Association between ApoE status, circulating vitamin A and vitamin E levels with dyslipidemia in aging Chinese adults
2021
Background The influence of ApoE or lipid-soluble vitamins on lipid profile has been well documented. However, the association between ApoE status, vitamin A (VA) and vitamin E (VE) with dyslipidemia has been seldom reported. The aim of the present study was to investigate the impact of ApoE status on circulating VA and VE in aging adults with dyslipidemia. Methods A total of 1754 Chinese aged 55–75 was recruited from community health centers. They were interviewed to obtain demographic information. Food frequency questionnaire (FFQ) was used to investigate daily food intakes of the participants. Fasting venous blood samples were taken and used for serum lipid profile measurement and ApoE genotyping. Serum VA and VE concentrations were determined by using high-performance liquid chromatography (HPLC). Results Serum VE and VA concentrations were circulating lipids and ApoE status dependent. Dyslipidemia subjects showed higher serum TC, TG, HDL-c/LDL-c ratio, VE and lipid-adjusted VE levels than normal subjects. ApoE genotype-dependent differences in serum lipid profile, VE and VA levels were observed in both normal and dyslipidemia subjects. The relationship between circulating VA with dyslipidemia is modifiable by lipid status. Conclusion Higher serum VE and lipid adjusted VE levels associated with increased risk of dyslipidemia in aging Chinese adults, especially in ApoE4 carriers. Large scale longitudinal study is required to determine the optimal circulating VE levels in the elderly based on different lipid profiles and ApoE status.
