About this trial
This project will compare the health effects of public housing renovation, neighborhood built and social environment improvements, and indoor air purification, alone and in combination, as well as the cost effectiveness of each approach.
STUDY 1: The study will assess the effects of public housing and neighborhood environment (built and social) improvements on health-related behaviors, psychosocial and physiologic stress, and self-reported and physiological markers of lung health and chronic disease.
STUDY 2: The study will determine whether indoor air purification can positively impact lung health in public housing sites not undergoing housing renovation, comparing a site near industrial pollution vs one less contaminated.

Treatments tested in this trial
Indoor Air Purification
Other interventionAn indoor air purifier with a dual HEPA/activated carbon filter, a usage tracker, and an indoor air quality monitor will be installed in public housing residences.
Neighborhood Improvements
Other interventionImproved built environment (green space, sidewalks, street lights) and social environment (educational and workforce development programs, wrap-around social services, Internet access).
Housing Improvements
Other interventionHigh-quality public housing
Treatment groups
Trial outcomes
Primary outcomes
Change in Patient-Reported Outcomes Measurement Information System (PROMIS-10) Global Health
A self-reported measure of physical, mental, and social health. 10 item questionnaire T-score metric from zero to 100 where higher T-scores indicate better health.
Change in Allostatic load
Measure of cumulative stress burden as the number of 10 indicators above a threshold: (1) serum albumin \<3.8 g/dL, (2) C Reactive Protein (CRP) \>3 mg/L, (3) High-Density Lipoprotein (HDL) \<40 mg/dL, (4) total cholesterol ≥240 mg/dL, (5) heart rate ≥90 beats/min, (6) systolic Blood Pressure (BP) ≥140 mmHg, (7) diastolic BP ≥90 mmHg, (8) serum creatinine ≥1.3 mg/dL, (9) Blood Urea Nitrogen (BUN) ≥18 mg/dL, and (10) waist circumference \>88 cm in women, \>102 cm in men.
Change in Indoor Air Quality
Particulate matter (PM2.5). Measures particles in the air that are 2.5 micrometers or smaller in diameter.
Secondary outcomes
The percentage change in FEV1/FVC
FEV1/FVC. A measure of lung funtion that compares the amount of air exhaled in the first second (FEV1) to the total amount of air exhaled in a forced breath (FVC).
