<strong>Exericse as preventative medicine!</strong></p>
<p>
A recent cohort study of over 2,000 adults (mean age approx. 45) over approximately 11 years of follow-up investigated the association of step count with mortality.</p>
<p>
This study found that those participants taking at least 7,000 steps per day compared to those taking fewer steps had a 50%-70% lower risk of mortality. They did not find an association with step intensity.</p>
<p>
</p>
<p>
Another recent study investigated the dose-response association between daily step count and intensity and the incidence of all-cause dementia.</p>
<p>
</p>
<p>
Uk based study of >78,000 adults aged 40 to 79 years with approximately 7 years of follow-up. Data from wrist accelerometer and registry-based dementia diagnoses.</p>
<p>
</p>
<p>
Optimal step dose was 9826 steps. Minimal dose was 3826 steps (value at which the risk reduction was 50% of the observed max).</p>
<p>
In this study, steps performed at higher intensity (112 steps/min) resulted in stronger associations.</p>
<p>
</p>
<p>
<strong>Conclusions</strong>: A great exercise goal for middle aged and older adults is just under 10,000 steps per day to decrease risks of both overall mortality and dementia.</p>
