Identifying those seniors most likely to adopt a healthy diet, the relative importance they place on certain perceived benefits associated with a healthy diet, and whether these perceived benefits are associated with selected demographic, lifestyle, and health history variables is important for directing effective dietary health promotion programs.
Analyses are based on a cross-sectional convenience sample of 670 seniors aged 50 years and older at the 2002 World Senior Games in St. George, Utah. Data are assessed using frequencies, bivariate analysis, analysis of variance, and multiple logistic regression analysis.
Fruit and vegetable consumption was significantly higher in individuals aged 70-79, in women, in those not overweight or obese, and in those with excellent overall health. Dietary fiber consumption was significantly higher in former or never smokers, current and previous alcohol drinkers, in those not overweight or obese, and in those with excellent health. The strongest motivating factors identified for adopting a healthy diet were to improve the quality of life, to increase longevity, and to prevent disease. Of intermediate importance were the need to feel a sense of control and to satisfy likes or dislikes. Least important were the desire to experience a higher level of spirituality, social reasons, and peer acceptance.
Seniors who have adopted a healthy diet are more likely to have chosen that behavior because of perceived health benefits than for personal and social benefits. Overweight or obese individuals and those in poor health were less likely to be engaged in healthy eating behavior and require special attention by dieticians and public health professionals.
确定哪些老年人最有可能采用健康饮食,他们对与健康饮食相关的某些感知益处所赋予的相对重要性,以及这些感知益处是否与选定的人口统计学、生活方式和健康史变量相关,对于指导有效的饮食健康促进项目很重要。
分析基于2002年在犹他州圣乔治举行的世界老年人运动会上670名50岁及以上老年人的横断面便利样本。使用频率、双变量分析、方差分析和多元逻辑回归分析来评估数据。
70 - 79岁的个体、女性、非超重或肥胖者以及总体健康状况极佳者的水果和蔬菜摄入量显著更高。曾经吸烟或从不吸烟、目前和以前饮酒者、非超重或肥胖者以及健康状况极佳者的膳食纤维摄入量显著更高。确定的采用健康饮食的最强烈动机因素是改善生活质量、延长寿命和预防疾病。中等重要性的是需要有控制感以及满足喜好。最不重要的是体验更高精神层面的愿望、社交原因和同伴认可。
采用健康饮食的老年人更有可能是因为感知到健康益处而非个人和社交益处而选择这种行为。超重或肥胖个体以及健康状况不佳者从事健康饮食行为的可能性较小,需要营养师和公共卫生专业人员给予特别关注。
