Fraqueza muscular ao longo da gravidez e pós-parto entre gestantes adolescentes e adultas

Abstract

Abstract: Maternity in adolescence has been identified as a public health problem for several decades, and studies have associated teenage pregnancy with worse results in physical performance. Objectives: To evaluate and compare the occurrence of handgrip muscle weakness and hip adduction in adolescent and adult pregnant women throughout pregnancy and postpartum. Methods: This is an observational, prospective cohort study conducted between July 2017 and January 2019 with women living in Rio Grande do Norte, in the region of Trairi. Adolescents (13 - 18 years old) and adults (23 - 28 years old), pregnant for the first time, who did not exceed the 16th week of pregnancy and without previous diagnosis of chronic conditions were included. The collection took place in 3 different moments (until the 16th week of gestation, in the third trimester and, between the 4th and 6th week postpartum) and the handgrip strength (muscle weakness present if ≤ 20.67Kgf) and adductors were evaluated. hip (muscle weakness present if ≤ 13.8 kg). To assess the association between muscle weakness and age groups, the chi-square test was used. Results: There was no significant difference for handgrip strength results between age groups. There was a significant difference in the third trimester for the strength of hip adductors in adolescents compared to adults, respectively (62.5% vs 31.8%, p <0.005). Conclusion: There is a greater proportion of pregnant adolescents with muscle weakness, which reinforces the need for the elaboration, validation and inclusion of rehabilitation programs, and of a preventive nature.
