O gasto energético (GE) na gestação é fundamental no aconselhamento dietético e no controle da massa corporal. O presente estudo teve como objetivo realizar revisão sistemática nas bases de dados bibliográficas sobre a taxa metabólica basal (TMB), maior componente do GE, durante a gestação de feto único de mulheres saudáveis. Segundo os critérios de inclusão, 37 artigos foram selecionados (24 estudos de coorte e 13 seccionais). O aumento da TMB (entre 8,0 e 35,0%) ocorreu na maioria de estudos de coorte dependendo do tempo de seguimento e do estado nutricional. Nos seccionais, o aumento na TMB foi de 8,0-28,0% na fase final da gestação sobre a fase inicial ou no pós-parto. Informação precária sobre idade materna, perdas de seguimento e curto tempo de acompanhamento durante a gestação foram limitações dos estudos revisados. Em conclusão, a TMB aumenta durante a gestação e o aumento é mais intenso a partir do 2º trimestre. As estimativas mais confiáveis provêm dos poucos estudos de coorte iniciados na fase pré-gestacional.
Gestational energy expenditure (EE) is the basis for nutritional counseling and weight control. The objective of the present study was to systematically review the behavior of the basal metabolic rate (BMR), the largest component of EE, during non gemelar pregnancy of healthy women. Based on the inclusion criteria 37 articles were identified (24 cohort and 13 cross-sectional studies). Increases in BMR (between 8.0 and 35.0%) were observed in most cohort studies and it was related to the duration of follow-up and nutritional status. In the cross-sectionals, the increase in BMR varied from 8.0 to 28.0% close to delivery comparatively to the first trimester or post-partum. Lack of information on maternal age, loss of follow-up and short duration of follow-up during the pregnancy were serious limitations in the identified studies. In conclusion, BMR increases during pregnancy, particularly after the second trimester. The best reliable data come from the few cohort studies that initiated before pregnancy.
