Sex disparities in gallstone disease: insights from the MAUCO prospective population-based cohort study.

Objective: To investigate factors associated with the prevalence and incidence of gallstone disease (GSD) in women and men of the MAUCO population-based prospective cohort.

Design: 8948 MAUCO participants (aged 38-74 years) underwent abdominal ultrasound at baseline (2015-2019); 4385 received follow-up ultrasound at years 2 or 4. Factors associated with prevalent GSD were assessed using Poisson multiple regression and with incident GSD using Cox regression models.

Chronic pain in Chile: first prevalence report of noncancer chronic pain, fibromyalgia, and neuropathic pain and its associated factors.

Although we know chronic pain (CP) affects approximately 30% of people in developed countries, data from Latin America are scarce.
