Nutrition and the Primary School Child

With a greater range of foodstuffs available today, it is necessary to educate children in choosing the correct foods to eat, and why they should eat them in preference to others. The concept of nutrition is related closely to the growth and well being of the child and subsequently should be an important part of a child\u27s primary school education

Public health service options for affordable and accessible noncommunicable disease and related chronic disease prevention and management

Globally, nations are confronted with the challenge of providing affordable health services to populations with increasing levels of noncommunicable and chronic disease. Paradoxically, many nations can both celebrate increases in life expectancy and bemoan parallel increases in chronic disease prevalence. Simply put, despite living longer, not all of that time is spent in good health. Combined with factors such as rising levels of obesity and related noncommunicable disease, the demand for health services is requiring nations to consider new models of affordable health care. Given the level of disease burden, all staff, not just doctors, need to be part of the solution and encouraged to innovate and deliver better and more affordable health care, particularly preventative primary health care services. This paper draws attention to a range of exemplars to encourage and stimulate readers to think beyond traditional models of primary health service delivery. Examples include nurse-led, allied health-led, and student-led clinics; student-assisted services; and community empowerment models. These are reported for the interest of policy makers and health service managers involved in preventative and primary health service redesign initiatives

Supporting public health priorities: recommendations for physical education and physical activity promotion in schools

Physical activity (PA) provides numerous physiological and psychosocial benefits. However, lifestyle changes, including reduced PA opportunities in multiple settings, have resulted in an escalation of overweight and obesity and related health problems. Poor physical and mental health, including metabolic and cardiovascular problems is seen in progressively younger ages, and the systematic decline in school PA has contributed to this trend. Of note, the crowded school curriculum with an intense focus on academic achievement, lack of school leadership support, funding and resources, plus poor quality teaching are barriers to PA promotion in schools. The school setting and physical educators in particular, must embrace their role in public health by adopting a comprehensive school PA program. We provide an overview of key issues and challenges in the area plus best bets and recommendations for physical education and PA promotion in the school system moving forward

Childhood obesity in Asia: the value of accurate body composition methodology

Childhood obesity, a significant global public health problem, affects an increasing number of low- and middle-income countries, including in Asia. The obesity epidemic has been fuelled by the rapid nutrition and physical activity transition with the availability of more energy-dense nutrient-poor foods and lifestyles of many children dominated by physical inactivity. During the growing years the pace and quality of grow this best quantified by a combination of anthropometric and body composition measures. However, where normative data are available, this has typically been collected on Caucasian children. To better define and characterise overweight and obesity in Asian children, and to monitor nutrition and physical activity interventions, there is a need to increase the use of standardized anthropometric and body composition methodologies. The current paper reports on initiatives facilitated by the International Atomic Energy Agency (IAEA) and outlines future research needs for the prevention and management of childhood obesity in Asia

The effects of pediatric obesity on dynamic joint malalignment during gait

Background: There is a greater prevalence of lower extremity malalignment in obese children during static posture; however, there has been less examination of dynamic joint function in this cohort. Therefore, the purpose of this study was to determine kinematic differences that exist between obese and non-obese children that would support previously reported static joint malalignment. Methods: Forty children were classified as obese (n=20) or non-obese (n=20). Lower extremity joint kinematics were collected during five walking trials at a self-selected pace. Peak joint displacement and amount of joint motion throughout the gait cycle (calculated as the integrated displacement curve) were analyzed for group differences. Findings: Non-obese children had greater peak knee and hip extension during gait; however, there were no group differences in the integrated sagittal displacement curve. Obese children had greater peak angular displacement and integrals of angular displacement for peak hip adduction, hip internal rotation, and foot abduction (toe-out) than non-obese children. Obese children also had greater peak knee external rotation than non-obese children. Interpretation: Non-obese children showed greater range of motion in the sagittal plane, particularly at the hip and knee. Frontal and transverse plane differences suggest that obese children function in a more genu valgum position than non-obese children. Staticmeasures of genu valgum have been previously associated with pediatric obesity; the findings indicate that there are also dynamic implications of said malalignment in obese children. Genu valgum presents increased risk of osteoarthritis for obese children and should be considered when prescribing weight bearing exercise to this cohort

Exercise physiologists: essential players in interdisciplinary teams for noncommunicable chronic disease management

Noncommunicable diseases (NCDs), such as obesity and type 2 diabetes mellitus, are a growing public health challenge in Australia, accounting for a significant and increasing cost to the health care system. Management of these chronic conditions is aided by interprofessional practice, but models of care require updating to incorporate the latest evidence-based practice. Increasing research evidence reports the benefits of physical activity and exercise on health status and the risk of inactivity to chronic disease development, yet physical activity advice is often the least comprehensive component of care. An essential but as yet underutilized player in NCD prevention and management is the “accredited exercise physiologist,” a specialist in the delivery of clinical exercise prescriptions for the prevention or management of chronic and complex conditions. In this article, the existing role of accredited exercise physiologists in interprofessional practice is examined, and an extension of their role proposed in primary health care settings

The relationships between body composition and cardiovascular risk factors in young Australian men

IntroductionCardiovascular (CV) disease is a leading cause of global mortality. Despite clear evidence of the coexistence of several risk factors in young people as children and an understanding of the importance of the health behaviors in controlling CV disease, there are limited data on the relationships between risk factors and CV disease in young people. Therefore further study is required. ObjectiveThis study aimed to investigate associations among body composition, health behaviors and CV risk factors in young Australian men. MethodsThirty five healthy men aged 18–25 years had their blood pressure (BP), blood lipids, body composition, resting metabolic rate (RMR), physical activity, dietary intake and cardiorespiratory fitness assessed. ResultsParticipants were categorised according to the percentage of body fat into two groups: lean and overweight men. There were no between-group differences in the biochemical indicators except that overweight men had lower HDL-C compared to lean men. Both groups had similar mean energy, protein, fat, carbohydrate and alcohol intake, RMR, physical activity level (PAL) and energy expenditure (EE). Most of the participants (65.7%) had LDL≥2.5 mmol/L. Other common individual risk factors were body fat≥20% (42.9%), waist circumference≥88 cm (28.6%), PAL<1.8 (22.9%) and systolic BP≥130 mmHg (20%). The mean number of CV risk factors was lower among men having a high intake of monounsaturated fatty acids (MUFA, >12% of the energy intake) regardless of whether they were overweight or lean and did not seem to differ according to the source of MUFA consumed. ConclusionsIt is a serious concern to observe such a high percentage of CV risk factors in a group of apparently healthy young men. The likelihood of multiple CV risk factors is greater among those with high body fatness and low MUFA intake. Intake of MUFA favorably affects CV risk factors regardless of the source

Food consumption of Sri Lankan adults: an appraisal of serving characteristics

Objective: The main aim of the present study was to identify food consumption in Sri Lankan adults based on serving characteristics. Design: Cross-sectional study. Fruits, vegetables, starch, meat, pulses, dairy products and added sugars in the diet were assessed with portion sizes estimated using standard methods. Setting: Twelve randomly selected clusters from the Sri Lanka Diabetes and Cardiovascular Study. Subjects: Six hundred non-institutionalized adults. Results: The daily intake of fruit (0.43), vegetable (1.73) and dairy (0.39) portions were well below national recommendations. Only 3.5 % of adults consumed the recommended 5 portions of fruits and vegetables/d; over a third of the population consumed no dairy products and fewer than 1 % of adults consumed 2 portions/d. In contrast, Sri Lankan adults consumed over 14 portions of starch and 3.5 portions of added sugars daily. Almost 70 % of those studied exceeded the upper limit of the recommendations for starch intake. The total daily number of meat and pulse portions was 2.78. Conclusions: Dietary guidelines emphasize the importance of a balanced and varied diet; however, a substantial proportion of the Sri Lankan population studied failed to achieve such a recommendation. Nutrition-related diseases in the country may be closely correlated with unhealthy eating habits

Impact of an oral nutritional supplement on improving body composition in older adults with malnutrition : A randomized controlled trial

The consequences of malnutrition in the elderly often manifest as weight loss and altered body composition. The aim of this study was to assess the efficacy of an oral nutritional supplement (ONS) on body composition in malnourished older adults
