RESUMO

Objective: To evaluate the eating behavior and nutritional status of adolescents with fibromyalgia; relating their eating behavior to socio-economic, anthropometric and other variables related to the illness. Methods: In a cross sectional, prospective and controlled study, the following data were evaluated in 23 adolescents with fibromyalgia, paired with a healthy control group (n=23): BMI and height to age z scores (OMS, 2005, 2007), waist circumference 2, body composition for bioelectric impedance analysis 6 (Mc Carthy, 2006), food intake (NutWin/Unifesp) and eating behavior and body image (questionnaire KEDS-Kids Eating Disorders Survey). Statistical analysis: chi-square, Mann-Whitney test and Spearman correlation. A significance level of p<0.05 was adopted. Results: Median of the two age groups was 15 years and the socio-economic level most widely encountered was B2. For the fibromyalgia group, it was verified that: the median of the time for illness diagnosis was 13.5 months, the number of painful points on the starting date of the study was 10.0 and that 26% made use of amitriptiline. In relation to the classification of nutritional condition via BMI z score, abdominal circumference, and body composition by BIA, no significant difference was observed between the groups, nor in relation to energy food consumption and macro and micro nutrients. In relation to a concern about excessive weight, body image, dissatisfaction with body image and final KEDS score, there was also no significant statistical difference between the fibromyalgia and control groups. For the adolescents with fibromyalgia the KEDS association and fat mass were stronger and statistically significant (r=0.713; p<0.001). By using the median final KEDS score of the control group (4) for stratifying the group with fibromyalgia and to evaluate which variables were associated to a higher KEDS score (>4), it was verified that only overweight and obesity (BMI z score) showed an association. Conclusions: The adolescents with fibromyalgia did not demonstrate alterations in their nutritional status, in eating behavior and in body image when compared with an healthy control group. Taking into consideration the association, in adults, of fibromyalgia to obesity, eating disorders, metabolic syndrome and a worsening in their quality of life, the importance of nutritional guidance and of life style while still in the adolescent age group was emphasized.
