- In 2001, the INTERGENE research programme established a population-based cohort of 3614 adults living in south-western Sweden. The aim was to assess environmental, lifestyle and hereditary risk factors for cardio-metabolic and respiratory diseases, and to document secular changes in many of these characteristics. Because the focus is on coronary heart disease (CHD), the population cohort was complemented with 618 patients with acute or chronic CHD who were sampled during the examination period for the cohort (2001–04), following the same protocol. More than 800 variables describe lifestyle and socio-demographic characteristics from questionnaires, anthropometric characteristics from physical examinations, and biomarkers from blood sampled during the examination. Additional blood samples and extracted DNA are stored in biobanks. Data from the case-control study of CHD were used to investigate associations between common risk factors (overweight, smoking, alcohol consumption, sedentary behaviour) and different candidate genes with respect to CHD, and explore interactions. In addition, a biomarker for airway inflammation (Fraction of Exhaled Nitric Oxide, FENO) was investigated as a risk factor for respiratory disease, and collaboration was established with international consortia to identify genes related to respiratory and cardiovascular diseases. An update of registry information on cohort members from hospitals, general practitioners and pharmacies provides a wide spectrum of incident diagnoses and treatments between 2001 and 2014. A recently completed longitudinal follow-up of the baseline cohort will provide a further measurement point to describe changing cardiovascular risk factors in south-west Sweden. Participation at baseline was 42%, and 61% of these participated at the follow-up.

- OBJECTIVE: Apolipoprotein E genotype (APOE) polymorphism affects lipid levels and coronary heart disease (CHD) risk. However, these associations may be modified by lifestyle factors. Therefore, we studied whether smoking, physical inactivity or overweight interact with APOE on cholesterol levels and CHD risk. METHODS: Combining two Swedish case-control studies yielded 1735 CHD cases and 4654 population controls (3747 men, 2642 women). Self-reported questionnaire lifestyle data included smoking (ever [current or former regular] or never) and physical inactivity (mainly sitting leisure time). We obtained LDL cholesterol levels and APOE genotypes. CHD risk was modelled using logistic regression to obtain odds ratios (ORs) and 95% confidence intervals (CIs), adjusted for relevant covariates. RESULTS: Smoking interacted with APOE on CHD risk; adjusted ORs for ever versus never smoking were 1.45 (95% CI 1.00-2.10) in ɛ2 carriers, 2.25 (95% CI 1.90-2.68) in ɛ3 homozygotes and 2.37 (95% CI 1.85-3.04) in ɛ4 carriers. Female ɛ4 carriers had OR 3.62 (95% CI 2.32-5.63). The adjusted ORs for physical inactivity were 1.09 (95% CI 0.73-1.61), 1.34 (95% CI 1.12-1.61), and 1.79 (95% CI 1.38-2.30) in ɛ2, ɛ3ɛ3 and ɛ4 groups, respectively. No interaction was seen between overweight and APOE for CHD risk, or between any lifestyle factor and APOE for LDL cholesterol levels. CONCLUSION: The APOE ɛ2 allele counteracted CHD risk from smoking in both genders, while the ɛ4 allele was seen to potentiate this risk mainly in women. Similar ɛ2 protection and ɛ4 potentiation was suggested for CHD risk from physical inactivity.

- An elevated level of total plasma homocysteine (tHcy) has been associated with risk of coronary heart disease (CHD). The level of tHcy is affected by lifestyle, in addition to genetic predisposition. The methylene tetrahydrofolate reductase (MTHFR) 677C>T polymorphism (rs1801133) is among the strongest genetic predictors of tHcy. We examined whether the association between tHcy and CHD is modified by the MTHFR 677C>T polymorphism.
