Key result
In a Korean population with metabolic syndrome, walking exercise was independently associated with better mobility (OR 0.635; 95% CI 0.439-0.919) and self-care compared to non-exercisers.

Does exercise (resistance, flexibility, walking) improve quality of life in a Korean metabolic syndrome population?
Walking exercise is independently associated with better mobility and self-care quality of life subsets in patients with metabolic syndrome.
BACKGROUND: Metabolic syndrome (MetS) significantly correlates with exercise. MetS also has an independent and inverse correlation to quality of life (QoL). However, few studies have examined the association between exercise and QoL in people with MetS. The aim of this study was to ascertain the relationship between exercise and QoL in a MetS population. METHODS: This was a cross-sectional study using public data from the Sixth Korean National Health and Nutrition Examination Survey in 2014 (n = 7550). MetS was defined on the basis of the revised National Cholesterol Education Program criteria. Demographic factors, three types of exercise (resistance, flexibility, walking), five subsets of EuroQoL (mobility, self-care, usual activities, pain/discomfort, anxiety/depression), and QoL scores (EQ-VAS), were investigated. Independent associations of each exercise on five subsets of QoL were determined using odds ratios (OR) adjusted for four demographic factors (age group, sex, weight change, and area of residence) using multivariate logistic regression analysis. RESULTS: Prevalence of MetS was 26.4% and the ratio of subjects performing resistance, flexibility, or walking exercise was 17.7%, 45.8%, and 71.5% among this population, respectively. EQ-VAS of exercisers was significantly higher than that of non-exercisers in resistance, flexibility, and walking exercise. Although resistance and flexibility exercise did not correlate with any subsets of QoL, mobility and self-care were significantly associated with walking exercise (OR = 0.635, 95% CI = 0.439-0.919 and OR = 0.577, 95% CI = 0.348-0.958, respectively). CONCLUSIONS: All exercisers showed higher QoL scores than non-exercisers. Among QoL subsets, mobility and self-care were independently associated with walking exercise in the MetS population. Regular walking exercise was important to higher QoL in those with MetS. This is the first clinical report to indicate that QoL could be independently influenced by walking exercise.

Oh et al. (2017) conducted a cross-sectional in Metabolic syndrome (n=7,550). Walking exercise vs. Non-exercisers was evaluated on Mobility (subset of EuroQoL) (OR 0.635, 95% CI 0.439-0.919). In a Korean population with metabolic syndrome, walking exercise was independently associated with better mobility (OR 0.635; 95% CI 0.439-0.919) and self-care compared to non-exercisers.
