Comparing residents perceived health status in relation to Air Pollutant Index (API) : case study for Shah Alam and Putrajaya / Nor Hazlina Mohammad

| Summary: | Most studies on air pollution are focused on forecasting Air Pollutant Index (API) and yet there
seems to be no studies that conducted in Malaysia that is focused on Health-Related Quality of
Life (HRQoL). This study has been conducted to investigate the HRQoL in two cities in
Selangor, Shah Alam and Putrajaya with different air pollution index. The study utilised the
SF36v2 questionnaire which elicits data on HRQoL domains measured using eight domains
(Physical Functioning, Role-Physical, Bodily Pain, General Health, Vitality, Social Functioning,
Role-Emotional and Mental Health). The initial study of this research was to determine air
pollution trends between years 2000 to 2011. Then, this study not only compared the air
pollutant index (API) but also it compared the HRQoL scores between the residents of the two
cities. It thus investigated how air pollution affects the human health quality of life. A crosssectional
study was conducted and residents were selected using simple random sampling from
Shah Alam and Putrajaya. The SF36v2 questionnaire with socio demographic information was
distributed to the residents within four weeks. A total of 266 participated in the study, of which
133 samples per groups. Trend analysis was used to analyse Air Pollutant Index. On the other
hand, descriptive analyses, independent samples t-test and MANOVA were used to analyse the
HRQoL data. Results of the time series analysis on the air pollutant index shows that, the overall
air quality in these cities was between good to moderate level, but it shows that there is some
increase in Shah Alam and decrease in Putrajaya, over time. Meanwhile, based on HRQoL result
analysis, residents in Shah Alam shows lower HRQoL than the residents in Putrajaya.
Surprisingly, the quality of life of residents in both cities is lower than the general population
norm for all domains. |
