MedicalResearch.com: What is the background for this study? Which probiotic did you use and why?
Response: We recently reported the results of a randomized, double-blind placebo-controlled trial in which participants who were overweight or with obesity (aged between 30-65 years of age) were randomized to receive probiotics or placebo for six months. The primary focus was on weight loss and metabolism. The probiotic used was Lab4P, containing three different strains of Bifidobacteria and two of Lactobacilli, which have shown to be safe and efficacious for use in rodent models and earlier clinical studies.
Of note, probiotics have also been shown to have other beneficial effects upon human health. Previous studies have suggested that they may have a role in preventing upper respiratory tract infections (URTIs) in healthy people and children; however, this has not been explored in older people or overweight/ people with obesity, even though such groups have higher rates of URTIs.
We looked back at our trial, and reviewed symptom diaries completed by participants daily during the study. We were looking at recorded symptoms most consistent with upper respiratory tract symptoms (including cough, wheezing and headache), and explored if rates of these were different between those participants taking probiotics compared to placebo over the six month course of the study.
