Social Determinants of HealthAccording to WHO:
•“The circumstances in which people are born, grow up, live, work, and age, as well as the systems put in place to deal with illness. These circumstances are in turn shaped by a wider set of forces: economics, social policies, and politics.”

Compared to a White child in the affluent Oakland Hills, an African American child born in West Oakland is…
2 times more likely to be born low birth weight
12 times less likely to have a mother who graduated from college
13 times more likely to live in poverty
4 times less likely to read at grade level
5 times more likelyto be unemployed
3 times more likely to die of stroke

Adverse Childhood Experiences (ACES)
3 types• Abuse: phyical, emotional,
sexual
• Neglect: physical and emotional
• Household Dysfunction: mental illness (depression), domestic violence, divorce, drug use, prison

What is Stress? • Positive stress response
• Tolerable stress response
• Toxic stress response

In Alameda County
What % of kids in Alameda County have a diagnosis of asthma?
• A. 15%
• B. 25%
• C. 35%
• D. 45%
Over THREE TIMES the
national average!!

Who gets Asthma?
Blacks experience
more urgent care visits than Caucasians
higher asthma attack prevalence rate (19.2%) than Caucasians
higher rates of hospitalizations, 2.5 times greater than in Caucasians (Akinbami 2006).
165 % higher death rates than Caucasians (Akinbami2006).
Blacks of the same socioeconomic status and access to care still experience higher asthma morbidity (Gold)

Less Reversibility and Response to Bronchodilators In most asthmatics, 12%
reserversibility in FEV1 after treatment with albuterol
In AA, less than 5-8% response.

In Blacks with asthma >5 yrs, who are poorly controlled on low dose ICS, what is the preferred step-up therapy?
and
Does the degree of African ancestry affect preference for different therapies?

GIS Objectives
• To examine whether pre-existing chronic social and environmental exposures impact asthma treatment response
• Look at air pollution, crime statistics, SE conditions and look at spatial correlations between exposures and asthma outcomes.
![Page 28: Dayna Long, MD San Francisco Asthma Network Forum 10/10/14](https://reader030.vdocuments.net/reader030/viewer/2022032605/56812c28550346895d909cf6/html5/thumbnails/28.jpg)

• We see how early childhood experiences and stress are so important to lifelong outcomes and how the early social and environmental conditions literally becomes embedded in the brain, changes biologic function and then affect future generations.
