Study On The Correlation Between Dietary Patterns And Metabolic Syndrome Among Residents In Xiamen

ObjectiveTo investigate the dietary patterns and the prevalence of the metabolic syndrome(MS)and each MS component among residents in Xiamen.To explore the associations of dietary patterns with the risk of MS and each MS component.To investigate the related risk factors of MS and provide reference for further prevention and control of MS.MethodsA multiple stage probability proportionate to size sampling was adopted to analyze the ditetary,examining the physical situations and measuring the blood pressures among 2508 residents aged 18 years old or older from 24 points of investigation from December 2015 and September 2016.The general survey was conducted using a questionnaire survey,the dietary survey was conducted using a dietary frequency method,Physical measurements included height,weight,and blood pressure,measurements biochemical tests included fasting blood glucose(FPG),high density lipoprotein cholesterol(HDL-C),serum triglyceride(TG)and so on.Using SPSS statistical software to sort out the basic situation of the investigation.The differences of systolic blood pressure(SBP),diastolic blood pressure(DBP),FPG,TG and HDL-C between men and women were compared by independent sample t test.Chi-square analysis was used to analyze the difference of MS prevalence among men and women under different age,marital status,educational level and BMI level.Factor analysis was used to identify the dietary patterns.People were sorted into 3 equal parts of each dietary pattern.Chi-square trends analysis was used to analyze the trend relevance of the prevalence of MS and each MS component and dietary patterns.Logistic regression was used to analyze the protective and harmfull effects of food patterns.Results1.Prevalence of MS and its componentsOverall,the prevalence of the MS was 6.38%,95%confidence interval(5.42%,7.26%),In male and female,the prevalence of MS was 6.80%and 6.16%.the prevalence of MS was 0.78%among 18?29 years old-group,the prevalence of MS was 2.38%among 30?39 years old-group,the prevalence of MS was 6.20%among 40?49 years old-group,the prevalence of MS was 9.38%among 50?59 years old-group,at the age of 60 and above,the prevalence of MS was 11.13%.2.Intake of different foodsThe intake amount of valley potato and vegetables in daily life met the recommendation approval of Chinese Balanced Diet Pagoda(99.33%).At the same time,the intake amount of livestock and poultry meat was beyond the Chinese Balanced Diet Pagoda recommendation level up to 241.33%.Furthermore,about the aquatic products,fruits and milk,the intake amount was under Chinese Balanced Diet Pagoda criteria which showed(42.00%),(57.00%)and(21.66%)respectively.3.The relationship between dietary patterns of male and MSAmong investigation subjects,there were four dietary patterns about male such as condiment pattern,milk and fruit pattern,Minnan characteristic pattern as well as vegetable and meat pattern.After controlling for confounding factors,the results of risk factors via multivariate logistic regression analysis showed as following:the condiment pattern(T3:T1OR=2.64,95%CI=1.10?6.36),BM>25kg/m2(T3:T1OR=1.53,95%CI=1.05?2.23),hypertension(T3:T1OR=2.95.95%CI=1.68-5.17),high serum TG level(T3:T10R=1.74,95%CI=1.13?2.68),low serum HDL-C level(T3:T1OR=1.97,95%CI=1.34?2.90).Otherwise,this study did not present any significant correlation between the other three patterns and MS.4.The relationship between dietary patterns of female and MS.Among investigation subjects,there were four dietary patterns about female such as high sugar high fat pattern.Minnan characteristic pattern,condiment pattern as well as fruit and milk pattern.After controlling for confounding factors,the results of risk factors via multivariate logistic regression analysis showed as following:High sugar and fat was the risk factor of hypertension(T3:T1OR=1.88,95%Ci=1.30?2.73);Minnan characteristics pattern was the risk factor of MS component with low serum HDL-C(T3:T 1OR= 1.29,95%CI=1.01?1.64);fruit and milk pattern was the risk factor of MS(T3:T1OR=0.53,95%CI=0.31?0.92)and the protect factor of hypertension(T3:T1OR=0.68,95%CI=0.48?0.96).Otherwise,this study did not present any significant correlation between the condiment model and MS.Conclusions1.The prevalence of MS in the survey population was low,6.38%.There was no statistically significant difference in prevalence between males and females.The prevalence of MS increased with age.2.The dietary structure of the investigated population was unreasonable,poultry meat meat,edible oil intake exceeded the recommended amount of Chinese Balanced Diet Pagoda,Aquatic products,fruits,dairy products intake was lower than the recommended amount of Chinese Balanced Diet Pagoda.3.In the male survey population,a total of 4 dietary patterns were obtained,which were condiment pattern,milk and fruit pattern,Minnan characteristic pattern,vegetable and meat pattern.High scores of condiment pattern had higher risks of MS,BMI>25kg/m2,hypertension.hypertriglyceridemia and low HDL cholesterol.4.In the female survey population,a total of 4 dietary patterns were obtained,which were high sugar and fat pattern,Minnan characteristic pattern,condiment pattern and fruit and milk pattern.High scores of high sugar and fat pattern had higher risks of hypertension;High scores of Minnan characteristic pattern had higher risks of low HDL cholesterol;High scores of fruit and milk pattern had protective effect on MS and hypertension.
