The combined effect of physical exercise and weight change on change in blood pressure: The HUNT study, Norway

摘要: Background: Both weight change and physical activity have been shown to be individual factors that affect blood pressure, but the combined effect of is still debated. Objectives: To investigate effects on long term changes in both systolic-and diastolic pressure. Design: A population- based longitudinal study, using baseline data from 1984-1986 follow-up information 1995-1997. Setting: The Nord-Trondelag Health Study (HUNT). Subjects: We included 39 312 Norwegian subjects (18 727 men 20 585 women) who were year or older first survey, without pressure medication, diabetes, cardiovascular disease movement dysfunction, had sufficient weight, height, activity, any other variable required this analysis. Measurements: Height, measured standardized procedures at surveys. classified into following categories; ≤-5.0, -4.9 -2.1, ±2.0 (stable), 2.1-4.9, 5.0-9.9, 10.0-14.9, 15.0-19.9, ≥20.0 kg. Physical was as frequency, intensity, duration, we also constructed a summary score by combining three factors. Based score, with five categories reflects total exercise volume: No <1 per week, low medium high score. Results: An increase decrease significantly associated increased systolic- sexes. Men highest systolic 6.83 mmHg (95% CI, -8.01 -5.66) lower than reference group stable whereas gain 6.12 4.09 8.15) higher. corresponding for women 6.39 CI,-7.53 -5.26) lower, 8.34 6.79 9.90) higher group. significant association between found. In analysis most pronounced factor, little no contribution exercise. Conclusion: Our results support independent Weight strongest predictor analyses,
