Insatisfação corporal e qualidade de vida durante a menarca e sua relação com a renda familiar e o índice de massa corporal: Um estudo longitudinal

Abstract

This study analysed the association between family income and body mass index levels with body image and quality of life along the menarche; and the variation of the relation between family income and BMI with body image and life quality at different moments of the menarche (moments 1, 2 and 3). The study was characterized by a longitudinal delimitation involving teenagers aged 10 to 13, BMI 18.98 kg/m2 . The data was collected through the Body Shape Questionnaire and Autoquestionnaire Qualité de Vie Enfant Image at moment 1 in 2010, at moment 2 in 2011 and at moment 3 in 2012. The main results showed BMI positively related to the total score of body dissatisfaction in moments 1, 2 and 3; analysis on family income levels and BMI showed positive improvements along the menarche; and life quality score raised from moment 1 to 2, having decreased from moment 2 to 3. The conclusion was that adolescents showed lower dissatisfaction with body image as time went by, enhanced by a normal BMI; and as time went by the low body image dissatisfaction came out by the positive association between family income and BMI. Quality of life was better between moments 1 and 2 of the menarche, but there was a decrease in the life quality of the adolescents.
