Background:Physical activity(PA)is important for cancer survivors.Trials of remotely delivered interventions are needed to assist in reaching under-served non-metropolitan cancer survivors.The objective of this study was to ascertain whether wearable technology,coupled with health coaching was effective in increasing PA in breast and colorectal cancer survivors living in regional and remote areas in Australia.Methods:Cancer survivors from 5 states were randomized to intervention and control arms.Intervention participants were given a Fitbit Charge 2TMand received up to 6 telephone health coaching sessions.Control participants received PA print materials.Accelerometer assessments at baseline and 12 weeks measured moderate-to-vigorous PA(MVPA),light PA,and sedentary behavior.Results:Eighty-seven participants were recruited(age=63±11 years;74(85%)female).There was a significant net improvement in MVPA of 49.8 min/week,favoring the intervention group(95%confidence interval(95%CI):13.6-86.1,p=0.007).There was also a net increase in MVPA bouts of 39.5 min/week(95%CI:11.9-67.1,p=0.005),favoring the intervention group.Both groups improved light PA and sedentary behavior,but there were no between-group differences.Conclusion:This’s the first study to demonstrate that,when compared to standard practice(i.e.,PA education),a wearable technology intervention coupled with distance-based health coaching,improves MVPA in non-metropolitan cancer survivors.The results display promise for the use of scalable interventions using smart wearable technology in conjunction with phone-based health coaching to foster increased PA in geographically disadvantaged cancer survivors.

A critical appraisal is made of the evidence that depression is a causal risk factor for coronary heart disease. PubMed and Science Citation Index were searched for relevant papers. Forty eight papers satisfying inclusion criteria and reporting an association between a measure of depression and a coronary disease outcome were compared in terms of baseline assessment, exposure and endpoint definition, covariates measured and whether changes in, or treatment of, depression was assessed during follow-up. There was considerable variation in the definition of depression and coronary heart disease and contradictory findings are reported. Conventional risk factors for coronary heart disease were not assessed consistently or adequately. Only three of the forty-eight papers gave consideration to the time course of depression during follow-up and prior to study entry. Potentially confounding variables such as anxiety, personality traits and other psychiatric disorders were not taken into consideration in the majority of papers. Treatment of depression during the follow-up period was not mentioned in any of the papers. In light of identified methodological shortcomings and the inconsistent findings reported we suggest that there is as yet no convincing evidence that depression is an independent causal risk factor for coronary heart disease.
