[PMID: 38561596 DOI: 10.1111/ijn.13253] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2023] [Revised: 01/04/2024] [Accepted: 03/09/2024] [Indexed: 04/04/2024]
Abstract
AIM The research was conducted to measure the effect of health literacy-grounded web-based education program on health literacy, nutrition and exercise behaviours in adolescents. BACKGROUND The increasing prevalence of obesity in adolescents is explained by a sedentary lifestyle and unhealthy diet. Health literacy is essential for adolescents to maintain their healthy behaviours. METHODS The research was conducted as a parallel group randomized controlled trial. The study was completed by 114 adolescents (experimental = 42, control = 72). The Personal Information Form, the Health Literacy Scale for School-Age Children and the Nutrition and Exercise Subscales were used to collect data. A web-based education program was implemented. Two-way mixed design ANOVA with Bonferroni test was used to examine the group, time and group * time interaction of the measurements. RESULTS There was no statistically significant difference between the experimental and control groups regarding health literacy level, nutrition and exercise behaviours pre-test mean scores (p > 0.05). In the post-test, the mean scores of health literacy and nutrition behaviours in the experimental group were higher than the control group (p < 0.001). However, there was no significant difference in exercise behaviours (p > 0.05). The power and effect size in mean scores changes for health literacy (99.8%, η2 = 0.039) and nutrition (99.8%, η2 = 0.039) were moderate. CONCLUSION The study concluded that health literacy-grounded web-based education program increased the health literacy levels of adolescents and improved their nutritional behaviours; however, there was no sufficient change in exercise behaviours.

Effectiveness of Intervention Strategies to Increase Adolescents' Physical Activity and Reduce Sedentary Time in Secondary School Settings, Including Factors Related to Implementation: A Systematic Review and Meta-Analysis. SPORTS MEDICINE - OPEN 2024; 10:25. [PMID: 38472550 DOI: 10.1186/s40798-024-00688-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/20/2022] [Accepted: 02/21/2024] [Indexed: 03/14/2024]
Abstract
BACKGROUND Globally, just one in five adolescents meet physical activity guidelines and three-quarters of the school day is spent sitting. It is unclear which types of school-based interventions strategies increase physical activity and reduce sedentary time among adolescents, or how these interventions are implemented influences their effectiveness. OBJECTIVE The three aims of our systematic review were to (a) identify intervention strategies used within secondary school settings to improve students' movement behaviours throughout school-based initiatives, delivered at or by the school; (b) determine the overall effect of the interventions (meta-analysis) on physical activity (all intensities), sedentary time, cognitive/academic, physical health and/or psychological outcomes; and (c) describe factors related to intervention implementation. METHODS Searches were conducted in MEDLINE complete, EMBASE, CINAHL, SPORTDiscus, APA PsycINFO, and ERIC in January 2023 for studies that (a) included high school-aged adolescents; (b) involved a school-based intervention to increase physical activity and/or decrease sedentary time; and (c) were published in English. Reported effects were pooled in meta-analyses where sufficient data were obtained. RESULTS Eighty-five articles, representing 61 interventions, met the inclusion criteria, with 23 unique intervention strategies used. Interventions that involved whole-school approaches (i.e., physical activity sessions, environmental modifications, teacher training, peer support and/or educational resources) were favourably associated with most of the outcomes. The meta-analyses showed: (a) non-significant effects for sedentary time (Standardized mean difference [SMD] = -0.02; 95%CI, -0.14, 0.11), physical activity at all intensities (light: SMD= -0.01; 95%CI, -0.08, 0.05; moderate: SMD = 0.06; 95%CI, -0.09, 0.22; vigorous: SMD = 0.08; 95%CI, -0.02, 0.18; moderate-to-vigorous: SMD = 0.05; 95%CI, -0.01, 0.12) and waist circumference (SMD = 0.09; 95%CI, -0.03, 0.21), and (b) a small statistically significant decrease in body mass index (SMD= -0.09, 95%CI -0.16, -0.0). Factors related to intervention implementation were reported in 51% of the articles. CONCLUSION While some intervention approaches demonstrated promise, small or null effects were found in meta-analyses. Future school-based interventions should utilize a whole-school approach designed to increase adolescents' activity across the day. Consistent reporting of implementation will increase understanding of how interventions are adopted, implemented and sustained. REGISTRATION PROSPERO (CRD42020169988).

Abstract
Despite the many health benefits of physical activity (PA) and healthy eating (HE) most adolescents do not meet current guidelines which poses future health risks. This review aimed to (1) identify whether adolescent PA and HE interventions show promise at promoting behaviour change and maintenance, (2) identify which behaviour change techniques (BCTs) are associated with promising interventions, and (3) explore the optimal approaches to training deliverers of adolescent PA/HE interventions. Nine databases were searched for randomised controlled, or quasi-experimental, trials targeting 10-19 year olds, with a primary aim to increase PA/HE, measured at baseline and at least six months post-intervention, in addition to papers reporting training of deliverers of adolescent PA/HE interventions. Included were seven PA studies, three HE studies and four studies targeting both, with two training papers. For PA studies, two were promising post-intervention with two promising BCTs, and five were promising for maintenance with two promising BCTs. For HE studies, three were promising at post-intervention and four at maintenance, both with four promising BCTs. There is preliminary evidence that interventions support adolescents to improve their PA and HE behaviours over a period of at least six months.

Abstract
The purpose of this study was to summarize the evidence from studies conducted on adolescents, evaluating educational nutrition interventions for the modification of food consumption through controlled trials based on behavior change theories or models and implemented in school settings. A systematic search was carried out through PubMed and ERIC databases between November and December 2020, and updated in February 2023; English-language keywords were used, and no publication date limits were applied. Two authors independently performed the search, data extraction, data synthesis and risk of bias assessment. Twelve studies meeting the inclusion criteria were included. The interventions were based on different theories; the most used was the Social Cognitive Theory. Eleven of the twelve studies showed favorable modifications in the consumption of at least two of the food groups. Most studies were at low risk of bias, and only one was classified as high risk. It is concluded that educational nutrition interventions based on behavior change theories/models and implemented in the school setting influence positive changes in adolescents eating behavior.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:6940.

Abstract
Physical activity (PA) and sedentary behaviour (SB) are important components of physical behaviour associated with long-term health outcomes. Environmental and cultural factors may influence physical behaviour. To explore full day PA and SB in children and adolescents (2-18 years old) in the Middle East, a systematic literature review was performed including 183 journal articles. A wide range of PA and SB outcomes were reported, in some cases making synthesis of results difficult. As a consequence, results were generally reported narratively (MVPA time, total PA, SB time). Meta-regression of daily step count revealed females took 4600 fewer steps than males, with 3000 fewer steps on weekdays than weekends, and overweight individuals taking 2800 fewer steps/day. Steps decreased with age. Meta-regression for TV viewing time demonstrated an increase by 0.04 h per year of age. Even though environmental and cultural conditions may be different, PA and SB of children and adolescents in the Middle East were largely comparable to those of Europeans and North Americans. The wide range of data collection instruments used (both self-report questionnaire and body-worn devices) and heterogeneity of data made synthesis of reported data across studies very difficult, suggesting a need for greater standardisation of data collection methods.

School-based Mental Health Interventions Targeting Depression or Anxiety: A Meta-analysis of Rigorous Randomized Controlled Trials for School-aged Children and Adolescents. J Youth Adolesc 2023; 52:195-217.

Abstract
Past meta-analyses in mental health interventions failed to use stringent inclusion criteria and diverse moderators, therefore, there is a need to employ more rigorous methods to provide evidence-based and updated results on this topic. This study presents an updated meta-analysis of interventions targeting anxiety or depression using more stringent inclusion criteria (e.g., baseline equivalence, no significant differential attrition) and additional moderators (e.g., sample size and program duration) than previous reviews. This meta-analysis includes 29 studies of 32 programs and 22,420 students (52% female, 79% White). Among these studies, 22 include anxiety outcomes and 24 include depression outcomes. Overall, school-based mental health interventions in grades K-12 are effective at reducing depression and anxiety (ES = 0.24, p = 0.002). Moderator analysis shows that improved outcomes for studies with anxiety outcomes, cognitive behavioral therapy, interventions delivered by clinicians, and secondary school populations. Selection modeling reveals significant publication and outcome selection bias. This meta-analysis suggests school-based mental health programs should strive to adopt cognitive behavioral therapy and deliver through clinicians at the secondary school level where possible.

Abstract
Objective To evaluate the effectiveness of Sahtak bi Sahnak on dietary knowledge and adherence to dietary guidelines in Lebanese adolescents. Design/setting A cluster randomised controlled trial was conducted in public and private secondary schools located in urban and rural regions in Lebanon. Participants Sixteen secondary schools including 1,572 adolescents were randomly assigned to the intervention (n = 739) or control group (n = 833). Intervention Sahtak bi Sahnak is an educational school-based intervention dedicated to improving dietary adherence to nutritional guidelines, increasing the level of dietary knowledge, and preventing the development of obesity during adolescence. It was systematically designed based on the Intervention Mapping framework. The total length of the intervention was around seven educational sessions, until all of the 11 lessons were covered. Each education session lasted 20-40 min. Main Outcome Measures Dietary knowledge and adherence levels were measured at baseline and post-intervention using validated questionnaires. Statistical Analysis Multivariate multilevel regression models were used to examine intervention effects on outcomes, controlled for background characteristics (i.e., age, gender, location, type of school, grade, BMI z-score). Results The intervention group showed significant improvements in total dietary knowledge (B = 12.74, p < 0.001) and intake of healthy items (B = 1.89, p < 0.001), compared to the control group. Intake of unhealthy items decreased significantly (B = -1.43, p < 0.001), compared to the control group. These results were adjusted for age, gender, type of school, location, BMI z-score, study group, and score at baseline. Conclusion and Implications Sahtak bi Sahnak is an effective and culturally appropriate school-based intervention for targeting diet among a variety of Lebanese adolescents.

Abstract
BACKGROUND Health indicators are used in different settings to monitor health outcomes. Child and adolescent health is arguably one of the most important areas for the application of indices and indicators in prevention and health promotion. Although single health indicators may be better suited to display the complexity of the health status and its determinants, a selected set of indicators will still offer a complex picture. Therefore, it is argued that a group of indicators combined into an index may offer a pragmatic tool that is easier to use in order to inform stakeholders. METHODS A scoping review was conducted to identify and describe health indices that monitor and evaluate health of children and adolescents and to appraise the quality and value of the identified indices that may guide the further applications of these indices in particular settings. The three bibliographic databases MEDLINE, EMBASE and PsycINFO were searched and a double screening of titles and abstracts as well as double screening of full texts was performed. Indices contained in these studies were analysed in terms of focus and composition and evaluated in terms of quality criteria. RESULTS The scoping review identified 36 eligible studies with 18 health indices in six thematic categories. Of the identified indices, seven indices focus on anthropometrical variables, three indices focus on special aspects of newborns and five indices focus on oral health. One index assesses "healthy lifestyle" and one "functional ability" whereas one index a combination of different aspects. Most indices are calculated by using primary health data. CONCLUSIONS Alone or in combination with single sets of indicators, indices in six major thematic domains may be used as pragmatic tools for monitoring children's and adolescents´ health and the evaluation of interventions in health promotion and prevention settings.

Abstract
OBJECTIVES This study was conducted to examine the effect of healthy lifestyle beliefs on their attitudes toward physical activity, nutrition, exercise, and weight-related self-efficacy lifestyles in Turkish adolescents. METHODS This study used a methodological and descriptive design. The study was conducted with 445 adolescents aged 13-18 years. The data were collected using a Descriptive Information Form, the Healthy Lifestyle Beliefs Scale for Adolescents, the Nutrition Exercise Attitudes Scale, and the Attitudes Toward Physical Activity Scale. Mean and percentage values, t-test, ANOVA test, and linear regression analysis were used in the analysis of the research data. RESULTS A statistically significant difference was found between adolescents' obesity status, paternal educational level, maternal educational level, income status, and the mean scores obtained for healthy lifestyle beliefs, nutrition and exercise attitudes, physical activity attitudes, and weight-related self-efficacy, as well as between sex and mean scores for attitudes toward nutrition, exercise, and physical activity. In the model created with regression analysis, it was found that the adolescents' healthy lifestyle beliefs and sociodemographic variables explained 96.3% of their attitudes toward nutrition and exercise, 93.6% of physical activity attitudes, and 96.5% of weight-related self-efficacy levels, with statistical significance. CONCLUSION According to the results of the study, healthy lifestyle beliefs are an important predictor of adolescents' attitudes toward nutrition, exercise, and physical activity as well as their weight-related self-efficacy. We recommend that school nurses consider healthy lifestyle beliefs when creating intervention programs for adolescents .

Abstract
PURPOSE This study was carried out to determine the effect of an obesity prevention program on children's eating behaviors, food addiction, physical activity, and obesity prevalence. DESIGN AND METHODS A pretest-posttest quasi-experimental design was used in the study. The study was conducted with a total of 128 students, including 55 in the intervention and 73 in the control groups. The obesity prevention program was implemented in the intervention group, and a routine curriculum training program was followed in the control group. The study data were collected before the intervention and in the third, sixth, and fifteenth months after the completion of the intervention. The data were evaluated using the chi-square test, McNeamer test, Cochrane Q test, multivariate analysis of variance in repeated measures, the Bonferroni adjusted paired t-test, power analysis, effect size, and regression analysis. RESULTS At the end of the study, it was determined that the body mass index values and food addiction rates of the students in the intervention group were lower than those of the students in the control group (p < .05). There was a significant difference between the mean scores of the students in the intervention and control groups obtained from the eating behavior questionnaire and the physical activity questionnaire in terms of time, group, and group * time interaction (p < .05). Also, the intervention program was found to have a large effect size (0.39) and a strong effect (0.85) on body mass index. CONCLUSION The obesity prevention intervention program was found to be effective in increasing children's positive eating behaviors and mean physical activity score and decreasing food addiction rates and body mass index values. PRACTICE IMPLICATIONS We recommend that the intervention program implemented in this study should be used widely in the curriculum of the Ministry of Education. This program shows that the school nurse is effective in preventing obesity in children. For this reason, there should be a school nurse in schools for implementing health-promoting education programs.

Abstract
BACKGROUND Physical activity among children and adolescents is associated with lower adiposity, improved cardio-metabolic health, and improved fitness. Worldwide, fewer than 30% of children and adolescents meet global physical activity recommendations of at least 60 minutes of moderate to vigorous physical activity per day. Schools may be ideal sites for interventions given that children and adolescents in most parts of the world spend a substantial amount of time in transit to and from school or attending school. OBJECTIVES The purpose of this review update is to summarise the evidence on effectiveness of school-based interventions in increasing moderate to vigorous physical activity and improving fitness among children and adolescents 6 to 18 years of age. Specific objectives are: • to evaluate the effects of school-based interventions on increasing physical activity and improving fitness among children and adolescents; • to evaluate the effects of school-based interventions on improving body composition; and • to determine whether certain combinations or components (or both) of school-based interventions are more effective than others in promoting physical activity and fitness in this target population. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, CINAHL, PsycINFO, BIOSIS, SPORTDiscus, and Sociological Abstracts to 1 June 2020, without language restrictions. We screened reference lists of included articles and relevant systematic reviews. We contacted primary authors of studies to ask for additional information. SELECTION CRITERIA Eligible interventions were relevant to public health practice (i.e. were not delivered by a clinician), were implemented in the school setting, and aimed to increase physical activity among all school-attending children and adolescents (aged 6 to 18) for at least 12 weeks. The review was limited to randomised controlled trials. For this update, we have added two new criteria: the primary aim of the study was to increase physical activity or fitness, and the study used an objective measure of physical activity or fitness. Primary outcomes included proportion of participants meeting physical activity guidelines and duration of moderate to vigorous physical activity and sedentary time (new to this update). Secondary outcomes included measured body mass index (BMI), physical fitness, health-related quality of life (new to this update), and adverse events (new to this update). Television viewing time, blood cholesterol, and blood pressure have been removed from this update. DATA COLLECTION AND ANALYSIS: Two independent review authors used standardised forms to assess each study for relevance, to extract data, and to assess risk of bias. When discrepancies existed, discussion occurred until consensus was reached. Certainty of evidence was assessed according to GRADE. A random-effects meta-analysis based on the inverse variance method was conducted with participants stratified by age (children versus adolescents) when sufficient data were reported. Subgroup analyses explored effects by intervention type. MAIN RESULTS Based on the three new inclusion criteria, we excluded 16 of the 44 studies included in the previous version of this review. We screened an additional 9968 titles (search October 2011 to June 2020), of which 978 unique studies were potentially relevant and 61 met all criteria for this update. We included a total of 89 studies representing complete data for 66,752 study participants. Most studies included children only (n = 56), followed by adolescents only (n = 22), and both (n = 10); one study did not report student age. Multi-component interventions were most common (n = 40), followed by schooltime physical activity (n = 19), enhanced physical education (n = 15), and before and after school programmes (n = 14); one study explored both enhanced physical education and an after school programme. Lack of blinding of participants, personnel, and outcome assessors and loss to follow-up were the most common sources of bias. Results show that school-based physical activity interventions probably result in little to no increase in time engaged in moderate to vigorous physical activity (mean difference (MD) 0.73 minutes/d, 95% confidence interval (CI) 0.16 to 1.30; 33 studies; moderate-certainty evidence) and may lead to little to no decrease in sedentary time (MD -3.78 minutes/d, 95% CI -7.80 to 0.24; 16 studies; low-certainty evidence). School-based physical activity interventions may improve physical fitness reported as maximal oxygen uptake (VO₂max) (MD 1.19 mL/kg/min, 95% CI 0.57 to 1.82; 13 studies; low-certainty evidence). School-based physical activity interventions may result in a very small decrease in BMI z-scores (MD -0.06, 95% CI -0.09 to -0.02; 21 studies; low-certainty evidence) and may not impact BMI expressed as kg/m² (MD -0.07, 95% CI -0.15 to 0.01; 50 studies; low-certainty evidence). We are very uncertain whether school-based physical activity interventions impact health-related quality of life or adverse events. AUTHORS' CONCLUSIONS Given the variability of results and the overall small effects, school staff and public health professionals must give the matter considerable thought before implementing school-based physical activity interventions. Given the heterogeneity of effects, the risk of bias, and findings that the magnitude of effect is generally small, results should be interpreted cautiously.

Abstract
Adolescence is a critical life phase for mental health and anxiety an emerging challenge for adolescents. Psychoeducational interventions to promote mental health literacy (MHL) on anxiety in adolescents are needed. This study aimed to test the primary outcome of a future full-scale trial: improvement of adolescents' anxiety MHL components on recognition, prevention strategies, and self-help strategies. A sample of 38 adolescents, 24 (63.2%) females and 14 (36.8%) males, with an average age of 14.50 years (SD = 0.89) participated in this study. Each class was allocated to the intervention group (IG, n = 21) or the waiting list control group (WLCG, n = 17) with single-blinded randomization. MHL was assessed using the QuALiSMental. The ProLiSMental psychoeducational intervention consists of four or eight weekly sessions of 90 or 45 min for adolescents, using different active pedagogical methods and techniques. There also are initial and final sessions with adolescents, legal guardians, and teachers. There was a significant improvement with a small to relatively strong effect size in many dimensions of anxiety MHL components. This study suggests the progression to the full-scale trial and values the important role of mental health and psychiatric nurses in the adolescents' empowerment for MHL in schools.

Abstract
BACKGROUND The objective was to evaluate a 5-week nutrition education programme (ACTION) in fifth-grade schoolchildren in Austria on free sugar intake, nutrition-related knowledge (NRK) and with the RE-AIM framework on the overall public health impact. METHODS A prospective case-controlled cohort (pre-post design) from seven secondary schools in Vienna tested programme efficacy. NRK was assessed with a 20-item questionnaire and dietary behaviour and free sugar intake with a semi-quantitative Food Frequency Questionnaire. A total of 12 intervention classes (IG) received the programme, conducted by teachers and integrated in the curriculum, and 6 control classes followed their usual curriculum. RESULTS In 344 children, aged 10.4 (0.8) years, free sugar intake decreased significantly over time in IG by 13% (P=0.001) with a group difference of -10.1 (95% CI -18.8, -1.5; P=0.021) g/day. The food groups 'sweets & pastries', 'soft drinks', 'fast food' and 'salty snacks' mainly contributed to this reduction. Moreover, NRK increased significantly over time in IG with a group difference of 9.0% of correct answers (95% CI 5.8, 12.2; P<0.001; Cohen's d 0.57). The programme was disseminated to 10% of fifth-grade classrooms in Austrian secondary schools and to 12% in Vienna. CONCLUSIONS The ACTION programme shows potential for public health impact with improving dietary behaviour as free sugar intake, NRK, and its dissemination. It required a minimum of money per schoolchild as the programme was conducted by teachers and was integrated in the curriculum.

Abstract
BACKGROUND Much is not known about the efficacy of interventions to prevent poor mental health outcomes in young people by targeting either the general population (universal prevention) or asymptomatic individuals with high risk of developing a mental disorder (selective prevention). METHODS We conducted a PRISMA/MOOSE-compliant systematic review and meta-analysis of Web of Science to identify studies comparing post-test efficacy (effect size [ES]; Hedges' g) of universal or selective interventions for poor mental health outcomes versus control groups, in samples with mean age <35 years (PROSPERO: CRD42018102143). Measurements included random-effects models, I2 statistics, publication bias, meta-regression, sensitivity analyses, quality assessments, number needed to treat, and population impact number. RESULTS 295 articles (447,206 individuals; mean age = 15.4) appraising 17 poor mental health outcomes were included. Compared to control conditions, universal and selective interventions improved (in descending magnitude order) interpersonal violence, general psychological distress, alcohol use, anxiety features, affective symptoms, other emotional and behavioral problems, consequences of alcohol use, posttraumatic stress disorder features, conduct problems, tobacco use, externalizing behaviors, attention-deficit/hyperactivity disorder features, and cannabis use, but not eating-related problems, impaired functioning, internalizing behavior, or sleep-related problems. Psychoeducation had the highest effect size for ADHD features, affective symptoms, and interpersonal violence. Psychotherapy had the highest effect size for anxiety features. CONCLUSION Universal and selective preventive interventions for young individuals are feasible and can improve poor mental health outcomes.

Abstract
Understanding the social and environmental influencers of eating behaviours has the potential to improve health outcomes for young people. This review aims to explore the effectiveness of school nutrition interventions and the perceptions of young people experiencing a nutrition focused intervention or change in school food policy. A comprehensive systematic search identified studies published between 1 December 2007 to 20 February 2020. Twenty-seven studies were included: 22 quantitative studies of nutrition related outcomes and five qualitative studies reporting views and perceptions of young people (combined sample of 22,138 participants, mean ages 12-18 years). The primary outcome was nutrition knowledge/dietary behaviours, with secondary outcomes exploring body mass index (BMI) and wellbeing. Due to the heterogeneity of studies, a narrative results description is presented. The findings demonstrate that school nutrition programmes can be effective in reducing sugar, sugar sweetened beverages (SSB) and saturated fat and increasing fruit and vegetable (FV) intake. The lived experiences of young people in a school context provide valuable insights that should be considered in the development of effective school food policy and interventions. This review affirms the significant role that schools can play in supporting good nutrition in all young people and provides opportunities to inform the school food agenda.

Abstract
BACKGROUND Hidden hunger (micronutrient deficiencies) among adolescents are linked to impaired physical growth, poor cognitive function, low resistance to infection as well as degenerative and chronic diseases at later age. To prevent these deleterious impacts of hidden hunger, effective intervention strategy that improves nutrition knowledge and promotes healthy food choices among this age-group becomes imperative. The intervention was to evaluate the impact of a 14-page locally developed nutrition education aids on the teenagers' knowledge of the functions, food sources and deficiencies of some micronutrients and their food choices. METHODS A one group pre-and post-intervention quasi-experimental study design was conducted with 869 adolescents (13-17 years) selected using multi-stage sampling technique in public secondary schools in a suburb of Nigeria. Using the instructional material development guidelines, the nutrition education aids were developed with nutrition facts, pictures of staple micronutrients-rich foods, and computer graphics. Baseline (pre-intervention) knowledge of nutrition and practice of food choices in relation to micronutrients were determined before exposing the students to the developed nutrition education aids and reassessing (post-intervention) them after 6 months. Data obtained were subjected to paired samples t-test using SPSS version 21. RESULTS The adolescents were mostly females (58.92%) aged 16-17 years (53.62%). There was significantly (p < 0.05) higher mean knowledge scores of general nutrition (65.77 vs. 39.61%) and food sources of nutrients (82.26 vs. 66.87%) at post-intervention compared to pre-intervention. Also, the mean knowledge of functions and deficiencies of vitamin C, folic acid, iron, calcium, and zinc were significantly (p < 0.05) higher at post-intervention than at pre-intervention. The study further revealed percentage increase in the proportion of respondents who consumed meat (27.72%), mango (128.20%), watermelon (152.29%), carrot (336.34%) and leafy vegetables (85.56%) daily after the intervention. In addition, the percentage of students who rarely consumed all the studied micronutrient-rich foods decreased after the intervention. CONCLUSION The intervention strategy increased the nutrition knowledge and the consumption of some micronutrients-rich food sources among the adolescents. The developed nutrition education aids are recommended for use in the fight to reduce/eradicate hidden hunger among adolescents in Nigeria.

Abstract
An effective behavior change program is the first line of prevention for youth obesity. However, effectiveness in prevention of adolescent obesity requires several approaches, with special attention paid to disordered eating behaviors and psychological support, among other environmental factors. The aim of this systematic review is to compare the impact of two types of obesity prevention programs, inclusive of behavior change components, on weight outcomes. "Energy-balance" studies are aimed at reducing calories from high-energy sources and increasing physical activity (PA) levels, while "shared risk factors for obesity and eating disorders" focus on reducing disordered eating behaviors to promote a positive food and eating relationship. A systematic search of ProQuest, PubMed, PsycInfo, SciELO, and Web of Science identified 8825 articles. Thirty-five studies were included in the review, of which 20 regarded "energy-balance" and 15 "shared risk factors for obesity and eating disorders". "Energy-balance" studies were unable to support maintenance weight status, diet, and PA. "Shared risk factors for obesity and eating disorders" programs also did not result in significant differences in weight status over time. However, the majority of "shared risk factors for obesity and eating disorders" studies demonstrated reduced body dissatisfaction, dieting, and weight-control behaviors. Research is needed to examine how a shared risk factor approach can address both obesity and eating disorders.

Abstract
OBJECTIVES Interventions for child obesity prevention are needed and it is unclear whether evidence from nonrandomized intervention studies is adequate. The objective of this research was to review the methods for the design, analysis and reporting of nonrandomized intervention studies for child obesity prevention and to assess potential for bias. METHODS We conducted a review of nonrandomized intervention studies, including population health interventions, quasi-experimental studies and natural experiments, published from 2013 to 2017 that were identified in a recent systematic review. Data on study design, intervention and control groups, outcome measures, and statistical analyses, were extracted. Risk of bias was evaluated using the Risk of Bias in Non-Randomized Studies of Interventions (ROBINS-I) tool. RESULTS All identified studies (n = 23) included a school or community-based intervention and had a concurrent control group. Participants were 3-18 years and sample sizes were 100 to > 1 million. Study designs were described inconsistently, and interventions ranged from 14 weeks to 5 years. Obesity was compared between control and intervention groups using logistic or linear regression, analysis of variance and mixed effects regression. Only 48% of studies accounted for clustering, and methods to control for confounding and repeated measures varied substantially. Overall risk of bias was moderate to serious for all studies. CONCLUSION There are substantial opportunities to improve the methods for nonrandomized intervention studies and reduce bias. Future studies should use advanced statistical and causal epidemiology methods, including better control for confounding and clustering, to generate higher quality evidence and certainty regarding which obesity prevention interventions are effective.

Abstract
BACKGROUND Low levels of physical activity, sedentary behaviour and mental health problems are issues that have received considerable attention in the last decade. The aim of this systematic review and meta-analysis was to investigate effects of interventions targeting school-related physical activity or sedentary behaviour on mental health in children and adolescents and to identify the features of effective interventions. METHODS Scientific articles published between January 2009 and October 2019 fulfilling the following criteria were included: general populations of children and adolescents between age 4 and 19, all types of school-related efforts to promote physical activity or reduce sedentary behaviour. Study selection, data extraction and quality assessment were done by at least two authors independently of each other. Data were analysed with a random effects meta-analysis and by narrative moderator analyses. RESULTS The literature search resulted in 10265 unique articles. Thirty-one articles, describing 30 interventions, were finally included. Eleven relevant outcomes were identified: health-related quality of life, well-being, self-esteem and self-worth, resilience, positive effect, positive mental health, anxiety, depression, emotional problems, negative effect and internalising mental health problems. There was a significant beneficial effect of school-related physical activity interventions on resilience (Hedges' g = 0.748, 95% CI = 0.326; 1.170, p = 0.001), positive mental health (Hedges' g = 0.405, 95% CI = 0.208; 0.603, p = < 0.001), well-being (Hedges' g = 0.877, 95% CI = 0.356; 1.398, p = < 0.001) and anxiety (Hedges' g = 0.347, 95% CI = 0.072; 0.623, p = 0.013). Heterogeneity was moderate to high (I2 = 59-98%) between studies for all outcomes except positive effect, where heterogeneity was low (I2 = 2%). The narrative moderator analyses of outcomes based on 10 or more studies showed that age of the children moderated the effect of the intervention on internalising mental health problems. Interventions in younger children showed a significantly negative or no effect on internalising mental health problems while those in older children showed a significant positive or no effect. Moreover, studies with a high implementation reach showed a significant negative or no effect while those with a low level of implementation showed no or a positive effect. No signs of effect moderation were found for self-esteem, well-being or positive mental health. Risk of publication bias was evident for several outcomes, but adjustment did not change the results. CONCLUSIONS School-related physical activity interventions may reduce anxiety, increase resilience, improve well-being and increase positive mental health in children and adolescents. Considering the positive effects of physical activity on health in general, these findings may reinforce school-based initiatives to increase physical activity. However, the studies show considerable heterogeneity. The results should therefore be interpreted with caution. Future studies should report on implementation factors and more clearly describe the activities of the control group and whether the activity is added to or replacing ordinary physical education lessons in order to aid interpretation of results.

Effects of the Healthy Children, Healthy Families, Healthy Communities Program for Obesity Prevention among Vulnerable Children: A Cluster-Randomized Controlled Trial. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17082895. [PMID: 32331366 PMCID: PMC7215792 DOI: 10.3390/ijerph17082895] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/12/2020] [Revised: 04/15/2020] [Accepted: 04/20/2020] [Indexed: 11/24/2022]
Abstract
Background: We aimed to examine whether the Healthy Children, Healthy Families, and Healthy Communities Program, consisting of multi-level strategies for obesity prevention tailoring the context of socioeconomically vulnerable children based on an ecological perspective, would be effective on improving their healthy lifestyle behaviors and obesity status. Methods: Participants were 104 children (and 59 parents) enrolled in public welfare systems in Seoul, South Korea. Based on a cluster-randomized controlled trial (no. ISRCTN11347525), eight centers were randomly assigned to intervention (four centers, 49 children, 27 parents) versus control groups (four centers, 55 children, 32 parents). Multi-level interventions of child-, parent-, and center-level strategies were conducted for 12 weeks. Children’s healthy lifestyle behaviors and obesity status were assessed as daily recommended levels and body mass index ≥85th percentile, respectively. Parents’ parenting behaviors were measured by the Family Nutrition and Physical Activity scale. Results: Compared to the control group, the intervention group showed significant improvements in total composite scores of healthy-lifestyle behaviors—including 60-min of moderate physical activity—but not in obesity status among children. Moreover, the intervention group showed significant improvements in parenting behaviors among parents. Conclusion: The multi-level strategies for obesity prevention based on an ecological perspective may be effective for promoting healthy lifestyles among socioeconomically vulnerable children.

Abstract
Background The ‘Eat Right, Be Positive About Your Body and Live Actively’ (EPaL) intervention programme was developed to prevent overweight and disordered eating in Malaysian adolescents. This study aimed to evaluate the effectiveness of the EPaL programme on knowledge, attitudes and practices on healthy lifestyle and body composition (body mass index z-score [zBMI], waist circumference [WC] and body fat percentage [BF%]) among adolescents. Methods All measures were taken at three time points: before intervention (Pre), after intervention (Post I) and 3 months after intervention (Post II). The intervention group (IG) participated in the EPaL programme for 16 weeks, whereas the comparison group (CG) received no intervention. Seventy-six adolescents (IG: n = 34; CG: n = 42) aged 13–14 years were included in the final analysis. Repeated measures analysis of covariance (ANCOVA) was used to assess the impact of the EPaL intervention programme on the measures between groups (IG and CG) at Post I and Post II. Results The IG reported significantly higher knowledge scores at both Post I (adjusted mean difference = 3.34; 95% confidence interval [CI] = 0.99, 5.69; p = 0.006) and Post II (adjusted mean difference = 2.82; 95% CI = 0.86, 4.78; p = 0.005) compared with the CG. No significant differences between the IG and CG were found at either Post I or Post II in attitudes, practices, zBMI, WC and BF%. The proportion of participants who were overweight or obese was consistent from Pre to Post II in the IG (35.3%) and increased from 26.2% at Pre to 28.5% at Post II in the CG, but the difference was not statistically significant. The proportion of participants who had abdominal obesity in the IG decreased from 17.6% at Pre to 14.7% at Post II and increased from 16.7% at Pre to 21.4% at Post II in the CG, but the differences were not statistically significant. Conclusion Despite no significant reduction of body composition, this programme shows the positive effect on the adolescents’ knowledge regarding healthy lifestyle. This study contributes to the evidence on the effectiveness of school-based health interventions in Malaysian adolescents. Trial registration UMIN Clinical Trial Registration UMIN000024349.

Abstract
Evidence associates scholastic performance to quality of eating habits. However, there is limited information on this topic in Turkey, an emerging economy with notable disparities. Our work aimed to evaluate the effect of eating habits quality of high-school students in Turkey, on the Scholastic Aptitude Standardized Examination (TEOG) scores. The study was conducted in 29 different cities in Turkey during the academic year 2016–2017, involving students of ages 14–17 years (up to senior-high school). A dietary habits survey developed and validated for this population was distributed over the internet in February 2017. Apart from students’ TEOG scores, Family Affluence Score (FAS) was used to categorize the students into low, medium, and high financial standing. Eating Habits Score (EHS) was calculated by using a validated scoring system. A working sample of 298 participants was used. Based on our results, we observed that there is a significant positive correlation between EHS, FAS and success rate of students as assessed by TEOG scores. Further research on this subject should be conducted in combination with intervention studies to reveal potential strategies and policies that would enhance positive behavior change as it relates to nutritional habits, aiming at improved scholastic performance and overall health throughout lifespan.

Abstract
ABSTRACT Objective To determine the sustainability of food quality in an obesity-prevention strategy for adolescent girls. Methods The study is a randomized controlled trial with 253 girls (Mean=15.61, 95% Confidence Interval 15.51-15.72) enrolled in 10 vocational schools in São Paulo. The diet intake was determined using a “Food Frequency Questionnaire” and analyzed according to the Brazilian Healthy Eating Index-Revised adequacy, moderation, and overall scores. The adolescents’ dietary intake was compared to the baseline 6 months and 12 months post-intervention. Descriptive statistics and analyses of covariance were used, considering a 5% significance level. Results Significant increases were found on the components total fruits (F=6.98, p<0.01), total vegetables (F=5.76, p=0.02), beans (F=5.96, p=0.02), and whole cereals (F=12.35, p<0.001). However, there was also a significant decrease on the scores for milk and dairy (F=6.48, p=0.02), and oils (F=5.98, p=0.02). At 12-month post intervention, improvement on the overall score was found (F=3.89, p=0.05), but there was a decrease on the component whole cereals (F=11.85, p<0.001), as well as in milk and dairies (F=6.38, p=0.02). Despite no significant effect for the SoFAAS component, a moderate effect size was revealed (d=0.56). Conclusion There were significant effects on some diet quality components and for the overall scores at 6-month and 12-month post intervention. Therefore, sustainable dietary changes should be the focus of obesity prevention programs for adolescents. Socio-economic influences on diet behaviors would also need to be acknowledged.

Abstract
AIM This study aimed at assessing the effect of solution-focused interviews for the promotion of health locus of control and self-efficacy on adolescents' healthy lifestyles. METHOD The present study, which was designed as a quasi-experimental study, included pretest and post-test control groups and was conducted in the period between 5 February 2017 and 30 April 2017. The intervention group comprised 28 (n = 28) adolescents from a school, and the control group comprised 30 (n = 30) adolescents from another school. Solution-focused interviews, which included educational information regarding leading a healthy lifestyle as well as cognitive-behavioural interview, were conducted with the adolescents of the intervention group, 1 day per week (nine sessions in total). RESULTS In comparison to the control group, adolescents in the intervention group exhibited differences in all the sub-dimensions health promotion scale (p < 0.001). CONCLUSIONS These results established the applicability and effectiveness of the programme, such that the health promotion programme could be included in the literature. Moreover, it is anticipated that this programme would be applied in school settings in the future.

Abstract
Adolescent obesity is one of the most important public health problems today. Identifying factors that affect obesity in adolescents and developing programs to prevent obesity are very important. This research aims to test Turkish psychometric properties of the scales to predict adolescent obesity (Healthy Lifestyle Choices Scale, Perceived Healthy Lifestyle Difficulty Scale, Activity Knowledge Scale, Nutrition Knowledge Scale, Healthy Lifestyle Attitude Scale, Healthy Lifestyle Belief Scale). The psychometric properties of the Scales were tested test-re-test reliability, the Cronbach's alpha coefficient, the item-total correlation, and the Confirmatory Factor Analysis. The relationship between the Scales was measured using the Spearman's correlation analysis. The level of internal consistency of the scales to predict adolescent obesity was found good. The goodness of fit values of the Belief Scale were measured as significantly high (χ2 = 177.24, df = 0.99, χ2/df = 1.79 (p < .001), Comparative Fit Index = 0.91, Goodness of Fit Index = 0.91, Normed Fit Index = 0.92, Incremental Fit Index = 0.92, Root Mean Square Residual = 0.05, Root Mean Square Error of Approximation Residual = 0.05). The psychometric analyses of the Scales were found to be very similar to the results of the original scales. There was a positive correlation between the Choice, Attitude, Belief, Nutrition and Activity Knowledge Scale, and a negative correlation with the Perceived Difficulty scale. The scales which measure adolescent obesity were accepted as valid and reliable measuring tools. This study will be an important resource for researchers working on the adolescent health and obesity.

Abstract
Sleeping difficulties are increasingly prevalent among adolescents worldwide and have negative consequences for adolescent health and education. The aim of this study was to describe the reasons for sleeping difficulties as perceived by adolescents. Sleeping difficulties include insufficient sleep, trouble falling asleep, waking up at night or sleep that does not leave an individual rested. Data were collected in 2015 using an open‐ended question. The sample consisted of n = 475 adolescents from a city in Sweden, aged 15–16 years, with self‐assessed sleeping difficulties. The results described the reasons for the adolescents’ sleeping difficulties, at a general, thematic level, as an imbalance between requirements and preconditions, distributed to stress, technology use, poor sleep habits, existential thoughts, needs and suffering. To find a balance in their daily lives, adolescents may need support from parents, school nurses and school health services to deal with their sleeping difficulties.

Abstract
Pediatric obesity is a major public health concern in low- and middle-income countries, such as Brazil. There is an urgent need for preventive programs for adolescents and, the assessment of their sustained impact. This paper reports the longer-term (6-month post intervention) effects of the "H3G-Brazil" obesity prevention program on weight status and weight-related behaviors. A cluster randomized controlled trial starting with 10 public schools in the city of São Paulo, Brazil involved 253 adolescent girls [mean (se) age = 15.6 (0.87) years]. Body mass index (BMI), waist circumference (WC), dietary intake, physical activity (PA) and sedentary behaviors (SB) were assessed at baseline, immediate post-intervention and 6-month post-intervention (follow-up). ANCOVA was performed using intention to treat principles. There was no effect on BMI, the primary outcome. Although, meaningful increases occurred in waist circumference for both groups, the intervention group presented a lower increase (F = 3.31, p = 0.04). This effect size, however, was lower than the criterion for small (d = 0.102). Unfortunately, significant results favored the control group for time spent on TV/weekdays (F = 5.13, p = 0.01), TV/weekends (F = 5.46, p = 0.01) and sedentary behaviors/weekdays (F = 5.32, p = 0.04). No other significant results were found. This obesity prevention intervention among Brazilian adolescent girls did not have the desire effect on BMI. The significantly lower increase in waist circumference in the intervention groups is inconsistent with the adverse changes detected in sedentary time.

Abstract
In view of the prevalence, health consequences, and costs of childhood obesity, there has been substantial interest in identifying effective interventions to prevent excess weight gain in young people. In this systematic review, we expand on previous reviews of obesity prevention interventions by including recent studies (until May 23, 2017) from all parts of the world. We searched MEDLINE, Embase, CINAHL Plus, Web of Science, CAB Abstracts, and PAIS Index and included randomised controlled trials, quasi-experimental studies, or natural experiments with: (1) a control group; (2) minimum follow-up of 12 months for community-based and home-based interventions or 6 months for school-based and preschool-based interventions; and (3) a primary outcome of BMI, BMI Z score, BMI percentile, body fat percentage, skinfold thickness, waist circumference, or prevalence of overweight or obesity. School-based interventions with combined diet and physical activity components and a home element (n=41) had greatest effectiveness; evidence in support of the effect of preschool-based (n=6), community-based (n=7), and home-based (n=2) interventions was limited by a paucity of studies and heterogeneity in study design. The effectiveness of school-based interventions that combined diet and physical activity components suggests that they hold promise for childhood obesity prevention worldwide. More research with rigorous evaluation and consistent reporting is needed in non-school settings and in combinations of settings.
