Healthians, a diagnostics company, surveyed over 250 Indian cities. The survey revealed that 6 in every 10 Indians had abnormal levels of bad cholesterol, with the highest prevalence among the 31–40-year age group. The survey conducted by the firm anonymized the data collected from 2.66 million people in the age group of 20 years and older and revealed that 63% had high low-density lipoprotein (LDL) cholesterol levels in their blood.

Mr. Deepak Sahni, Founder & CEO of Healthians, stated that in the 31–40-year group, 69% of the patients tested had abnormal levels of LDL. He added that this could be an indication of high-stress levels in that age group.

This, according to doctors, is the cause of the recent increase in cardiac arrests. She added that, as per the survey, 3 in every 10 Indians have abnormal levels of total cholesterol in their bloodstream, with the highest prevalence amongst the 31–40 age group.

The survey results also showed that 36% of Indians in the 40–60 age range have abnormal levels of total cholesterol. Interestingly, those who are older had lower levels of total cholesterol. The corresponding percentage was 30% in the 60-70 age group, while it was 24% in the 70-80 age group.

When the data were analyzed based on the gender criteria, it was found that males had a higher prevalence of abnormal levels of LDL, triglycerides, and total cholesterol. About 64% of the males tested had abnormal LDL, 47% had abnormal triglycerides, and 32% had abnormal total cholesterol compared to 63%, 30%, and 29% in females, respectively. However, more females had abnormal HDL levels compared to males.
