Glycemic qualification rate and frequency of self-monitoring blood glucose glycemic qualification rate and frequency of self-monitoring blood glucose (SMBG) in women with gestational diabetes mellitus (GDM)

Abstract

Aims: To explore the relationship between blood glucose (BG) control rate and self-monitoring blood glucose (SMBG) compliance of women with gestational diabetes mellitus (GDM).

Methods: Women with GDM (n = 309) were randomized to receive routine clinical prenatal care or additional online management. Follow-up visits were conducted every two weeks (noted here as T) from enrollment to delivery. SMBG records were used for the analysis.

Results: Both the intervention group and the control group had an increasing BG control rate and decreasing SMBG compliance during the whole follow-up period. Detailed data analysis on separate follow-up periods showed that the SMBG frequency was negatively correlated with the BG control rate in most Ts and that the BG control rate of T_n-1 was negatively correlated with the SMBG frequency of T_n in the adjacent T. Only in the intervention group was T₂ SMBG compliance not under the influence of the T₁ BG control rate.

Conclusions: Our data suggested that regardless of management approach, the BG control rate increased, and the SMBG frequency decreased as gestational weeks increased in women with GDM. Even in separate follow-up periods, the SMBG frequency was negatively correlated with the BG control rate both within one follow-up period and between two adjacent follow-up periods.
