Effectiveness Of Nursing Intervention Based On The Integrated Theory Of Health Behavior Change On Improving The Physical Activity Level Of Pregnant Women

Objective:To explore the effects of nursing intervention based on the integrated theory of health behavior change(ITHBC)on improving physical activity of pregnant women and and delivery outcomes.The aim is to improve the awareness of pregnant women and medical staff on physical activity during pregnancy and further improve perinatal health measures.Promote Promoting physical and mental health of mothers and infants.Methods:Seventy-five pregnant women in the obstetrics clinic were selected by convenience sampling and were further randomly divided into the control group(37cases)and the experimental group(38 cases)using SPSS from January 2022 to September 2022.The control group received routine prenatal examination and health education,while the experimental group received nursing intervention based on ITHBC theory.The intervention lasted from 13 to 15 weeks of gestation until labor.The general information questionnaire,Pregnancy Physical Activity Questionnaire(PPAQ),Pregnancy Exercise Self-Efficacy Scale(P-ESES),Oswestry disability index(ODI)and Pregnancy Anxiety Scale(PAS)were used before the intervention.PPAQ、P-ESES、ODI disability index and PAS were collcted before labor,outcome data of pregnant women were collected within 1 week after delivery.Delivery outcomes include appropriate weight gain during pregnancy,delivery mode,and incidence of macrosomia.Excel was used for data collation and input,and SPSS25.0 statistical software was used for data analysis.Results:1.Comparison of physical activity energy consumption: Before intervention,there was no significant difference in the compliance rate of exercise and total energy consumption per week between the two groups.After the intervention,the exercise compliance rate of the experimental group was higher than that of the control group,and the difference was statistically significant(P<0.05);The intensity and type of physical activity increased in both groups,but the total energy expenditure,moderate intensity physical activity and exercise expenditure per week in the experimental group were significantly higher than those in the control group(P<0.05).2.Comparison of P-ESES scores: Before the intervention,there was no significant difference between the two groups(P>0.05).After the intervention,the total score of the experimental group(32.66±4.97)was significantly higher than that of the control group(27.05±5.93)(P<0.05);The total score of P-ESES in the two groups was higher than that before the intervention,but the total score of the experimental group was significantly higher than that before the intervention(P<0.001).The P-ESES in the experimental group showed greater improvement in overcoming motor disorders,overcoming emotional disorders,and overcoming support disorders(P<0.05).3.Comparison of PAS scores: Before intervention,there was no significant difference in the total score and dimension scores of PAS between the two groups(P<0.05).After the intervention,the score of the experimental group(49.34±6.81)was significantly lower than that of the control group(54.00±8.61),and the difference was statistically significant(P<0.05).The general anxiety(10.89±2.45)and childbirth anxiety(14.66±2.93)in the experimental group were significantly lower than those in the control group(12.22±2.87;16.59±3.82),and the differences were statistically significant(P<0.05).4.Comparison of the incidence of pregnancy-related low back pain and ODI disability index: Before the intervention,there was no significant difference in the incidence of pregnancy-related low back pain and ODI disability index between the two groups(P<0.05).After the intervention,the incidence of pregnancy-related low back pain in the experimental group(47.37%)was lower than that in the control group(70.27%),and the ODI disability index in the experimental group was also lower than that in the control group,and the differences were statistically significant(P<0.05).5.Comparison of pregnancy and delivery outcomes: After the intervention,the appropriate rate of gestational weight gain in the experimental group was 89.47%,which was significantly higher than that in the control group(62.16%),and the incidence of cesarean section and macrosomia in the experimental group was significantly lower than that in the control group.The difference was statistically significant(P<0.05).Conclusion:1.Nursing intervention based on the integrated theory of health behavior change can help to improve the level of physical activity during pregnancy,increase the enthusiasm of physical activity,and maintain a regular and reasonable way of activity.2.Nursing intervention based on the integrated theory of health behavior change can improve the level of exercise self-efficacy of pregnant women,relieve anxiety of pregnant women,reduce pregnancy-related low back pain,and improve the outcome of pregnancy and delivery.
