New Delhi: Kidney disorders have taken Delhiites by storm, a study conducted by the Research Wing of Maulana Azad Medical College (MAMC) has said.

The survey was conducted over 5,252 people -3,155 men and 2097 women in Delhi.

It showed that every 10th adult was affected by a kidney disorder, some sort of chronic disease. Most shocking is that even one third did not know they had a kidney problem.

In Feb 2009, the researchers submitted their report to the Bio Med Nephrology Department which showed 31.2 percent had hypertension and 7.3 percent had diabetes.

Protein in urine is a sign of kidney dysfunction - 3 percent of adult population was reported to be affected.

The study took two long years to submit its report. It was funded by the University Grants Commission (UGC). Two physicians were assigned to take blood pressure measurement at an interval of 10 minutes, dipsticks used to identify protein in urine and fasting venous blood sample was taken for the assessment of biochemical variables.

"Three important things have been identified that aggravate this disease immensely - sedentary lifestyle, bad eating habits and obesity", the researchers said.

Dr. N.P. Singh, professor, Department of Medicine, MAMC revealed, "Blood pressure measurements, blood sugar tests and urine test do not cost too much. It costs Rs.100 and keeps diseases at bay".
