title: Correlates of low dietary energy reporting in free-living elderly: the MEDIS study.
abstract: OBJECTIVE
  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.
  
  
  CONCLUSIONS
  In elderly, several clinical and lifestyle factors seem to be related to LER, and they should be taken into account in their nutritional assessment.
