Association of Musculoskeletal Pain With Sedentary Behavior in Public School Teachers: The Role of Habitual Physical Activity.

Background: Sedentary behavior has been associated with musculoskeletal pain in school teachers. However, our hypothesis is that physical activity practice could mitigate this association.

Aim: The aim of this study was to investigate the relationship of musculoskeletal pain with high screen-based sedentary behavior among public school teachers and whether physical activity could mitigate this relationship.

Immobilization of papain enzyme on a hybrid support containing zinc oxide nanoparticles and chitosan for clinical applications.

A new hybrid bionanomaterial composed of zinc oxide nanoparticles (ZnO NPs) and chitosan was constructed after enzymatic immobilization of papain for biomedical applications. In this work, we report the preparation and characterization steps of this bionanomaterial and its biocompatibility in vitro. The properties of the immobilized papain system were investigated by transmission electron microscopy, zeta potential, DLS, UV-vis absorption spectroscopy, FTIR spectroscopy, and X-ray diffraction.

Association of musculoskeletal pain with poor sleep quality in public school teachers.

Background: Teachers perform repetitive movements all day, which can cause pain in body regions. This article analyzes the association of pain with sleep quality in this population.

Objective: The objective of the study was to analyze the relationship of musculoskeletal pain and sleep quality in teachers from public schools.

Association between sedentary behavior, obesity and hypertension in public school teachers.

The present study aimed to verify the prevalence and association of sedentary behavior and its breaks with obesity and cardiovascular risk factors in teaching professionals. The sample was composed by 245 public school teachers (186 women and 59 men), with a mean age of 45 yr. Sedentary behavior was evaluated by self-reported screen time in different devices (television, computer, cellphone/tablet), and sedentary breaks at work and leisure were assessed by a Likert scale (never, rarely, sometimes, often, always).

Association of sedentary behaviour patterns with dietary and lifestyle habits among public school teachers: a cross-sectional study.

Objectives: To analyse the association of sedentary behaviour patterns with dietary and lifestyle habits among public school teachers.

Design: Cross-sectional study.

Participants: A sample of 245 teachers (186 women and 59 men) with mean age of 45.
