Conditions

Outcome Measures

Primary Outcomes (2)

  • the improvement of suboptimal health status

    The improvement of suboptimal health status is evaluated by the change of the SHSQ-25 scores after intervention.

    three months

  • the improvement of traditional cardiovascular risk factors

    To investigate the changes of traditional cardiovascular risk factors such as blood pressure, lipids, fasting plasma glucose, and body mass index with three months supplementation of omega-3 fatty acids. Abnormal cardiovascular risk factors are defined according to the Adult Treatment Panel III criteria for metabolic syndromes and the recommendation by the Working Group on Obesity in China. The number of abnormal cardiovascular risk factors for each participant is recorded before and after intervention. If the number decreases after intervention, it means that the traditional cardiovascular risk factors have been improved.

    three months

Study Arms (2)

Omega-3 fatty acid capsules

EXPERIMENTAL

Omega-3 fatty acid capsules, 4 g/day, requiring intake 2 capsules (1g each one) in the morning and two at night for 3 months.

Dietary Supplement: Omega -3 fatty acids

PLACEBO COMPARATOR

Corn oil in similar presentation as omega-3 fatty acid capsules, requiring intake 2 capsules in the morning and two at night for 3 months.

Dietary Supplement: Placebo: Corn oil

Interventions
