“They should stay at their desk until the work’s done”: a qualitative study examining perceptions of sedentary behaviour in a desk-based occupational setting

Background: Workplace sedentary behaviour is a priority target for health promotion. However, little is known about how to effect change. We aimed to explore desk-based office workers’ perceptions of factors that influenced sedentary behaviour at work and to explore the feasibility of using a novel mobile phone application to track their behaviours.

Methods: We invited office employees (n = 12) and managers (n = 2) in a software engineering company to participate in semi-structured interviews to explore perceived barriers and facilitators affecting workplace sedentary behaviour. We assessed participants’ sedentary behaviours using an accelerometer before and after they used a mobile phone application to record their activities at self-selected time intervals daily for 2 weeks. Interviews were analysed using a thematic framework.

Results: Software engineers (5 employees; 2 managers) were interviewed; 13 tested the mobile phone application; 8 returned feedback. Major barriers to reducing workplace sedentary behaviour included the pressure of ‘getting the job done’, the nature of their work requiring sitting at a computer, personal preferences for the use of time at and after work, and a lack of facilities, such as a canteen, to encourage moving from their desks. Facilitators for reduced sedentariness included having a definite reason to leave their desks, social interaction and relief of physical and mental symptoms of prolonged sitting. The findings were similar for participants with different levels of overall physical activity. Valid accelerometer data were tracked for four participants: all reduced their sedentary behaviour. Participants stated that recording data using the phone application added to their day’s work but the extent to which individuals perceived this as a burden varied and was counter-balanced by its perceived value in increasing awareness of sedentary behaviour. Individuals expressed a wish for flexibility in its configuration.

Conclusions: These findings indicate that employers’ and employees’ perceptions of the cultural context and physical environment of their work, as well as personal factors, must be considered in attempting to effect changes that reduce workplace sedentary behaviour. Further research should investigate appropriate individually tailored approaches to this challenge, using a framework of behaviour change theory which takes account of specific work practices, preferences and settings.

How useful is dual energy lateral vertebral assessment in a clinic setting?

Screening for osteoporotic vertebral fractures traditionally involves X-ray of the thoracic and lumbar spine. We evaluated use of dual energy X-ray technology in patients with osteoporosis. We found this technology useful in the clinic setting and it has advantages in that less radiation is delivered to the patient.

Studying Gender in Conference Talks -- data from the 223rd meeting of the American Astronomical Society

We present a study on the gender balance, in speakers and attendees, at the recent major astronomical conference, the American Astronomical Society meeting 223, in Washington, DC. We conducted an informal survey, yielding over 300 responses by volunteers at the meeting. Each response included gender data about a single talk given at the meeting, recording the gender of the speaker and all question-askers. In total, 225 individual AAS talks were sampled. We analyze basic statistical properties of this sample. We find that the gender ratio of the speakers closely matched the gender ratio of the conference attendees. The audience asked an average of 2.8 questions per talk. Talks given by women had a slightly higher number of questions asked (3.2$\pm$0.2) than talks given by men (2.6$\pm$0.1). The most significant result from this study is that while the gender ratio of speakers very closely mirrors that of conference attendees, women are under-represented in the question-asker category. We interpret this to be an age-effect, as senior scientists may be more likely to ask questions, and are more commonly men. A strong dependence on the gender of session chairs is found, whereby women ask disproportionately fewer questions in sessions chaired by men. While our results point to laudable progress in gender-balanced speaker selection, we believe future surveys of this kind would help ensure that collaboration at such meetings is as inclusive as possible.

Paving the way for the use of the SDQ in economic evaluations of school-based population health interventions: an empirical analysis of the external validity of SDQ mapping algorithms to the CHU9D in an educational setting

Purpose
The Strengths and Difficulties Questionnaire (SDQ) is a behavioural screening tool for children. The SDQ is increasingly used as the primary outcome measure in population health interventions involving children, but it is not preference based; therefore, its role in allocative economic evaluation is limited. The Child Health Utility 9D (CHU9D) is a generic preference-based health-related quality of-life measure. This study investigates the applicability of the SDQ outcome measure for use in economic evaluations and examines its relationship with the CHU9D by testing previously published mapping algorithms. The aim of the paper is to explore the feasibility of using the SDQ within economic evaluations of school-based population health interventions.
Methods
Data were available from children participating in a cluster randomised controlled trial of the school-based roots of empathy programme in Northern Ireland. Utility was calculated using the original and alternative CHU9D tariffs along with two SDQ mapping algorithms. t tests were performed for pairwise differences in utility values from the preference-based tariffs and mapping algorithms.
Results
Mean (standard deviation) SDQ total difficulties and prosocial scores were 12 (3.2) and 8.3 (2.1). Utility values obtained from the original tariff, alternative tariff, and mapping algorithms using five and three SDQ subscales were 0.84 (0.11), 0.80 (0.13), 0.84 (0.05), and 0.83 (0.04), respectively. Each method for calculating utility produced statistically significantly different values except the original tariff and five SDQ subscale algorithm.
Conclusion
Initial evidence suggests the SDQ and CHU9D are related in some of their measurement properties. The mapping algorithm using five SDQ subscales was found to be optimal in predicting mean child health utility. Future research valuing changes in the SDQ scores would contribute to this research.

Abundance and diversity of sedimentary bacterial communities in a coastal productive setting in the Western Irish Sea

The bacterial community composition and biomass abundance from a depositional mud belt in the western Irish Sea and regional sands were investigated by phospholipid ester-linked fatty acid profiling, denaturing gradient gel electrophoresis and barcoded pyrosequencing of 16S rRNA genes. The study area varied by water depth (12-111 m), organic carbon content (0.09-1.57% TOC), grain size, hydrographic regime (well-mixed vs. stratified), and water column phytodetrital input (represented by algal polyunsaturated PLFA). The relative abundance of bacterial-derived PLFA (sum of methyl-branched, cyclopropyl and odd-carbon number PLFA) was positively correlated with fine-grained sediment, and was highest in the depositional mud belt. A strong association between bacterial biomass and eukaryote primary production was suggested based on observed positive correlations with total nitrogen and algal polyunsaturated fatty acids. In addition, 16S rRNA genes affiliated to the classes Clostridia and Flavobacteria represented a major proportion of total 16S rRNA gene sequences. This suggests that benthic bacterial communities are also important degraders of phytodetrital organic matter and closely coupled to water column productivity in the western Irish Sea.

Validated Cfd Study of Indoor Environmental Conditions in a Highly Glazed , Cross-Ventilated Meeting Room

This paper investigates the environmental conditions inside a highly-glazed cross-ventilated meeting room. A 3D computational fluid dynamics (CFD) model of an indoor environment is developed with the support of the field measurements performed in a normally operating room. The work presented here follows the steps of the formal calibration methodology for the development of CFD models of naturally ventilated environments. This paper utilises the calibration methodology in order to predict environmental conditions within the highly-glazed cross-ventilated room occupied by people. The CFD model is verified and validated with field measurements performed in an operating building. Moreover, parametric analysis determines the most influential boundary conditions on indoor air temperatures and air speeds

Cuidar da pessoa com esquizofrenia em processo de reabilitação psicossocial

Este ensino clínico permitiu-nos prestar cuidados de enfermagem especializados a 16 homens com esquizofrenia em processo de reabilitação psicossocial. Na sua maioria são: adultos, solteiros, da região sul de Portugal, com uma média de 9 anos de escolaridade, com história de consumo de substâncias (álcool, tabaco, haxixe, cocaína, heroína e anfetaminas), institucionalizados na Casa de Saúde do Telhal (CST) há mais de 11 anos. Todos apresentam diagnósticos de enfermagem das várias dimensões do adoecer, com exceção da dimensão comportamental excitatória, sendo os de maior prevalência: “Conhecimento sobre Processo de doença/Cuidados na doença/Tratamento, Não Demonstrado”; Cognição, Comprometida”; “Processo Social, Alterado”; “Autoestima, Diminuída”. Foram desenvolvidos 4 programas de intervenção: consulta de enfermagem de saúde mental e psiquiatria (CESMP); atelier de estimulação cognitiva (AEC); programa de desenvolvimento de competência intrapessoais, interpessoais e profissionais (PDCIIP); programa de psicoeducação (SABER+). A satisfação global com os programas foi superior a 7 (numa escala de 1 a 10) e os resultados que foram percebidos pela maioria dos reabilitandos situaram-se acima das suas expectativas iniciais. De uma forma geral, todos registaram ganhos: no desempenho cognitivo (em particular os que beneficiaram do AEC); na adaptação psicossocial – nomeadamente ao nível do insight; os reabilitandos que beneficiaram do programa SABER+ melhoraram ainda os comportamentos demonstrados de aceitação do estado de saúde; no bem-estar psicológico – nomeadamente ao nível da autoestima (sobretudo os que beneficiaram da CESMP e/ou do PDCIIP), dos afetos positivos e dos comportamentos de motivação; nos vários domínios da qualidade de vida (QdV) medidos pelo WHOQOL-Bref em particular o domínio ambiental; todos elevaram o seu nível de conhecimentos nos 3 eixos em que que se estruturou o programa de psicoeducação (processo da doença, cuidados na doença, tratamento da doença); na adesão à medicação, sobretudo os que integraram o programa de psicoeducação, contudo todos tendem a necessitar de ajuda parcial para conseguir demonstrar conhecimento no cumprimento do esquema terapêutico e estão envolvidos em treinos supervisionados de preparação e autoadministração; ABSTRACT: This clinical training allowed us to provide skilled nursing care to 16 men with schizophrenia in a psychosocial rehabilitation setting. Most of these individuals are: adults, singles, from the southern region of Portugal, with an average of 9 years of schooling, with a history of substance abuse (alcohol, tobacco, cannabis, cocaine, heroin and amphetamines), institutionalized in Casa de Saúde do Telhal (CST) for over 11 years. We find nursing diagnoses from all of the disease dimensions with the exception of excitatory behavioral dimension, being the most prevalent: "knowledge about disease process / care / treatment, not stated"; cognition, impaired", "social process, impaired”, “self-esteem, decreased". We developed 4 intervention programs: psychiatry and mental health nursing consultation (CESMP); atelier of cognitive stimulation (AEC); intrapersonal, interpersonal and professional competences training (PDCIIP); psychoeducation (SABER+). The overall satisfaction with the programs was above 7 (on a scale of 1 to 10) and the results noticed by most patients were above their initial expectations. All registered nursing results were: in cognitive performance (particularly those who benefited from the AEC); in psychosocial adaptation - especially in terms of insight; patients who benefited from the SABER+ program demonstrated improved further acceptance of their health condition, psychological well-being, particularly in terms of self-esteem (especially those who benefited from the CESMP and/or the PDCIIP), positive affects and motivation; in the different domains of quality of life (QoL) measured by WHOQOL-Bref in particular the environmental domain; every patients raised their level of knowledge in the 3 axes in which the psychoeducational program (SABER+) was structured (disease process, care and treatment); in medication adherence, especially those who benefited of the psychoeducational program, however all the patients tend to need partial help to demonstrate knowledge in meeting the therapeutic regimen and are involved in supervised training programs for preparation and self administration.
