To determine whether there were differences in depressed mood between overweight/obese men with and without type 2 diabetes (T2DM) and to examine any associations between depressed mood, physical functioning, and glycaemic control in overweight/obese men with and without T2DM.


Fifty seven overweight/obese men with (n = 19, age = 54.2 ± 7.4 yrs, BMI = 32.3 ± 6.7 kg⋅m-2) and without T2DM (n = 38, age = 51.1 ± 6.8 yrs, BMI = 29.9 ± 4.5kg⋅m-2, p > 0.05 between groups) participated. The men completed measures of depressed mood and health-related quality of life (HRQL) and underwent the following assessments: fasting blood lipids and glucose, HbA1c, anthropometric measurements, VO2peak, muscle strength, and physical function.


Compared to men without T2DM, men with T2DM had higher depressed mood (p = 0.05, η2 = 0.07), as well as lower perceived general health (p < .01, η2 = 0.24) and social functioning (p = .01, η2 = 0.10). Men with T2DM also had lower VO2peak (21.8 ± 5.3 versus 25.8 ± 5.4 ml⋅kg-1⋅min-1, p < .01, η2 = 0.11) and muscle strength (3.3 ± 0.8 versus 3.7 ± 0.7 kg⋅kg-1, p = 0.08, η2 = 0.06), as well as being slower to complete physical performance tasks (27.2 ± 5.2 versus 24.2 ± 2.8 sec, p < 0.01, η2 = 0.13). In those with T2DM, depressed mood was highly correlated with most HRQL subscales. For the combined cohort, depressed mood was correlated with fasting glucose (r = 0.31, p = 0.012) but not the functional measures.


Men with T2DM have higher levels of depressed mood compared to men without T2DM. Glycaemic control, but not functional capacities, is associated with depressed mood in the study cohort.
