Physio-cognitive decline syndrome among middle-aged diabetes patients: Handgrip strength significantly correlates with glycaemic control and cognitive score

Aims: To investigate the correlation between glycaemic control with component of Physio-Cognitive Decline Syndrome (PCDS) and among each component of PCDS itself. Methods: A cross sectional study was conducted (January 2021–November 2022) at Dr. Cipto Mangunkusumo Hospital, Jakarta, Indonesia on consecutively recruited T2DM outpatients aged 40–59 years old. Data on the latest three months HbA1c, hand grip strength (HGS), usual gait speed (GS), and Indonesian Montreal Cognitive Assessment (MoCA-Ina) were evaluated. Pearson or Spearman's test was used to analyse the correlations. Results: There were 133 subjects with median age 53 (40–59) years. The PCDS was found in 48.1 % subjects, of which 64.1 % with uncontrolled glycaemia. Significant correlations were found between HGS and HbA1c (r = −0.24, R² = 0.06, p < 0.01) and MoCA-Ina score (r = 0.21, R² = 0.04, p < 0.05). Conclusion: The higher HbA1c and the lower MoCA-Ina score, the weaker handgrip strength was.
