* Study quality assessment criteria were from the Newcastle-Ottawa Quality Assessment Scale for cohort studies.23 According to this scale, a study can be awarded a
maximum of one star for each item within the Selection and Outcome categories, and a maximum of two stars for Comparability. The overall score is determined by the total
number of stars. The overall score was then categorised into three levels: Low (0-3), Medium (4-6), and High (7-9).
a   Representativeness: a star was given if the cohort was truly or somewhat representative of exposed individuals in the community.
b   Selection: all studies were awarded a star due to the nature of the study design.
c   Ascertainment exposure: a star was given if the step count was ascertained by secure record (e.g. accelerometer).
dOutcome: a star was given in the case of all-cause mortality, if the study excluded individuals with major chronic disease. In relation to the other health outcomes, a star was
given if the study excluded those with the same outcome of interest (e.g. for the cardiovascular disease outcome, they excluded those with existing cardiovascular disease).
For outcomes measured using continuous variables (typically physical function and cognitive decline), the item was rated NA.
eComparability: up to two stars could be given – one if the study adjusted for age and health, whether by way of statistical adjustment for confounders or exclusion of
participants; another star if they adjusted for other factors (even if they did not adjust for age and health).
fAssessment of outcome: a star was given if the health outcome was assessed by independent or blind assessment or confirmation of the outcome by reference to secure
records, or by record linkage.
g   Follow-up: a star was given if there was at least 2 years’ follow-up.
                                                                                                                                                                                  80
h   Adequacy of follow-up: a star was given if there was no loss to follow-up or any loss was unlikely to introduce bias.
