CHEYENNE, Wyo. – Self-control is critical to developing healthy adult behaviors, and researchers studying willpower in children say how kids want to be perceived by peers may be just as influential as a child's natural traits or abilities.

Using the classic "marshmallow test" that allows children given one marshmallow to eat it immediately or wait until a second marshmallow is provided, researchers found that kids who wanted approval from their social group were more likely to exercise self-control when deciding whether or not to eat the marshmallow.

Researcher Sabine Doebel at the University of Colorado says it's similar to when adults decide to lose weight or quit smoking and find they're more likely to succeed if they hang around with a group of friends trying to achieve the same goal.

"So what we found is that when children were told that their group waited for two marshmallows, they themselves were able to wait longer," she notes.

The study included 100 preschoolers between the ages of three and five. Doebel says the findings are important because they show that self-control isn't just about abilities, or something that you have or don't have.

She says learning to practice self-control in key developmental years is important because it strengthens neural connections associated with the skill and makes it easier to practice throughout life.

"We study self-control because it's just so important in our lives," she says. "Whether or not we're going to eat that second piece of cake, whether or not we're going to study hard for that exam, it comes in everywhere in our lives and so it's important to understand how it develops."

Doebel says the study's findings run counter to prevailing assumptions that self-control is shaped by nature, and instead shows it can also be cultivated in children and even adults.

As pandemic-era protections were lifted a new report showed the number of children on Medicaid has varied widely between states, with Maryland doing better than most.

The Georgetown University report said nationwide, more than 4 million fewer children were enrolled in Medicaid and the Children's Health Insurance Program at the end of last year compared to spring 2023, before the expiration of continuous coverage. The report estimated in 70% of cases, children's coverage was canceled for procedural reasons such as difficulty navigating the state's website, reaching a person via a help line, or not receiving renewal notices.

Joan Alker, executive director of the Georgetown University Center for Children and Families and the study's co-author, said states need to improve outreach to help avoid disenrollment because of red-tape reasons rather than being ineligible.

"Some states chose to go very slowly and carefully and redo their entire eligibility system so that it worked better," Alker acknowledged. "But other states really doubled down and they moved very quickly to disenroll children, even though many of them likely remain eligible."

In Maryland, the number of kids with coverage declined 3% or nearly 20,000.

The Maryland Children's Health Program offers free as well as low-cost health insurance coverage for children under 19, and income eligibility for children is much higher than for adults. The report noted new programs in some states are offering multiyear continuous coverage to young children.

"A significant number of states are making a shift in their policy to offer continuous coverage for young children," Alker pointed out. "In most cases, from birth to age 6, in a few cases to age 3 or 5. And this is a really terrific breakthrough."

Maryland is not among the 12 states to develop a multiyear coverage program but the District of Columbia has.

Medi-Cal has dropped several hundred thousand low-income children from the health insurance rolls since April 2023, according to a new report from Georgetown University.

The data show a net drop in children's Medi-Cal enrollment of 200,000 kids between April and December of last year, as the state started redetermining participants' annual eligibility - which had been paused to ensure continuous coverage during the pandemic.

Mayra Alvarez, president of the Children's Partnership, said another 100,000 have been dropped this year.

"Some 80% of the people that lose coverage in California are losing it for procedural reasons," said Alvarez, "not because they're not eligible but because their paperwork didn't make it to the county, or they waited too long on the line and got frustrated and had to hang up, or they moved and the letter never even reached them."

The state of California has made a massive outreach effort to keep those who are eligible covered.

More than half a million children, half of California's kids, depend on Medi-Cal. And three quarters of them are children of color.

It is unclear how many kids who lost Medi-Cal were later enrolled in private coverage.

Joan Alker is a co-author of the report, and executive director of the Center for Children and Families at Georgetown University. She said gaps in coverage can lead to long-term negative impacts.

"Kids are going to miss out on those well-child visits, they're going to miss out on getting the medications they need," said Alker, "be it an inhaler for their asthma or an ADHD medication. And that really sets them back, both in their health and their success in school."

A few years ago, California lawmakers passed a requirement for continuous coverage in Medi-Cal for children ages zero to five.

Alvarez said she is urging them to follow through and allocate $10 million in the next state budget to fulfill this mission.

After Texas, a new report shows Florida has seen the second-largest decline in the number of children enrolled in Medicaid and the Children's Health Insurance Program.

Of the 4.16 million fewer children enrolled in Medicaid and CHIP nationally, Florida accounts for nearly 600,000 enrollment declines - according to a report by Georgetown University's Center for Children and Families, tracking the Medicaid unwinding since COVID-related coverage protections were lifted.

Alison Yager, executive director with the Florida Health Justice Project, said it's more like a crisis has been unfolding in Florida - and they've long been sounding the alarm.

"This, at its most extreme, can be a question of life or death, really," said Yager, "and short of that, we're seeing far too many families having to now scramble to figure out what's going to change in their monthly budget so they can now pay for whatever medication their kids require."

Yager cautioned that even if families qualify for one of Florida's KidCare programs, there are gaps in coverage.

Going without insurance, even briefly, can cause people to delay seeking care and leave them financially vulnerable when they do.

In February, the state sued the Center for Medicaid Services to stop them from enforcing 12 month continuous eligibility in the state's CHIP program.

The report is based on administrative data from the states to the Centers for Medicare and Medicaid Services.

Joan Alker - executive director of the Center for Children and Families at Georgetown - said Texas, Florida, Georgia and California accounted for half of the total national decline in kids with health insurance.

"This is a real crisis in these states for families whose children rely on Medicaid, but also for the providers that serve them - pediatricians and clinics," said Alker. "The system is really getting shaken up."

An April survey by KFF reveals that almost one fourth of adults who were removed from Medicaid - the program for low-income individuals - after pandemic-related protections ended last spring, now report being uninsured.
