1. It is not clear how the children were chosen.
Number of schools, and classes from where students were sampled also
need mention. Was any sampling technique followed?
2. Although children were categorized into
undernourished, normal and obese, the first group is nowhere
reflected in the results. Were the undernourished children included
into non-obese group? As we are facing double burden of nutrition
(under- and over-nutrition), mentioning percentage of malnourished
would be helpful in comparing both extremes of the problem.
3. Physical activity of the students and
measurement of C-reactive protein, although mentioned in
methodology, are absent in result section.
4. It is not clear why only 66 children (3.9%)
were chosen for laboratory testing whereas the prevalence of obesity
was 9.3%?
