Abstract
Objectively assessed sedentary time and type 2 diabetes mellitus: a case–control study
Highlights
To the Editor: There is some evidence to suggest detrimental, linear associations between objectively assessed sedentary time and various metabolic risk factors [1, 2], it remains unclear if these associations are independent of moderate to vigorous physical activity [3, 4]
Each diabetic patient was matched with two healthy controls based on age, sex and income
The accelerometer provides a measure of the frequency, intensity and duration of physical activity and allows classification of activity levels as sedentary, light, moderate and vigorous
Summary
To the Editor: There is some evidence to suggest detrimental, linear associations between objectively assessed sedentary time and various metabolic risk factors [1, 2], it remains unclear if these associations are independent of moderate to vigorous physical activity [3, 4]. The effects of sedentary behaviour on health might be more apparent in clinical populations and the elderly, the majority of research in this area has been conducted in healthy participants, which might partly explain inconsistencies in the findings. The aim of this study was to compare objectively assessed levels of sedentary and physical activity in type 2 diabetic patients and age matched healthy controls. The accelerometer provides a measure of the frequency, intensity and duration of physical activity and allows classification of activity levels as sedentary, light, moderate and vigorous. All analyses were conducted using SPSS version 21 (IBM, Armonk, NY, USA)
