ABSTRACT:

Background

To investigate the associations between the body mass index (BMI), Mini Nutritional Assessment-Short Form (MNA-SF) scores, and 2-year mortality.

Methods

A nationwide cohort study using data from a national quality register of older (age ≥ 65 years) nursing home residents (N = 47,686). Individuals were categorized according to BMI as underweight (< 18.5 kg/m²), normal-weight (18.5-24.9 kg/m²), overweight (25.0-29.9 kg/m²), and obese (class I, 30.0-34.9 kg/m²; class II, 35.0-39.9 kg/m²; class III, ≥ 40.0 kg/m²). Participants' nutritional status were categorized as good (MNA-SF score 12-14), at risk of malnutrition (MNA-SF score 8-11), or malnutrition (MNA-SF score 0-7). Associations with mortality wer
