Sex differences in the reciprocal relationship between glycemic control and depressive symptoms among older adults with diabetes: Using a nationwide population-based sample

AimAs 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.MethodsWave 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.ResultsHbA1c 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 (beta = 0.18, SD = 0.05, P = 0.001). The path from HbA1c levels (W1) to depressive symptoms (W2) was positively statistically significant in females (beta = 0.12, SD = 0.06, P = 0.032).ConclusionsEarly 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.

Automated summary

As life expectancy increases worldwide, the prevalence and disease burden of diabetes in older adults are also increasing. This study aimed to investigate sex differences in the reciprocal relationship between glycemic control and depressive symptoms in older adults with diabetes. The results showed that early glycemic control and depressive symptoms were significant factors influencing later glycemic control and depressive symptoms. The relationship between glycemic control and depressive symptoms varied by sex.
