From the literature we've seen research mostly examines pregnancy in adults (>20 years), but our population is 14-18 years old. We'd love any feedback on if we should go with cutpoints for teens/children or for pregnant women. Thanks!
Hi Bethany Forseth, an interesting question. I would suggest adolescent specific cut-points would be sensible, it is at least justifiable. As for the pregnant women cut-points, I am not personally familiar with the existence of such thresholds? If they do exist, a sensible approach would be to compare the 2 cut-points.
However, ideally you could calibrate the accelerometer outputs to create your own, validated cut-points, specific to your population.
A further option, depending on the brand and accessibility of the accelerometer, you could analyse the signal output using GGIR. Of course, this depends on your research question.
Happy to chat further if needed,
