Abstract
Objectives: To examine sex differences in the association between food label unawareness and loss of renal function among South Korean diabetic patients aged ≥30 year and determine whether reading food labels when choosing which food products to consume plays a potential role in slowing the progression of renal disease. Methods: Data from the 2016–2017 Korea National Health and Nutrition Examination Survey were used for the analysis. Renal function was determined by the Modification of Diet in Renal Disease estimated glomerular filtration rate, and food label unawareness was defined as being unaware of the food label when choosing a food product for consumption. Multiple regression analysis was used to investigate the association between food label unawareness and loss of renal function among South Korean diabetic patients. Results: Four hundred and eighty-seven diabetic patients (men: 274; women: 213) were enrolled. Loss of renal function was associated with food label unawareness in only male diabetic patients (men: β = –10.01, standard error (SE) = 5.08, p = 0.0506; women: β = –0.30, SE = 5.14, p = 0.9528). A strong association was found between loss of renal function and food label unawareness among socially isolated male diabetic patients who lived in a one-generational household, did not have a spouse, and ate alone. Conclusion: Cultivating habits of reading food labels and inducing social facilitation may play a potential role in managing loss of renal function among male diabetic patients.
Highlights
Renal disease is a global public health concern, and its prevalence has been gradually increasing in conjunction with an increase in the incidence of diabetes mellitus [1,2]
Both male and female diabetic patients who reported that they were unaware of food labels had mild loss of renal function compared to those who reported that they were aware of food labels
In 129 male diabetic patients who reported that they were unaware of food labels when choosing food products for consumption, the mean estimated glomerular filtration rate (eGFR) was 76.6 mL/min/1.73 m2
Summary
Renal disease is a global public health concern, and its prevalence has been gradually increasing in conjunction with an increase in the incidence of diabetes mellitus [1,2]. There has been convincing evidence that adoption of a Westernized lifestyle contributes to the increased diagnosis of diabetes mellitus in Asia [3]. 2014, and nearly one-third of people with diabetes had albuminuria or decreased renal function [4]. Untreated diabetes is the most common cause of end-stage renal disease and other organ complications, which contributes to the increasing mortality rate [5,6]. The progression of renal disease can be delayed, easing the burden of diabetic patients [8]
