Inflammatory Index

ObjectivesThis study aimed to assess the relationship between dietary inflammatory index (DII) and sex steroids in children (6-11 years old) and adolescents (12-19 years old) in the U.S. National Health and Nutrition Examination Survey, 2015–2016.MethodsParticipants between the ages of 6-19 have 24-hour dietary intake data, serum sex hormones [total testosterone (TT), estradiol (E2)], and sex hormone-binding globulin (SHBG) available data (n = 1382). The free androgen index (FAI) is calculated as TT divided by SHBG and the ratio of TT to E2 (TT/E2). The constructed puberty state is defined as high levels of steroid hormones (TT≥50 ng/dL in men, E2≥20 pg/ml in women) or onset of menarche. Multiple linear regression analysis was stratified by gender-age and gender-pubertal status groups to evaluate the association between DII and sex hormone levels.ResultsAfter adjusting for covariates, the association between consecutive DII and sex hormone indicators by gender and age group. In male adolescents, DII was always negatively associated with TT (P-trend = 0.09), FAI (P-trend = 0.03) and E2 (P-trend = 0.01), and monotonically positively associated with SHBG (P-trend = 0.02).In female adolescents, with the increase of DII, a significant positive correlation with SHBG was observed (β 0.017, 95%CI: 0.009,0.053) (Table 3). Among female adolescents, a significant negative association between DII and TT and a significant positive association between SHBG were observed in this group. Moreover, DII was positively associated with SHBG of prepubertal males and negatively associated with FAI of prepubertal females.ConclusionsDII was associated with decreased levels of certain sex steroid hormones (TT, FAI, and E2) and increased levels of SHBG in adolescents or pubertal individuals, with the associations presenting somewhat sex-dependent pattern. However, there is little evidence that there is a significant association in children or prepubertal children. Further research needs to be carried out to verify our results.

AimsDiet has been found to have an important effect on sex hormones. The effect of diet-induced inflammation on sex hormones has not been studied in detail among women. Therefore, we aimed to investigate the association between energy-adjusted dietary inflammatory index (E-DII) and sex hormones among postmenopausal women.MethodsThis study used data from the National Health and Nutrition Examination Survey (NHANES) 2013–2016 waves. A total of 1183 postmenopausal women who provided information on two 24-hour dietary intake recalls, sex hormones including total testosterone (TT), estradiol (E2), TT/E2, sex hormone-binding globulin (SHBG), free estradiol (FE2) and free testosterone (FT), as well as selected covariates were included. Linear regression and restricted cubic spline evaluated the association between E-DII and sex hormones. Effect modification by body mass index (BMI) and type of menopause was then examined in stratified analysis.ResultsAfter adjusting for covariates, linear regression showed that E-DII was positively associated with TT (P=0.035), FT (P=0.026) and TT/E2 (P=0.065). TT (P-nonlinear = 0.037) and TT/E2 (P-nonlinear = 0.035) had significant nonlinear association with E-DII. E2 (P-nonlinear = 0.046) and FE2 (P-nonlinear = 0.027) depicted a nonlinear U-shaped significant association with E-DII, the two inflection points were found at the E-DII score of -0.22 and 0.07, respectively, the associations in natural menopausal women were more pronounced.ConclusionsOur study indicates that several indicators of androgen and estrogen were associated with E-DII in postmenopausal women. Further research is needed to understand the underlying mechanisms.

Objective: To investigate whether circulating levels of testosterone (total, bioavailable), estradiol (total, bioavailable), and DHEA sulfate (DHEAS) are associated with fasting plasma homocysteine (tHcy) levels in middle-aged and elderly men. Design: A population-based sample of 400 independently living men between 40 and 80 years of age in a cross-sectional study. Methods: Total testosterone, sex hormone binding globulin (SHBG), and total estradiol were measured by RIA methods and bioavailable testosterone and estradiol were calculated. DHEAS was measured using an immunometric technique. Fasting homocysteine was measured by fluorescence polarization immunoassay. Anthropometric characteristics were also measured and two standardized questionnaires completed, including life-style factors and diet. Linear regression analysis adjusted for age, body mass index (BMI), creatinine clearance, and mean visceral fat was used to assess the association of endogenous sex hormones and fasting plasma homocysteine levels. Results: After adjustment for age, BMI, creatinine clearance, and mean visceral fat no statistically significant association was observed between testosterone (total, bioavailable), DHEAS, and estradiol (total, bioavailable)levels with natural log tHcy (β = −2 × 10−3; 95% confidence intervals (CI) −9 × 10−3; 5 × 10−3), (β = −4 × 10−3; 95% CI −18 × 10−3; 9 × 10−3), (β = 3 × 10−3; 95% CI −6 × 10−3; 12 × 10−3), (β = −9.3 × 10−5; 95% CI −1 × 10−3; 1 × 10−3), and (β = 0.00; 95% CI −3 × 10−3; 2 × 10−3) respectively. Additional adjustment for smoking, alcohol intake, daily physical activity, diabetes mellitus, and hypertension did not change these findings. Conclusion: The results of our study do not support a direct role for circulating sex hormone levels in the regulation of fasting plasma tHcy concentrations in middle-aged and elderly men.

Background: Sex is a major determinant of cardiovascular disease (CVD). Endogenous sex hormones exert a variety of effects on the vascular endothelium, and changes in sex hormone levels after menopause may play a role in CVD risk in women. We hypothesized that a more androgenic sex hormone profile among post-menopausal women, but not among men, would be associated with reduced blood flow-mediated vasodilation (FMD) of the brachial artery, a marker of worse endothelial function. Methods: We examined 1396 post-menopausal women and 1707 men participating in MESA, who were free of clinical CVD at baseline. Sex hormone levels [total testosterone (T), sex hormone binding globulin (SHBG), estradiol (E2)] were measured at Exam 1 (2000-02); free T and T/E2 ratio were calculated. FMD was measured by high-resolution ultrasound. Using multivariable adjusted Poisson and linear regression methods, we tested the cross-sectional associations of sex hormones (log transformed) with FMD. Results: The mean age of men and women was 61 and 64 years, respectively. Of women, 34% were using hormone therapy (HT). Among women, after adjusting for demographics, CVD risk factors, and HT use, higher SHBG was associated with higher FMD, whereas higher free T was associated with lower FMD (Table, Model 2). In women, when examining the “best FMD response” (top decile vs. bottom 9 deciles), higher E2 was positively associated with a prevalent best response, whereas higher free T was inversely associated. Among men, a higher T/E2 ratio was marginally associated with lower FMD. Conclusion: The association between sex hormones and FMD differs in men and women. Higher E2 and SHBG and lower free T levels were associated with better FMD in post-menopausal women but not in men. Higher T/E2 ratio was associated with lower FMD in men. Further studies are needed to assess longitudinal changes in sex hormone levels and their association with vascular aging. Sex hormone levels may help identify individuals at increased CVD risk who may benefit from other risk reduction strategies.

OBJECTIVE: To determine the relationship between aging, life-style factors and health-related factors and endogenous sex hormone levels. DESIGN: Cross-sectional study of 400 independently living men between 40 and 80 Years of age. METHODS: After exclusion of subjects who were not physically or mentally able to visit the study center, 400 men were randomly selected from a population-based sample. Total testosterone (TT), bioavailable testosterone (BT) (i.e. not bound to sex hormone-binding globulin (SHBG)), SHBG, estradiol (E(2)) and dehydroepiandrosterone-sulfate (DHEA-S) were investigated for their relationship with age, body mass index (BMI), waist circumference, smoking, physical activity and general health status. Multivariate models using ANCOVA analyses were used to examine the contribution of life-style factors to sex hormone variability. RESULTS: TT, BT and DHEA-S decreased with age; 0.2, 0.7 and 1.2%/Year respectively. SHBG showed an increase with age of 1.1%/Year. No changes with age were found for E(2). General health status modified the association of TT and SHBG with age (P interaction 0.10 and 0.002 respectively). Increased BMI and waist circumference were associated with decreased TT, BT, SHBG and DHEA-S and increased E(2) (all P<0.01). Current smoking, lower alcohol intake and a higher physical activity score were associated with higher TT and SHBG levels. CONCLUSION: This study showed the important determinants of sex hormones were age, BMI, waist circumference, smoking, general health status and physical activity. Furthermore, it can be concluded that general health status modified the effect between sex hormones and age. For future observational studies it should be taken into account that the above-mentioned determinants may alter the association between sex hormones and diseases and related conditions.

Abstract Background Although sex hormones play critical roles in spermatogenesis and sperm maturation, it remains inconclusive whether circulating sex hormones can serve as non-invasive biomarkers to improve the assessment of sperm quality. Methods We systematically evaluated the association of various sex hormones in serum with sperm quality among 338 men in subfertile couples. Concentrations of luteinizing hormone (LH), follicle-stimulating hormone (FSH), total testosterone (TT), total estradiol (E2), and sex hormone-binding globulin (SHBG) were detected by chemiluminescent immunoassay. Free testosterone and estradiol were calculated using a validated algorithm. A generalized liner regression model controlling for lifestyle factors was used to evaluate the associations with sperm count, concentration, motility, and morphology.Results After adjusting for age, body mass index, current smoking and alcohol drinking, LH, FSH, and TT levels were all inversely associated with sperm motility (all P for trend < 0.05); however, in mutual adjustment analysis, only LH remained an inverse association with sperm motility after adjusting for FSH and TT levels (P for trend = 0.04). Higher concentrations of LH were also associated with lower sperm progressive motility (P for trend = 0.04). Moreover, LH and FSH levels were both inversely associated with normal sperm morphology (P for trend = 0.04 and 0.02, respectively). Conclusions Increased levels of LH are associated with poor sperm motility and morphology, suggesting that LH may play a central role in sperm maturation. Future studies are warranted to assess potential clinical utility of LH for risk stratification and tailed prevention of male infertility.

Statin Use

ObjectiveStatins, or HMG-CoA reductase inhibitors, decrease cholesterol production. Because cholesterol is a precursor of the testosterone biosynthesis pathway, there is some concern that statins might lower serum testosterone levels. The objective of the present study was to investigate the association between the use of statins and serum testosterone levels in men.DesignCross-sectional study within the prospective population-based Rotterdam Study.Subjects and methodsWe included 4166 men with available data on total testosterone, non-sex hormone-binding globulin (SHBG)-bound testosterone, and medication use. Multivariable linear regression analysis was used to compare the differences in serum testosterone levels (nmol/l) between current, past, and never statin users. We considered dose and duration of use. Analyses were adjusted for age, BMI, cardiovascular disease, diabetes mellitus, hypertension, and estradiol levels.ResultsWe identified 577 current (mean age 64.1 years), 148 past (mean age 64.6 years), and 3441 never (mean age 64.6 years) statin users. Adjusted for all covariables, current statin use of 1–≤6 months or >6 months was significantly associated with lower total testosterone levels as compared to non-users (β −1.24, 95% CI −2.17, −0.31, and β −1.14, 95% CI −2.07, −0.20 respectively). Current use of 1–≤6 months was also associated with significantly lower non-SHBG-bound testosterone levels (β −0.42, 95% CI −0.82, −0.02). There was a trend toward lower testosterone levels at higher statin doses both for total (Ptrend 2.9×10−5) and non-SHBG-bound (Ptrend 2.0×10−4) testosterone. No association between past statin use and testosterone levels was found.ConclusionWe showed that current use of statins was associated with significantly lower serum total and non-SHBG-bound testosterone levels. The clinical relevance of this association should be further investigated.

Abstract Context Sex differences exist in heart failure (HF) phenotypes, but there is limited research on the role of sex hormones in HF and its subtypes. Objective To examine the associations of total testosterone, dehydroepiandrosterone sulfate (DHEA-S), and sex hormone-binding globulin (SHBG) with incident HF, HF with preserved ejection fraction (HFpEF), and HF with reduced ejection fraction (HFrEF). Design Atherosclerosis Risk in Communities (ARIC) study (prospective cohort study). Median follow-up is 19.2 years. Setting General community. Participants 4107 men and 4839 postmenopausal women, with mean age of 63.2 (standard deviation [SD] 5.7) and 62.8 (5.5) years, respectively. Exposure Plasma sex hormone levels were measured at visit 4 (1996-1998). Main Outcome Measures Incident HF events were identified through hospital discharge codes and death certificates. Results The Hazard Ratios for HF associated with 1 SD decrease in log-transformed total testosterone, DHEA-S, and SHBG were 1.10 (95% confidence interval 1.03, 1.17), 1.07 (1.00, 1.15), and 1.04 (0.96, 1.11) in men, and 1.05 (0.99, 1.13), 1.17 (1.09, 1.24), and 0.93 (0.85, 1.01) in women, respectively. The associations between sex hormones with subtypes of HF had similar patterns but were attenuated and became statistically insignificant. Conclusion In this prospective cohort, lower levels of endogenous testosterone and DHEA-S in men and DHEA-S in postmenopausal women were associated with the development of HF. Similar directions of association in both sexes and both HF subtypes suggest that sex hormones play a role in the development of HF through common pathways regardless of sex.

We aimed to evaluate the relationship between selected serum sex hormones and lipid profiles in a group of women with polycystic ovary syndrome (PCOS) dividing according to four phenotypes, value of body mass index (BMI), and presence of hyperlipidemia. The study included 606 Caucasian women. Lipids and selected hormones were estimated using commercially available procedures during hospitalization in 2017. Phenotype of PCOS, BMI value, and hyperlipidemia were significant factors that influenced androgen hormone concentrations, such as total and free testosterone and androstenedione as well as the value of free androgen index (FAI). Moreover, significant changes in concentrations of dehydroepiandrosterone sulphate and sex hormone binding globulin (SHBG) were found between those groups. Higher quartiles of triglyceride concentrations increased the odds ratio of decreased concentrations of SHBG or increased values of FAI, while an adverse relation was found in case of HDL-C. The concentration of estradiol in the blood of women with PCOS was not associated with lipid profile parameters in any investigated groups. Probably, irregularities in sex hormone concentrations during PCOS is not directly associated with lipid profile parameters but could be reflective of the concentration of SHBG or the ratio of SHBG and total testosterone and their association with lipids.

Higher concentrations of LH were also associated with lower sperm progressive motility ( P for trend = 0.04 ). Moreover, LH and FSH levels were both inversely associated with normal sperm morphology ( P for trend = 0.04 and 0.02, respectively ). Conclusions Increased levels of LH are associated with poor sperm motility and morphology. Our findings suggest that LH might play a central role in sperm maturation, which represents a potential biomarker to improve clinical evaluation of male infertility.
