- BACKGROUND: Older people in rural areas have been labelled as physically inactive on the basis of leisure-time physical activity research. However, more research is needed to understand the total physical activity pattern in older adults, considering all domains of physical activity, including leisure, work, and domestic life. AIMS: We hypothesised that: (a) total physical activity would be the same for older people in urban and rural areas; and (b) urban and rural residency, along with gender and age, would be associated with differences in domain-specific physical activities. METHODS: Cross-sectional data were collected in Icelandic rural and urban communities from June through to September 2004. Participants were randomly selected, community-dwelling, 65-88 years old, and comprised 68 rural (40% females) and 118 urban (53% females) adults. The Physical Activity Scale for the Elderly (PASE) was used to obtain a total physical activity score and subscores in leisure, during domestic life, and at work. RESULTS: The total PASE score was not associated with rural vs. urban residency, but males were, in total, more physically active than females, and the 65-74-year-olds were more active than the 75-88-year-olds. In the leisure domain, rural people had lower physical activity scores than urban people. Rural males were, however, most likely of all to be physically active in the work domain. In both urban and rural areas, the majority of the physical activity behaviour occurred in relation to housework, with the rural females receiving the highest scores. CONCLUSIONS: Older Icelanders in rural areas should not be labelled as less physically active than those who live in urban areas. Urban vs. rural living may, however, influence the physical activity patterns among older people, even within a fairly socioeconomically and culturally homogeneous country such as Iceland. This reinforces the need to pay closer attention to the living environment when studying and developing strategies to promote physical activity.

- People with dementia have an increased risk of falling. Predisposing factors explain only a small part of the variation in falls among people with dementia. The purpose of this study was to explore circumstances that are hazardous regarding falls among people with dementia at a psychogeriatric ward. The study comprised 191 participants of whom seventy-five fell a total of 229 times. Prospective data were collected on falls. Hazardous circumstances were calculated in two ways. Firstly possible differences between day/night falls and women/men falls were calculated based on the 229 falls. Secondly time to first fall was used to estimate hazardous circumstances and was based on 75 falls. This study shows a fall rate that was equally high during the night and the day. The proportion of diurnal rhythm disturbances and activity disturbances was higher for falls at night than for falls during the day. Circumstances associated with an increased risk of falls, as shown by a short time to first fall, were anxiety, darkness, not wearing any shoes and, for women, urinary tract infection. All of these are circumstances that should be considered in future fall-related research among people with dementia.

Tidskriftsartikel (refereegranskat)abstract
- Searching for background factors associated with falls in people with dementia is difficult because the population is heterogeneous. The aim of this study was to compare the efficacies of three statistical methods for analysis of fall predictors in people with dementia. NBR, RT and PLSR analyses were compared. Data used for the comparison were from a prospective cohort study of 192 patients at a psychogeriatric ward, specializing in patients with cognitive impairment and related behavioral and psychological symptoms. Seventy-eight of these patients fell a total of 238 times. PLSR and RT analyses are directed at finding patterns among predictor variables related to outcome, whereas an NBR model is directed at finding predictor variables that, independent of other variables, are related to the outcome. The NBR analysis explained an additional 10–15% variation compared with the PLSR and RT analyses. The results of PLSR and RT show a similar plausible pattern of predictor variables. However, none of these techniques appears to be sufficient in itself. In order to gain patterns of explanatory variables, RT would be a good complement to NBR for analysis of fall predictors.

Falls in people with dementia
- 2007

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Falls and concomitant injuries are common problems among large groups of the elderly population, leading to immobility and mortality. These problems are even more pronounced among people suffering from dementia. This thesis targets fall risk factors for people with dementia in institutions. The overall aim of this thesis was to investigate risk factors for falls, predisposing as well as related to circumstances surrounding falls, and to do this as efficiently as possible. In a prospective cohort study including residents of residential care facilities with and without dementia, the fall rate was higher for those with dementia, the crude incidence rate ratio (IRR) was 2.55 (95% CI 1.60–4.08) and the adjusted IRR was 3.79 (95% CI 1.95–7.36). In the group of people suffering from dementia, including 103 residents, a total of 197 falls resulted in 11 fractures during the 6-months follow-up period. From the same baseline measurements 26% and 55%, respectively, of the variation in falls could be explained in the group of residents with and without dementia. Fall predictors significantly and independently associated with an increased risk of falls in the group of people suffering from dementia were the category “man walking with an aid” and the use of more than four drugs. In a prospective cohort study, including 204 patients in a psychogeriatric ward, a total of 244 falls resulted in 14 fractures. Fall predictors significantly and independently associated with an increased risk of falls were male sex, failure to copy a design, use of clomethiazole, and walking difficulties. Treatment with statins was associated with a reduced risk of falls. With these fall predictors in the negative binomial regression (Nbreg) model, 48% of the variation in falls was explained. The data from the psychogeriatric ward were also analysed with the use of partial least squares regression (PLS) and regression tree to be compared with the results of the Nbreg analysis. PLS and regression tree are techniques based on combinations of variables. They both showed similar patterns, that a combination of a more severe level of dementia, behavioral complications and medication related to these complications is associated with an increased fall rate. Thirty-two percent and 38%, respectively, of the variation in fall rate were explained in the PLS and regression tree analysis. The circumstances surrounding the falls in the psychogeriatric ward were analysed. It was found that the fall rate was equally high during the night and the day. A large proportion of the falls was sustained in the patients’ own room and a small proportion of the falls was witnessed by the staff. This pattern was even more pronounced during the night. The proportion of diurnal rhythm disturbances and activity disturbances was higher for falls at night than for falls during the day. Circumstances associated with an increased risk of falls, as shown by a short time to first fall, were anxiety, darkness, not wearing any shoes and, for women, urinary tract infection. The proportion of urinary tract infection was also higher in connection to falls sustained by women than to falls sustained by men. This thesis confirms that people suffering from dementia are prone to fall. Walking difficulties, male sex and impaired visual perception are factors that should be considered in the work of reducing falls among people suffering from dementia. Furthermore, falls at night, behavioral complications and medication related to these complications should also be considered in this work, especially as the dementia disease progresses. A larger portion of the variation of the outcome variable was explained by the Nbreg model than the regression tree and PLS. However, these statistical methods, based on combinations of variables, gave a complementary perspective on how the fall predictors were related to falls.

- People with dementia are at increased risk of falling. The purpose of this study was to identify predisposing risk factors for falls in older people with and without a diagnose of dementia living in residential care facilities, and to compare the results. Eighty-three residents without dementia (mean age ± S.D.; 83.5 ± 7.1 years) and 103 with dementia (83.6 ± 6.3 years) in Umeå, Sweden, participated. The baseline assessment included probable risk factors like walking ability, diagnoses and treatment with drugs. The follow-up period was 6 months. In people with dementia, the fall rate was higher (crude incidence rate ratio 2.55, 95% CI 1.60–4.08) and a larger proportion experienced falls (62% versus 41%). In the group without dementia 54.8% of the variation in falls was explained by a model including orthostatism, “women walking with aid”, and treatment with Angiotensin Converting Enzyme (ACE) inhibitors. In the group with dementia 25.5% of the variation in falls was explained by a model including “man walking with aid”. Our results show that with the same set of common risk factors for falls a considerably lower proportion of the variation in falls can be explained in the group of people with dementia.

Motivationsekvationen : att vägleda äldre personer till fysisk aktivitet
- 2008

Ingår i: Fysioterapi. ; :5, s. 38-45

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Det finns ett tydligt samband mellan ökad ålder och minskande fysisk aktivitet, trots att aktiviteten ger hälsovinster för äldre personer på alla funktionsnivåer. Många äldre har kontakt med hälso- och sjukvården, vilket ger personalen en ypperlig möjlighet att påverka dem. För att vägleda äldre personer till fysisk aktivitet gäller det att finna faktorer som ökar motivationen och att identifiera barriärer. Motivationsekvationen, som presenteras här, är en modell som belyser sambandet mellan fyra faktorer: ”upplevd chans att lyckas” och ”upplevd betydelse av målet” i förhållande till ”upplevd kostnad” och ”benägenhet att bli stillasittande”. Samspelet mellan dem styr våra medvetna och omedvetna val när det gäller att påbörja och bibehålla olika beteenden. Faktorerna kan påverkas, direkt eller indirekt, och genom att öka de båda förstnämnda och minska de båda senare skapas hög motivation. Motivationsekvationen kan användas för att kartlägga patientens motivationsnivå. Tillsammans med det vägledande samtalet ger den möjlighet till individuellt skräddarsydda åtgärder.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND AND AIMS: Identification of the risk of falls in a cohort of interest is a prerequisite for a targeted fall prevention study. Motor tasks are widely used as baseline assessment in such studies, but there are only a few well-evaluated tests of motor performance to predict falls prospectively. This study was conducted to find out if the potential of the maximum step length (MSL) test can predict future falls in non-disabled older persons. METHODS: A modified version of the MSL test was used for baseline assessment in 56 community-dwelling, non-disabled elderly persons (mean age 67.7 yrs, SD 6 yrs; 57% women). During a follow-up of 1 year, falls were recorded in a daily calendar. RESULTS: During the follow-up, 30 persons (54%) fell, with no gender difference in reporting of falls between men and women. The adjusted mean valid step length and adjusted maximum valid step length were predictive of future falls with a sensitivity/specificity of 77%/62% and 70%/69%, respectively. Combining MSL test results with fall history increased sensitivity to 93% and 90%, respectively, but decreased specificity to 54% and 58%, respectively. CONCLUSIONS: The MSL test is a feasible tool, with low requirements in space, predicting future falls in community-dwelling older persons. In combination with history of falls, the sensitivity of the test increased considerably.
