  • All analyses controlled for primary sampling units, clustering and survey weights.

  • ‘Physically active’ was defined as: ≥150 min/week of total accumulated MVPA.

  • ‘Physically inactive’ was defined as: <150 min/week of total accumulated MVPA.

  • ‘Obese’ was defined as: BMI≥30.0 kg/m2.

  • ‘Non-obese’ was defined as: BMI<30.0 kg/m2.

  • Bold indicates statistical significance at p<0.01. Model adjusted for: age, ethnicity, income, sex, any prescribed medication and accelerometer wear-time.

  • *Beta coefficients represent the average difference in HbA1c (mmol/mol) (%) in comparison to the ‘physically inactive and obese’ category.
