Medical outcomes study social support survey (MOS-SSS) in patients with chronic disease: A psychometric assessment.

Purpose: Currently, information on the psychometric properties of the Medical outcomes study-social support survey (MOS-SSS) for patients with chronic disease in primary health care, suggests problems in the dimensionality, specifically predominant unidimensionality in a multidimensional measure. The aim of this study was to determine the internal structure (dimensionality, measurement invariance and reliability) and association with other variables.

Methods: A total of 470 patients with chronic disease from a Family Medicine Unit at the Instituto Mexicano del Seguro Social, IMSS, with a mean age of 51.

Association between mortality and cardiovascular diseases in the vulnerable Mexican population: A cross-sectional retrospective study of the COVID-19 pandemic.

Cardiovascular diseases (CVDs) continue to be the leading cause of death worldwide. Over the past couple of years and with the surge of the COVID-19 pandemic, mortality from CVDs has been slightly overshadowed by those due to COVID-19, although it was during the peak of the pandemic. In the present study, patients with CVDs (CVDs; = 41,883) were analyzed to determine which comorbidities had the largest impact on overall patient mortality due to their association with both diseases ( = 3,637).

Validity and Reliability of the Beck Anxiety Inventory (BAI) for Family Caregivers of Children with Cancer.

Currently, information about the psychometric properties of the Beck Anxiety Inventory (BAI) in family caregivers of children with cancer is not available; thus, there is no empirical evidence of its validity and reliability to support its use in this population in Mexico or in other countries. This study examined the psychometric properties of the BAI in family caregivers of children with cancer and pursued four objectives: to determine the factor structure of the BAI, estimate its internal consistency reliability, describe the distribution of BAI scores and the level of anxiety in the sample and test its concurrent validity in relation to depression and resilience. This cross-sectional study was carried out with convenience sampling.

[Social factors associated with tobacco and alcohol consumption in Mexican adolescents from populations under 100 000 inhabitants.].

Objective: To evaluate the social factors associated with tobacco and alcohol consumption in Mexican adolescents from populations under 100 000 inhabitants.

Materials And Methods: Cross-sectional study based on the National Health and Nutrition Survey (Ensanut100k). It included adolescents between 10-19 years.

[Depressive symptoms and serum levels of polyunsaturated fatty acids omega-3 and omega-6 among college students from Northern Mexico].

Introduction: Previous studies suggest that low consumption as well as low serum levels of polyunsaturated fatty acids (PUFA) omega-3 and a high omega-6/omega-3 ratio may be implicated in the etiology of depressive disorders, however, epidemiologic evidence is inconclusive.

Objective: To assess the relationship of serum levels of omega-3 fatty acids (docosahexaenoic [DHA], eicosapentaenoic [EPA], alpha-linolenic fatty acid [ALA]) and the omega-6 (arachidonic acid [AA])/EPA ratio with depressive symptoms among Mexican college students.

Material And Methods: A cross-sectional study that included 60 male and female participants (ages 18 to 24 years) with serum levels of EPA, DHA, ALA and AA.

Quality of reproductive healthcare for adolescents: A nationally representative survey of providers in Mexico.

Objective: Adolescents need sexual and reproductive health services but little is known about quality-of-care in lower- and middle-income countries where most of the world's adolescents reside. Quality-of-care has important implications as lower quality may be linked to higher unplanned pregnancy and sexually transmitted infection rates. This study sought to generate evidence about quality-of-care in public sexual and reproductive health services for adolescents.

[Sexual intercourse debut and associated factors in Mexican students aged 14-19 years in public schools].

Objective: To estimate the mean age of sexual intercourse debut (SID) and associated family and individual factors in 14-19-year-olds of both sexes in the 32 states of Mexico in 2007.

Methods: A cross-sectional study was conducted of a representative sample of 9,893 students aged between 14 and 19 years old. The data were collected through a self-administered, anonymous and voluntary questionnaire.

[Individual and family factors associated with depressive symptomatology in adolescents from public schools of Mexico].

Objective: To estimate the prevalence of depressive symptoms (DS) and to explore associated individual and family factors in high-school students from public schools of Mexico.

Materials And Methods: Cross-sectional study of a representative sample of 9 982 students aged between 14 and 19 years. Logistic regression models were used to estimate odds ratio (OR) with 95% confidence interval (CI95%).

[Gender role orientation and tobacco and alcohol use among youth in Morelos, Mexico].

Objective: To quantify the association between gender role orientation and tobacco and alcohol use among young people of the State of Morelos.

Material And Methods: A cross-sectional study was conducted from October 1997 to August 1998, among 200 men aged 17 to 64 years referred to the Oncology Department of the National Institute of Perinatology in Mexico City.
