Investigation of guidance on maintaining visual acuity at combined school from kindergarten to junior high school.: Consideration of relationship between visual acuity and lifestyle

The negative effect of visual acuity for growing children led by widely use of IC device such as mobile phone is concerned today. Heavy use of electronic device such as PC in early age will bring poor visual acuity, and an inconvenience in exercise caused by wearing glasses. In this study, we used wearable devise to search relations between daily lives of children and a decrease in vision in add to a preexisting questionnaire. Compared with the duration of watching TV and reading books of PVA( Poor visual acuity) and NPVA(Non poor visual acuity), PVA students were turned out to be using more time in doing, which supports previous studies. The relevance to visual acuity and sleep was clarified to be significantly shorter in NPVA in terms of nocturnal awakening, and also the average of a sleep and a deep sleep duration were longer in NPVA. No significant difference was observed due to the small parameter. From now on, the further work is needed to examine child's sleep conscientiously, including enriching health guidance for sight maintenance

Identification of Factors Influencing Cholesterol Changes in Elementary-School Children: A Longitudinal Study

Changes in serum cholesterol levels during childhood may affect the risk of cardiovascular disease in adulthood. However, cholesterol level changes in Japanese children and adolescents and the factors that influence them have not been completely elucidated. This study aimed to determine whether cholesterol levels changed due to the effects of growth and identify factors. This cohort study included elementary-school children in the fourth grade (9–10-year-old) who underwent assessments of cholesterol levels and demographic and lifestyle characteristics. The participants were followed up in their first year of junior high school with the same laboratory, demographic, and lifestyle assessments. From the fourth year of elementary school to the first year of junior high school, children’s cholesterol levels decreased (p p < 0.001). The study demonstrated the significance of lifestyle factors for growth-related changes of total cholesterol levels and identified weight as the factor that most strongly influenced total cholesterol level changes. Guidance regarding lifestyle improvements should be imparted to children from the fourth grade of elementary school

However, cholesterol level changes in Japanese children and adolescents and the factors that influence them have not been completely elucidated. This study aimed to determine whether cholesterol levels changed due to the effects of growth and identify factors. This cohort study included elementary-school children in the fourth grade (9&ndash;10-year-old) who underwent assessments of cholesterol levels and demographic and lifestyle characteristics. The participants were followed up in their first year of junior high school with the same laboratory, demographic, and lifestyle assessments. From the fourth year of elementary school to the first year of junior high school, children&rsquo;s cholesterol levels decreased (p &lt; 0.0001). Regarding bowel movements, cholesterol level reduction was significant in individuals with regular bowel movements but not significant in those with infrequent bowel movements. Weight was the factor that most strongly negatively predicted cholesterol level reduction (p &lt; 0.001). The study demonstrated the significance of lifestyle factors for growth-related changes of total cholesterol levels and identified weight as the factor that most strongly influenced total cholesterol level changes. Guidance regarding lifestyle improvements should be imparted to children from the fourth grade of elementary school
