Exposure to green spaces, cardiovascular risk biomarkers and incident cardiovascular disease in older adults: The Seniors-Enrica II cohort
Highlights Higher residential greenness associates with reduced ProBNP and IL-6 in older adults. Diabetic older adults residing in greener areas show lower levels of hsTnT. An IQR increase in residential NDVI is associated with a 10% lower risk of a CVD event. Reduced traffic and improved performance contributed most to greennesś CV effects. In diabetic individuals, increased PA fosters CV benefits linked to green space.
Abstract Introduction The impact of residential green spaces on cardiovascular health in older adults remains uncertain. Methods Cohort study involving 2114 adults aged ≥ 65 years without cardiovascular disease (CVD), residing in five dense municipalities () of the Madrid region and with detailed characterization of their socioeconomic background, health behaviors, CVD biological risk factors, and mental, physical, and cognitive health. Greenness exposure was measured using the Normalized Difference Vegetation Index (NDVI) at varying distances from participants' homes. Traffic exposure, neighborhood environment, neighborhood walkability, and socioeconomic deprivation at the census level were also assessed. Serum N-terminal pro-B-type natriuretic peptide (NT-ProBNP), high-sensitivity troponin T (hs-TnT), interleukin 6 (IL-6), and Growth Differentiation Factor 15 (GDF‐15) were measured at baseline, and incident CVD events identified through electronic medical records (International Classification of Primary Care-2 codes K74, K75, K77, K90, and K92). Results After adjusting for sex, age, educational attainment, financial hardship and socioeconomic deprivation at the census level, an interquartile range (IQR) increase in NDVI at 250, 500, 750, and 1000 m around participants' homes was associated with mean differences in ProBNP of −5.56 % (95 %CI: −9.77; −1.35), −5.05 % (-9.58; −0.53), −4.24 % (-8.19, −0.19), and −4.16 % (-7.59; −0.74), respectively; and mean differences in hs-TnT among diabetic participants of −8.03 % (95 %CI: −13.30; −2.77), −9.52 % (-16.08; −2.96), −8.05 % (-13.94, −2.16) and −5.56 % (-10.75; −0.54), respectively. Of similar magnitude, although only statistically significant at 250 and 500 m, were the observed lower IL-6 levels with increasing greenness. GDF-15 levels were independent of NDVI. In prospective analyses (median follow-up 6.29 years), an IQR increase in residential greenness at 500, 750, and 1000 m was associated with a lower risk of incident CVD. The variables that contributed most to the apparent beneficial effects of greenness on CVD were lower exposure to traffic, improved cardiovascular risk factors, and enhanced physical performance. Additionally, neighborhood walkability and increased physical activity were notable contributors among individuals with diabetes. Conclusion Increased exposure to residential green space was associated with a moderate reduction in CVD risk in older adults residing in densely populated areas.
