Housing environments and child health conditions among recent Mexican immigrant families: a population-based study

Housing inequalities and health outcomes among migrant and refugee populations in high-income countries: a mixed-methods systematic review

BACKGROUND

Migrant and refugee populations are disproportionately affected by the housing crises reportedly impacting high-income countries around the globe. However, the health implications of housing inequalities within these communities and contexts remain relatively understudied. This review aimed to synthesise the evidence on housing and health inequalities prevalent among migrant and refugee populations in high-income countries, and to identify the pathways linking housing inequalities and health outcomes.

METHODS

This systematic review employed the Joanna Briggs Institute (JBI) methodology for mixed-methods systematic reviews using a convergent integrated approach to synthesis and integration. Electronic database searches were conducted using Medline (OVID), Web of Science (ISI), Embase (OVID), PsycInfo (OVID), Scopus, and CINAHL (EBSCO), supplemented by grey literature searches on Google Scholar, MedNar, and WHOLIS. Eligible studies included quantitative, qualitative, and mixed methods designs focused on understanding how housing inequalities are associated with physical and mental health outcomes.

RESULTS

A total of 65 studies published between 1995 and 2024 were included in this review, comprising 38 quantitative and 27 qualitative studies. Substandard housing conditions, such as overcrowding and poor ventilation, were consistently associated with adverse physical and mental health outcomes, including respiratory illnesses and experiences of anxiety and depression. The type of housing tenure also impacted both physical and mental health, specifically living in inadequate rental housing as opposed to self-owned homes, was linked with poorer physical health and increased risk of mental health issues. Similarly, housing insecurity stemming from unstable housing situations and insecure tenancy, as well as neighbourhood conditions such as safety concerns and living in deprived neighbourhoods, led to the exacerbation of both physical and mental health issues. Furthermore, housing affordability challenges and decreased housing satisfaction were linked with poor mental health outcomes such as experiences of depression and psychological distress.

CONCLUSIONS

This review highlights the critical role of housing as a social determinant of health and wellbeing for migrant and refugee populations in high-income countries, along with highlighting the potential pathways through which housing inequalities impact physical and mental health outcomes. Ensuring access to adequate, affordable, and secure housing, while also improving neighbourhood conditions, is essential for improving the health and wellbeing of migrant and refugee populations.

How Does Social Inequality Alter Relationships Between Porous Cranial Lesions and Mortality? Examining the Relationship Between Skeletal Indicators of Stress, Socioeconomic Status, and Survivorship in a Pediatric Autopsy Sample

BACKGROUND

In prior exploration of modern and archeological populations, lower SES has been associated with an increased risk of mortality. However, SES is often difficult to ascertain in archeological populations. Thus, explorations of skeletal lesions and their association with mortality may be subject to confounding factors that alter the strength and/or direction of this association.

METHODS

The present study uses data from a modern, documented coronial pediatric dataset to examine the association between porous cranial lesions (PCLs) (cribra orbitalia [CO] and porotic hyperostosis [PH]) and age at death while controlling for SES, as inferred through housing type, with manufactured or apartment housing identified as reflecting individuals from lower SES backgrounds in this context. We include 887 (535 males, 352 females) individuals aged 0.5-20.9 years from New Mexico who died between 2011 and 2022. Kaplan-Meier survival analysis was used to assess survivorship as related to PCLs and SES.

RESULTS

Low SES is associated with lower survivorship. CO does not have a significant association with age at death when not controlling for SES; PH alone is associated with older age at death. Disadvantaged individuals with PCLs have significantly reduced survivorship than those with higher SES.

DISCUSSION AND CONCLUSIONS

The findings of this study demonstrate that low SES results in reduced survivorship, and those with low SES and PCLs have worse survivorship than less disadvantaged individuals with PCLs. Thus, the strong contribution of SES to mortality necessitates the consideration of the sociocultural context as a confounding factor when examining associations between variables of interest (such as lesions) and mortality in both past and present populations.

Atopic Dermatitis: The Role of the Social Determinants of Health on Severity and Access to Care

Atopic dermatitis (AD) is a multi-system inflammatory skin disorder with early onset in the skin. It is well known that Black and Hispanic children in the United States experience specific barriers in regards to accessing care for AD, including greater severity on presentation and more need for care including increased usage of emergency services. Understanding these social determinants is vital if social change is to be made and if policies are to be constructed to create enduring reductions in disparity in a meaningful way that can potentially level disease severity and access to care for all segments of the family.

Overcrowding and Hazardous Dwelling Condition Characteristics: A Systematic Search and Scoping Review of Relevance for Health

Crowding in dwellings is an important public health issue. We hypothesize that overcrowding may cause indirect health effects by adversely affecting the dwelling itself, for example, by increasing dampness leading to mold. We therefore performed a systematic search and a scoping review on overcrowding leading to dwelling condition characteristics of relevance for health. A literature search was performed using the PubMed and Scopus databases up to 5 March 2021. The search yielded 100 records with relevant information. We found that overcrowding is defined in numerous ways and often address "socially deprived" populations. Six studies report associations of overcrowding with at least one dwelling condition characteristic, namely lead, cadmium, microorganism distribution, dust mite and cockroach allergens in dust, cockroach infestation, peeling paint, and mold. One of the studies reports associations between several characteristics, e.g., association of mold with cleanliness and rodent infestation, and points out the common use of pesticides. Additional characteristics were extracted from the remaining 94 records, without data on statistical associations with overcrowding. Our review suggests that multiple potentially hazardous dwelling condition characteristics often coincide in overcrowded dwellings. The epidemiological attribution of health effects to any characteristic is therefore difficult. Causal relationships are even more difficult to establish, as overcrowding is also associated with a range of social and other circumstances that may affect health. The complexity should be considered by scientists and practitioners dealing with overcrowding in dwellings.

Association between parental autoimmune disease and atopic dermatitis in their offspring: a matched case-control study

BACKGROUND

Atopic dermatitis (AD) is associated with many autoimmune diseases, in part due to overlapping genetic risk loci. While parental atopic disease is an important risk for AD in the offspring, little is known on the putative associations between parental autoimmune disease and AD in their children.

MATERIALS AND METHODS

All children born between 1996 and 2011 who received a diagnosis of AD in the hospital system before their fifth birthday were matched 1 : 10 with children from the general population. Maternal and paternal autoimmune diseases were assessed using registry-based data. Conditional logistic regression was performed on the relationships between parental autoimmune diseases and AD in their children.

RESULTS

A total of 8589 children with AD were matched with controls. One or more autoimmune disease was identified in 5.89% (506/8589) of mothers to AD children and 3.67% (315/8589) of fathers to AD children compared to 4.85% (4163/85 890) and 3.28% (2816/85 890) in parents of control children. Maternal autoimmune disease but not paternal autoimmune disease was associated with AD in the offspring (odds ratio [OR] 1.20 [95% confidence interval (CI) 1.20-1.32] and OR 1.08 [0.96-1.22], respectively), Two or more maternal autoimmune diseases, maternal dermatologic autoimmune disease and maternal digestive autoimmune disease were all also associated with AD development in her children (1.96 [95% CI 1.36-2.84], OR 1.60 [95% CI 1.24-2.07] and OR 1.24 [95% CI 1.06-1.45], respectively).

CONCLUSIONS

The risk of AD is influenced by many factors including atopy status and filaggrin gene mutations. In this matched case-control study, maternal autoimmune disease was associated with AD diagnosis in the offspring. Maternal dermatologic and digestive autoimmune diseases were most closely associated with subsequent AD diagnosis in the offspring.

High burden of atopy in immigrant families in substandard apartments in Sweden - on the contribution of bad housing to poor health in vulnerable populations

Background

Atopic disorders are a global concern. Studies in migrant populations can illuminate the interplay of genetic and environmental factors. Exposures related to bad housing (indoor dampness, mould growth, crowding etc.) are likely to play a role in how socioeconomic inequalities can turn into health disparities for disadvantaged populations. The sizable immigrant population living in very poor-quality housing in Malmö, Sweden, became the focus of a cross-sectional study.

Objective

To describe atopic disorders and sensitizations in a population living in substandard housing in Malmö, Sweden, with an emphasis on their relation to harmful exposures from the built environment.

Methods

Families were recruited via identification of any children with symptomatic airway afflictions from health care records, and also asymptomatic children from school lists. Interviewer-led health questionnaire data and data from self-reports about living conditions were obtained together with data from home inspections carried out by health communicators. Families underwent skin prick tests (SPT) against common aeroallergens.

Results

As could be expected from background demographic information, it turned out that we effectively studied an immigrant population inhabiting very precarious housing outside the center of Malmö. A total of 359 children from 130 families (total 650 participants) were included. Overall the prevalence of potentially harmful environmental exposures was high (signs of moisture or mould in more than 50% of apartments, indoor smoking in 37% of households). Atopic disorders were common among both adults and children. SPTs showed a spectrum of sensitizations consistent with unselected populations in Sweden. Paternal sensitization in the SPT was associated with higher risk of sensitization for offspring than maternal sensitization. Few statistically significant associations of atopic sensitization with studied environmental exposures were detected (for example objective signs of dampness /mould in bathrooms). There were marked discrepancies between asthma diagnoses obtained from the health records and parental reports of such diagnoses and treatment for their children.

Conclusions

The atopic burden in this selected immigrant population was high, and results point to unmet medical needs. Health care systems caring for such populations need to be aware of their specific health needs; comprehensive asthma and allergy care should include consideration of harmful environmental exposures, adhering to the precautionary principle.

Immigrant Respiratory Health: a Diverse Perspective in Environmental Influences on Respiratory Health

PURPOSE OF REVIEW

The aim of this review is to examine the prevalence of and impact of environmental exposures in the workplace and home on immigrant respiratory health in the USA.

RECENT FINDINGS

Few studies report levels of workplace and home environmental exposures for immigrant children and adults, and documenting these findings is an important first step to addressing their respiratory health concerns. Rates of respiratory disease are lowest upon first arrival and increase with duration of residency in the USA. Community Health Workers may be an efficacious intervention to reducing exposures and improving lung health among immigrant populations. Immigrant children and adults have a high risk of occupational and home environmental exposures that can negatively affect their respiratory health. While limited studies exist, more documentation of these exposures and their impact on immigrant person's respiratory health are needed to begin to tackle these disparities.

The Parenting Journey: Daily Parental Management in Families with Young Children

Transitioning to parenthood and establishing a family are significant life events, and although an expected and normal part of adult life, it is a time of stress, change, and learning. The family has been well-studied with regard to developmental norms and the diagnosis and treatment of physical, cognitive, and emotional problems. However, little is known about how parents of young children establish, manage, and maintain their families on a daily basis. Social constructivist grounded theory was used to examine day to day parental management in families with young children. A theory, adjusting and redefining priorities, was developed to explain how parents make decisions related to the health and well-being of family members. A group of 24 New Zealand parents was interviewed about their daily management in families where the eldest child was aged no older than 3 years. Findings of this study revealed that parents used 4 overarching and constantly interacting viewpoints to consider situations: the personal, the parent, the parent unit, and the family unit. Their learning went through cycles of intensity and relaxation as parents considered their short term and long term priorities. Sometimes major changes to family structures and processes were required to maintain family stability, and sometimes the adjustments needed were relatively minor. These dimensions contributed to parents' continuous efforts to meet the needs of all family members and to create a unique family environment that encompassed the guiding principles upon which parents made their decisions. This study highlights the need for health professionals to recognize the unique, complex and dynamic decision-making process parents are already engaged in when managing their families.

Differences in health symptoms among residents living near illegal dump sites in Los Laureles Canyon, Tijuana, Mexico: a cross sectional survey

Living near landfills is a known health hazard prompting recognition of environmental injustice. The study aim was to compare self-reported symptoms of ill health among residents of four neighborhoods, living in haphazardly constructed settlements surrounded by illegal dumpsites in Tijuana, Mexico. One adult from each of 388 households located in Los Laureles Canyon were interviewed about demographics, health status, and symptoms. Distance from each residence to both the nearest dumpsite and the canyon bottom was assessed. The neighborhoods were selected from locations within the canyon, and varied with respect to proximity to dump sites. Residents of San Bernardo reported significantly higher frequencies of ill-health symptoms than the other neighborhoods, including extreme fatigue (OR 3.01 (95% CI 1.6-5.5)), skin problems/irritations (OR 2.73 (95% CI 1.3-5.9)), stomach discomfort (OR 2.47 (1.3-4.8)), eye irritation/tears (OR 2.02 (1.2-3.6)), and confusion/difficulty concentrating (OR 2.39 (1.2-4.8)). Proximity to dumpsites did not explain these results, that varied only slightly when adjusted for distance to nearest dumpsite or distance to the canyon bottom. Because San Bernardo has no paved roads, we hypothesize that dust and the toxicants it carries is a possible explanation for this difference. Studies are needed to further document this association and sources of toxicants.

Exploring Household-level Risk Factors for Self-reported Prevalence of Allergic Diseases Among Low-income Households in Seoul, Korea

PURPOSE

Indoor risk factors for allergic diseases in low-income households in Korea have been characterized only partially. We evaluated the prevalences of atopic dermatitis, asthma, and allergic rhinitis in Seoul, Korea, to identify key housing and behavioral risk factors of low-income households.

METHODS

Statistical analysis of the prevalence of these diseases and various risk factors was conducted using data from a 2010 Ministry of Environment household survey. Logistic regression models were generated using data from 511 low-income household apartments in districts of Seoul.

RESULTS

In general, housing factors such as renovation history (P<0.1) and crowding status (P<0.01) were associated with allergic rhinitis, whereas behavioral factors such as frequency of indoor ventilation (P<0.05) and cleaning (P<0.1) were inversely correlated with atopic dermatitis. Indoor smoking was a major trigger of asthma and atopic dermatitis in low-income households (P<0.05). The presence of mold and water leakage in houses were the most important risk factors for all three diseases (P<0.05).

CONCLUSIONS

Various risk factors play a role in triggering allergic diseases among low-income households in Seoul, and health or environmental programs mitigating allergic diseases should be tailored to address appropriate housing or behavioral factors in target populations.

Association between birthplace and current asthma: the role of environment and acculturation

OBJECTIVES

We evaluated associations between current asthma and birthplace among major racial/ethnic groups in the United States.

METHODS

We used multivariate logistic regression methods to analyze data on 102,524 children and adolescents and 255,156 adults in the National Health Interview Survey (2001-2009).

RESULTS

We found significantly higher prevalence (P < .05) of current asthma among children and adolescents (9.3% vs 5.1%) and adults (7.6% vs 4.7%) born in the 50 states and Washington, DC (US-born), than among those born elsewhere. These differences were among all age groups of non-Hispanic Whites, non-Hispanic Blacks, and Hispanics (excluding Puerto Ricans) and among Chinese adults. Non-US-born adults with 10 or more years of residency in the United States had higher odds of current asthma (odds ratio = 1.55; 95% confidence interval = 1.25, 1.93) than did those who arrived more recently. Findings suggested a similar trend among non-US-born children.

CONCLUSIONS

Current asthma status was positively associated with being born in the United States and with duration of residency in the United States. Among other contributing factors, changes in environment and acculturation may explain some of the differences in asthma prevalence.

Predictors of tobacco outlet density nationwide: a geographic analysis

OBJECTIVE

To elucidate how demographics of US Census tracts are related to tobacco outlet density (TOD).

METHOD

The authors conducted a nationwide assessment of the association between socio-demographic US Census indicators and the density of tobacco outlets across all 64,909 census tracts in the continental USA. Retail tobacco outlet addresses were determined through North American Industry Classification System codes, and density per 1000 population was estimated for each census tract. Independent variables included urban/rural; proportion of the population that was black, Hispanic and women with low levels of education; proportion of families living in poverty and median household size.

RESULTS

In a multivariate analysis, there was a higher TOD per 1000 population in urban than in rural locations. Furthermore, higher TOD was associated with larger proportions of blacks, Hispanics, women with low levels of education and with smaller household size. Urban-rural differences in the relation between demographics and TOD were found in all socio-demographic categories, with the exception of poverty, but were particularly striking for Hispanics, for whom the relation with TOD was 10 times larger in urban compared with rural census tracts.

CONCLUSIONS

The findings suggest that tobacco outlets are more concentrated in areas where people with higher risk for negative health outcomes reside. Future studies should examine the relation between TOD and smoking, smoking cessation, as well as disease rates.

Extermination strategies reported in the NYC Health and Nutrition Examination Survey, 2004: prevalence and predictors

It is likely that household extermination is a major source of pesticide exposure for urban residents. Little is known about the predictors of residential pest control strategies in urban areas, and greater knowledge of these may help identify who is at risk for higher pesticide exposure. Study data is from the 2004 NYC Health and Nutrition Examination Surveys, a cross-sectional, population-based study using a three-stage sampling scheme. Logistic regression was used to identify predictors of pesticide use overall, and of application strategy: (1) consumer-applied pesticides only, (2) use of a professional exterminator only, or (3) use of both. Consumer-applied extermination was more prevalent than professional or both professional and consumer (39.9% versus 27.8% and 15.9%, respectively, and non-exclusively). In multivariate models among those who used any extermination, consumer application was associated with age 60 years+, being black or Asian, and being widowed, divorced, or single. Lower income households were more likely to use both strategies, and less likely to use professional extermination only. Urban residents may benefit from targeted education on how and when to self-apply pesticides, and on best-practice pest control to avoid unnecessary pesticide exposure. Higher prevalence of consumer-applied and conjoint consumer and professionally applied extermination in low-income households may reflect both economic determinants of first recourse and higher neighborhood infestation levels.

Safety practices in relation to home ownership among urban Mexican immigrant families

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.
