nationally representative data

Reviewer's report:
There are points in the article that need to be corrected. Some points also need
explanation.
1- In the results section, reference is made to Table 3 where reference should be
made to Table 2.
2- The p values given in the tables as 0.000 should be corrected as p <0.001.
3- Only percentages are given in Table 2. It would be appropriate to give
frequencies together with percentages.
4- In the "Determinants of malnutrition" title in the results section, it was
mentioned that two separate models were created for undernutrition and
overweight / obesity. It is understood from this statement that two separate
binary logistic regressions were performed, taking the normal group as a
reference category. If so, how was univariate analysis with 3 groups used in
choosing the variables to be included in regression analysis? Undernutrition,
normal and overweight / obesity are ordinal variable. Why was ordinal
regression not used in the analysis?
5- Although some variables found to be significant do not have a clinically
significant difference, it is thought that there is a significant difference due to the
size of the sample size (eg household size).
6- In Table 3, mothers' primary school education protects against malnutrition,
while secondary school education has no effect. Also, mothers' primary school
education is a risk factor for obesity, while there is no significance for secondary
school. Why mothers' secondary school education doesn't protect against
malnutrition and isn't a risk factor for obesity should be explained.
