Prevalence of metabolic syndrome and the association with socio-demographic characteristics and physical activity in urban population of Iranian adults: A population-based study

BackgroundThe metabolic syndrome (MetS) is the main concern of health problem in transition population. The objective was to determine the prevalence of MetS and its association with socio-demographic and physical activity in Iranian adults.MethodsA population-based cross-sectional study of 1000 representative samples aged 20–70 years was conducted in urban area in northern Iran. The socio-demographic data were collected by interview and the physical activity was assessed by standard International Physical Activity Questionnaire (IPAQ). Weight, height, waist circumference and the systolic and diastolic blood pressures were measured by standard methods. Fasting plasma glucose, triglycerides, total cholesterol, high density lipoprotein-cholesterol level and low density lipoprotein cholesterol level were measured using enzymatic method. The ATP III criteria were used for diagnosis of MetS.ResultsThe prevalence rate of MetS was 42.3% (36.5% men and 47.1% women, p = 0.001). The higher education at university level was appeared inversely associated with MetS (age adjusted OR = 0.34, p = 0.001) compared with illiterate. The prevalence rates of MetS were 49.0%, 42.5% and 22.6% in low, moderate and vigorous physical activity level respectively (p = 0.001). After adjusting for potential confounding factors, the vigorous physical activity was inversely associated with MetS compared with low level (adjusted OR = 0.46, p = 0.001).ConclusionThese results highlight an immediate action of preventive measures programs for modification of cardio metabolic risk factors.
