Predictors and Incidence of Urinary Incontinence in Elderly Canadians With and Without Dementia — A Five-Year Follow Up: The Canadian Study of Health and Aging

A scoping review of risk factors for urinary incontinence in older men

BACKGROUND

Most epidemiological studies have not systematically identified or categorized risk factors for urinary incontinence (UI) in older men, despite a higher prevalence than in younger men. Considering the burden of UI, an understanding of risk factors can inform cost-effective prevention/treatment programs. This scoping review aimed to identify and categorise risk factors for UI in older men, identify gaps in the evidence, and opportunities for future research.

METHODS

The Joanna Briggs Institute (JBI) method for scoping reviews guided the conduct and reporting of this review alongside the Preferred Reporting Items for Systematic Reviews and Meta-analyses extension for scoping reviews checklist. JBI's Population, Concept, and Context approach framed the inclusion criteria (all evidence sources on UI risk factors that included older men [65 +]). We employed JBI's three-step search strategy, which included a limited initial search in Ovid MEDLINE, a detailed comprehensive database search, and a search of reference lists of included studies, Google Scholar and grey literature. There were no restrictions on language, study type, or publication date. Two independent reviewers screened, selected, and extracted eligible studies. Data were analyzed using descriptive statistics and qualitative content analysis.

RESULTS

Forty-seven articles that met the inclusion criteria identified 98 risk factors across six categories. Behavioural risk factors, reported by only two studies, were the least investigated of all the categories, whereas medical factors/diseases were the most investigated. No genetic factors were documented. The top five risk factors were increasing age/advanced age (n = 12), Benign Prostatic Hyperplasia (n = 11), Diabetes Mellitus (n = 11), Detrusor overactivity (n = 10), limitation in physical function/ADL disability (n = 10), increased Body Mass Index (BMI)/overweight/obesity (n = 8), Dementia (n = 8), and Parkinson's disease (n = 7).

CONCLUSION

There is a dearth of evidence to describe the role behavioural risk factors have in UI in older men. These factors may play a role in health promotion and disease prevention in this area.

A protocol detailing the methods was developed and published, and is registered in the Open Science Framework [Feb 07 2023; https://osf.io/xsrge/ ].

A conceptual model of the risk of elder abuse posed by incontinence and care dependence

AIMS AND OBJECTIVES

To describe and critically analyse the thinking that led to the concept of an association between incontinence, care dependence and elder abuse.

BACKGROUND

Coercive or abusive continence care practices include chastising a person for their incontinence and overriding their attempts to resist continence care. Neglect in continence care is characterised by withholding or delaying responding to requests for help to maintain continence or to manage incontinence, and restricting a person's access to toileting assistance, incontinence aids or hygiene care.

METHODS

Contemporary biomedical understandings about incontinence and influencing concepts from the fields of sociology, psychology and nursing were analysed to inform the design of a conceptual model that elucidates possible associations between incontinence, care dependence and elder abuse.

RESULTS

Ideas generated from an analysis of the concepts led to the development of a model termed the "Model of Attributes to Abuse of Dependent Elders in Continence Care" (MADE-CC). The MADE-CC theorises factors that cause and contribute to abuse in continence care. Carer factors include physical and emotional exhaustion, frustration related to the inability to control or predict incontinence, resentment associated with constraints imposed by care dependence, disgust associated with physical contact with urine/faeces, limited knowledge and skills about incontinence and ethical conflicts concerning care. Care recipient factors include frequent and severe incontinence, cognitive impairment and a history of physical or psychological trauma. Social factors that are theorised include the stigmatised nature of incontinence, social taboos and cultural norms and the private nature of continence care.

CONCLUSIONS

The MADE-CC illuminates the potential risk of elder abuse posed by incontinence and care dependence. It should be used to improve ethical care of older people and stimulate debate about everyday ethics in the care of older people who are care dependent and to optimise their participation in decisions about their health and well-being.

IMPLICATIONS FOR PRACTICE

Nurses and carers should be aware of the multiple interrelated factors that contribute to the risk of elder abuse in the caregiving encounter, including the role of emotions.

The Role of Social Support in the Relationship between Urinary Incontinence and Psychological Distress in Older Adults

While an association between UI and psychological distress among older adults has been established in the literature, the mechanisms underlying this relationship remain less clear. Using a sample of 4,689 older adults from the Canadian Community Health Survey (1.1), we test the potential mediating and moderating effects of four dimensions of social support on the UI–distress relationship. Incontinent older adults are significantly more likely to report higher levels of distress than continent adults. Although we do not find support for a mediating effect of any of the dimensions of social support, we do report a significant interaction between one dimension of social support (tangible support) and UI. A buffering effect of tangible support is evident for continent – but not incontinent – respondents. These findings emphasize the need to assess the types of social support and the context in which they operate.

A 10-year follow-up of urinary and fecal incontinence among the oldest old in the community: the Canadian Study of Health and Aging

Urinary incontinence is common in the elderly. The epidemiology of fecal and double (urinary and fecal) incontinence is less known. The Canadian Study of Health and Aging (CSHA) is a national study of elderly living in the community at baseline (n = 8,949) and interviewed in 1991-1992, 1996, and 2001. Using data from the CSHA, we report the prevalence of urinary, fecal, and double incontinence in each wave and the cumulative incidence between waves and investigate the predictors of urinary and fecal incontinence. Urinary incontinence increased rapidly in old age, being almost twice as high in women as in men. Fecal and double incontinence were less common, but also increased rapidly with age. In women, parity showed a positive relationship with (prevalent) urinary incontinence. In men, diabetes was a risk factor for urinary and fecal incontinence. We conclude that urinary, fecal, and double incontinence increase rapidly with age and that inquiry about incontinence should be part of routine medical and nursing assessment of all elderly.

More than the epidemiology of Alzheimer's disease: contributions of the Canadian Study of Health and Aging

OBJECTIVE

To highlight contributions to knowledge made by the Canadian Study of Health and Aging (CSHA).

METHOD

The CSHA began in 1991, with follow-ups in 1996 and 2001. It was national in scope, with 18 study centres and a coordinating centre. It included 10 263 participants; of these, 9008 were in the community, and 1255 were in institutions. In each phase, community participants were screened for cognitive impairment, and where appropriate, cognitive status was determined by a detailed clinical examination. Data on possible risk factors for dementia were collected at baseline. Data on caring for people with dementia were collected in each phase.

RESULTS

The prevalence of dementia was established at 8% of those aged 65 years and over; incidence (new cases each year) was about 2%. Cognitive impairment not dementia (CIND) was more than twice as common as dementia. Factors affecting the risk of institutionalization, mortality, and the health of caregivers were examined. The costs of dementia were conservatively estimated at dollar 3.9 billion in 1991. Risk factors for Alzheimer's disease (AD) and vascular dementia are presented; it is noteworthy that physical activity appeared to protect against all forms of cognitive decline, particularly for women. Clinical contributions include the development of norms for several neuropsychological tests. Other topics include the health of those with CIND, predicting dementia, medication use, frailty and healthy aging, and urinary incontinence.

CONCLUSION

The CSHA has contributed substantially to knowledge of the epidemiology of dementia, including AD, and to many other topics relevant to seniors' health.
