Association between nut consumption and frailty in the elderly: a large sample cross-sectional study

Area of Science:

• Gerontology
• Nutritional Science
• Public Health

Background:

• Frailty is a growing concern in aging populations.
• Limited research exists on the role of nut consumption in mitigating frailty.
• Understanding dietary factors like nut intake is crucial for healthy aging.

Purpose of the Study:

• To investigate the association between nut consumption and frailty in US adults aged 60 and older.
• To identify potential thresholds for nut intake associated with reduced frailty risk.
• To explore subgroup differences in the nut-frailty relationship.

Main Methods:

• Utilized National Health and Nutrition Examination Survey (NHANES) data (2003-2018).
• Employed weighted multiple logistic regression and restricted cubic spline models.
• Conducted stratified and interaction analyses to assess subgroup effects.

Main Results:

• A total of 10,033 individuals (aged ≥60) were analyzed; 3591 were frail, and 5302 consumed nuts.
• Nut consumption was associated with a lower prevalence of frailty in adjusted analyses.
• An optimal intake threshold of approximately 1.02 ounces/day was identified for reducing frailty risk.

Conclusions:

• Nut consumption positively impacts frailty prevention in older adults.
• The protective effect is particularly notable in nonhypertensive individuals.
• Daily nut intake of ~1.02 ounces may enhance quality of life for the elderly.
