higher prevalence of poor (vs. favorable) sleep health with less greenspace
Exact: 12% higher prevalence
Low/moderate greenspace was associated with a 12% higher prevalence of poor sleep health compared to favorable sleep health
Beyond the moderate sleep category, women with less residential greenspace were also more likely to fall into the poor sleep health category. The adjusted prevalence ratio of 1.12 indicates a meaningful and statistically significant association, suggesting that greenspace deprivation is linked to the most adverse sleep outcomes as well.
low/moderate vs. high greenspace was associated with a 32 % higher prevalence of moderate (PR = 1.32 [1.27-1.38]) and 12 % higher prevalence of poor (PR = 1.12 [1.07-1.16]) vs. favorable sleep health.
