三年时间内，调查了全军５３个团队的疾病状况指标并研制了部队疾病状况综合评价指标和方法。首先将调查的二个方面５组１４项指标预处理使之符合正态分布；然后将各指标值转换为Ｔ标准分；第三步经逐步多元回归方程筛选指标和最优方程组合；第四步，采用计算与专家确定相结合的方法确定各评价指标的权重，确定评价公式，计算疾病状况指数（ＩＴＩＳ）。该指数由传染病发病率、总住院率和每千人日门诊率三项评价指标Ｔ标准分按０．３０、０．４６和０．２４的权重分配计算获得，计算结果可直接与标准界值比较分级，同时以一定权重参加该部队群体健康状况综合评价指数的计算。按照调查样本的疾病状况指数的百分分布将各调查单位分成五级：中等占５０％，较好和较差的各占１５％，最好和最差的各占１０％。
During the three years, the disease status indicators of 53 PLA teams were investigated and indicators and methods for comprehensive evaluation of disease status of the armed forces were developed. First of all, two groups of 14 indicators in 5 groups were preprocessed to make them normal distribution; each index value was then converted into T standard score; the third step was to select indicators and the optimal equation combination through stepwise multiple regression equation; Step, using a combination of calculation and expert determination to determine the weight of each evaluation index, determine the evaluation formula, calculate the disease status index (ITIS). The index by the incidence of infectious diseases, total hospitalization rate and the out-patient rate per 1,000 people three indicators T standard points 0.30,0.46 and 0.24 weight distribution calculated, the calculation results can be directly with the standard community Value comparison grading, at the same time with a certain weight to participate in the army health evaluation index calculation. The survey units were divided into five levels according to the percentage distribution of the disease status index of the survey sample: 50% medium, 15% good and poor, and 10% best and worst.
