Complete data on blood lipids (total cholesterol, HDL, LDL and triglyceride), residential greenness (NDVI in 100-m, 300- and 500-m buffers around residences) and confounders were available for 1,552 participants at 10 and 15 years of age, residing in two study areas of two German birth cohorts – GINIplus and LISAplus. Longitudinal associations between NDVI and blood lipids were assessed by generalized estimation equations.
No associations were observed between residential greenness in any of the chosen buffers and blood lipids in children (e.g., change in blood lipids per interquartile increase in NDVI in 100-m buffer for total cholesterol and LDL: means ratio=1.00 (95% confidence interval: 0.99–1.01), for triglyceride: 0.98 (0.96–1.00)). No area- or sex-varying effects were evident. Change of the residence between 10 and 15 years also did not yield any consistent associations.
There is no evidence of an association between greenness and blood lipids in 10- and 15-years old children.
