Physical Activity and Self-Reported Metabolic Syndrome Risk Factors in the Aboriginal Population in Perth, Australia, Measured Using an Adaptation of the Global Physical Activity Questionnaire (GPAQ)

Interventions for Aboriginal and Torres Strait Islander people with type 2 diabetes that modify its management and cardiometabolic risk factors: a systematic review

OBJECTIVES

To review studies of interventions for reducing the impact of type 2 diabetes in Aboriginal and Torres Strait Islander people. The primary aim was to review and summarise the characteristics and findings of the interventions. The secondary aims were to assess their effects on diabetes and cardiometabolic risk factors, and the proportions of people with type 2 diabetes who achieved therapeutic targets with each intervention.

STUDY DESIGN

We searched eight electronic databases for publications of studies including Aboriginal or Torres Strait Islander people aged 15 years or older with diagnoses of type 2 diabetes, describing one or more diabetes interventions, and published in English during 1 January 2000 - 31 December 2020. Reference lists in the assessed articles were checked for further relevant publications.

DATA SOURCES

MEDLINE (Ovid), Web of Science (Clarivate), the Cochrane Library, Global Health (EBSCO), Indigenous Collection and Indigenous Australia (Informit), Cumulative Index to Nursing and Allied Health Literature (CINAHL), and the World Health Organization International Clinical Trials Registry Platform (WHO-ICTRP).

RESULTS

The database searches yielded 1424 unique records; after screening by title and abstract, the full text of 55 potentially relevant articles were screened, of which seventeen met our eligibility criteria: eleven cohort studies (seven retrospective audits and four prospective studies), three randomised controlled trials, and three observational, non-randomised follow-up studies. Twelve publications reported site-based (Aboriginal or Torres Strait Islander health service or diabetes clinic) rather than individual-based diabetes interventions. Interventions with statistically significant effects on mean glycated haemoglobin (HbA1c) levels were laparoscopic adjustable gastric banding, a 5-day diabetes self-management camp, treatment of Strongyloides stercoralis infections, community-based health worker-led management, point-of-care testing, and self-management approaches.

CONCLUSIONS

Few interventions for Aboriginal and Torres Strait Islander people with type 2 diabetes have been reported in peer-reviewed publications. Improving diabetes care services resulted in larger proportions of people achieving therapeutic HbA1c targets. Outcomes were better when Aboriginal and Torres Strait Islander communities were involved at all levels of an intervention. High quality studies of holistic, culturally safe and accessible interventions should be the focus of research.

A scoping review of Indigenous community-specific physical activity measures developed with and for Indigenous Peoples in Canada, Australia, and New Zealand

Historical factors including colonization and ongoing socioeconomic inequities impact Indigenous Peoples' ability to mitigate chronic disease risks such as achieving recommended physical activity (PA) levels. Reliably assessing, reflecting, and promoting PA participation among Indigenous Peoples may be impacted by a lack of culturally appropriate assessment methods and meaningful engagement with Indigenous communities throughout the research process. The objectives of this scoping review were to examine: (1) How PA research with Indigenous Peoples used community-specific PA measures developed with and/or for Indigenous Peoples in Canada, Australia, and New Zealand; and (2) How the studies utilized community-based participatory research (CBPR) principles to engage communities. A systematic search was conducted in four electronic databases (Web of Science, Medline, University of Saskatchewan Indigenous Portal, and ProQuest Dissertations and Theses Global). Thirty-one (n = 31) articles were identified and data extracted for narrative synthesis. Studies using community-specific PA measures have been increasing over time. Adapting questionnaires to traditional Indigenous activities such as cultural dances, ceremonies, and food-gathering activities were the most frequent adjustments undertaken to use community-specific measures. There are, however, gaps in research partnering with communities with only 6% of studies including all eight CBPR principles. Practical ways researchers can engage Indigenous communities and build capacity such as training and employing community members were highlighted. More needs to be done to facilitate community self-determination and develop long-term sustainable initiatives. Using culturally appropriate and relevant methodologies including partnering with Indigenous communities may help identification and implementation of culturally relevant and sustainable health-promoting initiatives.

Effect of High-Intensity Strength and Endurance Training in the Form of Small Circuits on Changes in Lipid Levels in Men Aged 35–40 Years

Background: Blood lipid profiles consist of total cholesterol (TC) and its fractions, high-density lipoprotein cholesterol (HDL), low-density lipoprotein cholesterol (LDL), non-high-density lipoprotein cholesterol (non-HDL), and triglycerides (TG). For several decades, studies have examined the effects of various factors on lipid status and its association with the risk of developing arteriosclerosis and cardiovascular disease. The beneficial effects of increased physical activity on cardiovascular health have been demonstrated by appropriate modulation of lipid profiles. For individuals with low physical activity, the literature recommends engaging in various forms of training that can improve physical fitness and resting lipid status. The aim of the study was to examine whether a specific original training program improves lipid profiles to the levels recommended for the male population. Methods: The study involved two equal (n = 15) groups of men (experimental and control groups, aged 35–40 years). The experimental group performed 60-min training sessions for 8 weeks (3 times a week) including a set of strength and endurance exercises. Before and after the training program, blood was drawn from both groups for serum determination of TC, HDL, LDL non-HDL, and TG, and a battery of four field physical performance tests was administered. Results: Statistically significant decreases (TC by 19.3%, TG by 23.7%, LDL by 15%), a non-significant decrease (10% for non-HDL), and no change for HDL were found in the experimental group. Control group showed a statistically significant decrease, by 7.4% for TC. The results confirm the effectiveness of the proposed training in improving health indices. Conclusions: The 8-week training program met the health-related fitness paradigm recommended for physical activity in men aged 35–40 years. After the completion of the program, all the participants expressed their satisfaction from participating in a health-promoting experiment.

Associations of occupational and leisure-time physical activity with self-rated health in Korea

Recent findings have suggested that not all physical activity (PA) types improve health and that the health effects of occupational PA (OPA) and leisure-time PA (LTPA) can be different. However, few studies have been reported the association of OPA and LTPA with self-rated health (SRH). Therefore, we aimed to examine the association between different PA domains and general health and the impact of LTPA on the relationship between health and OPA. In total, 33440 adults from the Korea National Health and Nutrition Examination Survey 2014-2019 were analyzed in September 2021. SRH was dichotomized into "poor" and "good." Sedentary behavior (SB) was evaluated by measuring the daily sitting time. Multiple logistic regression was used to investigate the relationship of SRH with OPA, LTPA, and SB, stratified by LTPA to identify its impact on the relationship. In the fully adjusted model, OPA was found to increase the risk of poor SRH, while LTPA was found to lower the risk. In those who did not engage in LTPA, OPA and poor SRH were significantly associated. Poor SRH was not significantly associated with OPA in those who engaged in LTPA. SB was also associated with poor SRH, independent of LTPA. To improve health, it is important to promote LTPA and reduce OPA and SB. In particular, for workers with a higher level of OPA, additional LTPA should be introduced to prevent SRH from worsening.
