Background/Aim: Although certain types of sedentary behaviour have been linked to
metabolic risk, prospective studies describing the links between sitting with incident diabetes
are scarce and often do not account for baseline adiposity. We investigate the associations
between context-specific sitting and incident diabetes in a cohort of mid-aged to older British
civil servants. Methods: Using data from the Whitehall II Study (n=4811), Cox proportional
hazards models (adjusted for age, sex, ethnicity, employment grade, smoking, alcohol intake,
fruit and vegetable consumption, self-rated health, physical functioning, walking and
moderate-to-vigorous physical activity, and BMI) were fitted to examine associations
between total sitting and context–specific sitting time (work, television (TV), non-TV leisure
time sitting at home) at Phase 5 (1997-99) and fasting glucose-defined incident diabetes up to
2011. Results: Total sitting (HR of top compared to the bottom group: 1.26; 95%CI: 1.00
to 1.62; p=0.01) and TV sitting (1.33; 1.03 to1.88; p=0.05) showed associations with
incident diabetes; once BMI was included in the model these associations were attenuated for
both total sitting (1.19; 0.92 to 1.55; p=0.22) and TV sitting (1.31; 0.96 to 1.76; p=0.14).
Conclusions: We found limited evidence linking sitting and incident diabetes over 13 years
in this cohort of civil servants.
