Gender and Age Impact on the Association Between Thyroid-Stimulating Hormone and Serum Lipids

The relationship between thyroid-stimulating hormone (TSH) and hyperlipidemia is still a topic of debate. We aimed to explore the impact of gender and age on the association between serum TSH and lipid profile in a large cohort of Chinese.This cross-sectional study enrolled 13,915 participants (8565 male, 5350 female), who self-reported as healthy without any known previous diseases. Clinical data including anthropometric measurements, thyroid function, and other serum parameters were collected. The associations between TSH and hyperlipidemia of males and females were analyzed separately after dividing TSH and age into subgroups. Odds ratio for hyperlipidemia was calculated by binary logistic regression models.Young males had significantly higher prevalence of hypercholesterolemia, hypertriglyceridemia, and high serum low-density lipoprotein-cholesterol than females, yet after menopause, females had higher prevalence than males. TSH was positively associated with hyperlipidemia independent of thyroid hormones. Males showed more reduced risks of hyperlipidemia in low TSH concentrations, while females demonstrated more enhanced risks of hyperlipidemia in high TSH concentrations. For instance, if TSH was lower than 0.3 μIU/mL, the risks of developing hypercholesterolemia and hypertriglyceridemia in males were only 0.198 (P < 0.01) and 0.425 (P < 0.05) of the reference TSH risks (between 2.0 and 3.0 μIU/mL), while in females the risks were 0.553 (P < 0.05) and 0.642 (P > 0.05), respectively. If TSH was higher than 4.0 μIU/mL, women displayed significantly higher risks of developing hypertriglyceridemia than the reference TSH risks (P < 0.05), yet, men did not demonstrate such significances.Our results showed thyroid hormone independent positive associations between serum TSH and lipids, which were substantially influenced by gender and age. Males demonstrated more protective effects of low TSH against hyperlipidemia, while females showed more detrimental effects of high TSH on hyperlipidemia.

Association Between Metabolic Syndrome and Its Individual Components With Viral Hepatitis B

BackgroundThe association between hepatitis B and metabolic syndrome (MetS) has not been well described. Overall epidemiologic evidences for this association have suggested conflicting results. The aim this study was to determine the association between hepatitis B infection and MetS using large U.S. population database, the Third National Health and Nutrition Examination Survey.MethodsIndividuals aged ≥ 18 years were included in this study. MetS was defined according to the Third Report of the National Cholesterol Education Program Adult Treatment Panel guideline. The chronic hepatitis B was defined as the presence of hepatitis B surface antigen. The presence of hepatitis B core antibody with/without surface antibody, in the absence of surface antigen, was considered as past exposure to hepatitis B. To represent national estimates, weighted frequencies for chronic hepatitis B and past exposure to hepatitis B are reported. Multivariate logistic regression analysis accounting for age, gender, race, smoking and alcohol status was conducted to identify the independent predictor(s) of MetS.ResultsThis study cohort consisted of total population of 593,594 with chronic hepatitis B and 7,280,620 with past exposure to hepatitis B. Prevalence of MetS among included study cohort was 25.7%. Inverse association was observed between MetS and chronic hepatitis B (adjusted odds ratio, 0.32; 95% confidence interval, 0.12–0.84). Among individual components of MetS, waist circumference was inversely associated with chronic hepatitis B (adjusted odds ratio, 0.31; 95% confidence interval, 0.14–0.71). No significant association was noted between past exposure to hepatitis B and MetS or its individual components.Conclusionsin this study, the authors noted significant inverse association between MetS and chronic hepatitis B.

Association Between Metabolic Syndrome and Microvascular and Macrovascular Disease in Type 2 Diabetic Mellitus

The Effect of Age on the Association Between Blood Pressure and Cognitive Function Later in Life

OBJECTIVES: To determine the prospective relationship between blood pressure (BP) and cognitive function across a wide age range.
DESIGN: Prospective population-based cohort study.
SETTING: The Rotterdam Study and the Leiden 85-plus Study.
PARTICIPANTS: Three thousand seventy-eight men and women, initial age 55 to 84 from the Rotterdam Study and 276 men and women, initial age 85, from the Leiden 85-plus Study.
MEASUREMENTS: Systolic BP (SBP) and diastolic BP (DBP) were measured at baseline, cognitive function was assessed at the end of follow-up using a dedicated neuropsychological test battery. The association between baseline BP levels and cognitive function later in life was assessed in 10-year age groups in the Rotterdam Study and in 85-year-olds of the Leiden 85-plus Study.
RESULTS: In the youngest participants (<65), SBP and DBP were not associated with cognitive function 11 years later. For persons aged 65 to 74, higher baseline SBP and DBP were related to worse cognitive function 11 years later. In contrast, in older age (≥75), higher SBP and DBP seemed to be related to better cognitive function at the end of follow-up. This effect appeared strongest in the highest age group (aged 85).
CONCLUSION: High BP was associated with greater risk of cognitive impairment in persons younger than 75 but with better cognitive function in older persons. Age-specific guidelines for BP management are needed, because the current directive that "lower is better" may not apply to BP levels in the very old.

Metabolic Syndrome and Sexual Function in Postmenopausal Women

Background

Limited literature suggests that sexual dysfunction in women covaries with the metabolic syndrome. This study examined the association of sexual function with metabolic syndrome and cardiovascular disease in healthy older women.

Methods

There were 376 postmenopausal, community-dwelling women from the Rancho Bernardo Study (mean baseline age = 73 years) that completed a clinic visit during 1999-2002 and returned the Female Sexual Function Index (FSFI) questionnaire mailed in 2002.

Results

Thirty-nine percent reported being sexually active; 41.5% met a diagnosis of metabolic syndrome. The number of metabolic syndrome components was strongly associated with decreased sexual activity, desire, and low sexual satisfaction. Waist girth, diabetes, and hypertension were associated with decreased sexual activity. Elevated triglycerides were associated with low desire. Among the cardiovascular endpoints, heart attack, coronary artery bypass, and angina were associated with decreased sexual activity, but not with sexual desire or satisfaction. Past diagnosis of heart failure, poor circulation, and stroke were not associated with sexual function. Sexually active women with metabolic syndrome met criteria for sexual dysfunction in desire, arousal, orgasm, and satisfaction domains. The FSFI Total Score did not differ significantly between sexually active and inactive women.

Conclusions

Metabolic syndrome was associated with decreased sexual activity, desire, and satisfaction in all women and with sexual dysfunction in most domains in sexually active women. Coronary artery disease was more prevalent in women with low sexual activity.     

Relationship Between the Metabolic Syndrome and BPH-Related Voiding Dysfunction

Benign prostatic hyperplasia (BPH) is a commonly occurring condition, affecting a vast number of men worldwide, and particularly in North America. Lower urinary tract symptoms (LUTS) are the bothersome consequences of bladder outlet obstruction that can result from BPH, and are likely to reduce the quality of life of individuals afflicted by this condition. The metabolic syndrome (MetS) is a condition characterized by a constellation of inter-related clinical findings that have recently increased in frequency. Recent studies have suggested that the MetS may be a contributor to BPH. Important associations between BPH and MetS include the relationship between LUTS and increased body habitus, as measured by obesity and waist circumference. Cardiovascular risk factors, which are important components of the MetS, may also be associated with BPH. The exact pathophysiology and mechanisms of these relationships however are yet to be determined. Likely contenders include a pro-inflammatory state, changes in testosterone level, and increased autonomic activity.
