“…Os fatores de risco da anemia mais citados na literatura são baixa renda familiar e escolaridade materna, falta de acesso aos serviços de saúde, precariedade nas condições de saneamento e a dieta inadequada em ferro [1][2][3][4] . Entre os fatores associados à dieta, encontram-se baixa ingestão de ferro e de alimentos facilitadores da sua absorção, deficiência de outros nutrientes envolvidos no metabolismo do ferro, como vitamina A e presença de inibidores da sua absorção [5][6][7] .…”

ResumoObjetivo: Este estudo tem como objetivo identificar, utilizando modelagem estatística, os fatores de risco da anemia em crianças de 6 a 59 meses de idade no estado de Pernambuco, contemplando aspectos socioeconômicos e da dieta.Métodos: A amostra constou de 746 crianças de 6 a 59 meses do estado de Pernambuco, nas quais foram realizados dosagem de hemoglobina e inquérito dietético recordatório de 24 horas. Foi analisado o risco de anemia em relação às variáveis socioeconômicas e de consumo alimentar, utilizando modelos de análise multivariada. AbstractObjective: The objective of this study was to use statistical modeling to identify risk factors for anemia in children aged 6 to 59 months in the state of Pernambuco, covering socioeconomic and dietary aspects. Methods:The sample comprised 746 children aged between 6 and 59 months from the state of Pernambuco. Their hemoglobin was assayed and a 24-hour dietary recall performed. Risk of anemia was analyzed with relation to socioeconomic variables and to dietary intakes, using multivariate analysis models. Results:The risk factors for anemia were: a high proportion of calories from cow's milk, low density of nonheme iron, low age and low maternal educational level; age was the most prominent factor, with children under 24 months exhibiting 3.61 times greater risk of being anemic than the older children. Conclusions:This study confirms the need for a clear picture of the dietary intake of children in Brazil, in order that associations with anemia can be better understood. Our results revealed that the dietary factors which were most responsible for risk of anemia were a greater proportion of calories from cow's milk and lower density of nonheme iron, in addition to age below 24 months and low maternal educational level.J Pediatr (Rio J). 2007;83(1):39-46: Iron deficiency anemia, epidemiology, risk factors, food intake, child nutrition. IntroduçãoA anemia ferropriva resulta da interação de múltiplos fatores etiológicos que levam a um desequilíbrio entre as necessidades do organismo e a quantidade absorvida de ferro.Os fatores de risco da anemia mais citados na literatura são baixa renda familiar e escolaridade materna, falta de acesso aos serviços de saúde, precariedade nas condições de saneamento e a dieta inadequada em ferro [1][2][3][4]

“…29 Birth weight had a significant and independent association with the concentration of hemoglobin, which is similar to data observed by other researchers. 16,22,30 The direct relationship between mean hemoglobin and birth weight indicates that the iron reserves of children born full term with low birth weight put them at risk of developing anemia during infancy. 9 There was no relationship between the hemoglobin levels of the child and the mother's educational level or with the quality of prenatal care.…”

Objective: To verify the influence of breastfeeding type and of maternal anemia on hemoglobin concentration in 6-month-old infants.Methods: This was a cross-sectional study nested in a community-based, randomized and controlled intervention study that aimed to prolong the duration of exclusive breastfeeding during the first 6 months of life. This study was conducted in four towns in the Brazilian state of Pernambuco and newborn infants were recruited from March to August of 2001. The hemoglobin concentrations of 330 mothers and infants were assayed and type of breastfeeding was assessed 6 months after delivery. Multivariate linear regression analysis was used to identify factors that independently contributed to the infants' hemoglobin concentration. Results:The type of feeding had no influence on the hemoglobin concentration in the sample as a whole, however, there was a significant difference when the "exclusive + predominant breastfeeding" subset of infants was analyzed, with the children of anemic mothers exhibiting a reduction of 0.7g/dL in median hemoglobin. Mothers' hemoglobin level, type of flooring at home, type of delivery, and birthweight all significantly contributed to the variation in the infants' hemoglobin concentration. Conclusions:In contrast with type of breastfeeding, maternal anemia did have an influence on the hemoglobin levels of 6-month-old infants, even when only children on "exclusive + predominant breastfeeding" were analyzed. These findings highlight the need to prevent maternal anemia before conception, during pregnancy and throughout lactation.

Birthweight is recognized to be a determinant of a full term infant's early growth pattern; however, few studies have explored whether this effect is sustained into school age, especially in developing countries. We have used a cohort study from North East Brazil to investigate factors determining the anthropometric status of eight-year-old children born at full-term with low or appropriate weight. A cohort of 375 full-term infants was recruited at birth in six maternity hospitals between 1993 and 1994, in a poor region of the interior of the State of Pernambuco. At the age of 8 years, 86 born with low birthweight and 127 with appropriate birthweight were traced. Multivariable linear regression analyses were used to identify the net effect of socioeconomic conditions, maternal nutritional status and child factors on weight-for-age and height-for-age. An enter approach was used to estimate the contribution of different factors on child anthropometry. Birthweight had little influence on child nutritional status at school age. Maternal BMI and height together were the biggest contributors to variation in child weight-for-age (12.3%) and height-for-age (13.2%), followed by family socioeconomic conditions. Maternal height as a proxy of maternal constraint was the single factor that best explained the variation in both indices (6.2% for weight-for-age and 11.1% for height-for-age). Haemoglobin level measured at eight years made a small but significant contribution to variation in height-for-age (5.6%) and weight for age (1.4%). Maternal nutritional status, reflecting genetic inheritance and the poor socioeconomic conditions of this population, was the most important determinant of the nutritional status of children at school age, rather than birthweight.
