An assessment of non-communicable diseases, diabetes, and related risk factors in the territory of American Samoa: a systems perspective.

Non-communicable diseases (NCD) have been identified as a health emergency in the US-affiliated Pacific Islands (USAPI).1 This assessment, funded by the National Institutes of Health, was conducted in American Samoa and describes the burden of selected NCDs (ie, diabetes, heart disease, hypertension, stroke, and chronic kidney disease); and assesses the system of service capacity and activities regarding service delivery, data collection and reporting as well as identifies the issues needing to be addressed. Findings reveal that nutrient-poor diet, lack of physical activity, and other lifestyle behaviors are associated with overweight and obesity and subsequent NCDs that impact the morbidity and mortality of the population.

Chronic disease surveillance systems within the US Associated Pacific Island jurisdictions.

In recent years, illness and death due to chronic disease in the US Associated Pacific Islands (USAPI) jurisdictions have dramatically increased. Effective chronic disease surveillance can help monitor disease trends, evaluate public policy, prioritize resource allocation, and guide program planning, evaluation, and research. Although chronic disease surveillance is being conducted in the USAPI, no recently published capacity assessments for chronic disease surveillance are available.

The maximally accumulated oxygen deficit as an indicator of anaerobic capacity.

Recently, a procedure has been established for the determination of the maximally accumulated oxygen deficit (MAOD) (Medbo et al., J. Appl.

Ratings of Perceived Exertion, Heart Rate, and Power Output in Predicting Maximal Oxygen Uptake During Submaximal Cycle Ergometry.

In brief: Sixty-two subjects completed a four- stage submaximal cycle ergometer test to volitional fatigue. The purpose was to determine if estimates of V O2 max could be improved by using ratings of perceived exertion singly or in combination with easily obtainable physiological measures during submaximal cycle ergometry. While these procedures may not be acceptable for scientific purposes, clinicians could use them to estimate the aerobic power of their patients and athletes.

Acid-base, metabolic, and ventilatory responses to repeated bouts of exercise.

Acid-base, metabolic, and ventilatory responses to repeated bouts of exercise were examined. Ten male subjects performed two (T1, T2) 5-min work tests, on a cycle ergometer, separated by a 25-min rest. The results indicate the following.
