Evaluation of food habits and physical activity in Galician students

Abstract

Introduction: obesity causes millions of deaths each year. Its high prevalence in children and adolescents from southern European countries, including Spain, is associated with the new food preferences and decreased physical activity. Objective: to evaluate diet quality and physical activity in Galician schoolchildren in order to assess if modifying the current intervention strategies in lifestyles is required. Methods: in the present study, 662 students from the south of Galicia were studied (9-17 years). Body mass index (BMI) was calculated as adiposity indicator. The dietary pattern was evaluated through the Kidmed test and physical activity with PAQ-C. The sample was stratified by BMI according to Cole international standards. Data were analysed with the SPPS software. Results: fifty-six per cent of children are at high risk of overnutrition or need to improve their nutrition. The average adherence to the Mediterranean diet was low (7.64 ± 2.28), worsening with age and adiposity significantly. The average level of physical activity was moderate (3.02 ± 0.74) and it was lower in girls and adolescents; 58% showed a low-moderate level of physical activity. Quality diet was positively correlated with physical activity and negatively with BMI. Conclusions: Galician students showed a diet and physical activity risky pattern according to international/national recommendations. After several years of awareness campaigns and lifestyle interventions, improving their diet and increasing physical activity is still necessary.
