Summary
Objectives: To identify levels of physical activity (PA) among the Spanish population with asthma and chronic obstructive pulmonary disease overlap (ACO). A further aim was to analyze differences in PA levels by sex, age, education, marital status, cohabiting, smoking habits, alcohol consumption and body mass index (BMI).
Methods: In this cross sectional study, data from the Spanish National Health Survey 2017 were analyzed. A total of 198 people with ACO aged 15–69 years were included in the analyses. The short version of the international physical activity questionnaire (IPAQ) was used to measure total PA (MET·min/week). PA was further classified as low, moderate and high, and analyzed according to sample characteristics. Data were analyzed using the Mann-Whitney U test, Kruskal-Wallis H test and chi squared test. Statistical significance was
set at p<0.05.
Results: People with ACO engaged in a mean volume of 2038.1 MET·min/week. Those aged 30–60 years and those with normal weight were significantly more active than those aged ≥60 and those with obesity. When classifying PA level in low, moderate and high, results showed no significant differences between sample characteristics. Overall, moderate and high levels of PA were the most and least frequent levels (48.0% and 16.2%, respectively).
Conclusions: More than three out of ten Spanish adults with ACO do not achieve PA recommendations. Therefore, it is recommended to implement programs that promote the importance and benefits of PA among the Spanish population with ACO, and such programs should focus on older adults and those who are obese.

Relevance
Spanish people with ACO have a moderate PA level but, it is important to note that more than three out of ten Spanish people with ACO do not achieve PA recommendations. Therefore, it is recommended to implement programs that promote the importance and benefits of PA among those with ACO residing in Spain. These programs should focus on older adults and those who are obese.
