RESUMEN
Sarcopenia is associated with NAFLD. It is unknown if the association is explained by shared risk factors. Our study sought to investigate the association between liver fat and sarcopenia in our cohort. Liver fat was measured on CT between 2008 and 2011. We excluded heavy alcohol use and missing covariates. Muscle mass in a subset (n = 485) was measured by 24 h urinary creatinine. Physical function was defined by h strength and walking speed. Sarcopenia was defined as low muscle mass and/or low physical function. We created multivariable-adjusted regression models to evaluate cross-sectional associations between liver fat and low muscle mass, grip strength, and walking speed. The prevalence of hepatic steatosis was 30% (n = 1073; 58.1% women; mean age 65.8 ± 8.6 years). There was a significant positive association between liver fat and muscle mass in linear regression models. The association was not significant after adjusting for BMI. The odds of sarcopenia increased by 28% for each SD in liver fat (OR 1.28; 95% CI 1.02, 1.60) and persisted after accounting for confounders in multivariable-adjusted models (OR 1.30, 95% CI 1.02, 1.67). Further studies are needed to determine if there is a causal relationship between liver fat and sarcopenia and whether treatment of sarcopenia improves liver fat.
RESUMEN
BACKGROUND AND AIMS: Patients with inflammatory bowel disease (IBD) and underrepresented minorities (URMs) historically have below average vaccination rates. URMs have increased morbidity and mortality from COVID-19. We surveyed IBD patients to assess COVID vaccination attitudes, particularly among URMs. METHODS: In May and June 2021, all 822 adult patients with IBD, medically homed at a tertiary IBD referral center and safety net hospital, and with access to the electronic patient portal, were sent an electronic survey assessing their attitudes regarding COVID-19 vaccination. An additional 115 without access to the patient portal were contacted by phone. Demographic and clinical data were recorded. The primary outcome was vaccination hesitancy, defined as: likely will become vaccinated later this year, but not immediately; unsure if they will get the vaccine; or do not want the vaccine. Multivariable logistic regression was used to calculate adjusted odds ratios (aOR) of factors associated with vaccination intent. RESULTS: The mean age was 46.6 years (SD 15.1). 210/1029 patients responded to the survey: 150/822 (18.2%) electronically and 60/115 (52.2%) by phone. Overall vaccine hesitancy rate was 11.9%, significantly higher in younger (aOR for 10-year increments, 0.64; 95% confidence interval [CI], 0.46-0.90, p = 0.011), Hispanic (aOR, 7.67; 95% CI, 2.99-21.3, p < 0.0002), and Black patients (aOR, 3.52; 95% CI 1.11-11.1, p = 0.050). Safety concerns were the most cited reasons for vaccine hesitancy. CONCLUSIONS: URM patients were more vaccine hesitant. Future studies should further explore factors leading to lower vaccination rates among these groups and strategies to improve COVID-19 vaccination rates.
