Abstract
Occupational exposures are one of the major causes of chronic respiratory symptoms and illnesses, where farming and its related activities make a significant contribution, especially in low- and middle-income countries such as Pakistan.
This study aimed to estimate burden of chronic respiratory symptoms and illnesses among farmers and to identify associated factors.
A translated version of American Thoracic Society Division of Lung Disease questionnaire (ATS-DLD-78A) was used among 381 farmers in Thatta District, Pakistan in 2011. Logistic regression analysis was used to assess the association between socio-demographic and occupational risk factors and respiratory illnesses.
Chronic wheeze was reported in 65.9% of farmers exposed to pesticides compared to 34.1% of farmers not exposed (P-value: 0.10). Frequencies of other health events were almost similar among the two groups. On multivariable logistic regression analysis every 5 year increase in age of the farmer increased the risk of having respiratory illnesses by 18% (Adjusted OR [AOR]: 1.18; 95% CI: 1.03-1.35). Each 1000 Pakistani Rupees (PKR) increase in household income increased the risk of having respiratory illnesses by 10% (AOR: 1.10; 95% CI: 1.01-1.25).
Occupational Health and safety is a neglected area in many parts of the country especially when it comes to farmers. This study highlights the importance of factors other than pesticides impacting the respiratory health of the farmers, emphasizing on those who smoke tobacco.
