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

Not Applicable

Completed

• Conditions: Upper Respiratory Infection
• Interventions: Dietary Supplement: Probiotics; Dietary Supplement: placebo

• Registration Number: NCT01657643
• Lead Sponsor: University of Medicine and Dentistry of New Jersey

Brief Summary

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.

Probiotics	Probiotics	Every day for 12 weeks, subjects are asked to eat 5 grams of a strawberry-flavored candy that contains probiotics \[daily dose minimum of 1 billion CFU of each Lactobacillus rhamnosus LGG® (LGG®), and Bifidobacterium animalis ssp lactis BB-12® (BB-12®)\]
Placebo	placebo	Every day for 12 weeks, subjects are asked to eat 5 grams of a placebo (strawberry-flavored candy powder)

Primary Outcome Measures

Name	Time	Method
Health-related quality of life	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.

Secondary Outcome Measures

Name	Time	Method
Missed work days	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.
