Incidence of metabolic syndrome in young Japanese adults in a 6-year cohort study: The Uguisudani preventive health large-scale cohort study (UPHLS).
CONCLUSION: Our findings suggest that the incidences of MS in the 20s and 30s are lower, but account for about 20 to 50% for females and 50 to 70% for males in their 40s. However, the data are not negligible and early lifestyle intervention for MS is necessary in young adults. PMID: 31080190 [PubMed - as supplied by publisher] (Source: Journal of Epidemiology)
