Abstract
This cross-sectional study aimed to examine the associations among self-reported sitting time (ST), transtheoretical model (TTM) based on exercise behavior change, and glycemic and weight control in Japanese adults with type 1 diabetes (T1D). Forty-two adults (age, 44.0 (33.3–56.8) years) with uncomplicated T1D answered questions regarding their lifestyles, including ST per day, and TTM using self-administered questionnaires. The glycated hemoglobin (HbA1c) level correlated with age and ST (p < 0.05, p < 0.01, respectively), whereas body mass index correlated with duration of T1D and TTM (p < 0.05, p < 0.01, respectively). Logistic regression analysis showed that poor glycemic control (HbA1c, >7%) was associated with ST (odds ratio, 3.53 (95% confidence interval, 1.54–8.11), p < 0.01). In addition, the cut-off points for quartiles of ST were 4.6, 6.0, and 8.0 h/day, and the HbA1c level in the lowest quartile was 15% lower than that in the highest quartile (p < 0.01). Although further studies with larger samples are needed, these results implied that expanded self-reported ST might be related to poor glycemic control in Japanese T1D adults, most of whom were lean, young and middle-aged, regardless of TTM based on exercise behavior change.
Highlights
Sedentary behavior, which is mostly the same as sitting time (ST) or reclining, is a primary indication for the decrease of physical activity (PA) [1]
transtheoretical model (TTM) based on exercise behavior change is an important factor for diabetic patients performing exercise

Summary
Sedentary behavior, which is mostly the same as sitting time (ST) or reclining, is a primary indication for the decrease of physical activity (PA) [1]. Management of T1D is developing at a fast pace through various devices, medication, and nutrition therapy, and Japanese individuals with T1D receive various treatments in accordance with their dietary habits, culture, residential environment, and physical status, which differ from those of other countries. It is uncertain whether results from Western patients [8,9,10,11,12] can be applied to Japanese individuals with T1D. We conducted this study to examine the association among ST, TTM based on exercise behavior change, and glycemic and weight control in Japanese adults with T1D
