Poor birth outcomes increase with poverty | Harvard T.H. Chan School of Public Health Inequities in birth outcomes are staying consistent—if not widening—between economic groups, according to a new Harvard Chan School study.

Our director, @ritahamad.bsky.social and @emilydore.bsky.social are authors on this paper profiled in this news piece…

Line graphs show trends in gestational age outcomes by poverty status from 2012-2022. Graph A shows preterm birth percentages; graph B shows average gestational age in weeks for <200% of FPL and >200% of FPL.

Low-income mothers had persistently worse birth outcomes from 2012 to 2022, with widening disparities in low birth weight, indicating a continued need for supportive policies.

Trends in Poverty and Birth Outcomes in the US This cross-sectional study uses data from the Pregnancy Risk Assessment Monitoring System to examine the relationship between poverty status and birth outcomes in the US.

CDC staff in charge of data we used (PRAMS) were put on leave last year. PRAMS is only national survey dedicated to perinatal health, and it is no longer available to researchers. This study shows how important these data are to understand national trends. @dataindex.us @datarescueproject.org 3/3

These disparities highlight need for support during pregnancy & birth for low-income families.
Antipoverty policies provide resources to promote maternal & child health, but generosity of programs vary by state. And these programs have been undermined in past year. www.doi.org/10.1001/jama... 2/

The Day Federal Data Went Dark: A Year of Monitoring and Action January 31, 2025, is infamous as the day thousands of federal datasets and webpages went dark. While many of these resources have since been restored–often after being scrubbed of references to gender, DEI, and climate–they continue to face significant risks. In the webinar, we mark the one-year anniversary of this takedown to discuss the current state of federal data and recognize the immense amount of work that has been done to defend these public resources. Leaders from the data community will share insights on monitoring tools they have developed and the actions being taken to safeguard essential federal data. This webinar is cohosted by dataindex.us and the Association of Public Data Users. 0:00 Introduction 2:53 EssentialData.US x Federation of American Scientists 6:51 American Statistical Association 10:31 CDC Data Project 14:17 Friends of BLS 17:50 Public Environmental Data Partners 21:24 The Leadership Conference Education Fund 26:26 Movement Advancement Project 30:37 Population Association of America 35:05 Democracy 2025 40:42 Data Rescue Project 44:16 Population Reference Bureau 47:14 Association of Public Data Users 50:10 dataindex.us 55:19 Conclusion

Thank you to everyone who joined us for our webinar, The Day Federal Data Went Dark: A Year of Monitoring and Action. We are grateful to be in a community with so many amazing organizations.

You can watch the recording to learn about more than a dozen efforts to monitor and safeguard federal data.

Honored to be new director @harvardpopcenter.bsky.social, following in Lisa Berkman's footsteps. I'm excited to inherit a brilliant & dedicated staff + network of research & community affiliates. Looking forward to advancing our mission of improving wellbeing of global populations! @hsph.harvard.edu

Some important points from new study: if you describe specific safety net programs (eg SNAP, unemployment insurance) instead of generic "welfare programs," people are more likely to tolerate slightly higher fraud to ensure access. There is always this trade-off; framing matters. @donmoyn.bsky.social

@christinajcross.bsky.social's fabulous book painstakingly details how family structure is - and isn't - related to children's academic achievements, including insights into why pushing marriage won't alleviate race and ethnic differences in achievement.

"I strongly support extending PRAMS for another 3 years. My work [insert text]. PRAMS is the only national data source that examines women’s experiences before, during, and after pregnancy. PRAMS allow states, practitioners, and researchers to identify emerging risks and design programs to address maternal and child health. Without PRAMS, we lose a critical national tool for monitoring maternal and infant health and for guiding policies that improve outcomes for families. Continued investment in PRAMS is essential to protecting maternal and infant well-being."
