This cohort study aimed to identify the accumulation patterns of objectively measured ambulatory activity (AA) variables in middle-aged and older Japanese women examine relationship these derivative with onset metabolic syndrome (MetS). A total 794 (mean age: 56.2 years) provided assessed AA data using a uniaxial accelerometer. The number steps, time accumulated light-intensity (LIAA) moderate-to-vigorous intensity (MVAA) ratio MVAA (LIAA + MVAA) were calculated. Latent profile analysis was used participant groups based on their distinct patterns. Logistic regression models assess association MetS after adjusting for age, sex, education, alcohol habit, smoking energy intake, components present at baseline. Four identified: Group had low levels variable; group B certain or more steps primarily through MVAA; C LIAA; D high level variables. Over course 5-year follow-up period, 61 participants (7.7%) developed MetS. multivariate-adjusted odds (95% confidence interval) B, C, relative 0.416 (0.166-1.218), 0.451 (0.223-0.914), 0.933 (0.365-2.382), respectively. significantly lower than A. accumulating regardless AA, may help reduce risk compared inactive
