Sir,

I have read a recent publication entitled "an epidemiological study of metabolic syndrome (MS) in a rural area of Ambala District, Haryana", and would like to comment on certain issues. [1] The prevalence of MS as found in the study was 9.2%. MS is a cluster of cardiovascular risk factors. Although there are various definitions of MS, its common pathophysiology is insulin resistance, and a prominent clinical feature of the syndrome is abdominal or central obesity. [2]

In a study conducted by Pathania et al., the definition used was the clinical definition given by the International Diabetes Federation (IDF). [3] It includes central obesity (waist circumference 90 cm in men and 80 cm in women) plus any two of the following four factors (i.e. raised triglycerides level: ≥150 mg/dl or a specific treatment for this lipid abnormality, reduced high-density lipoprotein cholesterol: <40 mg/dl in males and < 50 mg/dl or a specific treatment for this lipid abnormality, raised blood pressure [BP]: Systolic BP ≥ 130 or diastolic BP ≥ 85 mm Hg or treatment for previously diagnosed hypertension, raised fasting plasma glucose ≥ 100 mg/dl [5.6 mmol/L] or previously diagnosed type 2 diabetes).

The authors indicated a significantly higher prevalence of MS with higher education. This is a valid finding as it indicates more premorbid status in individuals of higher social status. However, documenting an association of MS with hypertension, waist circumference and fasting glucose level is unprofitable, as the definition used for MS is inclusive of these parameters. The information regarding the association of MS with risk factors such as sociodemographic parameters, dietary habits, physical activity, personal habits, and other parameters of obesity could have been of immense help in improving the knowledge of readers.

The authors indicated that the WHO STEPS approach was used to collect the data. STEPS methodology mentions a specific technique for calculating sample size by taking into consideration 10-year-age groups, gender, design effect, etc. [4] Therefore, the sample size calculated and surveyed in the study would not have been adequate to reach a valid scientific conclusion. I suggest that this should be mentioned as a limitation of the study and readers cautioned to interpret these findings with this in mind.
