    First I would thank Wu J et al, for publishing their research on prevalence of hypertension & its associated risk factors in your esteemed journal and this work is of high public health priority. There is no mention on the study setting where the blood pressure was actually measured, as the variability can be expected in settings like clinic where there is a chance of white coat hypertension which might not be there if measured at home by the health worker. Though the variability in blood pressure would be taken care by taking average of three readings, maintaining uniformity in study setting would offer high internal validity. In the methodology section, there is no mention on exclusion criteria and if pregnant women were included into the study as they are of different risk profile. Behavioral factors like smoking/alcohol intake were captured through face to face interview; hence social desirability can play a role in the risk factor ascertainment.
