Determine the occurrence of asthma in the villages of the marginal areas of Lake Urmia
Abstract
Introduction: Asthma is a chronic respiratory tract inflammatory dysfunction, despite effective therapeutic approaches, can lead to death in the absence of control. 5% of the world's population has asthma. The incidence of this disease in Iran is an average of 5 to 7 The goal of this study was to calculate the incidence of asthma in the marginal lakes of Urmia Lake and compare them with different levels that can determine the impact of the Uremia Lake on the incidence of asthma in this area.
Materials and Methods: This is a retrospective cohort study that has been conducted during 10 years (1394-1385) to investigate the occurrence of asthma, which is from the year 85, which is almost simultaneously with the decrease of Lake Urmia water level, and until the year 94. This study It was carried out at three levels (Region). Region 1: Includes villages with a short distance from the lakes of villages, Ghezel Dizaj, Mayan olya , Mayan-sofla, Kajabad from Tabriz and Sary village from the city of Osku, Region 2: Includes a village with an average distance from the lake Village of Dizaj Lilikhani from Tabriz city. Region 3: Includes villages with large distances from Lake Urmia, villages, Basil, Kukhalagh, Kurdler And Frost, from the city of Ahar.
Results: The total population of the study population was 23787 people, of which 17,983 (75.6%) were from region 1 and 3107 (13.66%) were from region 2 and 2697 (11.44%) were from region 3. A total of 219 cases of asthma were extracted and documented from family physicians, which after calculating the rate of cumulative incidence in the region of 1, 10.12 per 1000 in ten years, and the rate of cumulative incidence in the region 2, 5.47 in the 1000 population In 10 years, and the rate of cumulative incidence in the region 3, which was 7.04 per 1,000 in ten years. Comparing the rate of cumulative incidence of asthma in region 1 compared to the region 2, the relative risk with the confidence of Nospopen: (1.12-2.98 )equal to 1.83 or Otherwise, the incidence of asthma in the region1 is 83% higher than that of region 2. In comparison, the rate of cumulative incidence of asthma in region 1 with region 3, the relative risk with a 95% confidence interval (1 .0 5-2.02) equal to 1. 53 Obtained. Or, among other things, the incidence of asthma in the region1 is 53% higher than that of region 3, and also comparing region two with the region of three relative risks with a confidence interval of ninety-five percent: (0.3-1.33) was 0.7.
Comparison of incidence rates between region 1 and 2 in people under 40 years of age with a confidence interval of 90% was: (0.57-2.59) relative risk equal to 56.1, which is not significant, But the area 1 and area 3 that were far apart showed a relative risk of developing asthma in people under 40 years of age.Significantly increased this risk with a confidence interval of 90%: (5.65-7.68) is equal to
With 6.7, that is, The relative risk of developing asthma in Region 1 is 6.7 times higher than that of Region 3 in people under 40 years of age, as well as comparing the incidence of asthma in the region
2 and 3 in subjects under 40 years of relative risk of developing asthma with a confidence interval of ninety-five percent (-3-5) equal to 3.97, which is meaningful). In other words, the risk of developing asthma in people under 40 in the region of two 3.97 times more than those under age 40 in Region 3.
Conclusion: Urmia Lake has a risk of developing asthma in residents The villages of the lake (District 1) have increased 0.83 to the villages of the region2 and 0.53 to the villages of the area region3, and the Urmia Lake also increased the risk of early onset of asthma Groups under the age of forty years, so that this risk is twice as high as the region2, 1.56 and 6.7 times more than that of the region3, and the risk of early onset of asthma in the second region is 3.97 times higher than that of the region3.
Of course, due to the effects of other factors on the occurrence and recurrence of symptoms of asthma, further studies are needed. Also, according to the findings of this study and the probability of the lake's impact on other aspects of the health of the inhabitants of the area, it is imperative that reputable provincial and provincial authorities consider restoration of the lake before they can be overworked.
