Effect of Probiotics on Health-related Quality of Life in College Students With Upper Respiratory Infections

May 26, 2015 updated by: SHRP nutritional sciences, University of Medicine and Dentistry of New Jersey

Effect of Lactobacillus Rhamnosus LGG® and Bifidobacterium Animalis Ssp Lactis BB-12® on Health-related Quality of Life in College Students With Upper Respiratory Infections

The main purpose of the study is to find out if probiotics (healthy bacteria found in yogurt) can improve the health-related quality of life (HRQL) during upper respiratory infections (like the common cold) in college students living in residence hall on-campus at Framingham State University (Framingham, MA) who are randomized to receive a probiotic or placebo candy daily for 12 weeks. HRQL is a subjective measure, defined as the aspects of quality of life (i.e., one's satisfaction with their life) that related specifically to a person's health (for example, ability to carry out normal daily activities). The investigators hypothesize that HRQL during URIs will be significantly higher in the probiotic groups compared to the placebo group. The proposed study will also seek to address the following secondary objectives: missed school and work days due to a upper respiratory infection.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Health-related quality of life
Time Frame: 12 weeks
Subjects are asked to complete a questionnaire every day for 12 weeks that inquires about any common cold symptoms that they may be experiencing, severity of the symptoms, and how the symptoms interfere with their daily activities. Health-related quality of life is operationalized by total score on the questionnaire.
12 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Missed work days
Time Frame: Once per week over the course of 12 weeks
Once per week, for 12 weeks, subjects are asked to complete a questionnaire that inquires about missed work days.
Once per week over the course of 12 weeks

Other Outcome Measures
