Distributional data analysis of accelerometer data from the NHANES database using nonparametric survey regression models

  title={Distributional data analysis of accelerometer data from the NHANES database using nonparametric survey regression models},
  author={Marcos Matabuena and Alexander Petersen},
Accelerometers enable an objective measurement of physical activity levels among groups of individuals in free-living environments, providing high-resolution detail about physical activity changes at different time scales. Current approaches used in the literature for analyzing such data typically employ summary measures such as total inactivity time or compositional metrics. However, at the conceptual level, these methods have the potential disadvantage of discarding important information from… 


Organizing and Analyzing the Activity Data in NHANES
This work provides the tools to transition from “available data online” to “easily accessible and usable data”, which substantially reduces the large upfront costs of initiating studies of association between physical activity and human health outcomes using NHANES.
Glucodensities: A new representation of glucose profiles using distributional data analysis
The glucodensity possesses an extraordinary clinical sensitivity to capture the typical biomarkers used in the standard clinical practice in diabetes and is a natural generalization of the time in range metric, this being the gold standard in the handling of CGM data.
Kernel k-Groups via Hartigan’s Method
This paper considers a formulation for the clustering problem using a weighted version of energy statistics in spaces of negative type using kernel k-groups, which is an extension of Hartigan’s method to kernel spaces and shows improved performance in higher dimensions.
Accelerometer-measured physical activity and sedentary time in a cohort of US adults followed for up to 13 years: the influence of removing early follow-up on associations with mortality
The pattern of associations suggested total physical activity and moderate-to-vigorous physical activity were associated with lower mortality after more than 10  years of follow-up and excluding the first 5 years of observation time to minimize the impact of reverse causation bias.
Big Data for Finite Population Inference: Applying Quasi-Random Approaches to Naturalistic Driving Data Using Bayesian Additive Regression Trees
This work proposes using an alternative pseudo-weighting approach that allows the use of flexible non-parametric models to fit more flexible modern predictive tools such as Bayesian Additive Regression Trees (BART), which automatically detect non-linear associations as well as high-order interactions.
Current Evidence of Measurement Properties of Physical Activity Questionnaires for Older Adults: An Updated Systematic Review
Until more high-quality evidence is available, the PASE for measuring total PA and the PASB-Q for measuring MVPA in older adults are recommended, however, they are not equally qualified among different languages.
Effect of exercise training for five years on all cause mortality in older adults—the Generation 100 study: randomised controlled trial
This study suggests that combined MICT and HIIT has no effect on all cause mortality compared with recommended physical activity levels, however, it is observed that a lower allCause mortality trend after HIIT is observed compared with controls and MICT.
Generalizing randomized trial findings to a target population using complex survey population data.
This work proposes and investigates ways to incorporate survey weights when generalizing trial findings to a population represented by a complex survey sample, and examines the performance of the proposed estimator through simulations in comparison to estimators that ignore the complex survey design.

In a study of 96,476 participants from the UK Biobank cohort who had their physical activity objectively measured by accelerometer, both the volume of physical activity and its intensity were
