Abstract MP14: Preventable Stroke and Ischaemic Heart Disease Deaths in Argentina Comparative Risk Assessment of Different Levels of Physical Activity
Introduction: In Argentina physical inactivity was the fifth leading risk factor for all-cause mortality in 2010. The aim of this project was to estimate the numbers of ischaemic heart disease (IHD) and stroke deaths in Argentina attributable to different levels of physical activity (PA).
Materials and Methods: We conducted a population-level comparative risk assessment for different levels of PA. We obtained data on prevalence of different levels of PA from the Argentinian national survey of risk factors 2013 and used relative risk for stroke and IHD mortality from prior meta-analyses for each category of PA. The number of disease-specific deaths, by age and sex, were obtained from the vital registration system for the year 2010. We considered 4 categories of PA based on the metabolic equivalent tasks per minute per week (MET/minute/week): inactive, <600, ≥ 600 to <1,600 and ≥1,600. We calculated the population attributable fraction for different levels of PA by sex and age group.
Results: In Argentina, 76.5% (CI 95%; 75.8-77.7) of the total population engaged <1,600 MET/min/week (72.8% in men and 81.1% in women). This level of insufficient activity was responsible for 26% of all IHD and stroke deaths in 2010 (11,234 of 43,796 deaths; 6,013 in men and 5,221 in women). It was also responsible for 29% (7,292) of the total IHD deaths and 21% (3,942) of the total stroke deaths. Almost half of the population or 52.5% (CI 95%; 51.3-53.7) engaged <600 MET/minutes/week (48.8% in men and 55.7% in women) and this level of inactivity was responsible for 17% (7,278 of 43,796 deaths) of all IHD and stroke deaths in 2010 (3,941 in men and 3,337 in women). It was also responsible for 20% (4,907) of the IHD deaths and 13% (2,371) of the stroke deaths The impact of physical inactivity and insufficient PA was higher in women due to lower level of PA compared to men and in the individuals younger than 70 years old due to a stronger association with the outcomes (higher relative risks), especially for IHD.
Conclusions: Physical inactivity and insufficient physical activity contribute substantially to the burden of cardiovascular diseases in Argentina. Interventions to promote PA should be a priority to prevent cardiovascular disease.
