Uptake and factors that influence the use of ‘sit less, move more’ occupational intervention strategies in Spanish office employees

Background Little is known about the types of ‘sit less, move more’ strategies that appeal to office employees, or what factors influence their use. This study assessed the uptake of strategies in Spanish university office employees engaged in an intervention, and those factors that enabled or limited strategy uptake. Methods The study used a mixed method design. Semi-structured interviews were conducted with academics and administrators (n = 12; 44 ± 12 mean SD age; 6 women) at three points across the five-month intervention, and data used to identify factors that influenced the uptake of strategies. Employees who finished the intervention then completed a survey rating (n = 88; 42 ± 8 mean SD age; 51 women) the extent to which strategies were used [never (1) to usually (4)]; additional survey items (generated from interviewee data) rated the impact of factors that enabled or limited strategy uptake [no influence (1) to very strong influence (4)]. Survey score distributions and averages were calculated and findings triangulated with interview data. Results Relative to baseline, 67% of the sample increased step counts post intervention (n = 59); 60% decreased occupational sitting (n = 53). ‘Active work tasks’ and ‘increases in walking intensity’ were the strategies most frequently used by employees (89% and 94% sometimes or usually utilised these strategies); ‘walk-talk meetings’ and ‘lunchtime walking groups’ were the least used (80% and 96% hardly ever or never utilised these strategies). ‘Sitting time and step count logging’ was the most important enabler of behaviour change (mean survey score of 3.1 ± 0.8); interviewees highlighted the motivational value of being able to view logged data through visual graphics in a dedicated website, and gain feedback on progress against set goals. ‘Screen based work’ (mean survey score of 3.2 ± 0.8) was the most significant barrier limiting the uptake of strategies. Inherent time pressures and cultural norms that dictated sedentary work practices limited the adoption of ‘walk-talk meetings’ and ‘lunch time walking groups’. Conclusions The findings provide practical insights into which strategies and influences practitioners need to target to maximise the impact of ‘sit less, move more’ occupational intervention strategies.

Self-reported sitting time and physical activity: interactive associations with mental well-being and productivity in office employees

Abstract Background: Little is known about how sitting time, alone or in combination with markers of physical activity (PA), influences mental well-being and work productivity. Given the need to develop workplace PA interventions that target employees’ health related efficiency outcomes; this study examined the associations between self-reported sitting time, PA, mental well-being and work productivity in office employees. Methods: Descriptive cross-sectional study. Spanish university office employees (n = 557) completed a survey measuring socio-demographics, total and domain specific (work and travel) self-reported sitting time, PA (International Physical Activity Questionnaire short version), mental well-being (Warwick-Edinburg Mental Well-Being Scale) and work productivity (Work Limitations Questionnaire). Multivariate linear regression analyses determined associations between the main variables adjusted for gender, age, body mass index and occupation. PA levels (low, moderate and high) were introduced into the model to examine interactive associations. Results: Higher volumes of PA were related to higher mental well-being, work productivity and spending less time sitting at work, throughout the working day and travelling during the week, including the weekends (p < 0.05). Greater levels of sitting during weekends was associated with lower mental well-being (p < 0.05). Similarly, more sitting while travelling at weekends was linked to lower work productivity (p < 0.05). In highly active employees, higher sitting times on work days and occupational sitting were associated with decreased mental well-being (p < 0.05). Higher sitting times while travelling on weekend days was also linked to lower work productivity in the highly active (p < 0.05). No significant associations were observed in low active employees. Conclusions: Employees’ PA levels exerts different influences on the associations between sitting time, mental well-being and work productivity. The specific associations and the broad sweep of evidence in the current study suggest that workplace PA strategies to improve the mental well-being and productivity of all employees should focus on reducing sitting time alongside efforts to increase PA.

Patterns of impact resulting from a 'sit less, move more' web-based program in sedentary office employees

Purpose Encouraging office workers to ‘sit less and move more’ encompasses two public health priorities. However, there is little evidence on the effectiveness of workplace interventions for reducing sitting, even less about the longer term effects of such interventions and still less on dual-focused interventions. This study assessed the short and mid-term impacts of a workplace web-based intervention (Walk@WorkSpain, W@WS; 2010-11) on self-reported sitting time, step counts and physical risk factors (waist circumference, BMI, blood pressure) for chronic disease. Methods Employees at six Spanish university campuses (n=264; 42±10 years; 171 female) were randomly assigned by worksite and campus to an Intervention (used W@WS; n=129; 87 female) or a Comparison group (maintained normal behavior; n=135; 84 female). This phased, 19-week program aimed to decrease occupational sitting time through increased incidental movement and short walks. A linear mixed model assessed changes in outcome measures between the baseline, ramping (8 weeks), maintenance (11 weeks) and followup (two months) phases for Intervention versus Comparison groups.A significant 2 (group) × 2 (program phases) interaction was found for self-reported occupational sitting (F[3]=7.97, p=0.046), daily step counts (F[3]=15.68, p=0.0013) and waist circumference (F[3]=11.67, p=0.0086). The Intervention group decreased minutes of daily occupational sitting while also increasing step counts from baseline (446±126; 8,862±2,475) through ramping (+425±120; 9,345±2,435), maintenance (+422±123; 9,638±3,131) and follow-up (+414±129; 9,786±3,205). In the Comparison group, compared to baseline (404±106), sitting time remained unchanged through ramping and maintenance, but decreased at follow-up (-388±120), while step counts diminished across all phases. The Intervention group significantly reduced waist circumference by 2.1cms from baseline to follow-up while the Comparison group reduced waist circumference by 1.3cms over the same period. Conclusions W@WSis a feasible and effective evidence-based intervention that can be successfully deployed with sedentary employees to elicit sustained changes on “sitting less and moving more”.

Baixem de les tarimes i connectem: recerca en història medieval i innovació docent

We would like to introduce our group of research, [CONTRA TAEDIUM], created by professionals from different fields, that have contributed in this article. Our purpose is to expose our reflections based on our own experiences, not only in research, but also in teaching. We propose new forms of writing history in order to understand the dairy life of the women and men of the past, from birth to death. We would like to point out that interacting all types of sources is essential to understand our history. But, what really makes sense is to bring our students in the historical methodology and involve them in their education. Moreover, it is necessary to design new teaching materials using the new technologies, although it requires team-work and a great, but satisfying, effort

Expressional regulation of key hepatic enzymes of intermediary metabolism in European seabass (Dicentrarchus labrax) during food deprivation and refeeding

We hypothesized that the analysis of mRNA level and activity of key enzymes in amino acid and carbohydrate metabolism in a feeding/fasting/refeeding setting could improve our understanding of how a carnivorous fish, like the European seabass (Dicentrarchus labrax), responds to changes in dietary intake at the hepatic level. To this end cDNA fragments encoding genes for cytosolic and mitochondrial alanine aminotransferase (cALT; mALT), pyruvate kinase (PK), glucose 6-phosphate dehydrogenase (G6PDH) and 6-phosphogluconate dehydrogenase (6PGDH) were cloned and sequenced. Measurement of mRNA levels through quantitative real-time PCR performed in livers of fasted seabass revealed a significant increase in cALT (8.5-fold induction)while promoting a drastic 45-fold down-regulation of PK in relation to the levels found in fed seabass. These observations were corroborated by enzyme activity meaning that during food deprivation an increase in the capacity of pyruvate generation happened via alanine to offset the reduction in pyruvate derived via glycolysis. After a 3-day refeeding period cALT returned to control levels while PK was not able to rebound. No alterations were detected in the expression levels of G6PDH while 6PGDH was revealed to be more sensitive specially to fasting, as confirmed by a significant 5.7-fold decrease in mRNA levels with no recovery after refeeding. Our results indicate that in early stages of refeeding, the liver prioritized the restoration of systemic normoglycemia and replenishment of hepatic glycogen. In a later stage, once regular feeding is re-established, dietary fuel may then be channeled to glycolysis and de novo lipogenesis.

Efecto del volumen radicular sobre el crecimiento de Acacia dealbata Link. en vivero y en terreno en el secano de la Región del Biobío, Chile

Entre las especies arbóreas cultivadas en Chile, Acacia dealbata Link. se destaca por su rápido crecimiento y supervivencia en climas con marcado déficit hídrico y suelos altamente degradados. Aun cuando proporciona múltiples productos y servicios, la mayor parte de la investigación se ha centrado caracterizar su capacidad invasora, y poco se conoce respecto a su crecimiento durante los primeros años en terreno, escaseando antecedentes respecto efecto de la modificación de las prácticas silvícolas durante la producción y establecimiento de plantas. Por ello, este estudio analiza el efecto de la modificación del volumen radicular sobre el crecimiento durante la viverización, y la supervivencia y crecimiento culminadas la primera y segunda temporada en terreno. Finalizada la viverización resultó significativo el efecto del volumen radicular sobre el DAC y la altura total (P<0,05), los mayores valores se obtuvieron en plantas producidas con volumen de 100 cm³. Los volúmenes más altos presentaron los mayores índices de esbeltez y de Dickson (P<0.05), mientras que los mejores índices tallo/raíz se observaron con los volúmenes de 56 y 24 cm³ (P<0,05). Culminadas la primera y segunda temporada de crecimiento el efecto del volumen sobre la supervivencia resultó no significativo. Luego de la segunda temporada, se destacó el mayor incremento corriente anual en DAC del tratamiento de 24 cm³ (5,53 ± 1,63 mm). Luego de ambas temporadas se destacó una tendencia a la igualación en altura entre los tratamientos de 100, 80 y 24 cm³, el mayor crecimiento absoluto y relativo se observó en el tratamiento de 24 cm³.

DETERMINACIÓN DE MEDIOS DE CULTIVO Y PH PARA LA MASIFICACIÓN in vitro DE CEPAS DE Suillus luteus Aubl. ASOCIADAS A Pinus radiata D. Don Y Scleroderma citrinum Pers. ASOCIADAS A Eucalyptus globulus Labill. DE LA REGIÓN DEL BIOBÍO, CHILE

El uso de agentes biológicos en la producción en vivero ha aflorado como un elemento que permite no sólo mejorar la calidad morfológica y fisiológica de las plantas, sino que también posibilitar un mayor éxito en el ámbito silvicultural de una plantación. Estos agentes biológicos requieren de un ambiente óptimo para crecer, asociarse y reproducirse. El objetivo de este estudio fue determinar la dependencia del pH y el medio de cultivo en el crecimiento in vitro de distintas cepas de Suillus luteus y Scleroderma citrinum asociadas a Pinus radiata y Eucalyptus globulus, respectivamente. El estudio se realizó en condiciones controladas de temperatura y humedad, disponiendo los inóculos en placas Petri con diferentes medios cultivo, evaluando parámetros de crecimiento y biomasa a los 38 días para S. luteus y 105 días para S. citrinum. Los resultados indican que tanto el medio de cultivo, el pH del medio, así como las cepas de cada especie estudiada, son determinantes en las respuestas de crecimiento de los hongos ectomicorrícicos in vitro evaluados. Las cepas de S. luteus se desarrollaron adecuadamente en un medio de cultivo con abundancia de nutrientes (BAF, MMN) como en baja presencia de ellos (EMA), y con pH más bien ácido (4,8 y 5,8). Por otro lado, las cepas de S. citrinum presentaron, para los mismos ambientes, un desarrollo inferior y lento, no obstante, la cepa Sc8 se reprodujo de forma óptima y rápida bajo un medio de cultivo BAF y con un pH moderadamente ácido de 5,8.

Utilização da vitamina D3 e seus metabólitos na alimentação de frangos de corte sobre parâmetros imunológicos e morfometria intestinal

Os efeitos da suplementação da vitamina D3 e de seus diferentes metabólitos foram avaliados na resposta imune e na morfometria intestinal de frangos de corte. Foram utilizados 952 frangos de corte de um dia de idade, distribuídos em um delineamento inteiramente casualizado, com quatro tratamentos, sete repetições e 34 aves por unidade experimental. Os tratamentos foram constituídos por quatros diferentes fontes de vitamina D3: colecalciferol (D3), 25-hidroxicolecalciferol (25(OH)D3), 1,25-dihidroxicolecalciferol (1,25(OH)2D3) e 1α-hidroxicolecalciferol (1α(OH)D3). As diferentes fontes foram incluídas na dieta, fornecendo 2000 e 1600 UI de vitamina D, nas fases pré-inicial, inicial e de crescimento, respectivamente. O peso relativo do intestino delgado diferiu entre os tratamentos aos 7, 21 e 42 dias e o peso relativo do fígado somente aos 42 dias de idade. Os demais órgãos e parâmetros imunológicos avaliados (peso dos órgãos linfóides, reação de hipersensibilidade cutânea basofílica, avaliação da atividade de macrófagos, dosagem de nitrito e perfil heterofilo: linfócito foram similares entre os animais alimentados com os diferentes metabólitos. Houve efeito (P<0,05) dos diferentes metabólitos da vitamina D3 sobre o comprimento dos vilos de jejuno e íleo aos sete dias, diferindo entre os animais alimentados com 1,25(OH)2D3 e 1α(OH)D3 para jejuno e 1,25(OH)2D3 e vitamina D3 para íleo (P<0,05). Para as demais fases não foi observado influência (P>0,05) dos tratamentos. Os parâmetros imunológicos não foram afetados pelos diferentes metabólitos de vitamina D. Os diferentes metabólitos de vitamina D afetaram positivamente a morfometria intestinal na altura de vilo na fase inicial, sendo os melhores resultados obtido pelos animais alimentados com 1,25(OH)2D3, contudo os parâmetros imunológicos foram similares entre os metabólitos estudados.
