Community-based exercise assessment in children with high risk for type 2 diabetes

A Systematic Review of Musculoskeletal Fitness Among Indigenous Populations in North America and Circumpolar Inuit Populations

BACKGROUND

North American indigenous populations experience higher rates of obesity and chronic disease compared with nonindigenous populations. Improvements in musculoskeletal fitness can mitigate negative health outcomes, but is not well understood among indigenous populations. This review examines musculoskeletal fitness measures among North American indigenous populations.

METHODS

A total of 1632 citations were evaluated and 18 studies were included.

RESULTS

Comparisons of musculoskeletal fitness measures between North American indigenous men and boys and women and girls were generally not reported. The greatest left and right combined maximal grip strength and maximal leg strength among Inuit boys and men and girls and women were observed among 20-29 years age group. Maximal combined right and left grip strength declined from 1970 to 1990, by an average of 15% among adults and 10% among youth. Maximal leg extension among Inuit has declined even further, averaging 38% among adults and 27% among youth from 1970 to 1990. Inuit men demonstrate greater grip strength and lower leg strength than Russian indigenous men, whereas Inuit women demonstrate greater leg strength.

CONCLUSIONS

Further research is needed to better understand physical fitness among indigenous peoples and the potential for improving health and reducing chronic disease risk for indigenous peoples through physical fitness.

Anthropometric measurements in Canadian children: a scoping review

OBJECTIVE

The objective of the current study was to identify what forms of anthropometric measurement are currently being utilized with Canadian children and youth and what are the gaps in the literature on this topic.

METHODS

The current study utilized a scoping review methodology in order to achieve the study objectives. Online databases Medline and PubMed and CINAHL were used to search articles from the last decade (2002-2012) that addressed Canadian children aged 2-18 years.

SYNTHESIS

50 studies were included in this review. A variety of anthropometric measurements were identified, including body mass index, waist circumference, hip-to-waist ratio, among others. Six of the included studies (12%) utilized nationally representative data from large-scale studies. BMI was the most reported form of measurement with 88% of studies collecting it. Waist circumference was a distant second with 20% of studies reporting it. Several gaps in the literature exist with regards to First Nations (FN) research; many of the measurement methods were not used. Additionally, FN accounted for only 2.5% of the study's sample. The majority of studies took place in Quebec (29%) and Ontario (27%).

CONCLUSION

Body mass index is the most reported method of anthropometric measurement used for children. Efforts should be taken by health care practitioners and researchers to collect other forms of measurement in order to assist in understanding the validity of other measures and their value when used with children. Furthermore, attention needs to be focused on utilizing and studying various forms of anthropometric measurement across all Canadian regions and populations.

[Physical activity among aboriginals in Canada]

This paper summarizes available information on patterns of physical activity, their determinants and consequences, and the results of various interventions designed to increase the physical activity of Aboriginal peoples in Canada and the United States. There is a paucity of national data on this issue for Aboriginal peoples. The most recent data, from the First Nations Regional Longitudinal Health Survey of 2002-2003, indicate that 21% of adults (27% of men, 15% of women) were engaging in at least 30 min of moderate to vigorous physical activity on 4 d/week or more. The present paper highlights the unique challenges this group faces, underlining the need to integrate collective knowledge regarding how much physical activity is required for Aboriginal Canadians, and how this activity should be accomplished, to promote and maintain health. Efforts are currently underway to tailor Canada's physical activity guide for First Nations, Inuit, and Métis. Future research among Aboriginal groups should examine the minimal and optimal levels of physical activity required to achieve health benefits.

Fitness, motor competence and body composition as correlates of adolescent neck/shoulder pain: an exploratory cross-sectional study

Background

Adolescent neck/shoulder pain (NSP) is a common and sometimes debilitating problem. Several risk factors for this condition have been investigated, but no studies have previously evaluated associations between fitness, motor competence, body composition and adolescent NSP.

Methods

1608 males and females of mean age 14 years answered questions on their history of NSP (4 measures), and were tested for aerobic fitness, upper and lower limb power, trunk endurance, grip strength, shoulder flexibility, motor competence and anthropometric factors. Univariate and multivariate logistic regressions were used to test for associations between NSP and physical variables.

Results

There were significant gender differences for most physical and pain variables. After multivariate analysis, males had lower odds of NSP if they had reduced back endurance [OR: 0.66 (95% CI: 0.46–0.97)], reduced persistent control [0.42 (0.19–0.95], and increased muscle power [0.33 (0.12–0.94)], and higher odds of NSP if they had a higher basketball throw [2.47 (1.22–5.00)] and jump performance [3.47 (1.55–7.74)]. Females had lower odds for NSP if they had a reduced jump performance [0.61(0.41–0.92)], a better basketball throw [0.60(0.40–0.90)], lower shoulder flexibility [0.54 (0.30–0.98)] and a higher aerobic capacity [0.61 (0.40–0.93)], and higher odds for NSP if they had greater abdominal endurance [1.57(1.07–2.31)] and greater bimanual dexterity [1.77(1.18–2.65)]. Females showed a U shaped relationship between NSP and back endurance [low: 2.12 (1.20–3.74); high 2.12 (1.18–3.83)].

Conclusion

Adolescent NSP was associated with fitness and motor competence, although the associations varied with gender, and their strength was limited.
