“…The efficacy of the pedometer plus website intervention to attenuate the decline associated with the onset of cold temperatures suggests a mechanism which may contribute to the overall efficacy of our intervention. Observational studies have consistently reported declines in daily PA associated with decreasing temperatures in COPD patients[24–26]; the decline in daily step count observed in the pedometer alone group during the transition from warm to cold weather is consistent with these reports. The converse was also observed – increases in daily PA in both groups were observed during the transition from colder to warmer temperatures.…”

“…Although PA data from intermediate time points from subjects in the intervention arm are available in a subset of studies[19], continuous daily PA monitoring in control subjects is not routinely collected or reported. Lastly, there is emerging evidence linking environmental factors such as temperature and weather to daily PA[24–26]; to date the impact of temperature patterns on PA interventions has not been reported.…”

Rationale Low physical activity is highly prevalent among COPD patients and is associated with increased healthcare utilization and mortality and reduced HRQL. The addition of a website to pedometer use is effective at increasing physical activity; however, the timeline of change and impact of environmental factors on efficacy is unknown. Methods U.S. Veterans with COPD were randomized (1:1) to receive either (1) a pedometer and website which provided goal-setting, feedback, disease-specific education, and an online community forum or (2) pedometer alone for 3 months. Primary outcome was change in daily step count. Secondary outcomes included 6MWT distance, HRQL, dyspnea, depression, COPD knowledge, exercise self-efficacy, social support, motivation, and confidence to exercise. Generalized linear mixed-effects models evaluated the effect of the pedometer plus website compared to pedometer alone. Results Data from 109 subjects (98.5% male, mean age 68.6±8.3 years) were analyzed. At 13 weeks, subjects in the pedometer plus website group had significant increases daily step count from baseline relative to the pedometer alone group (804±356.5 steps per day, p=0.02). The pedometer plus website group had significant improvements in daily step count from baseline beginning in week 3 which were sustained until week 13. In subgroup analyses, the pedometer plus website attenuated declines in daily step count during the transition from summer to fall. No significant differences in secondary outcomes were noted between groups. Conclusions A website added to pedometer use improves daily step counts, sustains walking over 3 months, and attenuates declines in physical activity due to season.

Introduction:The recently developed daily and clinical visit PROactive physical activity in COPD (PPAC) instruments are hybrid tools to objectively quantify the level of physical activity and the difficulties experienced in everyday life. Our aim was to translate these instruments for the French-speaking chronic obstructive pulmonary disease (COPD) community worldwide and evaluate the influence of weather and pollution on difficulty score. Methods: The translation procedure was conducted following the guidelines for crosscultural adaptation process. The translated clinical visit (C-PPAC) was tested among COPD patients in France. A retest was conducted after an interval of at least 2 weeks. The C-PPAC difficulty score was then tested to see how sensitive it was to the influence of weather and outdoor pollution. Results: One hundred and seventeen COPD patients (age 65±9 years; FEV1: 51±20%) from 9 regions in France were included. The French version of C-PPAC was found comprehensible by the patients with an average score of 4.8/5 on a Likert-scale. It showed good internal consistency with Cronbach's α>0.90 and a good test retest reliability with an intraclass correlation coefficient of ≥0.80. The difficulty score was negatively correlated with duration of daylight (ρ=−0.266; p<0.01) and influenced by the intensity of rainfall (light vs. heavy rainfall: 68±16 vs. 76±14 respectively, p=0.045). The score was lower in patients receiving long term oxygen therapy (60 ±15 vs. 71±15, p<0.01), but not correlated with the pollution indices. Conclusion: The French versions of the questionnaires of the PPAC instruments are accepted and comprehensible to COPD patients. The difficulty score of C-PPAC is sensitive to duration of daylight and rainfall. Such weather factors must be taken into consideration when evaluating the physical activity behavior using these tools in COPD.

“…31 In the most similar study in the filed, minimum and maximum temperature, daylight duration and humidity had some impact on PA among COPD patients; nevertheless, this study included a small patient population, while duration of followup was shorter and temperature ranges smaller. 32 In conclusion, the significant effect of rainfall, but not of any other climate condition, on several measures of PA levels in our study, after controlling for elapsed time and other major determinants of disease severity among COPD patients, indicate that climate factors are probably not major determinants of PA levels in this population.…”

Longitudinal data on the effect of time and environmental conditions on physical activity (PA) among COPD patients are currently scarce, but this is an important factor in the design of trials to test interventions that might impact on it. Thus, we aimed to assess the effect of time and climate conditions (temperature, day length and rainfall) on progression of PA in a cohort of COPD patients. Patients and methods: This is a prospective, multicenter, cohort study undertaken as part of the EU/IMI PROactive project, in which we assessed 236 COPD patients simultaneously wearing two activity monitors (Dynaport MiniMod and Actigraph GT3X). A multivariable generalized linear model analysis was conducted to describe the effect of the explanatory variables on PA measures, over three time points (baseline, 6 and 12 months). Results: At 12 months (n=157; FEV 1 % predicted=57.7±21.9) there was a significant reduction in all PA measures (Actigraph step count (4284±3533 vs 3533±293)), Actigraph moderate-to vigorous-intensity PA ratio (8.8 (18.8) vs 6.1 (15.7)), Actigraph vector magnitude units (374,902.4 (265,269) vs 336,240 (214,432)), MiniMod walking time (59.1 (34.9) vs 56.9 (38.7) mins) and MiniMod PA intensity (0.183 (0) vs 0.181 (0)). Time had a significant, negative effect on most PA measures in multivariable analysis, after correcting for climate factors, study center, age, FEV 1 % predicted, 6MWD and other disease severity measures. Rainfall was the only climate factor with a negative effect on most PA parameters. Conclusion: COPD patients demonstrate a significant decrease in PA over 1 year follow-up, which is further affected by hours of rainfall, but not by other climate considerations.
