The role of housing characteristics in biomarkers: US NHANES, 2003-2006

A decade of research on housing and health: a systematic literature review

This paper provides a systematic review of the evidence linking housing and health. This involved a review of 59 peer-reviewed journal papers, that included case studies on the health impacts of housing and were published in English, in the past decade (2010-2020). Our systematic review of the literature suggested most of the research on the health impacts of housing employed quantitative methodology, were conducted in the Global North and were published in Medical and Health Sciences journals. Research findings demonstrated four key areas through which housing impacts health: neighbourhood or context, physical building, housing market and housing policy. This paper provides valuable information to researchers for future research directions on the associations between housing and health and to decision-makers and planners for planning healthy cities.

Neighborhood disorder predicts lower serum vitamin D levels in pregnant African American women: A pilot study

Pregnant African American women are more likely to live in neighborhoods with more disorder (e.g., vacant housing, littler, crime) and to have vitamin D deficiency due to their darker skin pigmentation and poor production of vitamin D [25(OH)D] from ultraviolet rays. However, no study has examined the potential link between neighborhood disorder and 25(OH)D status in African American pregnant women. Forty-one pregnant African American women completed validated questionnaires about perceived neighborhood disorder (6 items; 3-point scale; range 6-18) and with concurrent serum levels of 25-hydroxyvitamin D [25(OH)D] assessed during pregnancy at 18-24 weeks gestation. Higher levels of perceived neighborhood disorder were associated with lower levels of serum 25(OH)D. Pregnant African American women who report higher disorder in their neighborhood may spend less time outside. Health care providers should include assessment of perceived neighborhood disorder. Future research needs to evaluate the relationships among neighborhood disorder and 25(OH)D levels among pregnant African American women.

Short residence duration was associated with asthma but not cognitive function in the elderly: USA NHANES, 2001-2002

There has been a growing interest in how the built environment affects health and well-being. Housing characteristics are associated with human health while environmental chemicals could have mediated the effects. However, it is unclear if and how residence duration might have a role in health and well-being. Therefore, the aim of the present study was to investigate the associations among residence duration, common chronic diseases, and cognitive function in older adults in a national and population-based setting. Data were extracted from the US National Health and Nutrition Examination Survey, 2001-2002, with assessment information on demographics, lifestyle factors, housing characteristics, self-reported common chronic diseases, and cognitive function by using the digit symbol substitution test from the Wechsler Adult Intelligence Scale (a measurement of attention and psychomotor speed). Statistical analyses including the chi-square test, t test, and survey-weighted general linear modeling and logistic regression modeling were performed. Residence duration was significantly associated with risk of asthma but not with other chronic disease, showing a longer stay in the same housing leading to lower risk of asthma (OR 0.43, 95%CI 0.27-0.69, P = 0.002) among the American older adults. However, having asthma was not associated with cognitive function decline. In conclusion, residence duration was found to be associated with risk of asthma but not cognitive function. Future research examining the relationship of residence duration and cognitive tests by other domains of cognitive function following asthma episodes would be suggested. For practice and policy implications, familiarity with the housing environment might help with lessening respiratory symptoms.

Does disorder get "into the head" and "under the skin"? Layered contexts and bi-directional associations

This paper utilizes a layered context approach to examine how neighborhood and household conditions are associated with the objective and subjective well-being of older adults. Using two waves of data from the National Social Life, Health, and Aging Project (n=2261), we assess subjective mental health through self-reported measures of perceived stress and distress and objective physical health through C-reactive protein (CRP). Environmental disorder was measured by independent, trained interviewers. Cross-sectional results indicate that household disorder is positively associated with perceived stress and distress, overwhelming the association between neighborhood disorder and mental health outcomes. Yet longitudinal findings point to a reverse process, whereby highly stressed women experience deterioration in their home environment across the two waves. Few significant findings surfaced for CRP. Taken together, our findings illustrate the complex interplay between health and proximal environments and underscore how feedback cycles operate between "health" and "place" across multiple outcomes.

Relationship of environmental exposures and ankylosing spondylitis and spinal mobility: US NHAENS, 2009-2010

It was aimed to study the relationships of different sets of urinary environmental chemical concentrations and ankylosing spondylitis in a national and population-based setting. Data were extracted from United States National Health and Nutrition Examination Surveys, 2009-2010. Information on demographics was obtained by household interview and ankylosing spondylitis clinical measures and urines were taken at examination. People with abnormal occiput-to-wall distance were found to have higher urinary cadmium (OR 2.17, 95 % CI 1.34-3.52, p = 0.004), antimony (OR 1.74, 95 % CI 1.15-2.62, p = 0.012), tungsten (OR 1.91, 95 % CI 1.39-2.64, p = 0.001), uranium (OR 1.49, 95 % CI 1.03-2.15, p = 0.036), and trimethylarsine oxide (OR 5.01, 95 % CI 2.34-10.71, p < 0.001) concentrations. Moreover, people who resided in older households tended to have abnormal ankylosing spondylitis clinical measures, compared to those who resided in households that were built in 1990 or after. The odds were 1.74 for households built in 1978-1989 and 1.81 for those built in 1940 or earlier.
