Abstract:
Objective:To explore the relationship between the level of blood homocysteine (Hcy) and the total score of Chinese Healthy Eating Index (CHEI) and its item score.Methods:The subjects were recruited from the East China Natural Population Cohort Study, led by the School of Public Health in Fudan University, which was conducted in Zhongshan Community, Songjiang District of Shanghai from April to September 2017. By using the cluster random sampling method, 8 neighborhood committees were randomly selected from 18 neighborhood committees in Zhongshan community (Beimen, Baiyun, Dongwai, Huaqiao, Lantian village 1, Lantian village 2, Lantian village 4, and Lantian village 5). All the residents who met the standard and had lived in Shanghai for more than half a year were selected as research subjects. 4 995 subjects with complete survey information were finally included in this study. General information (age, sex, disease history, etc.), lifestyle (smoking, drinking, tea drinking, physical activity, etc.), food frequency and blood Hcy concentration were collected through questionnaire survey, physical examination and biological sample detection. The multivariate linear regression model was used to analyze the correlation between blood Hcy concentration and the total score of CHEI and its item score, and the multivariate logistics regression model was used to analyze the correlation between hyperhomocysteinemia (hHcy) and the total score of CHEI and its item score.Results:The age of the subjects was (56.72±9.72) years. The proportion of females, people with middle and high school education and high physical activity was 64.90% (3 241), 50.80% (2 539) and 63.20% (3 157), respectively. The blood Hcy concentration was (11.25±4.90) μmol/L, and the total prevalence of hHcy was 9.3% (467 cases). The results of multivariate linear regression showed that after adjusting for the relevant confounding factors, the blood Hcy concentration of subjects decreased with the increase of the total score of CHEI and the item score of fruit, milk, seafood, poultry and egg, but increased with the increase of the item score of total grain and tuber. In males, blood Hcy levels decreased with the increase of the item score of seafood and poultry [β (95% CI) values were -0.343 (-0.582, -0.102) and -0.225 (-0.402, -0.046), respectively]. In females, the blood Hcy level decreased with the increase of the total score of CHEI and its item score of milk, egg, seafood and poultry [β (95% CI) values were -0.130 (-0.207, -0.052), -0.091 (-0.148, -0.034), -0.016 (-0.026, -0.007), -0.069 (-0.122, -0.016), and -0.087 (-0.157, -0.017), respectively]. The results of multivariate logistic regression showed that the higher the total score of CHEI and its item score of milk and seafood, the lower the risk of hHcy [ OR (95% CI) value were 0.986 (0.978, 0.995), 0.915 (0.864, 0.969), and 0.862 (0.806, 0.922), respectively]. In females, the higher the total score of CHEI and its item score of milk and seafood, the lower the risk of hHcy [ OR (95% CI) values were 0.984 (0.970, 0.999), 0.877 (0.802, 0.958), and 0.845 (0.760, 0.941), respectively]. In males, the higher the total score of CHEI and its item score of seafood, the lower the risk of hHcy [ OR (95% CI) values were 0.988 (0.977, 0.998) and 0.858 (0.791, 0.930), respectively]. Conclusion:The dietary pattern of residents in Zhongshan Community, Songjiang District, Shanghai can affect their own blood Hcy concentration and the risk of hHcy. The total score of CHEI and the item score of fruit, milk, seafood, poultry and eggs play an important role in reducing the level of blood Hcy. The higher the total score of CHEI and the item score of milk and seafood, the lower the risk of hHcy.
