[Purpose] To examine the relationship between body height development and refractive error (RE) change in school-age children.
[Subjects and Methods] In 1261 eyes of 642 children who “detailed visual acuity test” between elementary-school Grade 1 to junior-high-school Grade 2 from 2016 to 2019, changes in RE was examined by binocular open-field autoref keratometer under non-accommodated paralysis and spherical equivalence was calculated. Body height data was obtained from questionnaire responses. Grade and gender was classified into 14 groups. The relationship between RE change and body-height change in each group was examined.
[Results] A significant correlation was found between RE change and body-height change in Grade 6 elementary to Grade 1 junior high school boys (r = −0.27, p = 0.005) and Grade 4–5 elementary school girls (r = −0.32, p = 0.003).
[Conclusion] Correlation between RE change and body height was found in upper-grade-elementary to junior-high boys and middle to upper-grade-elementary girls.
