“…Season has been reported as a possible effect modifier on the association between environmental factors and respiratory morbidity in a previous local study,22 therefore the same classification of season was adopted for this study. Subgroup analyses by age group were done for older adults (aged 60 or over), working age adults (aged 15–59) and children (aged under 15).…”

“…On the other hand, in the association between meteorological parameters and health outcome, we used only lag 0 (current effects). The results of many studies [34,35] report that delayed effects (i.e., lag 3, lag 4, lag 7, lag 14 etc.) of meteorological parameters, especially temperature, could be very important for the observed health outcome.…”

Background: The aim of this study has been to examine the association between climate conditions (CC) and hospital admissions for the subcategories of cardiovascular diseases (CVD), according to patients' age. Material and Methods: From January 2010 through December 2011, the daily number of hospital admissions for angina pectoris (AP), essential hypertension (EH), acute myocardial infarction (AMI) and ischemic heart diseases (IHD) for adults (19-64 years old) and the elderly (≥ 65 years old), as well as for the CC (N = 728 days) was collected for multivariate Poisson regression analysis, confounding with season and weekends. The results were expressed by using the relative risk with the corresponding 95% confidence interval. Results: The risk for the AMI among the adults and the elderly is significantly higher for 41.8% and 38.9%, respectively on the days with lower ambient temperature and lesser for 32.7% and 29.8%, respectively on the days with lower air pressure values. The risk for the IHD among the elderly is significantly higher on the days with lower ambient temperature and lower relative humidity for 50.6% and 37.4%, respectively. Conclusions: Our findings explain how the CC and subcategories of CVD are associated, which could be used for adequate public awareness of the risk for hospitalization due to climate conditions.

“…It is also important to note that only general populations were used in this study. All analyses were performed according to gender and age group (< 15 years, 15-59 years, 60-74 years and ≥ 75 years), as previously described by Chan et al (2013). In addition, the number of hospital admissions was recorded from January 1, 2007 to April 30, 2013 at Nakornping Hospital, ChiangMai (NHCM).…”

“…It is well known that weather conditions and air pollution levels play an important role in hospital admissions for respiratory diseases (Chan et al, 2013;Martin et al, 2013). To investigate the influence of trace gaseous concentrations and meteorological variables on hospital admissions for respiratory diseases, Male-OPD and Female-OPD were modeled as:…”

The aims of this study were to investigate the impact of meteorological parameters and trace gas concentrations on daily hospital walk-ins and admissions in Chiang-Mai province, Thailand, during 2007Thailand, during -2013. Advanced statistical models, including t-tests, Analysis of Variance (ANOVA), Multiple Linear Regression Analysis (MLRA) and Incremental Lifetime Particulate Matter Exposure (ILPE), were constructed using meteorological data from the Pollution Control Department (PCD), Ministry of Natural Resources and Environment (MNRE), Thailand, and the Thai Meteorological Department at Chiang-Mai Province Air Quality Observatory Site (TMCS) as well as the number of walk-in and admitted patients at Nakornping Hospital, Chiang-Mai (NHCM). The results showed that all trace gaseous species and PM 10 were significantly higher during the "haze episode" than during the "non-haze period." The FTIR spectra highlight the relatively homogeneous organic functional compositions of PM 2.5 collected from urban, suburban and rural observatory sites, indicating that agricultural waste burning plays an important role in air quality during the "haze episode." The effect of age on susceptibility to respiratory diseases was investigated by separating the dataset into four groups (i.e., < 15 years, 15-59 years, 60-74 years and ≥ 75 years). The ANOVA results revealed a significant increase in hospital walk-ins and admissions for both genders in the < 15 years group (p < 0.005). MLRA revealed the significantly highest impacts of CO on hospital walk-ins for both genders. The predicted ILPE of PM 10 showed the highest values for both genders during the "haze-episode" in 2007, with average values of 3.338 ± 0.576 g and 1.838 ± 0.317 g for male and female outdoor workers, respectively, over an exposure duration of 25 years.
