The Association of Quality of Life and Personality Characteristics with Adolescent Metabolic Syndrome: A Cohort Study
Abstract Background: Increased prevalence of adolescent metabolic syndrome (MS) is a tracking factor for adulthood cardiovascular diseases. This study aimed to explore the potential relationship of quality of life (QoL) and personality traits with adolescent MS. Methods:1961 participants aged 11.68 years from a cohort study established in 2014 and followed in 2019 was included in Chongqing. Quality of life (QoL) and Eysenck’s personality questionnaire and MS components were collected.Results:The prevalence of adolescent MS is 4.69% (95% confidence interval, 3.84%-5.72%). Higher QoL domain score of physical activity ability (PAA) was a protective factor for both MS and MS score (all P<0.01), which was mainly negatively correlated with central obesity, diastolic blood pressure (DBP) and triglycerides levels, and positively correlated with high density lipoprotein cholesterol (HDL-C) level. Total score of QoL was negatively correlated with triglycerides level and positively correlated with DBP (all P<0.01). High extraversion personality score was a protective factor of adolescent MS (P=0.04) and MS score (P=0.06), which was mainly negatively correlated WC systolic blood pressure and TGs, and positively correlated with HDL-C (all P≤0.01).Conclusions:QoL score and extraversion personality score were independent protective factors for both MS prevalence and MS score, suggesting the community intervention to improve the QoL and psychological health of children is essential.
