The author analyzes the level and structure of morbidity of respiratory system diseases among the rural population, according to age--sex groups on the base of the data from routine statistics (1970-1978) and typological studies of general morbidity carried out in Sliven district (1977). The complex methodics applied allowed to study the morbidity according to repeated visits (registered) and that, established at the prophylactic screening (latent) of a representative sample of the population under observation. The results from that study revealed that the actual morbidity (registered according to visits and established with the complex medical screening) of the respiratory system diseases, among rural population is 625,7%. Morbidity among males is higher (664,2%) than that of females (570,3%). Highest is the morbidity among subjects over the age of 60 and among children (0-14 years).
作者根据常规统计数据（1970 - 1978年）以及在斯利文地区开展的一般发病率类型学研究（1977年），按年龄 - 性别组分析了农村人口呼吸系统疾病的发病水平和结构。所采用的综合方法能够依据复诊（登记）情况以及在对观察人群代表性样本进行预防性筛查（潜在发病情况）时所确定的情况来研究发病率。该研究结果显示，农村人口呼吸系统疾病的实际发病率（根据就诊登记以及综合医学筛查确定）为625.7%。男性的发病率（664.2%）高于女性（570.3%）。60岁以上人群以及儿童（0 - 14岁）的发病率最高。
