Troje for five -arms of American children is enrolled in Medicaid, and many experiences at the age of 18

According to the microsimulation model developed by scientists from Harvard Th Chan School of Public Health, at the age of three, three out of five American children enrolled in Medicaid or the health insurance for children (chip), and two out of five experienced a period of notification, developed by scientists from Harvard Th Chan School of Public Health. The first study, which estimates the cumulative insurance experience during full childhood, emphasizes the wide range of Medicaid and Chip, programs that have recently undergone significant changes in politics.

In July 2025, Centers for Medicare and Medicaid Services ceased to approve exemptions from section 1115 for many years of continuous public insurance among children. In the same month, the Federal Act on budget reconciliation was signed, which, according to the congressial forecasts of budgetary offices, will reduce Medicaid financing by $ 1 trillion and reduce registration by 10 to 15 million people. Our study is a valuable reference level for the understanding of which is long -term insurance protection in the US, can affect these broad changes. “

The fragmented data on claims related to health insurance and short periods of observation in national surveys hinder efforts to track child insurance in the US for a long time to solve these restrictions, scientists have joined the national national group, representative of the national group of children. Then scientists estimated the cumulative insurance results over 18 years in political conditions similar to those in 2015-2019, after expanding the insurance of the Act on inexpensive care, but before temporary policies introduced during the crisis in the field of public health Covid-19 in 2020.

Research estimates suggest that in their 18th birthday 61% of children enrolled in Medicaid and Chip, and 42% experienced gaps in the field of protection. Researchers also estimated that the disturbance of scope was more often in the United States that did not expand their medicaid programs. Among the children born in the field of Medicaid or Chip in unwavering states, 59% experienced uninsured periods, compared to 36% of their counterparts in the states of expansion. Comparing the higher levels of Medicaid and Chip eligibility, income between states, at the highest thresholds with the most restrictive thresholds, recorded the highest share in insurance disturbances among children covered by Medicaid or Chip at birth.

“The upcoming changes in Medicaid can affect a significant part of children and deteriorate significant insurance gaps,” said the elderly author Nicolas Menzies, a professor of global health and lecturer at the Center for Health Decision. “We are particularly worried about the explicit loss of eligibility for public insurance for non -spring children; the effects of inflammation through loss of parental insurance due to work requirements and greater eligibility controls; and cuts at medicaid level.”
