30-Second Takeaway
- Roughly four in ten cancers worldwide are attributable to modifiable exposures, dominated by smoking, infections, and alcohol.
- Most U.S. adults with prediabetes would benefit most from intensive lifestyle interventions when individualized diabetes risk is modeled.
- Structural, low-agency policies—income support, housing, regulation—most consistently narrow health inequities across high-income countries.
- Climate- and pollution-related health burdens are measurable now, strengthening the case for heat, air quality, and extreme weather planning.
- High-quality patient–provider communication reliably boosts high-value care use but does not reliably suppress all low-value services.

Targeting structural risks, climate threats, and communication gaps to sharpen prevention impact
Over one-third of global cancer incidence is attributable to 30 modifiable risk factors
This GLOBOCAN-based analysis estimated that 37.8% of 2022 global cancer cases were attributable to 30 modifiable exposures. The preventable fraction ranged widely by sex and region, from about one-quarter to over one-half of cancers in men. Smoking was the leading contributor, followed by infections and alcohol, with lung, stomach, and cervical cancers comprising nearly half of preventable cases. Findings support prioritizing tobacco control, infection prevention, and alcohol policies as central components of national cancer control plans.
Modeled intensive lifestyle intervention substantially lowers short-term diabetes risk in U.S. adults with prediabetes
Using NHANES 2015-2020 data, investigators modeled 3-year diabetes risk under standard care, metformin, and intensive lifestyle for 2,778 adults with prediabetes. Predicted diabetes risk averaged 18.4% with standard recommendations, 14.4% with metformin, and 8.0% with intensive lifestyle intervention. An individualized strategy selecting the lowest-risk option per person yielded a mean predicted risk of 7.6%. Intensive lifestyle was the optimal modeled strategy for 91% of participants, underscoring its potential population impact if implemented at scale.
Recent NHANES data quantify the burden of uncontrolled blood pressure among U.S. adults with hypertension
This study used 2021-2023 NHANES data to estimate the proportion of U.S. adults with hypertension whose blood pressure remains above goal. Analyses provide up-to-date national surveillance on control gaps after recent guideline and treatment changes. The findings can inform benchmarking, quality improvement, and targeting of intensified hypertension management in ambulatory and population health settings.
