Until now, herpes zoster (HZ)-related disease burden in Germany has been estimated based on health insurance data and clinical findings. However, the validity of self-reported HZ is unclear. This study investigated the validity of self-reported herpes zoster (HZ) and its complication postherpetic neuralgia (PHN) using data from the pretest studies of the German National Cohort (GNC) in comparison with estimates based on health insurance data. Data of 4751 participants aged between 20 and 69 year...

Abstract Objectives To assess the relationship between muscular strength measures and mortality in outpatient populations with chronic diseases such as cancer, chronic obstructive pulmonary disease, renal disease, and metabolic and vascular diseases, and in critically ill hospitalized patients. Design A systematic review and random-effects meta-analysis of prospective cohort studies was performed. Setting and participants The databases Medline, Embase, Clinical Trial Register, and Cochrane Trial...

Importance: The causality of the association between physical activity and risk of breast and endometrial cancers is uncertain because available evidence is based exclusively on observational studies, which are potentially susceptible to confounding and reverse causation. Objective: To investigate whether increased physical activity is causally associated with decreased risk of breast and endometrial cancers, using a two-sample Mendelian randomization study design. Design, Setting, and Participa...

Gallstones, a common gastrointestinal condition, can lead to several digestive complications and can result in inflammation. Risk factors for gallstones include obesity, diabetes, smoking and physical inactivity, all of which are known risk factors for colorectal cancer (CRC), as is inflammation. However, it is unclear whether gallstones are a risk factor for CRC. We examined the association between history of gallstones and CRC in the European Prospective Investigation into Cancer and Nutrition...

Purpose of Review Sedentary behavior is an emerging risk factor for several cancers. Here, we review the current epidemiologic evidence on sedentary behavior and cancer risk and summarize potential underlying molecular mechanisms.

Background The last few years have seen renewed interest in use-of-time recalls in epidemiological studies, driven by a focus on the 24-h day [including sleep, sitting, and light physical activity (LPA)] rather than just moderate-vigorous physical activity (MVPA). This paper describes four different computerised use-of-time instruments (ACT24, PAR, MARCA and cpar24) and presents population time-use data from a collective sample of 8286 adults from different population studies conducted in Austra...

Background & Aims To date, evidence on the association between physical activity and risk of hepatobiliary cancers has been inconclusive. We examined this association in the European Prospective Investigation into Cancer and Nutrition cohort (EPIC). Methods We identified 275 hepatocellular carcinoma (HCC) cases, 93 intrahepatic bile duct cancers (IHBCs), and 164 non-gallbladder extrahepatic bile duct cancers (NGBCs) among 467,336 EPIC participants (median follow-up 14.9 years). We estimated caus...
