HIV/AIDS is one of the pressing public health problems in India. Available information indicates a rising trend of infection. The impact of HIV/AIDS on the economic front is important as it affects mainly the young, who are in the reproductive age group. We estimated the cost of productivity losses in a lifetime attributable to HIV-related mortality in India in the population of the year 1991 at current HIV infection rates.
The analysis was done from the societal viewpoint, adopting a discount rate of 5%. To estimate the loss in person-years due to HIV/AIDS, two scenarios were considered. Firstly, the population without HIV/AIDS, and secondly, the population with HIV/AIDS. The difference in person-years lived by the cohort in both populations would provide the person-years lost due to HIV/AIDS. To calculate the person-years lived in each, the life table approach was used. The demographic data from the 1991 Census were used. The population was divided into 15 five-year cohorts and the current age-specific death rates were used. Assumptions regarding HIV incidence rates in urban and rural areas in different age groups were made based on the available data and consensus of experts. The estimate was first done for a cohort of 100,000 population for rural and urban areas and then extrapolated to the population in the different age groups. To convert the person-years lost into monetary terms, minimum wages were estimated to be Rs 14,460 per annum.
The total undiscounted life-years lost due to HIV/ AIDS by the present population of India will be 238.4 million years-123.7 million years for urban and 114.7 million years for rural areas. On an average this is 0.4 years lost per person. The life-years lost per case of HIV was 44.4 years. Assuming minimum wages of Rs 14460 as the value of one year, the total economic loss is Rs 3447 billion. The productivity loss per case is Rs 642,024 (US$ 20,710). For an estimated national per capita income of Rs 4252.4 the total economic loss is Rs 1014 billion. If a discount rate of 5% is applied for future losses then the total potential years of life lost will be 23 million-11.3 million for urban and 11.7 million for rural areas. In monetary terms this will be Rs 332.6 billion by minimum wages assumption, and 97.8 billion if the national per capita income is assumed to be the cost of one year.
HIV/AIDS imposes a significant burden on the economic front. The productivity losses are likely to be an underestimate as the costs of treatment of HIV/AIDS patients, prevention programmes and labour costs have not been taken into account. To decide whether HIV/AIDS needs a high priority int he Indian context, it is necessary to have similar estimates for other important diseases such as tuberculosis and cancer.
艾滋病毒/艾滋病是印度紧迫的公共卫生问题之一。现有信息表明感染呈上升趋势。艾滋病毒/艾滋病对经济领域的影响很重要,因为它主要影响处于生育年龄组的年轻人。我们按照1991年的艾滋病毒感染率估算了印度因艾滋病毒相关死亡导致的一生生产力损失成本。
分析从社会角度进行,采用5%的贴现率。为估算因艾滋病毒/艾滋病导致的人年损失,考虑了两种情况。其一,无艾滋病毒/艾滋病的人群;其二,感染艾滋病毒/艾滋病的人群。这两组人群中同队列所活的人年差异将得出因艾滋病毒/艾滋病导致的人年损失。为计算每组人群所活的人年,采用了生命表方法。使用了1991年人口普查的人口统计数据。将人口分为15个五岁年龄组,并使用当前的年龄别死亡率。根据现有数据和专家共识,对不同年龄组城乡地区的艾滋病毒发病率进行了假设。首先对城乡地区10万人口的队列进行估算,然后推算到不同年龄组的人口。为将人年损失换算成货币价值,估计最低工资为每年14,460卢比。
印度当前人口因艾滋病毒/艾滋病导致的未贴现总生命年损失为2.384亿年——城市地区为1.237亿年,农村地区为1.147亿年。平均每人损失0.4年。每例艾滋病毒感染者的生命年损失为44.4年。假设最低工资14,460卢比为一年的价值,总经济损失为34,470亿卢比。每例的生产力损失为642,024卢比(20,710美元)。对于估计的人均国民收入4,252.4卢比,总经济损失为10,140亿卢比。如果对未来损失应用5%的贴现率,那么潜在生命年总损失将为2300万年——城市地区为1130万年,农村地区为1170万年。按最低工资假设,货币价值将为3326亿卢比;若假设人均国民收入为一年的成本,则为978亿卢比。
艾滋病毒/艾滋病给经济领域带来了重大负担。由于未考虑艾滋病毒/艾滋病患者的治疗成本、预防项目和劳动力成本,生产力损失可能被低估。要确定在印度背景下艾滋病毒/艾滋病是否需要高度优先关注,有必要对结核病和癌症等其他重要疾病进行类似估算。
