Att konsumera kosttillskott ökar i dagens samhälle. Exempel på kosttillskott är energigivande tillskott, prestationshöjande tillskott samt vitaminer och mineraler. En sammanställning av enkätundersökningar i Sverige visar att 61 % av männen och 41 % av kvinnorna konsumerar kosttillskott. Träningsverksamma upplever att produkterna är välgörande och ger positiva effekter på träningen, trots att riskerna med konsumtion av kosttillskott är omdebatterat och ett delvis obeforskat område. Bland träningsverksamma inom styrketräning förekommer även konsumtion av dopningspreparat. Dopning innebär att påverka eller förändra prestationer med olika substanser. Det finns olika slags dopningspreparat och anabola androgena steroider (AAS) är vanligast. Prevalensen av AAS har ökat under 2000-talet. I uppsatsen redovisas omfattningen av konsumtion av kosttillskott och dopningspreparat i Västmanlands län. Köns- och åldersskillnader samt samband mellan konsumtion och träningsform redovisas. Analyser har genomförts på enkätdata från Västmanlands Idrottsförbund, utifrån deras arbete med anti-dopning i Västmanland. Resultaten visar att det är vanligast att män i 17 – 30 års ålder konsumerar kosttillskott. Sannolikheten för att ha en hög konsumtion av kosttillskott ökar vid styrketräning. Socialkognitiv teori används föra att tolka den sociala aspekten på konsumtionen och ger en djupare förståelse för hur beteendet att konsumera kosttillskott och/eller dopningspreparat kan uppstå hos en individ. / Consuming dietary supplements is common in today's society. Examples of dietary supplements is energizing supplements, performance enhancing supplements and vitamins and minerals. A compilation of surveys in Sweden show that 61% of men and 41% of women consume dietary supplements. Athletes are experiencing that the products are beneficial and provides positive effects on the performance, even though there is a lack of knowledge about all the risks of consuming dietary supplement and a field partly un-researched. Consumption of doping substances also occur among athletes. Doping means to affect or change the performance with various substances. There are different types of doping substances, where anabolic androgenic steroids (AAS) are the most common. The prevalence of AAS has increased during the 2000s. The prevalence of the consumption of dietary supplements and doping in Västmanlands län are presented in the present study. Results revealed differences in gender and age and the relationship between consumption and exercise. Analyses have been performed on data from Västmanland Sports Federation, which through its anti-doping work conducted a survey in Västmanlands län. The results show that it is most common among men between the ages 17 – 30 to consume dietary supplements and to consume a few times a week or more often. The likelihood of consuming dietary supplements increases with strength training. Social cognitive theory is being used to interpret the social aspect of consumption and provides a deeper understanding for how a behavior can be developed in an individual.

The purpose of this study was to increase understanding of factors associated with nonmedical anabolic steroid use among males ages 18-30 who do not participate in intercollegiate athletics. The Behavioral Intentions and Ergogenic Aid/Performance Enhancer use among non-intercollegiate athlete males survey instrument was developed, reviewed for content validity by a jury of experts, and pilot tested. The pilot testing results (n=25) demonstrated acceptable reliability (Cronbach’s alpha= 0.74). The final version of the Behavioral Intentions and Ergogenic Aid/Performance Enhancer use among non-intercollegiate athlete males survey instrument was administered at two distribution sites which included Ford’s Fitness Center in Lexington, Kentucky and the Johnson Center on the University of Kentucky’s campus to non-intercollegiate athlete men between the ages of 18-30 (n=121). The final version of the survey instrument was also found to be reliable (Cronbach’s alpha= 0.86).Of the 121 respondents, 7 (5.9%) reported using nonmedical anabolic steroids at least 1-2 days a week or more. A total of 9 (7.4%) men reported intending to use nonmedical anabolic steroids within the next year. Age was found to have a statistically significant association with intention to use nonmedical anabolic steroids (p=.037).Perceived behavioral control (p=.029) was found to be the strongest predictor variable of study participants’ intention to use nonmedical anabolic steroids. Muscle mass builder use (p=.011) and muscle mass builder use in combination with multivitamin use (p=.000) were found to be significant predictors of actual nonmedical anabolic steroid use. Study participants were more likely to use nonmedical anabolic steroids if they were currently using a muscle mass builder or using a muscle mass builder in combination with a multivitamin. No decision about the effectiveness of the components of perceived behavioral control (self-efficacy and control) as a one or two part construct was possible because of the small number of study participants. Two additional demographic predictor variables were found to be statistically significant with predicting the intention to use nonmedical anabolic steroids. Being a competitive bodybuilder (p=.001) was positively correlated and being satisfied with body image (p=.025) was negatively correlated with the intention to use nonmedical anabolic steroids.
