Geographic Gaps in Maternity Care Cost Lives
Analysis of 14,772,210 live births revealed that counties designated as maternity care deserts faced significantly higher maternal mortality rates than those with full access to care. Desert counties showed a 36% higher risk for maternal death and a 26% increased risk for pregnancy-related mortality.
METHODOLOGY:
The analysis included county-level data from the CDC Wide-Ranging Online Data for Epidemiologic Research database from January 2018 to December 2021.
A total of 14,772,210 live births were analyzed across four county categories: desert (n = 720,858), low access (n = 708,668), moderate access (n = 431,188), and full access (n = 12,911,496).
Researchers restricted the study population to individuals aged 15-44 years to enhance accuracy and mitigate misclassification.
Primary outcome measures included maternal mortality rate per 100,000 live births, with pregnancy-related mortality rate as a secondary outcome.
TAKEAWAY:
Desert counties showed significantly higher maternal mortality rates than full-access counties (32.25 vs 23.62 per 100,000 live births; absolute risk difference, 8.62; 95% CI, 4.63-12.61; adjusted incidence rate ratio [IRR], 1.36; 95% CI, 1.21-1.54).
Desert counties also demonstrated higher pregnancy-related mortality rates than full-access counties (43.82 vs 34.72 per 100,000 live births; absolute risk difference, 9.10; 95% CI, 4.28-13.93; adjusted IRR, 1.26; 95% CI, 1.13-1.41).
No significant differences in maternal or pregnancy-related mortality rates were found between low-access or moderate-access counties compared to full-access counties.
IN PRACTICE:
'Maternity care deserts are associated with significantly higher rates of adverse maternal outcomes because limited access to skilled practitioners delays timely interventions during critical stages of pregnancy and childbirth,' the authors of the study wrote.
SOURCE:
This study was led by Tetsuya Kawakita, MD, MS, from the Department of Obstetrics and Gynecology at the Macon and Joan Brock Virginia Health Sciences at Old Dominion University in Norfolk, Virginia. It was published online in Obstetrics & Gynecology.
LIMITATIONS:
Fatalities temporally linked to pregnancy, such as homicide, suicide, or drug overdose, were often coded as external causes on death certificates and may have been excluded from the CDC pregnancy-related mortality classification. The surge in mortality during the COVID pandemic may have accentuated existing disparities. The cross-sectional analysis precluded causal inferences regarding relationships between maternity care access and maternal outcomes. The definition of maternity care practitioners did not include family physicians who might have provided obstetric services in rural areas. Additionally, the maternity care access measure did not capture the intra-county spatial distribution of services, potentially masking access barriers in geographically extensive or sparsely populated rural counties.
DISCLOSURES:
This study received support from the Eastern Virginia Medical School Junior Clinical Investigator Program.

How Trump's tax bill could affect the healthcare industry
The tax bill recently signed by President Trump represents the largest cut to federal healthcare spending ever, according to several experts, and could leave as many as 12 million Americans without insurance by 2034. That's according to the Congressional Budget Office, but some think tanks and analysts suggest that number could be lower. In June, Jefferies analysts estimated the impact would result in between 6 million and 7 million uninsured. The bill does not extend subsidies for the Affordable Care Act market health plans introduced during the COVID-19 pandemic, which will raise premiums for some individuals, and removes eligibility for legal immigrants. The bill also takes away bridge coverage from job losses or other life-altering events, which could further increase the cost and burden on some individuals. In addition, the bill would cut a significant amount of funding — some estimates show up to $1 trillion — from Medicaid funding through 2034. That includes state taxes that are used to help increase the amount of Medicaid dollars health providers receive, often described as underfunding since it doesn't reimburse hospital costs dollar for dollar. Read more: What is a healthcare FSA? A way to save on medical costs. In 2024, the US spent $1.9 trillion on healthcare, or about 27% of the total federal budget. That includes Medicare and Medicaid, with the latter accounting for 8% of that total, according to KFF. On Monday, Jefferies analysts said that while the bill is likely to have the most impact on healthcare providers such as doctors and hospitals, the delayed timeline for implementation provides enough of a cushion. "Near-term, we remain positive on the fundamental outlook for [healthcare] service providers given our belief that utilization trends remain strong, translating to continued volume/revenue growth. That said, given the phased or later implementation of many of these policies, we do not expect an impact on fundamentals until 2026," the analysts wrote.

Study finds 6% of Florida teens have handguns, a 65% increase over 20 years
Despite increased concerns about rising gun deaths among children, new research found that the number of teenagers who have handguns has gone up. The study, published Monday in the journal Pediatrics, found that Florida adolescent general handgun carrying increased by 65%, from 3.7% to 6.0%, from 2002 to 2022. Females, middle school-aged teens and white students were among the groups that most substantially contributed to the increase. "These findings indicate the need to specifically tailor earlier prevention strategies focused on handgun access and carrying toward female and middle school students, with ongoing attention to rural and male adolescents across racial and ethnic identities, who still have the highest prevalence of carriage after a 20-year period," the authors wrote. Researchers used data from the Florida Youth Substance Abuse Survey, a cross-sectional survey of Florida middle and high school students. In total, more than 700,000 student respondents were analyzed. Though general handgun carrying went up, carrying in school decreased by 60%, from 1.1% to 0.4%, according to the study. There was also a 39% decrease in favorable attitudes toward school carrying, the study found. The authors noted that both these decreases initially seemed contradictory, as school shootings have increased in the past 25 years. "Ongoing research should explore factors influencing regional and sociodemographic differences in these trends, such as the increases in school safety measures (eg, controlling access to buildings, requiring visitors to sign in, using security badges) or increases in the presence of security or law enforcement officers," the authors wrote. They also noted the study's limitations, including the reliance on self-reporting, which can introduce bias. Firearms are the leading cause of death among children and teenagers in the United States, with a steep increase in ages 15 to 19 starting in 2020. Nonfatal firearm injuries among children under age 18 also increased 113.1% from 2011 to 2021, another recent study found. A study published last month in JAMA Pediatrics found gun deaths among children rose in states with lax firearm laws, with certain states seeing a jump in pediatric gun deaths after amending their firearms restrictions. Meanwhile, in the states that had the most restrictive laws, deaths remained stable or, in some cases, there were fewer pediatric gun deaths.

Experts Reveal Surprising Reason You Should Never Work Out Before Bed
"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links." Daily exercise is part of a healthy lifestyle. According to the Centers for Disease Control and Prevention (CDC), adults should log at least 150 minutes of physical activity per week—that's about 20 to 30 minutes a day. And if you haven't gotten your workout in by nighttime, you might be tempted to sneak in some exercise before bed. Meet the Experts: Nicole Avena, M.D., research neuroscientist, expert in nutrition and diet, brain health and wellness; Angela Holliday-Bell, M.D., board-certified physician, certified sleep specialist, and host of The Art of Sleep; Aric Prather, Ph.D., sleep expert and co-developer of Headspace's Finding Your Best Sleep program. But experts say you should think twice: Working out at night could make it harder to fall asleep and stay asleep. And since sleep is crucial for health and wellness, are you really better off skipping exercise or sacrificing shut-eye? To find out, we asked experts if it's ever a good idea to work out before bed, the best type of exercise to do at night, the best time of day to work out, and more. Working out before bed won't cause problems for everyone. But many will find that vigorous exercise gives them a burst of energy, raises their body temperature, and disrupts their wind-down—making it harder to fall asleep, says Aric Prather, Ph.D., sleep expert and co-developer of Headspace's Finding Your Best Sleep program. When you do high-intensity exercise, your body experiences an increase in metabolic rate, adrenaline, blood pressure, and heart rate, and it takes time to return to your normal and relaxed state. 'This means if you were to exercise before you go to sleep, you run the chance of not allowing your body enough time to wind down,' says Nicole Avena, M.D., research neuroscientist, and an expert in nutrition and diet, brain health, and wellness. When your body isn't relaxed before bed, it's harder to fall and stay asleep. Working out can also increase your body temperature. 'And since a 1- to 2-degree drop in body temp is needed in order to transition to and maintain sleep, exercising before bed can hinder your ability to fall asleep,' says Angela Holliday-Bell, M.D., board-certified physician, certified sleep specialist, and host of The Art of Sleep. Plus, the endorphins released during exercise can be stimulating and make it harder to fall asleep. If you're going to exercise before bed, experts recommend sticking to low-intensity exercises. 'Activities like yoga or going on an evening walk can help to stretch and relax your muscles without spiking your adrenaline,' Dr. Avena says. These movements can improve your sleep by allowing your mind and body to relax while reducing stress. Dr. Holliday-Bell agrees that gentler exercises, like yoga or stretching, are ideal before bed. 'It's best to avoid exercises that are too strenuous. as they can cause the body temperature to be elevated too long, making it difficult to fall asleep,' she explains. The best time to exercise is whenever you can fit it in, says Prather. But research suggests that morning is a particularly great time to work out, says Dr. Avena. One 2014 study found that people who worked out in the morning slept longer, experienced deeper sleep cycles, and spent 75% more time in the most restorative stages of slumber (for both mind and body) than those who exercised later in the day. Research also suggests that people who exercise earlier in the day find it easier to stay focused and tend to make healthier food choices, says Dr. Avena. 'Starting your day with a workout can set a positive tone, making you more aware of your dietary choices throughout the day,' she explains. There's also the thought that working out in the morning boosts metabolism. One recent study found that early-morning activity—between 7 and 9 a.m.—could help with weight loss. Another study suggests that late-morning exercise could be more effective than late-evening exercise in terms of boosting the metabolism and burning fat. 'Being active in the morning improves my ability to concentrate, focus, and retain information throughout my workday,' Dr. Avena notes, anecdotally. And since studies have shown that exercise may help decrease overall stress levels and improve well-being, this makes sense. Exercise is thought to help you sleep better for several reasons, says Prather. First, exercise reduces stress. 'Stress is one of the biggest reasons why so many have chronic sleep problems, and getting regular exercise has been shown to be a reliable stress-buster,' says Prather. Second, regular exercise helps regulate your circadian rhythm—your internal clock. 'This stability makes [the] time we wake up and the time we get sleepy at night reliable,' Prather explains. Third, some evidence suggests that exercise can improve slow-wave sleep, which is the deepest sleep cycle and the one most often linked to restoration, he adds. Exercise can also cut down the time it takes for someone to fall asleep and reduce the number of times they wake up in the middle of the night, says Dr. Avena. 'Overall, it results in a deeper and more restful night's sleep if you give your body enough time to properly cool down before bed,' Dr. Avena says. Regular exercise is one aspect of good sleep hygiene, but it's not the only one. 'Be sure to create a supportive wind-down prior to bed and disconnect from work and other things that keep your mind buzzing at least an hour before you want to get to sleep,' Prather says. Avoiding alcohol a couple hours before bed and cutting caffeine consumption by early afternoon will also help you get better sleep, he notes. Keeping a consistent schedule is also key when it comes to getting good sleep—meaning you should try to wake up and go to sleep around the same time each night. 'Having a consistent and non-stimulating bedtime routine can help protect against stress and make it easier to fall asleep,' says Dr. Holliday-Bell. 'Sleeping in a bedroom space that is dark, quiet, cool, and clutter-free can lead to better sleep as well.' Getting natural light exposure first thing in the morning also helps to reinforce your circadian rhythm, making it easier to wake up and fall asleep. Although research shows that working out before bed can disrupt your sleep schedule, any exercise is better than no exercise, says Dr. Holliday-Bell. 'Try not to exercise within 3 to 4 hours of your bedtime,' she says. 'However, if that is the only time you can be physically active, it is still recommended that you do so, just be mindful of having a strong bedtime routine.' And pay attention to how your pre-bed workouts are affecting you. If you're struggling to fall or stay asleep, try switching to low-impact or low-intensity exercise before bed. Or move your high-intensity workouts earlier in the day, says Dr. Avena. You Might Also Like Can Apple Cider Vinegar Lead to Weight Loss?
