[Preliminary analysis in the implementation of a health program in child nutrition].

In the view of the importance of nutrition for the eventual physical and psychological development of children, several ways to control the outcome of malnutrition, both due to excess and to defect, have been reported. Before introducing the adequate measures for the prevention and early diagnosis of malnutrition and obesity, the nutritional status of the children aged between 1-7 years was evaluated in the assigned population by means of the Shukla's index. In 681 evaluated children, 42 obese, 23 with malnutrition, 81 overweight and 105 with risk of malnutrition were detected. This prevalence of malnutrition and obesity warrants the implementation of screening measures for the nutritional status in children from the health center. A protocol to this end is outlined in the present article.

[Policies and programs of food and nutrition in Mexico].

Mexico has a long-standing history of programs and policies oriented to improve the nutrition of vulnerable groups. However, malnutrition represents one of the main public health challenges in Mexico. This article provides a historic perspective of the main strategies, programs and policies that have been carried out in Mexico, as well as a detailed analysis of their design, implementation, and selected results. Finally, some critical issues related to food policies implemented in Mexico are identified.

Maternal body mass index and pregnancy outcome in the Nutrition Collaborative Research Support Program.

This paper uses data from the Nutrition CRSP in Egypt, Mexico and Kenya to examine relationships between maternal BMI and pregnancy outcome. Women were studied from the periconceptional period up to 6 months of lactation. No women in Egypt or Mexico, and only two in Kenya where periods of food shortage occurred, had a BMI < 18 at conception. Women with a lower BMI in Mexico and Kenya gained more weight and fat in pregnancy and lost more weight and fat during lactation. These counter-intuitive relationships affect the interpretation of weight and body composition measures used to assess energy adequacy during pregnancy and lactation. Lower pre-pregnancy BMI predicted lower infant weights at birth and was a risk factor for low birthweight in Kenya. At 3-6 months post partum, maternal BMI was less strongly related to infant size, and the lean body mass component of BMI appeared to be a more important predictor than fatness.

Nutrition in pregnant or lactating rats programs lipid metabolism in the offspring.

Epidemiological studies in human show that size in early life is related to blood cholesterol concentrations in adult life, raising the hypothesis that early nutrition programs later lipid metabolism, affecting risk for later vascular disease. Here, we tested the hypothesis that nutrition during pregnancy or lactation in the rat programs lipid metabolism in the offspring, studied in adult life (mean 6 months). Rats (n 35) from normally-fed dams (controls) were compared with (1) rats (n 22) from dams protein-restricted in pregnancy and lactation; (2) rats (n 9) born to normally-fed mother crossed to protein-restricted lactating dams and (3) those (n 9) born of protein-restricted dams and crossed to normally-fed lactating animals. In these latter three groups the offspring showed long-term reduction in plasma cholesterol, HDL-cholesterol and triacylglycerol concentrations compared with controls. The effects were predominantly in males. These findings suggest that in the rat the sensitive period for nutritional programming of cholesterol and triacylglycerol metabolism is both pre- and postnatal (pre-weaning) and that rats may be 'indirectly' programmed by altering the maternal nutritional milieu during gestation or lactation. Whilst it has been hypothesized that early human undernutrition programs risk for vascular disease, one aspect of undernutrition, low maternal protein intake, in this rat model programmed lower plasma cholesterol and triacylglycerol concentrations.

Position of the American Dietetic Association: food insecurity and hunger in the United States.

It is the position of the American Dietetic Association that systematic and sustained action is needed to bring an end to domestic food insecurity and hunger and to achieve food and nutrition security for all in the United States. The Association believes that immediate and long-range interventions are needed, including adequate funding for and increased utilization of food and nutrition assistance programs, the inclusion of food and nutrition education in all programs providing food and nutrition assistance, and innovative programs to promote and support the economic self-sufficiency of individuals and families, to end food insecurity and hunger in the United States. Food insecurity continues to exist in the United States, with over 38 million people experiencing it sometime in 2004. Negative nutritional and nonnutritional outcomes have been associated with food insecurity in adults, adolescents, and children, including poor dietary intake and nutritional status, poor health, increased risk for the development of chronic diseases, poor psychological and cognitive functioning, and substandard academic achievement. Dietetics professionals can play a key role in ending food insecurity and hunger and are uniquely positioned to make valuable contributions through provision of comprehensive food and nutrition education, competent and collaborative practice, innovative research related to accessing a safe and secure food supply, and advocacy efforts at the local, state, regional, and national levels.
