摘要

Background

Obesity is an important determinant of mental health in the child and adolescent population. In this study, the association between obesity and the development of psychological problems in Spanish children aged 9 and 12 years was examined.

Methods

In this prospective study, 2,473 9-year-old children and 2,119 12-year-olds who participated in the Longitudinal Study of Childhood Obesity (ELOIN) were evaluated. The standardized BMI was calculated from weight and height, and weight status was classified according to the 2007 World Health Organization criteria. Mental health difficulties were assessed using the Strengths and Difficulties Questionnaire (SDQ), which was completed by the parents. BMI and SDQ scores were determined repeatedly at 9 and 12 years of age. Using generalized estimating equations, β coefficients were calculated when analysing the SDQ scores, and odds ratios (ORs) were calculated to estimate mental health risk using Goodman´s British cut-off points.

Results

Compared with participants without obesity, those who had obesity had a higher total score on the SDQ (β coefficient: 1.12 (95% CI: 0.59; 1.64)) and an increased risk of mental health risk (OR: 1.36 (95% CI: 1.09; 1.69)). ORs of 1.48 (95% CI: 1.21; 1.81) for emotional problems, 1.40 (95% CI: 1.15; 1.70) for conduct problems, and 2.25 (95% CI: 1.83; 2.77) for problems with peers were estimated. This association of weight status with mental health difficulties was moderately greater in girls than in boys, although the difference was not statistically significant.

Conclusions

Childhood obesity was associated with mental health difficulties, especially emotional symptoms, behavioural problems and relationships with peers. Identifying and responding to these psychological problems should also be an objective in public health policies and procedures for controlling obesity in children.
