Objective To investigate the chronic comorbidities among elderly healthcare objects

so as to provide evidence for clinical decision-making.Methods Based on the method of random sampling

123 cadres aged over 65 years who underwent health check-up in a Beijing hospital during the period from October 2015 to July 2016 were included in this survey.Results The average number of comorbidities was 3.52±1.48 in the overall population;2.80±1.05

3.45±1.58 and 4.29±1.45 in the young old（65

&

lt;75 years old）

middle old（75

&

lt;85 years old）and very old（≥85 years old）groups

respectively.The differences in the average number of comorbidities were statistically significant among different age groups（P

<

0.05）.Pairwise comparisons showed that

the average number of comorbidities in the very old group was much higher than those in the young old or middle old groups（P

<

0.05）.Five cadres（all males）had only one kind of comorbidity

32（all males）had two kinds of comorbidities

and the other 86（80 males

6 females）had at least three kinds of comorbidities;the differences were statistically significant among different age groups（P

<

0.05）.The most common comorbidities were cataract（91

73.98%）

prostatic hyperplasia（88

71.54%）

hypertension（77

62.60%）

hyperlipedemia（56

45.53%）and diabetes（36

29.27%）.Conclusion The number and complexity of comorbidities tend to increase with advancing age.Thus

it is important for healthcare providers to pay close attention to age-related changes in elderly healthcare objects

be fully aware of their comorbidities

and learn new ideas about comorbidity management

so as to maintain and improve their quality of life.
