Study On The Relationship Between Dietary Patterns And Obesity,Hypertension In Adults In Inner Mongolia

ObjectiveHypertension,overweight and obesity are closely related to diet.At present,the prevalence of hypertension,overweight,obesity can be improved through effectivediet intervention.Therefore,to explore the relationship between diet patterns and hypertension,obesity that can provide an important theoretical basis for dietary guidelines,improving nutrition policies and propose measures to control hypertension and obesity.Methods The survey is a cross-sectional study,using multistage stratified random sampling method.Mmeasurement data use mean ± standard deviation((?)±s)or median(interquartile range),the comparison between groups using ANOVA or rank test;Enumeration datausing the ratio,and the comparison between groupsusing chi square test.Dietary assessment was conducted in using the Chinese Dietary Balance Index(DBI).Using logisitc regression analysis of dietary patterns and hypertension,overweight,and abdominal obesity was performed.The dietary patterns were extracted using principal component analysis.Partial correlation analysis was used to analyze the correlation between dietary patterns and laboratory indicators.Results(1)A total of 1924 subjects were enrolled in this study,including 915(47.56%)males and 1009 females(52.44%),mainly Han nationality(80.67%).(2)Overweight rate was 40.38%,obesity rate was 18.87%,abdominal obesity rate was 40.12% and prevalence of hypertension was 48.70%.The prevalence rates of obesity of urban residents(20.44%),eastern(54.59%),male(51.91%)and the animal husbandry and fishery(50.18%)were higher.The prevalence of blood pressure increase with age(Ptrend <0.001),but decrease with education level and physical activity(P trend <0.05).People who had quit and did not take weight control measures had a higher prevalence of overweight,obesity,abdominal obesity and hypertension(P<0.05).(3)Survey population taking salt reduction measures had higher BMI,WC,systolic blood pressure and diastolic blood pressure than those who did not take salt reduction measures.The mean of WC and diastolic blood pressure of out-dining were higher than those without out-dining people.(4)The subjects intakes of corn,vegetables,fruits,livestock meat,beans and nuts,eggs,milk and dairy products,aquatic products,oil and salt were 327g/d?215g/d?97g/d?102g/d?27g/d?31g/d?57g/d?9g/d?42g/d?9g/d.Vegetables,fruits,eggs,milk and dairy products,aquatic products intakes is lower than the recommended intake,livestock meat,oil and salt is higher than the recommended intake.Less than 5% achieved the recommended intake of fruits,vegetables,milk and beans,with only 14.71% of people approaching normal food diversity.(5)As the degree of dietary intake imbalance increased,the overweight and obesity rates showed a decreased trend(Ptrend<0.001),and the prevalence of hypertension increased(Ptrend<0.001).The central obesity rate firstly decreased and then increased(P trend=0.022).(6)There were five dietary patterns of vegetables and fruits high protein dietary pattern,seasoned alcoholic dietary pattern,Inner Mongolian dietary pattern,the northern traditional dietary pattern and snacking desserts dietary patterns in Inner Mongolian.(7)There was a high risk of obesity in vegetables and fruits high protein dietary pattern(OR=1.506,OR95%CI: 1.019~2.227),a high risk of abdominal obesity in the northern traditional dietary pattern(OR=1.298,OR 95%CI: 1.002~1.681),and a high risk of hypertension in seasoned alcoholic dietary pattern(OR=1.943,OR 95%CI: 1.503~2.511)and snacking desserts dietary patterns(OR=1.589,OR 95%CI: 1.191~2.119).Conclusion The prevalence of obesity and hypertension are serious in Inner Mongolia.The dietary intake is not ideal.The average daily intake of vegetables,fruits,eggs,milk and dairy products and aquatic products were low,but livestock meat,oil,salt were higher.Unbalanced diet has an impact on hypertension,overweigh,obesity and abdominalobesity and abdominal obesity.There were five dietary patterns in Inner Mongolia.Vegetables and fruits high protein dietary pattern was closely related to the obesity.The northern traditional dietary patterns was closely related to central obesity.The northern traditional dietary pattern and snacking desserts dietary patterns were closely related to hypertension.
