論 文 内 容 の 要 旨

This research utilized prospective data from a large mental health study conducted on first-year university students in Kyushu University, the EQUSITE Study (Enhancement of Q-University Students Intelligence Study). Data were drawn from the baseline survey of the freshmen who enrolled in Kyushu University in 2010.

Firstly, a cross-sectional study involving 2, 036 freshmen was conducted to examine the association between the sense of coherence (SOC) and relationship with parents and close friends with a wish to die. The analyses were conducted using multiple logistic regression. Results indicated that higher SOC was associated with lower odds of having a wish to die, independent of depressive symptoms and other relevant confounding factors. Having a good relationship with parents and absence of close friends were respectively associated with lower and higher odds of having a wish to die.

Secondly, another cross-sectional study was conducted among 2,000 freshmen, which included freshmen aged between 18 to 20 years old. This study examined the relationship between a wish to die with perceived overweight and actual weight (measured by Body Mass Index) in the freshmen using multiple logistic regression analyses. Results indicated a wish to die prevalence of 5.8% (n=115) and perceived overweight prevalence of 15.8% (n=315). Perceived overweight significantly increased the odds of a wish to die by two-fold. Actual weight was not significantly correlated with a wish to die.

To conclude, this research has contributed to the understanding of a wish to die during the period of young adulthood. In light of the increasing suicide cases among university students in Japan year by year, this research provided insights into several psycho-social modifiable factors that may be used by university clinicians particularly, to design suicide prevention programs. This research indicated that freshmen who presented with low scores of SOC, have poor relationships with parents, have no close friends, and who perceived themselves as overweight have higher likelihood of having a strong desire to die.

Additionally, these findings have important implications for mental health

professionals treating young adults and prevention programming aimed at reducing

the desire to die and to reduce progression towards suicidal ideation.
