“Since asthma surveillance data were not available at the census tract level for most of Louisiana, we estimated asthma burden using the inpatient discharge data available through LDH.”  (4)

“Case counts are not provided for CTs with a 2018 population of less than 800 to safeguard privacy.” (4)

“To minimize the need for suppression, inpatient discharge data was aggregated for the three most recent years available (2017–2019) and average annual crude rates were calculated for cases where asthma (ICD-10 code J45) was the primary diagnosis, as well as where asthma was any diagnosis.” (4)

“Spearman’s Rank Correlation was utilized to analyze the correlation between various social and environmental vulnerability factors, COVID-19 incidence, and the measures of asthma risk by CT.” (4)

 

“This was performed by first ranking the values in each dataset using RANK.AVG function in MS Excel 2016, followed by applying the PEARSON function to compare two datasets. Significance was set at alpha less than 0.05 (α < 0.05), with degrees of freedom (df) equal to two less than the total number of data points represented in both datasets” (4)

The research team works for the Section of Environmental Epidemiology and Toxicology, Office of Public Health, Louisiana Department of Health in Baton Rouge. Team members included Arundhati Bakshi; Shanon Soileau; Collete Stewart; Kate Friedman; Collete Maser; Alexis Williams; Kathleen Aubin; and Alicia Van Doren. 

How are the links between environmental conditions and health articulated?

“Currently, much of the environmental focus of the pandemic remains on PM2.5 levels; however, we noted that higher levels of ozone was consistently associated with higher incidence rates of COVID-19, and it was the only environmental factor that appeared to have an additive effect over SVI on COVID-19 incidence (Fig 1).” (11)

“Specifically, our data show a moderately strong positive correlation between SVI due to minority status/language barrier and three health data variables: asthma hospitalization; estimated asthma prevalence; and cumulative COVID-19 incidence at 3 months (Table 2). Interestingly, SVI measures were either negatively or not significantly correlated COVID-19 incidence at the 9-and 12-month time points, indicating that social vulnerability factors may have played a greater role in COVID-19 spread early in the pandemic, but may have been of diminishing importance as the pandemic wore on (Fig 1 and Table 2).” (9)

What forms of evidence and expertise are used in the document?

This document uses data resources from the Center for Disease Control/Agency for Toxic Substances and Disease Registry (CDC/ATSDR), the Environmental Protection Agency (EPA), and the Louisiana Department of Health (LDH).

These data resources include the Social Vulnerability Index (2018 - CDC/ATSDR), the NATA Respiratory Hazard Index (EPA 2014), PM2.5level (average annual concentration in ug/m3, EPA 2016), ozone level (summer seasonal average of daily maximum 8-hour concentration in air in parts per billion, EPA 2016), indoor mold concerns reported to IEQES program (average annual number of calls, LDH 2017-2019), cumulative COVID-19 incidence rate at 3-, 6-, 9- and 12-month increments (LDH March 2020 - March 2021), asthma hospitalization (average annual crude rate, where asthma was a primary diagnosis among hospitalization cases, LDH 2017-2019), and estimated asthma prevalence (average annual crude rate, where asthma was any diagnosis among hospitalization cases, LDH 2017-2019).

Lead Hazard

karishmakkhanal
Annotation of

WHAT (& WHAT FOR): Lead is a metal often found in pipes, and in old paint (before it was banned in paint in the late 1970s). Before 1996, lead also found in vehicle fuel resulting in  soil contamination in many communities from both paint dust and vehicle pollution. 

HEALTH IMPACT: Lead is a neurotoxin and is known to have no safe blood lead level in children. 

Has been linked to:

  1. Brain swelling, anemia, seizures, renal failure, reduced IQ, and ADHD

  2. Damages brain development in children

  3. Connected to behavioral problems like aggression and bullying, and internalizing problems such as depression and anxiety 

LOCAL IMPACT: Recent research in Santa Ana has shown that there is a disproportionately impact of solid lead contamination crisis on lower income, people of color communities. 

POSSIBLE RESPONSES: There are many ways to respond to lead contamination:

  1. Providing special health care for children with high blood lead levels, and investigating possible sources of lead exposure in homes, daycares and school, playground, etc.

  2. Implement strict housing policies where landlord and city housing officials are required to have lead inspections of homes for lead paint hazards (especially in low income, people of color communities)

  3. Requiring a minimum reduction standard for lead paint in older homes 

  4. Requiring blood lead level test as part of the routine check up for children (extremely important for children in low-income housing)

Byron Good, Ph.D., is a professor of Medical Anthropology at Harvard Medical School. His primary area of research is mental illness and how social perceptions evolves around these issues, in terms of both treatment and social acceptance. Dr. Good has several works on these issues, including several that explore the perspective of bio-medicine in non-western medical knowledge, the cultural meaning of mental illness, and patient narrative during illness. His publications including several papers, books, and edited volumes; he is regarded as a major contributor to the field of psychological anthropology.

The article primarily asserts that how a patient narrates or describes their medical history is deeply rooted in their native culture. As such, physicians must be aware of how an individual's medical experiences can be altered based on this. In turn, physicians must recognize the importance of story-telling and anecdotes when receiving information directly from patients. Narratives project the patient's experience and events through their perspective, granting professionals a glimpse into their thought processes and action patterns.

The article’s main argument is that the narration of an illness is founded in the emotional connection it has to the sufferers life, the place from which they view the illness which includes individual and cultural aspects. Furthermore any lack of factual accuracy is an indicator of the social and cultural environment in which the illness presents itself and is revealing as to how it will be perceived and treated.

The main argument is supported primarily through interviews with many individuals living in Ankara, through which they describe the first presentation of their seizures and in many cases the steps they tool to attempt a cure. Along with the interviews, statistics of the individuals interviewed and their diagnoses is used to provide a reference point to better understand their stories. Finally the article includes an analysis of narratives in a more general sense that can be applied to the narrative of an illness.

  • “… illness narratives - both the corpus of story episodes and the larger life "story" or illness narrative to which they contribute - have elements in common with fiction. They have a plot; succession is ordered as history or event, given configuration.” (164)
  • “The diverse accounts of the illness in these narratives represent alternative plots, a telling of the story in different ways, each implying a different source of efficacy and the possibility of an alternative ending to the story. My point is not that persons having access to a plural medical system do not simply choose among alternative forms of healing but instead draw on all of them” (155)
  • “Predicament, human striving, and an unfolding in time toward a conclusion are thus central to the syntax of human stories, and all of these, as we will see, are important to stories about illness experience.” (145)
