简要总结

This study evaluates the effect of vegetation cover on certain Interleukin-10 and immunoglobulinE (IgE) among children (3-5 y old). Children will either be in a kindergarten that does not have forest floor and agricultural land in the backyards, or alternatively they will be in a kindergarten that does have forest floor and agricultural land in the backyards.

详细描述

High vegetation cover is assumed to change immunoglobulinE (IgE) and interleukin-10 concentrations in blood serum. Children living in high-green kindergarten are compared with those kindergarten living utilizing backyards with a low-green cover.

结局指标

主要结局

Diversity of Gammaproteobacteria on skin.

时间窗: 28 days

Diversity of skin Gammaproteobacteria is higher in intervention arm compared to control arm and similar compared to nature-oriented arm after 28-day intervention. It will be measured at baseline and after 28-day intervention.

  • Stool bacterial community changes at phylum level(28 days)
  • TGF-beta: IL-17A ratio in serum plasma(28 days)
  • IL-17A change in serum plasma(28 days)
  • TGF-beta change in serum plasma(28 days)
  • IL-10 change in serum plasma(28 days)
  • Skin bacterial community changes at class level(28 days)
  • Skin bacterial community changes at order level(28 days)
  • Skin bacterial community changes at family level are higher in intervention than control arm(28 days)
  • Skin bacterial community changes at genus level(28 days)
  • Associations between serum plasma TGF-beta and skin microbiota changes(28 days)
  • Stool bacterial community changes at class level(28 days)
  • Stool bacterial community changes at order level(28 days)
  • Associations between serum plasma IL-10 and skin Gammaproteobacterial microbiota changes(28 days)
  • Interleukin-10 : interleukin-17A ratio in serum plasma(28 days)
