    The effects of changes in musculoskeletal fitness on health

    No full text
    Le but de cette synthèse est d'analyser les effets de la modification des composantes d'une bonne condition musculosquelettique sur les indicateurs de l'état de santé. Les faits relatifs aux modifications de la condition musculosquelettique sur l'état de santé sont présentés sommairement avant d'être evalués. Les programmes concus pour améliorer spécifiquement la condition musculosquelettique se sont avérés efficaces sur plusieurs plans: métabolisme du glucose, obésite, santé des os, autonomie, incidence des chutes et des blessures consécutives, bien-être psychologique. Une meilleure condition musculosquelettique est associée à un meilleur état de santé

    DETERMINING CARDIOVASCULAR DISEASE RISK IN ELEMENTARY SCHOOL CHILDREN:

    At least 50% of children have one or more cardiovascular disease (CVD) risk factor. We aimed to 1) determine the prevalence of CVD risk factors in a sample of Canadian children, and 2) create a Healthy Heart Score that could be used in a school setting, to identify children with a greater number and severity of CVD risk factors. Children (n = 242, 122M, 120F, aged 9-11 years) were assessed for cardiovascular fitness, physical activity, systolic/diastolic blood pressure, and body mass index (BMI). Biological values were converted to age and sex specific percentiles and allocated a score. Healthy Heart Scores could range between 5 and 18, with lower scores suggesting a healthier cardiovascular profile. Seventy-seven children volunteered for blood samples in order to assess the relationship between the Healthy Heart Score and (total cholesterol (TC), high and low-density lipoprotein cholesterol (HDL, LDL) and triglycerides (TG). Fifty eight percent of children had elevated scores for at least 1 risk factor. The group mean Healthy Heart Score was 8 (2.2). The mean score was significantly higher in boys (9 (2.2)) compared with girls (8 (2.1), p < 0.01). A high score was significantly associated with a low serum HDL, a high TC:HDL and a high TG concentration. Our results support other studies showing a high prevalence of CVD risk factors in children. Our method of allocation of risk score, according to percentile, allows for creation of an age and sex specific CVD risk profile in children, which takes into account the severity of the elevated risk facto
