Physical Activity and Stroke Risk: A Meta-Analysis

Background and Purpose - Whether physical activity reduces stroke risk remains controversial. We used a meta-analysis to examine the overall association between physical activity or cardiorespiratory fitness and stroke incidence or mortality. Methods - We searched MEDLINE from 1966 to 2002 and identified 23 studies (18 cohort and 5 case-control) that met inclusion criteria. We estimated the overall relative risk (RR) of stroke incidence or mortality for highly and moderately active individuals versus individuals with low levels of activity using the general variance-based method. Results - The meta-analysis documented that there was a reduction in stroke risk for active or fit individuals compared with inactive or unfit persons in cohort, case-control, and both study types combined. For cohort studies, highly active individuals had a 25% lower risk of stroke incidence or mortality (RR=0.75; 95% CI, 0.69 to 0.82) compared with low-active individuals. For case-control studies, highly active individuals had a 64% lower risk of stroke incidence (RR=0.36; 95% CI, 0.25 to 0.52) than their low-active counterparts. When we combined both the cohort and case-control studies, highly active individuals had a 27% lower risk of stroke incidence or mortality (RR=0.73; 95% CI, 0.67 to 0.79) than did low-active individuals. We observed similar results in moderately active individuals compared with inactive persons (RRs were 0.83 for cohort, 0.52 for case-control, and 0.80 for both combined). Furthermore, moderately and highly active individuals had lower risk of both ischemic and hemorrhagic strokes than low-active individuals. Conclusions - We conclude that moderate and high levels of physical activity are associated with reduced risk of total, ischemic, and hemorrhagic strokes

Prospective study of lung function and abdominal aortic aneurysm risk: The Atherosclerosis Risk in Communities study

Abstract Background and aims No prospective study has investigated whether individuals with respiratory impairments, including chronic obstructive pulmonary disease (COPD) and restrictive lung disease (RLD), are at increased risk of abdominal aortic aneurysm (AAA). We aimed to prospectively investigate whether those respiratory impairments are associated with increased AAA risk. Methods In 1987–1989, the Atherosclerosis Risk in Communities (ARIC) study followed 14,269 participants aged 45–64 years, without a history of AAA surgery, through 2011. Participants were classified into four groups, “COPD” [forced expiratory volume in 1 s (FEV1)/forced vital capacity (FVC) <lower limit of normal (LLN)], “RLD” (FEV1/FVC ≥ LLN and FVC < LLN), “respiratory symptoms with normal spirometry” (without RLD or COPD), and “normal” (without respiratory symptoms, RLD or COPD, reference group). Results During the 284,969 person-years of follow-up, 534 incident AAA events were documented. In an age, sex, and race-adjusted proportional hazards model, individuals with respiratory impairments had a significantly higher risk of AAA than the normal reference group. After adjustment for AAA risk factors, including smoking status and pack-years of smoking, AAA risk was no longer significant in the respiratory symptoms with normal spirometry group [HR (95% CI), 1.25 (0.98–1.60)], but was still increased in the other two groups [RLD: 1.45 (1.04–2.02) and COPD: 1.66 (1.34–2.05)]. Moreover, continuous measures of FEV1/FVC, FEV1 and FVC were associated inversely with risk of AAA. Conclusions In the prospective population-based cohort study, obstructive and restrictive spirometric patterns were associated with increased risk of AAA independent of smoking, suggesting that COPD and RLD may increase the risk of AAA. Highlights • No prospective study has examined the association between lung function and abdominal aortic aneurysm (AAA). • We examined this association using a prospective population-based study in the US. • Chronic obstructive pulmonary disease (COPD) and restrictive diseases patterns were associated with increased AAA risk. • This study suggested COPD and restrictive lung diseases may increase AAA risk

Greater Adherence to Life's Simple 7 Is Associated With Less Arterial Stiffness: the Atherosclerosis Risk in Communities (ARIC) Study

BACKGROUND: Greater arterial stiffness is associated independently with increased cardiovascular disease risk. The American Heart Association (AHA) has recommended following "Life's Simple 7 (LS7)" to optimize cardiovascular health; we tested whether better LS7 in middle age is associated with less arterial stiffness in later life. METHODS: We studied 4,232 black and white participants aged 45-64 years at the baseline (1987-89) visit of the Atherosclerosis Risk in Communities Study cohort who also had arterial stiffness measured in 2011-13 (mean ± SD interval: 23.6 ± 1.0 years). We calculated a 14-point summary score for baseline LS7 and classified participants as having "poor" (0-4), "average" (5-9), or "ideal" (10-14) cardiovascular health. We used logistic regression to calculate odds ratios (ORs) and 95% confidence intervals (95% CI) for arterial stiffening: a high carotid-femoral pulse wave velocity (cfPWV, ≥13.23 m/s) or a high central pulse pressure (central PP, ≥ 82.35 mm Hg). RESULTS: The age, race, sex, and heart rate-adjusted ORs (95% CI) for high cfPWV in the "ideal," "average," and "poor" LS7 summary categories were 1 (Reference), 1.30 (1.11, 1.53), and 1.68 (1.10,2.56), respectively (P-trend = 0.0003). Similarly, the adjusted ORs (95% CI) for high central PP across LS7 summary categories were 1 (Reference), 1.48 (1.27, 1.74), and 1.63 (1.04, 2.56), respectively (P-trend &lt;0.0001). CONCLUSION: Greater LS7 score in middle age is associated with less arterial stiffness 2-3 decades later. These findings further support the AHA recommendation to follow LS7 for cardiovascular disease prevention

Association of Educational Attainment With Lifetime Risk of Cardiovascular Disease: The Atherosclerosis Risk in Communities Study

Estimates of lifetime risk may help raise awareness of the extent to which educational inequalities are associated with risk of cardiovascular disease (CVD). To estimate lifetime risks of CVD according to categories of educational attainment. Participants were followed from 1987 through December 31, 2013. All CVD events (coronary heart disease, heart failure, and stroke) were confirmed by physician review and International Classification of Diseases codes. A total of 13 948 whites and African Americans who were 45 to 64 years old and free of CVD at baseline were included from 4 US communities (Washington County, Maryland; Forsyth County, North Carolina; Jackson, Mississippi; and suburbs of Minneapolis, Minnesota). The data analysis was performed from June 7 to August 31, 2016. Educational attainment. We used a life table approach to estimate lifetime risks of CVD from age 45 through 85 years according to educational attainment. We adjusted for competing risks of death from underlying causes other than CVD. The sample of 13 948 participants was 56% female and 27% African American. During 269 210 person-years of follow-up, we documented 4512 CVD events and 2401 non-CVD deaths. Educational attainment displayed an inverse dose-response relation with cumulative risk of CVD, which became evident in middle age, with the most striking gap between those not completing vs completing high school. In men, lifetime risks of CVD were 59.0% (95% CI, 54.0%-64.1%) for grade school, 52.5% (95% CI, 47.7%-56.8%) for high school education without graduation, 50.9% (95% CI, 47.3%-53.9%) for high school graduation, 47.2% (95% CI, 41.5%-52.5%) for vocational school, 46.4% (95% CI, 42.8%-49.6%) for college with or without graduation, and 42.2% (95% CI, 36.6%-47.0%) for graduate/professional school; in women, 50.8% (95% CI, 45.7%-55.8%), 49.3% (95% CI, 45.1%-53.1%), 36.3% (95% CI, 33.4%-39.1%), 32.2% (95% CI, 26.0%-37.3%), 32.8% (95% CI, 29.1%-35.9%), and 28.0% (95% CI, 21.9%-33.3%), respectively. Educational attainment was inversely associated with CVD even within categories of family income, income change, occupation, or parental educational level. More than 1 in 2 individuals with less than high school education had a lifetime CVD event. Educational attainment was inversely associated with the lifetime risk of CVD, regardless of other important socioeconomic characteristics. Our findings emphasize the need for further efforts to reduce CVD inequalities related to educational disparities
