Abstract
in English, Portuguese

This article aims to examine agreement of pre-pregnancy weight, pregnancy weight, height and systolic (SBP) and diastolic (DBP) blood pressure measurements recorded on antenatal record cards with the same information obtained in the MINA-Brazil longitudinal study. 428 pregnant women who participated in the MINA-Brazil study and had an antenatal card at time of childbirth were selected. Concordance analysis of the data used Lin's correlation coefficient and Bland-Altman analysis. There was moderate agreement on self-reported pre-pregnancy weight (0.935) and height (0.913) information, and substantial agreement on the pregnant women's weight in the second (0.993) and third (0.988) trimesters of pregnancy. Little agreement was found on SBP and DBP measured in the second (SBP = 0.447; DBP = 0.409) and third (SBP = 0.436; DBP = 0.332) trimesters of pregnancy. Anthropometric measurements showed strong agreement. There was weak agreement between blood pressure measurements, which may relate both to the variability and the standardisation of these measurements, suggesting the need for continued training of antenatal teams in primary health care.

O objetivo deste artigo é analisar a concordância entre dados de peso pré-gestacional, peso na gravidez, altura e pressão arterial sistólica (PAS) e diastólica (PAD) registradas tanto na caderneta da gestante quanto nas informações obtidas no estudo longitudinal MINA-Brasil. Foram selecionadas as gestantes participantes do estudo MINA-Brasil que apresentavam cartão do pré-natal no momento do parto. A análise de concordância dos dados utilizou o coeficiente de correlação de concordância de Lin e análise de Bland-Altman. Foram incluídas 428 gestantes. Houve concordância moderada entre as informações para o peso pré-gestacional autorreferido (0,935) e altura (0,913), e concordância substancial para o peso da gestante no segundo (0,993) e terceiro (0,988) trimestres de gestação. Verificou-se baixa concordância da PAS e PAD no segundo (PAS=0,447; PAD=0,409) e terceiro (PAS=0,436; PAD=0,332) trimestres gestacionais. As medidas antropométricas apresentaram boa concordância. Houve baixa concordância entre as medidas de pressão arterial, que podem estar relacionadas tanto à variabilidade como também à padronização dessas medidas, sugerindo-se necessidade de capacitação e treinamento contínuo das equipes de pré-natal na atenção primária à saúde.
