A recent extensive survey conducted by the Annenberg Public Policy Center (APPC) at the University of Pennsylvania sheds new light on American public knowledge regarding maternal health and its direct impact on infant outcomes. Despite widespread awareness of general pregnancy health fundamentals, the data reveals enduring gaps in detailed understanding, particularly concerning preconception alcohol avoidance and nuanced nutritional guidance during pregnancy. This large-scale, nationally representative study, conducted between April 14 and 28, 2026, among 1,639 U.S. adults, highlights a complex landscape of maternal health literacy that intertwines scientific evidence with public perception and behavior.
The study underscores a pronounced increase in awareness that maternal health habits before conception are consequential for infant well-being. Notably, 90% of adults recognize that taking care of one’s health before becoming pregnant profoundly affects infant health, a statistically significant rise from 86% in 2025. Among women of reproductive age, this awareness jumps to 86%, marking an 11-point increase from the previous year. These figures suggest that public health messaging around preconception care is beginning to resonate more effectively, potentially influencing healthier behaviors well before pregnancy is established.
Familiarity with health practices during pregnancy remains robust, with 93% of adults acknowledging that prenatal health decisions significantly affect fetal outcomes. This stable understanding aligns with consistent public health campaigns, which underscore the critical period of gestation in shaping lifelong health trajectories. Equally, 83% of adults correctly affirm the necessity of diabetes screening during pregnancy, reflecting a subtle yet important uptick in recognition likely linked to rising gestational diabetes incidence and associated neonatal risks observed in clinical epidemiology.
However, the survey reveals persistent uncertainties in specific maternal health recommendations. For instance, proper guidance on iron supplementation remains unclear, with only 40% of respondents understanding that daily iron supplements are medically advised solely for those who are anemic, while nearly a quarter mistakenly believe all pregnant individuals require daily iron intake. This misunderstanding has implications for clinical practice and public health, as excessive iron can induce adverse oxidative stress and gastrointestinal side effects. It indicates an urgent need for targeted communication clarifying iron’s role and individualized supplementation protocols during pregnancy.
Equally striking is the gaps in knowledge regarding gestational weight gain, a factor intricately linked to perinatal outcomes including preterm birth and fetal growth restriction. Just under half of the surveyed population correctly identifies the CDC’s recommendation of 25–35 pounds of weight gain during pregnancy for individuals with a normal pre-pregnancy body mass index. This stable yet suboptimal awareness level calls for renewed efforts in disseminating scientifically grounded, nuanced information on weight monitoring and management in maternal care.
Alcohol consumption during and preceding pregnancy emerges as a critical knowledge domain with a dichotomy of understanding. Reassuringly, 90% of women of childbearing age now refute the myth that moderate consumption of wine or beer during pregnancy is safe, an 8-point improvement from 82% in 2025. Nonetheless, approximately one-third of all adults lack clarity on the recommendation to abstain from alcohol entirely when trying to conceive, underscoring a public health communication challenge. Epidemiological evidence unequivocally substantiates that no safe threshold of prenatal alcohol exposure exists, given its teratogenic potential culminating in fetal alcohol spectrum disorders (FASD), a circumstance the current survey reveals is not comprehensively internalized.
Parallel to alcohol-related insights, perceptions about tobacco use during pregnancy exhibit high, but imperfect, levels of awareness. A majority recognize smoking’s role in elevating the risk of congenital abnormalities, preterm labor, low birth weight, and sudden infant death syndrome (SIDS). Particularly noteworthy is the statistically significant greater awareness among women aged 18 to 49 about the association between secondhand smoke exposure and SIDS risk. These findings validate the efficacy of decades-long anti-smoking campaigns while pointing towards focusing efforts on complete cessation and avoidance of smoke exposure in perinatal contexts.
Another domain of significant public health interest covered by the survey is breastfeeding awareness, which has substantial implications for infant immunity and long-term health development. Approximately three-quarters of respondents understand the dual benefits breastfeeding confers on both infants and nursing mothers. This knowledge aligns with biological research elucidating how maternal antibodies and essential nutrients through breast milk modulate neonatal immune responses and metabolic programming. Promoting this awareness remains pivotal, as breastfeeding rates still vary widely across demographic groups and regions.
The survey also illuminates the public’s grasp of safe infant sleep practices—a crucial factor in mitigating sudden and unexpected infant deaths. The data reveal that 77% of women of childbearing age appropriately recognize that placing infants on their backs during sleep is the recommended practice, an evidence-based intervention endorsed by the American Academy of Pediatrics and the CDC. This knowledge level, significantly higher than in broader adult groups, suggests effective targeting in maternal education but simultaneously highlights that almost a quarter of women remain unaware, necessitating ongoing outreach.
Collectively, these nuanced insights from the APPC survey provide an essential snapshot of the current state of maternal health knowledge in the United States. The findings emphasize that while foundational concepts have permeated public consciousness, detailed, actionable understanding lags in critical areas such as prenatal nutrition, alcohol cessation timing, iron supplementation protocols, and gestational weight gain guidelines. Addressing these gaps through multi-disciplinary frameworks involving clinicians, public health officials, and social networks is paramount to improving maternal and infant health outcomes.
Moreover, the methodological robustness of the survey—employing a probability-based, nationally representative panel with a margin of error of ±3.5 percentage points—confers high confidence in its findings. Conducted by SSRS, an independent research company, under the Annenberg Health and Risk Communication Institute, the survey integrates rigorous scientific methodology with broad societal perspectives. Its longitudinal design, initiated in 2021, allows for tracking temporal trends in knowledge and behavior, informing evidence-based policy and communication strategies.
In light of rising trends in alcohol consumption during pregnancy observed over the last decade, as corroborated by external analyses such as STAT News, these knowledge deficits take on added urgency. More than one in eight pregnant adults report recent alcohol use—a pattern that contravenes medical consensus and increases the risk for adverse neurodevelopmental outcomes in offspring. Understanding and reinforcing the imperative to avoid alcohol well before conception is vital to reversing this trend and mitigating its public health impacts.
Ultimately, this comprehensive survey accentuates the interplay between scientific understanding, public knowledge, and health behaviors in the realm of maternal and infant health. Bridging informational divides through culturally sensitive, accessible, and evidence-based education stands as a fundamental challenge and opportunity for healthcare systems and public health institutions committed to optimizing life course outcomes.
