Neighborhood crime is differentially associated with cardiovascular risk factors as a function of race and sex.

Background: Neighborhood crime may be an important factor contributing to cardiovascular health disparities, and these relations may vary by race and sex. The present investigation evaluated (a) potential differential associations between neighborhood crime and cardiovascular disease (CVD) risk factors within subgroups of African American (AA) and White men and women, and (b) potential mediation by negative affect. Design and
Methods: Participants were 1,718 AAs and Whites (58% AA; 54% female; 59% above poverty; ages 30-64 years) living Baltimore, Maryland who completed the first wave of the Healthy Aging in Neighborhoods of Diversity across the Life Span study from 2004-2009. CVD risk factors included body mass index, total serum cholesterol, glucose, and systolic and diastolic blood pressure. A negative affect composite was comprised of self-reported depression, anxiety, anger, vigilance, and perceived stress. Hierarchical multiple regression analyses were used to examine associations between per capita overall and violent crime rates, negative affect, and CVD risk factors.
Results: There were significant associations of greater overall crime rate with higher fasting glucose (b=.192, P<0.05), and greater violent crime rate with higher systolic (b=86.50, P<0.05) and diastolic (b=60.12, P<0.05) blood pressure in AA women, but not men. These associations were not explained by negative affect. In Whites, there were no significant associations of overall or violent crime rates with cardiovascular risk factors. Conclusions: AA women may be particularly vulnerable to the negative impact of crime on cardiovascular risk. Preventative efforts aimed toward this group may help to deter the detrimental effects that living in a high crime area may have on one's cardiovascular health. ©Copyright: the Author(s), 2019.

Introduction

Cardiovascular disease (CVD) is the leading cause of death and disability in the United States for both men and women.[1] During the past several decades, research has established an association between lower socioeconomic status (SES) and greater CVD morbidity and mortality.[2] Individual SES factors such as poverty are often geographically concentrated.[3] Theories suggest that the environmental context within which one lives may play an important role in both defining and maintaining one’s SES.[3,4] Indeed, physical and social dimensions of neighborhood are associated with CVD risk factors independent of individual SES.[5-12] However, this research has examined mostly composite measures of neighborhood characteristics, whereas findings based on specific factors may be more directly translatable to intervention and prevention efforts.

Within the limited available research on specific neighborhood factors, considerable attention has been given to crime exposure, which has been associated with CVD risk factors and morbidity as well as various dimensions of negative affect.[13-19] CVD risk factors associated with crime exposure include greater blood pressure, heart rate, pulse rate reactivity, body mass index, metabolic syndrome (including elevated waist circumference and fasting glucose), triglyceride levels, C-reactive protein, low-density lipoprotein (LDL) cholesterol, and a composite measure of CHD risk including reduced high-density (HDL) and elevated total cholesterol. [15-18,20-31] Much of this research, however, examined crime exposure within children or adolescents, or homogeneous samples that are not generalizable to other populations.

Previous literature suggests that Blacks and Whites are differentially exposed to crime and that men and women have differential reactions to crime.[32-34] Likewise, CVD risk factors vary by race and sex.[35-39] These observations suggest that the associations between crime and CVD risk factors may differ across race and sex; an issue neglected in the literature thus far. Additionally, much of the literature has used only subjective self-reports of crime exposure or perceived safety. Information on crime prevalence collected by local government and police departments offer more objective measures of crime and may thus allow for more accurate implications of findings.

Because research has revealed associations of negative affect with both CVD and crime exposure, it may at least partially mediate the relation of the sociophysical environment to CVD.[40-43] Several studies have examined associations among individuallevel SES, negative affect, and CVD variables, but offer conflicting findings.[42,44-46] To our knowledge, only one study has examined sociophysical neighborhood factors, negative affect, and health outcome variables in the same statistical model. In that regard, Hill et al.[41] found that associations between a composite measure of neighborhood disorder (that included crime) and general health were mediated by depression and anxiety. To our knowledge, no study has examined whether measures of negative affect mediate the association between crime exposure and CVD or its risk factors.

The present study examined the association between objective crime exposure and risk factors for CVD within a racially and socioeconomically heterogeneous adult sample. We hypothesized that higher levels of neighborhood crime are associated with more pronounced CVD risk factors after adjusting for individual-level SES and other socio-demographic risk factors, behavioral factors, and medical comorbidities. We further hypothesized that this association is at least partially mediated by a composite measure of negative affect and perceived stress. Lastly, we explored whether associations might differ by race and sex.

Materials and Methods

Participants

Data for this study were derived from the first wave of the Healthy Aging in Neighborhoods of Diversity across the Life Span (HANDLS) study performed by the National Institute on Aging’s Intramural Research Program.[47] HANDLS is an ongoing longitudinal investigation of race and SES- related health disparities among AA and White adults aged 30-64 years residing in 13 Baltimore neighborhoods pre-selected based on their likelihood to yield representative distributions of race and sex across a range of socioeconomic circumstances.[42,47] A total of 2,800 participants completed both phases of the first wave of the study which took place from 2004-2009.

Medical exclusions for the study were individuals who were: 1) currently pregnant; 2) within 6 months of receiving chemotherapy, radiation, or biological treatments for cancer; 3) diagnosed with AIDS; 4) unable to provide informed consent; 5) currently using illegal/illicit drugs; or 6) with uncontrolled high blood pressure (>160/100). Please refer to previous publications for additional study exclusions.[47] The current analyses further excluded individuals: 1) who did not complete all psychosocial measures (n= 586); 2) with a history of stroke (n=60), dialysis (n=1), dementia (n=4), or cancer (n=250); 3) with a current diagnosis of chronic or severe cognitive or psychiatric conditions including schizophrenia (n=39) and bipolar disorder (n=128); 7) with a current diagnosis of neurological conditions including Parkinson’s Disease (n=3), Alzheimer’s Disease (n=0), epilepsy (n=99), and multiple sclerosis (n=5); or 6) who were not fasting at the time their labs were drawn (n=178). After these additional exclusions, 1,718 of the 2,800 participants remained.

Participants were identified during the first phase of the study by trained field interviewers who went door-to-door to gather demographic information. Based on an area probability sample, randomly selected residents were invited to participate in the study and, upon informed consent, were administered a household and nutritional survey, which included self-reported demographic questions. The second phase took place on a Medical Research Vehicle (MRV) which visited each of the 13 neighborhoods. During this visit, medical personnel conducted a medical history and physical exam, and administered a series of psychological assessments.

Measures

Demographic variables

Participants self-reported their race (1 = AA, 0 = White), sex (1 = men, 0 = women), education (years), and length of residence (years in current home). Poverty status was characterized as a family income less than 125% of the Federal poverty threshold and coded as 1, “poverty” and those with a family income greater than or equal to 125% of the poverty threshold were coded as 0, “not poverty.”

Characterization of exposure to crime

The HANDLS study used 2000 census tract data to define its 13 neighborhoods as contiguous groups of tracts. Crime statistics were made available by the Baltimore Neighborhood Indicators Alliance – Jacob France Institute of the University of Baltimore which provided the total number of overall and violent crime events for 2000 census tract neighborhoods from 2000-2008. Overall crime was defined as incidents of homicide, rape, aggravated assault, robbery, burglary, larceny, and auto theft that were reported to the Police Department. Violent crime was defined as the number of overall crimes identified as being violent (homicide, rape, aggravated assault, and robbery) that were reported to the Police Department. Cumulative overall and violent per capita crime rates were calculated for each participant by summing annual crime rates (total annual crime per capita based on 2000 population) for their census tract of residence for the four years before their year of enrollment.

Behavior/lifestyle factors

Alcohol and drug status were determined such that 0 = not current user (includes never tried, never used regularly, and used > 6 months ago) and 1 = used within the last 6 months. Smoking status was categorized such that 0 = not current smoker (includes never smoked, experimented with <100 cigarettes, and former smoker) and 1 = current smoker.

Psychological factors

Perceived stress was measured by Cohen’s 4-item Perceived Stress Scale and depressive symptoms were measured by the Center for Epidemiological Studies Depression Scale (CESD). [48,49] The generalized anxiety disorder subscale of the Psychiatric Diagnostic Screening Questionnaire (PDSQ) was used to measure anxiety.[50] Vigilance, as characterized by the need to chronically monitor the environment for threatening cues, was measured by a subscale of the Multiscale Measure of Reactive Responding, and anger was measured by a subscale of the Buss and Perry Aggression Questionnaire.[51,52]

Anthropometric measures

Body mass index (BMI) was calculated for each participant by dividing their measured weight by their measured height (kg/m[2]).

Comorbidity covariates

Data on potentially confounding premorbid medical conditions were grouped into clusters. Diabetes mellitus, thyroid disease, kidney disease, hepatitis, lupus, and HIV/AIDS were included in the diabetes mellitus, metabolic, and infectious disorders (DMMI) cluster. History of coronary artery disease, myocardial infarction, peripheral artery disease, atrial fibrillation, angioplasty, carotid endarterectomy, and coronary artery bypass surgery were included in the cardiovascular disease (CVD) cluster. All medical conditions were dichotomized. The cluster variables were calculated by summing these scores across conditions within the clusters. Additionally, BMI was used as a covariate when it was not used as a dependent variable. Use of psychotropic and anti-hypertensive medications were included as covariates for all analyses and use of statins was included as a covariate for the TSC analyses

Metabolic measures

Fasting blood samples were obtained for assessment of total serum cholesterol (TSC)and glucose (GLU). TSC and GLU were derived spectrophotometrically.

Hemodynamic measures

The brachial artery auscultation method was used to measure systolic and diastolic blood pressure (SBP, DBP). Measures were obtained with the arm at a 90-degree angle, palm facing up. One measure was obtained in each arm; these measures were averaged for analyses.

Data analyses

Missingness was examined for all of the variables. Data for all of the dependent variables except BMI (no missing data) were imputed with predicted values based on regression estimations using age, sex, race, and poverty status. These variables all had less than 10% missing by sex, race, and poverty status subgroups. The only remaining variables that had missing values were education (n = 42), length of residence (n = 377), and use of statins (n = 135). Given the large sample size, regressions were run using listwise deletion to account for this missing data. Variables were also examined for normality. Length of residence, TSC, and glucose were found to be non-normal and were log10 transformed in efforts to normalize distributions.

Since previous findings have suggested that psychosocial stressors tend to cluster together and that their combined effect may lead to even higher risk for cardiovascular events, it was expected that perceived stress, vigilance, anger, anxiety, and depression would be closely related and would represent a cumulative emotional burden.[53] A principle components analysis (PCA) of these measures indeed yielded one component extracted based on Kaiser-Guttman criterion.[54] The component, on which factor loadings ranged from .56 to .82, was used in the analyses to account for the five psychosocial measures.

We stratified rather than examined interactions of crime by race and sex because of the likelihood of differential confounding as well as differential mediation mechanisms by race and sex. After stratifying the sample by race and sex, we conducted a series of hierarchical multiple regressions to assess relations between overall crime rate, negative affect, and each CVD risk factor. The first step of the models included overall crime rate and demographic variables (age, education, poverty status, and length of residence) to determine the effect of overall crime rate on each cardiovascular risk factor after controlling for common covariates. The second step included both comorbidity clusters (CVD and DMMI) and medication use, and the third step included alcohol, drug, and smoking status as well as BMI (except for and BMI analyses) to determine if any associations between crime and cardiovascular risk factors remained after further adjustment. The fourth and final step included the negative affect component to examine potential mediation. A second series of identical hierarchical multiple regressions were conducted with violent crime rate. An α level of 0.05 was used to determine statistical significance.

Results

Descriptive statistics

Descriptive statistics for all variables by race and sex are provided in Table 1. The average per capita overall crime rate across all participants was .30 and the average per capita cumulative violent crime rate was .08. This means that on average, 300 overall crimes were reported per every 1000 residents living in a given participant’s census tract during the 4 years before their enrollment in the HANDLS study, and approximately 80 of those crimes were coded as violent.

Hierarchical regressions

Results showed a main effect of overall crime on GLU and of violent crime on SBP and DBP in AA women. In AA women only, greater overall crime rate was associated with higher GLU (b=.19, t(420)=2.62, P<.05, r[=.014) and greater violent crime rate was associated with higher SBP (b=86.504, t(420)=2.36, P<.05, r[=.011) and DBP (b=60.12, t(420)=2.49, P<.05, r[=.014). These associations were not attenuated by negative affect. In AA men and Whites, there were no significant associations of overall or violent crime rates with any of the cardiovascular risk factors (results not shown). Complete regression results are reported in Tables 2-4.

Discussion

We found that for AA women, living in an area of greater overall crime was associated with higher GLU, and living in an area of greater violent crime was associated with greater SBP and DBP. These findings were independent of select individual-level SES and other socio-demographic risk factors, behavioral factors, and medical comorbidities. That significant associations were only present for AA women suggests that this subset of the population may be particularly vulnerable to the health consequences of neighborhood crime. The results further suggest that blood pressure and glucose levels may be particularly sensitive to crime exposure among AA women, although the cross-sectional design of this study prevents us from making any inferences regarding temporal direction.

In support of the present results, previous findings suggest that neighborhood stressors may at least partially explain racial differences in hypertension prevalence, an important consequence of elevated blood pressure.[36] Furthermore, in a study by Wilson et al.,[19] violence exposure was associated with elevated nighttime blood pressure among AA adolescents. Although there have been no direct examinations of crime and fasting glucose, Baldock et al.[23] found that the metabolic syndrome (including elevated fasting glucose) was associated with greater perceived neighborhood crime in a sample of middle-aged men and women. In another study, a short-term spike in burglary rates was associated with increased C-reactive protein (which has been positively associated with glucose levels),[24] although associations were observed for men, but not women.[55]

Research has suggested that women may be particularly vulnerable to the health consequences of crime exposure due to their greater concern for personal safety. Thus, a negative response to crime in the form of psychosocial distress might contribute to elevated CVD risk factors among women.[32,33,56] However, contrary to our hypothesis, the associations between neighborhood crime and CVD risk factors in AA women were not mediated by a negative affect component comprised of measures of perceived stress, vigilance, anger, anxiety, and depression. Although previous findings demonstrated that the association between a composite measure of neighborhood disorder and general health was mediated by depression and anxiety, to our knowledge, no previous investigations examined whether psychosocial factors mediate the relation of neighborhood crime to health outcomes. One reason for this unexpected finding could be that the psychosocial vulnerability component may be too general a construct. Discrete measures of emotionality may be more pertinent to the relation of crime to health outcomes. [40,57] This will be an important area for future study.

It is unclear why overall crime, and not violent crime, was associated with increased glucose levels and why violent crime, and not overall crime was associated with increased blood pressure. There may be something fundamentally different about the mechanism by which overall crime, which includes violent crime as well as more petty general crimes, affects one’s health. Perhaps due to the increased frequency, overall crime represents more of a cumulative, sustained stressor which may be interpreted very differently from a less frequent, more severe stressor such as violent crime. Future research should aim to explore the underlying mechanisms that contribute to the variation in findings.

Study strengths and limitations

Strengths of this analysis include the large heterogeneous sample offered by the HANDLS study which samples representatively across a range of race, sex, age, and SES combinations. To our knowledge, this is the first study to separately examine participants by race and sex in associations between crime and cardiovascular risk factors. In addition, previous research has often failed to recognize the complex set of individual-level potential confounds thought to drive many of the associations between neighborhood level factors and health outcomes. By including a wide range of individual-level factors, the present study’s enhanced attention to the potential role of confounding variables further strengthens confidence in the findings.

The present analysis also has several important limitations, including its cross-sectional design. Future studies should examine prospective associations in order to establish temporal direction. Further, within-census tract variance in exposure to crime may hinder our ability to examine any true associations between prevalence of crime and CVD risk factors. By using objective crime, we assume “exposure” to crime equally within a given census tract. An argument has been made for the use of objective crime because of its resistance to subjective bias, however the perception of crime may drive the association between neighborhood crime and CVD risk factors regardless of its actual prevalence.[58] In addition, selfreport crime data can be further differentiated into categories reflecting how the crime is experienced such as victimization, witnessing, and hearing about it.[16] The relative importance of the perception of crime compared to objective crime should be a focus of future research.

The fact that all participants resided in urban inner-city neighborhoods where the prevalence of immeasurable characteristics of the environment may contribute to residual confounding is another limitation. Drug use may be one such factor as drug users tend to be more likely to live in areas of higher crime and tend to have overall metabolic profiles that make them appear seemingly healthier because of appetite suppression.[59] Given that drug use was a self-report measure in the present study, we may not have an accurate assessment of drug use. Future studies should include more objective measures of drug use and be careful to consider associations between drug use and the variables of interest. Also, the present findings are only generalizable to urban-dwelling AAs and Whites.

Conclusions

Although previous research found associations between neighborhood environment and cardiovascular risk factors, little is known about the specific neighborhood factors that may be contributing to these associations. The present study lays the groundwork for a better understanding of neighborhood effects by revealing several important associations between a specific neighborhood characteristic, objective crime, and CVD risk factors among sociodemographic subgroups known to differ in CVD outcomes. Our findings suggest that crime may be an important characteristic of the neighborhood environment that affects cardiovascular health and may also be an important contributor to differential risk factor associations across race and sex. AA women may be particularly vulnerable to the association between neighborhood crime and cardiovascular risk factors. The results contribute to our understanding of the highly complex multilevel CVD risk factor model, and most importantly, uncover target areas for prevention and intervention. Routine screening for elevated blood pressure and fasting glucose levels amongst AA women living in high crime neighborhoods may help to identify those at greater risk for CVD before disease endpoints are reached. Furthermore, preventative efforts aimed toward this group may help to deter the detrimental effects that living in a high crime area may have on one’s cardiovascular health. Policies should focus on increasing such efforts within higher crime communities.
