Integrating perspectives of transgender and gender-diverse youth, family members, and professionals to support their health and wellbeing - a mixed-method study protocol.

BACKGROUND: The current literature highlights a strong link between the poor health outcomes of transgender and gender diverse (TGD) individuals and their negative experiences in various areas of life. Most of these publications rely on adults' memories, lacking a focus on the current experiences and needs of young transgender and gender-diverse individuals. Furthermore, previous studies on support for these young people often solely consider the perspectives of TGD adults or professionals and rarely involve parents' viewpoints. METHODS: This study will use a mixed sequential method with a participatory approach. Firstly, the qualitative phase will explore the difficulties and needs of TGD (15-20 years old) and of the families and professionals who support them. Results from this part will be used to develop the questionnaire for the quantitative phase, with the help of a community board. Secondly, based on participatory epidemiological research, the quantitative phase will use an intersectional perspective to measure the impact of individual and structural factors on the quality of life and well-being of transgender and gender-diverse young people. Finally, a co-creation phase will be undertaken to formulate recommendations based on the results of the first two phases. DISCUSSION: This research aims at better understanding the influence of gender identity on the quality of life and health of TGD young people and their families and to identify protective and risk factors that affect their vulnerabilities. ETHICS AND DISSEMINATION: This study has been approved by the Ethics Committee of the Erasme Faculty Hospital (CCB B4062023000140). As this research is participatory and part of a PhD dissertation, we aim to disseminate the results through our partners' networks and structures locally, and internationally through conferences and peer-reviewed journals.

Job stress, a source of hypertension among workers in Sub-Saharan Africa: a scoping review.

BACKGROUND: Hypertension remains one of the leading risk factors for cardiovascular disease. Contrasting with the high-income countries where the rates of hypertension decline, it increases in Sub-Saharan African countries. The age group most affected by hypertension is the working population. Several studies carried out in Europe, North America, and Asia, underline the influence of job stress on the occurrence of hypertension. The objective of this review was to explore current knowledge about hypertension and job stress in Sub-Saharan Africa. METHODS: We conducted a scoping review using Arksey and O'Malley's framework to synthesize findings. We searched in PubMed, Scopus, and ProQuest databases. The inclusion criteria were peer-reviewed manuscripts published on March 1, 2023, conducted among workers in Sub-Saharan Africa, reported hypertension and job stress, and using quantitative methodologies. Data were assessed independently by two researchers. RESULTS: In total, 295 articles were identified from databases. Of these, only 12 articles met the inclusion criteria and were included in the review (9 cross-sectional studies and 3 case-control studies). These studies focused on sectors reported as stressful (health, banking, education, and industries). The prevalence of hypertension varied from 14.3% to 45.9%, with a high proportion of hypertensive participants (35.4%-70.6%) who were unaware that they had hypertension. Job stress was significantly associated with hypertension (OR = 2.4 [1.5-4.4]) and stress management was inversely associated with hypertension (r = -0.14, p < 0.05). However, no study reported an existing workplace health promotion program implemented, especially regarding cardiovascular disease risk factors. CONCLUSION: Data available in the literature show that stressful working conditions may be associated with hypertension. We are faced with an increasing prevalence of hypertension among workers in Sub-Saharan Africa, where a large proportion of them are unaware that they have hypertension. Thus, there is a need to implement workplace prevention and health promotion strategies in Sub-Saharan Africa.

Adaptation, implementation, and evaluation of an online health sciences training program for brief smoking intervention: A pre-post study in four European countries.

BACKGROUND: Tobacco cessation intervention has a positive impact on quality of care. For health professionals, limited competency in this area may be associated with poor training during their academic programs. There is a clear need to further develop and implement training programs to improve tobacco cessation knowledge, skills, and attitudes among healthcare students. OBJECTIVES: The aim of this study was to assess the effectiveness of the innovative online training program "Brief Intervention in Smoking Cessation" for healthcare students to improve their knowledge, skills, and attitudes. DESIGN: A pre-post evaluation study with a satisfaction assessment tool was used. SETTING: Seven universities from four European countries, including Belgium, Portugal, Spain, and the United Kingdom, participated. PARTICIPANTS: One thousand and seventy-two (1072) undergraduate students participated, with 851 completing the online program. METHODS: All participants completed the "Brief Intervention in Smoking Cessation" online program, which consisted of five theoretical modules, five videos, and three virtual simulation cases between January 2020 and June 2022. Knowledge was assessed by a multiple-choice test, and practical skills were assessed by a simulation algorithm, both of which were developed by education and smoking cessation experts. Competency was achieved when students successfully completed both assessments. Satisfaction was measured using an ad hoc 16-item questionnaire. Pre-post changes in knowledge were assessed using a paired Student's t-test. RESULTS: Eighty-six percent of the students achieved smoking cessation competency. Students significantly improved their knowledge score on a scale of 0 to 10 points, with a mean pre-program score of 3.79 vs a mean post-program score of 7.33 ([-3.7 - -3.4] p < 0.001), acquiring sufficient attitudes and skills (simulation mean of 7.4 out of 10 points). Students were highly satisfied with the program (8.2 out of 10) and recommended it to other students (8.4 out of 10). CONCLUSIONS: The "Brief Intervention in Smoking Cessation" online training program is effective for the acquisition of smoking cessation competencies among European health profession students.

Eight-year experience of maternal death surveillance in Morocco: qualitative study of stakeholders' views at a subnational level.

BACKGROUND: Since 2009, Morocco has been implementing the Maternal Death Surveillance System (MDSS). The results obtained indicate significant regional variations in terms of implementation stage, completeness of maternal death reporting, and information use for action. The objective of this research is to better understand the contextual factors involved in the implementation process and use of MDSS, with a focus on the facilitators and barriers, as experienced by stakeholders in health regions.  METHODS: Evaluation research was conducted in 2017 based on a descriptive qualitative study using semi-structured in-depth interviews, in four out of the twelve health regions of Morocco. A total of thirty-one in-depth interviews were held with members of regional committees of maternal death reviews (RC-MDR) and other key informant staff. Interviews focused on participants' views and their experiences with the MDSS since the introduction in 2009. We conducted thematic analysis relied on inductive and deductive approaches. Applying the Consolidated Framework for Implementation Research guided data analysis and reporting findings.  FINDINGS: Engaging leadership at all health system levels, regular training of district and regional MDSS coordinators and supportive supervision at a national level were the most important MDSS implementation facilitators. Reported barriers were essentially related to the review system: Irregular review meetings, blame culture, high turn-over of RC-MDR members, lack of analytical capacity to inform the review process and formulate recommendations, finally limited accountability for recommendation follow-up. While financial incentives boosted MDSS adoption, they were nonetheless a substantial barrier to its sustainability. CONCLUSIONS: The MDSS is a complex process that requires taking numerous steps, including the commitment of multiple stakeholders with varying roles as well as information sharing across health system levels. Contextual factors that influence MDSS implementation at the sub-national level are to be considered. Horizontal and vertical communication about MDSS goals and feedback is crucial to strengthen stakeholders' commitment, hence improving quality and use of MDSS. Furthermore, health regions should place emphasis on making high-quality recommendations in partnerships between the regional management teams, RC-MDR members and external stakeholders.

Identification of Modifiable Risk Factors of Exacerbations Chronic Respiratory Diseases with Airways Obstruction, in Vietnam.

OBJECTIVES: to determine modifiable risk factors of exacerbations in chronic respiratory diseases with airways obstruction (i.e., asthma and COPD) in southern Vietnam. METHODS: an environmental and health-related behavioural questionnaire was submitted to patients with both chronic respiratory symptoms and airways obstruction. An exacerbation was defined as any acute worsening in clinical symptoms requiring a change in treatment, in a patient receiving prophylactic therapy. RESULTS: 235 patients were evaluated, including 131 (56%) chronic obstructive pulmonary disease (COPD) and 104 (44%) asthmatics. There were 75% males and 69% smokers. Occupational exposure accounted for 66%, mainly among construction and industry workers. Smoking was associated with more severe airways obstruction. Respiratory exacerbations were reported in 56/235 patients (24%). The risk of exacerbation was increased in patients with a lower education level, exposure to occupational pollutants, cumulative smoking ≥ 20 pack year, housing space < 10 m2, and poorly ventilated housing. Based on multivariate analysis, the risk of exacerbation remained significantly higher among patients with occupational exposure and low housing space per person. CONCLUSIONS: besides smoking cessation, more supportive policies, including improvement of occupational environment and housing design for better ventilation, are needed to prevent the severity of chronic respiratory diseases in Vietnam.

Redefining Fatherhood in a Migratory Context: A Narrative Inquiry into the Experiences of African First-time Fathers in Belgium.

Many African fathers face practices in their host countries that conflict with the conceptions of fatherhood in their countries of origin. They deal with negative stereotypes, including notions of paternal irresponsibility when it comes to embracing child care. This article looks at how exposure to the Belgian norms of fatherhood may redefine the fatherhood practices of African first-time fathers residing in Belgium. Drawing on a qualitative narrative approach, this article explores the perceptions and experiences of African migrant fathers in Belgium and examines how they adapt to a different fathering culture. The findings show that while African first-time fathers acknowledged their primary role as providers, they also embraced new practices that transgress defined gender lines in African culture. In the absence of a larger family support network, respondents face the responsibility of providing prenatal and postnatal support and sharing in child care responsibilities. Findings also shed light on how African fathers with European partners engage in shared decision-making and negotiate on core African values such as male circumcision.

A Proposal to Differentiate ACO, Asthma and COPD in Vietnam.

BACKGROUND: In low- and middle-income countries, such as Vietnam, the population is exposed to multiple risks, leading to frequent allergic asthma, COPD and their overlap (ACO). We aimed to differentiate asthma and COPD, so that recommended treatments can be applied. METHODS: We hypothesized that during life, the cumulative exposure to noxious particles increases the relative prevalence of COPD, while due to immuno-senescence, the prevalence of allergic asthma decreases with age. Among 568 patients with chronic respiratory symptoms, five phenotypes were defined, based on responsiveness to a bronchodilator (BD), diffusion capacity and cumulative smoking. Then the relative prevalence of each phenotype was related with age. RESULTS: the smoker BD irreversible patients were considered "COPD", while the full BD responders and non-smoking BD incomplete responders were "asthmatics". The other patients were ACO, distributed as "like-COPD" or "like-asthma", based on decreased or normal diffusion capacity. The relative prevalence of asthma, COPD and ACO were 26, 42 and 32% (18% "like-asthma", 14% "like-COPD"). CONCLUSION: Vietnamese patients with chronic respiratory symptoms were considered as falling into asthma or COPD groups, based on cumulative smoking, spirometry with reversibility and diffusion capacity. The relative prevalence of asthma and COPD were 44 and 56%, respectively, most of which did not require corticosteroids.

Lyl-1 regulates primitive macrophages and microglia development.

During ontogeny, macrophage populations emerge in the Yolk Sac (YS) via two distinct progenitor waves, prior to hematopoietic stem cell development. Macrophage progenitors from the primitive/"early EMP" and transient-definitive/"late EMP" waves both contribute to various resident primitive macrophage populations in the developing embryonic organs. Identifying factors that modulates early stages of macrophage progenitor development may lead to a better understanding of defective function of specific resident macrophage subsets. Here we show that YS primitive macrophage progenitors express Lyl-1, a bHLH transcription factor related to SCL/Tal-1. Transcriptomic analysis of YS macrophage progenitors indicate that primitive macrophage progenitors present at embryonic day 9 are clearly distinct from those present at later stages. Disruption of Lyl-1 basic helix-loop-helix domain leads initially to an increased emergence of primitive macrophage progenitors, and later to their defective differentiation. These defects are associated with a disrupted expression of gene sets related to embryonic patterning and neurodevelopment. Lyl-1-deficiency also induce a reduced production of mature macrophages/microglia in the early brain, as well as a transient reduction of the microglia pool at midgestation and in the newborn. We thus identify Lyl-1 as a critical regulator of primitive macrophages and microglia development, which disruption may impair resident-macrophage function during organogenesis.

Twenty-Four-Year Trends in Family and Regional Disparities in Fruit, Vegetable and Sugar-Sweetened Beverage Consumption among Adolescents in Belgium.

Dietary habits are influenced by various determinants that may evolve over time. This study aimed to examine, among adolescents in Belgium, trends in the dietary habits between 1990 and 2014 and to determine changes in family and regional disparities related to diet during this time period. In the 1990, 2002 and 2014 cross-sectional "Health Behaviour in School-aged Children" (HBSC) surveys, food consumption was estimated using a short Food Frequency Questionnaire. The Relative Index of Inequality (RII) enabled quantification of the gradients of inequality related to the family structure and to the region for non-daily fruit and vegetable and daily sugar-sweetened beverage (SSB) consumption. Between 1990 and 2014, the prevalence of non-daily fruit consumption increased from 27.7% to 60.6%, whereas the daily SSB consumption decreased from 58.9% to 34.8%. Over time, a downward trend in family disparities (p = 0.007) was observed for daily fruit consumption (RII: 1.58 (1.33-1.88) to 1.18 (1.13-1.23)). An upward trend in region-related disparities (p < 0.001) for SSB was found (RII: 1.15 (1.07-1.23) to 1.37 (1.28-1.47)). The overall trend of increasing disparities when dietary habits improved and decreasing disparities when dietary habits worsened highlights the need to implement actions that improve overall dietary habits while ensuring that disparities do not increase.

Experiences, views and needs of first-time fathers in pregnancy-related care: a qualitative study in south-East Nigeria.

BACKGROUND: Given the relevance of paternal involvement in maternal care, there is a need to prepare first-time fathers to participate in pregnancy and childbirth actively. This study explores the experiences and needs of first-time fathers; and how these influences their involvement during pregnancy and childbirth in Nigeria. METHODS: A descriptive qualitative study was conducted. Semi-structured interviews with 50 men recruited from rural and urban workplaces, hospitals, and markets, generated data used to explore the experiences, views and needs of first-time fathers' in pregnancy-related care in south-east Nigeria. All data were transcribed and analysed using thematic analysis. RESULTS: Six major themes were identified: gender roles, antenatal involvement, care costs and delivery choices, need to be informed, dealing with emotions, and dealing with the delivery day. The key finding reveals that inexperience and perceptions of gender roles greatly influenced the support provided by first-time fathers to their spouses and the support they received from their social support networks. Two primary needs were identified: need to be informed and the need to know about the cost of care in health settings. First-time fathers acknowledged the role of information on their decision making and final choices. CONCLUSION: Findings reveal the influence of gender norms, beliefs, and social support on first-time fathers' involvement in pregnancy and childbirth. This study also highlights the urgent need to provide informational support for first-time fathers and presents insights into what hospitals can do to achieve this need.

The protective effect of rural life on mite sensitization disappears among urban migrants in the South of Vietnam.

BACKGROUND: Rapid urbanization combined with rural migration to urban areas in southern Vietnam could be risk factors for allergen sensitization, contributing to chronic respiratory diseases (CRD). We aimed to evaluate the prevalence of mite sensitization and its relation to house dust characteristics among rural and urban native and migrating populations with CRD. METHODS: Rural (n = 19) and urban (n = 46) dwellings were defined on the basis of a home typology. Controls were western Belgian houses (n = 14). Besides the house characteristics, both endotoxin and mite allergens were measured in the settled dusts. The sensitization to mite allergens was defined by positive skin prick test (SPT) and concentration of specific IgE (sIgE)≥ 0.7 U/mL. The prevalence of mite sensitization was evaluated among 610 patients with CRD and compared according to both their home types and places of birth and residences. RESULTS: The concentration of endotoxin (but not mite allergen) was higher in rural compared to urban dusts (440 (95%CI: 314-566) versus 170 (95%CI: 115-226) EU/mg; p < 0.0001). The prevalence of positive sIgE to Der p1 and Der p2 was significantly lower in rural (9% and 5%) compared to urban (15% and 9%) population, consistent with the positive SPT to mite (14% and 21%, respectively). Among the urban migrants, the risk of mite sensitization (SPT) was higher compared to the rural natives (OR: 1.79 (1.02-3.15), p < 0.05) and not different to the urban ones (OR: 1.35 (0.82-2.23) p NS). CONCLUSION: In Vietnam, associated with higher endotoxin (but not allergen) dust concentrations, the risk of mite sensitization was lower in rural compared to the native urban population, but this protective effect could disappear among rural to urban migrants.

Toll-like receptor 2 expression on c-kit+ cells tracks the emergence of embryonic definitive hematopoietic progenitors.

Hematopoiesis in mammalian embryos proceeds through three successive waves of hematopoietic progenitors. Since their emergence spatially and temporally overlap and phenotypic markers are often shared, the specifics regarding their origin, development, lineage restriction and mutual relationships have not been fully determined. The identification of wave-specific markers would aid to resolve these uncertainties. Here, we show that toll-like receptors (TLRs) are expressed during early mouse embryogenesis. We provide phenotypic and functional evidence that the expression of TLR2 on E7.5 c-kit+ cells marks the emergence of precursors of erythro-myeloid progenitors (EMPs) and provides resolution for separate tracking of EMPs from primitive progenitors. Using in vivo fate mapping, we show that at E8.5 the Tlr2 locus is already active in emerging EMPs and in progenitors of adult hematopoietic stem cells (HSC). Together, this data demonstrates that the activation of the Tlr2 locus tracks the earliest events in the process of EMP and HSC specification.

Ontogenic Changes in Hematopoietic Hierarchy Determine Pediatric Specificity and Disease Phenotype in Fusion Oncogene-Driven Myeloid Leukemia.

Fusion oncogenes are prevalent in several pediatric cancers, yet little is known about the specific associations between age and phenotype. We observed that fusion oncogenes, such as ETO2-GLIS2, are associated with acute megakaryoblastic or other myeloid leukemia subtypes in an age-dependent manner. Analysis of a novel inducible transgenic mouse model showed that ETO2-GLIS2 expression in fetal hematopoietic stem cells induced rapid megakaryoblastic leukemia whereas expression in adult bone marrow hematopoietic stem cells resulted in a shift toward myeloid transformation with a strikingly delayed in vivo leukemogenic potential. Chromatin accessibility and single-cell transcriptome analyses indicate ontogeny-dependent intrinsic and ETO2-GLIS2-induced differences in the activities of key transcription factors, including ERG, SPI1, GATA1, and CEBPA. Importantly, switching off the fusion oncogene restored terminal differentiation of the leukemic blasts. Together, these data show that aggressiveness and phenotypes in pediatric acute myeloid leukemia result from an ontogeny-related differential susceptibility to transformation by fusion oncogenes. SIGNIFICANCE: This work demonstrates that the clinical phenotype of pediatric acute myeloid leukemia is determined by ontogeny-dependent susceptibility for transformation by oncogenic fusion genes. The phenotype is maintained by potentially reversible alteration of key transcription factors, indicating that targeting of the fusions may overcome the differentiation blockage and revert the leukemic state.See related commentary by Cruz Hernandez and Vyas, p. 1653.This article is highlighted in the In This Issue feature, p. 1631.

Do Communities Really "Direct" in Community-Directed Interventions? A Qualitative Assessment of Beneficiaries' Perceptions at 20 Years of Community Directed Treatment with Ivermectin in Cameroon.

Recent studies in Cameroon after 20 years of implementation of the Community Directed Treatment with ivermectin (CDTI) strategy, revealed mixed results as regards community ownership. This brings into question the feasibility of Community Directed Interventions (CDI) in the country. We carried out qualitative surveys in 3 health districts of Cameroon, consisting of 11 individual interviews and 10 Focus Group Discussions (FGDs) with specific community members. The main topic discussed during individual interviews and FGDs was about community participation in health. We found an implementation gap in CDTI between the process theory in the 3 health districts. Despite this gap, community eagerness for health information and massive personal and financial adhesion to interventions that were perceived important, were indicators of CDI feasibility. The concept of CDI is culturally feasible in rural and semi-urban settlements, but many challenges hinder its actual implementation. In the view of community participation as a process rather than an intervention, these challenges include real dialogue with communities as partners, dialogue and advocacy with operational level health staff, and macroeconomic and political reforms in health, finance and other associated sectors.

Transforming child and youth mental health care: ACCESS Open Minds New Brunswick in the rural Francophone region of the Acadian Peninsula.

AIM: This paper describes how the transformation of youth mental health services in the rural Francophone region of the Acadian Peninsula in New Brunswick, Canada, is meeting the five objectives of ACCESS Open Minds. METHODS: Implementation of the ACCESS Open Minds framework of care in the Acadian Peninsula of New Brunswick began in 2016 at a well-established volunteer centre and community-based mental health organization. Through focus groups with youth aged 14 to 22 (n = 13), community mapping was used to describe the youth-related mental health service transformation, followed by thematic analysis, validation by member checking and triangulation. RESULTS: Preliminary results show a generally successful implementation of the ACCESS Open Minds model, as evidenced by the transformation of mental health service provision, the enhancement of capacity in human resources and the participation of youth. Transformation was evidenced across the five objectives of mental healthcare of ACCESS Open Minds, albeit to variable extents. Several facilitating factors and challenges are identified based on youths' accounts. CONCLUSIONS: It is possible to successfully implement the ACCESS Open Minds model among francophones living in a minority setting and despite the constraints of a rural area. Most key components of the framework were implemented with high program fidelity. The rural context presents unique challenges that require creative and effective use of resources, while offering opportunities that arise from a culture of resourcefulness and collaboration.

Barriers to the National Onchocerciasis Control Programme at operational level in Cameroon: a qualitative assessment of stakeholders' views.

BACKGROUND: The global burden of onchocerciasis is the heaviest in sub-Saharan Africa. Studies have shown the importance of the role of Community-Directed Distributors (CDDs) and nurses in onchocerciasis control, but little is known about their experience in implementing onchocerciasis control programmes. Our aim was to document the barriers that CDDs and local health administrators face in implementing onchocerciasis control activities. METHODS: We conducted a qualitative survey consisting of 16 in-depth interviews and 8 focus group discussions (FGDs) across three health districts of Cameroon. We interviewed a total of 9 local health officials at the district and Health Area levels, and 7 CDDs. Eight FGDs were conducted with CDDs and Health Committee members. RESULTS: The major barriers to the implementation of Community Directed Treatment with Ivermectin that we identified were linked and interrelated. Examples of these barriers included: contextual factors (geographical and cultural background), top-to-bottom planning, insufficient human and material resources, and lack of transparency in the management of the programme's funds. CONCLUSIONS: The CDTI at operational level still faces many obstacles which negatively affect therapeutic coverages. This can lead to the non-adhesion of the communities to the programme, consequently jeopardizing the sustainability of the onchocerciasis elimination programme. We recommend that the national programme planners put in place a transparent management and planning system for onchocerciasis elimination activities, with better communication with local programme stakeholders.

Socioeconomic Disparities in Diet Vary According to Migration Status among Adolescents in Belgium.

Little information concerning social disparities in adolescent dietary habits is currently available, especially regarding migration status. The aim of the present study was to estimate socioeconomic disparities in dietary habits of school adolescents from different migration backgrounds. In the 2014 cross-sectional "Health Behavior in School-Aged Children" survey in Belgium, food consumption was estimated using a self-administrated short food frequency questionnaire. In total, 19,172 school adolescents aged 10-19 years were included in analyses. Multilevel multiple binary and multinomial logistic regressions were performed, stratified by migration status (natives, 2nd- and 1st-generation immigrants). Overall, immigrants more frequently consumed both healthy and unhealthy foods. Indeed, 32.4% of 1st-generation immigrants, 26.5% of 2nd-generation immigrants, and 16.7% of natives consumed fish ≥two days a week. Compared to those having a high family affluence scale (FAS), adolescents with a low FAS were more likely to consume chips and fries ≥once a day (vs.

Feelings about the timing of first sexual intercourse and health-related quality of life among adolescents.

BACKGROUND: Early sexual intercourse (SI) may have long-lasting negative impacts on health-related quality of life (HRQoL). So far, these impacts have been studied using age for defining early SI instead of feelings about its timing. The present study examined the association between feelings about the timing of first SI and current HRQoL. METHODS: Data came from the 2014 cross-sectional Health Behaviour in School-aged Children (HBSC) study in French-speaking Belgium. Among participants aged 16-20 years who already had SI, 1778 were included in analyses. Univariate and multivariate logistic regressions were performed, including potential confounders. RESULTS: One quarter of adolescents (26.4%) had poor HRQoL, 19.8% expressed a negative feeling about the timing of first SI and 19.6% did not think about it. Compared with adolescents who thought first SI happened at the right time or wished it had happened sooner, adolescents who had a negative feeling about the timing and those who did not think about it were more likely to have a poor HRQoL (cOR = 1.67 (1.28-2.17) and cOR = 1.37 (1.05-1.80), respectively). After adjustment, associations were no more significant (aOR = 1.22 (0.91-1.63) and aOR = 1.22 (0.91-1.64)). Sex disparity in expressing a negative feeling mostly explained the difference between crude and adjusted analyses. CONCLUSION: Further research is needed to better understand such a complex relationship. The high proportion of adolescents having poor HRQoL and negative feeling about the timing of first SI shows how important it is to find out effective prevention for both domains.

Environmental correlates of physical activity among children 10 to 13 years old in Wallonia (Belgium).

BACKGROUND: In Belgium, as in many other countries, the juvenile practice of physical activity is insufficient. A growing attention has been paid to environmental factors that may influence physical activity but with inconsistent findings. This study aims to estimate the association between daily life environment characteristics and physical activity among children 10 to 13 years old in Wallonia (Belgium). METHODS: Data were collected using a self-administered questionnaire among 1940 children (HBSC survey). Associations between factors related to the children's living environment and physical activity (vigorous physical activity (VPA) ≥ twice a week; global physical activity (GPA) defined as VPA ≥ twice a week and moderate-to-vigorous physical activity ≥1 h/day) were estimated using logistic regressions adjusted for potential confounders. RESULTS: Nearly three-quarters of the children practiced VPA ≥ twice a week, but only one in five practiced GPA consistent with recommendations. After adjustment, children living in a neighborhood with playgrounds or parks were more likely to achieve a recommended level of GPA (OR: 1.34 [1.04-1.73]), as were children who reported that other youngsters were present in their neighborhood with whom they could play outside (OR: 1.50 [1.12-1.99]). The presence of neighborhood children was also positively associated with VPA (OR: 1.80 [1.42-2.29]); in stratified analyses, the association was significant only among boys (OR: 1.95 [1.34-2.82]). Moreover, and only in girls (OR: 1.66 [1.10-2.49]), a feeling of safety in one's neighborhood was positively associated with VPA. No association was found between VPA and the existence of a yard or a garden at home to go playing outside. CONCLUSION: Our results argue for developing actions aimed at creating living environments more favorable to children's daily physical activity. More specifically, they help better understand the environment of Belgian children and thus contribute to better identify their needs.
