BackgroundNon-nutritive sucking habits (NNSH) are very common during childhood. However, if these habits were maintained for 36 months of age or more, they are considered to be prolonged (PNNSH) and can cause occlusal, physiological and esthetic changes. There is controversy about their prevalence and whether perinatal, social, demographic and health characteristics influence their onset and duration. So, the objectives of this study are to estimate the prevalence of PNNSH and to evaluate perinatal, early life and school age factors associated with their occurrence in children.MethodsA sample of 1,463 children aged 7–11 years born in Ribeirão Preto (RP-1994) and São Luís (SL-1997/98), Brazil, was reevaluated at school age in 2004/05. Birth weight, gestational age and perinatal variables were obtained at birth. Type of feeding, occurrence and duration of finger and pacifier sucking were recorded retrospectively at school age. PNNSH were defined when persisted for 36 months of age or more. Crude and adjusted prevalence ratios (PR) were estimated by Poisson regression (alpha = 5%).ResultsPrevalence of PNNSH was higher in RP (47.6%) than in SL (20.2%) – (p < 0.001). Perinatal variables were not associated to PNNSH, whilst female sex (PR = 1.27 in RP; PR = 1.47 in SL) and bottle feeding for 24 months or more (PR = 2.24 in RP; PR = 2.49 in SL) were risk factors in both locations. Breast feeding for 12 months or more (PR = 0.53 in RP; PR = 0.31 in SL) was associated with lower prevalence of PNNSH in both places. In SL, children whose mothers lived in consensual union (PR = 1.62) and worked outside the home (PR = 1.51) showed higher prevalence of PNNSH compared to their counterparts.ConclusionsPrevalence of PNNSH was high especially in RP and was not associated with perinatal variables. In both cities there was an association between female sex, shorter breast-feeding duration, longer bottle feeding duration and higher prevalence of PNNSH.

BackgroundRecent studies have raised controversy regarding the association between cesarean section and later obesity in the offspring. The purpose of this study was to assess the association of cesarean section with increased body mass index (BMI) and obesity in school children from two Brazilian cities with distinct socioeconomic backgrounds.MethodsTwo birth cohorts respectively born in 1994 in Ribeirao Preto, a wealthy city in Southeast, and in 1997/98 in Sao Luis, a less wealthy city in Northeast of Brasil, were evaluated. After birth, 2,846 pairs of mothers-newborns were evaluated in Ribeirao Preto and 2,542 in Sao Luis. In 2004/05, 790 children aged 10/11 years were randomly reassessed in Ribeirao Preto and 673 at 7/9 years in Sao Luis. Information on type of delivery, maternal and child characteristics, socioeconomic position and anthropometric measurements were collected after birth and at school age. Obesity was defined as BMI ≥ 95th percentile at school age.ResultsObesity rate was 13.0% in Ribeirao Preto and 2.1% in Sao Luis. Cesarean section was associated with obesity and remained significant after adjustment only in Ribeirao Preto [OR = 1.74 (95% CI: 1.04; 2.92)]. The association between cesarean section and BMI remained significant after adjustment for maternal schooling, maternal smoking during pregnancy, duration of breastfeeding, gender, birth weight and gestational age, type of school and, only in Sao Luis, pre-pregnancy maternal weight. In Ribeirao Preto children born by cesarean section had BMI 0.31 kg/m2 (95%CI: 0.11; 0.51) higher than those born by vaginal delivery. In Sao Luis BMI of children born by cesarean section was 0.28 kg/m2 higher (95%CI: 0.08; 0.49) than those born by vaginal delivery.ConclusionA positive association between cesarean section and increased BMI z-score was demonstrated in areas with different socioeconomic status in a middle-income country.

RESUMO -O peso e a idade gestacional são critérios relevantes para avaliação das condições de nascimento das crianças. O objetivo do presente estudo foi caracterizar e comparar o desempenho comportamental de uma coorte de crianças estratificada pelo peso ao nascer e pelo peso ao nascer em relação à idade gestacional. Avaliaram-se, aos 10/11 anos, 677 crianças por meio do Questionário de Capacidades e Dificuldades. Verificou-se, com significância estatística, os seguintes resultados: o grupo Baixo Peso apresentou mais sintomas emocionais que o grupo Peso Normal; o grupo Muito Baixo Peso mostrou mais hiperatividade em comparação aos outros; o grupo Pequeno para a Idade Gestacional apresentou mais dificuldades no escore total e mais sintomas emocionais em relação aos demais grupos. Concluiu-se que a estratificação por dois critérios permitiu a identificação de dificuldades específicas quanto ao desempenho comportamental.Palavras-chave: peso ao nascer, idade gestacional, comportamento, estudos de coortes Behavior of School Children Stratified by Birth Weight and Gestational AgeABSTRACT -Weight and gestational age are relevant criteria for assessing the conditions of childbirth. The goal of the present study was to characterize and compare the behavior of a cohort of children stratified by two criteria: birth weight and birth weight in relation to the gestational age. At the ages of 10 and 11 years, 677 children were evaluated by the Strengths and Difficulties Questionnaire. The following statistically significant differences were observed: the low weight group had more emotional symptoms than the normal weight group; the very low weight group had more hyperactivity compared to other groups; and the small in relation to the gestational age group had more difficulties with respect to the total score and emotional symptoms in relation the other groups. It was concluded that the stratification by two criteria allowed the identification of specific difficulties in behavioral performance.
