Background: Observational studies have reported that total (poly)phenol intake is associated with a reduction in all-cause and cardiovascular mortality, but mainly from high-income countries, where (poly)phenol intake may differ from that of low- and middle-income countries.

Objectives: Our objective was to evaluate the association between the intake of total, all classes, and subclasses of (poly)phenols and risk of all-cause and cause-specific mortality in a Mexican cohort.

Methods: We used data from the Mexican Teachers' Cohort, which included 95,313 adult females.

Objective: To assess the effectiveness of seven Covid-19 vaccines in preventing disease progression (DP) using data from national private sector workers during the Omicron wave in Mexico from January 2 to March 5, 2022.

Materials And Methods: This study employed an administrative retrospective cohort design, analyzing DP (hospitalization or death due to respiratory disease) among workers who filed a respiratory short-term disability claim and tested positive for SARS-CoV-2. Risk ratios (RRadj) were estimated using Poisson regression models adjusted for various factors.

Objective: To estimate prostate cancer (PC) survival in Mexico and explore survival disparities according to the marginalization level of residence place.

Materials And Methods: A nationwide administrative claims database (4 110 men) whose PC treatment was financed by Seguro Popular between 2012-2016, was cross-linked to the National Mortality Registry up to December 2019. Patients were classified according to their oncological risk at diagnosis and the marginalization level of the residence municipality.

Objective: To examine the association between low-intensity smoking (10 or less cigarettes per day) and all-cause and cause-specific mortality risk among women who smoke and by age at cessation among women who previously smoked.

Methods: In this study, 104 717 female participants of the Mexican Teachers' Cohort Study were categorised according to self-reported smoking status at baseline (2006/2008) and were followed for mortality through 2019. We estimated HRs and 95% CIs for all-cause and cause-specific mortality using multivariable Cox proportional hazards regression models with age as the underlying time metric.

Background: Essential indicators of health system performance for breast cancer are lacking in Mexico. We estimated survival and clinical stage distribution for women without social insurance who were treated under a health financing scheme that covered 60% of the Mexican population.

Methods: We conducted a retrospective cohort study cross-linking reimbursement claims for 56,847 women treated for breast cancer between 2007 and 2016 to a mortality registry.

Introduction: The COVID-19 pandemic disrupted the preventive services for cervical cancer (CC) control programs in Mexico, which will result in increased mortality. This study aims to assess the impact of the pandemic on the interruption of three preventive actions in the CC prevention program in Mexico.

Methods: This study is a retrospective time series analysis based on administrative records for the uninsured population served by the Mexican Ministry of Health.

Linking records of the same person from different sources makes it possible to build administrative cohorts and perform longitudinal analyzes, as an alternative to traditional cohort studies, and have important practical implications in producing knowledge in public health. We implemented the Fellegi-Sunter probabilistic linkage method to a sample of records from the Mexican Automated System for Hospital Discharges and the Statistical and Epidemiological System for Deaths and evaluated its performance. The records in each source were randomly divided into a training sample (25%) and a validation sample (75%).

Objective: To estimate the sensitivity and specificity of two Mexican death registries for the identification of vital status using a publicly available record-linkage tool.

Materials And Methods: We selected all reported deaths (n=581) and 575 alive participants in an epidemiologic cohort with active follow-up. Individual records were cross-linked to two mortal-ity registries.

Article Synopsis
  • * Over the decade, the number of children treated doubled, but significant disparities in survival rates existed between different states, ranging from 43.7% to 74.7%.
  • * Factors such as receiving treatment at non-specialized hospitals or those without pediatric oncology specialists significantly increased the risk of mortality, highlighting areas for improvement in Mexico's healthcare system.

Aim Of The Study: To examine mortality trends in children under 15 years of age due to HIV/AIDS in Mexico and describe their differences by insurance coverage.

Methods: Time series analysis of deaths from 1990-2019 through a Bayesian poisson regression model with linear splines and knots in 1994, 1997, and 2003.

Results: Overall, we observed a reduction in the mortality rate due to HIV from 2003 onwards, except in the group of 10-14 years.

Objective: To compare cancer mortality rates in Mexico from two national death registries that independently code and attribute cause of death.

Materials And Methods: We compared 5-year age-standardized total cancer and sitespecific cancer mortality rates (2010-2014) from Mexico's official death registry with a death registry from a disease surveillance system. We obtained age-adjusted mortality rates and 95% confidence intervals using the direct method and World Population Prospects 2010 as a standard.

Objective: To assess the magnitude of the Mexican epidemic of Zika virus infection and the associated risk of microcephaly.

Methods: From the reported number of laboratory-confirmed symptomatic infections among pregnant women and the relevant birth rate, we estimated the number of symptomatic cases of infection that occurred in Mexico between 25 November 2015, when the first confirmed Mexican case was reported, and 20 August 2016. We used data from the birth certificates to compare mean monthly incidences of congenital microcephaly before (1 January 2010-30 November 2015) and after (1 December 2015-30 September 2017) the introduction of Zika virus, stratifying the data according to whether the mother's place of residence was at an altitude of at least 2200 m above sea level.

This correspondence argues and offers recommendations for how Geographic Information System (GIS) applied to maternal and newborn health data could potentially be used as part of the broader efforts for ending preventable maternal and newborn mortality. These recommendations were generated from a technical consultation on reporting and mapping maternal deaths that was held in Washington, DC from January 12 to 13, 2015 and hosted by the United States Agency for International Development's (USAID) global Maternal and Child Survival Program (MCSP). Approximately 72 participants from over 25 global health organizations, government agencies, donors, universities, and other groups participated in the meeting.

Objective: To estimate the direct costs related to hospitalizations for diabetes mellitus and its complications in the Mexican Institute of Social Security METHODS: The hospital care costs of patients with diabetes mellitus using diagnosis-related groups in the IMSS (Mexican Institute of Social Security) and the hospital discharges from the corresponding E10-E14 codes for diabetes mellitus were estimated between 2008-2013. Costs were grouped according to demographic characteristics and main condition, and were estimated in US dollars in 2013.

Results: 411,302 diabetes mellitus discharges were recorded, representing a cost of $1,563 million.
