Effectiveness of nutrition interventions in Australian secondary schools: A systematic review.

ISSUE ADDRESSED: Dietary intake of Australian adolescents is suboptimal. Schools are an ideal setting for health promotion initiatives to develop healthy lifestyle behaviours among adolescents. However, we do not know which nutrition-focused, school-based interventions are effective at improving health outcomes in adolescents in Australia. Therefore, the aim was to evaluate the effect of nutrition interventions on health outcomes in Australian secondary school students. METHODS: MEDLINE, EMBASE, CINAHL, ERIC and Informit were systematically searched on 4th November 2022. Studies in any language evaluating nutrition interventions implemented in Australian secondary schools were included. Studies evaluating interventions conducted in primary schools or outside the school setting were excluded, as were any grey literature, systematic reviews and meta-analyses. Screening and data extraction were performed in duplicate. Quality was assessed using the Mixed Methods Appraisal Tool. RESULTS: Thirteen studies (n = 27 224) reporting on nutrition interventions implemented in Australian secondary schools were included. Studies were conducted in five different states and a capital territory within Australia and were mostly randomised controlled trials. Most studies reported a significant improvement on nutrition-related health outcome measures (dietary behaviour n = 6, nutritional knowledge and attitudes n = 4 and anthropometric n = 1). CONCLUSIONS: This review found limited studies reporting on nutrition interventions in Australian secondary schools. However, most were shown to be effective in improving nutrition-related health outcomes. SO WHAT?: Since there were limited studies in peer-reviewed journals, more research in this area is needed to confirm the effectiveness of nutrition interventions in Australian secondary schools and to assess long-term effects on student's health outcomes.

Supporting Health Care Staff With Family Meals During the COVID-19 Pandemic.

Family meals provide a unique opportunity for families to eat well and engage positively with each other. In response to the challenges presented by the COVID-19 (coronavirus disease 2019) pandemic, a new initiative to support health care staff to share healthy meals with their families was developed. At a hospital in Queensland, Australia, dietetic staff collaborated with the on-site food service retailer to develop and offer a range of hot meals that staff could take home for their families at the end of their day. The meals were nutritious, reasonably priced, and designed to feed a family of four. The dietetic staff worked with the hospital marketing department and staff health and wellness program to promote the initiative. Over the 3 months that it has been running, nearly 300 meals have been purchased. Anecdotal comments from the food service retailer highlighted that the initiative was a good thing to do for staff to maintain a positive reputation of the business. The staff evening meal initiative is a healthy, affordable, educational, and socially engaging alternative to takeaway meals and food delivery by app, and it is mutually beneficial for health care staff and the on-site food retailer. The initiative also offers a unique opportunity for promoting nutrition and social engagement during stressful times.

Experiential Features of Culinary Nutrition Education That Drive Behavior Change: Frameworks for Research and Practice.

Evidence of the benefits of culinary nutrition education is growing in the literature. Culinary nutrition education programs are naturally experiential, social, skills-based, and effective in improving nutrition-related beliefs, knowledge, and behaviors. In this article, we explore a set of motivational experiences in culinary nutrition education that have been identified as "drivers" of behavior change. These drivers emerged from 20 years of implementation and evaluation of hands-on cooking programs across the life span in more than 30 states within the United States. From these drivers, we developed a framework to guide both new and existing programs that can be best designed to motivate behavior change. These frameworks add value to the work of culinary nutrition educators and will inform and support future culinary nutrition education programs. In future research, health educators implementing skills-based health promotion programs in diverse settings can test the application of this framework to determine its relevance in broader areas.

Body size and weight, and the nutrition and activity behaviours of sexual and gender minority youth: findings and implications from New Zealand.

OBJECTIVE: To describe the body size and weight, and the nutrition and activity behaviours of sexual and gender minority (SGM) students and compare them with those of exclusively opposite-sex-attracted cisgender students. Male and female SGM students were also compared. DESIGN: Data were from a nationally representative health survey. SETTING: Secondary schools in New Zealand, 2012. PARTICIPANTS: A total of 7769 students, 9 % were SGM individuals. RESULTS: Overall, weight-control behaviours, poor nutrition and inactivity were common and, in many cases, more so for SGM students. Specifically, male SGM students (adjusted OR; 95 % CI) were significantly more likely to have tried to lose weight (1·95; 1·47, 2·59), engage in unhealthy weight control (2·17; 1·48, 3·19), consume fast food/takeaways (2·89; 2·01, 4·15) and be physically inactive (2·54; 1·65, 3·92), and were less likely to participate in a school sports team (0·57; 0·44, 0·75), compared with other males. Female SGM students (adjusted OR; 95 % CI) were significantly more likely to engage in unhealthy weight control (1·58; 1·20, 2·08), be overweight or obese (1·24; 1·01, 1·53) and consume fast food/takeaways (2·19; 1·59, 3·03), and were less likely to participate in a school sports team (0·62; 0·50, 0·76), compared with other females. Generally, female SGM students were more negatively affected than comparable males, except they were less likely to consume fast food/takeaways frequently (adjusted OR; 95 % CI: 0·62; 0·40, 0·96). CONCLUSIONS: SGM students reported increased weight-control behaviours, poor nutrition and inactivity. Professionals, including public health nutritionists, must recognize and help to address the challenges facing sexual and gender minorities.

Trends in weight-related attitudes and behaviours among New Zealand adolescents, between 2007 and 2012.

AIM: To explore secular trends of adolescent weight control concerns and behaviours, between 2007 and 2012, and determine if these vary by body size. METHODS: Data were drawn from two nationally representative youth health surveys, Youth'07 and Youth'12. Multiple logistic regression models were used to determine differences in the prevalence of weight control behaviours and concerns between the two time points, controlling for socio-demographic variables. RESULTS: Between 2007 and 2012, both boys and girls were significantly more likely to report concerns about their weight, though the prevalence of trying to lose weight increased for boys, but not girls. Trends in weight control behaviours varied by body size for boys and girls. Perhaps the most striking findings were the increases in proportions of underweight girls and healthy weight boys who were trying to lose weight. CONCLUSIONS: The current study highlights the growing concerns that young people are experiencing in relation to weight control. Given the persistently high rates of adolescent obesity in New Zealand and globally, greater support for young people with regards to healthy eating and weight management is warranted.

Family meals among parents: Associations with nutritional, social and emotional wellbeing.

A growing body of research suggests that children and adolescents who share frequent meals with their families report better nutrition indicators, family relationships and mental health. Yet, little research has examined whether parents who share meals with their families report the same indicators of wellbeing. The current paper addresses this question using population-based survey data and a sample of parents in the United States (n = 889, mean age 31 years) that responded to the fourth wave of the Project EAT study in 2015-16. Multiple regression models were used to examine associations between frequency of family meals and indicators of nutritional, social and emotional wellbeing, controlling for demographic and household characteristics. Analyses also examined if associations were moderated by sex, as mothers tend to be more responsible for household and childcare tasks. Results suggested that parent report of frequent family meals was associated with higher levels of family functioning, greater self-esteem, and lower levels of depressive symptoms and stress (p-value for all <0.001). Frequency of family meals was also related to greater fruit and vegetable consumption (both p < 0.05), but was unrelated to other indicators of parent body size and nutritional wellbeing. Associations between frequency of family meals and parent wellbeing were similar for both mothers and fathers. Findings from the current study suggest that frequent family meals may contribute to the social and emotional wellbeing of parents. Future strategies to promote family meals should consider the potential impacts on the health and wellbeing of the whole family.

Energy drink consumption among New Zealand adolescents: Associations with mental health, health risk behaviours and body size.

AIM: With the increase in popularity of energy drinks come multiple concerns about the associated health indicators of young people. The current study aims to describe the frequency of consumption of energy drinks in a nationally representative sample of adolescents and to explore the relationship between energy drink consumption and health risk behaviours, body size and mental health. METHODS: Data were collected as part of Youth'12, a nationally representative survey of high school students in New Zealand (2012). In total, 8500 students answered a comprehensive questionnaire about their health and well-being, including multiple measures of mental well-being, and were weighed and measured for height. RESULTS: More than one-third (35%) of young people consumed energy drinks in the past week, and 12% consumed energy drinks four or more times in the past week. Energy drink consumption was significantly associated with greater depressive symptoms, greater emotional difficulties and lower general subjective well-being. Frequent energy drink consumption was also associated with binge drinking, smoking, engagement in unsafe sex, violent behaviours, risky motor vehicle use and disordered eating behaviours. There was no association between consumption of energy drinks and student body size. CONCLUSIONS: Consumption of energy drinks is associated with a range of health risk behaviours for young people. Strategies to limit consumption of energy drinks by young people are warranted.

Dietary behaviours and the mental well-being of New Zealand adolescents.

AIM: To examine the associations between diet and mental health indicators in adolescents. METHODS: Data were drawn from the Youth 2012 survey, a national survey of the health and well-being of adolescents in New Zealand (n = 8500). Multiple regression models were used to determine the associations between healthy and unhealthy eating and mental health indicators while adjusting for sex, age, ethnicity, small area deprivation and household poverty as covariates. RESULTS: Approximately 30% of young people in the lowest quartile for healthy eating reported significant depressive symptoms. Greater healthy eating was significantly associated with fewer depressive symptoms, better well-being and fewer emotional difficulties (all P < 0.001 after adjusting for covariates). Greater unhealthy eating was significantly associated with greater depressive symptoms, poorer well-being and greater emotional difficulties (all P < 0.001 after adjusting for covariates). CONCLUSIONS: Findings from this study contribute to a growing body of literature that indicate that eating behaviours are associated with mental health indicators among adolescents. Findings from the current study suggest that efforts to enhance healthy eating may also have a positive impact on mental health.

Home Gardening and the Health and Well-Being of Adolescents.

BACKGROUND: The current article explores the associations between home gardening and dietary behaviors, physical activity, mental health, and social relationships among secondary school students in New Zealand. METHOD: Data were drawn from a national youth health and well-being survey, conducted in 2012. In total, 8,500 randomly selected students from 91 randomly selected secondary schools completed the survey. RESULTS: Two thirds of students had a vegetable garden at home and one quarter of all students participated in home gardening. Students participating in gardening were most likely to be male, of a Pacific Island ethnicity, of younger age, and living in a rural area. Gardening was positively associated with healthy dietary habits among students, such as greater fruit and vegetable consumption. Gardening was also positively associated with physical activity and improved mental health and well-being. Students who participate in gardening report slightly lower levels of depressive symptoms and enhanced emotional well-being and experience higher family connection than students who do not participate in gardening. CONCLUSIONS: Gardening may make a difference for health and nutrition behaviors and may contribute to adolescents' health and well-being in a positive manner. Health promoters should be encouraged to include gardening in future interventions for young people.

School gardens and adolescent nutrition and BMI: Results from a national, multilevel study.

OBJECTIVE: The aim of the current study was to determine the impact of school gardens on student eating behaviors, physical activity and BMI in New Zealand secondary schools. The current study also aimed to determine if school gardens could buffer the association between household poverty and adolescent BMI. METHODS: Data were drawn from a national study of the health and wellbeing of New Zealand secondary school students (n=8500) conducted in 2012. Multilevel regression models were used to determine the association between school gardens (school-level) and student nutrition behaviors, physical activity and measured BMI (student-level). RESULTS: Approximately half of secondary schools had a fruit/vegetable garden for students to participate in. School gardens were associated with lower student BMI (p=0.01) and lower prevalence of overweight (p<0.01). CONCLUSIONS: School gardens appear to have a positive impact on student health. Future research may explore how school gardens are implemented to better understand their impact and to extend the benefits beyond the school community.

The association between socioeconomic deprivation and secondary school students' health: findings from a latent class analysis of a national adolescent health survey.

BACKGROUND: The aims of this study were to examine indicators of socioeconomic deprivation among secondary school students and to determine associations between household poverty, neighbourhood deprivation and health indicators. METHODS: Data were from a nationally representative sample of 8500 secondary school students in New Zealand who participated in a health survey in 2012. Latent class analyses were used to group students by household poverty based on nine indicators of household socioeconomic deprivation: no car; no phone; no computer; their parent/s worry about not having enough money for food; more than two people sharing a bedroom; no holidays with their families; moving home more than twice that year; garages or living rooms used as bedrooms; and, no parent at home with employment. Multilevel generalized linear models were used to estimate the cross-level interaction between household poverty and neighbourhood deprivation with depressive symptoms, cigarette smoking and overweight/ obesity. RESULTS: Three groups of students were identified: 80 % of students had low levels of household poverty across all indicators; 15 % experienced moderate poverty; and 5 % experienced high levels of poverty. Depressive symptoms and cigarette smoking were 2-3 times higher in the poverty groups compared to student's not experiencing poverty. There were also higher rates of overweight/ obesity among students in the poverty groups compared to students not experiencing poverty, but once covariates were accounted for the relationship was less clear. Of note, students experiencing poverty and living in affluent neighbourhoods reported higher levels of depressive symptoms and higher rates of cigarette smoking than students experiencing poverty and living in low socioeconomic neighbourhoods. This cross-level interaction was not seen for overweight/ obesity. CONCLUSIONS: Measures of household socioeconomic deprivation among young people should not be combined with neighbourhood measures of socioeconomic deprivation due to non-linear relationships with health and behaviour indicators. Policies are needed that address household poverty alongside efforts to reduce socioeconomic inequalities in neighbourhoods.

Lunch frequency among adolescents: associations with sociodemographic factors and school characteristics.

OBJECTIVE: To investigate: (i) how lunch frequency of adolescents varies between schools and between classes within schools; (ii) the associations between frequency of lunch and individual sociodemographic factors and school characteristics; and (iii) if any observed associations between lunch frequency and school characteristics vary by gender and age groups. DESIGN: Cross-sectional study in which students and school headmasters completed self-administered questionnaires. Associations were estimated by multilevel multivariate logistic regression. SETTING: The Danish arm of the Health Behaviour in School-Aged Children study 2010. SUBJECTS: Students (n 4922) aged 11, 13 and 15 years attending a random sample of seventy-three schools. RESULTS: The school-level and class-level variations in low lunch frequency were small (intraclass correlation coefficient <2·1 %). At the individual level, low lunch frequency was most common among students who were boys, 13- and 15-year-olds, from medium and low family social class, descendants of immigrants, living in a single-parent family and in a reconstructed family. School-level analyses suggested that having access to a canteen at school was associated with low lunch frequency (OR=1·47; 95% CI 1·14, 1·89). Likewise not having an adult present during lunch breaks was associated with low lunch frequency (OR=1·44; 95% CI 1·18, 1·75). Cross-level interactions suggested that these associations differed by age group. CONCLUSIONS: Lunch frequency among Danish students appears to be largely influenced by sociodemographic factors. Additionally, the presence of an adult during lunch breaks promotes frequent lunch consumption while availability of a canteen may discourage frequent lunch consumption. These findings vary between older and younger students.

The Association Between Supportive High School Environments and Depressive Symptoms and Suicidality Among Sexual Minority Students.

The purpose of this study was to determine if sexual minority students in supportive school environments experienced fewer depressive symptoms and lower rates of suicide ideation, plans and attempts ("suicidality") than sexual minority students in less supportive school environments. In 2007, a nationally representative sample (N = 9,056) of students from 96 high schools in New Zealand used Internet tablets to complete a health and well-being survey that included questions on sexual attractions, depressive symptoms, and suicidality. Students reported their experience of supportive environments at school and gay, lesbian, bisexual, and transgender (GLBT) bullying, and these items were aggregated to the school level. Teachers (n = 2,901) from participating schools completed questionnaires on aspects of school climate, which included how supportive their schools were toward sexual minority students. Multilevel models were used to estimate school effects on depressive symptoms and suicidality controlling for background characteristics of students. Sexual minority students were more likely to report higher levels of depressive symptoms and suicidality than their opposite-sex attracted peers (p < .001). Teacher reports of more supportive school environments for GLBT students were associated with fewer depressive symptoms among male sexual minority students (p = .006) but not for female sexual minority students (p = .09). Likewise in schools where students reported a more supportive school environment, male sexual minority students reported fewer depressive symptoms (p = .006) and less suicidality (p < .001) than in schools where students reported less favorable school climates. These results suggest that schools play an important role in providing safe and supportive environments for male sexual minority students.

Wearable cameras can reduce dietary under-reporting: doubly labelled water validation of a camera-assisted 24 h recall.

Preliminary research has suggested that wearable cameras may reduce under-reporting of energy intake (EI) in self-reported dietary assessment. The aim of the present study was to test the validity of a wearable camera-assisted 24 h dietary recall against the doubly labelled water (DLW) technique. Total energy expenditure (TEE) was assessed over 15 d using the DLW protocol among forty adults (n 20 males, age 35 (sd 17) years, BMI 27 (sd 4) kg/m2 and n 20 females, age 28 (sd 7) years, BMI 22 (sd 2) kg/m2). EI was assessed using three multiple-pass 24 h dietary recalls (MP24) on days 2-4, 8-10 and 13-15. On the days before each nutrition assessment, participants wore an automated wearable camera (SenseCam (SC)) in free-living conditions. The wearable camera images were viewed by the participants following the completion of the dietary recall, and their changes in self-reported intakes were recorded (MP24+SC). TEE and EI assessed by the MP24 and MP24+SC methods were compared. Among men, the MP24 and MP24+SC measures underestimated TEE by 17 and 9%, respectively (P< 0.001 and P= 0.02). Among women, these measures underestimated TEE by 13 and 7%, respectively (P< 0.001 and P= 0.004). The assistance of the wearable camera (MP24+SC) reduced the magnitude of under-reporting by 8% for men and 6% for women compared with the MP24 alone (P< 0.001 and P< 0.001). The increase in EI was predominantly from the addition of 265 unreported foods (often snacks) as revealed by the participants during the image review. Wearable cameras enhance the accuracy of self-report by providing passive and objective information regarding dietary intake. High-definition image sensors and increased imaging frequency may improve the accuracy further.

The use of a wearable camera to capture and categorise the environmental and social context of self-identified eating episodes.

Research investigating the influence of the environmental and social factors on eating behaviours in free-living settings is limited. This study investigates the utility of using wearable camera images to assess the context of eating episodes. Adult participants (N = 40) wore a SenseCam wearable camera for 4 days (including 1 familiarisation day) over a 15-day period in free-living conditions, and had their diet assessed using three image-assisted multiple-pass 24-hour dietary recalls. The images of participants' eating episodes were analysed and annotated according to their environmental and social contexts; including eating location, external environment (indoor/outdoor), physical position, social interaction, and viewing media screens. Data for 107 days were used, with a total of 742 eating episodes considered for annotation. Twenty nine per cent (214/742) of the episodes could not be categorised due to absent images (12%, n = 85), dark/blurry images (8%, n = 58), camera not worn (7%, n = 54) and for mixed reasons (2%, n = 17). Most eating episodes were at home (59%) and indoors (91%). Meals at food retailers were 24.8 minutes longer (95% CI: 13.4 to 36.2) and were higher in energy (mean difference = 1196 kJ 95% CI: 242, 2149) than at home. Most episodes were seated at tables (27%) or sofas (26%), but eating standing (19%) or at desks (18%) were common. Social interaction was evident for 45% of episodes and media screens were viewed during 55% of episodes. Meals at home watching television were 3.1 minutes longer (95% CI: -0.6 to 6.7) and higher in energy intake than when no screen was viewed (543 kJ 95% CI: -32 to 1120). The environmental and social context that surrounds eating and dietary behaviours can be assessed using wearable camera images.

Feasibility of a Hospital-Based Kitchen Garden.

AIM: To explore the chef's experience with a newly implemented indoor hospital-based kitchen garden designed to supplement herbs ordered for patient meals and improve staff engagement. BACKGROUND: Hospital-based therapeutic and kitchen gardens have emerged as effective health-promoting tools in hospital healthcare environments. They promote emotional, mental, and physical well-being for patients, visitors, and staff. However, formal evaluations are limited, and studies focusing on indoor hospital kitchen gardens are noticeably absent in the literature. METHODS: Qualitative evaluation of a hospital-based kitchen garden. Open-ended interviews were conducted approximately 6 months after garden implementation and explored key informants (n = 6) overall experience, engagement with the garden, perceived benefits, and opportunities for improvement. Interview data was analyzed using a thematic approach. RESULTS: The implementation of the kitchen gardens was met with overall acceptance among staff. However, the project's feasibility faced challenges related to local food service leadership, communication, and certain aspects of the garden setup. Despite these obstacles, the gardens contributed positively to the quality of meals by including fresh herbs and fostering greater staff engagement. CONCLUSIONS: The chefs viewed the concept of the hospital-based kitchen garden favorably, noting that it closely aligned with their mission of providing nutritious meals to patients. However, consideration of the broader issues facing hospital food services may be required to seamlessly integrate this task into the kitchen staff's daily routine. Further research is warranted to investigate the effective implementation and feasibility of indoor kitchen gardens in hospitals and their impact on patient menus, food service staff, and the workforce.

Quantifying the locality of the food supply in a large healthcare organisation.

AIM: Shocks to the food system (such as extreme weather events, wars, and pandemics) are felt by institutional food systems. For hospitals, these shocks affect the quantity, quality, and variety of foods that can be offered to patients. One strategy to buffer the hospital food supply from external threats is to prioritise ingredients produced locally. Thus, the aim of the current research is to describe the country of origin of all foods purchased by a large, metropolitan healthcare organisation and to identify opportunities for improving the locality of the food supply. METHODS: This study was of a cross-sectional, observational design. The country of origin for all foods procured over a 1-year period by a large, urban healthcare organisation was determined by proportion of food budget spend. State of origin was identified for fresh fruit, vegetables, and meat. The organisation was in Queensland, Australia and utilised a cook-fresh, room-service foodservice model. Descriptive analysis was used to to determine the number of items and the proportion of budget spend on all foods produced in Australia, and by food category. Similar descriptive statistics were generated to determine the proportion of the budget spend on fresh fruits, vegetables and meats produced in Queensland. RESULTS: Over the 1-year period, 659 individual food items were purchased by the hospital foodservice, and 502 food items were included in the anlaysis. In total, 53% of the food budget was spent on Australian foods (100% Australian ingredients) and almost all fruit (73%) and vegetables (91%) were Australian grown. Procuring fresh fruit (28%), vegetables (35%), and meat (46%) from within the state was less common, and this may reflect the primary states of production across Australia, and seasonal variability of the food supply. CONCLUSIONS: Findings offer priority areas for improving the locality of the food supply. Future research to determine if procuring more foods locally has benefits to consistency of the food supply is warranted.

Dietary intake and quality among adults with cystic fibrosis: A systematic review.

AIMS: This systematic review aims to describe the dietary quality, dietary intake and related behaviours of adults diagnosed with cystic fibrosis. METHODS: A comprehensive literature search was conducted in four databases (Medline, CINAHL, EMBASE, CENTRAL); studies were included if they addressed dietary intake, diet quality or eating behaviours among adults (≥15 years) living with cystic fibrosis and were published from January 2000 to November 2022. The Mixed Methods Appraisal Tool was used to assess the risk of bias and quality of included studies. Findings were synthesised narratively. RESULTS: Nineteen observational studies (n = 2236) were included and considered high to moderate quality. Most (13/19) studies reported that individuals with cystic fibrosis were consuming high-energy diets; where studies reported energy intake as a proportion of requirements met, energy intake was high, even when using individualised or cystic fibrosis-specific referents. In addition, fat intakes as a proportion of energy appeared high (29%-39% of total energy), particularly as current guidelines recommend macronutrient profile similar to the general population (<30% of total energy). There was considerable variation in the reporting of fatty acid profiles and other nutrients. Five studies reported on concerns regarding diet and eating in this population. CONCLUSION: Findings from the current review suggest dietary intakes of adults with cystic fibrosis appear to be less than optimal and concerns about diet, weight and food may be emerging in this population. Future research utilising consistent measures of dietary assessment and reporting, reporting of medical therapies, and exploring potential concerns about diet and eating is warranted.

Prevalence of severe obesity among New Zealand adolescents and associations with health risk behaviors and emotional well-being.

OBJECTIVE: To describe the prevalence of severe obesity among New Zealand young people attending secondary school and the associations of severe obesity with health risk behaviors and emotional well-being. STUDY DESIGN: A random sample of 9107 secondary school students in New Zealand participated in a 2007 health survey. Participants had their height and weight measured and answered an anonymous survey on multiple aspects of their health and well-being. RESULTS: Overall, 2.5% of students met the International Obesity Task Force definition of severe obesity. Students with severe obesity had more weight-related concerns, were more likely to have used unhealthy weight control strategies, and were more likely to experience bullying compared with healthy weight students. For example, students with severe obesity were 1.7 times more likely to have been bullied at school (95% CI 1.2-2.7) and 1.9 times more likely to vomit for weight loss (95% CI 1.1-3.3) than were healthy weight students. Indicators of emotional well-being and most health risk behaviors were similar among young people with severe obesity and a healthy weight. CONCLUSIONS: Clinicians who work with young people with severe obesity should prioritize discussing issues of bullying and healthy weight control strategies with families and their children.

Family support and weight-loss strategies among adolescents reporting sustained weight loss.

OBJECTIVE: The current research aims to describe the weight-control strategies and family support for young people reporting sustained weight loss in a large, population-based sample. DESIGN: Data were collected as part of Youth'07, a nationally representative survey of the health and well-being of New Zealand youth. SETTING: New Zealand secondary schools, 2007. SUBJECTS: Secondary-school students (n 9107). RESULTS: Among young people who attempted weight loss in the previous year, 51% reported long-term weight loss (lost weight and maintained weight loss for 6 months). Students reporting long-term weight loss were more likely to be male, but did not differ by age, ethnicity, socio-economic deprivation or measured weight status from students who reported temporary/recent weight loss or no weight loss. Students with long-term weight loss also reported healthier weight-control strategies (e.g., exercising, eating fewer fatty foods, eating fewer sweets), high parental support for healthy eating/activity and were less likely to report being teased about their weight by their family and having junk food available at home than students with temporary/recent weight loss or no weight loss. CONCLUSIONS: Approximately 50% of young people attempting weight loss reported sustained weight loss. Young people who reported sustained weight loss appeared to have more family support than those who did not achieve this, suggesting the importance for weight-control services and interventions in adolescents of actively engaging the family.
