The Prevalence of Symptomatology and Risk Factors in Mental Health in Mexico: The 2016-17 ENCODAT Cohort.

There is little recent information about the prevalence of symptomatology of mental health disorders in representative population samples in Mexico. To determine the prevalence of mental health symptoms in Mexico and its comorbidity with tobacco, alcohol, and drug use disorder (SUD), we used the 2016-17 National Survey of Drug, Alcohol, and Tobacco Use (Encuesta Nacional de Consumo de Drogas, Alcohol y Tabaco, ENCODAT 2016-2017). The data were collected from households using a cross-sectional, stratified, multistage design, with a confidence level of 90% and a response rate of 73.

Changes in Attitudes toward People with Substance Use Disorder: A Comparative Study of the General Population in Mexico.

Background: Substance use disorders are among the most stigmatized conditions worldwide. People with substance use disorder (PWSUD) are often considered responsible for their use of drugs. The objectives are to analyze changes in Mexican attitudes toward PWSUD in the general population over the period 2011 to 2016 and to use the latest Mexican household survey to determine which segments of the population are most likely to have negative attitudes.

Genome-Wide Analysis of Disordered Eating Behavior in the Mexican Population.

Alterations in eating behavior characterized eating disorders (ED). The genetic factors shared between ED diagnoses have been underexplored. The present study performed a genome-wide association study in individuals with disordered eating behaviors in the Mexican population, blood methylation quantitative trait loci (blood-meQTL), summary data-based Mendelian randomization (SMR) analysis, and in silico function prediction by different algorithms.

Cannabis Use in People With Obsessive-Compulsive Symptomatology: Results From a Mexican Epidemiological Sample.

Recent studies suggest that the endocannabinoid system could play an important role in the physiopathology of obsessive-compulsive disorder (OCD). There are reports of effective treatment with derivatives of tetrahydrocannabinol (THC). The study of the genetic factor associated with psychiatric disorders has made possible an exploration of its contribution to the pharmacological response.

Genome-wide association study of psychiatric and substance use comorbidity in Mexican individuals.

The combination of substance use and psychiatric disorders is one of the most common comorbidities. The objective of this study was to perform a genome-wide association study of this comorbidity (Com), substance use alone (Subs), and psychiatric symptomatology alone (Psych) in the Mexican population. The study included 3914 individuals of Mexican descent.

Association of MGAT4C with major neurocognitive disorder in the Mexican population.

Background: Neurocognitive disorders (NCDs) are characterized by cognitive decline. Most genetic studies of NCDs have been focused on single-nucleotide polymorphism; other genetic variations, such as copy number variants (CNV), have been less explored. The aim of the present study was to explore CNVs associated with NCDs in a small sample of Mexican individuals and search for the frequency in a larger replication sample of individuals at high-risk for or diagnosed with NCDs.

The Identification of Admixture Patterns Could Refine Pharmacogenetic Counseling: Analysis of a Population-Based Sample in Mexico.

Pharmacogenetic analysis has generated translational data that could be applied to guide treatments according to individual genetic variations. However, pharmacogenetic counseling in some (admixed) populations may require tailoring to different patterns of admixture. The identification and clustering of individuals with related admixture patterns in such populations could help to refine the practice of pharmacogenetic counseling.

Sociodemographic and personal factors related to depressive symptomatology in the Mexican population aged 12 to 65.

Objective: To describe the prevalence of depressive symptoms in the Mexican population, aged 12 to 65 years, by identifying the main related socio-demographic and personal factors.

Methods: Data are drawn from the National Survey on Addictions 2008 (ENA 2008), a random, probabilistic, multistage study. A randomly selected sub-sample of 22,962 persons answered the section on depressive symptomatology, measured with the Center for Epidemiologic Studies Depression Scale (CES-D).

Comorbidity for alcohol use disorders and drug use in mexican-origin groups: comparison of data from national alcohol surveys in the U.S. And Mexico.

The comorbidity, separately, of alcohol dependence and consequences of drinking with illicit drug use is compared between Mexicans and Mexicans Americans, using data from the 1995 and 2000 U.S. National Alcohol Surveys (n = 830) and the 1998 Mexico National Household Survey on Addictions (n = 3313).

[Risky eating behaviors in student population in Mexico City: trends 1997-2003].

Objective: The main purpose of this study was to identify the trends of risky eating behaviors among student population in Mexico City in the period 1997-2003 and its relationship with sex age and family head educational level.

Methods: Data from the 1997 (N = 9,755), 2000 (N = 3,286) and 2003 (N = 3,062) Drug and Alcohol Prevalence in Student Population of Mexico City Survey's were analyzed. These are representative data of students of junior high, high school and technical schools in Mexico City, with a mean age of 14.

[Prevalence of violent events and post-traumatic stress disorder in the Mexican population].

Objective: To report the rate of exposure to different violent events, their demographic correlates, the prevalence of Post-Traumatic Stress Disorder (PTSD), and the impact on quality of life.

Material And Methods: The National Survey of Psychiatric Epidemiology is representative of the Mexican urban population aged 18 to 65. The survey was undertaken in 2001 and 2002 using the Composite International Diagnostic Interview (CIDI- 15) computerized version.

[Early onset depression: prevalence, course, and treatment seeking delay].

Objective: To estimate the prevalence of early onset depression in the Mexican population and compare its natural history, comorbidity and treatment latency between early onset and adult onset depression.

Material And Methods: The National Survey of Psychiatric Epidemiology (ENEP) is representative of the Mexican urban population aged 18 to 65. The diagnostic instrument is the Composite International Diagnostic Interview (CIDI).
