Combined Effects of Maternal Obesity and Diabetes Raise Autism Risks

While the incidence of autism spectrum disorder has increased in recent years, what’s behind it remains relatively mysterious and even controversial. But a major study could shed new light on some of the maternal health factors that may increase children’s risk of developing the condition.

Autism is a neurodevelopmental disorder marked by difficulties with communication and social interaction as well as repetitive or obsessive behaviors. The range and severity of symptoms can vary widely.

The study, which was released Friday and appears in the February issue of the journal Pediatrics, followed almost 3,000 children who visited the Boston Medical Center between 1998 and 2014. It used electronic health records to track whether these children were diagnosed with autism, along with factors like the mother’s pre-pregnancy weight and whether she had been diagnosed with diabetes before or during her pregnancy.

Though previous research has looked at the roles of maternal obesity and diabetes on autism risk, this study is the first to examine both the independent and combined effects of the two.

The researchers found that of the nearly 3,000 children in the study, about 100 were identified as on the autism spectrum.

They also concluded that obese women who contracted diabetes while pregnant — a condition known as gestational diabetes — were about three times as likely to have children with autism. Women who were obese and had diabetes before pregnancy were almost four times as likely. In addition, children with autism were more often boys, more often born before 32 weeks and more often had very low birth weight. Beyond being obese and diabetic, their mothers were also more likely to be older.

Having just one of the conditions, however, posed only a slight risk increase.

Overall, though, the risk was “substantially higher” when women had both, according to the study.

It “calls attention to the idea that maternal prenatal health and maybe even pre-pregnancy health may be important factors for autism — and may be important opportunities for protection from autism,” said study co-author Daniele Fallin, who chairs the department of mental health and directs the Wendy Klag Center for Autism and Developmental Disabilities at the Johns Hopkins Bloomberg School of Public Health.

The findings are important because, if doctors have a better sense of autism’s causes, they can try to reverse the current trend lines and stem its growth, Fallin said.

In 2010, the most recent year for which there’s data, about 1 in 68 children were estimated to have autism. That’s a contrast to 10 years prior, in 2000, when 1 out of 150 children were believed to have it. Experts say part of the growth likely is because people are simply getting better at recognizing and diagnosing the disease. But, according to the Centers for Disease Control and Prevention, the disorder is also probably occurring more often than it used to.

“The cost per family per year of having a child on the spectrum is enormous — therefore societal costs are enormous,” Fallin said. “If you can do anything to stem the tide of rising prevalence, or even drop the prevalence, then absolutely, you should. Not only individual families benefit, but society benefits.”

A different study published last year in the Journal of Autism and Development Disorders estimated that taking care of people with autism cost the country about $268 billion in 2015 — a figure that accounts for medical expenses, other kinds of caregiving and the decreased productivity both from people who care for autistic relatives and for adults on the spectrum.

If the increase in prevalence continues at its current rate, this expense will grow markedly, that study noted.

From a cost standpoint, then, the new research underscores the importance of preventing obesity and diabetes, said Paul Leigh, a professor of public health sciences at the University of California, Davis, who authored the autism cost study. Because of the autism tie, “there are more reasons to be worried about [obesity and diabetes], and to direct resources to removing this problem.”

The Pediatrics paper is significant, both for its findings and for its comprehensiveness in examining medical records from a large sample, said Alycia Halladay, chief science officer at the Autism Science Foundation. It suggests that if policymakers and insurers put more money into treating diabetes and obesity, the public as a whole could benefit, especially if that fuels a decline in autism cases.

“Instead of demonizing mothers with diabetes, we need to be using this as an opportunity to help them mitigate their risks as much as possible,” she said.

On June 4, a national nonprofit named the Equity in Infrastructure Project (EIP) – which aims to increase public construction contracting opportunities for small and historically underutilized businesses – held a day-long event in downtown San Francisco to rally supporters and build momentum to its cause.

It was attended by more than 100 individuals from public agencies, private firms, and other organizations committed to increasing contracting opportunities with governmental agencies, thereby creating more competition and lowering public costs.

The EIP event was held the Hyatt Regency San Francisco in conjunction with BuildIT, which aims to increase contracting opportunities for LGBT-owned businesses.

At the event, 16 entities signed the EIP pledge, vowing to take steps to increase public contracting opportunities in their spheres for small and historically underutilized businesses.

The pledge signees included Hub International, the Port of San Francisco, the San Francisco Public Utilities Commission, California High-Speed Rail Authority, the Port of Oakland, Robert Graham of Webcor Builders, Holder Construction, the Weitz Company, Sky Blue Builders, Hornblower, Swinerton, Luster National, Talson Solutions, Center for Community Wealth Building, and the Construction Contractors Alliance.

Following the workshop, BuildIT hosted a VIP evening reception honoring EIP, whose principals – Phil Washington, John Procari, and Rick Jacobs – accepted the award.

The event also set in motion the coalition’s efforts to implement recommendations from EIP’s “Procurement for Prosperity: A Playbook.”

The Playbook is a practical guide for public agency leaders and procurement and contracting practitioners to grow the capacity of small and first-time contractors, strengthen competition, and deliver better value for taxpayers.

Toks Omishakin, Secretary of the California State Transportation Agency (CalSTA), a long-time EIP supporter, also told attendees, “This is about commitment. This has been a life’s work. This is a tailwind moment.”

The event’s presenting sponsor was Hub International, one of the largest insurance brokerages in the nation, which was joined by partners Travelers Insurance and the State Compensation Insurance Fund.

After the pledge-signing ceremony, attendees participated in a workshop in which they examined the policies, practices, and programs needed to meet EIP goals, learned from practitioners, and identified next steps toward utilizing the Playbook.

Ingrid Meriwether, formerly of Merriwether & Williams Insurance Services (MWIS) and current president of Hub International’s Aligned Risk Management, MWIS, described the hard-fought lessons she and her MWIS team have learned over the last three decades administering contractor development programs (CDPs) for the City and County of San Francisco, Alameda County, City of Los Angeles, LA Metro, and other municipalities.

The CDPs help small and local construction firms win public infrastructure contracts with these government agencies. The program provides bonding assistance, contract financing, technical support, training, and other services to underrepresented businesses funded by public agencies who seek greater contracting participation with these firms.

Merriwether said programs like these “break down systemic barriers, create greater fairness, and save taxpayers money by enabling more competition. The contractor development programs have, cumulatively, over two decades, helped contractors access over $1 billion in bonding, supporting over $380 million in awarded contracts, and maintaining a loss ratio 250 times lower than the industry average – while saving participating municipalities more than $27 million in contracting costs as a result of enabling more competition.”

Rick Jacobs, EIP co-founder and co-chair urged attendees make plans to meet again in the near future “to continue building on this work, share progress on organizational commitments, and discuss how we can collectively advance the goals of the EIP pledge.”

The Oakland Museum of California (OMCA) opened “Mildred Howard: Poetics of Memory,” the first major museum survey of Bay Area artist Mildred Howard, on June 12.

The exhibition spans five decades of Howard’s influential work, bringing together immersive installations, found-object sculptures, archival materials, and new commissions that explore memory, identity, and power in American life.

Howard was born in San Francisco in 1945 and raised in the East Bay, where she went on to study Afro-Haitian dance, make and sell clothing, and experiment with collage and sculpture.

Her multimedia art practice emerged from these experiences, later becoming associated with West Coast conceptual art, San Francisco funk, and a vibrant community of artists like Oliver Jackson, Betye Saar, and Raymond Saunders. Since the 1970s, she has used found materials and family stories to explore memory—both individual and collective.

At OMCA, visitors enter “Poetics of Memory” through a series of intimate galleries featuring Howard’s early mixed-media pieces and sculptures, along with a large video projection of a number of her public artworks.

Together, they emphasize Howard’s interest in everyday objects as powerful carriers of individual and shared stories. Highlights include collages that remix images of the artist herself; found-object sculptures like The History of the United States with a few Parts Missing (2007) that address omissions in dominant narratives; and public works like “Locks and Keys for Harry Bridges” (2001) that transform urban space into a meditation on access and labor.

This culminates in a richly detailed “studio” environment, where works in progress, archival exhibition flyers, historic photographs of Howard and her community, postcards from fellow artists, and other materials offer insight into her creative process and daily life.

The exhibition then opens into a high-ceilinged, dramatically lit space that brings together Howard’s signature immersive installations. On one end, “Crossings” (1997/2026) – a field of hundreds of ceramic eggs leading to an ornate mirror – suggests cycles of birth, motherhood, and transition, while drawing on the emotional echoes of the Middle Passage. On the other end, “Blackbird in a Red Sky” (a.k.a. “Fall of the Blood House”) (2002) – a red glass shack bordered by a pond – also uses reflection and transparency to draw viewers into the work and prompt consideration of themes of identity and home.

Howard’s newest video installation, “Moving Stills” (2026), repurposes never-before-seen family footage she took as a teenager on a train trip to the American South. Projected onto cascading layers of translucent fabric that stretch across an entire gallery wall, the piece immerses viewers in a layered meditation on memory, migration, and time.

The “Mildred Howard: Poetics of Memory” exhibit will be on display through Oct. 11 at the Oakland Museum of California, 1000 Oak St., Oakland, CA 94612. Museum hours are Wednesday through Sunday, 11 a.m. to 5 p.m., with extended hours on Fridays to 9 p.m.

Starting July 1, the standard adult fare for the San Francisco Bay Ferry route between Richmond and San Francisco will increase to $5.20, up from the current $4.90.

Discounted fares for eligible passengers, including youth, seniors, people with disabilities, and Clipper START users, will rise to $2.60 from the current $2.40. Children under 5 will continue to ride for free.

The Oakland and Alameda routes will increase from $4.90 to $5.10, the South San Francisco route will go up from $7.40 to $7.60, and the Vallejo route will increase from $9.90 to $10.

The adjustments are part of a systemwide fare update approved by the agency’s Board of Directors, which is moving away from a flat 3% annual increase to route-specific pricing for the 2027 and 2028 fiscal years.

This fare update arrives as San Francisco Bay Ferry celebrates a historic May, transporting 301,270 passengers. The record-breaking figure represents an 8% increase over May 2025 and marks the third consecutive month of record-setting ridership.

Furthermore, it is the sixth month in a row that passenger numbers have exceeded pre-pandemic levels. Weekend travel has been a primary driver of this growth, with average weekend ridership seeing a 56% increase compared to pre-pandemic trends.

The agency states that the fare adjustments are necessary to ensure the long-term fiscal sustainability of public ferry services. By shifting to route-specific adjustments, the agency aims to offset rising operating costs while maintaining the high levels of service frequency and reliability.
