| Objective:（1）To analyze the relationship between dietary inflammation index and obesity in female college students.（2）To explore the relationship between dietary inflammation index and obesity in female college students after adjusting the influence of physical activity,in order to reduce the incidence of obesity/overweight and maintain normal body fat level by guiding diet.Methods:A total of 178 female college students aged 18 and over,with an average age（19.84±1.56）,who met the inclusion and exclusion criteria were recruited to collect the basic information,dietary inflammation index（DII）,physical activity（PA）and obesity degree.Dietary inflammatory index was calculated by semi-quantitative Chinese food frequency questionnaire and Chinese food composition table（2009）,metabolic equivalent of total physical activity was calculated by international physical activity questionnaire（IPAQ）,and body mass index（BMI）was calculated by anthropometric measurement.The pro-inflammatory diet and anti-inflammatory diet were divided by dietary inflammation index（pro-inflammatory diet group DII>0,anti-inflammatory diet group DII<0）,DII tri-sectional quantiles grouping criteria（T1≤-1.167,-1.1670.05）.（4）DII was positively correlated with BMI（r=0.20,P<0.05）,result of partial correlation analysis shows that DII was positively correlated with BMI in female college students after controlling physical activity（r=0.21,P<0.05）.Conclusions:（1）Dietary inflammation index in female college students is positively correlated with obesity.（2）After excluding the influence of physical activity,dietary inflammation index was positively correlated with obesity in female college students.The higher the dietary inflammation index was,the stronger the dietary pro-inflammatory ability was,and the greater the risk of obesity was.The lower the dietary inflammatory index was,the stronger the dietary anti-inflammatory ability was,the lower the risk of obesity was. |
