Adherence to healthy diet and risk of cardiovascular disease in adult survivors of childhood cancer in the St. Jude Lifetime Cohort: a cross-sectional study

BACKGROUND

Whether diet has beneficial effects on cardiovascular disease (CVD) in childhood cancer survivors as in the general population is unknown. Therefore, we examined associations between dietary patterns and risk of CVD in adult survivors of childhood cancer.

METHODS

Childhood cancer survivors, 18-65 years old in the St Jude Lifetime Cohort (1882 men and 1634 women) were included in the analysis. Dietary patterns were defined by the adherence to the Healthy Eating Index (HEI)-2015, Dietary Approaches to Stop Hypertension (DASH), and alternate Mediterranean diet (aMED) based on a food frequency questionnaire at study entry. CVD cases (323 in men and 213 in women) were defined as participants with at least one grade 2 or higher CVD-related diagnosis at baseline. Multivariable logistic regression adjusted for confounders was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) of CVD.

RESULTS

Greater adherence to HEI-2015 (OR=0.88, 95% CI: 0.75-1.03, per 10 score increment), DASH (OR=0.85, 95% CI: 0.71-1.01, per 10 score increment), and aMED (OR=0.92, 95% CI: 0.84-1.00, each score increment) were, albeit trending towards significance, associated with a lower risk of CVD in women. HEI-2015 was associated with a non-significantly lower risk of CVD in men (ORQ5 vs. Q1=0.80, 95% CI: 0.50-1.28). These dietary patterns were also associated with a lower risk of CVD in survivors with high underlying CVD risk.

CONCLUSIONS

As recommended to the general population, a diet rich in plant foods and moderate in animal foods needs to be a part of CVD management and prevention in childhood cancer survivors.

Association of lifestyle behaviors with non-alcoholic fatty liver disease and advanced fibrosis detected by transient elastography among Hispanic/Latinos adults in the U.S

OBJECTIVES

Non-alcoholic fatty liver disease (NAFLD) is a highly prevalent liver disease, with the highest prevalence observed in the U.S. among Hispanic/Latino adults. While physical activity and dietary behaviors have established protective associations with NAFLD and its severity, these associations have not been well-characterized in Hispanic/Latino adults. The purpose of this study was to assess the association of lifestyle behaviors with NAFLD and advanced fibrosis in US Hispanic/Latino adults.

DESIGN

We selected all Hispanic/Latino adults from the 2017-2018 National Health and Nutrition Examination Survey (NHANES). NAFLD was defined as CAP ≥285 dB/m, and advanced fibrosis as liver stiffness measurements ≥8.6 kPa. Multivariate-adjusted logistic regression models assessed associations of physical activity and sedentary behavior (Global Physical Activity Questionnaire), as well as diet quality (Healthy Eating Index [HEI]-2015) and total energy intake (24-hour recall) with NAFLD and advanced fibrosis.

RESULTS

In Hispanic/Latino adults, the overall prevalence of NAFLD was 41.5%, while the prevalence of advanced fibrosis among those with NAFLD was 17.2%. We found that higher levels of physical activity and high diet quality were associated with lower risk of NAFLD. Compared to those reporting on average 0 metabolic equivalent (MET) hours/week of physical activity, participants reporting high levels of physical activity (≥32 MET hours/week) had 40% lower risk of NAFLD (Adjusted OR = 0.60, 95%CI 0.38, 0.93). High diet quality (HEI-2015) was associated with a 30% lower risk of NAFLD (Adjusted OR = 0.70, 95% CI 0.51, 0.97) and 72% lower risk of advanced fibrosis (Adjusted OR = 0.28, 95% CI 0.12, 0.66), as compared to those with low diet quality.

CONCLUSIONS

In this population-based study, high levels of physical activity and diet quality were associated with lower risk of NAFLD in Hispanic/Latino adults. Public health and medical professionals need to concentrate efforts on lifestyle behavior change in Hispanic/Latino adults who are at high risk for serious liver disease.

Physical activity and diet quality in relation to non-alcoholic fatty liver disease: A cross-sectional study in a representative sample of U.S. adults using NHANES 2017-2018

The association of physical activity (PA) and diet quality with non-alcoholic fatty liver disease (NAFLD) and NAFLD-related fibrosis have never been examined in a representative sample of U.S. adults using a more precise form of measuring NAFLD. The purpose of this study was to assess the associations of PA and diet quality (Healthy Eating Index [HEI]-2015) with NAFLD and a subset with advanced fibrosis (F3-4) as assessed by vibration-controlled transient elastography with controlled attenuation parameter in a representative sample of U.S. adults. This cross-sectional analysis uses data from 2017-2018 National Health and Nutrition Examination Survey. NAFLD was defined as controlled attenuation parameter ≥285 dB/m, and high likelihood of advanced fibrosis as liver stiffness measurements ≥8.6 kPa. Associations of HEI-2015 from 24-h dietary recalls and self-reported PA and sedentary behavior were estimated in multivariable-adjusted logistic regression models of NAFLD and advanced fibrosis. In 2892 adults, the prevalence of NAFLD and advanced fibrosis was 35.6% and 5.6%, respectively. We found that high adherence to U.S. dietary recommendations (highest vs. lowest HEI-2015 tertile) and more PA (middle tertile vs. lowest) were associated with reduced odds of NAFLD (Adjusted OR and 95% CI; 0.60 (0.44, 0.84) and 0.65 (0.42, 0.99), respectively). More PA was inversely associated with advanced fibrosis (Adjusted OR = 0.35, 95%CI 0.16, 0.75). Diet quality and PA are associated with reduced odds of NAFLD, and PA may be critical even for those with advanced liver disease. These behaviors should be the focus of targeted public health interventions.
