    State Choices, Unequal Access: Policies Shaping Reproductive Health Care Across the United States — 2026-06-16
    Jun 16 2026
    ## Short Segments Out-of-pocket costs for long-acting reversible contraception are rising, despite ACA mandates. Today, we'll explore why some insured individuals still face unexpected expenses for IUDs and contraceptive implants. Later, we'll dive into how state policies are shaping reproductive health care access across the U.S. Let's start with the headline: Unexpected Costs for Contraception Under ACA . Despite the Affordable Care Act's requirement for free contraception coverage, many individuals with employer-sponsored insurance plans are still paying out-of-pocket for long-acting reversible contraception, like IUDs and implants. A study published in the journal Contraception highlights that the proportion of people paying nothing for these contraceptive methods has decreased since 2014. This is significant because these methods are among the most effective forms of birth control, yet unexpected costs can deter their use. For instance, Erica M., a 23-year-old with employer insurance, faced unexpected bills for an IUD, despite ACA provisions. The study suggests that high-deductible health plans may contribute to these costs, impacting nearly half of privately insured Americans. As a result, the financial burden could influence contraceptive choices, potentially leading to less effective birth control use. ## Feature Story State policies are creating unequal access to reproductive health care across the United States. Authored by KFF’s Alina Salganicoff, Ivette Gomez, and Usha Ranji, a recent article examines how these policies impact women's access to contraception, abortion, and maternity services. State decisions on Medicaid coverage, professional credentialing, and reproductive rights significantly influence the availability of these services. For example, Massachusetts, Vermont, and Rhode Island rank highest in the 2024 State Scorecard on Women’s Health and Reproductive Care, while Mississippi, Texas, Nevada, and Oklahoma rank lowest. These rankings are based on 32 measures of health care access, quality, and outcomes. Deaths from all causes among women of reproductive age are highest in southeastern states, with preventable causes like pregnancy complications and substance use contributing significantly. Since the 2022 overturning of Roe v. Wade, access to reproductive care has faced additional challenges. While organizations and individuals continue to support sexual and reproductive health rights, the anti-abortion movement remains active, further complicating access. In 2025, the landscape of reproductive health care access is marked by resilience and ongoing struggle. State policies play a crucial role in shaping this landscape, affecting millions of women across the nation. As we look ahead, understanding these policy impacts is essential for addressing disparities and improving access to reproductive health care. Listeners should watch for changes in state policies and their implications for reproductive health services.

    Jun 14 2026
    ## Short Segments People taking GLP-1 weight loss drugs like Ozempic are moving less, according to new research. Middle-aged Americans are facing a crisis of loneliness and declining health. And a surprising study finds that sugar-free diets might not be as healthy as they seem. Later, we'll explore how telehealth companies are influencing insurance coverage for obesity drugs. People taking GLP-1 weight loss drugs like Ozempic started moving less. Researchers have found that individuals on popular weight-loss medications such as Ozempic, Wegovy, Mounjaro, and Zepbound are experiencing a decline in physical activity. Despite shedding pounds, Fitbit data reveals a drop in daily step counts and exercise levels. This trend raises concerns because these drugs can reduce muscle mass along with fat, potentially impacting long-term health and strength. The findings suggest that while these medications are effective for weight loss, they may inadvertently discourage other healthy habits, highlighting the need for a balanced approach to weight management. Why middle age is becoming a breaking point in the U.S. A new international study highlights a troubling trend among middle-aged Americans, who are reportedly lonelier, more depressed, and experiencing worse memory and health compared to previous generations. Researchers attribute these issues to growing financial strain, weaker social supports, and chronic stress. This demographic is increasingly seen as a pressure point, with the U.S. falling behind other wealthy nations in terms of midlife well-being. The study underscores the need for targeted interventions to address these challenges and improve the quality of life for middle-aged individuals. Scientists found a surprising problem with sugar-free diets. A recent study suggests that completely eliminating sugar from the diet may have unintended negative effects. Mice on a sucrose-free, low-fat diet showed worse blood sugar control, increased inflammation, and signs of fatty liver compared to those consuming some sucrose. These findings indicate that a balanced diet and a healthy gut microbiome are crucial, rather than focusing solely on cutting out sugar. The research challenges the common perception that sugar-free diets are inherently healthier, emphasizing the importance of moderation and balance in dietary choices. ## Feature Story Want obesity drugs covered by insurance? Telehealth companies have a big say. Telehealth companies are playing a pivotal role in the coverage of obesity drugs by insurance providers. Employers are increasingly relying on these companies to offer lifestyle support for individuals taking GLP-1 medications, such as Zepbound, to enhance weight loss success. However, there's a catch: employers also expect telehealth providers to help limit spending on these costly drugs. This dual role creates a complex dynamic where patients like David Davis, a power plant worker from California, find themselves navigating a maze of requirements to get their prescriptions approved. Davis's experience with Vida Health, a telehealth company, highlights the frustration many face as they jump through hoops to access necessary treatments. The involvement of telehealth companies in this process reflects a broader trend in the healthcare sector, where digital health entities are capitalizing on the popularity of GLP-1 medications. As these drugs become more prevalent, the pressure on telehealth companies to manage costs while providing effective support is likely to increase. This situation underscores the evolving landscape of healthcare delivery and the growing influence of telehealth in shaping treatment accessibility. As the demand for obesity drugs continues to rise, the role of telehealth companies in determining insurance coverage will be a critical area to watch.
