Determinants of Vitamin D Status in Healthy Young Adults from Mexico City.

Background And Aims: Vitamin D deficiency is a global health problem. The determinants of this deficiency have not been evaluated in developing countries such as Mexico. Thus, this study aimed to determine vitamin D intake and sun exposure and its relationship with plasma concentrations of 25-hydroxyvitamin D -25(OH)D- in young adults from Mexico City.

Aflatoxin exposure in adults in southern and eastern Mexico in 2018: A descriptive study.

Objective: To estimate the frequency of detection and levels of aflatoxin B-lysine adduct (AFB-lys), an important hepatocellular carcinoma (HCC) risk factor, in eastern and southern Mexico.

Materials And Methods: We determined serum AFB-lys using mass spectrometry in a representative sample of 952 adults (weighted n = 7,493,354) from five states (Campeche, Chiapas, Tamaulipas, Veracruz and Yucatán) in 2018. We calculated overall and subgroup-specific frequency of detection and 95% confidence intervals (95%CI) and median AFB-lys levels and quartiles.

Vitamin D Receptor Gene Polymorphisms, β-cell Function, and Vitamin D Status in Non-obese Mexican Adults.

Background: FokI (rs2228570 T>C) and BsmI (rs1544410 A>G) polymorphisms of the vitamin D receptor (VDR) have been associated to abnormal glucose metabolism and could be inversely associated with β-cell function (BCF) and vitamin D status. There is a lack of information about this topic in the Mexican population.

Aim Of The Study: To evaluate the relationship between VDR gene polymorphisms FokI and BsmI with BCF and vitamin D status in a population of non-obese Mexican adults.

[Not Available].

Objective: To describe the current status of anemia and iron deficiency (ID), as well as associated sociodemographic characteristics, in older adults (OA). Materials and meth-ods. Serum and capillary blood samples from a sample of OA participants (n=2 902) from the Ensanut 2018-19 were analyzed.

[Trend in the prevalence of anemia in Mexican women of childbearing age from 2006-2016. Ensanut MC 2016].

Objective: To describe the anemia prevalence among women from 20 to 49 years from 2016-Halfway National Health and Nutrition Survey (Ensanut MC 2016) and compare the trends in 2006, 2012 and 2016 surveys, as well as its association with dietary iron and sociodemographic factors.

Materials And Methods: The methodological design of Ensanut MC is fully comparable with Ensanut 2006 and 2012. Capillary hemoglobin (Hb) was obtained and those values <120 g/L were classified as anemic.

Validation of Masimo Pronto 7 and HemoCue 201 for hemoglobin determination in children from 1 to 5 years of age.

Objective: To evaluate the accuracy and precision of HemoCue 201 (HemoCue) and Masimo Pronto 7 (Masimo) devices for measuring hemoglobin (Hb) in epidemiological studies, having venous blood samples as a gold standard.

Material And Methods: We measured Hb concentrations in a field sample of 148 children from one to five years of age. Masimo and HemoCue were used for capillary blood samples and an automatic analyzer for venous blood samples.

The Effects of Dietary Iron and Capsaicin on Hemoglobin, Blood Glucose, Insulin Tolerance, Cholesterol, and Triglycerides, in Healthy and Diabetic Wistar Rats.

Objective: Our aim was to assess the effects of dietary iron, and the compound capsaicin, on hemoglobin as well as metabolic indicators including blood glucose, cholesterol, triglycerides, insulin, and glucose tolerance.

Materials And Methods: Our animal model was the Wistar rat, fed a chow diet, with or without experimentally induced diabetes. Diabetic males were fed control, low, or high-iron diets, the latter, with or without capsaicin.

[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.

[Nutritional status of vitamin A in preschoolers with ocular diseases].

The purpose was to evaluate the nutritional status of vitamin A in preschool children with ocular diseases attending to the Hospital Civil of Guadalajara. In a cross sectional design 100 preschool children between 24 and 71 mo of age with ocular diseases were included. Vitamin A intake was evaluated by 24 h dietetic recall, plasma Retinol concentration by high pressure liquid chromatography (HPLC); and, conjunctiva impression cytology (CIC) was carried out by a trained pathologist.

Anemia in Mexican women: results of two national probabilistic surveys.

Objective: To describe the prevalence of anemia in Mexican women and analyze its trends with information from the last two national nutrition surveys.

Material And Methods: The prevalence of anemia in women was analyzed. Anemia was adjusted by socioeconomic profile and by potentially explanatory variables.

[Health and nutrition status of older adults in Mexico: results of a national probabilistic survey].

Objective: To describe health and nutrition status in the elderly population in Mexico.

Material And Methods: Information from 5,480 adults (>60 years) obtained by the National Health and Nutrition Survey (ENSANUT-2006) was analyzed. Frequencies, means, and confidence intervals at 95% were obtained and adjusted for design effect.

[Factors associated with nutritional supplement consumption in Mexican women aged 12 to 49 years].

The objectives of this analysis are to identify the types of nutritional supplements (NS) commonly used and explore the associations between NS consumption and socio-demographic characteristics, nutritional status, measured as BMI, and anemia in a nationally representative sample Mexican women aged 12 to 49 years (n = 15,936) who participated in the Mexican National Nutrition Survey in 1999. Data on NS consumption and the other characteristics of interest were collected. We calculated the probability (P) of supplement consumption using logistic regression.
