Chest
Clinical InvestigationsThe Influence of Spring and Summer New England Meteorologic Conditions on the Respiratory Status of Patients With Chronic Lung Disease
Section snippets
Patients
Fourteen patients from the greater Hartford area who had completed an outpatient pulmonary rehabilitation program and were attending weekly exercise maintenance sessions were studied. These patients were selected because they had significant exertional dyspnea despite optimum medical therapy and were considered reliable informants. They were asked to record clinical information daily in a diary from the first day of spring through the last day of summer 1991. This information was returned to
Patients
Demographic information, pulmonary function tests, and measurements of respiratory status over the study period are given in Table 1. Eleven patients had chronic obstructive pulmonary disease, two (patients 10 and 13) had steroid-dependent asthmatic bronchitis, and one (patient 1) had sarcoidosis with pulmonary fibrosis and airways obstruction. All were ex-cigarette smokers; three were receiving continuous, low-flow oxygen therapy. Although a 15 percent or greater improvement in FEV1 following
DISCUSSION
The objective of this investigation was to determine which meteorologic conditions, if any, were associated with changes in the respiratory status of a group of patients with chronic lung disease. Although this group was mixed with respect to diagnoses, they were all ex-smokers with moderate to severe airways obstruction and had persistent dyspnea despite optimal medical therapy. The LRI and mood were also recorded, anticipating their potential confounding influence on respiratory status.

Higher temperature and humidity exacerbate pollutant-associated lung dysfunction in the elderly
2024, Environmental ResearchThe impact of ambient air pollution on lung function and respiratory symptoms in elite athletes
2023, Science of the Total EnvironmentCitation Excerpt :Previous studies have shown contradictory results on the effect of temperature on lung function. Temperature and lung function showed positive associations with each other when the temperature was relatively low (Collaco et al., 2011; Donaldson et al., 1999; Li et al., 2014; Mann et al., 1993; Zhang et al., 2015). Our study found a positive relationship between temperature and lung function, probably because the average temperature during the study period was 9.81 °C (minimum: −8.1 °C, maximum: 26.9 °C), and our study period did not include very high temperatures.
Life-time summer heat exposure and lung function in young adults: A retrospective cohort study in Shandong China
2022, Environment InternationalCitation Excerpt :A study conducted in New England supports our findings. This study found that increased temperatures were significantly associated with the decrease of lung function and increased frequencies of respiratory tract infection only in summer (Mann et al., 1993). In addition, there are also differences in our tracking periods for temperature exposure.
Lung function association with outdoor temperature and relative humidity and its interaction with air pollution in the elderly
2018, Environmental ResearchCitation Excerpt :A previous study of 21 healthy university students (> 6000 measurements), found a significant inverse association between temperature and morning peak expiratory flow, but no significant association with FEV1 (Wu et al., 2014). Other studies focusing on populations with preexisting diseases have reported associations between increases in ambient temperature and reduced lung function in subjects with chronic lung diseases (Mann et al., 1993), in cystic fibrosis patients (Collaco et al., 2011) and in children with asthma (Li et al., 2014). The current study showed that associations of temperature and relative humidity with lung function last several days.

2016, Science of the Total EnvironmentCitation Excerpt :It included the large number of children (N = 71,768) from 30 cities of China. The meteorological environment of participant cities included tropic, temperate and frigid climate and the range of annual ambient temperature were from 4.5 to 24.6 °C, which is wider than previous studies (Li et al., 2014; Mann et al., 1993; Wu et al., 2014). Second, we used GAM and smooth function to study the relationship between ambient temperature and FVC, and adjusted the socioeconomic status, physical activity level and air pollutants in the model, being reasonable to identity the association between ambient temperature and lung function.
