Table 2 Multivariable logistic regression models showing odds of misperceiving physical activity, adjusted for age and sex, within the inactive and active groups

From: Awareness of physical activity in healthy middle-aged adults: a cross-sectional study of associations with sociodemographic, biological, behavioural, and psychological factors

  Inactive (n = 258) Active (n = 195)
  Overestimators (n = 130) vs. Realistic inactives (n = 128)* Underestimators (n = 71) vs. Realistic actives (n = 124)*
  Odds ratio 95% CI p-value Odds ratio 95% CI p-value
