[Use of lead-glazed ceramic as a source of exposure in children of marginalized indigenous zones of Oaxaca, Mexico].

Objective: To find out whether the use of lead-glazed ceramic (LGC) is associated with blood lead levels in indigenous schoolchildren from Oaxaca, México.

Materials And Methods: We evaluated LGC use at home as a primary source of lead exposure in 387 indigenous schoolchildren in Oaxaca in May 2001.

Results: We found an adjusted difference of 3.

Impact of the non-contributory social pension program 70 y más on older adults' mental well-being.

Background: In 2007, a non-contributory pension program was launched in rural areas of Mexico. The program consisted in a non-conditional cash transfer of US$40 monthly to all older adults (OA) aged 70 and over. We evaluate the effect of the program on mental well-being of its beneficiaries.

Short-term effect of physical activity and obesity on disability in a sample of rural elderly in Mexico.

Objective: To estimate the effects of physical activity (PA) and obesity on the cumulative incidence of disability on the basic activities of daily living in the elderly.

Materials And Methods: Longitudinal study. We selected 2477 participants aged 65-74 years from the impact evaluation study of a non-contributory pension program in Mexico.

Short-Term Impact of Anemia on Mortality: Evidence From a Sample of Mexican Older Adults.

Objective: To estimate the short-term (14 months) impact of anemia on mortality among Mexican older adults (OAs).

Method: Longitudinal analyses using data from a quasi-experimental study in a non-contributory pension program in Mexico with a sample of 3,621 OAs aged 65 to 74 years. Data on health, nutrition, life conditions, and mortality were gathered at both baseline and follow-up.

[Retrospective analysis of Mexican National Addictions Survey, 2008. Bias identification and correction].

Objective: To determine the presence of bias on the estimation of the consumption sometime in life of alcohol, tobacco or illegal drugs and inhalable substances, and to propose a correction for this in the case it is present.

Materials And Methods: Mexican National Addictions Surveys (NAS) 2002, 2008, and 2011 were analyzed to compare population estimations of consumption sometime in life of tobacco, alcohol or illegal drugs and inhalable substances. A couple of alternative approaches for bias correction were developed.

Effect of social capital and personal autonomy on the incidence of depressive symptoms in the elderly: evidence from a longitudinal study in Mexico.

Objectives: To estimate the effect of social capital (SC) and personal autonomy (PA) on the depressive symptoms (DS) in older people living in poverty.

Method: Longitudinal study of elderly participants in the impact evaluation study of a non-contributory pension program in Mexico. For this study we selected the group of older people without significant DS at baseline.

[National Survey of Vaccination Coverage (Influenza, pneumococcus and tetanus) in Mexican population of 60 years of age and older].

Objective: Determine Vaccination Coverage (VC) among adults 60 years of age and older (EP), for influenza, pneumococcal and tetanus vaccines, association with socio-demographic characteristics and heterogeneity at state level.

Material And Methods: Cross-sectional analysis based on information from 18 015 households visited in a national survey. General and vaccine information (self-report) for a randomly selected elder in each household is available.

Prediction of alterations in glucose metabolism by glucose and insulin measurements in early pregnancy.

Background And Aims: Abnormal dysglycemia during pregnancy increases morbimortality in women and newborns. This study evaluated early markers for that event. We undertook this study to estimate the incidence of dysglycemic events during pregnancy and to evaluate fasting glycemia, insulin and HOMA-IR index in early pregnancy as their predictors in order to compare their predictive capability for gestational diabetes (GD).

[Air pollution, bronchial asthma, and acute respiratory infections in minors, Habana City].

Objective: To identify the relationship between emergency visits for acute respiratory illnesses, acute bronchial asthma crisis (ABAC) and acute respiratory infections (ARI), in children less than 14 years of age, and the daily changes of air pollutant levels, in two central hospitals of Havana City, between October 1st 1996 and March 16 1998.

Material And Methods: An ecological time series study was conducted. We assessed the relationship between the presence of acute respiratory illnesses, ABAC, and IRA, and exposure to levels of particles less than 10 microg/m3 (PM10), smoke, and sulfur dioxide (SO2); negative binomial regression models were used to assess latency periods of one to five days as well as the cumulative effect of seven days before the emergency visit.

Predictors of bone mineral density in female workers in Morelos State, Mexico.

Background: Although several studies have identified factors associated with bone mineral density (BMD), little research is available on Mexican women.

Methods: A cross-sectional study was conducted in 1,622 female workers between 20 and 80 years of age at the Mexican Social Security Institute (IMSS), an integral part of the Mexican health system. It was carried out in Morelos, a Mexican state that borders Mexico City.
