Frequency and factors associated with falls in adults aged 55 years or more

Resumen

OBJECTIVE The objective of this study is to analyze the frequency and factors associated with falls in adults aged 55 years or more. METHODS This is a study inserted into another population-based study with representative sample of persons aged 40 years or more of the urban area in a medium-sized municipality of the State of Paraná, Brazil, in 2011. That study obtained demographic and socioeconomic data and characteristics related to life habits, health conditions, and functional capacity (n = 1,180). In 2012, we selected all persons aged 55 years or more (n = 501). We have estimated grip strength and the occurrence of a fall since the last interview in 80.6% of the adults. The crude and adjusted odds ratios (OR) have been calculated by logistic regression according to a hierarchical model. RESULTS The rate of fall was 24.3%. After adjustments, we could observe higher chances of falls among women (OR = 3.10; 95%CI 1.79–5.38), among persons aged 65 years or more (OR = 2.39; 95%CI 1.45–3.95), with poor sleep quality (OR = 1.78; 95%CI 1.08–2.93), and with low grip strength (OR = 2.31; 95%CI 1.34–3.97). CONCLUSIONS Poor sleep quality and low muscle strength can be indicators of increased risk of falls and need assessments and interventions aimed at preventing them.
