Erratum - Association between Dietary Glycemic Index and Excess Weight in Pregnant Women in the First Trimester of Pregnancy.

Objective To assess the association between dietary glycemic index (GI) and excess weight in pregnant women in the first trimester of pregnancy. Methods A cross-sectional study in a sample of 217 pregnant women was conducted at the maternal-fetal outpatient clinic of the Hospital Geral de Fortaleza, Fortaleza, state of Ceara, Brazil, for routine ultrasound examinations in the period between 11 and 13 weeks+6 days of gestation. Weight and height were measured and the gestational body mass index (BMI) was calculated. The women were questioned about their usual body weight prior to the gestation, considering the prepregnancy weight. The dietary GI and the glycemic load (GL) of their diets were calculated and split into tertiles. Analysis of variance (ANOVA) or Kruskal-Walls and chi-squared ( (2) ) statistical tests were employed. A crude logistic regression model and a model adjusted for confounding variables known to influence biological outcomes were constructed. A p -value<0.05 was considered significant for all tests employed. Results The sample group presented a high percentage of prepregnancy and gestational overweight (39.7% and 40.1%, respectively). In the tertile with the higher GI value, there was a lower dietary intake of total fibers ( p =0.005) and of soluble fibers ( p =0.008). In the third tertile, the dietary GI was associated with overweight in pregnant women in the first trimester of gestation, both in the crude model and in the model adjusted for age, total energy intake, and saturated fatty acids. However, this association was not observed in relation to the GL. Conclusion A high dietary GI was associated with excess weight in women in the first trimester of pregnancy. Resumo Objetivo Avaliar a associacAo entre indice glicemico (IG) dietetico e presenca de excesso de peso em gestantes no primeiro trimestre de gestacAo. Metodos Estudo transversal realizado com 217 gestantes atendidas no Ambulatorio de Medicina Materno-Fetal do Hospital Geral de Fortaleza, Fortaleza, CE, para realizacAo de exames ultrassonograficos de rotina no periodo entre 11 e 13 semanas e 6 dias de gestacAo. Peso e altura foram obtidos para o calculo do indice de massa corporal (IMC) gestacional. As mulheres foram questionadas quanto ao peso corporal habitual anterior a gestacAo, considerado o peso pre-gestacional. O IG e a carga glicemica (CG) das suas dietas foram calculados e divididos em tercis. As associacoes foram investigadas por analise de variancia (ANOVA, na sigla em ingles) ou pelos testes Kruskal-Walls e qui-quadrado ( (2) ). Resultados O grupo tinha alto percentual de excesso de peso pre-gestacional (39,7%) e gestacional (40,1%). Houve menor consumo de fibras totais ( p =0,005) e fibras insoluveis ( p =0,008) no tercil de maior valor de IG. No terceiro tercil, o IG da dieta foi associado ao excesso de peso das mulheres no primeiro trimestre de gestacAo, tanto no modelo bruto como no modelo ajustado para idade, consumo total de energia e de acidos graxos saturados. No entanto, nAo se observou esta associacAo em relacAo a CG. ConclusAo O alto IG da dieta consumida foi associado ao excesso de peso das mulheres no primeiro trimestre da gestacAo.
