Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The Fitness for the Ageing Brain Study (FABS) RCT was conducted between 2004-2006 in older adults with subjective cognitive decline (SCD), with or without mild cognitive impairment (MCI) with assessments at 0, 6, 12 and 18 months. The intervention group had a 6-month home-based physical activity (PA) intervention.
In Stage 1 of the long-term follow-up we will evaluate the long-term effects of that PA program on PA, cognition, function and health for this cohort after 10-15 years with a repeat of the assessments from the original trial. There is no active intervention in this period.
In Stage 2 we proposed to access information from the WA Health Department data linkage service for those not withdrawing from the original study and those opting out of the follow-up interview.
Both the Intervention and control group will be invited to participate in the follow-up Study.

Statistical methods / analysis
For the original trial the participation of 84 volunteers in each of the two groups (total=168) at baseline resulted in power of 90% with alpha set at 0.05. We estimated a drop out rate of 20%, which led to the recruitment of 170 participants with power set at 80% (85 randomly allocated to each group).
The primary analysis was based on intention-to treat (ITT) using the multiple imputation (MI) procedure of SAS. Each imputed dataset was analysed using a mixed effect model with repeated measures, and parameter estimates were then averaged across datasets. The ITT analysis was then followed by a complete case (CC) analysis, where only participants with valid data at all time points were included in the analysis.

Repeated measures procedure was used in an analysis of covariance (ANCOVA) in both the ITT and CC analyses. For ITT data, a mixed model with repeated measures in SAS was used while for CC data, a GLM for repeated measures ANCOVA in SPSS was used. Covariates such as age, sex, education level, marital status and premorbid IQ were included in the multivariate model. In addition, data from each follow-up time point were subtracted from baseline for each participant to examine the magnitude of change over time. Repeated measures ANCOVA analyses were applied to evaluate change from baseline in the same manner described above.
For the Follow-up study frequency counts and chi square analyses will be used to determine the distribution of subjects for demographic data; and categorical data such as mortality, morbidity, health conditions and health service utilisation. Changes over time and between group differences in cognition, health, PA, everyday function, QoL and health service utilisation and attributed costs will be analysed with longitudinal mixed-effects regression models with maximum restricted likelihood estimation to accommodate missing observations without deletion of cases. Multiple regression models will be used to identify factors associated with cognitive decline and other outcomes.
