A total of 1597 participants (49.9% male, mean age 10.9, SD 2.0) who completed both baseline (2017-2018) and 1-year follow-up (2018-2019) eye examinations were included in the present study. The non-cycloplegic auto-refractive error was measured and the average spherical equivalent refraction (SER) was analyzed. The participants also self-reported their smart device usage at baseline. Multivariate regression adjusted for age, sex, baseline SER, parents' short-sightedness, BMI, time spent on moderate-to-vigorous physical activity (MVPA), and caregiver-reported socio-economic status showed that, compared with the reference group ( less then 2 h per day on both smartphone and tablet usages), those who spent ≥2 h per day using a smartphone and less then 2 h per day using a tablet had a significantly negative shift in refractive error (1-year change in SER -0.25 vs. -0.09 D, p = 0.01) for the right eye, while the level of significance was marginal (1-year change -0.28 vs. -0.15 D, p = 0.055) for the left eye. To conclude, our data suggested spending at most 2 h per day on both smartphones and tablets.Cervical cancer-preventive behaviors in Korean sexual minority women (SMW) are underexplored. We aimed to assess the differences in cervical cancer screening uptake and completion of human papillomavirus (HPV) vaccination among Korean SMW by sex of their sexual partners. This cross-sectional study used data from the 2017 Korean Sexual Minority Women's Health Study; we included Korean lesbian and bisexual women aged ≥20 years. They were divided into three groups SMW with more than one male sexual partner (male only/both), SMW with only female sexual partners (female-only), or no sexual partner (no partner). Among the 671 participants, 26
