: Polycystic ovary syndrome (PCOS) is a common endocrine disorder associated with various cardiometabolic risk factors, including insulin resistance, dyslipidemia, hypertension, and obesity, which contribute to an increased risk of cardiovascular diseases. This inaugural systematic review and meta-analysis of randomized controlled trials (RCTs) evaluated the impact of magnesium supplementation on various cardiometabolic risk factors and hormonal parameters in patients with polycystic ovary syndrome (PCOS). : We systematically searched the MEDLINE, Web of Science, Scopus, and Cochrane databases until 30 March 2024 for studies comparing magnesium supplementation to control in improving cardiometabolic and hormonal factors in PCOS patients. Endpoints were summarized as mean differences (MD) and 95% confidence intervals (CIs) in a random-effects model. : The primary search yielded 176 studies. After screening, six studies met our inclusion criteria. Our meta-analysis showed no significant effects of magnesium supplementation on cardiometabolic risk factors and hormonal parameters in patients with PCOS. : Magnesium supplementation does not appear to influence the cardiometabolic and hormonal factors in PCOS patients. Further rigorous RCTs are needed to strengthen the evidence and support comprehensive analysis in this area. PROSPERO database (CRD42024526110).

Background: Visceral fat accumulation and dyslipidaemia are associated with infertility symptoms. The cardiometabolic index (CMI) is a comprehensive quantitative measure of central obesity and dyslipidaemia. However, the link between the female CMI and the couple infertility needs to be explored further.

Background: Although existing studies have reported associations between blood group A and cardiometabolic diseases (CMD), most have focused on dominant inheritance models. However, genome-wide association studies have mostly been based on additive genotypes. This study aims to investigate the association between the blood group A allele and 15 CMD using recessive, dominant, and additive models and identify potential mediators.

Evidence on when socioeconomic inequalities in conventional cardiometabolic risk factors emerge and how these change over time is sparse but important in identifying pathways to socioeconomic inequalities in cardiovascular disease (CVD). We examine socioeconomic inequalities in cardiometabolic risk factors trajectories across childhood and adolescence. Data were from the Avon Longitudinal Study of Parents and Children (ALSPAC), born in 1991/1992.

Objective: Law enforcement officers (LEOs) face numerous stressors that exacerbate cardiometabolic disease (CMD) risk. The current study examined novel and classic risk factors among a cohort of LEOs to better understand relationships between biomarkers of stress, oxidative stress, inflammation, and CMD risk.

Methods: Associations between measures of cardiorespiratory and muscular fitness, body composition, and cardiometabolic health with novel/classic CMD risk factors were assessed among 66 male LEOs.
