Open Access Biomedical Publisher Using Post Publication Peer Review
The paper sought to estimate the prevalence of hypertension in a medically literate, young population in a South Asian country. Additionally, they wanted to study the risk factors of hypertension in this specific population. These are important study questions, considering the increasing prevalence of hypertension in South Asian countries, and the lack of good research on any of these problems.
The study does not seek to make novel claims - prevalence of hypertension and its risk factors have been studied extensively in western populations. However, the original aspect here is to study these in a specific south asian population.
This is a descriptive study, and therefore the results are descriptive in nature. However, they support the original claims in that there is a measure of prevalence of hypertension in this population, and risk factors for the same are identified.
The methodology is valid for the most part. The authors mention that the questionnaire is validated, but no description of the statistical analyses conducted to validate the questionnaire is provided. This is a caveat, as this could possibly hurt the reproducibility of the analyses.
Yes, the addition of a multivariable logistic regression model would have improved the results section. A logistic regression model prediciting hypertension would have helped identify the worst risk factors, controlling for all other predictors, and therefore pave the way for targeted interventions. Considering all data collected, this would not have been a difficult analysis to add.
No - the omission of a logistic regression model is glaring. However, it provides good insights on hypertension in a specific population. However, keeping in mind the specific population, the generalizability of the results is poor.
The role of hypertensive risk factors in youth is thevery important claim of the article
- Cardiovascular risk profile of young can increase since childhood due to different causes. Please consider also the role of childhood obesity on hypertension in adulthood. Please consider and discuss the paper from Ciccone MM et al. Eur J Cardiovasc Prev Rehabil. 2011 Dec;18(6):831-5.
- Furthermore, the role of insulin resistance, diabetes, prediabetes and family history of diabetes should be better discussed in such a context. Please consider and discuss the papers from Miniello VL et al. Int J Cardiol. 2014 Jun 15;174(2):343-7 and Ciccone MM et al. J Diabetes Metab 2014;5:364. doi: 10.4172/2155-6156.1000364.
- A multivariate regression analysis should be performed
- The use of a questionnaire is a limitation of this study and it should be discussed in a defined limitation section.

Authors have tried to determine the risk factors of hypertension among medical and dental students attending a medical college in Kathmandu. They conclude that the prevalence of hypertension and pre hypertension among the study respondents was lower than in general population in urban areas.
Overall awareness strategies and intervention programmes for those with risk factors of hypertension or other chronic NCDs is advocated.
Who validated the questionnaire? Is it tested?
How the sample size was calculated? Is it convenient sampling?
It is only with one college.
To some extent..Could have added few more.
Is there any correlation with paternal or maternal hypertension among the different study subjects?
Above concerns need to be looked into.
This study can be conducted on a larger sample size, in different colleges, different genders at different places with a neat collaboration to validate the results.
With the above limitation, this can be a pilot study.
Thepathophysiological basis for the above results claimed need further explaination.
More review of literature needed.

Studying the modifiable risk factors which can be assessed and avoided at an early stage in this age group. The study is quite significant as a preventive measure.
Not novel. However still have impact and especially done by the same target group is encouraging
The dietary component can be detailed and even the exercises can be classified to find benefit from a particular type of physical exercise.
For a preliminary study it is relevant
Done on a larger population taking into account the details from students from other faculties too.
This work can be extended further
