Abstract | Context: Physical activity (PA) is associated with 25-hydroxyvitamin D [25(OH)D] levels. Both are associated with atherosclerotic cardiovascular disease (ASCVD), but their joint association with ASCVD risk is unknown. Objective: To examine the relationship between PA and 25(OH)D, and assess effect modification of 25(OH)D and PA with ASCVD. Design: Cross-sectional and prospective study. Setting: […]

Abstract | Context: Evidence supports a protective effect of menopausal hormone therapy (HT) on bone. However, whether genetic susceptibility modifies the association of HT and fracture risk is not sufficiently explored. Objective: The objective was to test an interaction between genetic susceptibility and HT on fracture risk. Design: We constructed two weighted genetic risk scores […]

ABSTRACT | Objective: To explore the association between postmenopausal hormone therapy (HT) and Alzheimer disease (AD). Methods: Twenty-year follow-up data from the Kuopio Osteoporosis Risk Factor and Prevention study cohort were used. Self-administered questionnaires were sent to all women aged 47–56 years, residing in Kuopio Province starting in 1989 until 2009, every 5th year. Register-based […]

Abstract: The Mediterranean Diet (MD) has been associated with reduced mortality and risk of cardiovascular diseases, but there is only limited evidence on cancer. We investigated the relationship between adherence to MD and risk of postmenopausal breast cancer (and estrogen/progesterone receptor subtypes, ER/PR). In the Netherlands Cohort Study, 62,573 women aged 55–69 years provided information […]

Controversy exists regarding the safety of testosterone replacement therapy (TRT) following recent reports of an increased risk of adverse cardiovascular events. To investigate the association between TRT and cardiovascular outcomes in men with androgen deficiency. A retrospective cohort study was conducted within an integrated health care delivery system. Men at least 40 years old with […]

Abstract | Introduction: The female sexual response is complex and influenced by several biological, psychological, and social factors. Testosterone is believed to modulate a woman’s sexual response and desire, because low levels are considered a risk factor for impaired sexual function, but previous studies have been inconclusive. Aim: To investigate how androgen levels and psychosocial […]

Abstract | Context: Findings of studies of testosterone’s effects on muscle strength and physical function in older men have been inconsistent; its effects on muscle power and fatigability have not been studied. Objective: To determine the effects of testosterone administration for 3 years in older men on muscle strength, power, fatigability, and physical function. Design, […]

Abstract | Context: Common concerns when using low-calorie diets as a treatment for obesity are the reduction in fat-free mass, mostly muscular mass, that occurs together with the fat mass (FM) loss, and determining the best methodologies to evaluate body composition changes. Objective: This study aimed to evaluate the very-low-calorie ketogenic (VLCK) diet-induced changes in […]

Abstract | Context: Endothelial microRNA 126 (miR-126) attenuates the development of atherosclerosis (AS). However, there is no evidence showing the role of miR-126 in estrogen’s antiatherogenic effects. Objective: We hypothesized that 17β-estradiol (E2) modulates miR-126 expression and thus may improve endothelial function and retard AS development. Design/Setting/Participants: This was a prospective cohort study of 12 […]
