NTM-1634

This study investigated the nutritional knowledge and prevalence of dietary supplements (DSs) among Iranian bodybuilders.

This cross-sectional research study involved sampling 648 bodybuilding clubs in Iran. A researcher distributed questionnaires among clubs in various regions and analyzed categorical variables, DS, nutritional knowledge, and sports nutrition data from 160 bodybuilders aged 18 and above in Iran. The analysis was conducted using the results obtained from a quantitative questionnaire.

There was a significant relationship between DS use and gender (P = 0.001, r = 0.330, males > females), bodybuilding history (P = 0.045; r = 0.158), and exercise sessions/wk (P = 0.050, r = 0.156). Whey protein (45.6%) and branched-chain amino acid (33.7%), vitamin D (50%), caffeine (34.3%), and generally vitamin C (56.2%) were the most common DS used. The most information sources for bodybuilders regarding DS were fitness coaches (35.6%) and registered dietitians/nutritionists (34.3%). Drug stores (36.7%) and fitness coaches (19.3%) were the most prominent sources for purchasing DS. Increasing performance (54.3%), increasing the need for DS through exercise (53.6%), preventing injury, and improving recovery (36.2%) were the most important reasons to consume DS. Skin problems (21.0%), increased liver enzymes (10.8%), and hair loss (9.4%) were the most common side effects of DS use. Total nutritional knowledge (macronutrients, micronutrients, and sports nutrition) was 58.6%.

This study concluded that fitness coaches and registered dietitians/nutritionists were the most common information sources for bodybuilders. It also revealed a moderate level of nutrition knowledge among bodybuilders. The most commonly used DS were vitamins C, D, and whey protein. Also, gender, bodybuilding history, and exercise sessions had a significant relationship with the prevalence of DS. However, the study also revealed some concerning findings; bodybuilders commonly experienced adverse side effects such as skin rashes, increased liver enzymes, and hair loss.

Several treatments and preventive measures for SARS-CoV-2 were studied during the pandemic, but few focused on the neonatal gut microbiome and its role in the setting of COVID-19. This case report is unique because it describes the gut microbiomes of a mother and her newborn, who both contracted COVID-19 shortly after the baby's birth. In this prospective study, on day 11 postpartum, both the newborn and mother (38 years old), of white race/ethnicity, were exposed to a COVID-19-positive person. After exposure, the mother received a 40,000 IU bolus of vitamin D orally and started a five-day course of high-dose vitamin C (10,000 mg daily), after which she continued her daily combination of vitamins C, D, and zinc pill with probiotic skyr yogurt and manuka honey. Stool specimens and DNA were extracted, quantitated, and normalized from the mother and the newborn for downstream library fabrication utilizing shotgun methodology. Baseline Bifidobacteria level for the mother was 1.5% which increased to 19% on day 15 postpartum after testing positive for COVID-19 and taking vitamin C. Neonatal Bifidobacteriasteadily increased regardless of COVID-19 infection. We propose that the disease course was altered by maternal supplementation of vitamins C and D and zinc, which may have increased Bifidobacterium levels and led to improved outcomes for both patients.
