To investigate the correlation between the incidences of anemia and hypoproteinemia and age and sex in the patients with chronic obstructive pulmonary disease (COPD).

With a convenient sampling method, 76 COPD patients who were treated in our hospital from January 2013 to October 2017 were selected as the observation group and the other 76 healthy persons who received the physical examination in our hospital at the corresponding time period were selected as the control group. The clinical data, such as the gender and age, and the incidences of anemia and hypoproteinemia were recorded for the two groups, and correlation analysis was conducted.

The incidences of anemia and hypoproteinemia were respectively 51.3% and 40.8% in the observation group, and respectively 5.3% and 3.9% in the control group, which were significantly higher in the observation group than the control group (P<0.05). In the observation group, 30 patients suffered from mild anemia, 6 from moderate anemia, 3 from severe anemia, 25 from mild protein deficiency, 3 from moderate protein deficiency, and 3 from severe protein deficiency. The incidence of anemia in the male patients was significantly higher than that of the female ones (P<0.05). There was no significant difference in the incidences of hypoproteinemia between different sexes (P>0.05). The incidences of anemia and hypoproteinemia in the different age groups were significantly different (P<0.05). Logistic regression analysis showed that sex and age were risk factors for anemia in the COPD patients, and age was the risk factor for hypoproteinemia (P<0.05).

The incidences of anemia and hypoproteinemia in the COPD patients are relatively high. And sex and age are risk factors for anemia and age is a risk factor for hypoproteinemia. Therefore, preventive management should be carried out actively.
