Abstract

Objective: To investigate factors associated with quality of life in healthy young women with normal and overweight body mass index (BMI - kg/m2) from the short-acting contraceptive method for long-acting reversible contraceptive methods (LARC) at baseline and after 12 months of use of the new contraceptive method. Study design: A prospective cohort study with women at the CAISM Family Planning requesting an exchange from short-acting contraceptive method for long-acting reversible contraceptive method followed up for 12 months. Inclusion criteria: healthy, non-obese women aged 19-40 years with change of method for long-acting reversible contraceptives [copper intrauterine device (IUD TCu 380A), levonorgestrel releasing intrauterine system (IUS-LNG)] or etonogestrel subdermal implant. Variables: sociodemographic (age, schooling, income, marital status and number of alive children). Other variables: physical activity, body weight, BMI, body composition by densitometry, eating behavior by Three Factor eating questionnaire (TFEQ-R21), and quality of life by Medical Outcomes Study Short Form questionnaire - 36 (SF- 36). A total of 123 women will be necessary: 64 women should be included in the IUS-LNG group, 26 in the IUD TCu 380A group, and 33 in the etonogestrel subdermal implant group. An exploratory analysis of the data will be performed through the descriptive measures. To compare the categorical data, the chi-square test or, when necessary, the Fisher's exact test will be used. For the comparison of the variables evaluated at the beginning and at 12 months of the study, the analyze of variance, ANOVA, test for repeated factors will be used. The variables will be transformed to rank whether the distribution of the data not to be a normal distribution. To investigate the association between variables and components of quality of life at 12 months, the Spearman correlation test will be applied, and the non-parametric Mann Whitney test for the dichotomous variables.
