Nutritional Epidemiology in Aging

摘要: Epidemiologists have attempted to identify nutritional factors associated with the preservation of health and function in older adults. A number methods are available for identifying patterns dietary intake that health, including specific nutrients; factor or cluster analysis foods co-consumed a given population; studies priori based on prevailing hypotheses regarding role nutrients disease prevention; combined method identifies food explain variation set intermediate response variables, then examines association between pattern outcome interest. Methods assessing usual include methodologies fall into two broad strategies: interview/questionnaire-based biomarkers exposure. The reliability validity recalled data adults is concern; combine recall-based exposure can be used help improve data. been hypothesized affect age-related disability processes, omega-3 fatty acids, protein, vitamin D, calcium, B vitamins antioxidants. While identification slow changes has met limited success, general good low levels chronic identified.
