[Current status of oral health literacy and its influencing factors among adult orthodontic patients].

PURPOSE: To investigate the current status of oral health literacy among adult orthodontic patients and analyze its influencing factors. METHODS: Totally 163 adult orthodontic patients were recruited by convenience sampling method from November 2021 to February 2022 at the Department of Oral and Craniomaxillofacial Surgery, Center of Craniofacial Orthodontics in Shanghai Ninth People's Hospital. General information questionnaire, Chinese version of Health Literacy in Dentistry (HeLD-14), Chinese version of Self-Efficacy Scale for Self-care (SESS) and Social Support Rating Scale (SSRS) were applied. SPSS 21.0 software package was used for data analysis. RESULTS: The mean score of oral health literacy in adult orthodontic patients was (48.74±5.54), and the lowest score were obtained in concern (6.80±1.19) and support (6.40±1.59) dimensions. Multiple stepwise regression analysis showed that adult orthodontic patients' consultation self-efficacy, social support utilization, family or friends' orthodontic history and objective support were the influencing factors of oral health literacy. CONCLUSIONS: The oral health literacy in adult orthodontic patients is at a middle to high level, but concern and support literacy need to be improved. Strengthening consultation self-efficacy, objective support and utilization of social support can improve adult orthodontic patients' oral health literacy. Attention should be paid to patients who have no relatives or friends with history of orthodontic treatment.

[Analysis of information needs of patients with dentofacial deformities at different stages of treatment].

PURPOSE: To investigate the treatment experience and information needs of patients with dentofacial deformities in the process of surgical program design, surgical treatment and postoperative rehabilitation. METHODS: Thirty-six patients with dentofacial deformities at different treatment stages from March to July 2019 were selected for semi-structured interview. Colaizzi content analysis method and QSR NVivo 12.0 software were used to analyze and code the data, as well as extract the theme and genus. RESULTS: Three themes and eight categories were extracted, including① information needs in different treatment stages, mainly specific content of information needs at pre-operative preparation stage, orthognathic perioperative stage and post-operative rehabilitation stage; ② information support methods, i.e., diversified information support methods and patients' recognition of internet information;③ patients' cognition difference,namely the difference between patients' psychological expectation and the results of operation. CONCLUSIONS: Due to the treatment characteristics of orthognathic surgery and individual cognitive differences of patients, there is a large demand for information support at different stages of treatment. However, the current information support mode is limited, so it is necessary to further improve and provide scientific, professional and targeted information support for patients with dentofacial deformities.

[Qualitative study on the decision-making of orthognathic surgery in adult patients with malocclusion].

PURPOSE: The main purpose of this study was to explore the experience associated with patient's decision to have or not have orthognathic treatment. METHODS: Phenomenological methodology was used in this study. Ten patients were collected from January 2018 to March 2018, who were consulted in the Department of Oral and Craniomaxillofacial Surgery, Center of Craniofacial Orthodontics in Shanghai Ninth People's Hospital. They were interviewed by semi-structured, face to face in-depth interviews. Data were organized and analyzed by Colaizzi methods. RESULTS: By reading, analysis and extraction, two topics, i.e, motivation and interference factor were obtained. CONCLUSIONS: The treatment information service was limited. Further research is needed to improve the information services that support the treatment decision of malocclusion patients and help them to make the best choice.

[Growth follow-up of infants born macrosomia at their life of 0 to 18 months].

OBJECTIVE: To study the growth of macrosomic infants, the incidence of overweight and the factors related to overweight at 18 months old. METHODS: Eighty-four macrosomic infants without underlying diseases were enrolled in this study. Their growth was followed up regularly. Factors related to overweight at 18 months old were investigated. RESULTS: Twenty infants (24%) showed as overweight at 18 months old. More male infants were overweight than female infants (30% vs 11%; P<0.05). The overweight infants at 18 months old had a higher proportion of overweight at 6 months (80% vs 22%; P<0.01) and at 12 months old (80% vs 13%; P<0.01) than non-overweight infants at 18 months. The spearman correlation analysis demonstrated that weight-for-length Z score at 18 months old was positively correlated with birth weight and weight gain between 0 to 6 months, 7 to 12 months and 13 to 18 months (P<0.05). The strongest correlation was observed between weight gain form 0 to 6 months and weight-for-length Z score at 18 months old (r=0.597, P<0.01). CONCLUSIONS: More attention should be given to the aspect of rapid weight gain in the first 6 months of life in macrosomic infants, especially males, to prevent obesity in early childhood.
