Neighborhood Disadvantage and Biological Aging 🧵1/5

"Despite moving, they often still reside in economically disadvantaged areas. They are what Wilson (1987) calls 'truly disadvantaged'"

"there is a strong association between age and DNA methylation"
"Indeed, chronological age is much more strongly related to methylation based aging than to telomere length or other biological markers of aging"

"..living in disadvantaged neighborhoods, ambient threat, social strain, social isolation... influences health-related outcomes"
"Mean ages predicted by the Hannum’s methylomic index were 1.22 years higher than the actual chronological age of the sample. 54% of respondents had a methylomic age greater than their chronological age. This indicates a tendency in the sample toward accelerated aging."
"...this finding supports the theoretical view that the ambient stress of disadvantaged neighborhoods fosters biological wear and tear throughout the life course...and that effects are not entirely attributable to individual level financial strain or health behaviors...."
"..individuals with a biological age one year greater than their chronological age showed a 6% increased risk of getting cancer within three years and a 17% increased risk of cancer death within five years"

This is the woman who is credited with coining the term "Opression Olympics"
–cosigned by Angela Y. Davis

🧵1/8 Image
Born in 1925, she grew up in a white neighborhood, went to white schools, worked at white jobs, and married white men (pic 2, 2nd husband)

Keep this in mind, this person grew up and lived her entire life clearly on the white side of the color line, during the era of Jim Crow ImageImage
Pic 1 is the wiki summary on the first usage of the term, and pics 2-4 are excerpts from that 1993 conversation

Angela Davis: "A "Black" subject was created. We can also create a "women of color" subject." 🚩

"Black women are especially vulnerable to weathering effects when high rates of male unemployment and incarceration in the community thrust them into a role of supporting multiple generations of dependents but with resources only accessible from low-income jobs" Simons,et al 2018
Weathering starts early in life and continues to have damaging effects on health throughout life (Simons et al., 2018)

The health and life expectancy of Black ppl are negatively affected by the cumulative experiences of racism throughout life (Paradies, 2006;Phelan & Link, 2015)
Black women are four to five times more likely to die during
pregnancy and childbirth than white women, regardless of income, education, or lifestyle
(Bingham et al., 2011; Bond, 2011)

"...lawyers who established the Mexican Americans' legal "canon" employed arguments—which were also based on the Fourteenth Amendment—that called for better policing of the existing boundaries of Jim Crow, rather than for the dismantling of the system." 🧐
"The state law defined the 'colored' class to include "all persons of mixed blood descended from Negro ancestry."

"..that as Hispanics, Mexicans belonged to the white race, albeit to an inferior branch in the taxonomy."

"..all Mexicans, without discrimination as to color."🧐
"The founders of LULAC aimed to intergrate Mexican-descended persons into the U.S. mainstream, that is, to 'Americanize' the community."

"Mexican Americans grew dependant on legal arguments that relied heavily on alleged advantages derived from their "white" status."
