Associations of previous weight, previous step count and recent change in step count with subsequent weight (adjusted model)
| Parameter | Estimate | SE | χ2 | p Value | Joint effects |
|---|---|---|---|---|---|
| Log (weight (t−3)) | 0.0885 | 0.0123 | 46.8 | <0.0001 | 747.3 |
| Log (weight (t−2)) | 0.1339 | 0.0183 | 43.0 | <0.0001 | (p<0.0001) |
| Log (weight (t−1)) | 0.7638 | 0.0191 | 484.9 | <0.0001 | |
| Step count (t−2) | −0.0003 | 0.0003 | 0.9 | 0.34 | 5.9 |
| Change in step count (t−1) | −0.0008 | 0.0003 | 5.9 | 0.02 | (p=0.05) |
Adjusted for weight values from last three annual visits (t−1, t−2, t−3) and baseline covariates (age, sex, race, region, smoking status, waist circumference, systolic blood pressure, pulse pressure, chronic obstructive pulmonary disease, atrial fibrillation/flutter, low-density lipoprotein and high-density lipoprotein cholesterol, platelets, haemoglobin, log of albumin/creatinine ratio, sodium, estimated glomerular filtration rate, ECG abnormalities, congestive heart failure, cerebrovascular disease, coronary heart disease, pulmonary disease, peripheral artery disease and family history of diabetes).
Weight expressed per kg and step count per 2000 steps.
