The current study was conducted at Elite, curves and fitness time centers at Holy Capital of Makkah. Sample size will be total of 190 participants. They would be 65 (34%) female volunteers and 125 (66%) male volunteers. Results: Overall, our participants who did not suffer side effects of supplements were constitutes 78.6 % the significant difference between education status and using supplements in the study while Chi-square 18.906 & p-value more than 0.05. The Sports Trainer was the most sources to obtain information in study group constitutes 24.9% then the second source to obtain information was Magazines and newspapers constitutes 23.7 % then friends constitutes 17.9%. The significant difference between food supplements used and gender in study group While Chi-square 28.349 & p-value more than 0.05. Conclusion: The prevalence of dietary supplement use was high and was significantly associated with socio demographic and lifestyle factors. A substantial proportion of populations take supplements. Further investigation into the social, psychological and economic determinants that motivate the use of supplements is required, to ensure appropriate use of supplements among adults.

1. Introduction

Definition of a product taken orally that contains one or more ingredients (such as vitamins, minerals, herbs or amino acids) that are intended to supplement one's diet. ¹ They might be sold as a dietary supplement in the United States under the Dietary Supplement Health and Education Act of 1994. ² Batches of a dietary supplement L-tryptophan that have been implicated in a mysterious disease were produced by a genetically engineered organism. ³ Saudi Arabia is a vast country with about 31.74 million populations. Nearly two-thirds of them are adults. ⁴ Sports dietary supplements are out there purchasable publicly places as well as sports clubs. members World Health Organization often sees and consumes them. ⁵ Which sees the public as an active part of the process and not a passive one. ⁶ The public’s risk perception is influenced by personal, psychological, environmental and social factors. So as to speak the danger, there's a requirement to require the danger communication approach to make an interactive method of exchanging information and opinions among people, teams. ⁷ Dietary Supplement Health and Education Act of 1994 is defined DSs as any" Product" (other than tobacco) designed to supplement the diet. ⁸ Aging is often accompanied the middle of hyperbolic nutritionary risk which will cause or exacerbate health conditions. Under nutrition in older adults may be because of reduced energy and food intake, biological changes within the systema alimentarium, medical and psychological conditions, polypharmacy, and social problems like economic condition and therefore the inability to buy and prepare meals. ⁹ It well documented that the use of some of these products may lead to critical health injury. It means that the regular users are at risk resulting from taking various categories of DSs intended for athletic improvement. ¹⁰ dietary supplement (DS) use is widespread, with over 1/2 adults’ news use, and also the highest use rumored in older adults. ¹¹

A cross-sectional study, published in Journal of Nutrition and Metabolism in April 2017 was conducted in Riyadh among regular gymnasiums. The aim of study to determine the prevalence of DSs use. A validated structured questionnaire used. The study showed that 113 (37.8%) individuals out of 299 participants were DSs user.

This consumption was less frequent in females than males (16.4% versus 44.7%) The most ordinarily used supplements were whey protein (22.1%). The causes for taking dietary supplements were to improve body shape (47.7%). nutrients provided by DSs can also potentially lead to intakes exceeding the Tolerable Upper Intake Level (UL), especially for nutrients that are fortified in the US food supply. Moreover, some botanical and herbal DSs cause adverse reactions with prescription and over-the-counter drugs. ¹²

In 2013, the Journal of Nutrition and Metabolism had published an article targeted to understand the patterns of using DSs among professional athletes in Saudi Arabia. ¹³ Although often used with an intention of improving or maintaining health, it was estimated that in 2007-2010 only 23% of all supplement products were used at the recommendation of a health care provider. ¹⁴

Journal of Family and Community Medicine have published a cross-sectional study in early 2017 about nutrition and hormones among Gyms' Attendees in Riyadh to assess the prevalence of supplements use and their types and to obtain the main reasons of that enhancement . There was an apparent association between DSs consumption and hormone use. ¹⁵ Results from observational studies have yielded mixed results regarding the health benefits of individual supplements or multivitamins/multiminerals (MVMM), and randomized clinical trials have often not supported benefits of these supplements, although the duration of many randomized clinical trials may have been insufficient to observe beneficial effects. ¹⁶

In Sharjah, the United Arab Emirates, a study of gym users with 320 participants showed a high prevalence of DSs use, 43.8%. DSs use was more common among males than females (47.7% versus 28.1%). The reasons for using DSs differed between males and females. 60.7% Approximately was also used of users were self or commercially prescribed with only 12.8% were professionally advised. ¹⁷ Their use may be motivated, in part, by evidence suggesting that increased intake of some dietary constituents may be associated with reduced risk of outcomes, including cancer and cardiovascular disease. ¹⁸

The first study investigated DSs use in Middle East was conducted in Beirut, published in Journal of Nutrition and Metabolism in 2012. It was a cross-sectional survey among 512 exercisers between 20 and 50 years old. The study showed that 36.3% of the participants were DSs users despite professional supervision. ¹⁹ The high concurrent use of prescription medications and DSs in older adults may increase the risk of drug-nutrient and other drug-supplement interactions. Thus, DSs have the potential to be both beneficial and harmful to health, and it is important to monitor usage patterns in this rapidly growing segment of the US population aged ≥60 y ²⁰. A large meta-analysis and systematic review were conducted over 159 studies in the United States of America at 2017. Athletes were using DSs much more than USA general population. The use in male and female was the same except that males were using more protein, Creatine and vitamin E than females. On another hand female were using more iron ²¹.

The researcher is a physically active person. She joined several fitness centers in Makkah in the last years. She noticed that DSs were widely used between adult gymnasiums. The researcher failed to lay a hand on previous studies conduct the same subject among athletes In Makkah Al Mukrramah city.

4. Discussion

The present study demonstrated the high prevalence of dietary supplement use and its association with socio demographic and lifestyle factors in Adults in Makkah Almukrramah at King Saudi Arabia. The association between education level and dietary supplement use has been in study. A significant direct association of level of education and dietary supplement use in the adult population. A significantly higher consumption of vitamins and/or mineral food supplements in females with educational status. Our present study supports the above findings showing a significant direct association between level of education and Food supplements used and gender in study group While Chi-square 28.349 & P 0.019 While p-value more than 0.05.

Studies across completely different populations and sex show a healthier manner related to dietary supplement (men and women) that dietary supplement use. Participants lack correct data and basic information concerning aspect effects, importance of doctor’s prescription and reliable supply. These findings can't be generalized thanks to little sample size, that isn't representative of the population in Kingdom of Saudi Arabia. Thanks to the cross-sectional style of this study, the reported associations, significantly with relevance socio demographic/lifestyle characteristic and health outcomes couldn't establish relation.

5. Conclusion

Lack of awareness of risks suggests that there's a requirement for communication on this issue. We tend to advocate that professionals (physicians and dietitians) be present in sports clubs that sell such products in an uncontrolled method. The prevalence of dietary supplement use was high and was considerably related to socio demographic and style factors. A considerable proportion of populations take supplements. Any investigation into the social, psychological and economic determinants that encourage the employment of supplements is needed, to confirm applicable use of supplements among adults.

6. Recommendations

Future studies can add perspectives of additional populations who work out. Most consumers lacked knowledge about supplement side effects, and further research should ascertain whether risk communication might affect participants’ awareness of risks. This study also indicates that the information about SDS is gleaned particularly from the internet and friends; further studies should research the distribution of information on the internet.
