1. 1. Evolving geriatric anthropometrics- an interplay with lifestyle changes, birth cohort effects, and survival implications. : Results from the general population study, “Good Aging in Skåne,” Sweden

   Författare :Nivetha Natarajan Gavriilidou; Geriatrik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anthropometrics; BMI misclassification; measurement; error correction; prediction equation; surrogate; survival; lifestyle; birth cohort; Swedish elderly; assessment;

   Sammanfattning : There is a rising proportion of aging population worldwide. The high vulnerability of older adults to morbidity and mortality introduces an enormous health and economic burden to themselves and the society. The established leading cause of death among older adults is due to chronic and vascular diseases. LÄS MER

3. 2. Environmental and genetic factors in lung cancer : epidemiologocal and biomolecular studies focusing on nonsmokers

   Författare :Fredrik Nyberg; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Lung cancer; case-control study; smoking misclassification; exposure misclassification; validation; bias; nonsmoker; smoking; environmental tobacco smoke; ETS; diet; biomarker; glutathione S transferase; GSTM1; N-acetyl transferase; NAT2; hypoxanthine-guanine phosphoribosiyl transferase; hprt; DNA; adducts;

   Sammanfattning : Tobacco smoking is the major cause of lung cancer. Other risk factors include exposure to environmental tobacco smoke (ETS), dietary habits and genetic factors. When studying such risk factors, confounding from smoking presents a pervasive methodological problem. LÄS MER

4. 3. Factors related to the occurrence of gastric adenocarcinoma subtypes

   Författare :Anna Mia Ekström; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :gastric; cancer; incidence; trend; cardia; Laurén; histologic; misclassification; antioxidant; completeness; vegetable; fruit; occupation; phenoxy; metal; forestry; Helicobacter pylori; smoking;

   Sammanfattning : Gastric cancer is the second most common cancer worldwide, but the etiology remains poorly understood. A spontaneous global decline has reduced the number of victims in most Western countries while Japan and China have screening programs in place due to the magnitude, and the serious prognosis, of this malignant disease.

5. 4. Fetal growth in India : studies on antenatal prediction of low birthweight and some factors that determine birthweight

   Författare :Matthews Mathai; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Fetal growth; birthweight; light for gestational age; Indian; fundal height; fetal biometry; ethnic; smoking; genital infection.;

   Sammanfattning : Objectives: To develop standards for assessment of fetal growth in India and to study some factors that determine birthweight. Methods: Data from 250 normal pregnancies were used to construct graphs of fundal height, abdominal girth and the ratio of fundal height to abdominal length. LÄS MER

7. 5. Socioeconomic inequalities in health : epidemiological studies of disease burden, mechanisms, and gender differences

   Författare :Rickard Ljung; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Burden of disease; disability-adjusted life years; socioeconomic factors; gender; misclassification; myocardial infarction; life course; risk accumulation; risk clustering;

   Sammanfattning : The overall aim of this thesis was to study inequalities in health, in particular, focusing on the risk of myocardial infarction and etiologic mechanisms from a life course perspective and on epidemiological measures and methodology. Paper I uses the Swedish Burden of Disease Study together with the Social Database managed by the Swedish National Board of Health and Welfare. LÄS MER
