Phase angle and body composition: an observational study of women using oral contraceptives/ANGULO DE FASE E COMPOSICAO CORPORAL: ESTUDO OBSERVACIONAL DE MULHERES EM USO DE CONTRACEPTIVOS ORAIS

Introduction and objective: Contraceptive methods aim to prevent pregnancy, and hormonal methods promote fewer changes in the levels of progesterone and estrogen during the months. This study aims to evaluate the body composition of women using hormonal contraceptives in comparison with a control group not using hormonal contraceptives. Materials and methods: This was a cross-sectional study conducted at the Nutrition School Clinic, Midwestern State University, with women between 18 and 59 years of age, evaluated by weight, height, body mass index, waist circumference, and electrical bioimpedance analysis. Results: Seventy-two women participated in the study, divided into the "no oral contraceptive" group with 48.6% (n=35) and the "oral contraceptive" group with 51.4% (n=37) of the sample. The mean age was 30.5 years, with no difference between the groups (p=0.167). The mean weight in the oral contraceptive group was 70.05 kg and 68.53 kg in the no contraceptive group. Women using oral contraceptives had a higher body mass index classified as overweight, 64.9% (n=24). Women using oral contraceptives had higher numerical values for body fat percentage and lower values for phase angle. Discussion: The use of oral contraceptives seems to affect the nutritional status of women, in addition to predisposing them to other risks already documented in the literature. Conclusion: The data suggest that the group of women who did not use hormonal contraceptives had a better classification of nutritional status compared to those who did. Key words: Contraceptives.

Introducao e objetivo: metodos contraceptivos visam impedir a gestacao, em que os do tipo hormonal promovem menores alteracoes nos niveis de progesterona e estrogenio durante os meses. O objetivo deste estudo e avaliar a composicao corporal de mulheres que estejam em uso de contraceptivos hormonais, comparadas a um grupo controle que nao utiliza. Materiais e metodos: Estudo de carater transversal realizada na Clinica Escola de Nutricao, da Universidade Estadual do Centro-Oeste, com mulheres entre 18 e 59 anos, avaliadas por meio do peso, estatura, indice de massa corporal, circunferencia da cintura, e analise por bioimpedancia eletrica. Resultados: Participaram do estudo 72 mulheres separadas em grupos "nenhum contraceptivo oral" com 48,6% (n=35), e "grupo contraceptivo oral" compondo 51,4% (n=37) da amostra. A media de idade fo
