- OBJECTIVE We investigated whether television (TV) viewing and low leisure-time physical activity in adolescence predict the metabolic syndrome in mid-adulthood.RESEARCH DESIGN AND METHODS TV viewing habits and participation in leisure-time physical activity at age 16 years were assessed by self-administered questionnaires in a population-based cohort in Northern Sweden. The presence of the metabolic syndrome at age 43 years was ascertained in 888 participants (82% of the baseline sample) using the International Diabetes Federation criteria. Odds ratios (ORs) and CIs were calculated using logistic regression.RESULTS The overall prevalence of the metabolic syndrome at age 43 years was 26.9%. Adjusted OR for the metabolic syndrome at age 43 years was 2.14 (95% CI 1.24-3.71) for those who reported "watching several shows a day" versus "one show/week" or less and 2.31 (1.13-4.69) for leisure-time physical activity "several times/month" or less compared with "daily" leisure-time physical activity at age 16 years. TV viewing at age 16 years was associated with central obesity, low HDL cholesterol, and hypertension at age 43 years, whereas low leisure-time physical activity at age 16 years was associated with central obesity and triglycerides at age 43 years.CONCLUSIONS Both TV viewing and low leisure-time physical activity in adolescence independently predicted the metabolic syndrome and several of the metabolic syndrome components in mid-adulthood. These findings suggest that reduced TV viewing in adolescence, in addition to regular physical activity, may contribute to cardiometabolic health later in life.

Leptin predicts independently a first-ever STEMI in men, data from a large prospective nested case-referent study

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Purpose: The adipocyte derived hormone leptin could be a mediator between obesity and increased risk for cardiovascular disease (CVD), asleptin has been linked to the atherosclerotic process. We hypothesised that leptin predicted independently a myocardial infarction (MI).Methods: A prospective nested case-referent study was set up within the framework of the Northern Sweden MONitoring of Trends and Determinants in CArdiovascular Diseases (MONICA) project, the Västerbotten Intervention Program (VIP), and the Mammary Screening Program (MSP). Subjects (n=564, 40% women) with a first-ever acute MI that had participated in one of these surveys prior to the MI were selected. Age, sex, survey and location matched referents (n=1082, 40% women) were selected within the surveys. Leptin was measured instored plasma. Conditional logistic regression was used to determine the risk for MI. Type of MI (STEMI and NSTEMI) was classified according to Minnesota codes.Results: The time period between survey and event was 3.9 years (interquartile range 3.6), and 51% of the cases had STEMI, 29% had NSTEMI, and 21% were unclassified. Male and female cases had higher levels of leptin (5.0 vs. 4.1 ng/mL, p<0.001 and 15.4 vs. 14.0 ng/mL, p=0.03), compared to referents. High leptin levels predicted MIindependently in men (OR 2.17 [1.32-3.54], ptrend<0.001), but not inwomen (OR 1.10 [0.55-2.18], ptrend=0.05). The risk related to leptin inmen was seen for STEMI in particular.Conclusions: High leptin predicts first–ever fatal and non–fatal MI, notably with a gender and MI-type difference. Leptin may affect theatherosclerotic process differentially in men and women and may promote plaque rupture and thrombus formation in larger coronary vessels.

- Objectives:To investigate the association between self-rated health and risk of type 2 diabetes and whether the strength of this association is consistent across five European centres.Design: Population-based prospective case-cohort study.Setting: Enrolment took place between 1992 and 2000 in five European centres (Bilthoven, Cambridge, Heidelberg, Potsdam and Umea).Participants: Self-rated health was assessed by a baseline questionnaire in 3399 incident type 2 diabetic case participants and a centre-stratified subcohort of 4619 individuals from the European Prospective Investigation into Cancer and Nutrition (EPIC)-InterAct study which was drawn from a total cohort of 340 234 participants in the EPIC.Primary outcome measure: Prentice-weighted Cox regression was used to estimate centre-specific HRs and 95% CIs for incident type 2 diabetes controlling for age, sex, centre, education, body mass index (BMI), smoking, alcohol consumption, energy intake, physical activity and hypertension. The centre-specific HRs were pooled across centres by random effects meta-analysis.Results: Low self-rated health was associated with a higher hazard of type 2 diabetes after adjusting for age and sex (pooled HR 1.67, 95% CI 1.48 to 1.88). After additional adjustment for health-related variables including BMI, the association was attenuated but remained statistically significant (pooled HR 1.29, 95% CI 1.09 to 1.53). I-2 index for heterogeneity across centres was 13.3% (p=0.33).Conclusions: Low self-rated health was associated with a higher risk of type 2 diabetes. The association could be only partly explained by other health-related variables, of which obesity was the strongest. We found no indication of heterogeneity in the association between self-rated health and type 2 diabetes mellitus across the European centres.
