Health-related quality of life in adolescents with excess weight.

OBJECTIVE

To identify health-related quality of life in adolescents with excess weight and associated factors, such as gender, age, and weight categories.

METHOD

A cross-sectional study with collected and secondary data from 276 adolescents aged between 10 and 19 years with overweight and obesity, and whose parents or guardians authorized their participation. Anthropometric data, pubertal development, and the PedsQL 4.0 questionnaire were collected for the health-related quality of life assessment. Categorical data were described as numbers and percentages. For the description of health-related quality of life subscales, medians and the 25 and 75 percentiles were used, as well as the Mann-Whitney test for comparisons between age group, gender, and weight categories.

RESULTS

The median health-related quality of life total score was 78.3 (68.5-87.4). The lowest scale was the "emotional score", 65 (50-80). Higher health-related quality of life was found in boys in most of the scores (p<0.05), except for the "school score" (p=0.09). Regarding the age group, the median of the "physical scores" (p=0.03) and "social score" (p=0.02) were significantly lower in the group younger than 14 years. When separated according to weight categories, it was verified that obese adolescents differed significantly in relation to the "physical score" (p=0.00), "school score" (p=0.04), and "total score" (p=0.02) of the health-related quality of life. However, there was no significant difference between the emotional, social, and psychosocial scores.

CONCLUSIONS

Adolescents with overweight and obesity show losses in the health-related quality of life and also between the different domains, when separated by age, gender, and weight categories.
