Journal Title: International Journal of Preventive, Curative & Community Medicine - Year 2018, Vol 4, Issue 2
Abstract
Background: According to a WHO study, 13 of the 20 most-polluted cities in the world are in India, which is more than half of the world’s most polluted cities. Delhi is at 11th position. Pollution in Delhi hit almost 30 times the WHO safe limit. On 8th Nov 2017, toxic smog enveloped Delhi, which alarmed the Indian Medical Association (IMA) to declare a public health emergency. They also advised citizens to stay indoors and schools to be shut. Air Quality Index (AQI) of neighboring Faridabad, Ghaziabad, Noida, and Gurgaon were also in the emergency category. Aim: To assess perception on air pollution and the willingness to contribute to control air pollution among the general population of Delhi. Methodology: A community-based cross-sectional study, in seven localities of South Delhi district of Delhi using simple random sampling. 384 adult members (>18 years) residing in the selected households for more than 6 months and who volunteered for the study were recruited. The sample size was calculated using Epiinfo software version 7.2.2.2 (developed by CDC). A pre-tested semi-structured interviewer-administered questionnaire was used for data collection. Ethical clearance was obtained from administrative authorities and institutional ethical committee. Data was analyzed using a SPSS 21. Results: Among 384 participants, 57.6% believed that the current air quality was worse than it was 5 years ago. People with high income (31.4%) perceived fewer symptoms due to current air quality. More men (61%) perceived air quality to be worse, but women perceived symptoms of air pollution more. Less-educated residents are the targetable population for improving environment. Regarding willingness to contribute for control of air pollution, all the positive questions received a median score of 4 or 5 (on a Likert scale of 1–5, where 1 is strongly disagree and 5 is strongly agree).
