It has come to the authors’ attention that a minority of participants were assigned an incorrect Extended International Obesity Task Force (IOTF) grade for their Body Mass Index (BMI). The misclassification concerns a minority of cases (approximately 2% of the sample) and is limited to only a subset of female participants aged 11–17 years old.

The findings, conclusions, and interpretations of the paper are unchanged, but corrections to the text and tables of the above published article are presented below:

For example, those reporting medium marketing awareness were 1·5 times more likely to report higher weekly consumption of cakes/biscuits compared with those reporting low awareness (AOR = 1·51, P = 0·012).

Correction

For example, those reporting medium marketing awareness were 1·5 times more likely to report higher weekly consumption of cakes/biscuits compared with those reporting low awareness (AOR = 1·49, P = 0·014).

A survey weight (based on age, gender, ethnicity, region and social grade) enabled descriptive data to be representative of the UK population.

A survey weight (based on age, gender, ethnicity, region, and area level of deprivation) enabled descriptive data to be representative of the UK population.

Original text (page 2638, Measures)

Participants self-reported their height (options presented in both feet and inches or centimetres) and weight (options presented in stones and pounds, kilograms or pounds only).

Correction

Participants self-reported their height (options presented in both feet and inches or centimetres) and weight (options presented in stones and pounds, kilograms or pounds only). This information was reported by participants aged 16-19 years and parent(s)/guardian(s) for 11-15 year olds.

Original text (page 2642, Sample Characteristics)

After excluding participants with missing data for height or weight (n 816, weighted), 61·5 % were categorised as healthy weight, 17·3 % underweight, 16·2 % overweight and 5·0 % obese.

Correction

After excluding participants with missing data for height or weight (n 816, weighted), 61.9% were categorised as healthy weight, 18.0% underweight, 15.3% overweight and 4.8% obese.

For example, those reporting medium marketing awareness were 1·51 times (95 % CI 1·10, 2·08) more likely to report higher weekly consumption of cakes/biscuits v. low awareness, whereas those reporting high awareness were 1·77 times more likely (95 % CI 1·33, 2·36) v. low and medium awareness combined

Correction

For example, those reporting medium marketing awareness were 1·49 times (95 % CI 1·08, 2·06) more likely to report higher weekly consumption of cakes/biscuits v. low awareness, whereas those reporting high awareness were 1·78 times more likely (95 % CI 1·33, 2·37) v. low and medium awareness combined

Original text (page 2642, Marketing awareness and weekly consumption of foods high in fat, salt or sugar)

Consistent with the first group, the likelihood of higher weekly consumption increased relative to marketing awareness. For example, those reporting medium marketing awareness were 1·46 times (95 % CI: 1·02, 2·08) more likely to report higher weekly consumption of takeaways v. low awareness, while those reporting high awareness were 2·16 times (95 % CI 1·62, 2·86) more likely v. low and medium combined

Correction

Consistent with the first group, the likelihood of higher weekly consumption increased relative to marketing awareness. For example, those reporting medium marketing awareness were 1·45 times (95 % CI: 1·02, 2·07) more likely to report higher weekly consumption of takeaways v. low awareness, while those reporting high awareness were 2·16 times (95 % CI 1·62, 2·87) more likely v. low and medium combined

Original text (page 2643, Marketing awareness and weekly consumption of healthy foods)

There was an association between awareness of marketing for HFSS foods and higher weekly consumption of diet/sugar-free drinks (HFSS alternative) – with those reporting high marketing awareness being 1·7 times (95 % CI 1·28, –2·26) more likely to report high weekly consumption of diet/sugar-free drinks than those reporting medium or low awareness.

Correction

There was an association between awareness of marketing for HFSS foods and higher weekly consumption of diet/sugar-free drinks (HFSS alternative) – with those reporting high marketing awareness being 1·68 times (95 % CI 1·27, –2·23) more likely to report high weekly consumption of diet/sugar-free drinks than those reporting medium or low awareness.
