The initial age of observation is 6\u201310\u2009years, and they will be observed until they graduate from high school (&amp;gt;18\u2009years of age). (1) Targeted diseases: The growth rates of myopia, obesity, and high blood pressure vary by regions, and for developed regions, the prevalence of myopia, obesity, and elevated blood pressure is 29.2%, 17.4%, and 12.6% in the first year, respectively. For developing regions, the prevalence of myopia, obesity, and elevated blood pressure is 22.3%, 20.7%, and 17.1% in the first year, respectively. The average score of CES-D is 12.9\u2009\u00b1\u20099.8 in developing regions\/11.6\u2009\u00b1\u20099.0 in developed regions.

Exposure factors include three aspects: (1) individual behaviors, (2) environment and metabolomics, and (3) gene and epigenetics.
