In a group of healthy Chilean university students aged 18–30, nearly half tested positive for Helicobacter pylori using a stool test, indicating widespread infection even in people without symptoms.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
A systematic review would provide the most accurate estimate of H. pylori prevalence in Chilean young adults by pooling data from multiple representative studies.
A systematic review and meta-analysis of all population-based studies using stool antigen or urea breath test to assess H. pylori prevalence in Chilean individuals aged 18–30, stratified by region, socioeconomic status, and urban/rural setting.
A population-based cohort study would track H. pylori prevalence over time in a representative sample of Chilean youth.
A prospective cohort study recruiting 2000 representative young adults aged 18–30 from diverse regions of Chile, testing H. pylori status via stool antigen at baseline and annually for 5 years, adjusting for socioeconomic and hygiene factors.
A larger cross-sectional survey would validate the 42.7% prevalence in a more representative sample of Chilean youth.
A national cross-sectional survey of 5000 randomly selected Chilean young adults aged 18–30, using stool antigen testing for H. pylori, stratified by region, education level, and household size.
A case-control study could compare H. pylori prevalence between infected and non-infected groups, but is not ideal for estimating overall prevalence.
A case-control study comparing 500 H. pylori-positive and 500 H. pylori-negative young adults in Chile, assessing demographic and behavioral factors, but not designed to estimate population prevalence.
Case reports could document individual infections but cannot estimate population prevalence.
A case series of 100 young adults in Chile diagnosed with H. pylori via stool antigen test, reporting demographic details, but not designed for prevalence estimation.
