Background: Gestational Diabetes Mellitus (GDM) is the most common metabolic complications of pregnancy, and causes fetal mortality and morbidity. Therefore, early diagnosis of GDM is necessary to reduce maternal and fetal morbidity and to help prevent or delay the onset of type 2 diabetesObjective: This prospective study was carried out to determine the incidence of GDM in Yazd and to assess the effect of various contributing factors.Materials and Methods: One thousand and seventy one pregnant women were screened for GDM at 24-28 weeks. Initial screening was done by a glucose challenge test with 50 g glucose. If the 1-hour blood glucose level exceeded 130 mg/dl, then a 3-hour oral glucose tolerance test (OGTT) with 100g glucose was performed and diagnosis was established according to American Diabetes Association criteria.Results: Three hundred and forty two (31.9%) women had an abnormal screening test and proceeded to oral glucose tolerance testing. The overall incidence of GDM was 10.2% (n=110). Seventy six of subjects (7.1%) have one abnormal OGTT. There was a significant association between incidence of GDM and age, familial history of diabetes, BMI before pregnancy, parity, history of GDM, macrosomic baby, still birth during previous pregnancies and systolic and diastolic blood pressure. Conclusion: According to high incidence of GDM in our area we recommend screening for GDM in all pregnant women and modification of contributing factors in high risk women.

    • "A study from Iran determined that the incidence of GDM increased in women who had a previous abortion, stillbirth, history of macrosomia, and a previous history of GDM. Pre-pregnancy BMI was considered a predictor development of GDM (Soheilykhah et al., 2010). A limitation of our study is that T2DM women before pregnancy were not included as a study group in our GDM study. "

    ABSTRACT: Background Type 2 Diabetes Mellitus (T2DM) and Gestational Diabetes Mellitus (GDM) are part of a heterogeneous and complex metabolic group of disorders that share common pathophysiological circumstances, including β-cell dysfunction and insulin resistance. The protein Calpain 10 (CAPN10) plays a role in glucose metabolism, pancreatic β-cell insulin secretion, and thermogenesis. Objective Polymerase Chain Reaction–Restriction Fragment Length Polymorphism (PCR–RFLP) based genotyping of CAPN10 (rs2975760) polymorphism was carried out in T2DM and GDM with suitable controls for each of the pathologies from the same population. Genomic DNA was isolated from 787 participants, including 250 cases of T2DM, 287 pregnant women, of which 137 were identified as having GDM and the remaining 150 were confirmed as non-GDM, and 250 healthy control volunteers, and association analysis was carried out for genotypes and alleles. Results In the present study, T2DM was compared with healthy controls and was not found to be associated with the CAPN10 C allele (odds ratio, OR: 1.09; 95% CI = 0.8011–1.484; p = 0.5821). GDM also did not show any association when compared with non-GDM (OR: 1.124; 95% CI = 0.7585–1.667; p = 0.5606) respectively. Conclusion Our study suggests that the CAPN10 (rs2975760) polymorphism scrutinized in this study is not associated with T2DM and GDM.

    ABSTRACT: Background and Objectives: Gestational diabetes mellitus (GDM) is a global health concern as it affects health status of both mother and fetus. In India, prevalence of GDM varies in different populations and no data is available from rural Haryana. This study was undertaken to determine the prevalence of GDM and risk factors associated with it in rural women of Haryana. Materials and Methods: Nine hundred and thirteen women, with estimated gestational age above 24 weeks from a rural block of Haryana who consented to participate were given a standardized 2-h 75-g oral glucose tolerance test (OGTT). Pro forma containing general information on demographic characteristics, educational level, gravida, family history of diabetes, and past history of GDM was filled-up. A World Health Organization (WHO) criterion for 2-h 75-g OGTT was used for diagnosing GDM. Results: GDM was diagnosed in 127/913 (13.9%) women with higher mean age as compared to non-GDM women. Majority (78.4%) of the women were housewives, rest engaged in agriculture (9.2%) and labor (5.5%). Women with gravida ≥3 and positive family history of diabetes had significantly higher prevalence of GDM. History of macrosomia (birth weight ≥4 kg) was significantly associated with prevalence of GDM (P = 0.002). On multiple logistic regression analysis, risk factors found to be significantly associated with GDM were maternal age >25 years, gravida >3, history of macrosomic baby, and family history of diabetes. Conclusion: The prevalence of GDM has been found quite high in rural Haryana. Appropriate interventions are required for control and risk factor modifications.

    ABSTRACT: (1) To assess the prevalence of osteoporosis risk factors in Spanish menopausal women; (2) to detect medical and lifestyle risk factor differences between perimenopausal and postmenopausal women; (3) and to identify the main factors responsible for osteoporosis. Cross-sectional descriptive study encompassing women aged 45-65 across Spain. The study population sample was collected through random sampling and a total of 10,514 women were included. Socio-demographic, medical history, and lifestyle data were assessed. The prevalence of osteoporosis risk factors was 67.6%. The most common risk factors were physical inactivity (53.6%), use of medication related to osteoporosis risk (45.9%), and low calcium intake (30.1%). There were statistically significant differences between peri- and postmenopausal women in terms of smoking status, alcohol intake, personal history, poor dairy product intake, and medication use that could increase risk. Logistic regression analysis showed that osteoporosis was significantly associated with age, family history, age at onset of menopause, Kupperman Index, prolonged immobilization, weight loss, and other diseases that increase the probability of developing osteoporosis. A high prevalence of women taking osteoporosis risk-related medication was observed in our study. There was correlation between the menopausal symptoms' degree of severity and the risk of suffering from osteoporosis.
