ISSUES ADDRESSED: People with severe mental illness have adverse health outcomes compared to the general population. Lifestyle interventions are effective in improving health outcomes in this population. Current cultural processes in mental health services do not generally incorporate physical health care practices. Innovative education is required to improve knowledge and confidence of staff in the delivery of preventative health measures. METHODS: The Keeping our Staff in Mind (KoSiM) program delivered a brief lifestyle intervention to mental health staff. A qualitative analysis following the Standards for Reporting Qualitative Research was undertaken. Semi-structured interviews designed to elicit information about the acceptability of the program and the impact of the intervention on participants' personal and professional lives. The interviews were analysed using thematic analysis, with coding independently developed and reviewed by three authors. RESULTS: Of the 103 eligible participants, 75 were interviewed. Responses revealed four main themes: (i) positive changes in clinician's approach to physical health care, (ii) improvements in attitudes to self-care and family wellbeing, (iii) positive changes in workplace culture associated with physical health care delivery and (iv) high levels of acceptability of the program. CONCLUSION: The KoSiM model may be useful in other settings as a means of changing the culture of mental health services to better integrate physical health care as a core part of mental health service provision. SO WHAT?: A novel approach using staff focussed lifestyle interventions model may cut through the resistance that is encountered when implementing proven methods of clinical intervention where cultural barriers exist.

There is a need for a detailed understanding of effective dietary interventions for children with obesity. This systematic review examined the effectiveness of diets of varying energy content as a component of weight treatment in children and adolescents with obesity, severe obesity and obesity-related comorbidity. A systematic search of six databases, from 2000 to 2021, for intervention studies of targeted dietary treatment for obesity in children aged 2-18 years identified 125 studies. Dietary interventions were grouped according to diet type and energy target. Risk of bias was assessed using the Effective Public Healthcare Panacea Project assessment tool. Meta-analysis examined change in body mass index (BMI) at intervention end. A broad array of diet types were effective at reducing BMI in children with obesity. When dietary types were considered by energy target, a gradient effect was observed. Very-low energy diets were most effective with a - 4.40 kg/m

Background Obesity among children and adolescents continues to rise worldwide. Despite the efforts of the healthcare workforce, limited high-quality evidence has been put forward demonstrating effective childhood obesity interventions. The role of nurses as primary actors in childhood obesity prevention has also been underresearched given the size of the workforce and their growing involvement in chronic disease prevention. Aim To examine the effectiveness of nurse-led interventions to prevent childhood and adolescent overweight and obesity. Design A systematic review of randomised trials. Data sources Medline, CINAHL, EMBASE, Cochrane (CENTRAL), ProQuest Central and SCOPUS were searched from inception to March 2020. Review methods This review was informed by the Cochrane handbook for systematic reviews of interventions. Results Twenty-six publications representing 18 discrete studies were included (nine primary prevention and nine secondary prevention). Nurse-led interventions were conducted in diverse settings, were multifaceted, often involved parents and used education, counselling and motivational interviewing to target behaviour change in children and adolescents' diet and physical activity. Most studies did not determine that nurse-led interventions were more effective than their comparator(s) in preventing childhood and adolescent overweight and obesity. Conclusions Nurse-led interventions to prevent juvenile obesity are feasible but have not yet determined effectiveness. With adequate training, nurses could make better use of existing clinical and situational opportunities to assist in the effort to prevent childhood obesity.

Aim To identify multi-disciplinary paediatric weight management services currently available in Australia and determine gaps in service provision for children and adolescents with obesity. Methods Surveys were distributed to 17 identified Australian multi-disciplinary paediatric weight management services. A representative from each service was asked to complete an online survey regarding service and patient characteristics, assessment and management practices, and professional development approaches. Results Representatives from 16 multi-disciplinary paediatric weight management services completed the survey. Fourteen services were based in major metropolitan cities and two in regional areas. Fourteen services provided care to pre-school aged children (0-4 years old), 15 to primary school aged children (5-12 years old) and 13 to high school aged children (13-18 years old). The number of patients seen per year per service ranged from 20 to 250 and duration of waiting lists ranged from 2 months to more than 12 months. Conclusions The current availability and accessibility of multi-disciplinary paediatric weight management services is inadequate to service Australian children and adolescents with obesity, particularly those with severe obesity and those in rural and remote communities. To better address the issue of paediatric obesity, establishment of additional multi-disciplinary services, training for health-care professionals and monitoring of the provision of evidence-based care is urgently needed.

The use of infant formula is widespread internationally. In Australia, 55% of infants receive formula before 6 months of age, with higher rates among disadvantaged communities. Infant formula use can contribute to childhood overweight and obesity, through formula composition and feeding behaviours, such as adding cereal to bottles and parental feeding style. While information abounds to promote and support breastfeeding, formula-feeding parents report a paucity of advice and support; many rely on formula packaging for information. This study systematically searched and reviewed online resources for infant formula and bottle feeding from Australian governments, health services, hospitals, and not-for-profit parenting organisations. A comprehensive search strategy located 74 current resources, mostly for parents. Researchers evaluated the resources against best practice criteria derived from Australian government and UNICEF guidelines on six topics. They assessed how comprehensively the resources addressed each topic and whether the resources provided all the information necessary for parents to understand each topic. The mean 'comprehensiveness' rating for topics across all resources was 54.36%. However, some topics were addressed more fully than others. Information on 'discussing infant formula with health workers' and on 'preparing infant formula' was more frequently accurate and comprehensive. However, there was much less comprehensive information on 'using infant formula', including amounts of formula to feed, use of bottle teats, appropriate bottle-feeding practice and responsiveness to infant satiety cues. Over half the resources were written at an acceptable reading level.

The life expectancy gap experienced by people living with severe mental illness is primarily a result of cardiometabolic disease that is often exacerbated by side effects of antipsychotic medication. Commencement of atypical antipsychotic medication is commonly associated with weight gain. The Keeping the Body in Mind programme has demonstrated that early intervention with lifestyle activities can attenuate this weight gain and potentially improve long-term health outcomes. The aim of this study was to explore the experiences of young people who participated in the Keeping the Body in Mind programme, a targeted lifestyle intervention programme. A qualitative approach was used employing a semi-structured interview format. The interview schedule included questions related to four topics: aspects of the programmes that were useful, attributes of staff members that influenced the programme, changes in attitudes towards their own physical health, and suggestions for programme improvements. Interviews were recorded with duration ranging from 40 to 65 min. Thematic analysis was used to detect and assemble codes. These were then synthesized and classified into themes. Eleven participants were interviewed (seven males), aged between 18 and 25 years. Thematic analysis revealed four main themes: the role of physical health in mental health recovery; the importance of staff interactions; the value of peer interaction; and graduation to a sustainable healthy lifestyle. Study participants reported that they valued the programme for both their physical health and mental health recovery.

Background A range of postnatal and maternal factors influences childhood obesity, but their relative importance remains unclear. This study aimed to assess the relative impact of postnatal rapid growth and maternal factors on early childhood growth trajectories. Subjects Secondary longitudinal analysis of pooled data from the Melbourne Infant Feeding Activity and Nutrition Trial (InFANT) Program and the InFANT Extend Program (n = 977) was performed. Children's height and weight were collected at birth, 3, 9, 18, and 36/42 months. Body mass index-for-age and height-for-age z-scores (BAZ, HAZ) were computed using WHO growth standards. Mixed-effect polynomial regression models were fitted to examine BAZ and HAZ trajectories and their determinants. Results Rapid growth from birth to 3 months, maternal country of birth, and pre-pregnancy BMI were each independently associated with BAZ from 3 to 42 months. Children with rapid growth, those whose mothers were Australian-born, and those whose mothers were overweight/obese pre-pregnancy had higher BAZ from 3 to 42 months. Children with rapid growth had an increase in HAZ growth, but their average HAZ from 3 to 42 months was smaller than children without rapid growth. Children of tall mothers (above average height) had higher HAZ than those of short mothers (below average height). Average HAZ from 3 to 42 months did not differ by maternal country of birth. Conclusion Children who experienced rapid growth from birth to 3 months, whose mothers were Australian-born or whose mothers were overweight/obese pre-pregnancy demonstrated less favourable growth trajectories across early childhood, potentially predispose them for development of future obesity.

Early intervention is critical for addressing the challenge of childhood obesity. Yet many preventive interventions do not target infants most at risk of future overweight or obesity. This systematic review examines interventions delivered before 2 years that aim to ameliorate excess weight gain among infants at high risk of overweight or obesity, due to sociodemographic characteristics, parental weight or health status, infant feeding or health behaviours. We searched six databases for interventions: (a) delivered before age two, (b) specifically aimed at infants at high risk of childhood obesity and (c) that reported outcomes by weight status beyond 28 days. The search identified over 27,000 titles, and 49 papers from 38 studies met inclusion criteria: 10 antenatal interventions, 16 postnatal and 12 conducted both before and after birth. Nearly all targeted infant and/or maternal nutrition. Studies varied widely in design, obesity risk factors, outcomes and quality. Overall, nine interventions of varying quality reported some evidence of significantly improved child weight trajectory, although effects tended to diminish over time. Interventions that improved weight outcomes tended to engage parents for a longer period, and most offered health professional input and support. Two studies of limited quality reported significantly worse weight outcomes in the intervention group.

Aim Approximately 20% of Australian pre-school children are overweight. Primary care providers have a crucial role in identifying children at risk of unhealthy weight gain and to offer advice and suggestions to parents. The Healthy 4 Life pilot study aimed to develop and test the feasibility of a practice nurse (PN)-led brief intervention into a healthy kid's check in general practice. Methods A PN intervention was developed based on a needs assessment and existing literature. A workshop was conducted, and resources were provided to enable four PNs to deliver a brief obesity prevention intervention to parents. Nurses then incorporated the Healthy 4 Life components into the healthy kid's checks they conducted on the next 10 children. Medical records were reviewed and nurses interviewed to establish the feasibility of the intervention. Results All of the nurses incorporated some Healthy 4 Life components into their healthy kid's checks. Body mass index was calculated and plotted for all children, and advice around healthy eating was offered in 60% of consultations; however, advice about limiting screen time provided in only 2% of consultations. Nurses reported that the intervention fitted well with their current practice, although time constraints were a concern for some nurses and some parents. Conclusion The provision of a brief training workshop and resources can equip nurses in general practice to offer an obesity prevention intervention to parents of young children. Further research is required to examine the impact of such an intervention on parent and child behaviours and the sustainability of such practices for PNs.

Aim The aims of this paper are to describe the growth of urban Australian Aboriginal infants from birth to 24 months of age and to identify the proportion of these infants experiencing rapid weight gain (RWG) and overweight/obesity. Methods The Gudaga Study is a longitudinal birth cohort of 159 Australian Aboriginal children born on the urban fringe of Sydney. Birthweight and length were extracted from hospital data. Children with a birthweight >1500 grams were included in the analysis (n = 157). Weight, length and head circumference were measured at 2–3 weeks and then six-monthly until 24 months of age. Age- and gender-specific Z-scores were determined from the Centers for Disease Control (CDC) 2000 growth charts for weight, length, head circumference and body mass index (BMI). The proportion of children experiencing RWG (an increase in weight-for-age Z-scores ≥0.67 between birth and 12 months) was calculated. The association between RWG and ≥85th CDC percentile for BMI at 24 months was tested using Pearson's χ2. Results The mean weight of Gudaga infants was less than the CDC mean length-for-age at birth and 2–3 weeks of age but greater than CDC mean length-for-age and weight-for-age at 18 and 24 months of age. Overall, 42 infants (34.4%) experienced RWG, and 45 infants (36.9%) were overweight/obese at 24 months of age. A greater proportion of those who experienced RWG (61.9%) were overweight/obese at 24 months than those who did not experience RWG (23.8%). Conclusion Our study suggests a concerning proportion of urban Indigenous infants experience RWG and overweight/obesity in early childhood.

Aim Overweight and obesity affects approximately 20% of Australian pre-schoolers. The general practice nurse (PN) workforce has increased in recent years; however, little is known of PN capacity and potential to provide routine advice for the prevention of child obesity. This mixed methods pilot study aims to explore the current practices, attitudes, confidence and training needs of Australian PNs surrounding child obesity prevention in the general practice setting. Methods PNs from three Divisions of General Practice in New South Wales were invited to complete a questionnaire investigating PN roles, attitudes and practices in preventive care with a focus on child obesity. A total of 59 questionnaires were returned (response rate 22%). Semi-structured qualitative interviews were also conducted with a subsample of PNs (n = 10). Results Questionnaire respondent demographics were similar to that of national PN data. PNs described preventive work as enjoyable despite some perceived barriers including lack of confidence. Number of years working in general practice did not appear to strongly influence nurses' perceived barriers. Seventy per cent of PNs were interested in being more involved in conducting child health checks in practice, and 85% expressed an interest in taking part in child obesity prevention training. Conclusions Findings from this pilot study suggest that PNs are interested in prevention of child obesity despite barriers to practice and low confidence levels. More research is needed to determine the effect of training on PN confidence and behaviours in providing routine healthy life-style messages for the prevention of child obesity.

Aim: To determine the health-care charges associated with monitoring and managing, over 1 year, the cases of elevated insulin concentration, elevated alanine aminotransferase concentration and dyslipidaemia due to overweight or obesity among 15-19-year-old Australian males and females. Methods: Fasting blood samples (n = 500) were collected in 2004 from a representative population sample of adolescents (n = 496; mean age 15.3 years) attending schools in Sydney, Australia. Full service charges and Medicare expenditures for specialist medical and dietary consultations, pathology tests and radiological investigations, over 1 year, under efficient and inefficient health-care delivery models, including and excluding participants in the healthy body mass index (BMI) category. Results: Under an inefficient delivery model and including all participants with elevated risk factors, the Medicare expenditure was $A305.1 million per annum (M pa). Exclusion of participants in the healthy BMI category resulted in an annual Medicare expenditure of $A170.0M pa. Under an efficient delivery model and including all participants with elevated risk factors, the Medicare expenditure was $A295.5M pa. Exclusion of participants in the healthy BMI category reduced annual Medicare expenditure to $A164.8M pa. Medicare expenditure for 15-19-year-olds would increase by 48% if only cases among overweight and obese adolescents were treated and by 85% if all cases were identified and treated. Conclusions: Short-term management of the health consequences of overweight and obesity among adolescents will increase Medicare expenditure on this group by at least 48%. Failure to treat will delay, but compound, health-care expenditure. © 2009 Paediatrics and Child Health Division (Royal Australasian College of Physicians).

Aim: Relatively little is known about the results of liver tests among adolescents. The purpose of this study was to describe the distributions of liver tests, to identify the upper normal limits (UNLs) and to describe the correlations among liver tests. Methods: Overnight fasting blood samples were collected from a representative population sample of 500 Grade 10 students (15 years old) attending schools in Sydney, Australia. Weight, height and waist girth were measured. UNLs were calculated for each enzyme as the 95th percentiles of the healthy body mass index category, after excluding those with high blood pressure, elevated low-density lipoprotein cholesterol (≥3.4 mmol/L) or triglyceride concentration (≥2.25 mmol/L) (n = 246). The distributions of alanine aminotransferase (ALT), γ-glutamyltransferase (GGT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) were described, UNLs were identified and the correlations between enzyme concentrations were described. Results: The UNLs for ALT were 32 and 20 U/L; for GGT, 24 and 19 U/L; for AST, 33 and 26 U/L; and for ALP, 385 and 183 U/L, for boys and girls, respectively. ALT concentration was strongly correlated with GGT and AST (r = 0.5–0.6). Neither ALT nor GGT concentrations were correlated with ALP concentration, but AST concentration was moderately correlated with ALP concentration. Conclusions: These data are valuable in defining the distributions of liver tests, normal liver test ranges and relationships between liver tests among adolescents.

Aim: To examine the nature and availability of paediatric obesity services in tertiary care settings across the states/territories of Australia. Methods: Surveys were sent to all clinicians identified as offering obesity services to children and adolescents. Respondents were asked to identify other service providers in their area, who were also asked to complete the survey. Results: Sixteen clinicians responded to the survey, from 20 requests. The clinicians who responded identified nine services in three of the eight states/territories of Australia. Existing services are limited to children and adolescents with severe obesity, with an average of 12 new referrals per service each month and an average waiting time of 5 months for an appointment. Most services involve a multidisciplinary approach, although the mix of staff varies considerably and emphasises nutrition rather than physical activity approaches. Conclusions: Despite the public attention devoted to paediatric obesity, tertiary services in Australia are inadequate to meet the increasing incidence and prevalence of this complex condition. The development of tertiary services as part of service delivery arrangements for paediatric obesity and its associated morbidities must become a priority within the health system.

AIM: Active transport to and from school is frequently identified as an opportunity to increase energy expenditure among young people. The epidemiology of travel behaviours among Grade 6, 8 and 10 students in NSW is reported. METHODS: A representative population survey of students in NSW, Australia was conducted during February to May 2004 (n = 2750) and the prevalence of travelling to and from school by walking, car and public transport was determined for Grade 6, 8 and 10 students. RESULTS: Among Grade 6 students, approximately 30% travelled by car, 30% walked and 20% used public transport to travel to school (the travel habits of 20% could not be accurately characterised). Among secondary school students, approximately 50% used public transport, 15-20% travelled by car and 15-20% walked. Among those who walked or used public transport, the median times spent walking were 10-15 min and 5 min per trip, respectively. CONCLUSIONS: While there is little scope to increase the prevalence of active transport among secondary school students, there is potential to do so among primary school students. Primary school students who replace travelling to and from school by car with walking will experience an increase in activity energy expenditure of up to 10% and those who change to public transport will experience an increase in activity energy expenditure of up to 3%.

Objective: To determine secular trends in overweight/obesity among 7- to 15-year-olds for the periods 1985, 1997, and 2004. Research Method and Procedures: Data from representative surveys conducted in New South Wales, Australia, in 1985, 1997, and 2004 were analyzed. Height and weight were measured, and BMI categories were created using International Obesity Task Force definitions. Students were grouped as Grades 2 + 4 + 6 and 8 + 10. Results: The prevalences of overweight/obesity for 1985, 1997, and 2004 were 10.9%, 20.6%, and 25.7% among the younger boys and 10.6%, 19.5%, and 26.1% among the older boys. The average annual rate of increase for 1985 to 1997 was 0.81% and for 1997 to 2004 was 0.73% among the younger boys and was 0.74% and 0.94% for the two periods among the older boys. The prevalences of overweight/obesity in 1985, 1997, and 2004 were 14.0%, 22.0%, and 24.8% among the younger girls and 8.3%, 17.9%, and 19.8% among the older girls, respectively. The average annual rates of increase for the two periods were 0.8% and 0.4% among the younger girls and 0.80% and 0.27% among the older girls. Change in the prevalence of overweight/obesity and socioeconomic status were not associated. Discussion: Over the period 1985 to 1997, the prevalence of overweight and obesity increased significantly among the younger and older boys and the younger girls. The prevalence of overweight, but not obesity, increased among the older girls over this period. Over the period 1997 to 2004, the prevalence of overweight/obesity combined increased significantly among boys of both age groups but not among girls.

Aim: To describe the epidemiology of small screen recreation (SSR) that is: television, computer, video, and DVD use among school students aged 11–15 years in New South Wales, Australia. Methods: Cross-sectional representative population survey (n = 2750) of 45 primary and 48 secondary schools in rural and urban areas. Self-reported time spent in SSR was categorised according to national guidelines into less than 2 h per day (low users) or 2 or more hours per day (high users). Results: Of primary and secondary school students, 53% and 72%, respectively, were high users of SSR. Boys spent significantly more time in SSR and were more likely to be high users of SSR compared with girls. For primary students, rural boys had a higher prevalence of high SSR use than urban boys (odds ratio (OR) 1.9, 95% confidence interval (CI) 1.0–3.5), while overweight girls had a higher prevalence than healthy-weight girls (OR 1.8, 95% CI 1.2–2.8). For secondary students, rural boys had a lower prevalence of high SSR use than urban boys (OR 0.5, 95% CI 0.3–0.6), and girls from high SES backgrounds had a lower prevalence than girls from low socio-economic status backgrounds (OR 0.6, 95% CI 0.3–1.0). Conclusion: The majority of school students in New South Wales exceed the national guidelines for SSR. Reducing the time spent in SSR among young people is one potential approach to increasing energy expenditure and reducing adiposity or maintaining a healthy weight. First steps for intervention strategies among school-age children to reduce SSR could include teaching awareness skills and self-monitoring techniques.
