Abstract:

Objective To evaluate the health promotion effect of the comprehensive convalescent mode for occupational population working on plateau in a organization in Qingdao City，provide reference for the convalescent mode for occupational population working on plateau. Methods A total of 240 occupational people on plateau from June 2023 to October 2024 were selected as the study subjects and randomized into a study group（n=120） and a control group（n=120） using a random number table method. The control group received conventional convalescent mode，while the study group received a comprehensive convalescent mode on the basis of the conventional one. Both groups underwent a three-month recuperation period. The variations of biochemical indexes [oxygen saturation（SpO₂），blood lipids and myocardial enzymes]，psychological indexes[self-rating anxiety scale（SAS），self-rating depression scale（SDS） and symptom check-list 90（SCL-90）] and other physical symptoms（dizziness，nausea，insomnia，palpitation and dyspnea） were observed before and after convalescence for both groups. Results After recuperation，the SpO₂ in control group increased compared with that before recuperation[（96.58±1.93）% vs（90.42%±2.72）%]，the lactate dehydrogenase（LDH）[（196.23±18.52）U/L vs（202.77±16.84）U/L）] and α-hydroxybutyrate dehydrogenase（α-HBDH）[（120.26±13.35）U/L vs （124.06±13.27）U/L] decreased，with statistically significant differences（t=20.233，2.862，2.211，all P<0.05）. After recuperation，the SpO₂ in study group increased compared with that before recuperation（97.86%±1.41% vs 90.34%±2.66%），LDH[（181.12±21.81）U/L vs （204.31±17.21）U/L]，α-HBDH[（110.47±8.36）U/L vs （123.49±13.15）U/L]，SAS[（42.13±8.09）points vs（54.13±9.23）points]，SDS[（46.99±7.63）points vs （56.43±9.49）points] and SCL-90[（98.52±24.91）points vs （142.24±30.33）points] decreased，along with a reduction in the occurrence of other physical symptoms（18 cases vs 76 cases），with statistically significant differences（t=27.362，9.144，9.153，10.710，8.492，12.203，χ²=10.389，all P<0.05）. All these improvements were superior to those in the control group after recuperation[SpO₂：（97.86±1.41）% vs （96.58±1.93）%，LDH：（181.12±21.81）U/L vs（196.23±18.52）U/L，α-HBDH：（110.47±8.36）U/L vs（120.26±13.35）U/L，SAS：（42.13±8.09）points vs（51.58±10.07）points，SDS：（46.99±7.63）points vs （55.03±10.00）points，SCL-90：（98.52±24.91）points vs（135.72±31.21）points，other physical symptoms：（18 cases vs 53 cases）]，with statistically significant differences（t=5.866，5.785，6.808，8.014，7.002，10.205，χ²=16.585，all P<0.05）. Conclusion The comprehensive convalescent mode of a organization in Qingdao has a significant effect on the health promotion of the plateau working occupational population.
