    Background: Adequate nutritional intake plays a pivotal role in optimizing performance, recovery, and body composition goals. This study aimed to investigate the dietary intakes (DIs); nutritional knowledge (NK); and attitudes, perceptions, and challenges (APC) of semiprofessional rugby players in Scotland. Methods: Dietary intakes and NK of 24 male semiprofessional rugby players of a Super6 club were evaluated using validated questionnaires. Players were categorized as having good or poor NK according to NK scores. Diet-related APCs were assessed using researcher-developed questionnaires and 1-1 semi-structured interviews. Results: Mean ± SD total NK% was poor, 53.7 ± 11.9%. The ‘Good’ NK group scored significantly higher in the Weight Management (p = 0.014), Macronutrients (p < 0.001), Micronutrients (p = 0.001), and Sports Nutrition (p < 0.001) sections. Mean DIs from food sources were 26.3 ± 9.2 kcal/kg/ day energy, 1.4 ± 0.4 g/kg/day protein, and 21.7 ± 10.1 g/day fibre. Median (25th,75th) carbohydrate intake was 3.0 (2.0, 3.0) g/kg/day, and 6.3 (2.3, 10.6) units/week alcohol. Mean ± SD fat and saturated fat (SFA) % total energy intake (EI) were 36.2 ± 3.7% and 12.8 ± 1.9%, respectively, and SFA %EI exceeded recommendations (p < 0.001). The ‘Good’ NK group had significantly higher intakes of all macronutrients (p < 0.05). Total NK% positively correlated with intakes of meat (r = 0.556, p = 0.011), cereals (r = 0.458, p = 0.042), dietary fat (r = 0.477, p = 0.034), vegetables (r = 0.487, p = 0.030), and alcoholic beverages (r = 0.541, p = 0.014). Supplement use was 68%. Players felt diet affected performance (94%) but 31% of them were unaware of any specific nutritional strategies. A healthy diet was perceived to be ‘balanced’ with ‘variety from all food groups. Lack of time for preparation was described as the main barrier to healthy eating. Conclusions: Overall, players had poor NK, their fibre and carbohydrate intake was suboptimal, whereas saturated fat intake exceeded recommendations. Many lacked awareness of current sports nutrition guidelines. Further nutrition education may be needed to improve diet quality and aid performance goals.

    Knowledge, attitudes and perceptions towards Vitamin D in a UK adult population: A cross-sectional study
    (MDPI, 2018-10-27) O’Connor, Clodagh; Glatt, Dominique; White, Lois; Revuelta-Iniesta, Raquel
    The prevalence of vitamin D deficiency in the United Kingdom is high, despite updated Scientific Advisory Committee on Nutrition (SACN) guidelines. Therefore, our aims were to identify population knowledge, attitudes and perceptions of vitamin D supplementation and factors contributing to supplement use in a UK adult population. A cross-sectional study was performed between April–June 2018 using a newly designed piloted questionnaire. Scores for knowledge were calculated as a percentage (Boland et al. 2015). Logistic regression analysis was used to predict supplement use. 209 participants (82% female), mean (±SD) age 34.9 (±12.3) completed the questionnaire. The mean (±SD) vitamin D knowledge score was 56.6% (±19.9%); only 48% were concerned about their vitamin D concentration and 57% did not take vitamin D. Most participants (86%) wished to learn more about vitamin D. Knowledge score (OR 2.5; p = 0.01; 95% CI 1.2–5.3), concern (OR 2.1; p = 0.03; 95% CI 1.0–4.2) and location (OR 0.3; p = 0.006; 95% CI 0.1–0.7) predicted supplemented use. Individuals living in England had 2.9 (95% CI 1.4–6.3) lower odds of taking vitamin D than those living in Scotland. As a result of these findings, this study suggests that vitamin D supplementation and fortification, alongside education strategies, may be an effective method for improving UK vitamin D health; however, more research is warranted.
