Abstract

OBJECTIVES

To evaluate the prevalence of low energy reporting (LER) and associations between LER and lifestyle, psychological and clinical parameters, in elderly people living in eastern Mediterranean islands.

METHODS

1190 men and women, aged 65-100 years, participated in this cross-sectional study. Socio-demographic, clinical and lifestyle characteristics were recorded for the study participants. Among others, the ratio of energy intake to estimated basal metabolic rate (EI/BMR) was calculated and was used for the assessment of LER.

RESULTS

Prevalence of LER was 47.7%. Lower EI/BMR (i.e., higher risk for LER) was associated with older age (p=0.001), male sex (p<0.001), higher body mass index (BMI; p=0.04), lower adherence to the Mediterranean diet (p<0.001) and non-current smoking (p=0.007). The sex-specific analysis revealed that, lower EI/BMR values were associated with lower adherence to the Mediterranean diet and being non-current smoker in both men and women (p≤0.05), as well as with older age (p=0.01), higher BMI (p=0.02) and hypercholesterolemia (p=0.02), only in women.

CONCLUSION

In elderly, several clinical and lifestyle factors seem to be related to LER, and they should be taken into account in their nutritional assessment.

摘要

目的

评估东地中海岛屿上居住的老年人中低能量报告（LER）的流行情况，以及 LER 与生活方式、心理和临床参数之间的关联。

方法

本横断面研究纳入了 1190 名年龄在 65-100 岁的男性和女性。为研究参与者记录了社会人口统计学、临床和生活方式特征。其中，计算了能量摄入与估计基础代谢率（EI/BMR）的比值，并用于评估 LER。

结果

LER 的患病率为 47.7%。较低的 EI/BMR（即更高的 LER 风险）与年龄较大（p=0.001）、男性（p<0.001）、较高的体重指数（BMI；p=0.04）、较低的地中海饮食依从性（p<0.001）和非当前吸烟者（p=0.007）有关。性别特异性分析表明，较低的 EI/BMR 值与男性和女性的地中海饮食依从性较低和非当前吸烟者有关（p≤0.05），以及与年龄较大（p=0.01）、较高的 BMI（p=0.02）和高胆固醇血症（p=0.02）有关，仅在女性中。
