Depressive Symptoms Mediate the Association Between Fear of Crime and Higher Body Mass Index Gergana Kodjebacheva, PhD; Maria Koleilat, DrPH, MPH; Daniel J. Kruger, PhD Abstract Purpose. To investigate pathways in the association between fear of crime and obesity. Design. A cross-sectional survey was administered among residents aged 18 years and older across all Census tracts. Setting. Genesee County, Michigan. Subjects. A total of 3192 residents. Measures. Body mass index (BMI) was calculated by using the respondents’ reported height and weight. Composite fear-of-crime and depressive symptoms scores were calculated by using several survey items. Analysis. Path analysis examined the effects of fear of crime on BMI. Results. Fear of crime was associated with higher BMI. Depressive symptoms mediated the relationship between fear of crime and BMI (p , .001). Moderate exercise mediated the association between depressive symptoms and BMI (p , .001). Conclusion. Fear of crime was associated with depressive symptoms, which in turn were associated with reduced exercise and subsequently higher BMI. (Am J Health Promot 2015; 30[2]:130–132.)

PURPOSE Fear of crime is defined as the ‘‘state of alarm engendered by the belief that one is in danger of criminal victimization.’’1 It can be caused by neighborhood conditions such as poverty, vandalism, and public drinking.2,3 One consequence of fear of crime may be increased body mass index (BMI). Several hypotheses explain the association between fear of crime and obesity. Because people who fear crime avoid parks and walking trails,2 one hypothesis is that fear of crime leads to reduced exercise, thus contributing to obesity. Another hypothesis is that fear of crime leads to depressive symptoms, which increase cortisol levels and promote the storage of fat in the body.3 Yet another hypothesis is that depressive symptoms lead to obesity through discouraging exercise.3 Studies offer mixed support for these hypotheses. Fear of crime was not associated with obesity in some research.4 In another study, which overrepresented females and non-Hispanic whites, fear of crime was associated with depressive symptoms, which in turn were related to reduced exercise and subsequently obesity.3 The present study investigated the association between fear of crime and higher BMI by using a demographically representative survey in Genesee County, Michigan.

METHODS Design and Sample Genesee County has experienced economic decline due to the closure of automobile-manufacturing plants. The rate of violent crime increased between

2000 and 2011.5 To assess residents’ health, the Speak to Your Health! survey was developed.5–7 The survey was either administered over the telephone or in person or was mailed to a random sample of residents aged 18 years and older across all residential Census tracts in Genesee County. The survey response rate was 25%. The study was approved by the University of Michigan Behavioral Sciences Institutional Review Board. Three waves of survey data (2007, 2009, and 2011) were combined into a sample of 3192 adults. Measures BMI was calculated by using the respondents’ reported height and weight. A composite fear-of-crime score was calculated by using these items: (1) How fearful are you about crime in your neighborhood? (2) How safe is it to walk around alone in your neighborhood during the daytime? (3) How safe is it to walk around alone in your neighborhood after dark? and (4) Compared to other neighborhoods, the crime rate in your neighborhood is (very high to very low).8 The fear-ofcrime scale had a Cronbach a of .86. The depressive symptoms Brief Symptoms Inventory subscale9 asked participants how often during the past week they felt (1) lonely, (2) blue or sad, and (3) they had no interest in things. It had a Cronbach a of .89. Physical activity was categorized by the number of days a week the respondent engaged in activity, using two Behavioral Risk Factor Surveillance System questions: (1) How many days per week do you engage in moderate physical activity

relationship between fear of crime and BMI (Sobel test ¼ 3.97, p , .001). They accounted for 17% of the relationship between fear of crime and BMI. Moderate exercise mediated the relationship between depressive symptoms and BMI (Sobel test ¼ 4.26, p , .001).

(such as brisk walking, bicycling, gardening) for at least 10 minutes at a time? (2) How many days per week do you engage in vigorous physical activity (such as running, aerobics, and heavy yard work) for at least 10 minutes at a time?10 Analysis All statistical analyses were performed with Amos 21 (IBM SPSS 2012, Armonk, New York). Path analysis divided the total effect of fear of crime on BMI into direct effect and indirect effects mediated by depressive symptoms and exercise. Exercise was also allowed to mediate the relationship between depressive symptoms and BMI. The Sobel test assessed if the paths were statistically significant. The analysis was adjusted for age, gender, race/ethnicity, and education.

RESULTS The mean (6 SD) age and years of education of study participants were: 55 (6 16) years and 12 (6 2) years, respectively. The mean (6 SD) BMI was: 29 (6 7). A total of 1427 participants (44.7%) were African-American and 1765 (55.3%) were non-Hispanic white. Females were more likely to report fear of crime than males (Table). The model had an excellent data fit as demonstrated by the goodness-offit statistics (Figure). Fear of crime was positively associated with depressive symptoms. Fear of crime was not directly associated with moderate or vigorous exercise. Fear of crime was directly associated with higher BMI. Depressive symptoms mediated the

Fear of crime was associated with depressive symptoms, which in turn were associated with reduced exercise and subsequently higher BMI. As in prior research,3,7 women were more likely to report fear of crime than men. The lack of a direct association between fear of crime and exercise may not be surprising. A literature review concluded that the accessibility to indoor exercise facilities was a more important predictor of physical activity than neighborhood safety.11 Future research may consider the effects of fear of crime on outdoor and indoor exercise. One limitation was the survey response rate of 25%. The results may not be generalized to all U.S. areas. Causal and temporal associations could not be assessed. People tend to overestimate their height and underestimate their weight. Depressive symptoms may not be generalized to clinical depression. The influence of neighborhood-level variables on BMI was not assessed. In prior research, neighborhood deterioration led to fear of crime, which subsequently increased depressive symptoms.7 Fear of crime may, therefore, mediate the impact of neighborhood-level variables on BMI. The findings have implications for intervention research. Many obesity interventions have focused on creating farmer’s markets, enhancing public parks, and offering fitness programs. Such programs cannot fully succeed if people’s fear of crime and subsequent depressive symptoms prevent them from engaging in exercise and outdoor activities. Community interventions should focus on the larger forces causing fear of crime. A prominent factor contributing to fear of crime is crime itself. Block-watch programs have successfully reduced crime.12 They may, however, increase fear owing to the heightened awareness of crime.

Such elevated fear is justified in areas with high crime rates. Home security improvement was an effective intervention that reduced fear in a literature review.13 Interventions to increase residents’ social capital may also be effective in targeting the pathway from fear of crime to obesity; residents who trusted that their neighbors would assist them in dangerous situations reported decreased fear of crime.14 Other obesity-prevention interventions may seek to target the depressive symptoms caused by fear of crime. Medical providers should be alert to their patients’ fear of crime in their assessments. Treating patients’ depressive symptoms may promote exercise and prevent obesity. In conclusion, future research should assess the effect of neighborhood deterioration on fear of crime, depressive symptoms, and physical activity. Community interventions may focus on reducing neighborhood deterioration and its associated fear of crime as well as on providing mental health support and safe venues for exercise.

SO WHAT? Implications for Health Promotion Practitioners and Researchers What is already known on this topic? Fear of crime leads to obesity in some but not all studies. What does this article add? In a demographically representative sample, fear of crime was associated with depressive symptoms, which in turn were associated with reduced exercise and subsequently higher body mass index. What are the implications for health promotion practice or research? Research should assess the influence of obesity-prevention strategies seeking to encourage exercise by reducing neighborhood deterioration, fear of crime, and depressive symptoms.
