The aim of this study was to evaluate sex- and age-related variations of the nutritional status in the aged population of central Sardinia, a geographical area with a high frequency of long-lived people, particularly men.
The sample consisted of 200 subjects over 70 years of age (men: N= 100, age= 81.0 +/- 7.0 years; women: N= 100, age= 81.5 +/- 7.3 years).
Orroli (central Sardinia, Italy).
Mini nutritional assessment (MNA) and bioelectrical impedance vector analysis (BIVA) were used to evaluate nutritional status and body composition.
The indicators revealed a generally good nutritional status. The MNA results (men: 24.6 +/- 2.2; women: 23.4 +/- 2.5) showed that 64.1% of the subjects had a normal nutritional status and only a small proportion (1.2%) could be classified as malnourished. BIVA showed that most subjects (74.2%) were normal, while the prevalence of low body cell mass was 10.7% and that of dehydration 11.2%. According to the MNA, the nutritional status was significantly better in the men. Almost three-quarters of the men (73.1%) were well nourished vs. half of the women (50.6%). A worsening of the nutritional status with age was observed. The proportion of malnourished individuals, as assessed by MNA, increased from 0% to 9.1% from 70-79 to > 90 years.
With respect to their contemporaries from other regions, the elderly of Orroli presented a better nutritional status, a similar worsening with age and generally higher sexual dimorphism.
本研究旨在评估撒丁岛中部老年人群的营养状况，该地区是一个长寿人群（尤其是男性）比例较高的地理区域。
该样本由 200 名 70 岁以上的受试者组成（男性：N=100，年龄=81.0 +/- 7.0 岁；女性：N=100，年龄=81.5 +/- 7.3 岁）。
意大利奥尔罗利（撒丁岛中部）。
采用微型营养评定（MNA）和生物电阻抗向量分析（BIVA）来评估营养状况和身体成分。
各项指标显示出总体良好的营养状况。MNA 结果（男性：24.6 +/- 2.2；女性：23.4 +/- 2.5）表明，64.1%的受试者营养状况正常，只有很小比例（1.2%）可被归类为营养不良。BIVA 显示，大多数受试者（74.2%）正常，而低体细胞量的患病率为 10.7%，脱水的患病率为 11.2%。根据 MNA，男性的营养状况明显更好。73.1%的男性营养良好，而女性只有一半（50.6%）。随着年龄的增长，营养状况恶化。根据 MNA 评估，营养不良的人数从 70-79 岁到>90 岁增加了 0%到 9.1%。
与其他地区的同龄人相比，奥尔罗利的老年人营养状况更好，年龄相关性变差相似，性别差异更大。
