[Inadequate feeding practices between month 4 and 6 and its association with nutritional deficit in a group of Venezuelan lactating infants].

Adequate practices in food consumption are fundamental for child health, nutrition and growth. In order to detect associations between the inadequate practice of exclusive breastfeeding (EBF), predominant and/or complimentary in the first 4 to 6 months of life, and deficiencies in growth and malnutrition, 240 lactating infants younger than 24 months were evaluated in a low income urban area in the city of Valencia, Venezuela (2006). For the practice of breastfeeding, two groups were identified: children who received EBF in that period of time, and those who did not receive it (No EBF).

[Validity of the energy/protein index in the detection of overweight in low income Venezuelan preschoolers].

The validity of the energy/protein index (EPI) in the detection of overweight was assessed in 163 low income children (four to six years old) from Valencia, Venezuela. Weight, height, arm circumference, and skinfolds were taken. Weight for height (W/H), limb fat area (LFA), and EPI were calculated.

[Body mass index in a group of Venezuelan pregnant women and its relationship with the newborns' anthropometry].

To assess the relationship between maternal body mass index (BMI) at early gestation and the newborns' anthropometry, 105 mother-infant dyads from a public Maternity Hospital in Valencia Venezuela, were studied during 1998-2000. Weight and height of adult women between 10 and 15 weeks of gestation were used to calculate BMI according to Atalah's reference (Low weight, Normal, Over weight). Term newborns were assessed using gestational age calculated according to the Capurro method.

[Lymphocyte subpopulations in preschool Venezuelan children of high socioeconomic status].

Nutrition is a critical determinant of immune response being the most common cause of immunodeficiency in the world. 104 preschool children, apparently healthy, from a private school were chosen to determine lymphocyte subpopulations and to evaluate its relationship to the anthropometric nutritional status and serum zinc. Nutritional status was measured by the indicator weight for height, lymphocyte subpopulations by flow cytometry and serum zinc by atomic absorption spectrophotometry A high percentage of the population (87.
