Development of Dietary Knowledge and Adherence Questionnaires for Lebanese Adolescents and Their Parents.

ABSTRACT: The availability of practical tools to assess dietary knowledge and adherence is essential to evaluate the effectiveness of dietary interventions. The aims of this paper were to develop reliable dietary knowledge and adherence questionnaires, suitable for Lebanese adolescents and their parents, and to estimate the feasibility of conducting studies involving such participants in the school-based setting. Eight Lebanese high schools participated in this study (involving 220 adolescents aged 15-18 years). Self-administered dietary knowledge and adherence questionnaires (the Dietary Knowledge Questionnaire (DKQ) and the Dietary Adherence Questionnaire (DAQ), respectively) were completed by the high school students and their parents. A 24 h recall was additionally administered for the adolescents by a dietitian and a trained interviewer at school, in order to validate the adolescents' answers in the DAQ. The cognitive interview method was used to qualitatively evaluate the questionnaires. The resulting Cronbach's alpha ranged from 0.61 to 0.78 for the adolescent questionnaires and from 0.46 to 0.89 for the parental ones. In addition, 23 items (out of 25) of the adolescent DAQ matched with the administered 24 h recall. A significant negative correlation was found between the knowledge score (DKQ) and the unhealthy items of the adolescent DAQ. There was a significant positive correlation between the DKQ of the parents and the knowledge score of their children. This is the first study of dietary questionnaires involving Lebanese high school students from different regions, while also including their parents.

Project description:IntroductionHuman papillomavirus (HPV) is the most common sexually transmitted infection. HPV is responsible for cancer of cervix uteri. Despite its safety and immunogenicity, HPV vaccine hesitancy is one of the most challenging topics that pediatricians face.MethodsWe aimed to describe the impact of knowledge, attitude, and practice towards vaccines in general, on practice related to HPV vaccination in Lebanon. A questionnaire addressed to parents of students (3-18 years of age) was distributed in 2 public and 2 private schools randomly selected from the greater Beirut area during the school year 2017-2018. Questionnaires covered knowledge, attitude, and practices of vaccination in general and HPV vaccine in particular.ResultsOut of 400 distributed questionnaires, 306 (76.5%) were returned. Of the 185 parents aware of HPV vaccine, 60% hadn't given or were not planning to give the HPV vaccine to their children. Of parents not in favor of HPV vaccine, 7.5 thought that vaccines aren't necessary versus none among those in favor of HPV vaccine(p = 0.02). Thirteen percent of those not in favor of HPV vaccine thought that vaccines are not safe versus 2.7% in the group in favor (p = 0.02). An effect of gender on vaccine acceptance was noted: mothers vs fathers and daughters vs sons. Lack of recommendation by pediatricians and the thought that too little is known about the vaccine were the most selected reasons for parents not wanting to vaccinate their children against HPV, whereas cost and religious and cultural beliefs seemed to have no impact.ConclusionMost parents in our study did not vaccinate or weren't willing to vaccinate their children against HPV even when they were in favor of vaccines in general. Physician recommendation was shown to be one of the most important predictors of vaccination. Effort should be put into educating parents about the importance of the vaccine and its well-established safety and efficacy regardless of gender. Lebanese physicians should also be educated and empowered to recommend HPV vaccine more strongly and consistently.

Project description:BackgroundThe aim of our study was to develop and validate the first set of PKU-specific Health-related Quality of Life (HRQoL) questionnaires that: 1) were developed for patients with PKU and their parents, 2) cover the physical, emotional, and social impacts of PKU and its treatment on patients' lives, 3) are age specific (Child PKU-QOL, Adolescent PKU-QOL, Adult PKU-QOL), 4) enable the evaluation of the HRQoL of children by their parents (Parent PKU-QOL), and 5) have been cross-culturally adapted for use in seven countries (i.e. France, Germany, Italy, The Netherlands, Spain, Turkey and the UK).MethodsThe PKU-QOL questionnaires were developed according to reference methods including patients', parents' and healthcare professionals' interviews; testing in a pilot study (qualitative step in six countries), and linguistic validation of the finalised pilot versions in Turkish. For finalisation and psychometric validation, the pilot versions were included in a multicentre, prospective, non-interventional, observational study conducted in 34 sites in France, Germany, Italy, The Netherlands, Spain, Turkey and the UK. Iterative multi-trait analyses were conducted. Psychometric properties were assessed (concurrent and clinical validity, internal consistency reliability and test-retest reliability).ResultsData from 559 subjects (306 patients, 253 parents) were analysed. After finalisation, the PKU-QOL questionnaires included 40 items (Child PKU-QOL), 58 items (Adolescent PKU-QOL), 65 items (Adult PKU-QOL) and 54 items (Parent PKU-QOL), distributed in four modules: PKU symptoms, PKU in general, administration of Phe-free protein supplements and dietary protein restriction. The measurement properties of the Adolescent, Adult and Parent PKU-QOL questionnaires were overall fairly satisfactory, but weaker for the Child questionnaire.ConclusionsThe four PKU-QOL questionnaires developed for different ages (Child PKU-QOL, Adolescent PKU-QOL, Adult PKU-QOL), and for parents of children with PKU (Parent PKU-QOL) are valid and reliable instruments for assessing the multifaceted impact of PKU on patients of different age groups (children, adolescents and adults) and their parents, and are available for use in seven countries. They are very promising tools to explore how patients' perceptions evolve with age, to increase knowledge of the impact of PKU on patients and parents in different countries, and to help monitor the effect of therapeutic strategies.
