- Objective: The objective of this study was to examine the predictive ability of perceived talent development environment (TDE) on the well-being of youth elite football players.Design: A field-based longitudinal design was employed.Method: The participants were 195 Swedish youth elite football players between 13 and 16 years of age enrolled at Swedish football academies. The players responded to questionnaires regarding their perceptions of their TDE, perceived stress, and well-being in the beginning of the competitive season 2012 (T1). On two more occasions, six and 12 months later, the players completed the stress and well-being questionnaires.Results: A latent class analysis, based on the TDEQ sub-scale scores at T1, revealed three classes of players with different perceptions of their TDE (one high quality, one moderate quality, and one poor qualityclass). A second-order multivariate latent growth curve model (factor-of-curves model) showed that the class of players perceiving the lowest TDE quality, experienced higher initial level of stress and lower initial level of well-being at T1 compared to the other two classes. Moreover, there were no significant differences in slopes for neither stress nor well-being between classes (the initial difference between the three groups, in well-being, remained stable over time).Conclusion: The results indicate that players perceiving their TDE as supporting and focusing on long term development seem to be less stressed and experience higher well-being than other players. Hence, in addition to facilitate sport-specific development and performance among youth athletes, high quality TDEs may be important for youth elite athletes' general well-being.

- Background:An increased risk of cardiovascular diseases (CVD) has been reported among patients with Ankylosing Spondylitis (AS). As of today, little is known what causes this increase.Objectives: The aim of this study was to evaluate whether traditional CVD risk factors, such as smoking, diet, physical activity and atherogenic blood lipids, differ among AS patients in comparison to the general population.Methods: Eighty-nine patients diagnosed with AS by fulfilling the modified New York criteria were identified in the databases of a community intervention programme, the Västerbotten Intervention Programme (VIP). The patients were compared with 356 controls matched for age, sex and study period. As part of the VIP, participants have completed questionnaires regarding diet, physical activity and smoking. Additionally, the VIP included measurement of blood pressure, height and weight, and blood samples analysed for cholesterol, serum triglycerides and blood glucose.Results: Levels of serum triglycerides (p<0.01) and cholesterol (p<0.01) were significantly lower in the patient group. Among the patients, the level of triglycerides was inversely correlated to the intake of total fat (rs = -0.25, p<0.05), monounsaturated fats (rs = -0.29, p<0.05) and positively correlated to the intake of carbohydrates (rs =0.26, p<0.05). These correlations were not seen among the controls. No significant differences were found between patients and controls regarding diet, physical activity, exercise frequency or smoking habits nor in measurements of body mass index (BMI), weight or blood pressure.Conclusions: The patients exhibited significantly lower levels of cholesterol and triglycerides compared with controls. There were correlations between diet and atherogenic blood lipids among the patients which were not found in the control group. The results suggest that there may be differences in fat metabolism among patients with AS in comparison with the general population.

- The aims of this study were to investigate, firstly, the relationship between diet and disease activity and, secondly, the presence of gastrointestinal symptoms and their relationship to diet among patients with ankylosing spondylitis (AS) using a cross-sectional design. One hundred sixty-five individuals diagnosed with AS were invited to complete a self-administered postal questionnaire regarding demographic data, diet, medication, and gastrointestinal symptoms in addition to two established disease assessment questionnaires, i.e., the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and Bath Ankylosing Spondylitis Functional Index (BASFI). No significant correlation between diet and disease activity was found. Overall, 27% of the patients reported aggravating gastrointestinal problems when consuming certain foodstuff(s). The 30% of patients who reported suffering from gastrointestinal pain had significantly greater disease activity and poorer functional status according to their BASDAI and BASFI scores (p < 0.01 and p = 0.01, respectively). Patients who reported gastrointestinal pain had a significantly higher consumption of vegetables (p < 0.01) and lower consumption of milk and soured milk (p = 0.04). No significant correlation was found between the use of non-steroidal anti-inflammatory drugs (NSAID) and gastrointestinal symptoms. In multiple regression models, BASDAI and the consumption of vegetables were independent and statistically significant predictors of gastrointestinal pain. To conclude, in a group of Swedish AS patients, no correlation between diet and disease activity could be detected. There were, however, correlations between diet and gastrointestinal pain. Gastrointestinal problems were also found to be prevalent in AS, independent of NSAID usage.

Modifiable cardiovascular risk factors in patients with ankylosing spondylitis

- The aim of this study was to evaluate whether modifiable cardiovascular disease (CVD) risk factors, e.g. atherogenic blood lipids, hypertension and lifestyle-related factors such as smoking, diet and physical inactivity, differ among patients with ankylosing spondylitis (AS) in comparison to the general population. Eighty-eight patients diagnosed with AS were identified by analysis of the databases of a previous community intervention programme, the Västerbotten intervention programme. The patients were compared with 351 controls matched for age, sex and study period. These databases include the results of blood samples analysed for cholesterol, triglycerides and plasma glucose, as well as data on hypertension, height, weight, smoking and dietary habits and physical activity. No significant differences were found between patients and controls regarding hypertension, body mass index, physical activity, diet or smoking. Levels of serum triglycerides (p < 0.01) and cholesterol (p < 0.01) were significantly lower in the patient group. Among the patients, the level of triglycerides correlated inversely with the intake of total fat (r s = −0.25, p < 0.05), monounsaturated fats (r s = −0.29, p < 0.05) and positively correlated to the intake of carbohydrates (r s = 0.26, p < 0.05). These associations were not apparent among the controls. In the cohort of AS patients studied, no differences were found regarding the modifiable risk factors for CVD compared with the general population. Hence, the increased presence of CVD in patients with AS may be caused by other factors such as differences in metabolism and medication such as NSAID or the chronic low-grade inflammation present in the disease.
