\n\nMethods. We conducted a cross-sectional analysis of radiographic hip OA using baseline data from the Johnston County Osteoarthritis Project, using Kellgren/Lawrence (K/L) grade, and the presence, location, and severity of 4 individual radiographic

features (joint space narrowing [JSN], subchondral cysts, sclerosis, and osteophytes). Sex-specific logistic regression was used to evaluate associations between race and individual radiographic features, adjusting for age, body mass index, education, and prior hip injury. Robust variance estimators via generalized estimating equations were used to account Galardin chemical structure for correlation between hips from the same individual.\n\nResults. The sample (n = 2,739) comprised 57% women and 31% African American participants. Among women, African Americans and whites had a similar prevalence of hip OA, defined as K/L grade >= 2 (23% versus 22%), but African American women were significantly more likely to have superior or medial JSN, moderate learn more or severe axial JSN, medial or lateral osteophytes,

and subchondral cysts. Among men, 21% of African Americans and 17% of whites had hip OA; African American men were more likely to have superior or medial JSN and lateral osteophytes, but were less likely to have axial JSN.\n\nConclusion. Individual radiographic features and patterns of hip OA differed by race among women and men, suggesting the possibility of anatomic and/or developmental variation in the hip joint. African Americans have an increased frequency of features that have been predictive of hip replacement SEN0014196 in other populations, a finding worthy of further study.”
“Background: The purpose of this study was to examine the relationship between organized sports participation, weight status, physical activity, screen time, and important food habits in a large nationally representative sample of Australian adolescents.\n\nMethods: Nationally representative cross-sectional study of 12,188 adolescents from 238 secondary schools aged between 12 and 17 years (14.47 +/- 1.25 y, 53% male, 23% overweight/obese). Participation in organized sports,

compliance with national physical activity, screen time, and fruit and vegetable consumption guidelines, and consumption of sugar-sweetened beverages and high-fat foods were self-reported. Weight status and adiposity (BMI, waist circumference) were measured.\n\nResults: Organized sports participation was higher among males and those residing in rural/remote areas. Underweight adolescents reported the lowest levels of participation. Higher levels of participation were associated with an increased likelihood of complying with national physical activity (OR = 2.07 [1.67-2.58]), screen time (OR = 1.48 [1.19-1.84]), and fruit and vegetable consumption guidelines (OR = 1.32 [1.05-1.67]). There was no association between organized sport participation and weight status, adiposity, consumption of sugar-sweetened beverages or high-fat foods.
