Distortion and dissatisfaction with body size per the demographic and academic characteristics and the nutritional status of university students

To identify the prevalence of distortion and dissatisfaction with the body size of Brazilian university students, and establish their relationship with the demographic and academic characteristics and the anthropometric nutritional status. The sample consisted of students from a public university in the state of São Paulo. The Figure Rating Scale (FRS) for Brazilian adults was used as an instrument. The participants selected the figure that corresponded to the current body and another one for the desired body. The prevalence of distortion and dissatisfaction with body sizewas calculated with 95% confidence interval (95% CI). The association between the variables was evaluated by the Chi-Square Test (χ2). The significance level of 5% was adopted. A total of 356 students (women=71.63%) with a mean age of 20.95 (SD=2.55) years participated. The prevalence of distortion and dissatisfaction with body size was 73.03% (95% CI=68.23­77.83) and 79.49% (95% CI=75.3­83.68), respectively. There was a high prevalence of distortion with body size among individuals with low weight (χ2=9.523, p=0.009). Students who distorted the body size (52.31% [95% CI=47.12­57.50]) underestimated their body size. The type of distortion was related to sex (χ2=26.35, p<0.001), physical activity (χ2=4.51, p=0.034), use of supplements (χ2=4.62, p=0.032), andthe anthropometric nutritional status (χ2=9.05, p=0.011). Students dissatisfied with the body (58.66% [95% CI=52.92­64.40]) wished to reduce the body size. The type of dissatisfaction was related to sex (χ2=5.79, p=0.016) and anthropometric nutritional status (χ2=89.83, p<0.001). The prevalence of body size underestimation was higher among men, students who practice physical activity, subjects using dietary supplements and underweight individuals. The wish to decrease body size was higher among women and overweight/obese individuals.(AU)

Influência da anemia em gestantes sobre o peso ao nascer: um estudo da Coorte Nisami / Influence of anemia in pregnancy on weight at birth: a coordination study / Influencia de anemia en gestantes sobre el peso al nacer: un estudio de cohorte

Este trabalho tem como objetivos avaliar a prevalência de anemia durante a gestação e sua influência em relação ao peso da criança ao nascer no município de Santo Antônio de Jesus, Bahia. Trata-se de um estudo de coorte prospectivo, realizado com gestantes cadastradas no pré-natal em 16 Unidades Básica de Saúde, de janeiro a dezembro de 2012, no município de Santo Antônio de Jesus. A amostra foi composta por 315 gestantes clinicamente saudáveis. A coleta de dados ocorreu de janeiro a junho de 2012 e utilizou questionário estruturado previamente testado como instrumento. A segunda etapa aconteceu de julho a dezembro de 2012 e compreendeu a coleta dos dados referentes ao desfecho gestacional (peso ao nascer). A digitação foi feita no programa EpiInfo 6.04 b e analisados no Stata, versão 12. A prevalência de anemia materna foi de 16,8%, com valor médio de hemoglobina de 10,1 ± 0,78g /dL. A incidência de baixo peso ao nascer foi de 4,7%, com média de 2131 g, 11 ± 526,74 g. Foi possível identificar associação positiva não significativa entre a anemia e o baixo peso ao nascer, expressa por risco relativo = 2,53 (IC95%: 0,60-10,69). A prevalência de anemia entre as gestantes avaliadas foi similiar à observada no Brasil, sendo considerada um problema de saúde moderado. Além disso, verificou-se relação positiva não significativa entre a anemia e o peso da criança ao nascer no município do estudo.

This study seeks to evaluate the prevalence of anemia during pregnancy and its influence on the weight of the child at birth in the municipality of Santo Antônio de Jesus, state of Bahia, Brazil. This is a prospective cohort study conducted with pregnant women registered for prenatal care in 16 Basic Health Units from January to December 2012, in the municipality of Santo Antônio de Jesus. The sample consisted of 315 clinically healthy pregnant women. Data was collected from January to June 2012 using a structured questionnaire previously tested as an instrument. The second stage occurred from July to December 2012 and included data collection regarding the gestational outcome (birth weight). Data were typed in the EpiInfo 6.04 b program and analyzed in STATA, version 12. The prevalence of maternal anemia was 16.8%, with a mean hemoglobin value of 10.1 ± 0.78 g/dL. The incidence of low birth weight (LBW) was 4.7% in the studied infants with a mean of 2131g, 11 ± 526.74 g. The study identified a non-significant positive association between anemia and low birth weight expressed by relative risk = 2.53 (95% CI: 0.60-10.69). The prevalence of anemia among pregnant women of the city was similar to that observed in Brazil and considered a moderate health problem. Moreover, a non-significant relationship was observed between anemia and the weight of the child at birth in the study municipality.

Este trabajo tuvo como objetivo evaluar la prevalencia de anemia durante la gestación y su influencia en relación al peso del niño al nacer en el municipio de Santo Antônio de Jesus, Bahía (Brasil). Este es un estudio prospectivo de cohorte realizado con mujeres embarazadas registradas para atención prenatal en 16 Unidades Básicas de Salud en el período de enero a diciembre de 2012, en el municipio de Santo Antônio de Jesus. La muestra fue compuesta por 315 mujeres gestantes clínicamente sanas. La recopilación de datos ocurrió de enero a junio de 2012 y utilizó un cuestionario estructurado previamente probado como instrumento. La segunda etapa ocurrió de julio a diciembre de 2012 y comprendió la recopilación de datos referentes al desenlace gestacional (peso al nacer). Para digitalizar los datos se utilizó el programa EpiInfo 6.04 b, y para analizarlos el Stata, versión 12. La prevalencia de anemia materna fue del 16,8%, con un valor promedio de hemoglobina de 10,1 ± 0,78 g/dl. La incidencia de bajo peso al nacer fue del 4,7% en los recién nacidos estudiados con promedio de 2131 g, 11 ± 526,74 g. Hubo una asociación positiva no significativa entre anemia y bajo peso al nacer, con riesgo relativo = 2,53 (IC 95%: 0,60-10,69). La prevalencia de anemia entre las gestantes evaluadas fue similar a la observada en Brasil por lo que se considera un problema de salud moderado, además se verificó una relación positiva no significativa entre la anemia y el peso del niño al nacer en el municipio del estudio.
