Purpose: To determine the association between types of food consumed, nutritional status (BMI) and caries in schoolchildren.
Material And Methods: A cross-sectional study was performed with 224 schoolchildren 6 to 12 years of age. DMFT/ dmft indices, level of oral hygiene, nutritional status as quantified by BMI and types of food consumed were determined in all participants.
Background: Salamanca, Mexico occupied fourth place nationally in contaminating emissions. The aim of the study was to determine the impact of air pollution on the frequency of pulmonary function alterations and respiratory symptoms in school-age children in a longitudinal repeated-measures study.
Methods: We recruited a cohort of 464 children from 6 to 14 years of age, from two schools differing in distance from the major stationary air pollution sources.
Objective: The purpose of this study was to assess the contribution of obesity on quality of a woman's life during pregnancy.
Study Design: At the Hospital of Gynecology and Obstetrics in León, Mexico, we followed-up 220 pregnant women (110 obese and 110 nonobese) who completed the 12-item short-form health survey at the beginning and during the third trimester of pregnancy.
Results: The mental component score was lower in obese than in nonobese women at the beginning of gestation and at the third trimester but increased in the entire group during pregnancy.
The authors studied the frequency, distribution, and factors associated with prediabetes (fasting glucose, 100-125 mg/dL) in rural and urban children from San Luis Potosí, León, and Querétaro in central Mexico. Family history, somatometry, and levels of fasting insulin, glucose, and lipids were collected in 1238 children 6 to 13 years of age. The authors found no cases of type 2 diabetes and a 5.

However, the relationship between heart sympathetic activity and left ventricular mass in normotensive obese subjects has not been studied.
Methods: We studied 103 male normotensive subjects (53 obese and 50 non-obese).
Background: In rats leptin increases sympathetic activity, and an inhibitory effect on leptin synthesis and release has been demonstrated for the catecholamines, both in adipocyte cell cultures and in healthy experimental animals. The aim of this study was to evaluate the relationship between leptin and heart sympathetic activity as well as changes in leptin levels after the administration of drugs that modify sympathetic activity.
Methods: We performed a randomized, blinded, before-after trial in 81 normotensive obese and non-obese subjects.
