To examine the association between navigational health literacy (HL), defined as the skills required to effectively navigate healthcare systems, access services and make informed decisions and healthcare utilisation among French adults with and without chronic health conditions.

Cross-sectional online survey.

National survey conducted in metropolitan France as part of the Health Literacy Survey (HLS₁₉) in 2020 and 2021.

A total of 2 003 individuals were included: 1103 without chronic condition and 900 with at least one chronic condition.

Number of general practitioner (GP) and specialist visits in the previous 12 months

The chronic condition group reported more frequent GP (4.3 vs 2.1/year) and specialist (2.8 vs 1.1/year) visits than the no chronic condition group. A high navigational HL was significantly associated with fewer GP (p=0.016) and specialist visits (p

High navigational HL was associated with less healthcare utilisation in individuals with no chronic condition. Among the chronic condition group, this aspect seemed less influential, likely due to greater healthcare system familiarity and structured care. Our findings highlight the importance of strengthening HL navigation skills early to improve healthcare use.
