Adjusted linear regression models showing the associations between continuous measures of total accumulated moderate-to-vigorous-intensity physical activity (MVPA) time and body mass index (BMI) with glycated haemoglobin (HbA1c)
| Adjusted linear regression model | HbA1c (dual units) | MVPA (30 min/day) | BMI (1 kg/m2) | ||
|---|---|---|---|---|---|
| Beta (99% CI)* | p Value | Beta (99% CI)† | p Value | ||
| Model 1 | (mmol/mol) (%) | −0.9 (−1.4 to −0.4) −0.08 (−0.13 to −0.04) | <0.001 | 0.2 (0.1 to 0.3) 0.02 (0.01 to 0.03) | <0.001 |
| Model 2 | (mmol/mol) (%) | −0.7 (−1.2 to −0.2) −0.07 (−0.11 to −0.02) | <0.001 | 0.2 (0.1 to 0.3) 0.02 (0.01 to 0.03) | <0.001 |
All analyses controlled for primary sampling units, clustering and survey weights. Bold indicates statistical significance at p<0.01. Model 1 adjusted for: age, ethnicity, income, sex, any prescribed medication and accelerometer wear-time. Model 2 additionally adjusted for BMI (for MVPA analysis) and MVPA (for BMI analysis).
*Beta coefficients represent the average difference in HbA1c (mmol/mol) (%) for each 30 min/day increment in MVPA.
†Beta coefficients represent the average difference in HbA1c (mmol/mol) (%) for each 1 kg/m2 increment in BMI.
