Health risk appraisal in older people 7: long-acting benzodiazepine use in community-dwelling older adults in London: is it related to physical or psychological factors?

Aim To investigate whether the use of long-acting benzodiazepines, in individuals aged 65 and over is mediated by physical or psychological factors. BACKGROUND: Long-acting benzodiazepine consumption among older people has implications for mortality, morbidity and cost-effective prescribing. Two models explain benzodiazepine use in this age group, one linked to physical illness and disability and one to psychological factors. METHODS: Secondary analysis of baseline data from a study of 1059 community-dwelling non-disabled people aged 65 years and over recruited from three general practices in London. For this analysis, use of long-acting benzodiazepines was defined as any self-reported use of diazepam or nitrazepam in the last four weeks. Associations between demographic factors, health service use, and physical and psychological characteristics and benzodiazepine use were investigated. Findings The prevalence of benzodiazepine use in this sample was 3.3% (35/1059). In univariate analyses, benzodiazepine use was associated with female gender, low income, high consultation rates, physical factors (medication for arthritis or joint pain, polypharmacy, difficulties in instrumental activities of daily living, recent pain) and psychological factors (poor self-perceived health, social isolation, and symptoms of anxiety or agitation). In a multivariate logistic regression analysis only two factors retained statistically significant independent associations with benzodiazepine use: receiving only the state pension (OR=4.0, 95% CI: 1.70, 9.80) and pain in the past four weeks (OR=3.79, 95% CI: 1.36, 10.54).

The impact of educational level on oral health-related quality of life in older people in London.

There are socioeconomic inequalities in oral health, but the relationship between education and oral health-related quality of life (OHRQoL) among older adults has not been adequately studied. This study assessed whether there is an educational gradient in OHRQoL among older people in London. We employed secondary analysis of baseline data (n = 1,090) from a randomized controlled trial of health-risk appraisal on community-dwelling non-disabled people 65 yr of age and older, registered with three group medical practices in suburban London. Multiple linear regressions were used to analyze the association between OHRQoL [measured using the Geriatric Oral Health Assessment Index (GOHAI)] and education, adjusted for age, gender, pension status, and denture wearing. Overall, 30.6% reported low levels of OHRQoL. Eating discomfort was the most frequent problem (24% reported 'often/always'), while concerns about appearance were also prevalent. Significant variations in OHRQoL existed between socioeconomic groups. In adjusted analyses, there was a clear education gradient in OHRQoL, with worse perceptions at each lower level of education. Low educational level has an independent negative impact on OHRQoL in older people, which is not explained by differences in income or in denture wearing between educational groups. Policies targeting lower educated groups should be complemented with whole-population strategies for the reduction of oral health inequalities.

The relationship between pain intensity and severity and depression in older people: exploratory study.

BACKGROUND: Pain and depression are known to be associated in later life, and both have a negative effect on physical performance both separately and in combination. The nature of the relationships between pain intensity and depression in elderly persons experiencing pain is less clear. The objectives of this study were to explore which factors are associated with depressed mood in older people experiencing pain, and to test the hypothesis that older people experiencing pain are at risk of depressed mood according to the severity or frequency of their pain. In addition we explored whether other potentially modifiable factors might increase the risk of depressed mood in these persons. METHODS: The study is a secondary analysis of baseline data for four hundred and six community-dwelling non-disabled people aged 65 and over registered with three group practices in suburban London who had experienced pain in the past 4 weeks. Intensity and frequency of pain was measured using 24 item Geriatric Pain Measure (GPM) and the presence of depressive symptoms using the 5 item Mental Health Inventory. Risk for social isolation was measured using the 6 item Lubben Social Network scale and instrumental activities of daily living (IADL) were also measured. RESULTS: Overall 76 (19%) had depressed mood. Pain frequency and severity were not statistically significantly associated with depressed mood in this population. In multivariate analyses, significant predictors of the presence of depressive symptoms were difficulties with basic ADLs (OR 2.8, 95% CI 1.1.7.8), risk for social isolation (OR 4.1, 95% CI 1.8-9.3), and basic education only (OR 2.2, 95% CI 1.1-4.4). CONCLUSION: Older people experiencing pain are also likely to experience depression. Among those experiencing pain, social network and functional status seem to be more important predictors of depressive symptoms than the severity of pain. Further studies should evaluate whether improvement of social network and functional status might reduce depressive symptoms in older patients.
