DELGADO-FLOODY, Pedro et al. The social and psychological health of children is associated with Mediterranean diet adherence items, cardiorespiratory fitness, and lifestyle. Nutr. Hosp. [online]. 2021, vol.38, n.5, pp.954-960.  Epub Jan 24, 2022. ISSN 1699-5198.


Mediterranean diet (MD) adherence, physical activity (PA) patterns, and physical fitness are associated with physical, social, and psychological health in children.


the purpose of this study was to determine the association of items of MD adherence, fitness components, and lifestyle with psychological and social health in Chilean schoolchildren.

Material and methods:

this cross-sectional study included 615 schoolchildren, both girls (n = 271, 11.7 ± 1.00 years old) and boys (n = 344, 11.8 ± 1.1 years old). Anthropometric parameters, fitness components, lifestyle, health-related quality of life (HRQoL), and self-esteem were measured.


HRQoL showed an association with cardiorespiratory fitness (β: 0.12, p < 0.001) and PA (β: 0.32, p = 0.023). Self-esteem was inversely associated with screen time (β: -1.35, p < 0.001). Moreover, social health presented a positive association with PA after school (β: 0.06, p = 0.037). In relation to MD adherence items, HRQoL was linked to the items “Takes a fruit or fruit juice every day” (β: 1.93, p = 0.004) and “Consumes fresh or cooked vegetables > 1 time/day” (β: 1.12, p = 0.018). Self-esteem was associated to “Consumes a dairy product > 1 time/day” (β: 3.30, p = 0.030). Social health was inversely related to “Eats at a fast food restaurant ≥ 1 time/week” (β: -0.26, p = 0.003) and positively to “Consumes pasta or rice almost every day” (β: 0.35, p = 0.049).


MD adherence items, fitness, and lifestyle were linked to psychological and social health, therefore it is necessary to develop preventive strategies for schoolchildren to change in a positive way these modifiable lifestyle behaviors.
