BACKGROUND/AIM: To be aware of the influencing factors of healthy aging, several cross-sectional surveys have been carried out among the elderly living in Austria to identify health and lifestyle factors as well as socioeconomic influences that contribute to the nutritional situation.
Information about the health situation was collected by questionnaires. Diet was assessed by both qualitative food frequency questionnaires and 24-hour recalls. Additionally, nutritional status was examined in blood and urine samples using static and functional parameters.
The prevalence of overweight (21%, BMI >29) and obesity increased with increasing age up to 65 years; in people older than 65 years an inverse tendency could be observed; as from this age upwards a high prevalence of underweight was found (22%, BMI <24). The consumption of meat and meat products was too high compared to the recommendations. By contrast, the intake of high nutrient density foods was insufficient. On average, the fat intake was around 38% of total energy (%E); that of saturated fatty acids amounted to 20%E; the intake of carbohydrate and fiber was considered as being too low. The intake of folate, vitamin D, calcium, iodine, magnesium and vitamin C was assessed as inadequate.
More attention has to be paid to certain micronutrients in order to optimize dietary intake and to sustain health.
背景/目的:为了解健康老龄化的影响因素,在奥地利的老年人中开展了多项横断面调查,以确定对营养状况有影响的健康和生活方式因素以及社会经济因素。
通过问卷调查收集健康状况信息。采用定性食物频率问卷和24小时膳食回顾法评估饮食情况。此外,利用静态和功能参数对血液和尿液样本进行营养状况检测。
超重(21%,BMI>29)和肥胖的患病率随年龄增长至65岁而上升;65岁以上人群中则观察到相反趋势;从这个年龄起,发现体重不足的患病率较高(22%,BMI<24)。与建议相比,肉类和肉制品的消费量过高。相比之下,高营养密度食物的摄入量不足。平均而言,脂肪摄入量约占总能量的38%(%E);饱和脂肪酸摄入量为20%E;碳水化合物和纤维的摄入量被认为过低。叶酸、维生素D、钙、碘、镁和维生素C的摄入量评估为不足。
必须更加关注某些微量营养素,以优化饮食摄入并维持健康。
