It found that only 0.2% of adolescents fully complied with the guidelines, and the co-occurrence of risky behaviours was common.
The primary aim was to assess adherence to the '5-2-1-0' guidelines, which promote behaviours like eating fruits/vegetables, limiting sugary drinks and screen time, and being physically active. The study found a high prevalence of overweight (12.7%) and obesity (3.2%), with girls more affected than boys. The most common combination was low fruit/vegetable consumption, insufficient physical activity, and high sugar-sweetened beverage consumption. The authors note that the cross-sectional design limits causal inference and that reliance on self-reported data introduces potential bias.
