THE CHILDREN OF PRISONERS
Racial and ethnic differences in sexually transmitted infection (STI) and HIV rates emerge during adolescence and widen during young adulthood. Substance use is a critical behavioral determinant of STI/HIV risk. These authors considered whether parental incarceration also contributes to both substance use and STIs. They reported that children under 18 whose parents are incarcerated are at higher risk for STI/HIV in both adolescence and adulthood, with the strongest effects among non-Whites. Black children under 8 years old whose parents were incarcerated were twice as likely to use marijuana as adults and four times as likely to use cocaine. Half of all American children who have an incarcerated parent are Black. Children impacted by parental incarceration are in greatest need of substance use and STI/HIV prevention and treatment.
FINANCIAL STRESS AND TRYING TO QUIT SMOKING
Despite national declines in smoking rates, 26% of those living below the poverty threshold continue to smoke. The added expense of smoking may contribute to the financial strain experienced by persons with lower income. Yet tobacco use increases during times of financial stress; fewer smokers quit and those who do face a greater likelihood of relapse. These authors examined whether financial strain in low-income adults increases the severity of perceived post-quit nicotine withdrawal symptoms, making it more difficult not to relapse after a quit attempt. They found that greater financial strain exacerbated post-quit anger, anxiety, and sleep disturbance, which contributed to a return to smoking. The authors speculate that behavioral strategies, such as offering financial incentives early in a quit attempt or providing financial education in conjunction with nicotine replacement therapy, may alleviate financial strain, reduce withdrawal symptom severity, and improve smoking cessation outcomes.

PARTICULAR PARTICULATES
Racially or ethnically marginalized and poor communities in the United States are more likely to have nearby landfills and industrial sites producing pollution than majority White, affluent communities. These facilities emit harmful air particulates that impact lung and heart health. Particulate matter (PM) in the air is a combination of solid and liquid pollutants. In general, the smaller the particles, the more harmful to health. An April 2018 report offers the latest findings on the health impacts of disparate exposure to PM2.5, or particulate matter smaller than 2.5 micrometers in diameter.
The figure above depicts the distribution of the PM2.5 burden, or the average tons of PM2.5 emitted per year at close proximity, by race, ethnicity, and poverty status. Hispanic and Black people tend to have a higher PM2.5 burden than their White counterparts. Also, those below the federal poverty line experience more exposure to PM2.5 than those with higher incomes. Fifteen percent of the population is exposed to more PM2.5 per year than the average 22.4 tons. This includes all groups.
PM2.5 is associated with a higher risk of illness and death, and Black populations have a higher prevalence of heart disease and asthma than White populations. The report’s findings confirm previous research documenting disproportionate exposure to harmful particulate matter in communities of color.
