Objective: The aim of this study was to analyse relationships between plasma fibroblast growth factor 21 (FGF21) levels and nutritional status, and metabolic and hormonal disturbances in polycystic ovary syndrome (PCOS) women. Design and setting: A cross-sectional study involving 85 PCOS (48 obese) and 72 non-PCOS women (41 obese) was conducted to evaluate the relationship between FGF21 levels and PCOS. Methods: Anthropometric parameters and body composition were determined. In the fasting state; serum concentrations of glucose, androgens, FSH, LH, SHBG, insulin and FGF21 were measured. Results: Plasma FGF21 levels were significantly higher in obese women compared with normal-weight women in both PCOS and non-PCOS subgroups (120.3 (18.2-698) vs 62.3 (16.4-323.6) pg/ml, P<0.05 and 87.2 (12.9-748.4) vs 62.9 (18.0-378.8) pg/ml, P<0.05 respectively). Additionally, circulating FGF21 levels were significantly higher in the obese PCOS subgroup compared with the non-PCOS subgroup (120.3 (18.2-698.0) vs 87.2 (12.9-748.4) pg/ml, P<0.05). Circulating FGF21 levels were proportional to BMI (R=0.27; P<0.001), body fat mass (R=0.24; P<0.01) and percentage (R=0.24; P<0.01), as well as waist circumference (R=0.26; P<0.01). Additionally, plasma insulin and homeostasis model assessment of insulin resistance (HOMA-IR) values were related to FGF21 levels (R=0.44; P<0.001 and R=0.19; P<0.05 respectively). In multiple regression analysis, circulating FGF21 level variability was explained by HOMA-IR values and fat percentage, as well as waist circumference, but not correlated with oestradiol levels and free androgen index values. Conclusions: Higher circulating FGF21 levels are related to nutritional status and insulin resistance independent of PCOS. Increased FGF21 is associated with metabolic but not hormonal disturbances. © 2015 European Society of Endocrinology Printed in Great Britain. Source

Objective: Hypertension and obesity deteriorate patient health-related quality-of-life (HRQoL). This study assessed the impact of overweight and obesity on HRQoL and blood pressure (BP) control in hypertensive participants, according to sex. Methods: HRQoL was assessed using the 12-item Short Form Health Survey in 11498 white patients treated for hypertension for at least 12 months. Nutritional status was diagnosed according to WHO criteria. Results: Overweight and obesity were associated with worse BP control, regardless of sex. In women, overweight and especially obesity were inversely associated with all analyzed HRQoL dimensions. Among men, obesity decreased all HRQoL dimensions, and overweight influenced only physical functioning, role physical, bodily pain, vitality, general health, and Physical Component Score (PCS) but not Mental Component Score (MCS). Overweight in men did not influence social functioning, or emotional and mental health. The BMI values associated with optimal PCS and MCS scores were higher for men than for women. Age-adjusted multivariate regression analysis revealed that PCS score was associated with obesity, higher education level, comorbidities, and antihypertensive therapy duration, whereas MCS score was associated with female sex. Polydrug BP control diminished PCS and MCS. Conclusion: Overweight and obesity deteriorate BP control, regardless of age and polytherapy. BMI values associated with optimal HRQoL are higher for men than women treated for hypertension. Obesity more strongly diminishes the physical versus mental HRQoL component, regardless of sex. Overweight worsens HRQoL physical components in both sexes and mental component-only in women. © 2014 Wolters Kluwer Health | Lippincott Williams & Wilkins. Source
