Abstract	:	Objectives: To identify the pattern and demographic, socio-economic, and parental caregiver correlates of smart device usage, and to identify the prospective association of excessive smart device usage and addiction with lifestyles behaviors, physical fitness, and eye problems among Hong Kong adolescents. Hypothesis to be tested: Hong Kong adolescents with a better socio-economic status and higher smart device control of parental caregiver will have higher risk of excessive smart device usage. Excessive usage of smart devices will lead to unhealthy lifestyles, poor physical fitness, and eye problems. Design and subject: A prospective study with 1-year follow-up period on students studying P.3-P.5 and S.1-S.3 in Hong Kong. Around 15 to 20 schools will be recruited, with an estimated sample size of 2,880 students. In addition, the questionnaire will be administered after 6 months of baseline. Study instruments: Height, weight and body composition, refractive error, range of motion, hand grip strength, pinch strength, and 7-day activity monitoring with accelerometer will be measured. Main outcome measures: Smart device usage and lifestyle behaviors (physical activity, dietary habits, sleeping problem) will be assessed by self-administrated questionnaire. Physical fitness and eye problems will be measured at health examination, and will be conducted at baseline and 1-year follow-up at schools. Data analysis: Multi-level regression will be used to examine the association between demographic and socio-economic status on the pattern of smart device usage, and the association between baseline smart device usage and health outcomes. Expect results: Excessive usage of smart devices and addiction will lead to health problems.
