95901. The association of body mass index and osteoarthritis of the knee joint: an examination of genetic and environmental influences. Full Text available with Trip Pro

The association of body mass index and osteoarthritis of the knee joint: an examination of genetic and environmental influences. To examine the genetic and environmental influences on the known association between body mass index (BMI) and knee osteoarthritis (OA), using adult twin data.Bilateral knee radiographs were obtained from 785 pairs of healthy female twins (mean age 54.5 +/- 7.8 years) from the St. Thomas' Hospital Adult Twin Registry (261 monozygotic [MZ] and 524 dizygotic [DZ] twin (...) pairs). Tibiofemoral knee OA was graded according to the Kellgren and Lawrence (K/L) scoring system on an ordinal scale of 0-4. Presence of knee OA was defined as a K/L grade of > or =2 on either side of the knee joint. Body weight and height were measured and the subjects were stratified into quartiles of BMI. Cross-trait cross-twin association of BMI and knee OA was assessed by logistic regression, to assess whether genetic or environmental influences explain the BMI-knee OA link. The genetic

95903. Risk factors for noncontact ankle sprains in high school football players: the role of previous ankle sprains and body mass index. (Abstract)

Risk factors for noncontact ankle sprains in high school football players: the role of previous ankle sprains and body mass index. In a previous study, we noted a possible connection between an athlete's weight and risk of ankle sprain.A high body mass index and a history of a previous ankle sprain increase the risk of a subsequent noncontact sprain.Cohort study; Level of evidence, 2.One hundred fifty-two athletes from 4 football teams were observed (2 varsity and 2 junior varsity). Two teams (...) were observed for 3 seasons, and 2 teams were observed for 1 season. Before each season, body mass, height, history of previous ankle sprains, and ankle tape or brace use were recorded.There were 24 ankle sprains, of which 15 were noncontact inversion sprains (11 grade I, 3 grade II, 1 grade III; incidence, 1.08 per 1000 athlete-exposures). Injury incidence was higher in athletes with previous ankle injuries (2.60 vs 0.39; P < .001). Body mass index was also a risk factor (P < .05): injury

95904. Secular trends in the aerobic fitness test performance and body mass index of Korean children and adolescents (1968-2000). (Abstract)

Secular trends in the aerobic fitness test performance and body mass index of Korean children and adolescents (1968-2000). There is increasing evidence that the aerobic fitness performance of children is declining, at least in developed countries. To see if there was evidence of similar trends in a non-Western country, this study analysed data on 6-18-year-old Koreans tested between 1968 and 2000 using distance runs ranging from 600 to 1200 m. All existing data on the results of children's (...) . Changes in running performance showed a similar pattern to changes in estimated body mass index. Compared to other countries, there has been a sharp decline in Korean children's performance on tests of aerobic fitness, which has been concurrent with increases in estimated body mass index.

95906. Relation between serum creatinine and body mass index in elite athletes of different sport disciplines. Full Text available with Trip Pro

Relation between serum creatinine and body mass index in elite athletes of different sport disciplines. To document the relation between serum creatinine concentration and body mass index in elite athletes from five different sports, and to study potential differences among athletes performing different sports with different features and requirements.Before the start of the competitive season, serum creatinine was measured in 151 elite athletes from five different sports: rugby (n = 44), soccer (...) (n = 27), alpine skiing (n = 34), sailing (n = 22), cycling (n = 24). Pearson's correlation analysis was used to evaluate the relation between serum creatinine and body mass index (BMI). Analysis of variance and unpaired Student's t test were used to compare creatinine concentration and BMI in different sport disciplines.In the whole group of athletes, a positive correlation between serum creatinine and BMI was found (r = 0.48, p<0.001). Significant differences in creatinine concentration and BMI

Progression of age-related macular degeneration: association with body mass index, waist circumference, and waist-hip ratio. Individuals with early or intermediate stages of age-related macular degeneration (AMD) make up a large and growing segment of our elderly population. To advise these high-risk patients regarding preventive measures, we evaluated anthropomorphic, behavioral, and medical factors associated with progression to the advanced stages of AMD associated with visual loss.The (...) design was a prospective cohort study in a hospital-based retinal practice. The 261 participants were 60 years or older, with some sign of nonadvanced AMD and visual acuity of 20/200 or better in at least 1 eye. The average follow-up time was 4.6 years, and the total person-years of follow-up was 1198. Factors associated with rates of progression to advanced AMD were assessed by the Cox proportional hazards model.Progression to geographic atrophy and neovascular disease.Higher body mass index

Body mass index: a risk factor for unstable angina and myocardial infarction in patients with angiographically confirmed coronary artery disease. In patients with coronary artery disease (CAD), acute thrombosis frequently occurs in coronary arteries with only mild or moderate stenoses. Obesity increases the risk of atherosclerosis, but it is not known whether it also increases the risk of coronary thrombosis. We hypothesized that body mass index (BMI) might be an independent predictor

95914. Relationship between body mass index and local quality of mandibular bone structure in elderly individuals. (Abstract)

Relationship between body mass index and local quality of mandibular bone structure in elderly individuals. Human bones decrease in density and increase in porosity beginning at about the third decade of life. The objective of this study was to determine whether mandibular bone mineral density (BMD) and some linear radiomorphometric measurements on dental panoramic radiograph (DPR) are correlated with different categories of body mass index (BMI) in elderly individuals.Cortical width at gonion (...) (GI), at antegonion (AI), and below mental foramen (MI) and the appearance of the cortex of the lower border of the mandible distal to the mental foramina due to resorptive changes (mandibular cortical index [MCI]) were measured bilaterally on the mandible on 136 DPRs of elderly individuals. Using DPRs and copper stepwedge, mandibular BMD was investigated densitometrically. All BMD values were expressed in equivalents of the actual stepwedge thickness. The patients with BMIs from 20 to 25 kg/m(2

95919. Null mutation in human ciliary neurotrophic factor gene confers higher body mass index in males. Full Text available with Trip Pro

Null mutation in human ciliary neurotrophic factor gene confers higher body mass index in males. Ciliary neurotrophic factor (CNTF) administration reduces weight in leptin-resistant mice via the signalling pathway normally activated by leptin. A G>A null mutation in the CNTF gene results in complete absence of protein. We hypothesised that absence of CNTF could lead to diminished initiation of anorectic pathways, with consequent increase in body mass. In 575 Caucasian men aged 59-73 years
