The impact of depressive mood and obesity on postprandial glucose levels after a standardized meal

Depression, obesity and T2D are growing healthcare and societal burdens worldwide. Several studies showed that there are relationships between these burdens. T2D often coincides with depression and vice versa, whereas elevated glucose levels can indicate T2D. Current study focuses on depressive mood, postprandial- and glucose levels. This cross-sectional cohort study utilized secondary, quantitative data from the Netherlands Epidemiology of Obesity (NEO) study (N = 6671), which included a meal challenge. The Inventory of Depressive Symptoms (IDS), was used to assess depressive mood. It was expected that depressive mood predicts elevated postprandial- and fasting glucose levels. Sex, BMI and Total Body Fat were expected to be moderators. Depressive mood significantly predicted elevated postprandial- and fasting glucose levels, before adding covariates other than age and sex. Sex, BMI and TBF all significantly moderated the associations between depressive mood and elevated...Show moreDepression, obesity and T2D are growing healthcare and societal burdens worldwide.

Sex, BMI and Total Body Fat were expected to be moderators. Depressive mood significantly predicted elevated postprandial- and fasting glucose levels, before adding covariates other than age and sex. Sex, BMI and TBF all significantly moderated the associations between depressive mood and elevated postprandial- and fasting glucose. The effect of depressive mood on postprandial glucose, but not fasting glucose, was stronger in females than in males, with B = .017, p < .001 and B = 007, p < .001, respectively. Subjects with depressive mood are more at risk for developing IGM, IFG, and ultimately T2D. Women are more at risk than men, whereas excess weight also seems a risk factor for elevated glucose levels. It is suggested that future research focusses on the impact of confounding variables and depressive symptoms by itself, to more accurately study the effect of depression on IGM, IFG and T2D.Show less
