Effect of high-intensity interval training on metabolic parameters in women with polycystic ovary syndrome: A systematic review and meta-analysis of randomized controlled trials.

Background: Our aim was to assess the effect of high-intensity interval training (HIIT) on metabolic parameters and body composition in women with polycystic ovary syndrome (PCOS).

Methods And Analysis: A systematic review and meta-analysis of randomized controlled trials was conducted using Embase, MEDLINE (via Ovid), PubMed, Sport Discus, Scopus, Web of Science, Cochrane Library and Google Scholar (advanced feature) up to September 2020. Two authors independently screened citations and determined the risk of bias and quality of evidence using the Grading of Recommendations Assessment, Development and Evaluation (GRADE).

The effect of exercise as an intervention for women with polycystic ovary syndrome: A systematic review and meta-analysis.

Background: Polycystic ovary syndrome (PCOS) affects reproductive-aged women and is associated with increased prevalence of serious clinical problems including: reproductive implications, metabolic dysfunction, and cardiovascular risk. Physical activity offers several health benefits for women with PCOS. The aim of this systematic review was to synthesize evidence on the effect of different types of exercise on reproductive function and body composition for women with PCOS.

Lifestyle interventions and quality of life for women with polycystic ovary syndrome: A systematic review and meta-analysis protocol.

Background: Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders in women of reproductive age. PCOS has a significant negative impact on the health-related quality of life (HRQoL) and psychological function of women, of which there are reports of high levels of depression in women with PCOS compared to those without PCOS. However, the evidence surrounding the effects of exercise and/or dietary intervention participation on the HRQoL of women with PCOS is limited.

Exercise and reproductive function in polycystic ovary syndrome: protocol of a systematic review.

Background: Although many post-participation outcomes in different types of physical training (e.g., aerobic and strength) have been previously investigated for the treatment of polycystic ovary syndrome, there is no recent systematic review of the relationship between various types of intervention and the reproductive function of women with PCOS.

The effects of 2 mg chlormadinone acetate/30 mcg ethinylestradiol, alone or combined with spironolactone, on cardiovascular risk markers in women with polycystic ovary syndrome.

Background: Polycystic ovary syndrome (PCOS) is an endocrine disorder associated with metabolic dysfunction and changes in cardiovascular risk markers, and using oral contraceptives (OCs) may exert a further negative effect on these alterations in patients with PCOS. Thus, the primary objective of this study was to assess the effects on arterial function and structure of an OC containing chlormadinone acetate (2 mg) and ethinylestradiol (30 mcg), alone or combined with spironolactone (OC+SPL), in patients with PCOS.

Study Design: This was a randomized, controlled clinical trial.

[Obesity and altered arterial structure in young women with micropolycystic ovary syndrome].

Purpose: to compare echographical cardiovascular risk factors between obese and non-obese patients with micropolycystic ovarian syndrome (MPOS).

Methods: in this transversal study, 30 obese (Body Mass Index, BMI>30 kg/m(2)) and 60 non-obese (BMI<30 kg/m(2)) MPOS patients, aging between 18 and 35 years old, were included. The following variables were measured: flow-mediated dilatation (FMD) of the brachial artery, thickness of the intima-media of the carotid artery (IMT), anthropometric data, systolic arterial pressure (SAP) and diastolic arterial pressure (DAP).

[Cardiovascular risk markers in polycystic ovary syndrome in women with and without insulin resistance].

Purpose: to evaluate whether the presence of insulin resistance (IR) alters cardiovascular risk factors in women with polycystic ovary syndrome (POS).

Methods: transversal study where 60 POS women with ages from 18 to 35 years old, with no hormone intake, were evaluated. IR was assessed through the quantitative insulin sensitivity check index (QUICKI) and defined as QUICKI <0.

Increased arterial stiffness in nonobese women with polycystic ovary syndrome (PCOS) without comorbidities: one more characteristic inherent to the syndrome?

Background: Polycystic ovary syndrome (PCOS) is associated with adverse metabolic effects. Some cardiovascular disease (CVD) risk markers are increased in women with PCOS. However, early markers of atherosclerosis are also associated with obesity and insulin resistance, which are related to PCOS.

Both a combined oral contraceptive and depot medroxyprogesterone acetate impair endothelial function in young women.

Background: The study was conducted to determine whether the use of a combined oral contraceptive (COC) or depot medroxyprogesterone acetate (DMPA) interferes with endothelial function.

Study Design: The study was conducted on 100 women between the ages of 18 and 30 years. Fifty women had not used hormonal contraception (control group) for at least 12 months, 25 were current users of a COC (ethinylestradiol 30 mcg+levonorgestrel 150 mcg) and 25 were current users of DMPA (150 mg) for at least a 6-month period.
