Abstract: Objective　To explore the cardiopulmonary functional status and related influencing factors among young people working in an office，and provide a scientific basis for improving the physiologic function and preventing diseases in the population.Methods　A total of 92 young people 20–45 years of age and engaged in office work in an electronic company in Xiamen City of Fujian Province between May and November 2016 were selected as the study subjects.Basic information and cardiopulmonary parameters were collected using questionnaires，physical examinations，and cardiopulmonary function tests.According to the maximal oxygen uptake of the study subjects after maximum exercise testing，they were divided into a high maximal oxygen uptake group（≥1.67 L/min） and low maximal oxygen uptake group（≤1.64 L/min）．Each group consisted of 45 patients.The general indicators including age，gender，body and mass index，and were compared between the two groups.Pearson correlation and partial correlation analysis were used to explore the correlation between general indicators and maximal oxygen uptake.Multivariate linear regression analysis was used to investigate the influencing factors for maximal oxygen uptake.Results　There were statistically significant differences in gender，body mass index，resting heart rate，smoking index，frequency and amount of alcohol consumption，percentage of regular exercisers，and daily amount of exercise between the two groups（P<0.05）．Age，sleep time，as well as the proportion of subjects having regular breakfast or anxiety mood were not significantly different（P>0.05） between the two groups.Pearson correlation analysis showed that body mass index，smoking index，frequency and amount of alcohol consumption，sleep time，and daily exercise amount were positively correlated with maximal oxygen uptake（P<0.05），and resting heart rate was negatively correlated with maximal oxygen uptake（P<0.05）．After adjusting for age，gender，and body mass index，partial correlation analysis showed that there was a positive correlation between the amount of daily exercise and maximal oxygen uptake（r=0.330，P=0.002），whereas resting heart rate was negatively correlated with maximal oxygen uptake（r=-0.305，P=0.005）．Multiple linear regression analysis showed that gender，body mass index，resting heart rate，and amount of daily exercise influenced the maximal oxygen uptake（P<0.05）．Conclusion　Young people working in an office have relatively low cardiopulmonary function.Gender，body mass index，resting heart rate，and amount of daily exercise influence the maximal oxygen uptake.Resting heart rate can be used to preliminarily assess cardiopulmonary function to guide the population and to improve physiology function and prevent disease.
