Diabetes and Obesity in Young Children

Research Question

Discuss about the Diabetes and obesity in young children and adolescents in Australia.

This report is focused on the prevalence of diabetes and obesity in Australia.  Physical inactivity is regarded as one of the risk factor of chronic disease burden in Australia. More than half of Australian adults do not engage in adequate physical activity as per the recommended guidelines and physical inactivity is linked to high percentage of disease burden for diabetes (Australian Institute of Health and Welfare, 2017). Due to such link, exploring the impact of exercise on reducing diabetes and obesity in Australia is considered important. The main research question to explore the effect of exercise on diabetes and obesity prevalence in Australia is as follows:

Do regular exercise (I) reduce the incidence of diabetes and obesity (O) compared to no exercise (C) in young children and adolescent in Australia (P)?

The research is concerned with the prevalence of diabetes and obesity in young children and adolescent in Australia. Diabetes is turning out to be an epidemic in Australia and it is presenting biggest challenge to the health system of the country. The rate at which the incidence of diabetes occurs in Australia is understood from the fact that about 1.2 million people aged 2 years and above have been diagnosed with diabetes in Australia (The Department of Health, 2017). Another challenge for the Australian health care system is the prevalence of diabetes in children and young people. Around 4000 new cases of type 2 diabetes was observed among 10-24 year old in 2011-2012 (The Department of Health, 2014). Obesity, poor diet and inadequate physical activity is regarded as the main risk factor of diabetes in Australia. This can be said by the review of obesity statistics in Australia. More than half of the Australian population has abnormal body weight. 285 of Australian adults were obese in 2014-2015 and one in every four Australian children (2-17 years old) were obese or overweight (Australian Institute of Health and Welfare, 2015).  Prevalence Of Diabetes And Obesity In Young Children And Adolescents In Australia Discussion Paper

The main aim of the research is to investigate about the impact of exercise in reducing

the prevalence of diabetes and obesity in children and young people in Australia. This is considered important because sedentary behavior increases risk of diabetes and exercise has the potential to reduce the risk in vulnerable population (Rockette-Wagner et al., 2015). The topic of diabetes and obesity prevalence in children and adolescent is linked to the National Strategic framework for chronic diseases because the framework focuses on prevention and management of chronic disease condition to provide healthy life to all Australians. Diabetes is listed as one of the chronic disease in the national framework and evaluating the effectiveness of exercise as an intervention for diabetes and obesity may help to promote health and reduce risk in children and adolescent population of Australia (health.gov.au., 2017). Physical exercise is part of life-style intervention and it may help to reduce the burden of diabetes in Australia.

Research Topic

The review of research literature gave clear insight regarding the effectiveness of exercise to reduce risk of diabetes and obesity in children and adolescent. Davis et al. (2012) investigated about the effect of aerobic exercise dose on insulin resistance and fatness in overweight children. The population group and the research objective is congruent t the research question. By employing randomized controlled trial as a study design, the research participants were randomly assigned to low dose or high d11ose aerobic training group (intervention group) and control condition (usual physical activity). The aerobic exercise intervention was offered for 10 to 15 weeks and children in the  high dose group received 40 minutes exercise per day compared to low dose group who received 20 minute exercise/day. The evaluation of primary and secondary outcome revealed that effect of high or low dose was similar and aerobic training improved fitness and had positive impact on insulin resistance, adiposity and overweight. Hence, safe dose of vigorous physical activity can reduce risk of diabetes and obesity in children.

Another research that is relevant to address the research question is the study by Stoner et al. (2016) which aimed to evaluate whether exercise intervention can improve body weight and reduce risk of obesity in adolescents or not. The Meta-analysis of randomized controlled trials included those studies which had structured exercise intervention and a control group that received no exercise or received behavioral intervention. Prevalence Of Diabetes And Obesity In Young Children And Adolescents In Australia Discussion Paper The review of all included studies showed variability in exercise intervention, however robust evidence for reduction in BMI was found following exercise intervention. Although the meta-analysis identified very few RCT trials, however the study gave evidence to prove that exercise intervention lead to moderate decrease in BMI, waist circumference and body fat. Hence, from this perspective, exercise can be considered as an intervention to reduce the risk factor of diabetes.

A separate randomized controlled trial also evaluated supervised exercise on prevention of diabetes in overweight children. Moderate reduction in obesity among adolescents was observed, however the limitation was that it did not analyzed effect of exercise separately (Hollis et al., 2016).  Another randomized controlled trial compared effect of low-intensity exercise and no exercise on abdominal obesity and glucose tolerance in obese individuals. Hence, credibility and reliability of such evidence is high. It was a single center parallel group trial and 300 obese individuals as research participant. The primary outcome for the study was waist circumference and 2-hour glucose level. The intervention group performed walk/jog exercise on treadmill  times per week for 24 weeks and the control group received no exercise intervention. However, the factor that was similar for both the group was that both group received diet composition advice. Primary outcome variable was waist circumference and 2-hour glucose level and secondary measurement was cardio-respiratory fitness. The outcome of the research proved that exercise intervention consistent to current guideline are effective in reducing abdominal obesity irrespective of the intensity of exercise (Ross et al., 2015). However, the research showed that to achieve glucose tolerance level, high intensity exercise was needed to achieve desired outcome. The review of additional evidence to validate the result that high intensity was needed to achieve desired outcome showed that there is lack of robust evidence to prove the effect of high-intensity exercise on blood glucose level (Adams, 2013). Hence, large scale randomized trial may confirm the result in future.

Literature Review

From the review of research literature related to research question, the evidence by Ross et al. (2015) is the best evidence to address the research question because it had similar intervention and comparator like the research question. Secondly, it is high quality evidence because it used randomized control study design and such research design comes under top level in the hierarchy of evidence. Another rational for regarding it as the best evidence to address the research question is that by the use of abdominal obesity and glucose tolerance as a primary outcome variable, it clearly gave evidence regarding the impact of exercise on both diabetes and obesity in high risk individual. This evidence has been regarded as a high quality research evidence also because of methodological rigor. The research had adequate sample size and requirement for randomization and blinding was fulfilled. Ethical consideration related to informed consent approach for research was also done. All lost to follow-up and number of participants in follow-up was also analyzed. Another strength of the study is strong adherence to excellent exercise regimen. Hence, nurse practitioner can use the evidence as a guide to support children and adolescent in Australia to engage in low intensity exercise and maintain healthy weight.

The nurse working in primary care and Australian health department can prioritize exercise as an intervention to reduce incidence of diabetes and obesity and improve health outcome of the target population. By the use of outcome from the study by Ross et al. (2015), nurse working in diabetes prevention program in Australia can collaborate with other health staff to implement low-intensity exercise for children and adolescent at risk of obesity and diabetes. They can also utilized method used in the study to improve adherence to the exercise program and promote heath of Australian population as per the goal of the National Strategic framework for chronic disease (Whittemore et al., 2013).

Based on the review of research evidence, it was found that strong evidence was found for impact of exercise on weight loss and reducing obesity. However, one finding that could not be effectively analyzed was the impact of high intensity exercise on glucose tolerance level. Several studies investigated effect of low and high density exercise. However, enough evidence could not be found regarding the claim that high intensity exercise regimen reduces 2 hours glucose level. The finding was not reliable because many participants in the high-intensity group lost to follow-up and adherence level was low in those groups. Hence, it is recommended that future randomized controlled trial should study the effect of high-intensity exercise on heterogeneous population group such as those at risk of diabetes and those without risk. In addition, adequate sample size should be taken so that research finding can be generalized. Strict measures for adherence to the program should also be done so that high intensity exercise can be implemented by nurses to prevent diabetes.
