About this study

Official title: Effect of Yoga on Metabolic Abnormalities Outcomes in Middle-Aged and Older Adults With Metabolic Syndrome

Metabolic syndrome (MetS) is a clustering of cardiovascular risk factors characterizing central obesity, insulin resistance, dyslipidemia and high blood pressure. The concept of MetS represents the pre-cardiovascular and pre-diabetic pathologic conditions, which has been a useful tool in prognosing the development of cardiovascular disease and diabetes mellitus. Importantly, interventions applied at the pre-pathologic stage with MetS would be of great clinical and health significance in achieving better preventive and therapeutic outcomes. Yoga, a mind-body exercise, has been suggested to have beneficial effects on dyslipidemia, hypertension and diabetes. A pilot study has demonstrated the trends in the improvement of metabolic parameters in middle-aged adults with MetS but the findings are inconclusive because of the small sample size and brief yoga follow-up period (i.e., 2-month). In addition to the needs of a better designed randomized controlled trial in studying the beneficial effect of yoga in controlling MetS in middle-aged individuals, the investigation on yoga and MetS in elderly population has been lacking. This is important as the potential use of yoga as lifestyle modification in elderly individuals with MetS will result in significant reduction of the prevalence of cardiovascular disease and diabetes. Thus, this study aims to examine the efficacy of yoga exercise in improving metabolic abnormalities in middle-aged and older adults with MetS. In addition to elderly, middle-aged adults are included in the present investigation because of the idea that cardiovascular diseases and diabetes with aging can be mostly prevented by intervention at the middle-age. A randomized controlled trial with repeated measure design will be conducted to examine the effect of 1-year regular yoga training on the MetS parameters in middle-aged and older individuals who are 30-60 and 60-80 years of age, respectively. Primary outcome measures include waist circumference, systolic/diastolic blood pressure, blood glucose, triglyceride, and lipid cholesterol profile whereas secondary outcome measures include self-reported stress and depression levels. This study is anticipated to provide valuable information in exploring the therapeutic role of yoga in managing MetS. As yoga exercise is an economical regimen which can be easily and readily applied to large scale of target population, it is of hope to be practically useful to relieve the burden on cardiovascular disease and diabetes by introducing yoga lifestyle to the management of MetS.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in waist circumference

    The operational definition of waist circumference is the measure of circumference at the waist area. This is a commonly used indicator for recognizing central obesity. The waist circumference will be determined by using tape with metric scale. To determine the waist circumference, the upper hip bone will be located and a measuring tape will be placed around the abdomen. The tape measure will be horizontal and the measuring tape will not be snug but without causing compressions on the skin.

    Measured: Six Months

  2. Change in systolic/diastolic blood pressure

    Resting blood pressure measurement will be performed after the subject has taken 15-minute rest in the laboratory by using an electronic blood pressure monitor. Both the systolic and diastolic blood pressure will be obtained with the cuff over brachial artery region at the level of heart.

    Measured: Six Months

  3. Change in blood glucose

    Measurements will be performed on the glucose and insulin level in venous blood sample collected after overnight fast. Subjects will be asked to come to the laboratory after an overnight ~10 hours fasting. Before each resting blood sampling, subjects will be requested to sit in a quiet environment for 15 minutes prior to blood collection. Ten ml of venous blood will be drawn from an antecubital vein in the forearm. The blood collection will be performed by a licensed nurse or medical lab technologist. After collection of venous blood sample, blood samples will be dispensed into a lithium heparin plastic tube to prevent coagulation. The remnant whole blood will be centrifuged to obtain plasma samples and stored at -80°C in a freezer before being analyzed for glucose

    Measured: Six Months

  4. Change in triglyceride

    Ten ml of venous blood will be drawn from an antecubital vein in the forearm. The blood collection will be performed by a licensed nurse or medical lab technologist. After collection of venous blood sample, blood samples will be dispensed into a lithium heparin plastic tube to prevent coagulation. The remnant whole blood will be centrifuged to obtain plasma samples and stored at -80°C in a freezer before being analyzed for triglyceride.

    Measured: Six Months

  5. Change in lipoprotein

    The blood collection will be performed by a licensed nurse or medical lab technologist. After collection of venous blood sample, blood samples will be dispensed into a lithium heparin plastic tube to prevent coagulation. Measurements will be performed on HDL-C level in the collected venous blood samples.

    Measured: Six Months

  6. Change in waist circumference

    The operational definition of waist circumference is the measure of circumference at the waist area. This is a commonly used indicator for recognizing central obesity. The waist circumference will be determined by using tape with metric scale. To determine the waist circumference, the upper hip bone will be located and a measuring tape will be placed around the abdomen. The tape measure will be horizontal and the measuring tape will not be snug but without causing compressions on the skin.

    Measured: One year

  7. Change in systolic/diastolic pressure

    Resting blood pressure measurement will be performed after the subject has taken 15-minute rest in the laboratory by using an electronic blood pressure monitor. Both the systolic and diastolic blood pressure will be obtained with the cuff over brachial artery region at the level of heart.

    Measured: One year

After collection of venous blood sample, blood samples will be dispensed into a lithium heparin plastic tube to prevent coagulation. The remnant whole blood will be centrifuged to obtain plasma samples and stored at -80°C in a freezer before being analyzed for triglyceride.

  10. Change in lipoprotein

    The blood collection will be performed by a licensed nurse or medical lab technologist. After collection of venous blood sample, blood samples will be dispensed into a lithium heparin plastic tube to prevent coagulation. Measurements will be performed on HDL-C level in the collected venous blood samples.

    Measured: One year

Secondary outcomes (2)
  1. Change in self-reported stress and depression levels

    Self-reported stress and depression levels are proposed to be the secondary outcome measures because the stress and depression levels could be improved by yoga intervention which might have beneficial effects on MetS parameters indirectly. The indicator of stress level will be adopted to estimate the mental health in this project. The Patton Type A personality questionnaire will be used to examine the stress level. The Center for Epidemiologic Studies Depression Scale (CES-D) will be used to estimate the depression level of the subjects.

    Measured: Six Months
