ABSTRACT
INTRODUCTION: Workplaces are important settings for implementation of smoke-free environments. In this study, we follow a medical production company with 677 employees that implemented one of the most stringent tobacco policies legally possible in Denmark - smoke-free work hours - which means that employees are not allowed to smoke during work time. This study explores tobacco use restrictions during work hours regarding readiness of implementation, focusing specifically on middle managers' perceptions and considerations, as well as their perceived responsibility in enforcing these. METHODS: A case study is presented. Two focus groups of 10 middle managers were conducted, seven months before smoke-free work hours were implemented. The facilitators used open-ended questions, which consisted of a structured section with specific themes related to the implementation of smoke-free work hours. Focus groups were recorded, transcribed, and analyzed thematically. RESULTS: We identified five main themes: 1) Benefits of the new policy due to better health, lower sickness-related absences, increased productivity, and improved branding value; 2) Social interactions across smoking status; 3) Smoking is a private matter with ethical dimensions; 4) The role of middle managers and concerns about enforcement; and 5) Limited experience with resistance from the smoking employees. CONCLUSIONS: The findings suggest that workplaces in the preparation phase should ensure that: 1) The middle managers gain training on how to talk with employees about smoking cessation; 2) The middle managers are equipped to handle the new policy and have a joint vision and understanding of why and how they should enforce it; and 3) Room is made for discussions on resistance and enforcement-related challenges as well as ethical issues.
ABSTRACT
AIM/HYPOTHESIS: Little is known about the relative roles of physical activity energy expenditure (PAEE) and cardiorespiratory fitness (CRF) as determinants of glucose regulation. The aim of this study was to examine the associations of PAEE and CRF with markers of glucose metabolism, and to test the hypothesis that CRF modifies the association between PAEE and glucose metabolism. METHODS: We analysed cross-sectional data from 755 adults from the Danish ADDITION-PRO study. On the basis of OGTT results, participants without known diabetes were classified as having normal glucose tolerance, isolated impaired fasting glycaemia (i-IFG), isolated impaired glucose tolerance (i-IGT), combined IFG + IGT or screen-detected diabetes mellitus. Markers of insulin sensitivity and beta cell function were determined. PAEE was measured using a combined heart rate and movement sensor. CRF (maximal oxygen uptake) was estimated using a submaximal 8 min step test. The associations were examined by linear regression analysis. Results were adjusted for relevant confounders. RESULTS: PAEE and CRF were reduced in individuals with i-IGT, combined IFG + IGT and screen-detected diabetes mellitus, but were not significantly different in individuals with i-IFG compared with those with normal glucose tolerance. When adjusting CRF for PAEE and vice versa, PAEE and CRF were both associated with lower fasting and 2 h insulin and higher peripheral insulin sensitivity. CRF was additionally associated with lower fasting and 2 h glucose and higher insulin sensitivity and beta cell function. There was no interaction between CRF and PAEE for any markers of glucose metabolism. CONCLUSIONS/INTERPRETATION: Only CRF, not PAEE, appears to be independently associated with plasma glucose levels and beta cell function, suggesting that CRF may be particularly important for glycaemic control.
