合肥市50～59岁中年人群膳食模式与代谢综合征的相关性分析

Association between dietary patterns and netabolic syndrome of 50～59 year-old people in Hefei City

目的探讨合肥市50～59岁中年人群膳食模式与代谢综合征(MS)的关系。方法整群抽取接受健康检查的50～59岁的体检者。通过因子分析筛选膳食模式,了解不同膳食模式对MS发生风险的影响。结果因子分析结果得出水产肉禽豆模式、谷薯肉禽模式、蛋奶模式和蔬果模式4种膳食模式;χ2检验和多因素Logistic回归分析显示:在男性中,蔬果模式是MS的保护因素(T3∶T1 OR=0. 059,95%CI:0. 013～0. 265),并且MS的患病率随因子得分的升高而降低;在女性中,谷薯肉禽模式是MS的危险因素(T3∶T1OR=8. 516,95%CI:4. 403～16. 473),并且MS的患病率随因子得分的升高而升高;蔬果模式是MS的保护因素(T3∶T1 OR=0. 055,95%CI:0. 019～0. 158),并且MS的患病率随因子得分的升高而降低;此外,蛋奶模式的T3等分是MS的保护因素(T3∶T1 OR=0. 492,95%CI:0. 268～0. 904)。结论合肥市50～59岁中年人群膳食模式与MS的发生有一定关联,增加蔬菜水果摄入、减少碳水化合物及肉禽摄入对预防MS有重要意义。

Objective To explore the relationship between metabolic syndrome( MS) and dietary patterns ofmiddle-aged people aged 50 ~ 59 years in Hefei City. Methods Collected 50 to 59 years old physical examination patients who had undergone a health checkup by cluster sampling,and conducted questionnaires,physical examinations,and laboratory tests. Dietary patterns were screened by factor analysis to understand the effect of different dietary patterns on the risk of MS. Results The results of the factor analysis obtained four dietary patterns:aquatic product-meat and poultry-soy pattern,cereals-meat and poultry pattern,egg-milk pattern and vegetable-fruit pattern. Chi-square test and multivariate logistic regression analysis showed that the vegetable-fruit model was a protective factor for MS( T3 ∶ T1 OR = 0. 059,95% CI:0. 013 ~ 0. 265),and the prevalence of MS decreased as the factor score increased in men. In women,the cereals-meat and poultry pattern was a risk factor for MS( T3 ∶ T1 OR= 8. 516,95% CI:4. 403 ~ 16. 473),and the prevalence of MS increased as the factor score increased. The vegetable-fruit model was a protective factor for MS( T3 ∶ T1 OR = 0. 055,95% CI:0. 019 ~ 0. 158),and the prevalence of MS decreased as the factor score increased. In addition,the T3 aliquot of the egg-milk pattern was a protective factor for MS( T3 ∶ T1 OR = 0. 492,95% CI:0. 268 ~ 0. 904). Conclusion The dietary pattern of middleaged people aged 50 ~ 59 years in Hefei has a certain correlation with the occurrence of MS. Increasing the intake of fruits and vegetables and reducing the intake of carbohydrates and broilers is important for the prevention of MS.
