Measuring inequity: a systematic review of methods used to quantify structural racism
Abstract
Objective: To summarize the ways in which researchers have quantified measures of structural racism for the purposes of empirical, quantitative investigation of its associations with physical and mental health outcomes.
Methods: Systematic review of literature published January 1, 2007-June 30, 2017. We searched PubMed and EMBASE databases for studies including at least one of the following search terms in the title or abstract: “structural racism”, “systemic racism”, “institutional racism”, “institutionalized racism”. Excluded studies were not original research, not US based, did not quantify an explicitly named indicator of structural racism, or were qualitative designs. Data from full text articles were abstracted and synthesized.
Results: Twenty articles met the final inclusion criteria. Articles included measures of structural racism within the following domains: residential neighborhood/housing, perceived racism in social institutions, immigration and border enforcement, political participation, socioeconomic status, criminal justice, and workplace environment.
Conclusions: A burgeoning body of work suggest ways to operationalize and measure structural racism in US society for the purposes of exploring its impacts on individual and population health inequities

Impact of Small Group Size on Neighborhood Influences in Multilevel Models
Objective: Although there is a growing body of literature on sample size in multilevel or hierarchical modeling, few studies have examined the impact of group size < 5.
Design: We examined the impact of a group size less than five on both a continuous and dichotomous outcome in a simple two-level multilevel model utilizing data from two studies.
Setting: Models with balanced and unbalanced data of group sizes 2 to 5 were compared to models with complete data. Impact on both fixed and random components were examined.
Results: Random components, particularly group-level variance estimates, were more affected by small group size than were fixed components. Both fixed and random standard error estimates were inflated with small group size. Datasets where there are a large number of groups yet all the groups are of very small size may fail to find or even consider a group-level effect when one may exist and also may be under-powered to detect fixed effects.
Conclusions: Researchers working with multilevel study designs should be aware of the potential impact of small group size when a large proportion of groups has very small (< 5) sample sizes
Multimorbidity patterns and health-related quality of life in Jamaican adults: a cross sectional study exploring potential pathways
IntroductionMultimorbidity and health-related quality of life (HRQoL) are intimately linked. Multiple chronic conditions may adversely affect physical and mental functioning, while poorer HRQoL may contribute to the worsening course of diseases. Understanding mechanisms through which specific combinations of diseases affect HRQoL outcomes can facilitate identification of factors which are amenable to intervention. Jamaica, a middle-income country with high multimorbidity prevalence, has a health service delivery system dominated by public sector provision via a broad healthcare network. This study aims to examine whether multimorbidity classes differentially impact physical and mental dimensions of HRQoL in Jamaicans and quantify indirect effects on the multimorbidity–HRQoL relationship that are mediated by health system factors pertaining to financial healthcare access and service use.Materials and methodsLatent class analysis (LCA) was used to estimate associations between multimorbidity classes and HRQoL outcomes, using latest available data from the nationally representative Jamaica Health and Lifestyle Survey 2007/2008 (N = 2,551). Multimorbidity measurement was based on self-reported presence/absence of 11 non-communicable diseases (NCDs). HRQoL was measured using the 12-item short-form (SF-12) Health Survey. Mediation analyses guided by the counterfactual approach explored indirect effects of insurance coverage and service use on the multimorbidity–HRQoL relationship.ResultsLCA revealed four profiles, including a Relatively Healthy class (52.7%) characterized by little to no morbidity and three multimorbidity classes characterized by specific patterns of NCDs and labelled Metabolic (30.9%), Vascular-Inflammatory (12.2%), and Respiratory (4.2%). Compared to the Relatively Healthy class, Vascular-Inflammatory class membership was associated with lower physical functioning (β = −5.5; p < 0.001); membership in Vascular-Inflammatory (β = −1.7; p < 0.05), and Respiratory (β = −2.5; p < 0.05) classes was associated with lower mental functioning. Significant mediated effects of health service use, on mental functioning, were observed for Vascular-Inflammatory (p < 0.05) and Respiratory (p < 0.05) classes.ConclusionSpecific combinations of diseases differentially impacted HRQoL outcomes in Jamaicans, demonstrating the clinical and epidemiological value of multimorbidity classes for this population, and providing insights that may also be relevant to other settings. To better tailor interventions to support multimorbidity management, additional research is needed to elaborate personal experiences with healthcare and examine how health system factors reinforce or mitigate positive health-seeking behaviours, including timely use of services
Genetic sensitivity to the caregiving context: The influence of 5httlpr and BDNF val66met on indiscriminate social behavior ☆ , ☆☆
Evidence that gene × environment interactions can reflect differential sensitivity to the environmental context, rather than risk or resilience, is increasing. To test this model, we examined the genetic contribution to indiscriminate social behavior, in the setting of a randomized controlled trial of foster care compared to institutional rearing. Children enrolled in the Bucharest Early Intervention Project (BEIP) were assessed comprehensively before the age of 30 months and subsequently randomized to either care as usual (CAUG) or high quality foster care (FCG). Indiscriminate social behavior was assessed at four time points, baseline, 30 months, 42 months and 54 months of age, using caregiver report with the Disturbances of Attachment Interview (DAI). General linear mixed-effects models were used to examine the effect of the interaction between group status and functional polymorphisms in Brain Derived Neurotrophic Factor (BDNF) and the Serotonin Transporter (5htt) on levels of indiscriminate behavior over time. Differential susceptibility, relative to levels of indiscriminate behavior, was demonstrated in children with either the s/s 5httlpr genotype or met 66 BDNF allele carriers. Specifically children with either the s/s 5httlpr genotype or met66 carriers in BDNF demonstrated the lowest levels of indiscriminate behavior in the FCG and the highest levels in the CAUG. Children with either the long allele of the 5httlpr or val/val genotype of BDNF demonstrated little difference in levels of indiscriminate behaviors over time and no group × genotype interaction. Children with both plasticity genotypes had the most signs of indiscriminate behavior at 54 months if they were randomized to the CAUG in the institution, while those with both plasticity genotypes randomized to the FCG intervention had the fewest signs at 54 months. Strikingly children with no plasticity alleles demonstrated no intervention effect on levels of indiscriminate behavior at 54 months. These findings represent the first genetic associations reported with indiscriminate social behavior, replicate previous gene × gene × environment findings with these polymorphisms, and add to the growing body of literature supporting a differential susceptibility model of gene × environment interactions in developmental psychopathology

Neighbourhood alcohol availability and gonorrhea rates: impact of social capital
Social capital and income inequality have been proposed as important mediators of the relation between the
material environment and health outcomes. We determined whether indicators of social capital are (i) associated with
neighbourhood gonorrhea rates, and (ii) mediate the relation between alcohol outlet density and gonorrhea rate.
Longitudinal analyses of age- and sex-adjusted gonorrhea cases reported from 1990 to 1996 in the 445 census tracts
affected by the 1992 civil unrest in Los Angeles, California was conducted. The role of alcohol outlets was assessed
both as tracts with surrendered off-sale outlets due to the civil unrest and annual off-sale alcohol outlet density rates.
Tract level voting rates were used as one indicator of social capital, while neighbourhood structure conducive to social
organization was used as another. Neighbourhoods with greater voting over time and greater endogenous social organization
experienced 1.9 and 67.2 fewer gonorrhea cases per 100,000. Results also reveal a partial mediating role of
social capital on the relationship between alcohol outlet density and gonorrhea rate. The alcohol environment may have
a direct or partially mediated role in infectious disease outcomes such as gonorrhea. Our findings support the importance
of continuing controls and limits on off-premise alcohol outlet density, as a potential means of reducing gonorrhea
rates and increasing social capital
Building a Culture of Health Through the Built Environment: Adaptable Solutions to Community Well-Being
Characteristics of the built neighborhood environment have been associated with Action Area 1 drivers, but few studies have examined changes in built environment conditions on such drivers. The proposed project will: 1) test the effectiveness of a blight reduction intervention in cluster randomized controlled trial (RCT) on altering specific Action Area 1 drivers—well-being and health interconnectedness, sense of community, and civic engagement—as well as 2) test the causal relation between changes in the drivers and resultant health and social outcomes—specifically, family and youth violence, substance use and mental health. The RCT will be conducted over four years across neighborhoods experiencing high rates of poverty and violence in New Orleans, LA and coupled with qualitative data collection. Findings will provide critical information for policy and prevention efforts and will be immediately translated locally and easily adapted to other urban areas in the U.S
