The gout epidemic in French Polynesia: a modelling study of data from the Ma'i u'u epidemiological survey.

BACKGROUND: Gout is the most common cause of inflammatory arthritis worldwide, particularly in Pacific regions. We aimed to establish the prevalence of gout and hyperuricaemia in French Polynesia, their associations with dietary habits, their comorbidities, the prevalence of the HLA-B*58:01 allele, and current management of the disease. METHODS: The Ma'i u'u survey was epidemiological, prospective, cross-sectional, and gout-focused and included a random sample of adults from the general adult population of French Polynesia. It was conducted and data were collected between April 13 and Aug 16, 2021. Participants were randomly selected to represent the general adult population of French Polynesia on the basis of housing data collected during the 2017 territorial census. Each selected household was visited by a research nurse from the Ma'i u'u survey who collected data via guided, 1-h interviews with participants. In each household, the participant was the individual older than 18 years with the closest upcoming birthday. To estimate the frequency of HLA-B*58:01, we estimated HLA-B haplotypes on individuals who had whole-genome sequencing to approximately 5× average coverage (mid-pass sequencing). A subset of individuals who self-reported Polynesian ancestry and not European, Chinese, or other ancestry were used to estimate Polynesian-ancestry specific allele frequencies. Bivariate associations were reported for weighted participants; effect sizes were estimated through the odds ratio (OR) of the association calculated on the basis of a logistic model fitted with weighted observations. FINDINGS: Among the random sample of 2000 households, 896 participants were included, 140 individuals declined, and 964 households could not be contacted. 22 participants could not be weighted due to missing data, so the final weighted analysis included 874 participants (449 [51·4%] were female and 425 [48·6%] were male) representing the 196 630 adults living in French Polynesia. The estimated prevalence of gout was 14·5% (95% CI 9·9-19·2), representing 28 561 French Polynesian adults, that is 25·5% (18·2-32·8) of male individuals and 3·5% (1·0-6·0) of female individuals. The prevalence of hyperuricaemia was estimated at 71·6% (66·7-76·6), representing 128 687 French Polynesian adults. In multivariable analysis, age (OR 1·5, 95% CI 1·2-1·8 per year), male sex (10·3, 1·8-60·7), serum urate (1·6, 1·3-2·0 per 1 mg/dL), uraturia (0·8, 0·8-0·8 per 100 mg/L), type 2 diabetes (2·1, 1·4-3·1), BMI more than 30 kg/m2 (1·1, 1·0-1·2 per unit), and percentage of visceral fat (1·7, 1·1-2·7 per 1% increase) were associated with gout. There were seven heterozygous HLA-B*58:01 carriers in the full cohort of 833 individuals (seven [0·4%] of 1666 total alleles) and two heterozygous carriers in a subset of 696 individuals of Polynesian ancestry (two [0·1%]). INTERPRETATION: French Polynesia has an estimated high prevalence of gout and hyperuricaemia, with gout affecting almost 15% of adults. Territorial measures that focus on increasing access to effective urate-lowering therapies are warranted to control this major public health problem.

Impact of e-cigarette experimentation and use on smoking behavior among adolescents aged 15-16 years in the Loire department, France.

INTRODUCTION: We describe the vaping and smoking habits of French adolescents aged 15-16 years in the Loire department with a view to assess the impact of e-cigarette experimentation and use on their smoking behavior. METHODS: This quantitative, cross-sectional, single-center and observational study conducted from January to July 2019 targeted 6622 students aged 15-16 years attending public high school in the Loire department, France. RESULTS: A total of 4937 (74.6%) adolescents were included. Of these, 73.2% were non-vapers and 72.2% non-smokers; 66.0% of adolescents were non-vapers and non-smokers. Slightly less than half of adolescents had experimented with e-cigarettes (44.6%), more than half of whom (26.8%) continued to use vaping products, with 6.02% vaping daily. Likewise, a little less than half of adolescents had experimented with smoked tobacco (42.4%), more than half of whom (27.8%) continued to use smoking products, with 10.3% smoking daily. Vapers and smokers (20.6%) tended to begin with the use of smoked tobacco and to progress to the dual use of vaping and smoked tobacco products. Vaping had a positive effect, as 71.8% of vapers who smoked tobacco before initiating vaping stopped or reduced smoking following their progression to this double use. More than half of tobacco users are daily users while this daily use affects only 1/3 boys and 1/6 girls for vape. Finally, nearly 80.7% of adolescents who had never smoked before vaping did not smoke at the time of the study. CONCLUSIONS: Our data suggest that vaping has a rather marginal impact on smoking initiation among French adolescents aged 15-16 years in the Loire department. They therefore neither confirm nor completely disprove the gateway effect theory, relating to use of tobacco subsequent to vaping.

Regional French evolution of tobacco and e-cigarette experimentation and use among adolescents aged 15-16 years: A cross-sectional observational study conducted in the Loire department from 2018 to 2020.

Background: We assessed/compared the evolution of tobacco and e-cigarette experimentation and use among French adolescents of the Loire department aged 15-16 years. Methods: A descriptive, cross-sectional/observational study conducted in 2018-2020 among 7,950 Year 11 pupils attending 27 public secondary schools of the Loire department, France. Results: From 2018 to 2020, 66.18% of adolescents were "non-vapers and non-smokers", 19.76% were "vapers and smokers", 7.90% were "non-vapers and smokers" and 6.15% were "vapers and non-smokers". E-cigarette experimentation was more prevalent than tobacco experimentation (44.92% vs 41.67%), and daily vaping was less prevalent than daily smoking (5.40% vs 10.24%). More boys than girls were daily vapers or daily smokers. A decrease was observed in tobacco experimentation (from 41.22% in 2018 to 39.73% in 2020) and e-cigarette experimentation (from 50.28% in 2018 to 41.25% in 2020). Current vaping remained stable, with an increase in daily vaping. French adolescent vapers frequently use e-liquids with little or no nicotine or with fruit or sweet flavours. Conclusions: Adolescents used e-cigarettes mainly for experimental and/or recreational purposes, with no intention of progression to daily smoking. Although the design of this study is not longitudinal and caution must be exercised, from our cross-sectional observational study data, it appears that the proportion of "non-vapers and non-smokers" tended to increase. "Smokers" tended to progress to the dual use of vaping and smoked tobacco, with the likely intention to reduce or quit smoking.

Defining Life Skills in health promotion at school: a scoping review.

Background: Life Skills have been central to Health Promotion interventions and programmes with children and adolescents for over 40 years. School is a strategic setting for Life Skills education. Recently, policy-and decision-makers have focused on Life Skills development for youth. Research on Life Skills has gained momentum. Different terms are used to discuss and define Life Skills. Research identifies a lack of conceptual definition. The purpose of this study is to identify the definitions in the literature in English and French, and to reach a conceptual and consensual definition. Method: The Scoping Review methodology was used. Three research questions aim to identify how Life Skills are defined in the field of health promotion at school, to see whether a conceptual and consensual definition exists, and, if relevant, to propose a conceptual definition. The search was conducted in 5 databases by 3 reviewers. This study focused on full-text publications in English or French, human studies, health promotion in school, school pupils, teacher training, and with a definition of Life Skills. Publications on after-school activities, higher education outside teacher training, adult education, other than peer-reviewed scientific papers were excluded. Results: 48 publications were included in English and 7 in French. NVIVO was used to determine and compare the French and English terms used for Life Skills and their definitions. According to the three research questions, (i) the terms used to define Life Skills are diverse and numerous, with different purposes at school in relation to health promotion, and different taxonomies, and relate to different areas of research; (ii) no consensual, conceptual definition of Life Skills was found; (iii) further semantic, epistemological and ontological clarifications are required. Conclusion: Some conceptual definitions of Life Skills exist without consensus. Life Skills being at the crossroads between different fields could explain this and is illustrated by the multiplicity and diversity of the terms employed, and the various taxonomies and purposes used at school in health promotion. This may also explain why they are difficult to evaluate. Defining Life Skills consensually cannot be achieved due to the diversity of research perspectives from different fields.

Évolution des comportements tabagique et de vapotage d'adolescents français de 15 à 18 ans (2018-2020).

Introduction : Longitudinal studies make it possible to study the evolution of a class of individuals over time. However, they are rarely used in France to observe the same population of young adolescents according to their grade level over the course of several years.Purpose of research : Based on the longitudinal monitoring of repeated annual cross-sectional studies on young adolescents (from 15 to 18 years old) conducted at the Honoré d’Urfé public high school (Saint-Étienne, Loire, France) involving 336 10th grade pupils in 2018, 360 11th grade pupils in 2019 and 273 12th grade pupils in 2020, we observed and studied students’ smoking and vaping behavior over a period of three years.Results : Between the ages of 15 and 18 years, the prevalence of tobacco experimentation increased almost linearly (39.10%, 47.50%, and 53.11%), while the prevalence of ‘non-smoking’ decreased by 4.5%. In addition, the prevalence of e-cigarette experimentation was stable (46.38%, 49.44%, 47.62%), whereas the prevalence of daily vaping increased by 5.0%.Conclusions : The prevalence of tobacco experimentation tends to increase with age and to catch up with that of e-cigarette experimentation, which remains stable at this stage of adolescence. Introductions to these two products seem to be rather recreational, playful, and experimental in nature, and do not have a significant connection with the development of their daily use or propensity to addiction.

Validation française de l'échelle de littératie en santé des élèves HLSAC (Health literacy for school-aged children).

INTRODUCTION: Health literacy, defined by WHO (World Health Organization) as the motivation and ability of individuals to access, understand and use information in ways that promote and maintain good health, is a critical health issue. Indeed, low levels among individuals can be associated with problems in interpreting health information, more frequent hospitalizations, incorrect use of medicines, poorer overall health, and increased mortality. PURPOSE OF RESEARCH: While the definitions and the major role of health literacy on the health of individuals are clearly established and seem to be in agreement, the same cannot be said for its measurement. There are only about fifteen tools for college students and none of them are in French. The purpose of this research is therefore to develop a measurement tool that can be used to assess the health literacy level of French schoolchildren. METHODOLOGY AND RESULTS: After a translation and retro-translation of the existing HLSAC scale (subjective health literacy brief instrument for school-aged children), we submitted it to 385 secondary school students aged 11 to 16 years old from the departments of Ain and Loire (average age = 12.8 years). We then carried out an exploratory factorial analysis, calculated the internal consistency of our tool, and then carried out a confirmatory factorial analysis, calculated fit indices. Finally, we checked the concurrent validity by calculating correlations with a related concept (self-efficacy). CONCLUSIONS: Our scale seems to have sufficient psychometric qualities to be able to apprehend the level of health literacy among middle-school students.

Characterizing the Content Related to Oral Health Education on TikTok.

Neglecting oral hygiene in adolescents negatively affects dental caries and periodontal diseases, in addition to social and emotional well-being. Thus, the TikTok platform (ByteDance, Beijing, China)as a social media could be a powerful channel to provide health-related information and educational content. This study aims to assess the quality of the TikTok videos corresponding to #oralhealtheducation. Sixty-nine videos were identified. Three oral health professionals (OHP), three health education professionals (HEP), and ten of TikTok's target audience watched and evaluated the videos from a qualitative questionnaire. OHP detected false or incorrect information in 11.6% (8/69) of the videos. At least two HEPs reported being unable to detect this type of content or whether the video met dental ethics standards in both the videos. Disagreement was observed among the professionals themselves. The evaluation indicated that TikTok's target audience was satisfied with the products viewed with an average score of >2.5, unlike the professionals, whose average score was <2.5 on a scale of 0 to 5. Users are advised to think critically and to consider the content of TikTok oral health videos with caution. The involvement of health professionals in the writing and validation of the videos could be an added value to positively respond to the needs of the adolescents.
