The Association Of Sleep Quality And Suicidal Ideation Among The Elderly In Shandong,China

Research BackgroundSleep is very important,if we don't sleep well,it will damage our health.With the increase of age,the elderly's sleep quality will decrease.With the decline of sleep quality,the elderly's memory and cognitive function will be impaired,too.Moreover,it will even lead to depression and anxiety.With the aging of the society,the cardinal number of the elderly in our society is very large.Thus,the sleep problems of the elderly should be valued.Aging of population has brought another problem which is seniors' suicide.At present,the highest suicide rate of population is among seniors,which should pay attention to.Some studies find that seniors aged 65 or above have the highest rate of suicide behavior,which reaches 44.3-200 per 100,000 in China.Suicidal ideation is the prelude of suicide.People with suicidal ideation are the ones who have considered suicide but don't take actual suicidal behavior.The next move of suicidal ideation is suicide behavior,thus,it's very important to study it.We have to know clearly how suicidal ideation comes into being,and find its risk factors to prevent suicide.Some studies indicate that sleep quality is associated with suicidal ideation.However,past studies mainly focus on teenagers instead of seniors.Thus,it's very necessary to examine the association of sleep quality and suicidal ideation among seniors.ObjectiveWe try to find out the current situation of sleep quality and its components and analyze their risk factors.We try to find out status quo of suicidal ideation and its risk factors.Our study tries to find out the association of suicidal ideation and sleep quality.Relevant suggestions are made as reference to decrease suicidal ideation among seniors.MethodsWe randomly selected 3313 seniors aged 60 or above as study participants in Shandong province.Questionnaires are used to obtain data of suicidal ideation and sleep quality.Epidata is used for data entry,SPSS 21.0 is used for data analysis.Student's t-tests and chi-square tests were used for univariate analysis.Binary logistic regression and multiple linear regression are used for multivariate analysis.Binary logistic regression with an enter method and multiple linear regression were employed to assess the association between suicidal ideation and sleep quality.ResultsSeniors with different kinds of chronic diseases(P=0.000)and psychological status(P=0.000)are significantly different between sleep quality,sleep latency,sleep duration,sleep disturbances and daytime dysfunction.Seniors with different marital status(P=0.004),different kinds of chronic diseases(P=0.000)and psychological status(P=0.000)are significantly different between subjective sleep quality.Seniors with different psychological status(P=0.000)are significantly different between habitual sleep efficiency.Seniors with middle school education(P=0000),normal(P=0.000)and good(P=0.000)self-rated economic status have lower rates of suicidal ideation.Those seniors who have 2 chronic diseases(P=0.016)and 3 chronic diseases(P=0.006)and severe dysfunction(P=0.000)have higher suicidal ideation.Sleep quality and suicidal ideation is significantly correlated(OR=1.264 95%CI 1.193-1.339),seniors' subjective sleep quality(OR=2.030 95%CI 1.335-3.086),sleep efficiency(OR=0.669 95%CI 0.471-0.952)and daytime dysfunction(OR=2.16995%CI 1.695-2.774)are also correlated with suicidal ideation.ConclusionDifferent kinds of chronic diseases are significantly different between sleep quality,subjective sleep quality,sleep latency,sleep duration,sleep disturbances and daytime dysfunction.Sleep quality,subjective sleep quality,sleep latency,sleep duration,sleep disturbances,daytime dysfunction and habitual sleep efficiency are significantly correlated with psychological status.Marital status is also significantly correlated with subjective sleep quality.Risk factors of suicidal ideation are education,seff-rated economic status,kinds of chronic diseases and ADL.Sleep quality and suicidal ideation is significantly correlated.Sleep-based interventions should be developed to prevent suicide in older adults in China.
