    Physical activity recommendations for older Australians

    Jane Sims
    Aim:, The aim of this research was to produce evidence-based recommendations on physical activity designed to improve and maintain the health of older Australians. Methods:, The authors reviewed existing guidelines and consensus statements, systematic reviews, meta-analyses and research articles. Draft recommendations were circulated to stakeholder agencies and to an expert advisory group. Final recommendations were then forwarded to the Commonwealth Department of Health and Ageing for Ministerial approval. Results:, The physical activity recommendations for older Australians complement the current National Physical Activity Guidelines for adults and the American College of Sports Medicine and American Heart Association recommendations for older adults. The recommendations provide advice developed specifically for older Australians. Conclusion:, Although the recommendations may be manifested in different ways, according to specific populations or settings, they apply to older people across all levels of health and have application to community dwelling people and those in residential care accommodation.

    Aerobic exercise training reduces hepatic and visceral lipids in obese individuals without weight loss,

    HEPATOLOGY, Issue 4 2009
    Nathan A. Johnson
    Weight loss remains the most common therapy advocated for reducing hepatic lipid in obesity and nonalcoholic fatty liver disease. Yet, reduction of body weight by lifestyle intervention is often modest, and thus, therapies which effectively modulate the burden of fatty liver but are not contingent upon weight loss are of the highest practical significance. However, the effect of aerobic exercise on liver fat independent of weight loss has not been clarified. We assessed the effect of aerobic exercise training on hepatic, blood, abdominal and muscle lipids in 19 sedentary obese men and women using magnetic resonance imaging and proton magnetic resonance spectroscopy (1H-MRS). Four weeks of aerobic cycling exercise, in accordance with current physical activity guidelines, significantly reduced visceral adipose tissue volume by 12% (P < 0.01) and hepatic triglyceride concentration by 21% (P < 0.05). This was associated with a significant (14%) reduction in plasma free fatty acids (P < 0.05). Exercise training did not alter body weight, vastus lateralis intramyocellular triglyceride concentration, abdominal subcutaneous adipose tissue volume, 1H-MRS,measured hepatic lipid saturation, or HOMA-IR (homeostasis model assessment of insulin resistance; P > 0.05). Conclusion: These data provide the first direct experimental evidence demonstrating that regular aerobic exercise reduces hepatic lipids in obesity even in the absence of body weight reduction. Physical activity should be strongly promoted for the management of fatty liver, the benefits of which are not exclusively contingent upon weight loss. (HEPATOLOGY 2009.) [source]

    A Culturally Appropriate School Wellness Initiative: Results of a 2-Year Pilot Intervention in 2 Jewish Schools

    Maureen R. Benjamins PhD
    BACKGROUND: Despite the growing number of school-based interventions designed to reduce childhood obesity or otherwise promote health, no models or materials were found for Jewish schools. The current study describes an effort within a Jewish school system in Chicago to create, implement, and evaluate a school-based intervention tailored to the unique characteristics of Jewish religion, culture, and school structures. METHODS: Two schools (with approximately 600 students) were selected for the 2-year pilot study. The schools were required to form a wellness council, write a wellness policy, and implement policy changes or activities in 5 target areas (health education, physical education, school environment, family involvement, and staff wellness). Objectives were measured using pre- and postintervention surveys for students, as well as the School Health Index and other tools. RESULTS: Findings showed several significant increases in student knowledge, as well as an increase in the percentage of older students regularly meeting physical activity guidelines. Few changes in attitudes, other behaviors, or environmental factors were seen. CONCLUSIONS: Due to a strong partnership between researchers, schools, and community organizations, meaningful changes were made within the pilot schools. These changes were reflected in a limited number of improvements in student knowledge and activity levels. Future work is needed to determine how to bring about behavioral changes, how to increase the sustainability of all of the changes, and how to disseminate the model and products of this intervention to other day schools.

    Physical activity trends in Queensland (2002 to 2008): are women becoming more active than men?

    Corneel Vandelanotte
    Abstract Objective: Regular monitoring of population levels of physical activity is an effective way to assess change over time towards meeting public health recommendations. The objective of this study was to determine physical activity trends in Central Queensland over the period 2002 to 2008. Methods: Data was obtained from the Central Queensland Social Survey (CQSS) conducted annually from 2002 to 2008. A total sample of 8,936 adults aged 18 and over participated in seven cross-sectional surveys. Physical activity was measured using the Active Australia Questionnaire. Binary logistic regression was used to examine trends in sufficient physical activity. Results: Averaged over all survey years 46.5% of study participants met national physical activity guidelines. A small significant upward trend was found for meeting physical activity recommendations across all years (OR=1.03; 95%CI=1.01,1.05), indicating that the odds of meeting the guidelines increased by an average of 3% per year from 2002 to 2008. Slightly more men than women met the activity guidelines (ns); however a significant positive trend in achieving sufficient activity levels was present in women only (4%). Conclusions and Implications: Although an increasing trend for sufficient physical activity was observed, overall physical activity levels in Central Queensland remain suboptimal and more efforts to increase physical activity are needed. The gender differences in physical activity trends indicate that men and women might need to be targeted differently in health promotion messages. The continuous monitoring of population levels of physical activity in Australia, which allow both state specific and international comparisons, is needed. [source]
