Relationship between axial length (AL) and lifestyle. The hours of the indoor studying (r = −0.06, P = 0.55), television viewing (r = −0.12, P = 0.19), outdoor activities (r = 0.04, P = 0.67), and bedtime (r = −0.13, P = 0.17) were not significantly correlated with the AL a, b, d, e. The duration of computer and smartphone use (r = 0.24, P = 0.008), westernized dietary habits (r = −0.24, P = 0.01), and parental myopia (r = 0.39, P < 0.001) were significantly correlated with the AL c, f, g. Only westernized dietary habits was significantly correlatated with the BMI (r = −0.27, P = 0.003) h although other factors were not
