Fat‐Free Mass Predictions From Anthropometrics in South African Prepubertal Children

Journal of Paediatrics and Child Health, EarlyView.
ABSTRACT Background South African children face a double burden of malnutrition from undernutrition and rising obesity. Simple, accurate methods to estimate fat‐free mass, a key health indicator, are needed, as bioelectrical impedance analysis is limited by cost, availability and lack of local validation.

Metrology of two wearable sleep trackers against polysomnography in patients with sleep complaints

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Sleep trackers are used widely by patients with sleep complaints, however their metrological validation is often poor and relies on healthy subjects. We assessed the metrological validity of two commercially available sleep trackers (Withings Activité/Fitbit Alta HR) through a prospective observational monocentric study, in adult patients ...

Feasibility and usability of three consecutive nights with self‐applied, home polysomnography

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary In‐laboratory polysomnography, the gold‐standard for diagnosing sleep disorders, is resource‐demanding and not conducive to multiple night evaluations. Ambulatory polysomnography, especially when self‐applied, could be a viable alternative. This study aimed to assess the feasibility and reliability of self‐applied polysomnography over three ...

Differential Nap‐To‐Nap Stability of Sleep Spindles, Slow Waves, and their Temporal Coupling: An Exploratory Study

Journal of Sleep Research, EarlyView.
ABSTRACT Slow waves and sleep spindles characterise non‐rapid eye movement (NREM) sleep and support cognitive and plasticity‐related functions. While their stability across nights is well established, less is known about their consistency across daytime naps.
