Metabolic Syndrome Is Associated with Health-Related Quality of Life in Suspected Patients with Nonalcoholic Steatohepatitis.

OBJECTIVE

This study was designed to examine the effect of metabolic syndrome (MetS) on health-related quality of life (HRQOL) in patients with suspected nonalcoholic steatohepatitis (NASH).

SUBJECTS AND METHODS

Three hundred thirty-two patients (236 males and 96 females) with suspected NASH from the Amol cohort study were included in this study. MetS was diagnosed based on Adult Treatment Panel III criteria and HRQOL was measured using the 12-Item Short-Form Health Survey (SF-12) questionnaire (with 8 subscales and 2 summary components). A multivariable linear regression model was used to assess the independent effect of MetS on HRQOL.

RESULTS

The mean age of the study population was 42 ± 13 years (range 18-82). The prevalence of MetS was 43.4% (n = 144) and the mean scores on the Physical Component Summary (PCS) and the Mental Component Summary were 72.4 ± 20.86 and 42.7 ± 12.42, respectively. The multivariable linear regression model showed that MetS was negatively associated with 4 subscales of HRQOL that included: role limitations due to physical problems (RP) (B = -14.05, p = 0.004), bodily pain (BP) (B = -7.37, p = 0.02), vitality (VT) (B = -7.72, p = 0.022), and role limitations due to emotional problems (RE) (B = -12.67, p = 0.005) after adjustment for other variables. Also, MetS had a borderline association with the general health and mental health subscales and the PCS (p < 0.1).

CONCLUSION

In this study, there was a strong association between MetS and 4 subscales (RP, BP, VT, and RE) of HRQOL in patients with suspected NASH; this could be considered as a part of health policy to improve general health.
