More than a quarter of adults aged 40 and older living in Mekelle City in northern Ethiopia carry a predicted ten-year risk of cardiovascular disease of at least 10 percent, according to a community-based cross-sectional study published in BMC Nutrition. The researchers used the updated 2020 World Health Organization cardiovascular disease risk prediction charts to estimate each participant’s risk, applying both laboratory-based and non-laboratory-based versions of the charts.
The study included 223 participants selected through systematic random sampling from the urban population of Mekelle. Participants were aged 40 years or older, and the researchers collected socio-demographic, lifestyle, anthropometric and biochemical data from each of them. More than half of the participants, 53.4 percent, were female, and the mean age was 52.8 years, with a standard deviation of 11.24 years.
The burden of underlying risk factors in the sample was substantial. Hypertension was present in 52.0 percent of participants, elevated total blood cholesterol in 44.4 percent, diabetes mellitus in 14.3 percent, and 7.6 percent reported being current smokers. These measured conditions form the core inputs of the WHO risk charts, which combine factors such as age, sex, blood pressure, cholesterol and diabetes status to estimate the probability of a cardiovascular event over the following decade.
Using linear regression, the researchers identified several characteristics significantly associated with a higher predicted ten-year risk. Male sex carried a beta coefficient of 2.22, advanced age a coefficient of 0.30, and each unit of systolic blood pressure a coefficient of 0.07, all with p values below 0.001. Diabetes mellitus showed the largest single contribution, with a beta coefficient of 5.71, while elevated total blood cholesterol contributed a coefficient of 0.02, also statistically significant.
In their conclusion, the authors reported that one-quarter of adults aged 40 years and older in the study had an elevated predicted ten-year cardiovascular disease risk of 10 percent or more, and that higher predicted risk was associated with male sex, older age, diabetes mellitus, higher systolic blood pressure and elevated total blood cholesterol.
The authors argue that these findings highlight the need to integrate WHO cardiovascular disease risk assessment into routine primary healthcare and to strengthen targeted prevention strategies, particularly for high-risk populations, in order to reduce the future burden of cardiovascular disease.
As a cross-sectional study, the work captures a single point in time and reports associations rather than causal effects. The predicted risk scores are model-based estimates of future disease probability, not observed diagnoses, and the findings apply to the sampled urban adult population of Mekelle rather than to Ethiopia as a whole.
