Childhood Trauma in Black Women Can Hurt Their Heart, Emory Study Finds
The heart remembers, at least when it comes to Black women who experience trauma or abuse as children, according to newly released research by Emory University.
Childhood exposure to trauma, emotional, sexual, and physical abuse may lead to heart disease in Black women, the new study showed. Meanwhile, such trauma and abuse didn't affect men's cardiovascular health in the same way, which may indicate women have more chronic stress, the research found.
The study, published in the Journal of the American Heart Association last month, shows that being exposed to trauma as a child can hurt a Black woman's vascular system — the arteries that circulate blood and fluids through the body — leading to heart disease.
The stressors of childhood trauma may cause stiffness or hardening of the arteries, or otherwise impair how they function, contributing to heart attacks and strokes, according to the study conducted through the Morehouse-Emory Cardiovascular (MECA) Center for Health Equity and released at the tail end of American Heart Month.
The study analyzed previous MECA clinical research involving slightly more than 400 Black adults in Atlanta ages 30 to 70 with a mean age of 53. About 60% of the study participants were women. That research explored the impact of individual, environmental, and biological factors that predispose Black Americans to either increased risk or resilience from cardiovascular disease.
The new research, which began in late 2023, focused on Black women to learn: Does early life trauma in childhood have any relationship to arterial stiffness and vascular dysfunction, considered preliminary indicators for cardiovascular disease?
Arterial stiffness is believed to lead to hypertension, or high blood pressure, because when the arteries don't expand and contract as they are supposed to, this results in increased pressure which the heart must pump against to move blood throughout the body, explained Telisa Spikes, lead author of the new study and a nurse and professor in Emory's nursing school. Her research primarily focuses on cardiovascular health in reproductive-age and early midlife Black women.
'This particular group of women has an increased risk of cardiovascular morbidity and mortality, and we don't know why,' said Spikes.
'Diet and activity does not fully account for the growing disparity in this particular group with increased hypertension in Black women compared to Black men. A precursor for hypertension might be related to psychosocial stressors,' such as childhood trauma, she said.
Participants in the original MECA study, recruited from 2016 to 2019, were considered healthy without a known history of preexisting cardiovascular or other chronic diseases, among other limitations.
As part of that research, participants reported to clinical researchers at Emory and Morehouse about experiencing childhood trauma, defined as distressing incidents that threaten the body, family, or social safety or security of someone under 18.
The experiences were emotionally painful or distressful, often resulting in negative mental and physical health consequences. The trauma might include the divorce of a parent or death of a close contact, Spikes said.
While men and women in the study reported similar levels of trauma, the men didn't experience vascular complications. Women tend to be exposed to different forms of trauma, so their reactions may be more chronic, the new research revealed.
'Evidence shows that girls are more likely to be exposed to sexual abuse, whereas boys are more likely to report physical abuse,' according to the study. 'Findings suggest that men and women have disparate clinical CVD (cardiovascular disease) outcomes such that men have an earlier age onset of CVD whereas women experience higher CVD mortality in adulthood.'
The study also found that 'women experience a greater burden of cumulative stress than men,' and it's possible that exposure to traumatic childhood events 'may prove more consequential for cardiovascular risk for women than men.'
Spikes attributed the increased stress of Black women to their tendency to be single moms supporting their families with wage disparities from their male and white counterparts. 'It places them in a prone position to be disproportionately impacted by various stresses.'
For balanced comparisons, the men and women in the study had the same marital status, education, and income levels, with almost half the participants making less than $25,000 annually. Participants from both sexes also had similar levels of blood pressure, glucose, triglycerides, diabetes, and hypertension.
Spikes worked with researchers from MECA, including cardiologists and psychologists, some of whom were involved in the original study. Among them, MECA Director Herman Taylor said the new research is another example of how the intense challenges Black people tend to face, including childhood trauma and deprivation, have health consequences.
'In general, it suggests that it's so important for people, especially women, to focus on their lifestyle and make adjustments now so they can reduce their risks,' said Taylor, a cardiologist, professor at Morehouse School of Medicine and director of its Cardiovascular Research Institute.
Among the findings of the new study, the higher proportion of mistreated children in Black communities, compounded by negative social stressors, may increase their risks for resorting to unhealthy coping mechanisms that can lead to cardiovascular disease.
Researchers hope the results of the latest study will convince clinicians to consider childhood trauma and other psychosocial stressors among more typical clinical assessments such as checking blood pressure, lipid levels, and lifestyle behaviors when determining a patient's risk of heart disease and how to help reduce it.
Clinicians, particularly primary care providers, should better understand the cardiovascular risks of African American women who come to their practice, especially if their blood pressure is borderline, Spikes said. She added that clinicians should refer such patients to mental health therapists.
Taylor agreed. 'I think it's important, and research and clinical experience repeatedly show the close relationship between state of mind and heart health. So much of mental health is communicated into the heart and the vascular systems. Life stressors and mental health challenges … can have important implications for your overall health, including heart health.'
He explained that doctors ask their patients about their 'medical, family, and what we call 'social history,'' to help judge disease risk. 'Telisa's work suggests knowing about a history of adverse childhood events — trauma, personal loss, even abuse — could be just as important to the prediction of disease.'
Taylor believes that one of the lessons learned from the latest research should be that all patients, even young ones who seem healthy, may have experienced a trauma earlier in life that affects their health later on.

Deadly NYC Legionnaires' disease outbreak fueled by negligence, lawsuit says
Civil rights attorney Ben Crump has filed lawsuits against two construction companies over what he called a "completely preventable" outbreak of Legionnaires' disease that has killed five people and sickened more than 100 others in New York City. Legionnaires' disease is a severe pneumonia caused by a type of bacteria called Legionella, which grows in warm or hot water, according to the Centers for Disease Control and Prevention. An outbreak of the disease, which began on July 25, has been clustered across five zip codes in Central Harlem. The city health department said the outbreak is linked to cooling towers, heat exchangers that use fans and water to cool down buildings. On Aug. 14, health officials confirmed that 12 cooling towers at buildings including NYC Health + Hospitals/Harlem tested positive for the Legionella bacteria. Crump and other attorneys filed complaints on behalf of two construction workers who were hospitalized with Legionnaire's disease in July after working near the hospital in Harlem, according to a news release. Crump said the legal team has also filed a notice of claim and intend to sue the city as well. "It is believed that the cooling towers at Harlem Hospital were filled with rainwater after several large July storms," the release said. "The water was left untreated, which permitted bacteria to spread causing workers at the site to become sick." Construction companies, city accused of negligence Crump accused Skanska USA Building, Inc., Rising Sun Construction LLC and the city of negligence at a news conference on Aug. 20, announcing the lawsuits. The attorneys said the construction companies were put on notice about the possibility of Legionella bacteria through bulletins after the storms, but failed to take action to keep those working near the hospital safe. "When corporations cut corners, tragedies like this happen. Preventable tragedies, unnecessary tragedies," Crump said. Crump said the lawsuit is seeking not only compensation for the workers but also accountability and answers about why this outbreak occurred in Harlem — a historically Black neighborhood in Upper Manhattan. Skanska and Rising Sun did not immediatedly respond to a request for comment from USA TODAY. When asked about Crump's claims about the source of the outbreak, a spokesperson for the city's health department said the investigation is ongoing. "Molecular testing may help us determine which cooling tower — or cooling towers — were the source of the bacteria in the Central Harlem cluster," spokesperson Chantal Gomez said in a statement. "The Public Health Lab is still determining a match through DNA sequencing and we expect final results soon.' Electrian describes gasping for air while hospitalized with Legionnaire's Nunzio Quinto, a union electrian who worked at a ground-up construction of the NewYork City Public Health Laboratory, a 10-story facility adjacent to the hospital complex, said he thought he had food poisoning when he first started feeling lethargic in late July. Quinto said his family took him to the hospital, where he was immediately diagnosed with Legionnaire's disease. He suffered breathing problems, pain and internal bleeding during a five-day stay in the hospital, but said his coworkers weren't notified of his illness. "I want answers to what's going on. I can't have a safe place to work? This is New York City," Quinto said at the news conference. Contributing: Thao Nguyen

How does Legionnaires' disease spread? What to know about NYC outbreak
NEW YORK − Health officials are still finding cases in one of the city's largest Legionnaires' disease outbreaks in years as they continue monitoring Harlem cooling towers suspected of sickening more than a hundred people. On Aug. 19, New York City health officials identified a fifth person died before mid-August from the central Harlem outbreak of Legionnaires' disease, which is a severe type of pneumonia. Since the outbreak began in late July, 108 people have been identified as sickened, according to the New York City health department. The outbreak is concentrated across five ZIP codes in central Harlem, a historically Black neighborhood in Manhattan. New cases continue to decline as officials remediate cooling towers suspected to harbor the Legionella bacteria that causes the disease. When was the last large Legionnaires' outbreak in NYC? The health department identifies cases each year, sometimes resulting in death. The city saw its largest recent outbreak in 2015. Then, 138 cases and 16 deaths were linked to a single cooling tower in the South Bronx, just across the Harlem River from the Harlem neighborhood. A more recent outbreak in 2022 in the Bronx's Highbridge neighborhood saw 30 people sickened, a city health department report said. Decades earlier, a large outbreak in Pennsylvania gave Legionnaires' disease its name. In 1976, an outbreak at an American Legion veterans organization state convention in a Philadelphia hotel infected 180 people and killed 29. How does Legionnaires' disease spread? The bacteria − found naturally in freshwater − grows in warm or hot water, according to the Centers for Disease Control and Prevention. The disease doesn't spread between people, but from mist containing bacteria that people inhale, city health officials said. Without maintenance, water systems, such as hot tubs, cooling towers, hot water tanks or big plumbing systems give the bacteria ideal places to grow. CDC estimates nine in 10 outbreaks were caused by preventable problems with effective water management. In New York, officials suspect a dozen cooling towers, used atop 10 larger buildings to control the temperature of cooling systems using fans and water as heat exchangers, caused the current outbreak. The cooling towers sprayed mist containing from the tops of buildings. Legionnaires' disease doesn't spread by drinking water, or from cooled air from air conditioners. Window AC units, ubiquitous on many buildings in New York, also aren't a risk for bacterial growth, since they don't use water to cool the air. City health officials have sampled and tested water from the cooling towers and treated affected buildings in the five ZIP codes (10027, 10030, 10035, 10037 and 10039). What are Legionnaires' disease symptoms? Most people exposed to the bacteria don't develop Legionnaires' disease. The risk to most people in central Harlem ZIP codes is low, but people who live or work in the area and have flu-like symptoms are urged to seek care right away, city health officials said in an Aug. 6 notice to residents. As a severe form of pneumonia, symptoms include fever, chills, muscle aches and cough, city health officials said. People can also get headaches, fatigue, loss of appetite, confusion or diarrhea. Symptoms develop between two and 10 days after exposure, but it can be up to two weeks. People at higher risk include those ages 50 and older, smokers, have chronic lung disease and have weakened immune systems from a condition or medication. Possible complications can include lung failure and death, with about one in 10 people who get sick dying from the disease due to complications from illness, CDC said. The disease is easily treatable with antibiotics. If people develop symptoms, they should seek medical care right away. What is risk ahead? With hotter, more humid temperatures in a warming climate, Legionnaires' disease is a growing health concern. CDC data shows the condition is becoming more common in recent decades. In New York, outbreaks tend to oscillate between predominantly lower income Black and Latino neighborhoods, a former health official previously told USA TODAY.

Americans spend less time reading for fun and more time on screens: Study
Fewer Americans are opening a book for fun each day, with reading for pleasure in the United States down 40% over the past 20 years, a new study finds. Researchers from University College London and the University of Florida analyzed surveys from more than 230,000 Americans aged 15 and older between 2003 and 2023, tracking their daily reading habits. Results, published in the journal iScience on Wednesday, showed the share of people who picked up a book, magazine or e-reader every day dropped about 3% per year. Reading with children was also rare, the study found, with only 2% of adults reporting doing so on average every day. However, those who did read spent more time doing so, averaging more than 90 minutes daily. "For me, one of the most important takeaways of this study is awareness of how little reading for children is happening," Jill Sonke, one of the study's lead authors as well as director of research initiatives and a research professor at the University of Florida Center for Arts in Medicine, told ABC News. "As a mother, reading to my children was a really important time for bonding as well as for relaxation and for stimulating my children's interest in reading and their imagination and creativity." The study also found that reading declined more sharply among Black Americans, those with less education or lower incomes, and people in rural areas, with gaps widening over the 20-year study period. The researchers speculated that the drop is likely tied to the rise of digital media, including social platforms, streaming and online browsing. "There's a correlation between time spent on digital media and reductions in reading time," Sonke said. "It does seem logical that the ways in which digital media compete for our time would be a factor in these declines in reading." The auhtors cautioned that less reading could affect health, well-being and literacy. Reading has been linked to stronger language skills, reasoning and empathy, they said. "I think it's important for people to understand that reading for pleasure is actually a health promoting activity," Sonke said. "We know that participating in the arts is a health behavior because it statistically results in improved health outcomes including well-being, social cohesion, mental health." The study authors say that national strategies often focus mainly on children. The authors suggested that adult reading habits also deserve attention, especially given their impact on health and well-being. The National Literacy Trust, an independent charity based in London that promotes literacy, advises setting aside 10 minutes before bed, carrying a book or e-reader during commutes and making reading a shared family activity. Even small changes can help bring reading back into daily life, the group notes.
