Body composition measurements, definitions of HALS and metabolic syndrome have been described elsewhere [20].
However, the survey showed that many programs and facilities had no processes in place to measure treatment adherence or defaulting at either the patient or program level, and among those facilities that did conduct measurements, definitions and data collection practices varied widely, although they routinely collected useful data [ 26].
The choice of measurement model can be made more explicit based on consideration of the purpose of measurement, definition of the latent construct, and the relevance of measured items to respondents within the target population.
Although this review found that the concept of body awareness is widely used, it also revealed important limitations to the current approaches in understanding the meaning of measures of body awareness: First, there is no widely accepted unifying measurement definition.
The reasons of this discrepancies are likely multifactorial e.g., differences in study design, setting, data measurement, definition of outcomes, or any combination of these factors.
However, Cohen et al. [3] claimed that the comparison between those sources may not be valid since a consistent measurement definition is needed and it should be validated over several years of data collection.
Differences in measurement, definition and context, however, can influence reported adherence rates, correlates and outcomes [ 3].
No golden standard currently exists for the measurement, definition, and assessment of ADEs [ 25, 26].
Results may differ across investigations because of variations in study design, confounder control, metal measurement, definition or measurement of the BP outcome, manganese exposure level, and participant characteristics.
