The purpose of this study was to test the ability of Corah's Dental Anxiety Scale (DAS) and Spielberger's State Anxiety Inventory (STAI-S) to distinguish between fearful (n = 145) and regularly attending (n = 156) Norwegian dental patients. The reliability of both instruments was high (Cronbach's alpha indices > 0.95). With DAS, 90% of the fearful patients and 85% of the reference patients were correctly assigned to their appropriate group. Thus it may be concluded that, when used on a Norwegian population, DAS is a valid instrument for distinguishing fearful patients from those regularly attending dental treatment. The corresponding figures for STAI-S were 80% for the fearful patients and 79% for the reference patients. Although not developed specifically for this purpose, this instrument may therefore still validly be used to distinguish between the groups. The correlation between the instruments was 0.76, indicating that to some extent they measure the same phenomenon.
The link between physical activity (PA) and prevention of disease, maintenance of independence, and improved quality of life in older adults is supported by strong evidence. However, there is a lack of data on population levels in this regard, where PA level has been measured objectively. The main aims were therefore to assess the level of accelerometer-determined PA and to examine its associations with self-reported health in a population of Norwegian older adults (65-85 years).
This was a part of a national multicenter study. Participants for the initial study were randomly selected from the national population registry, and the current study included those of the initial sample aged 65-85 years. The ActiGraph GT1M accelerometer was used to measure PA for seven consecutive days. A questionnaire was used to register self-reported health. Univariate analysis of variance with Bonferroni adjustments were used for comparisons between multiple groups.
A total of 560 participants had valid activity registrations. Mean age (SD) was 71.8 (5.6) years for women (n=282) and 71.7 (5.2) years for men (n=278). Overall PA level (cpm) differed considerably between the age groups where the oldest (80-85 y) displayed a 50% lower activity level compared to the youngest (65-70 y). No sex differences were observed in overall PA within each age group. Significantly more men spent time being sedentary (65-69 and 70-74 years) and achieved more minutes of moderate to vigorous PA (MVPA) (75-79 years) compared to women. Significantly more women (except for the oldest), spent more minutes of low-intensity PA compared to men. PA differed across levels of self-reported health and a 51% higher overall PA level was registered in those, with "very good health" compared to those with "poor/very poor health".
Norwegian older adults PA levels differed by age. Overall, the elderly spent 66% of their time being sedentary and only 3% in MVPA. Twenty one percent of the participants fulfilled the current Norwegian PA recommendations. Overall PA levels were associated with self-reported health.
To evaluate the accessibility and distribution of the Norwegian National Air Emergency Service in the 10-year period from 1988 to 1998.
The primary material was annual standardized activity data that included all helicopter missions. A multivariate model of determinants for use of the helicopter service was computed by linear regression. Accessibility was measured as the percentage of the population reached in different flying times, and we evaluated the service using a simulation of alternative locations for the helicopter bases.
The helicopter service (HEMS) has short access times, with a mean reaction time of 8 minutes and a mean response time of 26 minutes for acute missions. Nearly all patients (98%) are reached within 1 hour. A simulation that tested alternative locations of the helicopter bases compared with current locations showed no increase in accessibility. The use of the service shows large regional differences. Multivariate analyses showed that the distances of the patients from the nearest helicopter base and the nearest hospital are significant determinants for the use of HEMS.
Establishment of a national service has given the Norwegian population better access to highly qualified prehospital emergency services. Furthermore, the HEMS has a compensating effect in adjusting for differences in traveling distances to a hospital. Safety, cost-containment, and gatekeeper functions remain challenges.
The objective was to describe the psychosocial burden experienced by informal carers of elderly stroke victims, and to identify its predictors among baseline characteristics of the patients. From a prospective study of 171 elderly stroke patients admitted to a geriatric ward for rehabilitation in the acute phase, 68 patients living at home with a primary caregiver were identified 6 months after the stroke. At baseline, all the patients were assessed with respect to motor function, cognitive function, global handicap and activities of daily living, and after 6 months the caregivers were assessed, using the Relatives' Stress Scale. According to this, the most frequent impacts were worries that an accident might befall their relatives, that they had to reorganise their household routines and further, that their social life and ability to take holidays had been reduced. Impaired cognitive function was the only baseline patient characteristic that predicted a subsequent psychosocial burden on the carer. Special attention should be paid to elderly stroke patients initially assessed with impaired cognitive function and their caregivers.
The aim of the present study was to explore contextual and individual factors associated with acute stress reactions in three Norwegian submarine crews exposed to different significant peacetime maneuver accidents. Approximately 2 to 3 weeks after the accidents, crew members completed the Coping Style Questionnaire, the General Health Questionnaire, the Impact of Event Scale, and the Post-Traumatic Symptom Scale. Although exposed subjects (N = 47) revealed more posttraumatic stress symptoms than nonexposed crew members on shore leave (N = 7), they showed less acute stress reactions than survivors from a surface ship accident in the Norwegian Navy. Inspection of individual cases revealed that 4% of the exposed submariners showed high loads of acute stress symptoms. Unit cohesion and habitual coping styles emerged as resilience factors, whereas previous exposure to critical incidents and personal experience of not coping in the accident situation emerged as vulnerability factors, explaining 32% of the acute stress reactions reported by submarine crew members.
Several healthy dietary patterns have been linked to longevity. Recently, a Nordic dietary pattern was associated with a lower overall mortality. No study has, however, investigated this dietary pattern in relation to cause-specific mortality. The aim of the present study was to examine the association between adherence to a healthy Nordic food index (consisting of wholegrain bread, oatmeal, apples/pears, root vegetables, cabbages and fish/shellfish) and overall mortality, and death by cardiovascular disease, cancer, injuries/suicide and other causes. We conducted a prospective analysis in the Swedish Women's Lifestyle and Health cohort, including 44,961 women, aged 29-49 years, who completed a food frequency questionnaire between 1991-1992, and have been followed up for mortality ever since, through Swedish registries. The median follow-up time is 21.3 years, and mortality rate ratios (MRR) were calculated using Cox Proportional Hazards Models. Compared to women with the lowest index score (0-1 points), those with the highest score (4-6 points) had an 18% lower overall mortality (MRR 0.82; 0.71-0.93, p
The purpose of this study was to describe levels of inflammation markers in Norwegian children and to examine the associations of adiposity, aerobic fitness, and muscle fitness with markers of inflammation.
In 2005-2006, 1467 nine-year-olds were randomly selected from all regions in Norway. The participation rate was 89%. The inflammatory markers evaluated included C-reactive protein (CRP), leptin, adiponectin, plasminogen activator inhibitor-1, tumor necrosis factor-a, hepatocyte growth factor, resistin, and interleukin-6. We assessed muscular strength by measuring explosive, isometric, and endurance strength. Aerobic fitness was measured directly during a maximal cycle ergometer test. Adiposity was expressed as waist circumference (WC).
The girls had significantly higher levels of CRP, leptin, adiponectin, and resistin and lower levels of tumor necrosis factor-a compared with the boys. We observed a graded association of CRP and leptin levels across quintiles of WC, aerobic fitness, and muscle fitness (P = 0.001 for all participants). The regression analyses revealed that WC, aerobic fitness, and muscle fitness were independently associated with the CRP (WC ß = 0.158, P
In the present study, we evaluated whether childhood differences in body height between singletons and twins persist into adulthood. Data from the Medical Birth Register of Norway were linked with data from the Norwegian National Conscript Service. This study used data on the 457,999 males who were born alive and without physical anomalies in single or twin births in Norway during 1967-1984 and who were examined at the mandatory military conscription (age 18-20 years; 1985-2003). For sibling comparisons, the authors selected the 1,721 sibships of full brothers that included at least 1 male born in a single birth and at least 1 male born in a twin birth (4,520 persons, including 2,493 twins and 2,027 singletons). An analysis of the total study population using generalized estimating equations showed that the twins were 0.6 cm (95% confidence interval: 0.4, 0.7) shorter than were the singletons after adjustment for a series of background factors. The fixed-effects regression analysis of the sibships that included both twins and singletons showed that the twins were 0.9 cm (95% confidence interval: 0.6, 1.2) shorter than were their singleton brothers. The study suggests that male twins born in Norway during 1967-1984 were slightly shorter in early adulthood than were singletons.
Age at first intercourse among Norwegian adolescents was studied by means of survival analysis. The data stemmed from a nation-wide survey of 3000 Norwegian adolescents aged 17-19, yielding a response rate of 61.8%. Median age at first intercourse was 17.3 years among girls and 18.0 years among boys. By means of Cox regression analysis associations between age at onset of intercourse and some correlates were estimated. Age at first intercourse was significantly associated with educational aspirations, smoking behaviour, alcohol consumption, peer affiliation, and frequency of visiting a discotheque. These inter-relationships confirm that age at onset of intercourse comprise an important indicator of the lifestyle of an individual. In order to influence sexual behaviour of adolescents it may thus be appropriate to employ health promotion activities focusing upon environmental and structural factors, as a supplement to traditional methods of sex education.
Socioemotional risks associated with nonparental care have been debated for decades, and research findings continue to be mixed. Yet few studies have been able to test the causal hypothesis that earlier, more extensive, and longer durations of nonmaternal care lead to more problems. To examine the consequences of age of entry into nonparental care for childhood aggression, we used prospective longitudinal data from Norway, where month of birth partly determines age of entry into Early Childhood Education and Care (ECEC) centers. In this sample of 939 children followed from ages 6 months through 4 years, ECEC teachers reported the children's aggression when they were 2, 3, and 4 years old. We found some evidence that age of entry into ECEC predicted aggression at age 2, albeit modestly and not robustly. Between the ages of 2 and 4 years, the effect of age of entry on aggression faded to negligible levels. The implications for psychological science and policy are discussed.
