Abstract Background: The use of dietary supplements without adequate knowledge regarding their constituents places professional athletes at great risk due to possibility of being positive in dope testing. The aim of this study was to identify the dietary supplements usage patterns among elite athletes in various sport types and investigate their knowledge and attitudes regarding that.Methods: A cross-sectional study was conducted in which a self -administered anonymous questionnaire was used to collect data from 387 elite athletes participating in individual (athletics, karate, weightlifting, wrestling and shooting), team (cricket, volleyball, netball, rugby, football, kabaddi and hockey) and both (wushu and badminton) sports. The data were analysed using nonparametric tests; Pearson’s chi square test with the level of significant of p < 0.05.Results: Out of 387 athletes, 354 (91.5%) used dietary supplements, multivitamin (57%), electrolyte (49.7%), protein (43.5%), calcium (19.7%) and creatine (17.4%) as the most prevalent types. Gender, social status, educational level, and professionalism had no impact with the supplement use whereas the type of sport played showed a significant impact on supplement intake (p < 0.05), with athletes in netball, rugby, wrestling, badminton and shooting showed 100% usage. Vitamin, protein and creatine usage were high among rugby, netball and weightlifting players (p < 0.05). The majority of athletes consume supplements to improve their performance (41.8%) and energy (54. 5%). Further,60.5% of the athletes claimed on self-prescription without medical advice. Two perceptions of, supplements are essential for maintain fitness and win awards were significantly high in males (p <0.05). Athletes having participated in educational workshops and competed internationally showed significant concern about the contamination risk associated with supplements (p < 0.05). Rugby, weightlifting and netball players showed significant multiple supplement usage among others (p <0.05).Conclusion: This study confirms that dietary supplements are readily used by Sri Lankan elite athletes, while multivitamins, protein and energy drink products are preferred. Additionally, the majority of athletes engaged in supplement use with the aim of performance enhancement and increase energy. Nature of sport played was a determinant factor of net supplement usage while higher multiple supplement usage appeared among intensive sports.

Purpose: This work evaluated the use and type of dietary supplements and home monitoring for nonneovascular age-related macular degeneration (AMD), as well as the prevalence of genetic testing among patients with AMD. Methods: A cross-sectional study was conducted of 129 participants older than 50 years who completed self-administered questionnaires regarding usage and type of dietary supplements and home monitoring, as well as the participants’ use of genetic testing for AMD. Results: Of 91 participants with AMD, 83 (91.2%) took vitamins, including 55 (60.4%) who used an Age-Related Eye Disease Study (AREDS) or AREDS2 formulation. Of 38 without AMD, 31 (81.6%) took vitamins (difference from participants with AMD = 9.6% [95% CI, 0%-23.2%]), including 2 on an AREDS formulation. Among 82 participants with AMD who were AREDS candidates (intermediate or advanced AMD in 1 or both eyes), 51 (62.2%; 95% CI, 51.7%-72.7%) took an AREDS or AREDS2 formulation, and 31 (37.8%) did not (5 were unsure). Additionally, 50 (61.0%; 95% CI, 50.4%-71.6%) AREDS candidates did some type of home monitoring. Only 1 (1.2%; 95% CI, 0%-3.6%) underwent genetic testing for AMD. Among 9 with AMD who were not AREDS candidates, 4 (44.4%) used an AREDS formulation, 4 (44.4%) did not, and 1 (11.1%) was unsure; only 1 (11.1%) of these 9 performed home monitoring. Conclusions: Despite similar results from past surveys and AREDS2 data supporting supplement use in 2013 and home monitoring in 2014, these findings suggest about one-third of AREDS candidates do not do so, providing further support for improving education regarding appropriate supplement and home monitoring usage. Genetic testing for AMD also appears infrequent.

Oral dietary supplements (DSs) include vitamins, minerals, amino acids, energy drinks, and herbal products. The use of DSs is increasing and their manufacturers promote their benefits. Studies have validated some of these benefits, but have also indicated that some DSs can have adverse effects, especially if used without the appropriate supervision. Little information on DS use among Saudis is available. This study assessed the use of dietary supplements among male and female university students with the goal of educating the community about DSs and the dangers associated with their misuse. Online and paper validated questionnaires were administered to King Abdulaziz University (KAU) students between September 2019 and January 2020. The responses were collected and analyzed statistically. Of the 954 KAU students who completed the survey, one-third used DSs (42.9% women vs 25.7% men). Of these, 51.7% believed that DSs are essential for health, 41.7% classified them as both food and drugs, 67.2% were aware that DSs could not replace a healthy diet, and 25.8% were aware of their potentially harmful effects. Multivitamins and minerals were the most used DSs. DS awareness among KAU students is limited. Additional health education is necessary to assist students in their selection of the most suitable DSs.

Backrogund/Aim. Since the beginning of competitive sports, athletes have been trying to improve their abilities by taking various substances. The problem of using prohibited substances is not strictly tied to elite athletes; it is also present in the general population. The aim of this study was to test the knowledge and attitudes of the students regarding the use of stimulative substances and dietary supplements in sports. Methods. A cross-sectional study was performed among students at the College of Health and Professional Studies in Belgrade, Serbia. The data was collected by filling in an especially designed questionnaire. Results. Knowledge of prohibited substances and methods was characterized as ?good? with 24.2% of respondents, namely 8.09% of males and 16.1% of females; knowledge of the adverse effects of prohibited substances and methods on health was demonstrated by 17.7% (9.03% of male respondents and 8.72% of female respondents). Conclusion. Student population is not knowledgeable enough about the problems of prohibited substances use and their negative effects on one?s health. The comparative analysis of our and European researches on knowledge, attitudes and uses of prohibited substances show a rather uniform prevalence rate. Not being aware of the adverse effects shows the need to further educate students.

Dietary Supplement Use

Dietary supplement use is increasing globally, especially among children. However, few studies have been conducted to examine dietary supplement use among Chinese children. The aim of this study was to examine the prevalence of dietary supplement use and the associated factors in primary school students. A cross-sectional study was conducted in four primary schools in Hunan province, China. A total of 706 Chinese parents/caregivers of school children aged 6–12 years old were enrolled. Self-administrated questionnaires were used to collect information about the children’s dietary supplement use, and their socio-demographic characteristics. The prevalence of dietary supplement use in primary school students was 20.4%. Calcium (16.7%), vitamin C (9.2%), and vitamin D (8.5%) were the most commonly used types of dietary supplement. The main reasons for parents/caregivers to purchase dietary supplements for their children were immunity improvement (43.6%), and for growth promotion (36.5%). Some caregivers (26.4%) purchased dietary supplements online, including from dubious or unknown sellers. However, 37.5% of caregivers did not receive formal guidance on supplementation even if they purchased their supplements through formal channels. Parents/caregivers were unclear about the appropriate choices for children’s dietary supplement use. Guidelines and counseling regarding dietary supplements for children may be helpful in public health work.

Purpose: This study aimed to identify dietary supplement prevalence, reasons to use, supplement types, personal beliefs, knowledge and practices of athletes related to supplement use and doping in sports. Methods: Data was collected from 386 athletes (Male; 66.8%, Female; 33.2%, Mean age ±SD; 26.22±4.9), represented national pools of 12 sport types. Results: 354 (91.5%) of athletes used supplements including multivitamin (57%), electrolyte (49.7%), protein (43.5%), calcium (19.7%) and creatine (17.4%). Gender, social status, education and profession were not found to be determinants of supplement use, but sport type did (p < 0.05). Rugby and weightlifting players showed significant protein, multivitamin and creatine use per day (p < 0.05). Many athletes consumed supplements to boost their performance (41.8%) and strength (54. 5%). The majority (60.5%) claimed about self-decided supplementation plan. Male athletes had more dope-positive attitudes than females (P<0.05). Athletes who attended anti-doping educational workshops/were exposed to international competitions were more concerned about supplement content (p <0.05). A considerable number of multivitamin (51.8%), creatine (37.3%) and protein (14.8%) users consumed them without any scientific basis. Conclusions: Dietary supplements appear to be widely consumed by Sri Lankan national-level athletes, whereas a considerable proportion does not follow proper nutritional assessment before use.

Abstract Dietary supplements have been increasingly used by gym users and are often consumed without the guidance of a health professional. Moreover, the indiscriminate supplements use can have adverse health effects, such as changes in liver and kidney function. The aim of this study was to verify the association between dietary supplements intake with alterations in the liver and kidney function among gym users. A cross-sectional study with 594 gym users (mean age 37±14 years, 55.2% women) from a city in southern Brazil. A questionnaire was used to evaluate the use of dietary supplements. The markers of the liver (alanine aminotransferase; ALT, aspartate aminotransferase; AST, alkaline phosphatase; AKP, gamma-glutamyltransferase; Gama-GT) and renal (creatinine and urea) function were also evaluated on a subsample of the study population. Data were analyzed by Binary Logistic Regression, adjusted for sex, age and education. The prevalence of dietary supplement intake was 36.0%. Individuals who intake dietary supplements showed a higher prevalence to present slight alterations in the AST enzyme and in the urea after adjustments for potential confounders. In conclusion, the use of dietary supplement was associated with slight alterations in AST enzyme and in the urea among gym users. These findings show the importance of using supplements correctly, especially with guidance from professionals trained to avoid possible risks to health.

Introduction Poor nutrition causes many chronic diseases in developed and developing countries. Dietary diversity is one indicator that reflects the state of the whole diet. Aim The study aimed to determine the diet diversity and supplement usage of nursing students of Guilan University of Medical Sciences, Iran. Material and methods In this cross-sectional study, 185 nursing students of Guilan University of Medical Sciences, Iran, participated, and the classification (relative) method was used. Information was collected through questionnaires completed in interviews. The questionnaires had three parts: demographic data, dietary diversity score (DDS; food frequency questionnaire), and supplement usage. Data was analyzed using descriptive statistics and inferential statistics. Results and discussion The results indicated that the average consump­tion rates of items from the five main food groups were 0.91 ± 0.24 scores (bread and cereals), 1.3 ± 0.49 (meat), 0.84 ± 0.59 (dairy), 0.53 ± 0.35 (cereals and vegetables), and 1.01 ± 0.58 (fruits). The findings showed that the average consumption rates of the different food categories were not similar. According to an evaluation by Kant (maximum score of 10), the average overall DDS of students was 4.60 ± 1.37 scores, which is undesirable. The highest percentage of deficiency was related to vegetables (73.67), while the lowest percentage of deficiency was related to meats (34.73). Conclusions Using DDSs is a good way to determine the diet of various communities in terms of nutritional value, and it can help predict diet adequacy. In cases of insufficient dietary diversity and supplement usage, educating people on how to follow a healthy diet is critically important for disease prevention

Dietary Supplement Use

Healthcare workers (HCWs) must be aware of the latest data supporting or refuting the use of oral dietary supplements (ODS) in order to disseminate evidence-based health information and help patients make informed decisions. Nevertheless, there is relatively scant data on the prevalence of dietary supplement use among HCWs, the types of dietary supplements recommended to patients by HCWs, and their reasons for recommending these products, particularly during the COVID-19 outbreak. This study examined the prevalence of ODS use among surveyed HCWs, considered the types of ODS used and recommended by those HCWs, identified the reasons given by those HCWs for using or not using ODS, and determined whether those HCWs were recommending or not recommending ODS to their patients during the COVID-19 pandemic. This cross-sectional study targeted all HCWs working at a district hospital in Malaysia and was conducted via a self-administered online survey. The survey revealed that 67.3% of HCWs did not recommend ODS for patient use during the pandemic, despite 55.3% of HCWs reported personal use of ODS during the pandemic. Type of HCWs (P=0.001), monthly household income (P=0.019), prior ODS use (P<0.001) and recommendation of ODS to patients (P<0.001) were significantly associated with personal ODS use during the pandemic. Vitamin C was the most commonly used (81.3%) and recommended (95.0%) ODS. “To maintain overall health and wellness” was the most common reason for personal ODS use and recommendation to patients (83.3% & 79.2%). Given the increasing rate of ODS use during the pandemic, further research should be done so that evidence-based recommendations can be formulated to ensure patient safety.
