Objective:To explore the effectiveness of blood glucose monitoring at different frequencies on the control of blood glucose in overweight/obese prediabetes population on the basis of health education, and to provide a basis for blood glucose monitoring and management in prediabetes population.Methods:A randomized controlled study was used. 90 prediabetes patients from the Physical Examination Center/Endocrine Clinic/Endocrine Ward of the First Affiliated Hospital of China Medical University from January to March 2021 were selected by continuous sampling method, and were randomly divided into the group A, B and C by lottery method, with 30 patients in each group, and the study period was 12 months. Group A, B and C received unified health education guidance at enrollment, 6-month follow-up, and 12-month follow-up. Group A underwent blood glucose monitoring every 6 months, group B underwent blood glucose monitoring every 3 months, group C underwent blood glucose monitoring every month. Recorded and compared the levels of glycated hemoglobin (HbA1c), fasting plasma glucose (FPG), 2-hour post-load blood glucose (2 hPG), and body mass index (BMI) of three groups at the time points of enrollment, 6-month follow-up, and 12-month follow-up.Results:There were 15 males and 15 females in the group A, 14 males and 16 females in the group B, 12 males and 18 females in the group C. The ages in the group A, B and C were (48.37 ± 10.80), (49.20 ± 9.25) and (44.77 ± 12.28) years old respectively. At the time point of 12-month follow-up, the HbA1c in the group A, B and C were (6.01 ± 0.36)%, (5.82 ± 0.35)% and (5.64 ± 0.27)%, the difference was significant ( F=9.72, P<0.05); the FPG in the group A, B and C were (5.64 ± 0.88), (5.05 ± 0.53) and (4.98 ± 0.48)mmol/L, the difference was significant ( F=9.23, P<0.05); the 2 hPG in the group A, B and C were (9.38 ± 1.23), (8.23 ± 0.72) and (7.71 ± 0.86) mmol/L, the difference was significant ( F=23.89, P<0.05); the BMI in the group A, B and C were (28.52 ± 4.24), (27.02 ± 2.67) and (25.56 ± 1.34) kg/m 2, the difference was significant ( F=7.37, P<0.05). Conclusions:On the basis of health education, compared with the routine blood glucose monitoring once every six months, blood glucose monitoring once every three months and once every month can improve the blood glucose control and BMI level of overweight/obese young and middle-aged people with prediabetes, and provide a basis for seeking an effective and economic blood glucose monitoring mode in clinical practice.
RÉSUMÉ
Objective To investigate the premature spontaneous ovulation rates in in vitro fertilization-embryo transfer (IVF-ET) cycles using gonadotropin-releasing hormone antagonist (GnRH-ant) and gonadotropin-releasing hormone agonist (GnRH-a), as well as the risk factors for premature spontaneous ovulation. Methods The rates of premature spontaneous ovulation in a total of 10 612 cycles using GnRH-ant or GnRH-a were compared. Matched case-controlled study and binary logistic regression model were conducted to analyze the risk factors for premature spontaneous ovulation. Results The spontaneous ovulation rate in the whole for GnRH-a cycles was 0.15%(13/8 514), compared with a 1.62%(34/2 098) in GnRH-ant cycles (P<0.01). Further matched controlled study and regression analyze found out that higher basal FSH level was a predominant risk and prediction factor for spontaneous ovulation (OR=1.20, P=0.009). Conclusions In GnRH-ant cycles, spontaneous ovulation rate is about 10 times than which in GnRH-a cycles. Diminished ovarian function is a predominate risk factor for premature spontaneous ovulation.
