Investigation on current status and analysis of influencing factors of phalanx bone mineral density in middle-aged and elderly people in Chengdu

Objective To understand the current status of bone mineral density level in middle-aged and elderly people in Chengdu,and to analyze its influencing factors.Methods A random sample of 1954 healthy people from the physical examination center of Sichuan People′s Hospital was selected.A questionnaire survey was used to collect demographic data,chronic medical history,diet,exercise,and other conditions.The phalanx bone mineral density was collected by on-site measurement.Results With the increase of age,bone mineral density decreased significantly,and the bone mineral density of females in the same age group was lower than that of males(P<0.05).The bone mass loss exceeded 12%when the males were>65 years old and females were>55 years old.Univariate analysis showed that age,gender,hypertension,diabetes,alcohol consumption,smoking,exercise,sun exposure and drinking milk,coffee,tea and carbonated beverages were associated with the level of bone mineral density.Multiple linear regression analysis showed that diabetes,smoking and regular drinking of coffee or tea were risk factors for the decrease of bone mineral density(P<0.05).Regular exercise,drinking milk and sun exposure were protective factors for bone mineral density(P<0.05).Conclusion Bone mineral density level is affected by various factors.Regular exercise,drinking milk and sun exposure can relieve the decrease of bone mineral density.Maintaining blood glucose stability,quitting smoking and drinking less coffee and tea can help to prevent osteoporosis.It is necessary to strengthen health education for high-risk population.
