DDI joined the global Non-Communicable Diseases Risk Factor Collaboration (NCD-RisC) consortium

Circulating cholesterol in individuals worldwide has remained constant overall since 1980 but has risen in populations from low and middleincome countries while decreasing in populations from the high-income countries. Circulating cholesterol is a risk factor for ischemic heart disease and ischemic stroke. Dietary and behavioral components influence both HDL cholesterol and non-HDL cholesterol, as do cholesterolmodifying drugs. These determinants vary worldwide.

Dr. Abdullah Alkandari and Dr. Monira AlArouj recently joined the NCD-RisC collaboration, a large group of health scientists around the world that analyse and publish epidemiological data on major risk factors for non-communicable diseases. Earlier this year, a study entitled “Repositioning of the global epicentre of non-optimal cholesterol” was published in the journal Nature3. The NCD-RisC consortium pooled 1,127 populationbased studies and analyzed the cholesterol levels of over 100 million adults in 200 countries across a 39-year time period, from 1980 to 2018. They found that high cholesterol was responsible for almost 4 million deaths around the world and half of these deaths were in East, South, and Southeast Asia. Thus, the distribution of individuals with high non-HDL cholesterol changed from populations living in high-income countries such in Western Europe to populations from low-income countries.

A second study published in the Lancet entitled “Height and body-mass index trajectories of school-aged children and adolescents from 1985 to 2019 in 200 countries: Pooled analysis of 2,182 population-based studies with 65 million participants” 4 assessed data from children aged 5 to 19 years. The study revealed that school-aged children’s height and weight, which are indicators of their health and quality of their diet, vary enormously around the world.
