  3. 13. Assessment of physical activity and energy expenditure in adolescents

    Författare :Ulf Ekelund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Accelerometry; Activity diary; Doubly labelled water; Heart rate monitoring; FLEX HR; Oxygen uptake; Physical activity level; Total energy expenditure; ;

    Sammanfattning : Physical activity (PA) is a complex, multidimensional human behaviour that includes all bodily movement from fidgeting to participation in marathon running. The detailed relationship (i.e. dose - response) between the type and degree of PA and its effects on various aspects of health remains to be elucidated, not least in young people. LÄS MER

  4. 14. Dietary intakes of Swedish children and adolescents

    Författare :Emma Patterson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 24-hr recall; nutritional epidemiology; dietary patterns; cardiovascular disease; food-based dietary guidelines; risk factor clustering; tracking;

    Sammanfattning : Background Knowing what children and adolescents eat, how stable their diets are, and how diet relates to other chronic disease risk factors are important issues for public health nutrition. Setting and design In 1998-9, 1120 children (grade 3) and adolescents (grade 9) took part in the European Youth Heart Study in Sweden. LÄS MER

  5. 15. Apnea, small for date and autonomic imbalance : Risk factors in relation to SIDS

    Författare :Ann Edner; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Sudden Infant Death Syndrome SIDS ; Apparent Life Threatening Event ALTE ; Small for Gestational Age SGA ; Tilt test; Heart Rate Variability HR V ;

    Sammanfattning : SIDS (Sudden Infant Death Syndrome) is defined as an infant who has died suddenly and its cause "remains unexplained after a thorough case investigation, including performance of a complete autopsy, examination of the death scene, and review of the clinical history". An infant who during sleep has been found apneic, pale or cyanotic and limp, and has required either vigorous stimulation or cardiopulmonary resuscitation is defined to have been affected of an Apparent Life Threatening Event (ALTE).
