Association Between Rental Assistance Programs and Hemoglobin A1c Levels Among US Adults

Examining Health Differences Among Older Adults with Federal Rental Assistance in the United States

About 1.8 million older adults receive rental assistance in the United States, but surprisingly little is known about their health, especially among the growing number of older housing choice voucher (HCV) holders. This is the first known study to use nationally representative data (2006-2018) from the National Health Interview Survey merged with Department of Housing and Urban Development (HUD) administrative data to describe the health of older HUD renters (N = 4,582) living in public housing, multifamily housing, or receiving an HCV. Logistic regression models were used to examine potential health differences by HUD program type. Contrary to expectations, the results suggest that older HCV holders were more likely to experience health challenges compared to older adults with project-based assistance. The results bring awareness to the health challenges experienced by older HCV holders and emphasize the need for future research to examine why older HCV holders are more likely to experience these health challenges. Policy makers and program administrators must consider how the HCV program has significantly aged in the past two decades and consider what program and policy changes are necessary to ensure that older adults have access to affordable housing that matches their changing needs and preferences.

Association Between Rental Assistance Programs and Undiagnosed Diabetes Among U.S

BACKGROUND

Rental assistance programs have been linked to better housing quality, stability, healthcare access, and reduced likelihood of uncontrolled diabetes. However, its direct association with diabetes screening is uncertain.

OBJECTIVE

To determine whether federal rental assistance programs are associated with lower odds of undiagnosed diabetes.

DESIGN

We used a quasi-experimental approach, comparing outcomes among adults receiving rental assistance to those who entered assisted housing within 2 years after their health data were collected. We test the a priori hypothesis that rental assistance will be associated with decreased odds of undiagnosed diabetes.

PARTICIPANTS

Participants in the National Health and Nutrition Examination Survey 1999-2018 who received rental assistance and who had diabetes.

INTERVENTION

Current rental assistance participation, including specific housing programs.

MAIN MEASURES

Undiagnosed diabetes based on having hemoglobin A1c ≥ 6.5% but answering no to the survey question of being diagnosed with diabetes.

KEY RESULTS

Among 435 eligible adults (median age 54.5 years, female 68.5%, non-Hispanic white 32.5%), 80.7% were receiving rental assistance programs at the time of the interview, and 19.3% went on to receive rental assistance within 2 years. The rates of undiagnosed diabetes were 15.0% and 25.3% among those receiving rental assistance programs vs. those in the future assistance group (p-value = 0.07). In an adjusted logistic regression model, adults receiving rental assistance had lower odds of undiagnosed diabetes (OR 0.52, 95% CI 0.28-0.94) than those in future assistance groups. Sex, race and ethnic group, educational level, and poverty ratio were not significantly associated with having undiagnosed diabetes, but individuals aged 45-64 years had significantly lower odds of undiagnosed diabetes (OR 0.21, 95% CI 0.08-0.53) compared with those aged 18-44.

CONCLUSIONS

Rental assistance was linked to lower odds of undiagnosed diabetes, suggesting that affordable housing programs can aid in early recognition and diagnosis, which may improve long-term outcomes.

Federal Housing Assistance and Blood Lead Levels in a Nationally Representative US Sample Age 6 and Older: NHANES, 1999-2018

BACKGROUND

Federal housing assistance is an important policy tool to ensure housing security for low-income households. Less is known about its impact on residential environmental exposures, particularly lead.

OBJECTIVES

We conducted a quasi-experimental study to investigate the association between federal housing assistance and blood lead levels (BLLs) in a nationally representative US sample age 6 y and older eligible for housing assistance.

METHODS

We used the 1999-2018 National Health and Nutrition Examination Survey (NHANES) linked with US Department of Housing and Urban Development (HUD) administrative records to assess BLLs of NHANES participants with concurrent HUD housing assistance (i.e., current recipients, n = 3 , 0 71 ) and those receiving assistance within 2 y after the survey (i.e., pseudo-waitlist recipients, n = 1,235 ). We estimated BLL least squares geometric means (LSGMs), odds ratio (OR) for BLL ≥ 3.5 μ g / dL , and percent differences in LSGMs by HUD housing assistance status adjusting for age, sex, family income-to-poverty ratio, education, country of birth, race/ethnicity, region, and survey year. We also examined effect modification using interaction terms and stratified analyses by program type [i.e., public housing, multifamily, housing choice vouchers (HCV)], and race/ethnicity.

RESULTS

Current HUD recipients had a significantly lower LSGM [1.07 μ g / dL ; 95% confidence interval (CI): 1.02, 1.12] than pseudo-waitlist recipients (1.21   μ g / dL ; 95% CI: 1.14, 1.28), with an adjusted OR of 0.60 (95% CI: 0.42, 0.87) for BLL ≥ 3.5 μ g / dL . Some effect modification were observed: The protective association of HUD assistance on BLL was strongest among public housing (- 19.5 % LSGM; 95% CI: - 27.5 % , - 1 0 . 7 % ), multifamily (- 12.5 % LSGM; 95% CI: - 2 0 . 7 % , - 3.5 % ), and non-Hispanic White (- 2 0 . 6 % LSGM; 95% CI: - 29.8 % , - 1 0 . 3 % ) recipients. It was weaker to null among HCV (- 5.7 % LSGM; 95% CI: - 12.7 , 1.7%), non-Hispanic Black (- 1.6 % LSGM; 95% CI: - 8.1 % , 5.4%), and Mexican American (-12.5% LSGM; 95% CI: - 31.9 % , 12.5 % ) recipients.

DISCUSSION

Our research underscores the importance of social-structural determinants like federal housing assistance in providing affordable, stable, and healthy housing to very low-income households. More attention is needed to ensure housing quality and racial equity across HUD's three major housing assistance programs. https://doi.org/10.1289/EHP12645.

Exposing Pittsburgh Landlords To Asset-Framing Narratives: An Experiment To Increase Housing Voucher Participation

Landlords are essential actors within the rental housing market, and there is much to be learned about their willingness to participate in rental assistance programs that improve access to stable housing. Because the success of these programs, such as the Mobility (Location-Based) Voucher program in Pittsburgh, Pennsylvania, can be derailed by landlord opposition, it is important to test strategies that increase landlords' participation. Using data from a unique survey of Pittsburgh landlords, we found that exposing landlords to an asset-framing narrative that highlighted the social, economic, and health benefits of receiving a mobility voucher increased landlords' reported willingness to rent to a mobility voucher recipient by 21 percentage points. Reported willingness was also higher among landlords who believed that housing affordability was connected to health. Our findings offer insight into how to increase landlords' participation in affordable housing programs that require their engagement to succeed.

Federal Housing Assistance and Chronic Disease Among US Adults, 2005-2018

Introduction

Housing insecurity is associated with poor health outcomes. Characterization of chronic disease outcomes among adults with and without housing assistance would enable housing programs to better understand their population's health care needs.

Methods

We used National Health and Nutrition Examination Survey (NHANES) data from 2005 through 2018 linked to US Department of Housing and Urban Development (HUD) administrative records to estimate the prevalence of obesity, diabetes, and hypertension and to assess the independent associations between housing assistance and chronic conditions among adults receiving HUD assistance and HUD-assistance-eligible adults not receiving HUD assistance at the time of their NHANES examination. We estimated propensity scores to adjust for potential confounders among linkage-eligible adults who had an income-to-poverty ratio less than 2 and were not receiving HUD assistance. Sensitivity analysis used 2013-2018 NHANES cycles to account for disability status.

Results

Adults not receiving HUD assistance had a significantly lower adjusted prevalence of obesity (42.1%; 95% CI, 40.4%-43.8%) compared with adults receiving HUD assistance (47.5%; 95% CI, 44.8%-50.3%), but we found no differences for diabetes and hypertension. We found significant associations between housing assistance and obesity (adjusted odds ratio = 1.29; 95% CI, 1.12-1.47), but these were not significant in the sensitivity analysis with and without controlling for disability status. We found no significant associations between housing assistance and diabetes or hypertension.

Conclusion

Based on data from a cross-sectional survey, we observed a higher prevalence of obesity among adults with HUD assistance compared with HUD-assistance-eligible adults without HUD assistance. Results from this study can help inform research on understanding the prevalence of chronic disease among adults with HUD assistance.

Housing instability and cardiometabolic health in the United States: a narrative review of the literature

Housing instability is variably defined but generally encompasses difficulty paying rent, living in poor or overcrowded conditions, moving frequently, or spending the majority of household income on housing costs. While there is strong evidence that people experiencing homelessness (i.e., lack of regular housing) are at increased risk for cardiovascular disease, obesity, and diabetes, less is known about housing instability and health. We synthesized evidence from 42 original research studies conducted in the United States examining the association of housing instability and cardiometabolic health conditions of overweight/obesity, hypertension, diabetes, and cardiovascular disease. The included studies varied widely in their definitions and methods of measuring housing instability, but all exposure variables were related to housing cost burden, frequency of moves, living in poor or overcrowded conditions, or experiencing eviction or foreclosure, measured at either the individual household level or at a population level. We also included studies examining the impact of receipt of government rental assistance, which serves as a marker of housing instability given that its purpose is to provide affordable housing for low-income households. Overall, we found mixed but generally adverse associations between housing instability and cardiometabolic health, including higher prevalence of overweight/obesity, hypertension, diabetes, and cardiovascular disease; worse hypertension and diabetes control; and higher acute health care utilization among those with diabetes and cardiovascular disease. We propose a conceptual framework for pathways linking housing instability and cardiometabolic disease that could be targeted in future research and housing policies or programs.

Rental assistance improves food security and nutrition: An analysis of National Survey Data

The U.S. is experiencing a severe housing affordability crisis, resulting in households having to make difficult trade-offs between paying for a place to live and basic health necessities such as food. Rental assistance may mitigate these strains, improving food security and nutrition. However, only one in five eligible individuals receive assistance, with an average wait time of two years. Existing waitlists create a comparable control group, allowing us to examine the causal impact of improved housing access on health and well-being. This national quasi-experimental study utilizes linked NHANES-HUD data (1999-2016) to investigate the impacts of rental assistance on food security and nutrition using cross-sectional regression. Tenants with project-based assistance were less likely to experience food insecurity (B = -0.18, p = 0.02) and rent-assisted individuals consumed 0.23 more cups of daily fruits and vegetables compared the pseudo-waitlist group. These findings suggest that the current unmet need for rental assistance and resulting long waitlists have adverse health implications, including decreased food security and fruit and vegetable consumption.
