   Keywords : Medical sciences; homocysteine; methylenetetrahydrofolate reductase MTHFR ; first-ever stroke; first-ever myocardial infarction; longitudinal; prospective; risk factor; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Chemistry; klinisk kemi;

   Abstract : Abnormalities in homocysteine metabolism have been suggested as risk factors for stroke and myocardial infarction. In retrospective studies, elevated levels of total plasma homocysteine (tHcy) and/or methylenetetrahydrofolate reductase (MTHFR) 677C>T polymorphism have indicated an increase in risk. READ MORE

6. 4. Brain characteristics of memory decline and stability in aging : Contributions from longitudinal observations

7. 5. Anthropometry in the elderly. Population studies on longitudinal changes, secular trends and risk for morbidity and mortality

   Author : Debashish Kumar Dey; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anthropometry; height; body weight; body mass index; waist circumference; longitudinal changes; ageing; secular trends; stroke; morbidity; mortality; elderly;

   Abstract : 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. READ MORE
