About this trial
The pilot study will adopt a 2-arm, pretest-posttest, and assessor-blind randomized controlled trial design to examine the feasibility and acceptability of a theory-based health behaviour change intervention and examine its effects on waist circumference (primary outcome), kidney function (estimated glomerular filtration rate, urine albumin-to-creatinine ratio, primary outcome), dietary behaviour, physical activity, exercise capacity and self-efficacy of diet behaviour and physical activity among Chinese adults with metabolic syndrome and chronic kidney disease.
Researchers will compare the theory-based health behaviour change intervention to usual care to see if the theory-based health behaviour change intervention can reduce waist circumference and preserve kidney function over three months.
A total of 40 adults with metabolic syndrome and chronic kidney disease will be recruited, with 20 participants in each group. Data will be collected at two-time points (baseline and immediate post-intervention) via an online questionnaire survey platform (Qualtrics) by researchers blinded to the group allocation to reduce the detection bias.
