Association of Marital Status and Marital Transition With Metabolic Syndrome: Tehran Lipid and Glucose Study

BACKGROUND: Most existing reports indicate that body weight gradually increases following marital status and thereby enhances health status and decreases mortality; however, the association between marital status and the metabolic syndrome (MetS) has not been thoroughly investigated in a longitudinal study. OBJECTIVES: The aim of this study was to investigate the potential effects of marital status and marital transition on MetS during a 9.6-year follow-up in Tehran Lipid and Glucose Study. PATIENTS AND METHODS: For this study, 5221 participants (2060 males and 3161 females), aged 15 to 90 years at baseline, were followed for a median of 9.6 years. Marital status was categorized as consistent marital status and marital transition. We measured MetS risk z score and its components and calculated their changes. Then the effects of marital status and marital transition on MetS risk z score and its components were assessed using multivariable linear regression. RESULTS: In comparison to participants who were married, no significant changes in MetS risk z score was found in single participants. Employed females in the transition to married group had significant increase in MetS risk z score than single employed females. No significant changes in MetS risk z score were observed between widowed/divorced subjects and compared to consistently married subjects. CONCLUSIONS: Marital status may affect MetS risk z score differently in both genders.
