BACKGROUND
Vitamin A deficiency (VAD) is endemic in Brazil and health professionals have difficulty in recognizing its subclinical form. In addition, serum retinol concentrations do not always represent vitamin A status in the organism.
OBJECTIVE
To identify VAD in preschool children by the serum
OBJECTIVE
The survey will reveal current status of subclinical vitamin A deficiency (SVAD) and explore its affecting factors in children of China.
METHODS
Totally 8 669 children aged under 6 years were randomly selected from 14 provinces for clinical examination, health and dietary questionnaire and
The objective of this study was to develop community based screening indicators for identifying areas at risk of vitamin A deficiency. Three hundred children aged 24-71 months in 12 villages of 3 provinces who were previously identified to have various degrees of vitamin A deficiency were randomly
To identify the prevalence of zinc deficiency in a population with high prevalence of vitamin A deficiency; to verify whether zinc deficiency is associated with vitamin A deficiency in the population studied; to verify risk factors for zinc deficiency (sex, age, diarrhea and fever).
Cross-sectional
Infection is an important cause of morbidity throughout childhood. Poor micronutrient status is a risk factor for infection-related morbidity in young children, but it is not clear whether these associations persist during school-age years. We examined the relation between blood concentrations of
OBJECTIVE
To identify the prevalence of iron deficiency in the population studied, as well as verifying if such deprivation is associated with vitamin A deficiency.
METHODS
One hundred seventy-nine children, > or = 24 months and < 72 months of age, with no diarrhea and/or fever at collection were

Vitamin A supplementation reduces mortality in young children in areas of endemic vitamin A deficiency. However, it has no impact on the incidence of common morbidities. This discrepancy has been explained by an impact on case fatality, although with the exception of hospitalized measles cases,
The relationship of vitamin A deficiency and child survival has been documented in a number of studies but not in others, yet the relationship of vitamin A with child morbidity remains controversial. We prospectively examined the relationship of dietary vitamin A intake and the incidences of
Developmental eye defects such as coloboma are a significant cause of visual morbidity in children, and are more common in India than elsewhere. The possible role of environmental factors in the aetiology of these conditions was investigated by studying birth order, symptoms of vitamin A deficiency
BACKGROUND
Vitamin A deficiency is a significant public health problem in low- and middle-income countries. Vitamin A supplementation provided to infants less than six months of age is one of the strategies to improve the nutrition of infants at high risk of vitamin A deficiency and thus potentially
Vitamin A supplementation (VAS) in the postpartum period improves the vitamin A concentration of breast milk and vitamin A status is an important predictor of childhood survival. It is also known that Vitamin A Deficiency (VAD) is more prevalent in HIV-infected women. This study
