Greater social cohesion is associated with lower body mass index among African American adults

Obesity remains a public health issue, especially for Blacks (or African Americans). Obesity is thought to reflect a complex interaction of socioenvironmental, biological, and cognitive factors. Yet, insufficient attention has been given to psychosocial factors like social cohesion within the African American community. Using multivariable linear regression, we examined the association between social cohesion, measured by the Social Cohesion and Trust scale, and body mass index (BMI) with cross-sectional data (n = 1467) from a cohort study (2008–2009). Greater social cohesion was associated with lower BMI (b = -0.88; 95% CI: −1.45, −0.32) in an unadjusted model. The association was strengthened after further adjusting for relevant covariates (i.e., individual-level sociodemographic factors, health behaviors, and depressive symptoms) (b = -1.26; 95% CI: −1.94, −0.58). Future research should examine potential mechanisms underlying the association between social cohesion and BMI with longitudinal data. In the meantime, obesity prevention and intervention measures should consider promoting social ties and bonds to lower BMI in African American communities

Parents’ perceived neighborhood safety and children’s cognitive performance:Complexities by race, ethnicity, and cognitive domain

Background:Aim: To examine racial/ethnic variations in the effect of parents’ subjective neighborhood safety on children’s cognitive performance. Methods: This cross-sectional study included 10,027 children from the Adolescent Brain Cognitive Development (ABCD) study. The exposure variable was parents’ subjective neighborhood safety. The outcomes were three domains of children’s cognitive performance: general cognitive performance, executive functioning, and learning/memory. We used mixed-effects regression models for data analysis. Results: Overall, parents’ subjective neighborhood safety was positively associated with children’s executive functioning, but not general cognitive performance or learning/memory. Higher parents’ subjective neighborhood safety had a more positive influence on the executive functioning of non-Hispanic White than Asian American children. Higher parents’ subjective neighborhood safety was associated with higher general cognitive performance and learning/memory for non-White children relative to non-Hispanic White children. Conclusion: The race/ethnicity of children moderates the association between neighborhood safety and cognitive performance. This becomes more complicated, as the patterns seem to differ across ethnicity and cognitive domains. It is unknown whether the observed racial/ethnic variations in the effect of neighborhood safety on cognitive performance are neighborhood characteristics such as residential segregation. Addressing neighborhood inequalities is needed if we wish to reduce racial/ethnic inequities in the cognitive development of children

A novel approach to model cumulative stress:Area under the s-factor curve

OBJECTIVE: Using a large longitudinal sample of adults from the Midlife in the United States (MIDUS) study, the present study extended a recently developed hierarchical model to determine how best to model the accumulation of stressors, and to determine whether the rate of change in stressors or traditional composite scores of stressors are stronger predictors of health outcomes.METHOD: We used factor analysis to estimate a stress-factor score and then, to operationalize the accumulation of stressors we examined five approaches to aggregating information about repeated exposures to multiple stressors. The predictive validity of these approaches was then assessed in relation to different health outcomes.RESULTS: The prediction of chronic conditions, body mass index, difficulty with activities of daily living, executive function, and episodic memory later in life was strongest when the accumulation of stressors was modeled using total area under the curve (AUC) of estimated factor scores, compared to composite scores that have traditionally been used in studies of cumulative stress, as well as linear rates of change.CONCLUSIONS: Like endogenous, biological markers of stress reactivity, AUC for individual trajectories of self-reported stressors shows promise as a data reduction technique to model the accumulation of stressors in longitudinal studies. Overall, our results indicate that considering different quantitative models is critical to understanding the sequelae and predictive power of psychosocial stressors from midlife to late adulthood.</p

Respiratory and mental health effects of wildfires: an ecological study in Galician municipalities (north-west Spain)

<p>Abstract</p> <p>Background</p> <p>During the summer of 2006, a wave of wildfires struck Galicia (north-west Spain), giving rise to a disaster situation in which a great deal of the territory was destroyed. Unlike other occasions, the wildfires in this case also threatened farms, houses and even human lives, with the result that the perception of disaster and helplessness was the most acute experienced in recent years. This study sought to analyse the respiratory and mental health effects of the August-2006 fires, using consumption of anxiolytics-hypnotics and drugs for obstructive airway diseases as indicators.</p> <p>Methods</p> <p>We conducted an analytical, ecological geographical- and temporal-cluster study, using municipality-month as the study unit. The independent variable was exposure to wildfires in August 2006, with municipalities thus being classified into the following three categories: no exposure; medium exposure; and high exposure. Dependent variables were: (1) anxiolytics-hypnotics; and (2) drugs for obstructive airway diseases consumption. These variables were calculated for the two 12-month periods before and after August 2006. Additive models for time series were used for statistical analysis purposes.</p> <p>Results</p> <p>The results revealed a higher consumption of drugs for obstructive airway diseases among pensioners during the months following the wildfires, in municipalities affected versus those unaffected by fire. In terms of consumption of anxiolytics-hypnotics, the results showed a significant increase among men among men overall -pensioners and non-pensioners- in fire-affected municipalities.</p> <p>Conclusions</p> <p>Our study indicates that wildfires have a significant effect on population health. The coherence of these results suggests that drug utilisation research is a useful tool for studying morbidity associated with environmental incidents.</p

Spread of a SARS-CoV-2 variant through Europe in the summer of 2020

[EN] Following its emergence in late 2019, the spread of SARS-CoV-21,2 has been tracked by phylogenetic analysis of viral genome sequences in unprecedented detail3,4,5. Although the virus spread globally in early 2020 before borders closed, intercontinental travel has since been greatly reduced. However, travel within Europe resumed in the summer of 2020. Here we report on a SARS-CoV-2 variant, 20E (EU1), that was identified in Spain in early summer 2020 and subsequently spread across Europe. We find no evidence that this variant has increased transmissibility, but instead demonstrate how rising incidence in Spain, resumption of travel, and lack of effective screening and containment may explain the variant’s success. Despite travel restrictions, we estimate that 20E (EU1) was introduced hundreds of times to European countries by summertime travellers, which is likely to have undermined local efforts to minimize infection with SARS-CoV-2. Our results illustrate how a variant can rapidly become dominant even in the absence of a substantial transmission advantage in favourable epidemiological settings. Genomic surveillance is critical for understanding how travel can affect transmission of SARS-CoV-2, and thus for informing future containment strategies as travel resumes.S

Racial Centrality May be Linked to Mistrust in Healthcare Institutions for African Americans

Evidence suggests that racial identity is an important component to African Americans\u27 self-concepts and therefore may be relevant to patients\u27 trust in healthcare, yet little is known as to how racial identity may influence trust or mistrust. African American adults (N = 220) in the greater Portland, Oregon, area provided survey reports of healthcare-related attitudes and experiences. Those who reported higher racial centrality had lower trust in healthcare institutions. Based on these findings, clinicians employing patient-centered care approaches should recognize racial identity as an important component to patients\u27 experiences when they seek to deliver equitable care to African American patients

African American Experiences in Healthcare: I Always Feel Like I\u27m Getting Skipped Over

Objective: Although African Americans perceive discrimination in health care settings, experience higher levels of medical mistrust compared with European Americans, and experience poorer communication with health care providers, little is known as to how these barriers to quality patient-provider relationships arise and manifest themselves. This study examined experiences of African American community members regarding these barriers and additionally explored participants’ perspectives on race in the patient-provider relationship. Methods: Focus groups were conducted as part of a study exploring participants’ experiences and relationships in health care settings. Sixty African American adults were recruited through community settings and activities to participate in 1 of 9 focus groups segmented by gender. Transcripts were reviewed for content related to perceived discrimination, mistrust, poor communication, and race discordance. Themes providing insight into participants’ subjective experience of these potential relationship barriers were derived through qualitative coding (using NVivo 10) and iterative discussion. Results: Perceived discrimination arose when African American patients, particularly women, felt their symptoms or problems were discredited. Medical mistrust occurred when clinicians did not convey respect to patients, leaving patients to wonder whether their clinician’s treatment was discriminatory or not. Poor communication arose when clinicians did not acknowledge patients’ perspectives during interactions. Patients often viewed these actions as discriminatory. Conclusions: African Americans experience poor communication with their health care providers, medical mistrust, and perceived discrimination when accessing health care in numerous and sometimes interrelated ways. The investigators recommend ways to reduce the experience of such barriers and to improve patient-provider relationships for African Americans in health care

Can Patient-Centered Communication Reduce the Effects of Medical Mistrust on Patients\u27 Decision Making?

Objective: Mistrust in medical institutions has been implicated as a barrier that disproportionately affects the quality of health care received by patients. Although patient-centered communication has been shown to improve patient-provider relationships, little is known as to whether it may reduce the effects of medical mistrust on patients’ decision-making and trust in physicians (physician mistrust). Method: In a laboratory study, 231 primary care patients (101 African American and 130 White participants) were randomly assigned to one of two conditions in which they viewed video recorded, standardized vignettes depicting a cardiologist recommending coronary bypass surgery to a patient diagnosed with angina and 3-vessel coronary artery disease. In each vignette, the cardiologist-actor demonstrated either low or high patient-centered communication behavior. Participants were asked to assume the role of the patient interacting with the video-recorded physician. Results: Hypotheses were partially supported. High levels of medical mistrust were associated with greater physician mistrust and lesser endorsement of the hypothetical bypass surgery. Among patients exposed to high patient-centered communication, the relationships between medical mistrust and both physician mistrust and surgery endorsement were weaker than among patients exposed to low patient-centered communication. Although African American patients reported greater medical mistrust compared with White patients, respondents’ race did not moderate the relationships. Conclusions: Results suggest that mistrust toward health care may unfavorably affect interactions and patients’ health-related outcomes. Physicians may buffer the effects of mistrust by using patient-centered communication skills such as soliciting the patient’s concerns and priorities and being responsive to the health care needs which patients identify.
