Sunscreen produces persistent free radicals when exposed to light, a recent study finds
Arnold School of Public Health
New research from the Department of Environmental Health Sciences explores how common sunscreen ingredients behave under light exposure. Led by associate professor Eric Vejerano, the team tested seven commercially available sunscreens (including four mineral-based formulas) and found that every sample produced persistent free radicals (PFRs) when exposed to artificial light. The study, published in Environmental Science & Technology Letters, provides new insight into sunscreen photochemistry and may help guide future evaluations of product performance and safety.

Measles outbreak surveillance confirms utility of wastewater-based epidemiology for monitoring infectious disease surges
Arnold School of Public Health
New research led by environmental health sciences assistant professor Laura Langan has provided further support for the effectiveness of wastewater-based epidemiology (WBE). Langan and her team compared two of the most common approaches to WBE for monitoring the spread of an active measle outbreak in Texas: reverse transcription-quantitative polymerase chain reaction (more widely available) and RT digital PCR.

Researchers untangle residence and race when looking at postpartum hospital readmissions
Arnold School of Public Health
USC researchers continue to uncover new insights from a five-year project launched by health services policy and management associate professor Peiyin Hung and health promotion, education, and behavior professor Xiaoming Li to investigate maternal care and outcomes, particularly in the wake of the COVID-19 pandemic. Last year, their team received a $200,000 supplement to the initial $3 million National Institutes of Health U01 grant to further explore postpartum trends related to the intersection of residence location and race/ethnicity.

More and more pregnant people are planning births outside of hospitals, but at what risk?
Arnold School of Public Health
A recent study led by Ph.D. in Epidemiology candidate Marion Granger Howard and published in JAMA Pediatrics (the highest-ranked journal in the field) compared the health outcomes of planned hospital births vs planned community births (i.e., births that were intended to take place at home or at a birthing center). The researchers found that individuals who planned community births and actually delivered in those settings experienced lower risks of adverse health outcomes. However, those who planned community births at the onset of labor but then transferred to a hospital had increased odds of medical interventions and negative outcomes.

Half of rural SC families bypass local hospitals to deliver their babies in urban settings and experience worse outcomes
Arnold School of Public Health
Rural and maternal health expert Peiyin Hung has published new research on maternal health outcomes based on the hospital locations where rural South Carolinians give birth. Published in JAMA Network Open, the health services policy and management (HSPM) associate professor and her co-authors* found that 47% of rural mothers are opting to deliver in urban hospitals over local facilities. These rural residents had higher risks of severe maternal morbidity and mortality.

Maternal mental wellbeing shapes children’s early cognitive development, GUSTO study finds
Agency for Science, Technology and Research (A*STAR), Singapore
A Singapore study tracking 328 mother-child pairs has found two distinct pathways linking maternal mental health to child outcomes at age four. The research from A*STAR Institute for Human Development and Potential (A*STAR IHDP), in collaboration with the Yong Loo Lin School of Medicine, National University of Singapore (NUS Medicine), and KK Women's and Children's Hospital (KKH), draws on data from the Growing Up in Singapore Towards healthy Outcomes (GUSTO) birth cohort.

Obesity, treatment, and shame
Wroclaw Medical University
A study by researchers from Wroclaw Medical University shows that although most Polish women recognize obesity as a disease requiring treatment, pharmacotherapy is still sometimes perceived as a “shortcut.” In a survey of 1,043 adult women in Poland, 97% agreed that obesity is a disease, yet older respondents were more likely to express stigmatizing attitudes toward anti-obesity drugs, while women with higher BMI more often felt shame about seeking treatment. Importantly, women who had personal experience with medication showed significantly lower levels of stigma. The findings highlight the need to shift the public debate from moral judgments about willpower to a medical understanding of obesity as a complex chronic disease.

Problematic social media use predicts higher depressive symptoms in adolescents under 16
Universidad Miguel Hernandez de ElcheAnalysing longitudinal data from 2,121 adolescents aged 13–15, researchers found that problematic social media use predicted increases in depressive symptoms one year later, particularly among younger teenagers and girls. Published in Scientific Reports, the study highlights how loss of control over social media use—rather than time spent online—may be a key mental health risk factor during early adolescence.
