The Calculating Trial On Health Expectancy Of Beijing Residents

BackgroundLife expectancy has traditionally been used as a indicator of population health status，however it takes no account of the quality of life and just measures the number ofremaining years to be lived. It is no longer sufficient to focus on the duration oflifespan but quality of life should be considered to measure progress of populationhealth. Health expectancy is the representative summary measure of population healthindicator that combine mortality and morbidity or other non-fatal health outcomeinformation together, it adds a quality of life dimension to estimates of lifeexpectancy by dividing predicted lifespan into time spent in given states of health.Life expectancy at birth in Beijing has risen slow down and entered a steadilyincreasing plateau after reaching80years in2008, it’s also not as much sensitive tohealth change of the residents as it was before. To measure progress of populationhealth scientifically and reasonably in Beijing, conduct health expectancy calculationof residents and relevant research would be helpful.ObjectivesBased on available data from health information system of the Beijing MunicipalHealth Bureau, choose the common used health expectancy indicators according toliterature review and calculate for residents in Beijing. To evaluate the indicators andcalculation method as well as use them measure the residents health status. Researchadvice and policy proposal for the domestic practice of health expectancy will begiven finally. MethodsThe study is based on the data from regular statistic survey and special statistic surveyof Beijing Municipal Health Bureau. The former included annually official populationand mortality data, the later included4thNational Health Service Survey and2ndNational Sample Survey on Disability.According to the result of literature review and expert consultation we selectedseveral suitable health expectancy indicators. The abridged life table and Sullivan’smethod was used to calculate health expectancies. Descriptive analysis was carriedout for presenting outline of the indicators and time trend of different age-band.Chi-square test was used to compare the proportions or rates among differentsubgroups. Z-Statistic was used to test the equality of health expectancies betweendifferent gender groups. From data collection to statistical analysis, the whole workswere accomplished by IBM SPSS Statistic software.ResultsHealth expectancy could be subdivided into two main classes：health state expectancy（HSE）and health-adjusted life expectancy（HALE）.Life expectancy in goodself-perceived healt（hHE-sp）,Disability-free life expectanc（yDFLE）,Life expectancywithout chronic morbidity（HE-cm）are three common reported health expectancies inpractice.In2008, HE-sp at birth for residents in Beijing was72.75years, for male and femalewas71.22years and73.89years respectively. The proportion of HE-sp in a total LEfor male was higher than female（Z=2.11，＜0.05）.DFLE for the residents at birthwas75.18years，male at birth was73.85years and female at birth was76.56years;The proportion of DFLE in LE for each age-band before at80years of age for malewas slightly higher than female, however after80years of age the difference reversed.HE-cm for the residents at birth was62.73years, for male and female was61.87 years and63.75years respectively; The proportion of lifespan with chronic morbidityof remaining life for the male aged over65years was higher than female of the sameage. Generally speaking, for all the health expectancies of life expectancies, maleuniversally spent a greater proportion than female, but in the aged groups thedifference reversed.ConclusionsHealth expectancy is a suitable indicator to measure health status of population.Coherent data resource and collection method is the foundation of health expectancycalculation and application. For the male residents in Beijing their quality of lifeduring the whole lifespan was higher than female. The quality of life for the agedmale residents in their remaining life may be lower than female.We propose four proposals as following: Promoting the government use healthexpectancy as the important indicator for residents’ health status evaluation andfacilitating the consolidation and utility of population data relevant to the residents’full lifecycle information. The government should establishing domestic informationreport and data collection mechanism reference abroad mature experience andconsidering the long-term care demand as well as its sustainable system constructionof the elderly residents.
