Abstract
Objective To analyze the fatigue development trajectory and its influencing factors in children with gastroenteritis using latent variable growth mixed model.Methods A total of 200 children with gastroenteritis who admitted Jingdezhen Maternal and Child Health Hospital from July 2023 to June 2025 were selected using convenience sampling.Demographic data and disease characteristics of children were collected.The multidimensional fatigue scale was used to assess the fatigue level of children at the time of the first visit,3 months after the visit,and 6 months after the visit.The optimal number of categories for the fatigue development trajectory of children with gastroenteritis was identified using latent variable growth mixed model and named accordingly.Multivariate Logistic regression was used to analyze the influencing factors between the potential categories.Results The Akaike information criterion,Bayesian information criterion and adjusted Bayesian information criterion of the 3-category model were all lower than those of the 2-category model,and both Lo-Mendell-Rubin adjusted likelihood ratio test and Bootstrap likelihood ratio test were significant.The information entropy values were all above 0.8,indicating high classification accuracy.Based on the comprehensive model adaptation indicators and practical interpretative significance,the 3-category model was determined as the optimal trajectory classification scheme.The low-fatigue group consisted of 66 cases(33％),and this group had a lower initial fatigue level and maintained stability during the follow-up period;the moderate-fatigue relief group had 70 cases(35％),initially at a moderate fatigue level,showing a slow downward trend over time;the high-fatigue decline group had 64 cases(32％),with a higher initial fatigue level,showing a significant downward trend during the follow-up.There were statistically significant differences in age,body mass index(BMI),anemia,disease duration,and perceived social support from family(PSS-Fa)scores among three groups of children(P<0.05).Multivariate Logistic regression analysis showed that age,BMI,anemia,disease duration,and PSS-Fa scores were factors influencing the course of fatigue in children with gastroenteritis.Conclusion The fatigue development trajectory of children with gastroenteritis shows heterogeneity.Age,BMI,anemia,disease duration,and PSS-Fa scores are the influencing factors of the fatigue development trajectory in children with gastroenteritis.关键词
