HIGHER diet-induced gut microbiota scores in NHANES 2011–2018 were associated with lower gynecologic cancer odds in all U.S. females.
Diet Induced Gut Microbiota Score and Cancer Risk
Researchers evaluated whether the diet induced gut microbiota (DI-GM) score, a dietary index designed to reflect food choices that support microbial health, was associated with gynecologic cancer (GC) risk in U.S. women. Using The U.S. National Health and Nutrition Examination Survey (NHANES) 2011–2018, the analysis included 8,512 adult women aged 20 years and older.
The DI-GM score was derived from intake of 14 food groups categorized as beneficial or harmful to gut microbial health. Higher scores indicated stronger adherence to a microbiota-friendly diet pattern, reflecting greater intake of foods expected to support microbial diversity and short-chain fatty acid production.
Higher Scores Linked to Lower Gynecologic Cancer Odds
Women with gynecologic cancer had significantly lower DI-GM scores than those without the condition (mean 4.7 versus 5.0). In multivariable, survey-weighted logistic regression models adjusted for covariates, each one-unit increase in DI-GM score was associated with lower odds of gynecologic cancer (adjusted OR: 0.92; 95% CI: 0.87–0.98).
When comparing broader score groups, participants with DI-GM scores of 6 or higher had 27% lower odds of gynecologic cancer versus those scoring 0–3. The beneficial component of the DI-GM score was also independently associated with lower GC risk, suggesting that foods supporting microbial health may be driving the observed relationship. Stratified analyses did not show significant effect modification, indicating the association was broadly consistent across subgroups evaluated.
Clinical Takeaway for Women’s Health
These findings support the concept that microbiota-friendly dietary patterns may be linked to reduced gynecologic cancer risk at a population level. While the study design does not establish causality, it strengthens the rationale for considering dietary quality through a gut microbiota lens when discussing long-term risk reduction strategies with patients, alongside established screening and prevention approaches.
