Association between hedonic hunger and glycemic control in non-obese and obese patients with type 2 diabetes.

AIMS/INTRODUCTION: Higher hedonic hunger has been observed in obese individuals compared with those without obesity, but little is known about its association with glycemic management. We aimed to examine the association between hedonic hunger and glycemic control in non-obese and obese patients with type 2 diabetes.

MATERIALS AND METHODS

Between April and November 2016, a total of 211 type 2 diabetes patients who underwent comprehensive diabetes assessments at a university-affiliated hospital were recruited into two groups according to body mass index: non-obese (body mass index 18.5-24.9 kg/m ) and obese (body mass index ≥30 kg/m ) groups. All participants completed the Chinese version of the Power of Food Scale (PFS) for assessment of hedonic hunger. Good glycemic control was defined as glycated hemoglobin <7.0%.

RESULTS

Compared with the non-obese group, the obese group showed higher PFS aggregated and subscale 'food available' scores (both P < 0.05). After adjustment for age, sex, disease duration of diabetes and insulin use, there were positive associations of glycated hemoglobin with PFS aggregated, subscale 'food available' and 'food present' scores in the obese group (all P for trend <0.05). The PFS aggregated score was negatively associated with good glycemic control in obese type 2 diabetes patients after adjustment using logistic regression analysis (adjusted odds ratio 0.42, 95% confidence interval 0.20-0.91, P = 0.027). By contrast, such associations were not observed in non-obese type 2 diabetes patients.

CONCLUSIONS

Hedonic hunger had an independent and inverse association with good glycemic control in obese Chinese patients with type 2 diabetes, but not in their counterparts without obesity.
