An attempt has been made to estimate the gross burden of chronic obstructive pulmonary disease (COPD) and its smoking association by reviewing the population studies available from India. Of the 14 studies which were reviewed, there were 11 conducted in general populations. The median values of different prevalence rates (i.e. 5 percent in male and 2.7 percent in female population) were accepted as the most appropriate figures to calculate the overall estimates. The overall M:F ratio was 1.6:1, i.e. 61.6 percent males. The estimated total number of adult patients aged 30 years and above in 1996 were 8.15 million males and 4.21 million females. The smoker:non-smoker ratio in males was assessed at 82.3 percent with an estimated burden of 6.7 millions. When the prevalence rates of COPD and its smoking associations were assessed in three different time periods (before 1970; between 1971-1990; after 1990), the median rates of 1971-1990, when the maximum number of studies were conducted, were nearly the same as the overall rates. However, the total burden as well as the smoking associated COPD, increased with time due to an increase in the eligible base population. In conclusion, these figures can be used to estimate the burden of COPD and its smoking association in India for different statistical analyses.
通过回顾印度现有的人口研究，试图估算慢性阻塞性肺疾病（COPD）的总体负担及其与吸烟的关联。在 reviewed 的 14 项研究中，有 11 项是在普通人群中进行的。不同患病率的中位数（即男性为 5%，女性为 2.7%）被视为计算总体估计值的最合适数字。总体男女比例为 1.6:1，即男性占 61.6%。1996 年 30 岁及以上成年患者的估计总数为男性 815 万，女性 421 万。男性吸烟者与非吸烟者的比例估计为 82.3%，估计负担为 670 万。当在三个不同时间段（1970 年以前；1971 - 1990 年期间；1990 年以后）评估 COPD 患病率及其与吸烟的关联时，进行研究数量最多的 1971 - 1990 年的中位数患病率与总体患病率几乎相同。然而，由于符合条件的基础人群增加，总体负担以及与吸烟相关的 COPD 随时间增加。总之，这些数字可用于估算印度 COPD 的负担及其与吸烟的关联，以进行不同的统计分析。
