Abstract
Aims: The aim of the study was to describe child health in relation to housing renovations in more than 800 rental units, consisting of repairs of dilapidated kitchens and bathrooms, in the disadvantaged neighbourhood of Herrgården in Rosengård, Malmö, Sweden. Methods: Data on housing conditions and self-reported health were collected during home visits to families living in Herrgården (building renovations area) and a comparison area (neighbouring Törnrosen, with generally better housing conditions). At baseline, 130 families with 359 children participated, while 51 families with 127 children participated at follow-up. All data were collected between 2010 and 2012. Additionally, regional register data on health-care usage/in- and outpatient contacts within the public health-care system between 2008 and 2013 were also collected for all 8715 children registered as living in the two areas. Results: Self-reported health seemed to somewhat improve in both areas, with 74% versus 86% and 78% versus 88% reporting good or very good health in Herrgården and in the comparison area at baseline and follow-up, respectively. In Herrgården, crowdedness increased, while it decreased in the comparison area. The number of health-care contacts remained stable over time in Herrgården, while it decreased in the comparison area. Conclusions: Partial housing renovations did not seem to result in clear health improvements as measured with the indicators used in the present study. This could possibly be due to persisting health effects due to increased crowdedness or persisting poor housing conditions, as only kitchens and bathrooms were renovated.

Chu MT, Fenelon A, Rodriguez J, Zota AR, Adamkiewicz G. Development of a multidimensional housing and environmental quality index (HEQI): application to the American Housing Survey. Environ Health 2022; 21:56. [PMID: 35606753 PMCID: PMC9128206 DOI: 10.1186/s12940-022-00866-8] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2022] [Accepted: 05/11/2022] [Indexed: 05/27/2023]
Abstract
BACKGROUND Substandard housing conditions and hazardous indoor environmental exposures contribute to significant morbidity and mortality worldwide. Housing indices that capture the multiple dimensions of healthy housing are important for tracking conditions and identifying vulnerable households. However, most indices focus on physical deficiencies and repair costs and omit indoor environmental exposures, as few national data sources routinely collect this information. METHODS We developed a multidimensional Housing and Environmental Quality Index (HEQI) based on the World Health Organization's Housing and Health Guidelines and applied it to the 2019 American Housing Survey (AHS). The HEQI consisted of ten domains associated with poor health: household fuel combustion, dampness and mold, pests and allergens, lead paint risk, high indoor temperatures, low indoor temperatures, household crowding, injury hazards, inadequate water and sanitation, and ventilation. We evaluated the validity and performance of the HEQI against three housing characteristics (i.e., year built, monthly rent costs, unit satisfaction rating) and two established indices (i.e., Adequacy Index, Poor Quality Index). RESULTS Approximately 79% (92 million) of U.S. households reported at least one HEQI domain associated with poor health (mean per household: 1.3; range: 0,8). Prevalent domains included household fuel combustion (61.4%), dampness and mold (15.9%), inadequate water and sanitation (14.3%), and injury hazards (11.9%). Pests and allergens, low indoor temperatures, and injury hazards were consistently associated with older homes, lower rent costs, and lower unit satisfaction. Compared to established housing indices, the HEQI captured four new environmental domains which enabled the identification of 57.7 million (63%) more households with environmental risk factors like mold, cockroaches, crowding, household fuel combustion, and higher building leakage. CONCLUSIONS Indoor environmental exposures are prevalent in U.S. households and not well-captured by existing housing indices. The HEQI is a multidimensional tool that can be used to monitor indoor environmental exposures and housing quality trends in the U.S. Some domains, including radon, pesticides, asbestos, noise, and housing accessibility could not be assessed due to the lack of available data in the AHS. The mounting evidence linking residential environmental exposures with adverse health outcomes underscore the need for this data in the AHS and other national surveys.

Abstract
This article on exposome and asthma focuses on the interaction of patients and their environments in various parts of their growth, development, and stages of life. Indoor and outdoor environments play a role in pathogenesis via levels and duration of exposure, with genetic susceptibility as a crucial factor that alters the initiation and trajectory of common conditions such as asthma. Knowledge of environmental exposures globally and changes that are occurring is necessary to function effectively as medical professionals and health advocates.

A Cost-Benefit Analysis of a State-Funded Healthy Homes Program for Residents With Asthma: Findings From the New York State Healthy Neighborhoods Program. JOURNAL OF PUBLIC HEALTH MANAGEMENT AND PRACTICE 2018; 23:229-238.

Abstract
CONTEXT Despite considerable evidence that the economic and other benefits of asthma home visits far exceed their cost, few health care payers reimburse or provide coverage for these services. OBJECTIVE To evaluate the cost and savings of the asthma intervention of a state-funded healthy homes program. DESIGN Pre- versus postintervention comparisons of asthma outcomes for visits conducted during 2008-2012. SETTING The New York State Healthy Neighborhoods Program operates in select communities with a higher burden of housing-related illness and associated risk factors. PARTICIPANTS One thousand households with 550 children and 731 adults with active asthma; 791 households with 448 children and 551 adults with asthma events in the previous year. INTERVENTION The program provides home environmental assessments and low-cost interventions to address asthma trigger-promoting conditions and asthma self-management. Conditions are reassessed 3 to 6 months after the initial visit. MAIN OUTCOME MEASURES Program costs and estimated benefits from changes in asthma medication use, visits to the doctor for asthma, emergency department visits, and hospitalizations over a 12-month follow-up period. RESULTS For the asthma event group, the per person savings for all medical encounters and medications filled was $1083 per in-home asthma visit, and the average cost of the visit was $302, for a benefit to program cost ratio of 3.58 and net benefit of $781 per asthma visit. For the active asthma group, per person savings was $613 per asthma visit, with a benefit to program cost ratio of 2.03 and net benefit of $311. CONCLUSION Low-intensity, home-based, environmental interventions for people with asthma decrease the cost of health care utilization. Greater reductions are realized when services are targeted toward people with more poorly controlled asthma. While low-intensity approaches may produce more modest benefits, they may also be more feasible to implement on a large scale. Health care payers, and public payers in particular, should consider expanding coverage, at least for patients with poorly controlled asthma or who may be at risk for poor asthma control, to include services that address triggers in the home environment.

Abstract
CONTEXT Reducing exposure to environmental triggers is a critical part of asthma management. OBJECTIVE To evaluate the impact of a healthy homes intervention on asthma outcomes and assess the impact of different targeting strategies. SETTING The New York State (NYS) Healthy Neighborhoods Program (HNP) operates in select communities with a higher burden of housing-related illness and associated risk factors. PARTICIPANTS Residents with asthma were recruited through 3 mechanisms: door-to-door canvassing (CANVASSED), 752 residents in 457 dwellings; referrals from community partners (REFERRED), 573 residents in 307 dwellings; referrals of Medicaid enrollees with poorly controlled asthma (TARGETED), 140 residents in 140 dwellings. INTERVENTION The NYS HNP provides visual assessments and low-cost interventions to identify and address asthma triggers and trigger-promoting conditions in the home environment. Conditions are reassessed during a revisit conducted 3 to 6 months after the initial visit. MAIN OUTCOME MEASURE(S) The analysis compares improvements across the 3 groups for measures of asthma self-management, health care access, morbidity, and environmental conditions. An asthma trigger score characterizing the extent of multiple triggers in a dwelling was also calculated. RESULTS Among 1465 adults and children, there were significant improvements in environmental conditions and self-reported self-management, health care access, and asthma morbidity outcomes for each group. The improvement was greatest in the TARGETED group for most outcomes, but selected measures of self-management and health care access were greater in the other groups. The mean improvement was significantly greater in the TARGETED group. CONCLUSION Targeting the intervention to people with poorly controlled asthma maximizes improvements in trigger avoidance and asthma morbidity; however, other recruitment strategies are effective for impacting endpoints related to health care access and self-management. This evaluation demonstrates that a low-intensity home-based environmental intervention is effective as well as practical and feasible. Health care payers, state and local health departments, and others should consider investing in these home-based services as part of a comprehensive asthma care package.

Abstract
Identifying asthma triggers forms the basis of environmental secondary prevention. These triggers may be allergenic or nonallergenic. Allergenic triggers include indoor allergens, such as house dust mites (HDMs), molds, pets, cockroaches, and rodents, and outdoor allergens, such as pollens and molds. Clinical observations provide support for the role of HDM exposure as a trigger, although avoidance studies provide conflicting results. Molds and their metabolic products are now considered to be triggers of asthma attacks. Pets, dogs, and especially cats can undoubtedly trigger asthmatic symptoms in sensitized subjects. Avoidance is difficult and rarely adhered to by families. Cockroach allergens contribute to asthma morbidity, and avoidance strategies can lead to clinical benefit. Mouse allergens are mostly found in inner-city dwellings, but their implication in asthma morbidity is debated. In the outdoors, pollens can induce seasonal asthma in sensitized individuals. Avoidance relies on preventing pollens from getting into the house and on minimizing seasonal outdoor exposure. Outdoor molds may lead to severe asthma exacerbations. Nonallergenic triggers include viral infections, active and passive smoking, meteorological changes, occupational exposures, and other triggers that are less commonly involved. Viral infection is the main asthma trigger in children. Active smoking is associated with higher asthma morbidity, and smoking cessation interventions should be personalized. Passive smoking is also a risk factor for asthma exacerbation. The implementation of public smoking bans has led to a reduction in the hospitalization of asthmatic children. Air pollution levels have been linked with asthmatic symptoms, a decrease in lung function, and increased emergency room visits and hospitalizations. Since avoidance is not easy to achieve, clean air policies remain the most effective strategy. Indoor air is also affected by air pollutants, such as cigarette smoke and volatile organic compounds generated by building and cleaning materials. Occupational exposures include work-exacerbated asthma and work-related asthma.

Abstract
Previous research has found evidence of an association between indoor air pollution and asthma morbidity in children. Environmental intervention studies have been performed to examine the role of household environmental interventions in altering indoor air pollution concentrations and improving health. Previous environmental intervention studies have found only modest effects on health outcomes and it is unclear if the health benefits provided by environmental modification are comparable with those provided by medication. Traditionally, the statistical analysis of environmental intervention studies has involved performing two intention-to-treat analyses that separately estimate the effect of the environmental intervention on health and the effect of the environmental intervention on indoor air pollution concentrations. We propose a principal stratification approach to examine the extent to which an environmental intervention's effect on health outcomes coincides with its effect on indoor air pollution. We apply this approach to data from a randomized air cleaner intervention trial conducted in a population of asthmatic children living in Baltimore, Maryland, USA. We find that among children for whom the air cleaner reduced indoor particulate matter concentrations, the intervention resulted in a meaningful improvement of asthma symptoms with an effect generally larger than previous studies have shown. A key benefit of using principal stratification in environmental intervention studies is that it allows investigators to estimate causal effects of the intervention for sub-groups defined by changes in the indoor air pollution concentration.

Abstract
PURPOSE The aim of the study was to determine the effect of Orem's self-care model on the self-care of adolescents with asthma. DESIGN AND METHODS In this experimental design, adolescents with asthma (N = 80) received home visits and individualized care based on theory-guided nursing diagnoses. Patients in the experimental group were visited in their homes eight times, and those in the control group were visited two times. RESULTS The five self-care skills of medicine usage, peak expiratory flow meter usage, applying an asthma action plan, keeping a daily follow-up schedule, and protecting against triggering factors differed significantly between the first and last visits in the experimental group, whereas the self-care skills of adolescents in the control group did not change. PRACTICE IMPLICATIONS Applying Orem's self-care model increased the self-care skills of adolescents with asthma.

Abstract
Parents of children who attend Head Start Centers are key participants in the health promotion and care of their own children. This non-randomized, longitudinal study aimed to test the effectiveness of an educational intervention based on the asthma and healthy homes curriculum targeting parents of Head Start children with or without an asthma diagnosis. One hundred and fifteen parents of children in Head Start Centers received an educational intervention at their corresponding sites, additionally pre- and post-test surveys were administered to measure educational intervention outcomes. A follow-up survey was conducted 6 months after the educational intervention was offered. Results showed a statistically significant increase in asthma and healthy home-knowledge (p < 0.001) in several areas. At 6 months post-intervention (54.4 %) (61 participants) were contacted and 98.4 % of made changes in their households as a result of their training. This study suggests that education can improve knowledge and change behaviors for the well-being of the residents of that household.

Abstract
OBJECTIVES Comorbidities complicate our understanding of childhood asthma and its risk factors. This study examined the relationships between asthma, self-reported burden of disease symptoms and residential hazards in a representative sample of households in Saginaw, Michigan. STUDY DESIGN A population-based cross-sectional survey. METHOD The study involved 643 households randomly selected from the City of Saginaw (Michigan) with children 12 years of age or younger or pregnant woman. The survey was completed using random digit dialing, Computer-Assisted Telephone Interviewing (CATI) method. The audit instrument for residential hazards developed for the study was used to gather information on 71 household hazards organized in eight scales (dimensions): structural scale, moisture/mold scale, electrical scale, ventilation and combustion appliances scale, pest scale, pets scale, fire scale, and lifestyle-associated factors scale. The data were used to calculate an aggregate score of the household hazard index (HHI) for each housing unit. We also collected information on 43 symptoms of diseases likely to be associated with exposure to residential hazards as well as the demographic characteristics for each household. RESULTS Asthma prevalence rate among the 1206 children was 18.9% with 27.7% of households reporting at least one asthmatic child. The prevalence of health hazards in households of Saginaw was pervasively high with the rate for each of 29 hazards being over 30%. The HHI was found to be a good predictor of health outcomes in homes; the following linear regression equation describes the relationship between childhood asthma and the scores for individual scales of HHI: Number of Asthmatic Children=0.009(Structural)+0.004(Mold) +0 .019(Pests)-0.023(Pets)-0.029(Fire); (r(2)=0.054; p-value<0.001). Children who were living in housing units classified as high risk (top 25% of the HHI score) were found to be disproportionately afflicted with asthma, allergic reaction and burden of symptoms compared to children who lived in low-risk homes. Average number of symptoms in the households was 14±10 and the top 25% of the households had over 26 symptoms. Asthma was associated (comorbid) with each of the 40 symptoms (out of the 43) in the inventory scale, and the HHI was found to be a good predictor of the symptom burden (total count of symptoms) in participating households. CONCLUSIONS Recognition of the large extent of comorbidity in asthmatic children has implications for the way in which this disease should be treated or managed. In addition, the study of comorbidity between asthma and related risk factors may be important in understanding complex exposure-disease relationships which could lead to more effective interventions.

Abstract
OBJECTIVES This study investigated the validity and responsiveness of a rating scale designed to assess the housing-based hazards and their relationships to burden of disease symptoms in the building occupants. STUDY DESIGN A population-based cross-sectional survey. METHODS Random-digit dialing with computer-assisted phone interviews was conducted to obtain information from 642 households in the City of Saginaw, Michigan about 71 housing-based hazards, symptoms of 43 diseases often associated with environmental exposures and demographic characteristics. The housing-based hazard index (HHI) was calculated from scores of hazards across the following eight dimensions: structural scale (18 items); moisture/mold scale (8 items), electrical scale (7 items), ventilation and combustion appliances scale (6 items); pest scale (6 items); pets scale (4 items), fire scale (6 items) and lifestyle-associated factors scale (12 items). Each item was assigned a relative score based on the likelihood that the housing occupants would be exposed to the hazard, the potential for serious health impacts, and the reported strength of its association with childhood lead poisoning and respiratory diseases. The psychometric properties of HHI and individual domains (scales) were assessed along with the associations between these indicators and the inventory of disease symptoms. RESULTS The reliability of HHI was demonstrated by assessments of its dimensionality and internal consistency. Analysis of the predictive validity and responsiveness indicates that HHI and scores for most of the individual scales can discriminate between households in relation to the burden of reported disease symptoms. CONCLUSIONS The HHI represents a valid, reasonably reliable, and parsimonious measure of hazards that are congruent with the burden of symptoms generally associated with housing-related diseases.

Effectiveness of home-based, multi-trigger, multicomponent interventions with an environmental focus for reducing asthma morbidity: a community guide systematic review. Am J Prev Med 2011; 41:S5-32.

Abstract
CONTEXT Asthma exacerbations are commonly triggered by exposure to allergens and irritants within the home. The purpose of this review was to evaluate evidence that interventions that target reducing these triggers through home visits may be beneficial in improving asthma outcomes. The interventions involve home visits by trained personnel to conduct two or more components that address asthma triggers in the home. Intervention components focus on reducing exposures to a range of asthma triggers (allergens and irritants) through environmental assessment, education, and remediation. EVIDENCE ACQUISITION Using methods previously developed for the Guide to Community Preventive Services, a systematic review was conducted to evaluate the evidence on effectiveness of home-based, multi-trigger, multicomponent interventions with an environmental focus to improve asthma-related morbidity outcomes. The literature search identified over 10,800 citations. Of these, 23 studies met intervention and quality criteria for inclusion in the final analysis. EVIDENCE SYNTHESIS In the 20 studies targeting children and adolescents, the number of days with asthma symptoms (symptom-days) was reduced by 0.8 days per 2 weeks, which is equivalent to 21.0 symptom-days per year (range of values: reduction of 0.6 to 2.3 days per year); school days missed were reduced by 12.3 days per year (range of values: reduction of 3.4 to 31.2 days per year); and the number of asthma acute care visits were reduced by 0.57 visits per year (interquartile interval: reduction of 0.33 to 1.71 visits per year). Only three studies reported outcomes among adults with asthma, finding inconsistent results. CONCLUSIONS Home-based, multi-trigger, multicomponent interventions with an environmental focus are effective in improving overall quality of life and productivity in children and adolescents with asthma. The effectiveness of these interventions in adults is inconclusive due to the small number of studies and inconsistent results. Additional studies are needed to (1) evaluate the effectiveness of these interventions in adults and (2) determine the individual contributions of the various intervention components.

Abstract
Environmental conditions within the home can exacerbate asthmatic children's symptoms. To improve health outcomes among this group, we implemented an in-home environmental public health program-Healthy Homes University--for low-income families in Lansing, Michigan, from 2005 to 2008. Families received four visits during a six-month intervention. Program staff assessed homes for asthma triggers and subsequently provided products and services to reduce exposures to cockroaches, dust mites, mold, tobacco smoke, and other triggers. We also provided asthma education that included identification of asthma triggers and instructions on specific behaviors to reduce exposures. Based on self-reported data collected from 243 caregivers at baseline and six months, the impact of asthma on these children was substantially reduced, and the proportion who sought acute unscheduled health care for their asthma decreased by more than 47%.

Abstract
UNLABELLED We examined home safety hazards, comparing renter- to owner-occupied housing among urban, immigrant Mexican families. METHODS Interviews and home inspections were conducted among urban, Spanish-speaking immigrant families with children. We estimated weighted hazard prevalence and used logistic regression to compare owner- and renter-occupied homes. Of 313 eligible households, 250 (80%) enrolled. Respondents were predominantly Mexican-born (99%), low income (72.6%) and lower education (92.3%). Most homes had fire, burn, fall, poisoning, electrocution and fire escape hazards, including high tap water temperatures (76.4%; 95% CI: 69.0, 83.7%), no working smoke alarms (60.0%; 51.3, 68.8%), slippery bathtub/shower surfaces (58.7%; 49.9, 67.5%), blocked fire escape routes (55.9%; 47.2, 64.5%) and child-accessible medications (71.0%; 60.1, 81.3%). After adjustment for sociodemographics, fire escape (OR = 8.8; 95% CI: 2.8, 27.7), carbon monoxide poisoning (OR = 2.9; 1.4, 6.2) and drowning (OR = 3.5; 1.3, 9.4) hazards were more likely in owner- than renter-occupied homes. Housing age and type explained most differences. Many urban, immigrant Spanish-speaking families live in unsafe homes. For this population, housing safety programs should be targeted based on housing age and type rather than tenure.

Abstract
BACKGROUND Injury in the home is common, accounting for approximately a third of all injuries. The majority of injuries to children under five and people aged 75 and older occur at home. Multifactorial injury prevention interventions have been shown to reduce injuries in the home. However, few studies have focused specifically on the impact of physical adaptations to the home environment and the effectiveness of such interventions needs to be ascertained. OBJECTIVES To determine the effect of modifications to the home environment on the reduction of injuries due to environmental hazards. SEARCH STRATEGY We searched The Cochrane Library, MEDLINE, EMBASE and other specialised databases. We also scanned conference proceedings and reference lists. We contacted the first author of all included randomised controlled trials. The searches were last updated to the end of December 2009, and were not restricted by language or publication status. SELECTION CRITERIA Randomised controlled trials. DATA COLLECTION AND ANALYSIS Two authors screened all abstracts for relevance, outcome and design. Two authors independently assessed methodological quality and extracted data from each eligible study. We performed meta-analysis to combine effect measures, using a random-effects model. We assessed heterogeneity using an I(2) statistic and a Chi(2) test. MAIN RESULTS We found 28 published studies and one unpublished study. Only two studies were sufficiently similar to allow pooling of data for statistical analyses. Studies were divided into three groups; children, older people and the general population/mixed age group. None of the studies focusing on children or older people demonstrated a reduction in injuries that were a direct result of environmental modification in the home. One study in older people demonstrated a reduction in falls and one a reduction in falls and injurious falls that may have been due to hazard reduction. One meta-analysis was performed which examined the effects on falls of multifactorial interventions consisting of home hazard assessment and modification, medication review, health and bone assessment and exercise (RR 1.09, 95% CI 0.97 to 1.23). AUTHORS' CONCLUSIONS There is insufficient evidence to determine whether interventions focused on modifying environmental home hazards reduce injuries. Further interventions to reduce hazards in the home should be evaluated by adequately designed randomised controlled trials measuring injury outcomes. Recruitment of large study samples to measure effect must be a major consideration for future trials. Researchers should also consider using factorial designs to allow the evaluation of individual components of multifactorial interventions.

Abstract
This study explores the efficacy of an environmental health intervention in several poor colonias in Ciudad Juárez (Mexico). Parents of children with respiratory problems were given environment-friendly products intended to replace hazardous products used in the home, as well as information about environmental health. Parents were surveyed before and after to measure the effectiveness of the intervention and to gauge perceptions. There was a significant reduction in hazardous chemical use (eg, cleaning products and pesticides) and breathing problems. While the intervention focused on changing in-home behaviors, open-ended responses revealed that parents were most concerned about outdoor environmental conditions over which they had less control.

Abstract
BACKGROUND Injury in the home is extremely common, accounting for around a third of all injuries. The majority of injuries of children under five and people aged 75 and over, occur at home. Multifactorial injury prevention interventions have been shown to reduce injuries in the home. However, few studies have focused specifically on the impact of physical adaptations to the home environment and the effectiveness of such interventions needs to be ascertained. OBJECTIVES To review the evidence for the effect on injuries of modification of the home environment with a primary focus on interventions to reduce physical hazards. SEARCH STRATEGY We searched The Cochrane Library, MEDLINE, EMBASE, National Research Register and other specialised databases. We also scanned conference proceedings and reference lists. In addition, we contacted experts and trialists in the field. The searches were not restricted by language or publication status. The searches were last updated in December 2004. SELECTION CRITERIA Randomised controlled trials. DATA COLLECTION AND ANALYSIS All abstracts were screened by two authors for relevance, outcome and design. Two authors independently assessed methodological quality and extracted data from each eligible study. MAIN RESULTS We found 18 published and one unpublished trials. Trials were not sufficiently similar to allow pooling of data by statistical analyses, so this review takes a narrative form. Studies were divided into three groups based on the primary population sample; children (five studies), older people (14 studies) and the general population/mixed age group (no studies). None of the studies focusing on children demonstrated a reduction in injuries that might have been due to environmental adaptation in the home; one study reported a reduction in injuries and in hazards but the two could not be linked. Of the 14 included studies in older people, none demonstrated a reduction in injuries due to hazard reduction, although two demonstrated a reduction in falls that could be due to hazard reduction. AUTHORS' CONCLUSIONS There is insufficient evidence to determine the effects of interventions to modify environmental home hazards. Further interventions to reduce hazards in the home should be evaluated by adequately designed randomised controlled trials measuring injury outcomes. Recruitment of large study samples to measure effect must be a major consideration for future trials.
