“…Yet even in this covered population, reporting difficulty affording medication was associated with lower ICS use among white patients, similar to that reported elsewhere (36). However, consistent with our earlier findings, adherence did not appear to be strongly related to the amount of medication copayment (2). As uninsured adults have been shown to be nearly twice as likely to report failing to fill a prescription due to cost when compared with insured adults with prescription coverage (37), it might be expected that external factors, such as cost of medications or household income, might influence adherence to a greater extent in patients without such coverage.…”

“…Therefore, despite the large number of individuals studied, the factors associated with adherence in survey nonrespondents may have differed from those who returned their survey. This may explain why, in an earlier study not dependent on patient survey responses, we also found neighborhood factors such as crime rates to be associated with ICS adherence (2).…”

“…Inhaled corticosteroid (ICS) medication is the most consistently effective long-term control therapy for persistent asthma, yet patient adherence to ICS treatment is low (1)(2)(3)(4). Poor adherence to ICS medication is associated with increased asthmarelated emergency department visits and hospitalizations and an increased need for oral corticosteroids (1,4).…”

“…Poor adherence to ICS medication is associated with increased asthmarelated emergency department visits and hospitalizations and an increased need for oral corticosteroids (1,4). Differences in medication adherence by race-ethnicity exist and have been noted in several studies (2,(5)(6)(7)(8). This may be the result of external factors, such as income, possession of commercial health insurance (5), psychosocial stressors (e.g., residential crime rates) (2,9), and characteristics of the facility where care is provided (6).…”

Race-Ethnic Differences in Factors Associated with Inhaled Steroid Adherence Among Adults with Asthma

Rationale: Adherence to inhaled corticosteroid (ICS) medication is known to be low overall, but tends to be lower among AfricanAmerican patients when compared with white patients. Objectives: To understand the factors that contribute to ICS adherence among African-American and white adults with asthma. Methods: Eligible individuals had a prior diagnosis of asthma, one or more ICS prescriptions, and were members of a large health maintenance organization in southeast Michigan. Individuals were sent a survey that included questions about internal factors (e.g., patient beliefs, knowledge, and motivation) and external factors (e.g., socioeconomic status, barriers to care, social support, and stressors) potentially related to ICS adherence. Adherence was calculated using electronic prescription and fill data. Stepwise regression was used to identify factors associated with adherence before and after stratifying by race-ethnicity. Measurements and Main Results: Surveys were returned by 1,006 (56.3%) of 1,787 eligible patients. Adjusting for internal factors, but not external factors, diminished the relationship between raceethnicity and ICS adherence. Among African-American patients, readiness to take ICS medication was the only internal or external factor significantly associated with ICS adherence; it explained 5.6% of the variance in adherence. Among white patients, perceived ICS necessity, ICS knowledge, doctors being perceived as the source of asthma control, and readiness to take medication were the internal factors associated with ICS adherence; these accounted for 19.8% of the variance in adherence. Conclusions: Factors associated with ICS adherence appear to differ between African-American and white patients, suggesting that group-specific approaches are needed to improve adherence.

“…Previous research on crime and health has found crime to be positively related to a variety of health outcomes including selfassessed health, 37-39 physical functioning, 39 coronary heart disease, 40 adherence to inhaled glucocorticoids, 41 health-related quality of life, 42 and adverse birth events. 43 Though of growing interest, prior research is inconsistent regarding the association between crime or perceptions of crime and the likelihood of engaging in physical activity.…”

Characteristics of Mammography Facility Locations and Stage of Breast Cancer at Diagnosis in Chicago

et al. 2008

In the United States, despite substantial investment in public health initiatives to promote early detection of breast cancer through screening mammography, the proportion of female breast cancers that have advanced beyond the localized stage by the time of diagnosis remains high. Our objective in this exploratory study was to investigate whether stage of breast cancer at diagnosis among Chicago residents is associated with characteristics of the neighborhoods in which proximate mammography facilities are located. Those characteristics may influence likelihood of utilizing the service routinely and partly explain differences in stage at diagnosis. We used a retrospective cohort design and combined 3 years of data from the Illinois State Cancer Registry (ISCR) with information on locations of mammography facilities, public transportation service, crime, and area demographic and economic characteristics. Using a Geographic Information System (GIS), we identified the five facilities located nearest to each case's residence. Estimates of the association between characteristics of mammography facility locations and breast cancer stage at diagnosis were obtained using the partial proportional odds regression model. We found that the number of homicides in areas in which the nearest mammography facilities were located was associated with increased odds of later stage diagnosis. This effect was independent of age, race, and residential area education and income. We found no effect on stage of distance, public transportation service, or measures of neighborhood social similarity. The "spatial dynamics" of health may involve geographies beyond the immediate neighborhood. The results of our study suggest that areas in which the nearest mammography facilities are located may be one such geography. We hope that this study will spark research interest in the impact of health service locations on utilization.
