A cross-sectional study examining self-reported anthropometric measurements with adolescents' nutrition attitudes, obesity awareness and diet quality indices during the pandemic.

The study included only high-school students in one district in southern Turkey, so it may not apply to other countries, ages or settings. It was cross-sectional, so it cannot show whether better nutrition attitudes, awareness or diet quality reduce body measurements, or whether measurements influence these scores. Anthropometric measurements were self-reported by adolescents using video instructions, not measured by researchers during data collection, although 100 randomly selected students were remeasured when schools reopened. Of 1058 returned forms, 151 were excluded for missing data or inaccurate measuring technique, so the analysed sample was volunteers who completed forms fully and correctly.

The study received no specific grant, and the authors declared no potential conflicts of interest.

Do not conclude that improving adolescents' nutrition attitudes, obesity awareness or Mediterranean-diet scores will lower their weight, waist or BMI measurements. This was a one-time survey using self-reported measurements, so it shows associations only.
