Prospective association of low total testosterone levels with adverse lipid profile and incident dyslipidemia: results from the study of health in Pomerania

Haring Robin , Baumeister Sebastian , Volzke Henry , Dorr Marcus , Felix Stephan , Kroemer Heyo , Nauck Matthias , Wallaschofski Henri

Context: Previous studies suggest that total testosterone levels influences lipid metabolism. It has not been investigated whether these levels are prospectively associated with an unfavourable lipid profile including increased risk of incident dyslipidemia.Design and setting: We used data of 1468 men aged 20–79 years, repeatedly examined in the population-based Study of Health in Pomerania. Serum total testosterone levels, measured by chemiluminesc...

Mendelian randomization suggests non-causal associations of testosterone with cardiometabolic risk factors and mortality

Haring Robin , Teumer Alexander , Volker Uwe , Dorr Marcus , Nauck Matthias , Biffar Reiner , Volzke Henry , Baumeister Sebastian , Wallaschofski Henri

Background: Prospective studies showed that low serum testosterone concentrations are associated with various cardiometabolic risk factors and mortality. But the causal nature of these associations is controversial.Methods: We studied 1882 men aged 20–79 years with serum testosterone concentrations and genotyping data from the longitudinal population-based Study of Health in Pomerania.Testosterone concentrations were cross-sec...

Prediction of metabolic syndrome by low serum testosterone levels in men: results from the Study of Health in Pomerania

Haring Robin , Volzke Henry , Felix Stephan B , Schipf Sabine , Dorr Marcus , Rosskopf Dieter , Nauck Matthias , Schofl Christof , Wallaschofski Henri

Aim: The aim of this analysis was to determine whether low serum testosterone (T) and dehydroepiandrosterone sulfate (DHEAS) levels predict the development of metabolic syndrome (MetS) in men.Methods: Data were obtained from the Study of Health in Pomerania (SHIP), a population-based prospective cohort of adults aged 20–79 at baseline. Analyses were conducted in 1004 men without baseline MetS, defined by National Cholesterol Education Program Adult ...

Is response bias in population studies on iodine supply and thyroid disorders neglectable?

Volzke Henry , Haring Robin , Schmidt Carsten O , Alte Dietrich , Kramer Axel , Hoffmann Wolfgang , John Ulrich , Wallaschofski Henri

Context: Monitoring of iodine fortification programs is required for early recognition of oversupply or ineffective supply with iodine. Potential effects of non-response studies that are aimed at monitoring such programs have not been analysed.Objective: With the present analyses we investigated the potential role of selection bias for studies performed to monitor the iodine supply and prevalence of thyroid disorders.Design: The pr...

Introduction: To date, associations between sex hormones and sleep were mainly investigated in small and selected patient-based samples. Thus, we examined a comprehensive panel of mass spectrometry-measured sex hormones and various sleep characteristics in a population-based sample of healthy men and women from the general population.Methods: We used data from 204 men and 213 women of the cross-sectional Study of Health in Pomerania TREND, who underwent ...
