Letter to the Editor: Standardized use of the terms “sedentary” and “sedentary behaviours”

The quality of life in the workplace can be achieved by creating a place more humanized and strategies that provide wellness to workers. The aim of this study was to investigate the effectiveness of telehealth education program to promote quality of life of office workers.

This is a cluster randomized controlled trial (RCT). The participants were office workers computer users (n = 326). All received 9 audiovisual content (grouped into topics: musculoskeletal health, healthy diet, and mental health) that addresses the real needs identified by them in the focus groups. The intervention group (n = 178) was instructed to seek the tutor support about topics addressed by the audiovisual content. The primary outcome measure was quality of life by WHOQOL-BREF. The secondary outcome measure was level of physical activity of the participants. Data analysis was performed by General Linear Mixed Model. After six months of telehealth education program a general improvement in health and environmental domain, was observed in the intervention group. During that period, a within-group analysis showed that there was a significant improvement in the intervention group, with respect to quality of life in general health (p < 0.05) and in the environmental domain (p < 0.01).

In the baseline to the eighth month, there were statistically significant changes within-group for the general health (p < 0.05) and for the physical domain (p < 0.01) in both groups (p < 0.01). Telehealth education program promoted an improvement in the participants' quality of life. There was no benefit in favor of the telehealth education program, with tutor support in relation to the conventional program.

The trial was prospectively registered at ClinicalTrial.gov (NCT02980237). The date of registration was August 23, 2016.

e-Learning, a means by which to expand people’s access to information can be effective in promoting health in the workplace. This study to present steps in the development of an e-health education program at the workplace.

This study aimed to present all steps of develop a telehealth education program for computer users using formative research to identify themes to health education for workers.

A team of expert conducted focus groups with administrative workers (n = 36 participants) to identify thematic health to the development of program. Three meetings were audio video recorded, and notes. All data were based on constant analysis, classical content analysis and keywords in-context.

The content of the nine audio videos included four musculoskeletal health topics (Walking Program, Back School, Muscle Relaxation Techniques, and Work-related Musculoskeletal Diseases); three to healthy diet (Eating and Commensality, Ultra-processed Food and Food labeling, and Oil and Fat); two to mental health (Burnout Syndrome and the Meaning of work).

The proposed steps in the development of a workplace e-health education program were successfully achieved. The engagement of the workers’ staged focus groups was fundamental to the choice of themes relevant to the population in question.

Sedentary behavior has been found to be associated with negative health outcomes independently of physical activity in older adults. This systematic review collates interventions to reduce sedentary behavior in non-working older adults, assessing whether they are effective, feasible, and safe. A systematic search identified 2560 studies across five databases. Studies were included where participants were ≥60 years on average with none younger than 45, and participants did not work >2 days per week. A total of six studies were identified, three of which included control groups, while the other three were repeated-measures pre-post designs. Only one study randomised participants. The overall level of quality of included studies was poor. A narrative synthesis was conducted, as the level of heterogeneity in outcomes and outcome reporting were too high for a meta-analysis to be performed. The narrative synthesis suggested that interventions have the potential to reduce sitting time in non-working older adults. Included studies reported feasible and safe implementations of their interventions in most samples, except for one subsample from a study of people in sheltered housing. Objectively measured reductions in sitting time were between 3.2% and 5.3% of waking time, or up to 53.9 min per day. Future studies should employ more rigorous designs to assess the effects of reducing sedentary behavior on health and physical function, and should include follow-ups to measure the duration of behavior change.

Sedentary behaviour and lack of physical activity threatens health. Research concerning these behaviours of inpatients with severe mental illness is limited but urgently needed to reveal prevalence and magnitude. In total, 184 inpatients (men n =108, women n =76, mean age 57,4, 20% first generation antipsychotics, 40% second generation antipsychotics, 43% antidepressants, mean years hospitalisation 13 years), with severe mental illness of a Dutch psychiatric hospital wore an accelerometer for five days to objectively measure total activity counts per hour and percentages in sedentary behaviour, light intensity physical activity and moderate to vigorous physical activity. Accelerometer data were compared with data of 54 healthy ward employees. Patients showed significantly less activity counts per hour compared to employees (p=0.02), although the differences were small (d=0.32). Patients were sedentary during 84% of the wear time (50 min/h), spend 10% in light intensity physical activity and 6% in moderate to vigorous physical activity. Age was the only significant predictor, predicting less total activity counts/h in higher ages. Decreasing sedentary behaviour and improving physical activity in this population should be a high priority in clinical practice.

The school classroom environment often dictates that pupils sit for prolonged periods which may be detrimental for children's health. Replacing traditional school desks with standing desks may reduce sitting time and provide other benefits. The aim of this systematic review was to assess the impact of standing desks within the school classroom.

Studies published in English up to and including June 2015 were located from online databases and manual searches. Studies implementing standing desks within the school classroom, including children and/or adolescents (aged 5–18 years) which assessed the impact of the intervention using a comparison group or pre–post design were included.

Eleven studies were eligible for inclusion; all were set in primary/elementary schools, and most were conducted in the USA (n = 6). Most were non-randomised controlled trials (n = 7), with durations ranging from a single time point to five months. Energy expenditure (measured over 2 h during school day mornings) was the only outcome that consistently demonstrated positive results (three out of three studies). Evidence for the impact of standing desks on sitting, standing, and step counts was mixed. Evidence suggested that implementing standing desks in the classroom environment appears to be feasible, and not detrimental to learning.

Interventions utilising standing desks in classrooms demonstrate positive effects in some key outcomes but the evidence lacks sufficient quality and depth to make strong conclusions. Future studies using randomised control trial designs with larger samples, longer durations, with sitting, standing time and academic achievement as primary outcomes, are warranted.

Time spent watching TV by Europeans has been calculated to be 22.1 h per week on average and it has shown to be correlated with a series of physical and mental problems in adults. Very little research is available in population over 65. This study aimed at evaluating the association between TV viewing and mental disorders and cognitive performance, taking into account the general physical activity level and socio-demographic characteristics in Europe.

Within the MentDis_ICF65+ study, a subsample of 1383 subjects aged 65–84 years were assessed by the Composite International Diagnostic Interview (CIDI65+) and the International Physical Activity Questionnaire (IPAQ) for physical activity evaluation. Time spent in watching TV was assessed through a self report instrument.

Forty-three per cent of the total sample watched TV for 5–7 days a week for 2 or more hours every day. Females, people who lived alone, older subjects and those with lower education significantly watched TV for a longer time. Stepwise multiple regression showed statistically significant inverse correlation between Mini-Mental State Examination scores and TV viewing time (p < 0.001). Apart from a negative association with Major Depressive Disorder, no particular associations were found between TV viewing and psychopathological diagnoses.

Given the relationship of time spending watching TV with cognitive impairment, awareness should be raised about the possible negative effects of TV viewing on the elderly and programs to reduce TV viewing time should be set up.
