Differences in the Number of Intestinal Bacteria in the Different BMI Groups of College Students
摘要
Abstract
Objective To investigate the quantity variance of segmental intestinal bacteria in undergraduate with dif erent BMI.Methods According to the Body Mass Index (BMI) criteria,Fecal samples were col ected from 16 students as BMI≥24(overweight group),11 students with BMI≤18.5 (lean group)and 19 students with 18.5≤BMI≤24(normal group).Bacteria which cultured by TSC、PS and EMB mediums respectively under aerobic condition were counted through live bacteria counting method.The quantity variances between groups were compared.Results Bacteria's number in three kinds of medium with disparate BMI exist dif erences. Using pairwise comparison,in TSC mediums,the counts of bacteria colony in overweight and lean group were both higher than normal group,but without statistical significance ( >0.05);In PS mediums,the counts of bacteria colony in lean group contained significant increase than normal group ( <0.05);In EMB mediums,the counts of bacteria colony in lean group were significant more than both normal and overweight group,besides,with the development of BMI index,a decreased trend showed in number of bacteria.Conclusion There are quantity variances of bacterial structure in undergraduates' excrement with dif erent BMI.关键词
