To analyze the relevant factors affecting the frequency and behavior of health check-up among the population of medical examinees.

From January to June 2022, 491 health examinees who had health check-ups at the Second Affiliated Hospital of Shandong First Medical University were included.Basic information of the check-up population and their needs for check-up services (form of check-up, content of check-up, cost of check-up, form of feedback on check-up results, and needs for check-up providers) were obtained based on a questionnaire survey.According to the frequency of previous medical check-up, the examinees were divided into never-check-up group (frequency of check-up was 0, n=45), the irregular check-up group (the interval between two physical examinations >1 year, n=49) and the regular check-up group (frequency of check-up=1 year, n=347). The frequency of previous medical check-up was used as the dependent variable, and the age, gender, education level, income, form of medical check-up and cost of medical check-up were used as independent variables to analyse the relevant factors affecting the frequency of their medical check-ups.The above count data were analyzed by one-way analysis using chi-square test, and the count data with statistically significant differences in one-way analysis were analyzed by binary logistic regression.The statistical software was SPSS 21.0.

The study included 491 medical examinees, of which 9.16%(45/491) were in the never-check-up group, 20.16%(99/491) in the irregular check-up group and 70.68%(347/491) in the regular check-up group. The impact of demography characteristics of physical examinees on the frequency of health check-up, and there were statistically significant differences in the frequency of health check-up in terms of gender, job, education, and income (χ²=21.826, 157.113, 104.764, 45.486, all P<0.05). The understanding of health check-up and the attention paid to one's own health were influencing factors that affected the frequency of health check-up. There were statistically significant differences in the frequency of health check-up in necessity of health check-up, attention to one's own health, health check-up forms, health check-up institutions, health check-up price and health check-up contents (χ²=9.277, 25.863188.239, 59.115, 39.250, 28.314, all P<0.05). Logistic regression analysis showed gender, job type, monthly income, necessity of health check-up, concerns for items of check-up, forms and institutions of check-up were influencing factor of health check-up frequency(all P<0.05).

The health check-up behavior of the population and the frequency of regular medical check-ups are influenced by the factors such as gender, education, occupation, income, form of medical check-up, price of medical check-up, choice of medical check-up institution and the degree of concern for one’s own health. The popularisation of health check-ups for special groups such as men, low-income people, low literacy and insufficient awareness of the importance of one’s own health will help improve the overall health awareness of the population.
