Abstract

OBJECTIVE:

To estimate the magnitude of obesity and its relation to the 10 year probability of developing coronary artery disease (CAD) in patients attending primary health care centers (PHCCs) in Abha, southern Saudi Arabia.

SUBJECTS AND METHODS:

Saudi patients aged between 30-70 years who had attended three PHCCs in Abha city over a 6-month period (January to June 1998) and agreed to participate in the study were enrolled. All such patients had their weights and heights measured, body mass index (BMI) was calculated and they were screened for risk factors of CAD and requested to provide a fasting venous sample for lipoprotein analysis. The probability of developing coronary artery disease (PCAD) over the next ten years was calculated for each patient by means of the computer model based on Framingham heart study.2

RESULTS:

A total of 858 subjects were studied: 46% males and 54% females. The percentage of obesity was 49% and overweight 35%; Females were dominantly obese while overweight was more prevalent in males. Of the study subjects 11.5% were hypertensive with significantly higher BMI than normotensives (P=<0.001); diabetes mellitus was represented in 29.6% with no significant difference in their BMI from nondiabetics. Smokers were 4.2% and they had a significantly lower BMI than non-smokers. Individuals with high-risk threshold of TC/HDL-c ratio (≥ 5.6% for women and ≥ 6.4% for men) represented 70.48% and had significantly higher BMI than those with low risk threshold. There was no direct relationship between BMI and PCAD10 (r(2)=0.007, p<0.12).

CONCLUSION:

(1) Obesity is an epidemic health problem with an expected upward trend in Saudi Arabia similar to that of LISA and Western Europe. (2) The risk factors for CAD were highly prevalent among the PHCC patients and had a strong significant association with obesity; thus weight control should be an integral part of the prevention of CAD at PHCCs level. (3) Although obesity was found to have a significant individual association with CAD risk factors, obesity per se had no significant direct relationship with the probability of CAD at 10 years. This confirms the conclusion reached by NCEP 11 that obesity caused CAD through the associated risk factors.
