Background Studies have shown that decreased gait speed is associated with impaired cognitive function. However, whether this association equivalent across ages or genders in the older population remains unclear. Thus, we examined between mild impairment (MCI) and emphasising influence of age gender. Methods Overall, 8233 Japanese participants aged ≥65 years were enrolled cross‐sectional study 2016 2018. After stratification by gender group, participants' speeds divided into quintiles, difference MCI prevalence at each quintile was calculated. Logistic regression analyses performed to assess odds for Results Males had a consistently higher than females. The increased as decreased. revealed multivariable‐adjusted model 2, ratios (95% confidence interval; CI) 2.02 (1.47–2.76) females 1.75 (1.29–2.38) males slowest quintiles compared fastest quintile. In stratified analyses, only showed an age‐dependent increase associations MCI, while exhibited comparable groups. Conclusions Reduced may vary according age. Therefore, could serve valuable screening tool gender‐ clinical implications.
