Abstract
BACKGROUND: The investigation of dietary micronutrient intakes and risk of alcoholic liver disease (ALD) based on observational studies was limited.</p>
OBJECTIVES: Our study aimed to explore the associations of 30 dietary micronutrients intakes with risk of ALD, interactions between dietary micronutrients and genetic variation, and mediation effects of blood and urinary biomarkers on the associations between dietary micronutrients and risk of ALD.</p>
METHODS: A case-control study was conducted within the UK Biobank cohort, with 231 incident ALD cases and 1386 controls. Dietary data were collected using a dietary questionnaire that relied on a 24-h dietary recall of the previous day. Logistic regression models were employed to assess the associations of dietary micronutrient intakes with risk of ALD. We conducted stratified analyses on the associations between dietary micronutrient intakes and risk of ALD by PNPLA3 rs738409 and tested the interactions between dietary micronutrients and genetic variation. In addition, we conducted mediation analyses to investigate the mediating effects of biomarkers on the associations between dietary micronutrients and risk of ALD.</p>
RESULTS: Our findings indicated significant inverse associations of thiamin, riboflavin, niacin equivalent, pantothenic acid, vitamin B-6, folate, vitamin E, calcium, magnesium, phosphorus, potassium, copper, iodine, and manganese with risk of ALD (all false discovery rate-Ptrend < 0.050). We also found a significant interaction between PNPLA3 rs738409 and magnesium (Pinteraction = 0.028). Creatinine (enzymatic) in urine, aspartate aminotransferase, and insulin-like growth factor 1 were the top 3 biomarkers with the highest number of significant mediation effects on the associations between the dietary micronutrients and risk of ALD.</p>
CONCLUSIONS: Dietary intakes of thiamin, riboflavin, niacin equivalent, pantothenic acid, vitamin B-6, folate, vitamin E, calcium, magnesium, phosphorus, potassium, copper, iodine, and manganese were inversely associated with risk of ALD.</p>
