Relation Between Handgrip Strength and Loneliness in Community-Dwelling Older People

Abstract

Background: Handgrip strength (HGS) is associated with older people’s functional independence, facilitating autonomous living and active participation in daily, professional and social activities. HGS is an essential indicator of overall physical and functional capacity, playing a fundamental role in promoting independence and well-being. Loneliness has been associated with loss of functional capacity. Objectives: To assess handgrip strength and analyse its relationship with the level of loneliness. Methods: A descriptive-correlational, cross-sectional study was conducted using a convenience sample of 33 older people (≥65 years), 82% female, with a mean age of 70.85 (±6.99) years. HGS was measured using a Baseline BIMS dynamometer and loneliness was assessed using the UCLA Loneliness Scale validated for the Portuguese population. Correlations between HGS and loneliness score were analysed. Results: Mean non-dominant handgrip strength (NDHGS) was 24.05 (±6.86) kg in males and 28,40 (± 15,8) kg in females. Although a trend towards a negative correlation between loneliness and handgrip strength was observed, this correlation was not statistically significant. Conclusion: A correlation between loneliness and handgrip strength in older adults cannot be established. Nevertheless, handgrip strength remains a useful measure for identifying the risk of physical decline. Further studies are needed to clarify the interactions between handgrip strength and loneliness.
