Rural Residency has a Protective Effect and Marriage is a Risk Factor for NAFLD

Background: non-alcoholic fatty liver disease (nafld) is considered the leading cause of liver disease worldwide. although many previous studies have evaluated the potential risk factors of nafld, few studies have determined the effect of residency or marriage status on nafld. objectives: we aim to evaluate whether residency and marriage status increased the risk factors for nafld. materials and methods: we utilized data from 5,052 participants, 18 years and older, from a cohort study conducted using 6,140 participants in northern iran. the population was divided into 16 subgroups according to sex and age; the age groups had an interval of 10 years. we randomly selected the subjects from each subgroup in proportion to the size of each subpopulation group. logistic regression analyses were conducted on nafld as an outcome of marriage status, residency (rural vs. urban), and other potential risk factors. results: we found that nafld had an inverse association with rural living in men (or = 0.513, 0.422 - 0.622, p value < 0.001) and women (or = 0.431, 0.345 - 0.539, p value < 0.001). furthermore, we determined that nafld had a direct association with marriage status for men (or = 2.770, 2.004 - 3.831, p value < 0.001) and women (or = 1.241, 1.033 - 1.490, p value = 0.0209). conclusions: while rural living has a protective effect on nafld, marriage may be a potential risk factor for this condition.
