Participants without arthritis in 2011 were selected as the study population, with VPD designated as the primary exposure factor and newly diagnosed arthritis cases as the outcome variable. Logistic regression models were used to estimate the association between VPD and incident arthritis. Restricted cubic spline (RCS) analyses were conducted to assess potential nonlinearity. Subgroup analyses were performed to examine effect heterogeneity across population subgroups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sec003\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A total of 4615 subjects were included, and a total of 1317 subjects were reported to be diagnosed with arthritis during approximately 10 years of follow-up (2011\u20132020). The VPD level in the arthritis group was lower than that in the non-arthritis group (5.184\u2009\u00b1\u20090.828 vs 5.291\u2009\u00b1\u20090.818, p\u2009&lt;\u20090.001). All logistic regression models showed that VPD was linearly related to the incidence of arthritis, and the relationship remained consistent even when VPD was categorized. RCS analysis showed that the incidence of arthritis decreased significantly with increasing VPD (p\u2009&lt;\u20090.05), especially when VPD was lower than 5.28. Subgroup analysis indicated that VPD exerted a stronger protective effect against arthritis among rural residents (p for interaction\u2009=\u20090.006).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sec004\">\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>VPD was found to be negatively associated with the incidence of arthritis among middle-aged and elderly populations, with a particularly stronger effect observed in rural residents.
