Physical activity in gestational trimesters and perinatal outcomes in SUS puerperal women / Atividade física nos trimestres gestacionais e desfechos perinatais em puérperas do SUS

ABSTRACT OBJECTIVE Test the association between the practice of physical activity (PA) according to the gestational trimesters and the occurrence of cesarean delivery, prematurity, and low birth weight in puerperal women assisted in the Unified Health System of Santa Catarina, Brazil. METHODS A cross-sectional study was conducted with a probabilistic sample of puerperal women who gave birth in public maternity hospitals in Santa Catarina from January to August 2019. The cesarean delivery outcome was self-reported, and information on premature birth (< 37 gestational weeks) and low birth weight (< 2,500 grams) were obtained from medical records. The practice of PA during pregnancy and according to each trimester was self-reported. Multivariate Logistic Regression analyses and interviews with 3,580 puerperal women were carried out. RESULTS PA practice during any period of pregnancy was reported by 20.6% of the sample, with a gradual reduction in prevalence according to the gestational trimester (16.2%, 15.4%, and 12.8%). The highest prevalences of outcomes concerning the total sample were observed in puerperal women who did not practice PA in the third trimester, with 43.9% for cesarean delivery, 7.7% for low birth weight, and 5.5% for premature birth. The odds of cesarean delivery (OR = 1.40; 95%CI 1.10-1.76) and low birth weight (OR = 1.99; 95%CI 1.04-3.79) were, respectively, 40% and 99% higher among puerperal women who did not practice PA in the third trimester of pregnancy when compared to those who practiced PA. There was no association between PA practice and prematurity. CONCLUSION Puerperal women who did not practice PA in the third trimester of pregnancy were more likely to have cesarean delivery and low birth weight newborns.

RESUMO OBJETIVO Testar a associação entre a prática de atividade física (AF) de acordo com os trimestres gestacionais e a ocorrência de parto cesáreo, prematuridade e baixo peso ao nascer em puérperas atendidas no Sistema Único de Saúde de Santa Catarina, Brasil. MÉTODOS Estudo transversal realizado com amostra probabilística de puérperas que tiveram seus partos em maternidades da rede pública de Santa Catarina no período de janeiro a agosto de 2019. O desfecho parto cesáreo foi autorreferido e as informações sobre parto prematuro (< 37 semanas gestacionais) e baixo peso ao nascer (< 2.500 gramas) foram obtidas dos prontuários. A prática de AF durante a gestação e conforme cada trimestre foi autorreferida. Foram realizadas análises de Regressão Logística Multivariável e entrevistas com 3.580 puérperas. RESULTADOS A prática de AF durante qualquer período da gestação foi relatada por 20,6% da amostra, com redução gradativa das prevalências conforme os trimestres gestacionais (16,2%, 15,4% e 12,8%). As maiores prevalências dos desfechos em relação à amostra total, foram observadas nas puérperas não praticantes de AF no terceiro trimestre, sendo 43,9% para o parto cesáreo, 7,7% para o baixo peso ao nascer e 5,5% para o parto prematuro. As chances de parto cesáreo (OR = 1,40; IC95% 1,10-1,76) e de baixo peso ao nascer (OR = 1,99; IC95% 1,04-3,79) foram, respectivamente, 40% e 99% maiores entre as puérperas que não praticaram AF no terceiro trimestre da gestação quando comparadas àquelas que praticaram AF. Não houve associação da prática de AF com a prematuridade. CONCLUSÃO As puérperas que não praticavam AF no terceiro trimestre da gestação tiveram maiores chances de parto cesáreo e de terem recém-nascidos com baixo peso.

Association between excessive maternal weight, periodontitis during the third trimester of pregnancy, and infants' health at birth

Abstract Excessive weight is associated with periodontitis because of inflammatory mediators secreted by the adipose tissue. Periodontal impairments can occur during pregnancy due to association between high hormonal levels and inadequate oral hygiene. Moreover, periodontitis and excessive weight during pregnancy can negatively affect an infant's weight at birth. Objective This observational, cross-sectional study aimed to evaluate the association between pre-pregnancy overweight/obesity, periodontitis during the third trimester of pregnancy, and the infants' birth weight. Methodology The sample set was divided into 2 groups according to the preconception body mass index: obesity/overweight (G1=50) and normal weight (G2=50). Educational level, monthly household income, and systemic impairments during pregnancy were assessed. Pocket probing depth (PPD) and clinical attachment level (CAL) were obtained to analyze periodontitis. The children's birth weight was classified as low (<2.5 kg), insufficient (2.5-2.999 kg), normal (3-3.999 kg), or excessive (≥4 kg). Bivariate analysis (Mann-Whitney U test, t-test, chi-squared test) and logistic regression (stepwise backward likelihood ratio) were performed (p<0.05). Results G1 showed lower socioeconomic levels and higher prevalence of arterial hypertension and gestational diabetes mellitus during pregnancy than G2 (p=0.002). G1 showed higher means of PPD and CAL (p=0.041 and p=0.039, respectively) and therefore a higher prevalence of periodontitis than G2 (p=0.0003). G1 showed lower infants' birth weight than G2 (p=0.0004). Excessive maternal weight and educational levels were independent variables associated with periodontitis during the third trimester of pregnancy (X2[2]=23.21; p<0.0001). Maternal overweight/obesity was also associated with low/insufficient birth weight (X2[1]=7.01; p=0.008). Conclusion The present findings suggest an association between excessive pre-pregnancy weight, maternal periodontitis, and low/insufficient birth weight.

Association between periodontal condition and subgingival microbiota in women during pregnancy: a longitudinal study

Objectivo In this study, the gingival conditions and the quantitative detection for Aggregatibacter actinomycetemcomitans, Fusobacterium nucleatum, Porphyromonas gingivalis and Prevotella intermedia in pregnant women were determined. Material and Methods Quantitative determinations of periodontal bacteria by using a SyBr green system in women during pregnancy were performed. Women at the 2nd and 3rd trimesters of pregnancy and non-pregnant women were included in this study. A. actinomycetemcomitans was observed in high numbers in women at the 2nd and 3rd trimesters of pregnancy with a significant difference (p<0.05). F. nucleatum and P. intermedia were also observed in high levels. Results and Conclusion Our results show that pregnant women are more susceptible to gingivitis, and the presence of A. actinomycetemcomitans in subgingival biofilm might be taken into account for the treatment of periodontal disease. .
