Abstract
BACKGROUND Protein supplements (PSs) have gained widespread popularity among non-athlete gym attendees, who often perceive them as essential tools for muscle growth and recovery. However, misinformation surrounding PSs may lead to inappropriate use and negative health consequences. This study aimed to assess whether non-athlete gym attendees using PSs have greater misconceptions than non-users while also examining the prevalence of PS consumption and gender differences. METHODS A cross-sectional study of 387 participants in the Jazan region was conducted. Customers of 10 fitness centers were screened with a questionnaire comprising questions to measure PS misconceptions. Participants were divided into PS users and non-users. Data were analyzed using descriptive statistics and the Chi-square test to assess the associations between variables. An independent t-test was used to compare the PS Misconception Index Score between the two groups. RESULTS A total of 82.4% of non-athlete gym attendees consumed at least one PS. Our findings revealed a significant association between gender and PS utilization (P<0.001), with a higher proportion of females (90.8%) consuming PS than males (77.6%). PS users had a significantly lower PS Misconception Index Score than non-users (26.8 vs. 28.3; P=0.006), indicating that PS users had a higher number of misconceptions. The internet (41.37%) and coaches (gym instructors/trainers) (34.48%) were the most common sources of information about PSs, with muscle gain being the primary reason for consumption (82.75%). CONCLUSIONS PS consumption is highly prevalent among non-athlete gym attendees in the Jazan region, with many individuals having misconceptions about their benefits and potential risks. Targeted educational interventions are needed to promote evidence-based knowledge about PSs for gym attendees, as well as for coaches, given that they were among the primary sources of information on supplements.

Abstract
Objective: We aimed to investigate the association between university students' dietary patterns, their demographics and lifestyle in a cross-sectional study in Qatar. Participants: 370 students in eight universities in Qatar enrolled between February 2017 and February 2018. Methods: Based on a structured questionnaire, dietary patterns were identified using principal component analysis, and their associations with student characteristics were assessed using logistic regression. Results: Four dietary patterns were identified. The 'fast food' pattern was associated with being younger and male (p-values ≤ 0.1). The 'traditional diet' pattern was associated with not skipping meals or eating when bored (p-values = 0.1). The 'healthy diet' pattern was associated with regular exercise and having time to eat healthy foods (p-values ≤ 0.01). The 'protein shake' pattern was associated with being male and engaging in more vigorous physical activity (p-values ≤ 0.01). Conclusions: Our findings provide a roadmap for the prioritization of population-specific interventions in university students within Qatar and the region.

Cureus 2023; 15:e41031. [PMID: 37519554 PMCID: PMC10373514 DOI: 10.7759/cureus.41031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 06/27/2023] [Indexed: 08/01/2023] Open
Abstract
Background Dietary supplements are used for a variety of reasons, some of which are for medical conditions, to compensate for dietary insufficiency, to improve physical performance, and to boost immunity. Generally, individuals who visit sports facilities seek different benefits; it could be for health and well-being, to achieve the desired body shape, for enjoyment purposes, or as a way to socialize. To help achieve some of these goals, dietary supplements can be taken. Aims This study is designed to assess the prevalence and awareness of dietary supplement use among Saudi women who frequent fitness centers in Riyadh, Saudi Arabia. Methods A cross-sectional study was conducted in November 2021 among Saudi women who visited gyms in Riyadh, Saudi Arabia. The sample consisted of 355 participants, all of whom were women from Saudi Arabia. The statistical analysis was done using IBM Statistical Package for Social Sciences (SPSS), Version 21.0 (Armonk, NY: IBM Corp.). Necessary statistical tests such as the chi-square, the t-test, and other appropriate tests were used. A p-value of less than 0.05 has been adopted for statistical significance. Results The majority of the 355 female participants consumed dietary supplements (68.7%). The most commonly used supplements were vitamins (82.8%), amino acids and proteins (30.3%), minerals (22.1%), and fatty acids (3.3%). In the study group, 53.3% of those who were using or used supplements had previous knowledge; 13.1% were up-to-date; and 33.6% weren't. No relationship was found between supplement use and educational level, weight, body mass index (BMI), or marital status. Conclusion Dietary supplement use is common among women who visited gyms in Saudi Arabia. Vitamins were the most commonly used supplements, which suggests that users were more concerned about general health and diet deficiencies than anything else. The participants use dietary supplements cautiously; the majority consume dietary supplements under a doctor's prescription and after reading the leaflets.

Assessment of dietary supplement consumption among Italian university students: The multicenter DiSCo study. Nutrition 2023; 107:111902. [PMID: 36563434 DOI: 10.1016/j.nut.2022.111902] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2022] [Revised: 10/13/2022] [Accepted: 10/30/2022] [Indexed: 11/09/2022]
Abstract
OBJECTIVES The aim of this study was to analyze the consumption of dietary supplements (DSs) and related sociodemographic characteristics or behaviors in Italian undergraduates. METHODS A questionnaire-based, cross-sectional study was carried out between October 2021 and May 2022 involving undergraduates from 12 public universities. The use of DSs in the previous 6 mo, the aim and reason for use, the purchasing channel, and related adverse effects were explored and compared by sex. A logistic regression was performed to highlight possible associations between sociodemographic, anthropometric, and behavioral characteristics of participants and supplement consumption. RESULTS The use of DSs was reported by 71.5% of the 2165 respondents. Supplementation was related to sex (odds ratio [OR] 0.690; 95% confidence interval [CI], 0.516-0.924, for men), vegetarian or vegan (OR 4.814; 95% CI, 1.669-13.887) and other particular diet regimens (OR 1.819; 95% CI, 1.282-2.580), sport (OR 1.688; 95% CI, 1.116-2.553), and type of sport (OR 0.629; 95% CI, 0.423-0.936, for team sports). Women were more likely to use DSs following a doctor's prescription and to buy them in a pharmacy (P < 0.001) but reported more adverse effects (P = 0.018) than men. The main aim pursued was general health; proteins, amino acids, and non-caffeinated energy supplements were consumed to improve physical performance and caffeinated energy supplements for mental performance. CONCLUSIONS Diet supplementation was common in the sample examined, especially in women, and associated with particular dietary regimens and sports, especially individual sports. Female consumers follow specialists' indications more than males. These results highlight the need for educational interventions about diet supplementation for this category of users.

Abstract
La insatisfacción con la imagen corporal puede desencadenar preocupación excesiva por la estética conduciendo a una utilización indiscriminada de suplementos nutricionales. Por ello, el objetivo de este estudio fue investigar la relación entre percepción y conformidad de imagen corporal al uso de suplementos nutricionales en usuarios regulares de gimnasios de la región del Biobío, Chile. La investigación corresponde a un estudio analítico transversal realizado en el segundo semestre del año 2018, en el que participaron 262 personas mayores de 18 años. Se observó una asociación estadísticamente significativa entre el uso de suplementos nutricionales y la percepción de la imagen corporal (OR 0,58, IC95%0,34–0,98; p=0,045), y entre el uso de suplementos nutricionales y la conformidad con la imagen corporal (OR 0,43, IC95%0,25–0,75; p=0,003). En conclusión, a mayor disconformidad con la imagen corporal o la presencia de una percepción alterada de ésta, mayor es la probabilidad de consumir suplementos nutricionales.

Abstract
This research investigates the moderating role of dietary supplement intake in the relationship between MNi frequency and renal markers in gym members. A cross-sectional study was carried out with gym members of all sexes, between 20 and 59 years of age, with data on supplement use obtained via questionnaire. Renal markers (urea and creatinine) were assessed by blood collection. Buccal mucosa cells were collected to assess MNi frequency by buccal micronucleus cytome assay. Moderation was tested using multiple linear regression models by PROCESS macro for SPSS. Results showed significant interactions for supplement use (p = 0.001) and supplement type, ergogenic (p = 0.003) and sports food (p = 0.003), with MNi for urea. For creatinine, only supplement use showed interaction with MNi frequency (p = 0.048). In conclusion, supplement intake is a moderator in the relationship between MNi frequency and renal function markers in gym members.

Abstract
Despite the high prevalence of sports supplement (SS) use, efforts to profile users have not been conclusive. Studies report that 30–95% of recreational exercisers and elite athletes use SS. Research found has mostly focused on demographic and sports variables to profile SS users, but little research has studied the psychological factors that may influence the use of SS. The purpose of this investigation was to classify, describe, and differentiate the profile of users and non-users of SS, considering demographic, sports, and psychological variables. A total of 554 participants completed the questionnaire. Overall, 45% of recreational exercisers and elite athletes reported using supplements. There were significant differences found regarding the use of SS between men and women (51% vs. 49%, p = 0.002; OR = 1.799), and when training 4 or more days per week (p ≤ 0.001; OR = 1.526). Findings regarding the psychological variables have been found in the Adonis Complex. These results indicate that participants with greater concerns regarding physical appearance, tend to be SS users (p = 0.001; OR = 1.200). The results of this study fill a gap in previous research, and provide an approximate profile, including demographic, sports, and psychological variables of SS users.

Abstract
The relationship between intake of dietary supplements and biomarkers such as insulin and insulin-like growth factor has not been well explored. The primary aim of this cross-sectional study was to investigate the associations between supplement intake and biological and lifestyle factors. We hypothesized that dietary supplement intake was associated with healthier lifestyle behaviors. College students attending a Southeast university were recruited between January 2018 and April 2019. Blood samples were collected to measure insulin, insulin-like growth factor 1 (IGF-1) and alanine aminotransferase (ALT). Statistical tests employed were linear regression and analysis of variance. Ninety-eight participants completed the study and 91% reported taking at least one supplement, while 5.1% reported taking 9+ supplements once per week. There were no differences in levels of insulin, IGF-1 and ALT by levels of dietary supplement intake. Although there were no differences in HEI-2015 score among the groups, those who consumed five or more supplements met a higher percentage of the recommended intake for fruits, performed aerobic exercise for longer duration, and had lower body fat percentage compared to participants who consumed two or less supplements at least once per week. These findings are consistent with previous studies and suggest that dietary supplement intake is highly prevalent in college students, and it may be related to healthy lifestyle behaviors. Future studies should employ mixed methodology to examine reasons by which college students consume dietary supplements and to assess perceived and direct health benefits associated with consumption.

Abstract
The use of supplements containing herbal active ingredients in sport has increased in recent years. Their consumption is explained by the benefits they may provide and because their natural origin do not involve health complications, from the point of view of the consumers. The aim of this study is to analyze the availability of four supplements (caffeine, turmeric, ginseng, cannabidiol) on the internet and understand the nature of these websites. A descriptive, observational, and cross-sectional study design was used. A detailed search was carried out with specifically developed software. The searches and data evaluation took 10 days. The websites consulted correspond to those that sell supplements, or some sport websites in the case of the Spanish ones, whereas those in English belong to pharmacies, parapharmacies, or herbalists. It is concluded that the websites do not provide adequate information to ensure proper consumption and lack advice on the choices of supplements and their administration guidelines.

Abstract
Background:
Protein supplements have become a widespread practice amongst athletes
and gym users worldwide. However, studies on the use of protein supplements among
female gym users in Saudi Arabia are lacking.
Objective:
The aim of this study was to investigate the prevalence of protein supplement usage
among female gym users and their attitudes towards protein supplementation in Riyadh city,
Saudi Arabia.
Methods:
In this cross-sectional study, 502 female gym users aged ≥18 years completed a
structured, self-administered online questionnaire on the usage of protein supplementation. Socio-
demographic information, anthropometry, health status, exercise frequency, attitudes and
knowledge regarding protein supplements were obtained.
Results:
The overall prevalence rate of protein supplement use among the study respondents
was 36.3%. There were significant associations between the use of protein supplements and
educational level (p< 0.05), the duration of being a gym member (p< 0.05) and frequency of
gym visits per week (p< 0.05). Whey protein was the predominantly used supplement (57.8%),
and the reason attributed to the use of protein supplement was muscle building (53.9%). The
main sources of information regarding protein supplement use included the internet (30.2%)
followed by gym coaches (25.3%).
Conclusion:
Our findings demonstrated that a considerable number of females exercising in
gyms use protein supplements, and most rely on unreliable sources for decision-making of protein
supplements use. Nutritional education and consultations regarding protein supplement use
are warranted.

Abstract
Saudi Arabia has witnessed recent reforms and positive socio-political changes that have led to increased opportunities for women to participate in fitness centers. This study investigated protein supplement consumption among Saudi females compared with that among males and examined the knowledge and attitudes of the participants toward protein supplement use. A cross-sectional study was conducted in Riyadh using a previously validated, self-administered online survey. The questionnaire included items related to the prevalence, knowledge, attitudes, and practice of protein supplementation. The participants were 354 adults (58.2% were females). The results showed that over 47% of the participants attended fitness centers with more male (80.3%) than female (41%) attendees. Nearly 50% of the participants consumed protein supplements, with males (68.7%) using significantly (p < 0.001) more protein supplements than females (35.6%). The powdered form was most commonly consumed. The percentage of gym attendees (67.8%) who used protein supplements was higher than that among non-gym attendees (32.2%). Gaining muscles (56.1%) followed by compensating for protein deficiency (28.6%) were the reasons for taking protein supplements, with a significant gender difference (p < 0.001). Coaches provided the most information on protein supplements. The participants appeared to be knowledgeable about protein supplements. Although over 68% of protein supplement users suffered from various symptoms, only 20% of the participants thought that there was no risk in taking protein supplements, with significant gender differences. It was concluded that Saudi male participants are twice more likely to attend the gym and consume protein supplements compared with females. Of both genders, those attending the gym consumed more protein supplements than non-gym attendees.

BMC Sports Sci Med Rehabil 2021; 13:147. [PMID: 34819149 PMCID: PMC8613966 DOI: 10.1186/s13102-021-00378-x] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2021] [Accepted: 11/05/2021] [Indexed: 11/10/2022]
Abstract
BACKGROUND Among athletes, bodybuilders are more predisposed to the use of dietary supplements (DS) and hormones (H) to increase in adaptations to physical training and performance. The purpose of the study was to identify social, psychological, and organisational factors that are associated with the use of food supplements and hormones in young bodybuilders of the metropolitan area of Naples. METHODS 107 athletes, practicing bodybuilding, were consecutively recruited in 30 gyms, randomly selected in the metropolitan area of Naples. Athletes were administered an anonymous questionnaire. The questionnaire consists of 5 sections (socio-demographic, frequency and reasons for bodybuilding, knowledge, attitudes and behaviours). Descriptive statistics were performed using T-test and Chi-square statistics. A score was created for knowledge, attitudes, behaviours. Multivariable logistic regression models were employed to assess association between each score and the use of DS and H. Statistical analyses were carried out using STATA 15. RESULTS 81.31% of the subjects reported to use DS while 35.51% H. Females are less likely to practise bodybuilding frequently than males (OR 0.18 (95% CI 0.05-0.69), p = 0.01). Subjects who have attended high school or university have a lower probability of taking DS (OR 0.17 (95% CI 0.04-0.65), p = 0.01). H users also use supplements more frequently (OR 61.21 (95% CI 3.99-939.31), p < 0.001). Those who scored higher on knowledge scores are more likely to take DS (OR 1.53 (95% CI 1.11-2.12), p < 0.001). Attitudes are correlated with the use of DS; those who scored higher were less likely to use DS (OR 0.77 (95% CI 0.30-0.98), p = 0.03). People who use DS are 30 times more likely to use H at the same time (OR 30.25 (95% CI 2.51-365.24), p < 0.001). Subjects who have a higher score for knowledge and attitudes are less likely to use H (OR 0.68 (95% CI 0.54-0.87), p < 0.001, OR 0.75 (95% CI 0.62-0.90), p < 0.001). CONCLUSIONS Prevalence of H and DS' use, although lower than reported in the literature, is a worrying public health problem. Better knowledge can lead to an informed use. Gym instructors should be trained to provide accurate and scientifically sound information. Health professionals should combine their expertise to provide more comprehensive guidance to the exercisers.

Abstract
Nutritional supplements have always been a point of attractionfor physically active people. These have improved exercise performance,increased muscular strength, weight gain or weight loss,etc. The irrational use of supplements has led to various side effectsassociated with them. There is a shortage of evidence suggestingthe usage and knowledge regarding the consumption ofdietary supplements. A cross-sectional study was conducted witha 121 sample size randomly chosen from 5 different zones of thecity. A structured questionnaire was designed to collect informationwherein participants reported their demographics, physical activity,supplement usage patterns, source of information, and side effects.Descriptive statistics, chi-square test, was used with p<0.05 as significant.Samples used different dosages, forms, brands, and accessto supplements. The participants coming to the gym for moreextended periods were likely to consume supplements in higherdosages (p = 0.020). Protein powder was consumed by 97.5% ofthe samples. There was a significant association between differenttypes of supplements across gender, age group, and period of exercisingin the gym. Side effects such as cramps (p = 0.015) andnausea were significantly associated with high dosages of supplementconsumption. The majority of them (51.2%) took advice fromtrainers. Only 9.9% consulted dieticians. Individuals consumed supplementswithout the guidance of any health professionals, whichwas predisposing them to various side effects. This reflects a lackof knowledge and awareness of supplement usage and highlightseducating various stakeholders and gym-goers.

Abstract
BACKGROUND There is growing concern about the self-administration of supplements, which can often be indiscriminate, counterproductive to health, and serve as a gateway to more harmful drugs and substances. Research suggests that high uptake of performance- and image-enhancing drugs (PIEDs) is correlated with body image to accentuate masculinity. This study provides insights into limiting unhealthy supplement usage. This research identifies reasons for casual unhealthy supplement use among young adult Australians through the Theory of Planned Behavior (TPB) lens, providing practitioners with insights into developing interventions to deter their use. METHOD Semi-structured in-depth interviews were conducted with ten participants aged between 18 and 40, using a convenience sample. Leximancer analysis was used to assess word co-occurrence and map to TPB constructs. RESULTS Leximancer identified positive attitudes, social norms, and perceived behavioral control towards supplement usage. Key themes that influenced supplement use were weight loss, body image, nutrition, training, education, challenges, need, and time. Furthermore, using TPB constructs, affective and instrumental attitudes and prevailing norms were observed when investigating what would cause an individual to use supplements in an unhealthy manner. CONCLUSION Through understanding the motivations of indiscriminate supplement use across the Australian population, the study has uncovered several social factors that may reduce or limit the practice of unsafe supplement usage.

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 was conducted with 594 gym users (mean age 37 (sd 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, aspartate aminotransferase (AST), alkaline phosphatase, γ-glutamyltransferase) and renal (creatinine and urea) function were also evaluated on a subsample of the study population. Data were analysed 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.

Abstract
This research aims to understand fitness instructors and personal trainers' perception of their qualifications and competence to prescribe dietary supplements. To this end, a questionnaire was applied to 154 fitness instructors and personal trainers with professional functions in health clubs/gyms. The results obtained show that the sale of these products in gyms is seen as stimulating their consumption and that most fitness professionals consider professionals in this area do not have competence to prescribe this type of service. The lack of confidence about knowledge of dietary supplements; degree courses with a weak curriculum in this domain; and the shortage of curricular units related to dietary supplements are possible reasons for these professionals not feeling sure about giving advice on this matter. Regarding ways of updating knowledge, although these professionals consider academic journals, conferences, congresses and nutrition courses as the most reliable sources of information, they resort more frequently to the Internet, despite considering this source as the least reliable. These results can have direct implications for various stakeholders, particularly for consumers to be more informed about the risks involved in consuming dietary supplements without due orientation; for fitness professionals who have little knowledge about this type of substance; for gym managers who need to understand the implications of selling this type of product in their establishments; for teaching institutions, who should reflect on, and organize their academic curricula in order to provide sufficient grounding for fitness professionals to feel safe and confident about their knowledge in this area; and for the producers of these products, in order to improve information about, and the safety of the substances they put on the market.

Abstract
This study was aimed at evaluating the prevalence of use of dietary supplements (DSs) among gym users and gym instructors involved in body shaping-oriented fitness training. Furthermore, this study aimed to verify whether differences existed in the prevalence and in the types of DSs used in both gym users and gym instructors involved in body shaping-oriented fitness competitions vs. those not involved in fitness competitions. A survey was distributed to 316 participants, composed of 89 gym instructors and 227 gym users of both genders aged 27.3 ± 7.7. Among these participants, 52 were involved in competitions and 248 were not, while 16 participants did not specify either way. The results showed a high prevalence in the use of DSs in the population considered, with 85.4% of the participants declaring they used DSs, with high heterogeneity in the numbers and in the combinations used. No differences were found between gym instructors and gym users, or between participants involved and those not involved in competitions. The results indicate that DSs are widely used by persons involved in body shaping-oriented fitness training. The results also suggest that the majority of the participants decided individually which DSs to use.

Abstract
BACKGROUND Literature shows that the consumption of Dietary Supplements (DS) is more common in Iran. This study aimed to explore the experiences of a sample of Iranian women regarding the factors influencing the use of DS. METHODS This qualitative content analysis study was conducted in Qods city, Tehran province, Iran from January to March 2020. Forty-two semi-structured in-depth interviews were performed with women. The participants were asked about their experiences about the determinants of the consumption of DS. After the first round of the interviews was done, we performed content analysis of the data and continued up to data saturation. RESULTS Two main themes including personal factors (with 5 subthemes including sociodemographic characteristics, perceived benefits of DS, history of illness, physiological conditions, and lifestyle factors) and socio-economic factors (with 3 subthemes including subjective norms, the price of food and commercial considerations of the sectors involved in the production and sale of DS) emerged as the experiences of the participants as to the intake of DS. CONCLUSIONS These variables may suggest areas which need to be focused on for performing more effective interventions to affect appropriate consumption of DS in Iran.

Abstract
BACKGROUND The aim of this study was to screen the prevalence of supplement use in Swiss fitness center users and what information sources they consulted. METHODS Customers of 10 fitness centers were screened with a quantitative questionnaire. RESULTS Eighty two percent of the 417 fitness center users consumed at least one supplement per week. Supplement intake correlated with training frequency (rs = 0.253, p < 0.001). The most prevalent products were protein supplements (used by 49% of the study population), magnesium (34%), and multi-micronutrient supplements (31%). The average number of supplement servings per week among consumers was 17.1 (SD: 16.1, median: 11.0) and the average number of different products used was 6.9 (SD: 4.4, median: 6.0). The most frequently used information sources were the coach/trainer (28%), the website of the supplement seller (26%), and training peers (24%). Thirty seven percent were informed or informed themselves about potential risks associated with the supplement used. The leading reasons for selecting the information source were the desire for scientific-based information followed by the education level of the informing person. CONCLUSIONS A high prevalence of supplement intake among Swiss fitness center users was associated with a low level of information quality and a low prevalence of risk information. A discrepancy between a desire for high quality evidence-based information and a contrasting behavior was detected.

Abstract
PURPOSE OF REVIEW Dietary supplement usage by adolescents has been on the rise in the last decade and is expected to continue to grow, although the evidence of their benefits in healthy individuals remains unclear. This review aims to spread awareness about the poorly regulated supplements and their effects on the health of adolescents to minimize medical hazards. RECENT FINDINGS In this review, we have attempted to summarize some of the commonly consumed supplements, their alleged benefits, effects and side effects, along with the motivation that drives adolescents into consuming them. SUMMARY The widespread use of dietary supplements among adolescents, in the background of lack of knowledge and medical guidance, predisposes adolescents to significant health risks. Although supplements may be necessary and safely consumed in certain specific situations, most healthy adolescents do not need them. The lack of regulation of supplements encourages contamination and ensures indiscriminate, easy access.

Abstract
Current dietary supplement (DS) use among Saudi school students is not well described. In this study, we aim to investigate the prevalence and predictors of DS use among adolescents. This cross-sectional study collected data via self-administered questionnaire from 1221 students (12 to 18 years). The overall prevalence of DS use was 26.2%, significantly higher in females than males (33% vs. 17.9%, p < 0.001). High proportion of female DS users demonstrated normal BMI than males (84% vs. 56.5%, p < 0.001). High percentage of male DS users were engaged in vigorous and/or high physical activity (PA) levels than female DS users (58.2% vs. 43%, p = 0.022; and 57.1% vs. 20.7%, p < 0.001, respectively). The main reasons for DS use among females were vitamin deficiency (63.3%), hair condition (37.6%) and nail health (23.5%) while in males, the main reasons were vitamin deficiency (58.4%) and body building (34.4%). The predictors of DS use in Saudi adolescents included being female, having high family income and being physically active. In conclusion, the overall prevalence and preference of DS use, though low among Saudi adolescents, was driven mostly by gender, physical activity levels and socioeconomic factors like family income. DS use guidelines and counselling among Saudi adolescents are warranted to improve public health.

Prevalence of dietary supplement use by gym members in Portugal and associated factors. J Int Soc Sports Nutr 2020; 17:11. [PMID: 32093724 PMCID: PMC7038552 DOI: 10.1186/s12970-020-00342-z] [Citation(s) in RCA: 24] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2019] [Accepted: 02/14/2020] [Indexed: 11/15/2022] Open
Abstract
Background Although there seems to be an increasing interest in the use of dietary supplements in those who exercise recreationally and want to improve body composition, there is little published data regarding gym users and dietary supplement use. Methods This cross-sectional study describes the prevalence and type of supplements used by gyms members, the reasons for using them and the information source using a self-administered online questionnaire. Results Of the 459 participants (301 females) who answered the survey, 43.8% reported using dietary supplements. Users were more likely men (62.7% vs. 33.9%, p < 0.05), younger (32 ± 9 vs. 34 ± 11 years, p < 0.05) and trained more hours per week (6 ± 3 vs 4 ± 3 h, p < 0.05) than non-users. The most consumed supplements were proteins (80.1%), multivitamins and/or minerals (38.3%), sport bars (37.3%), branched-chain amino acids (BCAA’s) (36.8%) and n-3 fatty acids (35.5%). Men consumed more arginine, BCAA’s, creatine, glutamine, β-hydroxy-β-methylbutyrate (HMB), proteins, β-alanine, taurine, multivitamin/minerals, and carbohydrate supplements (p < 0.05). The most commonly cited reasons for the use of supplements were gaining muscle (55.7%), accelerating recovery (52.7%) and improving performance (47.3%). Men have more often referred increase strength, increase resistance, gain muscle mass, accelerate recovery and improve performance as reasons to use supplements than women (p < 0.05). Those who mentioned muscle gain as a reason were younger than those who did not (30.4 years vs. 33.7 years, p < 0.05). The sources of information most mentioned were registered dietitians (23.1%), internet (22.2%) and him/herself (16.6%). The majority (> 70%) of participants declared being well or very well informed about supplements, while only a minority (4%) felt very poorly or poorly informed. Most individuals purchased dietary supplements from the internet (56.2%) and supplement/health food stores (43.4%). Conclusion This study concluded that gyms users are large consumers of dietary supplements, and are more likely to be men, young, use protein powders, aiming to increase muscle mass, obtain information from registered dietitians, consider themselves well informed and buy supplements online.

Protein supplement consumption is linked to time spent exercising and high-protein content foods: A multicentric observational study. Heliyon 2019; 5:e01508. [PMID: 31025015 PMCID: PMC6475874 DOI: 10.1016/j.heliyon.2019.e01508] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2018] [Revised: 03/09/2019] [Accepted: 04/09/2019] [Indexed: 11/23/2022] Open
Abstract
The main aim of this study is to analyze if protein supplement consumption and food patterns vary across three geographical regions and secondly to identify possible factors that increase the likelihood of ingesting protein supplements. A total of 916 responses from gym users of 3 countries (Italy, Turkey and UK) were entered for analysis. Questions were related to supplement consumption (protein and other supplements), food intake and training habits. A descriptive analysis, analysis of variance (ANOVA), and logistic regression were performed. No differences were found across groups regarding: prevalence of protein supplement consumption, typology of other ingested supplement and food intake. No relation was found between level of education (r = .12) or geographical region (r = .16) and protein consumption. The analysis showed that the coach is the main source of suggestion for the intake of protein supplements (52.3%). The logistic regression model highlighted that gym users who exercised more (OR 1.51, p < 0.001) and consumed higher quantities of chicken (OR 1.39, p < 0.001) eggs (OR 1.18, p < 0.001) and canned tuna (OR 1.15, p < 0.05) were more likely to use protein supplements. Geographical area does not seem to influence the supplementation pattern. Time spent exercising and high protein foods are factors associated with protein supplement consumption.
