Only 13 percent completed all recommended tests over three years
In the years after childbirth, thousands of women in New York City are living with diabetes that goes largely unwatched — not because they are indifferent to their health, but because the systems meant to care for them were not built with their lives in mind. A study of nearly 5,600 postpartum women found that only one in eight received the blood sugar monitoring their condition requires, with the burden falling most heavily on Black mothers and those raising multiple children. The findings are less a medical curiosity than a mirror held up to the quiet inequities embedded in how healthcare is delivered — and to whom.
- Only 13% of women diagnosed with postpartum diabetes completed all six recommended A1C tests over three years, leaving the vast majority without adequate monitoring of a condition that can silently damage the heart, kidneys, and nerves.
- Non-Hispanic Black women were 10% less likely to receive timely follow-up care, a disparity researchers trace to residential segregation, uneven clinic access, and provider bias — structural forces that no individual reminder can fix.
- Motherhood itself became a medical obstacle: women with more children faced longer delays and lower monitoring rates, as the relentless demands of caregiving crowded out time for their own health.
- In a striking reversal of expectation, Medicaid enrollees outperformed those with private insurance — 14% more likely to receive early testing — suggesting that targeted outreach and expanded coverage can meaningfully move the needle.
- Researchers are calling for systemic redesign: childcare at clinic visits, flexible scheduling, appointment reminders, and paid leave policies that treat a mother's medical care as a legitimate claim on her time.
A New York City study tracking more than 5,500 women who developed diabetes after childbirth has revealed a stark failure of follow-up care: only 13 percent received all six biannual A1C tests recommended over a three-year period. The median wait before a first follow-up test exceeded five months after diagnosis — time during which uncontrolled blood sugar quietly raises the risk of heart disease, kidney damage, and nerve disorders.
The research, published in BMJ Open Diabetes Research & Care, drew on birth certificates, hospital records, and a citywide A1C registry. The cohort was diverse, with roughly equal shares of Hispanic and non-Hispanic Black women, most in their thirties, the majority on Medicaid, and more than half with a history of gestational diabetes — a known precursor to type 2 diabetes.
The monitoring gaps were not distributed equally. Non-Hispanic Black women were 10 percent less likely to receive timely testing and showed lower overall monitoring rates than non-Hispanic White women, a pattern researchers attribute to residential segregation, clinic scarcity in certain neighborhoods, and provider bias. Women with more children also fared worse, their appointments crowded out by the demands of caregiving.
One finding cut against the grain: Medicaid enrollees were 14 percent more likely to receive early testing than those with private insurance, suggesting that deliberate policy — outreach programs, expanded postpartum coverage — can make a measurable difference.
The researchers argue that closing these gaps will require more than reminders. Healthcare systems must be restructured around the reality of motherhood: childcare at appointments, flexible scheduling, and leave policies that make space for women to tend to their own health. The problem, the data makes clear, is not individual neglect — it is a system that was never fully designed for the people it is meant to serve.
A New York City study tracking thousands of new mothers has uncovered a troubling pattern: most women diagnosed with diabetes after childbirth are not receiving the blood sugar monitoring their doctors recommend, and the gaps fall hardest along lines of race and family size.
Researchers examined medical records from 5,590 women who developed diabetes in the years following delivery between 2009 and 2016. They looked at whether these women received regular A1C tests—the standard measure of long-term blood sugar control—over a three-year period. The guidelines are clear: testing should happen at least every six months. The results were stark. Only 13 percent of the women completed all six recommended tests over those three years. One in five managed five of the six. The median time before a woman received her first follow-up test was more than five months after diagnosis.
The consequences of this gap are not abstract. Uncontrolled diabetes in the years after pregnancy increases the risk of heart disease, kidney damage, and nerve damage. For women already managing the demands of new motherhood, missing these tests means missing the chance to catch problems early, when intervention is simpler and more effective.
The study, published in BMJ Open Diabetes Research & Care, drew on birth certificates, hospital records, and a mandatory New York City A1C registry to build its picture. The women in the cohort were diverse—about 31 percent identified as Hispanic, 31 percent as non-Hispanic Black, and the rest as other races and ethnicities. Most were in their thirties when diagnosed. More than three-quarters relied on Medicaid. Over 80 percent were overweight or obese at the start of pregnancy. More than half had experienced gestational diabetes during pregnancy, a condition that often foreshadows type 2 diabetes later.
But the monitoring gaps were not evenly distributed. Non-Hispanic Black women were 10 percent less likely to receive an early first follow-up test and showed an 8 percent lower rate of regular monitoring over time compared to non-Hispanic White women. Black Hispanic women showed similar patterns. The researchers point to structural causes: residential segregation that limits access to clinics, fewer healthcare facilities in some neighborhoods, and provider bias that can shape the quality of care offered.
One finding stood out as encouraging. Women covered by Medicaid had better outcomes than those with private insurance or other government coverage. They were 14 percent more likely to get an early first test and showed higher overall monitoring rates. This suggests that the problem is not inevitable—that policy choices matter. Medicaid's outreach programs and expanded postpartum coverage appear to be working.
Motherhood itself emerged as a barrier. Women who had given birth before were less likely to receive timely monitoring and experienced longer delays before their first test. The researchers suggest the obvious culprit: the demands of caring for multiple children make it harder to attend appointments. They recommend that healthcare systems respond by offering childcare during visits, scheduling flexibility, appointment reminders, and paid leave policies that allow mothers time for their own medical care.
The study has limits. It focused on New York City and included only women already connected to the healthcare system enough to receive at least one A1C test. Some women may have moved, sought care elsewhere, or never received a formal diagnosis. Still, the picture is clear: a large share of women with postpartum diabetes are falling through the cracks in follow-up care, and the system is not reaching those who face the most obstacles. Fixing this will require not just individual reminders but structural change—insurance policies, clinic hours, childcare access, and a healthcare system designed with the reality of motherhood in mind.

Why does it matter so much whether these women get tested every six months versus, say, once a year?
Because diabetes is progressive. You can feel fine and have no symptoms while your blood sugar is slowly damaging your heart, kidneys, and nerves. The A1C test catches that damage early, when you can still reverse course with medication or lifestyle changes. Miss those windows, and you're looking at complications that are much harder to treat.
The Medicaid finding is interesting—usually we hear that Medicaid patients get worse care. What's different here?
Medicaid programs often have built-in outreach and care coordination, especially for postpartum women. There are case managers, reminder systems, and continuity of coverage. Private insurance can be more fragmented. And Medicaid explicitly covers postpartum care for a longer window. It's a reminder that sometimes the safety net actually works when it's designed to.
The racial disparities—are those about insurance, or something else?
Both. But the study controlled for insurance and still found the gaps. That points to structural racism in healthcare itself. Where clinics are located, whether providers listen to Black women's concerns, whether appointments are offered at times that work for their lives. It's not one thing you can fix with a policy memo.
What strikes you most about the mothers with multiple children falling behind?
That it's so predictable and so preventable. We know motherhood is exhausting. We know childcare is expensive and hard to find. Yet the system acts surprised when women can't make appointments. The solution isn't to tell mothers to try harder. It's to build healthcare around the reality of their lives.
Do we know what happens to these women long-term?
Not from this study. But we know from other research that unmonitored diabetes leads to more hospitalizations, more complications, earlier disability. These are women in their thirties and forties. We're potentially looking at decades of preventable illness.
