Abstract
Metabolic syndrome is a cluster of metabolic abnormalities that increases the risk of cardiovascular disease and type 2 diabetes. Total human energy expenditure is divided into three major components; resting metabolic rate, thermic effect of food, and activity thermogenesis which is divided into exercise and non exercise activity thermogenesis (NEAT). In this study, NEAT was used as a lifestyle intervention on subjects with metabolic syndrome. 200 eligible patients from the Diabetes and Endocrinology Department at Hamad Medical Hospital in Doha, Qatar were assigned to an intervention (n = 100) or control (n = 100) group and followed for one year. The intervention group was advised to practice NEAT enhancing activities, while the control group was not advised about NEAT. Measurements of waist circumference, weight, BMI, blood pressure, glucose and lipid profile were assessed at baseline, six months and 1 year.After 1 year 52 intervention and 55 control subjects completed the study. The results revealed no statistically significant differences in metabolic syndrome components between the two randomized groups. The amount of recommended NEAT activity appears to have been too small to influence study outcomes. Future studies in similar populations may need to consider the high dropout rate, and use of incentives or other interventions to increase compliance and retention.

Each abnormality is associated with cardiovascular disease cases,(1) such as stroke, myocardial infarction, and heart failure.[2]. Worldwide, approximately 20 –25% of the population suffers the burden of symptoms related to metabolic syndrome.[3]. The burden is shared among the Qatari population, which suffers from high prevalence rates of obesity and type 2 diabetes.[1]. A recent study indicates that the crude prevalence of metabolic syndrome in Qatar is 34% according to the International Diabetes Federation (IDF) criteria.[2]. Risk factors associated with metabolic syndrome in the Qatari population include age, ethnicity, obesity and family history of diabetes.[2]
