11. Metabolomics, body composition and fracture
Sammanfattning : In this thesis, I evaluated the impact of pre-centrifugation sample management on the plasma metabolome, providing verification for the protocol used in a study where I applied metabolomics to better understand the role of body composition in fracture occurrence using a large population-based cohort. In paper 1, I applied untargeted liquid chromatography-mass spectrometry (LC-MS) metabolomics analysis to plasma samples (n = 471) from healthy donors to predict and evaluate the effect of pre-centrifugation temperature and delay time on metabolomics data using a combination of random forest and generalized linear models.

12. Anthropometry in the elderly. Population studies on longitudinal changes, secular trends and risk for morbidity and mortality
Sammanfattning : The aims of this thesis were to a) describe longitudinal changes in height and body weight (BW) between the ages 70 and 95y; b) describe secular trends in height and BW of 70-year-olds and their relation to social and lifestyle factors; c) investigate waist circumference (WC) and body mass index (BMI) at age 70 as risk for stroke during a 15-y follow-up; and, d) examine the relationship between 1) BMI at age 70 and 15-y all- cause mortality, 2) the percentage of weight change from age 70 to 75 and subsequent 5- and 10-y mortality. The studies were performed within the framework of the gerontological and geriatric population studies in Göteborg, Sweden-the H70 studies. LÄS MER
13. Growth of schoolchildren : studies on somatic growth and deviant growth patterns such as weight loss and obesity and aspects of intake of breakfast and food items
Sammanfattning : The overall aim of this thesis is to explore somatic growth, and deviant growth patterns as episodes of weight loss and obesity development, including some aspects of meal patterns and food intake.Methods: The thesis includes four studies, two cross-sectional studies (Paper I and II), and two longitudinal studies (Paper III and IV).

14. Ultrasound based shear wave elastography of the liver : a non-invasive method for evaluation of liver disease
Sammanfattning : Background: Detecting liver disease at an early stage is important, given that early intervention decreases the risk of developing cirrhosis and subsequently hepatocellular cancer (HCC). The non-invasive ultrasound-based shear wave elastography (SWE) has been used clinically for a decade to assess liver stiffness. LÄS MER
15. Prenatal diagnosis of structural malformations and chromosome anomalies : Detection, influence of Body Mass Index and ways to improve screening
Sammanfattning : Introduction: Prenatal diagnosis of structural malformations and chromosome anomalies is possible in the presence of an effective screening with ultrasound during pregnancy. The continuous evolution of the ultrasound equipment facilitates the examination. LÄS MER
