Insulin resistance (IR) is the corner stone of metabolic obesity. This cross-sectional analytical study was aimed to find out the frequency of IR in non-diabetic adult individuals of different obesity phenotypes that would help to implement preventive measures to avoid the cardiometabolic catastrophes.MethodsTotal 955 nondiabetic adult individuals were selected and categorized into six metabolic phenotypes by metabolic syndrome criteria in each BMI group (18.5–24.9-normal weight, 25-29.9-overweight, ≥30-obese). From them, metabolically obese normal weight, metabolically obese overweight, metabolically healthy obese and metabolically unhealthy obese were selected as Obesity phenotypes (N = 616).ResultsThe frequency of IR was found to be very high (60.2%) in total nondiabetic adult obese individuals (N = 616). Highest frequency of IR was found in MUO phenotype (76.3%), lowest frequency of IR was found in MONW phenotype (37.1%) and frequency of IR in MOOW and MHO phenotypes found to be identical but significantly (p < 0.0001) less than MUO and significantly (p < 0.0001) more than MONW phenotype. Among the obesity phenotypes, females were more insulin resistant than males (67.5% vs 48.1% respectively, p < 0.05). Frequency of IR found significantly (p < 0.05) more in female than male in all obesity phenotypes except in MUO phenotype where males found to show significantly (p < 0.05) higher frequency than females. Frequency of IR was significantly higher in younger (20–39 yrs) age group than 40–60 yrs age group (63.2% vs 53.5% respectively, p < 0.05).ConclusionIR is alarmingly high (60.2%) in nondiabetic adult obese individuals. Among different obesity phenotypes, it is highest (76.3%) in MUO and lowest (37.1%) in MONW.  相似文献

Aims

This study aimed to determine the prevalence rate of metabolic syndrome and its potential risk factors, 6–12 weeks postpartum in women with GDM compared to women with normal glucose tolerance.

Methods

LAGAs is an ongoing population-based prospective cohort study that started in March 2015 in Ahvaz, Iran. During 11 months of study progression, 176 women with GDM pregnancy and 86 healthy women underwent a fasting glucose test, 75-g OGTT and fasting lipid tests at 6–12 weeks postpartum. GDM was defined based on IADPSG criteria. Postpartum glucose intolerance was defined according to ADA criteria and metabolic syndrome using 2 sets of criteria.

Results

The overall rate of metabolic syndrome at 6–12 weeks postpartum was 16% by NCEP-ATP III criteria (18.2% in women with GDM and 11.6% in controls) and 19.1% by IDF criteria (21% in women with gestational diabetes and 15.1% in controls). Pre-pregnancy overweight or obesity, (OR 1.89, 95% CI: 1.05-3.38, P?=?.03), pregnancy systolic blood pressure (OR 1.03, 95% CI: 1.008–1.52, P?=?.006) and requiring insulin or metformin (OR 3.08, 95% CI: 1.25–7.60, P?=?0.01), were associated risk factors for the presence of MetS in GDM-exposed women. In women with normal glucose during pregnancy, pre-pregnancy BMI ≥25?kg/m2 was a risk factor of metabolic syndrome (OR 2.82, 95% CI: 1.11–7.15, P?=?.02).

Conclusion

The rate of metabolic syndrome in women with or without GDM at 6–12 weeks postpartum is high particularly in women with high BMI. An early postpartum prevention and screening program for cardiovascular risk factors is important for women with GDM.  相似文献

Background

Polycystic ovarian syndrome (PCOS) is the commonest reproductive disorder in women and is closely associated with the development of metabolic syndrome (MetS). The objective of this systematic review and meta-analysis was to describe the risk of MetS in adolescent with PCOS to help diagnosing and preventing of morbidity and mortality later in life.

Methods

Pubmed, Medline, EMBASE, CINAHL and other sources were searched for metabolic syndrome in adolescents with polycystic ovarian syndrome using PRISMA guidelines (Moher et al., 2009). All type of study design of women aged 10–20 reported association of PCOS with metabolic syndrome was included in this study. Meta-analysis was conducted for MetS and its individual component using bias adjusted quality effect model and we compare the results from quality effects with random effects and IVhet model. Data were presented as prevalence, odds ratio (95% confidence interval and mean difference (95% confidence interval).

Results

This systematic review included 9 studies while the meta-analysis included 7 studies. Meta-analysis showed that the odds of being experiencing MetS in PCOS groups was 2.69 (1.29, 5.60) times than girls without PCOS. The mean difference between girls with PCOS and without PCOS for systolic blood pressure was 5.00 (1.28, 8.72), diastolic blood pressure was 3.50 (0.48, 6.56), triglycerides level was 4.20 (?3.99, 12.45), glucose level was 1.30 (?0.46, 3.05), HDL level was ?1.40 (?4.85, 2.00).

Conclusion

This systematic review and meta-analysis support the hypothesis that the risk of MetS is much greater in adolescents with PCOS compared to the normal population. It is important to screen PCOS in early age to prevent MetS and its complications which lead to morbidity and mortality later in life.  相似文献
