A Comprehensive Health Profile of Youths Living

To understand the health impacts of “hikikomori” lifestyle and to establish its first 16 comprehensive health profile, a cross-sectional study was designed to measure how well the cases 17 of hikikomori youths of Hong Kong were living, in terms of social, mental and physical aspects. 18 This study involved 104 eligible participants at age 19.02 year-old who had completed the set of 19 questionnaires and a series of anthropometric and physical health measurements. Despite SF36 20 score of 84.0 indicated good physical functioning in general, participants were lived sedentarily 21 with high incidence of hypertension at 15.4% and prehypertension at 31.7%. Occurrence of 22 hypertension in cases living as hikikomori >6 months was 3-times higher than those newly onset 23 cases. The blood pressure levels were correlated with age and all obesity index parameters 24 measured including waist circumference and body mass index. Half of the hypertensive cases 25 involved the elevation of systolic blood pressure, which suggested higher odds of cardiovascular 26 complications. Participants were mentally stable living with moderate levels of perceived stress and 27 state anxiety, but borderline clinical depression. In conclusion, the hikikomori lifestyle could be a 28 risk behavior that may harm the younger generation physically by promoting obesity and 29 hypertension and probably other chronic illnesses. 30
