Objective: We prospectively evaluated how well combinations of signs and symptoms can identify individuals in the prodromal phase of Parkinson's disease (PD).

Methods: The study comprised 6,108 men who underwent repeated assessments of key prodromal features and were prospectively followed for the development of PD. Two composite measures of prodromal PD were evaluated: (i) the co-occurrence of constipation, probable rapid eye movement (REM) sleep behavior disorder (pRBD), and hyposmia, and (ii) the probability of prodromal PD based on the Movement Disorders Society (MDS) research criteria.

To determine subclinical cardiovascular disease (sCVD) in middle-aged women with clinically manifested hand osteoarthritis (HOA) and to improve the characterization of cardiovascular risk in this population. We cross-sectionally evaluated the relationship between HOA and sCVD in 1,803 volunteers from the Mexican Teachers' Cohort. From 2012 to 2016, a subsample from Mexico City, the Northern state Nuevo León, and the Southern states Chiapas and Yucatán was invited for clinical evaluations, during which neurologists examined carotid arteries using ultrasound, and a standardized HOA questionnaire was also administered.

Background: Flavonoids have been proposed to reduce the risk of Parkinson's disease (PD). However, results from epidemiological studies have been inconclusive.

Objective: To prospectively examine the association between the intake of flavonoids and their subclasses and the risk of PD and how pesticides may confound or modify that association.

Background: A shared biological component between melanoma and Parkinson's disease (PD) has been suggested. Yet, epidemiological evidence is scarce.

Objective: To examine the association of hair color and family history of melanoma, two strong predictors of melanoma risk, with the occurrence of PD.

Background: Cognitive deficits can be present in the prodromal phase of Parkinson's disease (PD). Subjective cognitive decline (SCD) may contribute to identifying individuals with prodromal PD.

Objective: The objective of this study was to examine whether SCD is more likely to be present in women with features suggestive of prodromal PD compared with women without these features.

Hair cortisol concentration (HCC) represent a potential biomarker of chronic psychological stress. Previous studies exploring the association between perceived stress and HCC have been limited to relatively small and selected populations. We collected hair samples from 881 women from the Mexican Teachers' Cohort (MTC) and 398 women from the Icelandic SAGA pilot-cohort following identical protocols.

Background: Folate and vitamins B6 and B12 have been proposed as protective against the development of Parkinson's disease (PD). Two prior longitudinal studies were inconclusive.

Objective: The aim was to examine the association of long-term intake of folate, vitamin B6, and vitamin B12 with the incidence of PD.

To determine whether long-term sun exposure has a protective role in subclinical cardiovascular disease in adult Mexican women. We conducted a cross-sectional analysis of a sample of women from the Mexican Teachers' Cohort (MTC) study. Sun exposure was assessed in the MTC 2008 baseline questionnaire, in which women were asked about their sun-related behavior.

Objective: To examine the factor structure of the 4- and 10-item Perceived Stress Scale (PSS) among 1 310 Mexican women participating in a prospective cancer cohort study.

Materials And Methods: We performed exploratory and confirmatory factor analyses in two sub-samples of the Mexican Teachers' Cohort. We evaluated internal consistency, estimated the correlation between PSS-4 and PSS-10, and assessed their correlation with a depressive symptoms scale.

Purpose: To investigate the association between serious financial difficulties (SFD), stress, and cardiovascular health in women.

Methods: We categorized 1759 employed and insured disease-free women from the Mexican Teachers' Cohort according to their response to a question on SFD included in the Life Stressor Checklist-Revised administered in 2012 and 2016. We also measured perceived stress (n = 1598) and hair cortisol levels (n = 539) in study participants.

Women are exposed to a variety of life stressors, particularly violence, during their lifetime which increases the risk of developing various psychiatric and somatic diseases, with the dysregulated secretion of cortisol as one potential biological mechanism. We examined the association between violence and other life stressors and hair cortisol concentration (HCC) in a population of urban women. We included 470 adult women (age = 21-86 years) attending the Cancer Detection Clinic in Iceland.

Objective: Subtle cognitive deficits can occur during the prodromal phase of Parkinson's disease (PD), commonly in conjunction with hyposmia. However, little is known about the association between cognitive function and other features suggestive of prodromal PD. We evaluated the association of non-motor prodromal PD features, including hyposmia, constipation and probable REM sleep behaviour disorder (pRBD), with objective measures of cognitive function and self-reported cognitive decline.

To describe the prevalence and correlates of depressive symptoms, generalized anxiety disorder (GAD), and perceived negative mental health impact during the SARS-Cov-2 pandemic in Mexico City and evaluate their association with adherence to stay-at-home directives. Baseline data from a cohort study of 2,016 Mexico City government employees were analyzed using multivariable logistic regression models. Among participants, 17.

To examine the association between family member incarceration, psychological stress, and subclinical cardiovascular disease (CVD). Between 2012 and 2016, 1849 CVD-free women from the Mexican Teachers' Cohort responded to questions on family incarceration from the Life Stressor Checklist. Perceived stress and hair cortisol levels were measured in a subset of participants.

Background: Childhood adversities are prevalent worldwide and might affect adult cardiovascular health. However, in middle-income countries such as Mexico, research on the impact of childhood adversities on cardiovascular disease (CVD) in adulthood is lacking.

Objective: To evaluate the prevalence of adverse childhood experiences (ACEs) and their association with risk factors for CVD in adult Mexican women.

Background: Violence against women has become a global public health threat. Data on the potential impact of exposure to violence on cardiovascular disease are scarce.

Methods And Results: We evaluated the association between exposure to violence and subclinical cardiovascular disease in 634 disease-free women from the Mexican Teachers' Cohort who responded to violence-related items from the Life Stressor Checklist and underwent measures of carotid artery intima-media thickness in 2012 and 2013.
