Association of Helicobacter pylori infection and height of Mexican children of low socioeconomic level attending boarding schools.

This study evaluated the association between Helicobacter pylori infection and height in a population of schoolchildren of a low socioeconomic level regarding growth-related micronutrient status. It was a cross-sectional study of 685 children 5-13 years of age. Height and weight were recorded, a (13)C urea breath test was performed for detection of H.

[Contribution of processed foods to the energy, macronutrient and fiber intakes of Mexican children aged 1 to 4 years].

Objective: To classify the foods consumed by Mexican children 1-4 years in three food categories according to the preparation process and temporality: a) Processed Modern Foods (PMF), b) Processed Traditional Foods (PTF) and c) Non-Processed Foods.

Material And Methods: Twenty-four-hour dietary recalls were collected from the National Nutrition Survey 1999 in children 1-4 years (n =1070). The contribution of each food category to the total energy, macronutrient and fiber intakes was analyzed.

Multiple micronutrient supplementation and dietary energy intake in pregnant women.

Objective: To compare dietary intake of women supplemented with multiple micronutrients (MM) or iron only during pregnancy.

Design: Randomized, double-blind, controlled community-based trial.

Setting: One semi-urban community in Central Mexico.

Poor compliance with appropriate feeding practices in children under 2 y in Mexico.

We evaluated breast-feeding and complementary feeding practices in Mexico, using data from a national probabilistic survey carried out in 17,716 households, with regional and urban-rural representation. Mothers of children <2 y old (n = 3,191) reported duration of breast-feeding and the ages of usual introduction of 7 food groups. The Kaplan-Meier method was used to estimate the median time of feeding events.

Effect of prenatal multiple micronutrient supplements on maternal weight and skinfold changes: a randomized double-blind clinical trial in Mexico.

Background: Recent trials of prenatal multivitamin-mineral supplements have yielded mixed findings for outcomes such as birth size, but the benefits of prenatal multivitamin-mineral supplements for maternal outcomes are unknown.

Objective: The main objective of this study was to examine the effect of prenatal multiple micronutrient supplements (MM) compared to iron only (FE) supplements on changes in maternal weight and body composition during pregnancy and the early postpartum period.

Methods: A randomized double-blind clinical trial was conducted in semi-rural Mexico.
