[참여대학원생 강경아] Sex differences in the reciprocal relationship between glycemic control and depressive symptoms among older adults with diabetes: Using a nationwide population-based sample
Abstract
Aim
As life expectancy increases worldwide, the prevalence and the disease burden of diabetes in older adults are also increasing. This study aimed to examine sex differences in the reciprocal relationship between glycemic control and depressive symptoms among older adults with diabetes by using longitudinal data at two timepoints.
Methods
Wave 1 (W1, 2016–2017) and wave 2 (W2, 2018–2019) data from the Korean Frailty and Aging Cohort Study were used. Finally, 416 older adults with diabetes who satisfied the inclusion criteria were analyzed (215 males, 201 females). The reciprocal relationship between depressive symptoms and glycosylated hemoglobin A1c (HbA1c) levels was examined using a cross-lagged panel model.
Results
HbA1c levels and depressive symptoms at earlier time points were the most significant factors contributing to HbA1c levels and depressive symptoms at later timepoints. The relationship between HbA1c level and depressive symptoms differed according to sex. The cross-path from depressive symptoms (W1) to HbA1c levels (W2) was positively statistically significant in males (β = 0.18, SD = 0.05, P = 0.001). The path from HbA1c levels (W1) to depressive symptoms (W2) was positively statistically significant in females (β = 0.12, SD = 0.06, P = 0.032).
Conclusions
Early management of blood glucose levels and depressive symptoms is important in older adults with diabetes. Moreover, glycemic control through social activities in the community could be effective in relieving depressive symptoms in older females with diabetes, and managing depressive symptoms and glucose levels together could be effective in glycemic control in older males with diabetes.
