Keywords:

This observation and crossectional study aimed to examine the prevalences of Metabolic Syndrome (MetS), components and amount of metabolic risk in non-obese hypertension. Participants were 492 patients attending four rural health promotion hospitals in Nakhon Si Thammarat. Non-obese is defined as body mass index of less than 25.0 kg.m2. MetS was diagnosis based on the criteria of the American Heart Association and the National Heart Lung and Blood Institute (AHA/NHLBI). Descriptive statistic was used for prevalence. Chi-square, crude odds ratio, and 95% confident interval were used to compare the prevalences of MetS and components among normal weight and overweigt groups.
The results found 292 (59%) patients with non-obese. Prevalence rates of MetS in overall, normal weight, and overweight groups were 66%, 61%, and 76%, respectively. Mean of metabolic risk amount was 2.96±1.16, where 13% had only one risk, and 39% had at less four risk components. Over a half of them had low high-density lipoprotein (54%). Approximately a half who had hyperglycemia (48%), hypertriglyceridemia (48%) and abdominal obesity (46%). overweight group was more liklely had higher rates of MetS (OR 2.05, 95%CI 1.19-3.56), and more amount of metaboloric risk (3.35±1.21 vs. 2.77±1.08, p<0.0001), compared with normal weight. Higher rates of hyperglycemia (57% vs. 44%, OR 1.72 [95%CI 1.05-2.81]) and abdominal obesity (71% vs. 34%, OR 4.78 [95%CI 2.81-8.13]) were also found in obese or overweight compared with normal weight groups.
The prevalence of MetS in non-obese hypertension was higher than our expected, and overweight had higher odds of MetS than normal weight. Therefore, screening hypertensive patients with non-obese is very important in prevention of cardiovascular disease.
