Social psychological determinants predicating for large for gestational age infant based on health belief model
Objective To evaluate the correlationship between dietary behavior related social and psychological de-terminants in health belief model and the occurrence of large for gestational age(LGA)infants.Methods A questionnaire survey was conducted on 537 pregnant women who underwent routine prenatal examinations at the Obstetrics and Gynecology Outpatient Department of Beijing Pinggu Hospital from October 2020 to July 2021.Results Among 537 pregnant women,the delivery rate of LGA was 19.44% .Among them,women in the LGA group had a significantly higher pre-pregnancy body mass index(BMI)than those in the non-LGA group(P<0.001).Univariate analysis showed that there were no statistically signifi-cant differences of scores of social and psychological factors between LGA and non LGA pregnant women.Multivariate sta-tistical analysis showed that perceived risk of gestational diabetes related increase of medical costs[OR=1.77,95% CI(1.12-2.81)]and pain of fingertip blood collection[OR=0.59,95% CI(0.40-0.87)]predicted LGA.Perceived benefits of balanced diets helped to maintain an appropriate weight gain[OR=0.39,95% CI(0.17-0.89)].Scores of four items in the action cue to receive healthy diet information from the media[OR=0.69,95% CI(0.52-0.91)]were significantly associated with the incidence of LGA,and these associations remained significant after adjusting for age,preconception BMI,and parity.Conclusion Pregnant women who are obese before pregnancy have a higher change to deliver a LGA baby.Pregnant women's agreement with the perceived risks,perceived benefits,and cues for action associated with a balanced diet was sig-nificantly associated with the risk of LGA deliveries.Nutrition and health education curriculum designed according to health belief model improves the pertinence and effectiveness of health education to prevent the occurrence of LGA.
