Racial-Ethnic Differences in Care Networks of Older Adults: Empirical Exploration of Possible Explanations - PubMed The findings highlight the need for more research and policy interventions to address the diverse challenges faced by socially disadvantaged older adults.

We often link racial differences in elder care to cultural values. New research says the bigger story is structural. Black and Hispanic older adults rely more on family caregivers not due to stronger family values but lower marriage rates, lower incomes, and less access to paid care.

The Economics of Childbearing: Trends, Progress, and Challenges The neoclassical economics of childbearing turns 65 this year, marking the anniversary of Gary Becker's foundational article on the subject in 1960. This review article begins with a study of how...

Can a warm and supportive adult protect against mental health problems amongst children with experience of adversity? A twin-differences study - PubMed The apparent protective effect of a warm, supportive adult against mental health problems following ACEs is largely explained by genetic and environmental confounding. This suggests that…

We've long believed a supportive adult can shield children from the mental health effects of adversity. New research says it's more complicated. A study of 2,000+ twins found that when genetics and family environment are accounted for up to 81% of that protective effect disappears. 📖

Neighborhood socioeconomic disadvantage and child health: The role of neighborhood mobility networks - PubMed Despite a large body of work on neighborhood effects on health, past studies are limited in their treatment of neighborhoods as largely static spaces with (dis)advantages based primarily on the…

No neighborhood is an island. The places your community travels to every day — stores, schools, parks — form a network that shapes children's health. New research shows that network can matter more for child health than where a child actually lives.🔗

What does research say about how Black and Native American families navigate a child's serious illness? Almost nothing—because almost no one has asked. Of 2,762 studies, only 6 included Black families. Zero included Native American families. To improve care, we first have to look. 🔗 buff.ly/baLUGgQ

Childhood fluoride exposure and cognition across the life course - PubMed How are children's fluoride exposures associated with cognitive test performance in adolescence and midlife? Whereas most prior research has estimated effects of exposure to extremely high levels of…

Is fluoride in tap water bad for kids' brains? A a new nationally representative U.S. study finds that kids exposed to recommended fluoride levels in tap water scored modestly *better* on math, reading & vocabulary in high school — with no cognitive harm detected at midlife. 🔗

According to new research, by 2030, a sustained 1% annual drop in MMR coverage could lead to:

17,000 measles cases/year
4,000 hospitalizations/year
$1.5 billion in added annual costs/year

But this potential for cascading impacts from declining vaccine uptake is not inevitable.

When states require fully insured employers to cover in vitro fertilization (IVF), what do self-insured employers provide? - PubMed While state in vitro fertilization coverage mandates are important policy initiatives to improve access to in vitro fertilization, our findings suggest that state mandates are insufficient to expand…

Living in a state with an IVF insurance mandate? Your employer may still not cover it. A new study finds that only 41% of self-insured employers in mandate states cover IVF. Federal action may be the only way to close the gap. 📖

School Climate and Sleep Duration Among Adolescents at the Intersection of Multiple Social Positions - PubMed Findings underscore the impact that schools have on adolescents' sleep health. Our study indicates that adolescents with multiple minoritized social positions face additional challenges impacting…

⏰️ Teens average just 6.75 hours of sleep on school nights. A more positive school climate is linked to longer sleep—about 25 extra minutes per night. Students with multiple minoritized identities who perceive negative school climates sleep the least. 🔗

Associations between wildfire smoke exposure and health-related quality of life: findings from the Lovelace Smokers Cohort - PubMed Exposure to WFS was associated with worse SGRQ and SF-36 scores, with notable differences in temporal patterns between mental and physical health measures.

Don’t Panic: Population Projection is Not a Crystal Ball The best way to get those dozens of rates for each year is to rely on current rates and recent trends. This works well when things are changing slowly and in predictable ways, but it means our projections are often limited to forecasting a future that’s a lot like the present.

CPC Director Karen Guzzo and co-authors argue that population projections aren't a 'crystal ball' and become less accurate as researchers project farther from the present.

Workers are making over $1 million by secretly holding down multiple gigs—and they're doing it all within the 40-hour workweek Holding multiple full-time jobs may sound impossible, but these overemployed remote workers are managing to squeeze in two to three jobs within a regular workweek—no overtime needed.

Are we starting to see multiple remote jobs as the norm? PSC researcher Jerry Jacobs comments in @fortune.com on the shifting trends in work habits.

Our first Brown Bag Seminar of the academic year is Wednesday, September 3rd at 12pm PST. Ian Lundberg (UCLA) will present on "Non-Existent Outcomes in Research on Inequality: A Causal Approach."
