Chronic Disease–Related Social and Behavioral Risk Factors and Conditions Among Non-Hispanic American Indian and Alaska Native People: Behavioral Risk Factor Surveillance System, 2011–2023
Dear barry popkin — this week’s five most relevant discoveries, curated for your work in Public Health.
Key findings
Medicine · Public Health
No. 1
This study analyzed Behavioral Risk Factor Surveillance System data from 2011–2023 to characterize chronic disease risk factors among non-Hispanic American Indian and Alaska Native adults. The findings quantify elevated prevalence of smoking, obesity, physical inactivity, and diabetes-related conditions in this population, revealing persistent disparities. For a nutrition epidemiology scholar, these surveillance data pinpoint where dietary interventions and policy changes could most effectively reduce the chronic disease burden in Indigenous communities.

Dental amalgam, chronic disease risk, and removing mercury from dental practice
This review revisits the neurologic risks of mercury from dental amalgam in light of the Minamata Convention’s phase-down targets. It argues that mercury-containing dental fillings remain a significant contributor to global mercury emissions and human exposure, particularly through food chain contamination. For a public health nutritionist, the implications for dietary mercury intake from fish demand renewed attention to food safety monitoring and nutritional guidance for populations reliant on seafood.

[Review] Implementation of risk prediction and stratification approaches for ageing populations in Australian healthcare: a systematic review
This systematic review examined how risk stratification tools for adults aged 40+ have been implemented in Australian healthcare, following PRISMA and SWiM guidelines. The review identified a gap between tool development and real-world application, with few studies reporting health, functional, or implementation outcomes. For an economist and public health nutritionist, these findings highlight the underutilization of prognostic tools that could target nutrition-related chronic disease interventions to the highest-risk older adults.

The Effect of Prematurity on the Occurrence of Caries at Four Years of Age: A Prospective Cohort Study
This prospective cohort from a Brazilian birth cohort found that children born before 34 weeks had 40% lower caries incidence at age four compared with term infants, and those born at 37–38 weeks had 20% lower incidence. Mediation analysis revealed that the number of teeth at 12 months explained the inverse association, linking lower gestational age to fewer erupted teeth and thus less caries. For a nutrition epidemiologist, the study’s inclusion of sugar consumption as a mediator underscores the role of early dietary exposures in caries development and highlights the importance of nutritional guidance from infancy.

Ultralow-Volume Treatments for Mosquito-Borne Diseases
This Viewpoint discusses the use of organophosphate and pyrethroid ultralow-volume spraying for mosquito management to prevent mosquito-borne disease outbreaks. It highlights the continued reliance on chemical vector control despite growing concerns about resistance and ecological side effects. For a public health nutritionist, this piece connects environmental health policy to nutritional outcomes — vector-borne illnesses impair food security and work productivity, especially in vulnerable populations where nutritional status may influence disease severity.
