Sit-to-stand height-adjustable desks (HAD) may promote workplace standing, as long as workers use them on a regular basis. The aim of this study was to investigate (i) how common HAD in German desk-based workers are, and how frequently HADs are used, (ii) to identify sociodemographic, health-related, and psycho-social variables of workday sitting including having a HAD, and (iii) to analyse sociodemographic, health-related, and psycho-social variables of users and non-users of HADs.
A cross-sectional sample of 680 participants (51.9% men; 41.0 ± 13.1 years) in a desk-based occupation was interviewed by telephone about their occupational sitting and standing proportions, having and usage of a HAD, and answered questions concerning psycho-social variables of occupational sitting. The proportion of workday sitting was calculated for participants having an HAD (n = 108) and not-having an HAD (n = 573), as well as for regular users of HAD (n = 54), and irregular/non-users of HAD (n = 54). Linear regressions were conducted to calculate associations between socio-demographic, health-related, psychosocial variables and having/not having an HAD, and the proportion of workday sitting. Logistic regressions were executed to examine the association of mentioned variables and participants' usage of HADs.
Sixteen percent report that they have an HAD, and 50% of these report regular use of HAD. Having an HAD is not a correlate of the proportion of workday sitting. Further analysis restricted to participants having available a HAD highlights that only the 'perceived advantages of sitting less' was significantly associated with HAD use in the fully adjusted model (OR 1.75 [1.09; 2.81], p < 0.05).
The present findings indicate that accompanying behavioral action while providing an HAD is promising to increase the regular usage of HAD. Hence, future research needs to address the specificity of behavioral actions in order to enhance regular HAD use, and needs to give more fundamental insights into these associations.
坐站两用高度可调节办公桌（HAD）只要员工经常使用，就可能促进工作场所的站立。本研究的目的是调查：（i）德国伏案工作者中HAD的普及程度以及使用频率；（ii）确定工作日坐姿的社会人口学、健康相关和心理社会变量，包括是否拥有HAD；（iii）分析HAD使用者和非使用者的社会人口学、健康相关和心理社会变量。
通过电话采访了680名从事伏案工作的参与者（51.9%为男性；年龄41.0±13.1岁），询问他们职业中的坐立比例、是否拥有和使用HAD，并回答有关职业坐姿心理社会变量的问题。计算了拥有HAD的参与者（n = 108）和未拥有HAD的参与者（n = 573），以及HAD的经常使用者（n = 54）和不经常/不使用者（n = 54）的工作日坐姿比例。进行线性回归以计算社会人口学、健康相关、心理社会变量与拥有/未拥有HAD以及工作日坐姿比例之间的关联。进行逻辑回归以检验上述变量与参与者使用HAD之间的关联。
16%的人报告他们拥有HAD，其中50%的人报告经常使用HAD。拥有HAD与工作日坐姿比例无关。进一步对拥有HAD的参与者进行分析发现，在完全调整模型中，只有“减少坐姿的感知优势”与HAD的使用显著相关（OR 1.75 [1.09；2.81]，p < 0.05）。
目前的研究结果表明，在提供HAD时伴随行为行动有望增加HAD的经常使用。因此，未来的研究需要解决行为行动的特异性，以提高HAD的经常使用，并需要对这些关联给出更深入的见解。
