake is measurement of 24-h urinary sodium excretion, while it is inconvenient. Sodium-to-potassium ratio (Na/K) of a urine sample is another index of salt loading. We previously reported that a simple measure of spot urine Na/K might be a representative of salt loading in a cross-sectional setting. Here, we conducted a longitudinal study aiming to clarify a prognostic significance of spot urine Na/K for increasing blood pressure (BP) levels. Study subjects consists of 9,769 general individuals. Among them, individuals whose baseline Na/K was available (n=9,328), who were normotensive at baseline (n=6,392), and who participated in the follow-up measurement (n=5,209) were included in this analysis (51.8±12.9 years old, male: 29.2%). Mean follow-up duration was 5.0±0.5 years. Mean Na/K at baseline was 3.1±1.7, and showed step-wise increase with BP levels (optimal: 3.0±1.6, normal: 3.3±1.8, high normal: 3.4±1.8, P<0.001). Other major factors that were significantly associated with Na/K was fasting time (r=-0.220, P<0.001), and CKD (CKD (n=694): 2.7±1.6, control: 3.2±1.7, P<0.001). Mean SBP was significantly increased during follow-up period (baseline: 116±12, follow-up: 119±15 mmHg), and 805 individuals (15.5%) were newly diagnosed as hypertension (HT). These individuals were significantly older (HT: 60.3±9.9, NT: 50.3±12.8 years), were frequently male (36.4%, 27.9%), and had higher SBP (127±9, 115±11 mmHg) at baseline (P<0.001). In contrast, baseline spot urine Na/K was slightly lower in individuals who developed HT (3.0±1.6, 3.1±1.8, P=0.013), while that measured at follow-up investigation was oppositely higher in hypertensives (3.1±1.8, 2.8±1.5, P<0.001). Multiple linear regression analysis adjusted for the covariates identified baseline Na/K (β=0.108, P<0.001) and changes in Na/K during follow-up period (β=0.222, P<0.001) as independent determinants for future SBP levels. Higher spot urine Na/K, as well as increases in the Na/K levels, was significant determinant for future BP levels. The apparently lower baseline Na/K levels in individuals who developed HT might be due to reverse causality.
