Introduction: Metabolic syndrome, a combination of obesity, impaired glucose tolerance, hypertension, low high-density cholesterol, and increased triglyceride levels, is now one of the most common diseases throughout the world. This study aimed to determine the effect of the husbands, social support on the control of risk factors for metabolic syndrome in women. Materials and Methods: In this clinical trial, 182 women with metabolic syndrome were systematic randomly divided into two, the experimental and the control groups. A self designed valid and reliable questionnaire on “perceived social support from husband” and a “24-hour dietary recall” questionnaire were used. Also, a data sheet used to record data on waist circumference, systolic (SBP) and diastolic blood pressure, (DBP) TG, HDL and FBS. After data collection, educational interventions were used, and 3 months after intervention, post-test results were collected. Results: Mean scores of husband social support in the experimental group was significantly higher than the control group. Also, after the intervention, significant decrease in macronutrient (fat and carbohydrate) intake was seen in the experimental group, compared to controls. Moreover, mean  waist circumference (4.2 cm), triglycerides concentration (54.15 mg/dL, fasting blood sugar, 61.13 mg/dL) SBP 7.42 mmHg and DBP 9.55 mmHg were decreased, and mean HDL increased to 5.87 mg/dL all changes were significantly greater than the control group. Conclusions: Improvement in perceived social support from husband could contribute to following a healthy diet and consequently, may reduce the risk factors of metabolic syndrome in women.
