OBJECTIVE:To investigate the relationship between physical activity during the second trimester pregnancy and low birth weight, preterm birth, and intrauterine growth restriction. METHODS:Case-control study including 273 low birth weight newborns and 546 controls carried out in the city of São Paulo, Southeastern Brazil, in 2005. Low birth weight cases were grouped into two subsamples: preterm birth (n=117) and intrauterine growth restriction (n=134), with their related controls. Information was collected by means of interviews with mothers shortly after birth and transcription of medical records. Data were analyzed using conditional multiple and hierarchical logistic regression. RESULTS:Light physical activity for over 7 hours per day was shown to be protective against low birth weight (adjusted OR=0.61; 95% CI 0.39-0.94) with a dose-response relationship (p-value for trend=0.026). A similar trend was found for intrauterine growth restriction (adjusted OR=0.51; 95% CI 0.26-0.97). Homemaking activities were associated as a protective factor for both low birth weight and preterm birth (p-value for trend=0.013 and 0.035, respectively). Leisure-time walking was found to be protective against preterm birth. CONCLUSIONS:Mild physical activity during the second trimester of pregnancy such as walking has an independent protective effect on low birth weight, preterm birth, and intrauterine growth restriction. Low birth weight is an important public health issue in both developed and developing countries. It is the main factor infl uencing health and nutritional conditions and child survival, and is also associated with occurrence of chronic diseases in adult life. 10Over the past two decades -in contrast to the declining trend seen for many health indicators, such as child mortality, postnatal malnutrition, and malnutrition among adult women -prevalence of low birth weight (under 2,500 grams) has remained stable, or even increased in cities of Southern and Southeastern Brazil. There are two major processes that can lead to low birth weight: preterm birth and restricted intrauterine growth. In the city of Pelotas, over the last two decades, Barros et al 2 observed a slight increase in the prevalence of low birth weight and a greater increase in preterm birth (6.3% in 1982 to 16.2% in 2004), whereas prevalence of intrauterine growth restriction (IUGR) remained unaltered. RESUMO OBJETIVO:Analisar a relação entre atividade física durante o segundo trimestre de gestação e baixo peso ao nascer, prematuridade e restrição de crescimento intra-uterino. MÉTODOS:Estudo de caso-controle realizado no município de São Paulo, em 2005. Foram estudados 273 recém-nascidos de baixo peso e 546 controles. Dentre os casos foram selecionadas duas sub-amostras: 117 nascimentos pré-termo e 132 com restrição de crescimento intra-uterino (n=132) e seus respectivos controles. As informações foram obtidas mediante entrevistas com as puérperas e transcrição de dados dos prontuários. Foram realizadas análises de regressão logística múltipla...

“…26 We evaluated physical activity during housework, work outside home, leisure time, and transportation. 22 Time spent on each of these activities was calculated by multiplying frequency by duration, expressed in min or hours per day. The compendium of physical activities 1 was used to determine energy cost and classify activities.…”

“…In dysphagia, the intra-or interrater discrepancy may impact the decision to prescribe treatments or the choice between performing exercises and using compensatory maneuvers 7 . The choice of an evaluation method is a critical issue in data analysis for instrument validation because it should represent the greatest possible accuracy 27 . Two statistical methods were used to assess the reproducibility of the VF analysis protocol and showed high interrater reliability.…”

-Background: Videofluoroscopy is considered the "gold standard"procedure for the evaluation of swallowing by most units that treat patients with dysphagia, having a great impact in decision making, not only in therapeutic terms, but also in determining the prognosis. Aim: To propose and to verify the reproducibility of the results of a perceptual two-dimensional videofluoroscopic protocol for the analysis of the pharyngeal phase of swallowing in a population of healthy adults. Methods: Participants were 20 healthy adults, of both genders, with ages between 50 and 65 years. Videofluoroscopy was performed during the swallow of the following consistencies: 10 ml of liquid; 7 ml of paste; and half a "salt and water" biscuit. The protocol was composed by four parts: assessment of the pharyngeal transit time; assessment of the duration of the tongue base movement to the posterior pharyngeal wall; valleculae residue ratio; assessment of penetration/aspiration. Statistical analysis involved the assessment of data reproducibility between raters and analysis of the quantitative data regarding gender. Results:Comparison among raters indicated that data was highly reproducible. No significant differences were found between genders for pharyngeal transit time; for the duration of the tongue base movement to the posterior pharyngeal wall; and for the valleculae residue ratio. Conclusion: The perceptual two-dimensional videofluoroscopy analysis demonstrated to be a reproducible method. Valleculae residue was present in 40% of the study sample, suggesting that this parameter alone does not indicate alterations of the pharyngeal phase of swallowing. RESUMO -Racional:A videofluoroscopia é considerada o procedimento "padrão-ouro" para avaliação da deglutição pela maioria das unidades que atendem pacientes com disfagia, tendo grande impacto na tomada de decisão, não só em termos terapêuticos, como também na determinação do prognóstico. Objetivo: Propor e verificar a reprodutibilidade de protocolo de análise videofluoroscopica bidimensional perceptual da fase faríngea da deglutição em uma população de adultos saudáveis. Métodos: Participaram desta pesquisa 20 indivíduos saudáveis, de ambos os gêneros, com idades entre 50 e 65 anos. O exame foi realizado durante a ingestão de "alimentos" com as seguintes consistências: 10 ml de líquido; 7 ml de pastoso; e meio biscoito do tipo "água e sal". O protocolo proposto foi composto de quatro partes: avaliação do tempo de trânsito faríngeo; avaliação da duração do contato da base de língua na parede posterior da faringe; avaliação da porcentagem de resíduo alimentar em valécula; avaliação de penetração e aspiração na árvore respiratória. A análise estatística envolveu a avaliação da reprodutibilidade do método de análise entre avaliadores e a análise dos dados quantitativos, levando-se em consideração os gêneros. Resultados: Pela análise comparativa entre os avaliadores houve alta reprodutibilidade. Não foram encontradas diferenças estatisticamente significantes para o tempo de trâns...

Background: Being born small for gestational age (SGA) is a known risk factor for greater neonatal mortality and disease in later life. Some determinants of the incidence of SGA newborns have been studied but little is known about the role of leptin in the beginning of pregnancy. Objectives: To investigate the effect of serum leptin concentration in the 1st gestational trimester on the incidence of SGA newborns and to identify other determining factors in the occurrence of SGA. Methods: Prospective study with 195 pairs of mothers and their children monitored in Rio de Janeiro, Brazil. The dependent variable was SGA newborns, while the independent variables were sociodemographic, reproductive, anthropometric and biochemical variables. Statistical analysis was performed by means of logistic regression. Results: The incidence of SGA was 11.3% (CI 95%: 7.31–16.46). The results showed that low concentrations (lowest tertile compared to 2nd and 3rd tertiles) of leptin (RR = 5.26; CI 95%: 1.91–9.56), insufficient gestational weight gain (RR = 3.16; CI 95%: 0.98–7.38), low stature (RR = 3.94; CI 95%: 1.22–8.57) and alcohol consumption during gestation (RR = 5.92; CI 95%: 1.44–12.92) were risk factors for SGA. Conclusions: Lower leptin concentrations were associated with a significant risk for SGA after adjusting for confounding variables. Maternal serum leptin at the beginning of gestation can be used as a marker for the early detection of SGA.
