Development and validation of a prediction model for fat mass in children and adolescents: meta-analysis using individual participant data

BMJ 2019; 366 doi: https://doi.org/10.1136/bmj.l4293 (Published 24 July 2019) Cite this as: BMJ 2019;366:l4293

All rapid responses

Rapid responses are electronic comments to the editor. They enable our users to debate issues raised in articles published on bmj.com. A rapid response is first posted online. If you need the URL (web address) of an individual response, simply click on the response headline and copy the URL from the browser window. A proportion of responses will, after editing, be published online and in the print journal as letters, which are indexed in PubMed. Rapid responses are not indexed in PubMed and they are not journal articles. The BMJ reserves the right to remove responses which are being wilfully misrepresented as published articles or when it is brought to our attention that a response spreads misinformation.

From March 2022, the word limit for rapid responses will be 600 words not including references and author details. We will no longer post responses that exceed this limit.

The word limit for letters selected from posted responses remains 300 words.

Congratulations on this progress, but in my opinion, if you wish to use this model as a preventive method you should think about its accessibility worldwide -- that is, not all populations have easy access to a computer to perform an algorithm in excel. I think it's great that they have thought about how to integrate all the variables that are not usually taken into account, such as ethnicity, as socioeconomic status influences children's diet and physical activity, which is a factor determining the generation of obesity.

Something that I think is important to highlight and should be taken into account in this type of articles is the diet and socioeconomic status of the participants. Data that provide valuable information when assessing signs related to people's nutritional status, as in this case.
