Abstract:
Objective To explore the interaction between vitamin D(VD)and hemoglobin A1c(HbA1c)and its relationship with type 2 diabetes mellitus(T2DM)combined with osteoporosis(OP).Methods A total of 228 T2DM patients admitted to our hospital from February 2020 to April 2023 were selected and divided into OP group(n=65),osteopenia group(n=89)and T2DM group(n=74)according to the standard deviation of bone mineral density(BMD)decline.Logistic regression was used to analyze the relationship of 25-hydroxyvitamin D[25(OH)D]and HbA1c with OP.Restricted cubic spline model was used to analyze the dose-response relationship of 25(OH)D and HbA1c with OP in different genders.Results DM duration,fasting plasma glucose(FPG),C-telopeptide of type Ⅰ collagen,fasting insulin(FIns)and 2 hIns in the T2DM,osteopenia and OP groups were increased(P<0.05),while osteocalcin,25(OH)D,lumbar L1~L4,BMD of femoral neck and its proximal end,and total hip were decreased(P<0.05).The age and HbA1c in OP group were higher than those in T2DM and osteopenia groups(P<0.05),and the proportion of taking calcium preparations was lower than that in T2DM group(P<0.05).Logistic regression analysis showed that after adjusting for confounding factors,serum 25(OH)D(OR 0.145,95%CI 0.036~0.204)and HbA1c(OR 1.108,95%CI 1.013~1.140)were influencing factors of OP in T2DM patients.There was no nonlinear dose-response relationship between 25(OH)D,HbA1c and OP both in male and female T2DM patients.There were multiplication and additive interactions between serum 25(OH)D and HbA1c(P<0.05).Conclusions There is a multiplicative and additive interaction between serum 25(OH)D and HbA1c,both of which are risk factors for concurrent OP in T2DM patients.
