title: Dietary supplementation habits and perceptions of supplement use among elite Finnish athletes.
abstract: The aim of this study was to evaluate the frequency of dietary supplement (DS) use among elite Finnish athletes in 2002 and 2009. In 2009, the authors also wanted to examine the reasons for athletes' DS use, whether athletes feel they have experienced benefits from their supplement use, and whether athletes had had an opportunity to consult dietary specialists. Cross-sectional studies were conducted in 2002 and 2009 among Finnish Olympic athletes. Data were collected using semistructured questionnaires, mainly in national team camps. The study population in 2002 was 446 athletes, and in 2009 it was 372. The number of DS users was high in both study years (81% in 2002 and 73% in 2009). Vitamin D consumption was low in both 2002 and 2009 (0.7% and 2.0%, respectively). An increase was found in consumption of omega-3 fatty acids between study years (11% in 2002 and 19% in 2009; p = .002), and their regular use nearly doubled (8% and 15%, p = .002). For vitamin and mineral users, the main reason for DS use was to prevent nutritional deficiencies, and for nutritional supplement users the main reason was recovery from exercise. Only 27% of all athletes and 30% of DS users had an opportunity to consult dietary specialists in 2009. This survey shows that supplementation rates among elite Finnish athletes are high and there may be over- and underuse of some micronutrient supplements. There is a need for professional nutritional counseling among national elite athletes.
