The aims of this study were first to investigate, by means of a mail questionnaire, variables from three domains: (i) socio-economic attributes; (ii) general and oral health; and (iii) dental attitudes and behaviours in a large sample of 50- and 60-year-old subjects, and second to compare subjects with or without reported temporomandibular joint (TMJ) pain with respect to these variables. In 2002, a questionnaire was mailed to all 50- and 60-year-old subjects in two Swedish counties, Orebro and Ostergötland (n = 17,138; n50 = 8878; n60 = 8260). Individuals not responding within 2 weeks were given a reminder. If still not answering, a new questionnaire was sent. The final response rate was 72.8% (n = 12,468). The reported responses to questions regarding 'pain in the TMJ region' and 'difficulty to open the mouth wide' were dichotomized into two groups: (i) no temporomandibular disorders (TMD) symptoms; and (ii) some, rather great or severe TMD symptoms. Striking differences in demographic, occupational, general and oral health conditions were found between the groups with and without TMD symptoms. The strongest risk indicator for both pain and dysfunction was reported bruxism. Women, younger subjects (50 years old) and blue-collar workers were significantly more prevalent in the TMD symptom groups. Variables related to impaired general and oral health were more common in the groups with reported TMD problems, whereas satisfaction with received dental care and with teeth was lower. Individuals with reported TMD symptoms differed significantly from those without TMD symptoms in socio-economic attributes, general and oral health symptoms, dental conditions and satisfaction with their teeth.
In 1992 a questionnaire was sent to 50-year-olds in two Swedish counties. These self-report data were compared with clinical observations with regard to number of teeth, removable dentures, caries, and periodontitis. Complete information from both data sources was obtained for 1041 persons. The relevant questionnaire item explained 71% of the missing tooth variance. An agreement of 0.91 (Cohen's kappa) was obtained for removable dentures. A question about problems in opening the mouth differentiated clearly with regard to measured mouth opening ability. Toothache and tooth sensitivity were reported with 95% probability when having 22 decayed teeth and with 46% when there were no decayed teeth (58% correctly predicted). Two teeth with pockets > or = 6 mm gave 5% probability and 22 such teeth gave 39% probability of reporting migration of front teeth. The main conclusion from this study is that there is good correspondence between subjective self-reports and clinical findings, especially for those conditions that are relatively easy for the patient to observe, such as the number of teeth and the presence of dentures. Thus questionnaire data can be used for information and screening about some well-defined oral conditions.
A cross-sectional dental questionnaire census survey was conducted in classrooms of 17,280 students aged 13-18 years in Skaraborg County, Sweden. The overall response rate, based on school attendance on the test day, was 91% with no gender differences at the senior level, and 86% (boys 87%, girls 85%) at the upper secondary level. The aim was to examine gender differences in knowledge, attitude, behavior and perceived oral health. A retest study showed good agreement. Thirty-one percent of the girls and 21% of the boys flossed regularly. Eleven percent reported daily candy consumption, with no significant gender difference. Girls, however, more often than boys considered their own consumption to be too high. This gender difference in attitude was most pronounced among older daily consumers (odds ratio (OR) = 5.8 [3.7-9.2]). Oral health was regarded as important by a majority of the students (95%). Girls considered sound teeth to be more important than did boys, both among the younger (OR = 1.7 [1.4-2.1]) and the older (OR = 2.4 [1.9-3.1]) adolescents. It is concluded that most adolescents had a positive dental attitude and perceived their own oral health to be good. Poorer knowledge and behaviors concerning oral health were demonstrated. Gender differences existed in most issues. Girls scored more favorably on behavioral measures, showed more interest in oral health, and perceived their own oral health to be good to a higher degree than did boys.
BackgroundRisk factors for hip fracture are well studied because of the negative impact on patients and the community, with mortality in the first year being almost 30% in the elderly. Age, gender and fall risk-increasing drugs, identified by the National Board of Health and Welfare in Sweden, are well known risk factors for hip fracture, but how multimorbidity level affects the risk of hip fracture during use of fall risk-increasing drugs is to our knowledge not as well studied. This study explored the relationship between use of fall risk-increasing drugs in combination with multimorbidity level and risk of hip fracture in an elderly population.MethodsData were from Östergötland County, Sweden, and comprised the total population in the county aged 75 years and older during 2006. The odds ratio (OR) for hip fracture during use of fall risk-increasing drugs was calculated by multivariate logistic regression, adjusted for age, gender and individual multimorbidity level. Multimorbidity level was estimated with the Johns Hopkins ACG Case-Mix System and grouped into six Resource Utilization Bands (RUBs 0–5).Results2.07% of the study population (N = 38,407) had a hip fracture during 2007. Patients using opioids (OR 1.56, 95% CI 1.34-1.82), dopaminergic agents (OR 1.78, 95% CI 1.24-2.55), anxiolytics (OR 1.31, 95% CI 1.11-1.54), antidepressants (OR 1.66, 95% CI 1.42-1.95) or hypnotics/sedatives (OR 1.31, 95% CI 1.13-1.52) had increased ORs for hip fracture after adjustment for age, gender and multimorbidity level. Vasodilators used in cardiac diseases, antihypertensive agents, diuretics, beta-blocking agents, calcium channel blockers and renin-angiotensin system inhibitors were not associated with an increased OR for hip fracture after adjustment for age, gender and multimorbidity level.ConclusionsUse of fall risk-increasing drugs such as opioids, dopaminergic agents, anxiolytics, antidepressants and hypnotics/sedatives increases the risk of hip fracture after adjustment for age, gender and multimorbidity level. Fall risk-increasing drugs, high age, female gender and multimorbidity level, can be used to identify high-risk patients who could benefit from a medication review to reduce the risk of hip fracture.
Osteopenia/osteoporosis affect many elderly people and might not be detected until symptoms of fractures occur. Early detection of osteopenia/osteoporosis is important and would allow preventive measures and treatment. Access to screening for osteopenia/osteoporosis is often limited, whereas panoramic radiography is commonly used in dentistry. The aim of this study was to determine the validity of the Klemetti index (KI), measured on panoramic radiographs, in the diagnosis of osteopenia/osteoporosis as defined by a bone mineral density (BMD) measurement below -1.5 standard deviations (SDs) of a community based sample. In total, 211 consecutive participants (102 men and 109 women) 60-96 years in the SNAC-Blekinge study (Swedish National Study on Ageing and Care) underwent bone densitometry [by dual-energy X-ray absorptiometry (DXA)] of both heels. A panoramic radiograph was taken of each participant, and mandibular cortex on a panoramic radiograph was classified as '0' or normal (even and sharp endosteal margin), '1', moderately eroded (evidence of lacunar resorption or endosteal cortical residues), or '2', severely eroded (unequivocal porosity). From logistic regression, the odds ratio of having a BMD measurement below -1.5 SD was 8.04 (95% CI 2.39 to 27.12, P<0.001) in the 'osteopenic' (KI category 2), compared with the 'normal' group (KI categories 0 and 1). Receiver operating characteristic (ROC) curve analysis was used to measure the validity of the KI indicating osteopenia (KI category 2) in predicting reduced BMD. This point provided a sensitivity of 50% and a specificity of 89%. Positive and negative predictive values were 21% and 97%, respectively. There were 87% correctly classified subjects. The area under the ROC curve was 0.64. The present study demonstrated that a negative finding (KI category <2) is highly predictive of the absence of osteopenia/osteoporosis as defined by the DXA measurements.
Accounts of self-perceptions of oral health have hitherto been rare, although they are of great interest for strategies in health promotion. The objective of this study was to increase our knowledge of adolescents' perceptions of oral health and influencing factors. Semi-structured interviews of 17 Swedish adolescents were performed. Criteria for strategic sampling were age (15, 18 years), gender (male, female), and dental health (healthy, unhealthy). Data were analyzed according to the constant comparative method. Areas of focus were general oral health, personal oral health, dental care, and life-style issues. Oral health awareness was generally low among the informants. Two categories of oral health were identified: action (the physical things we do to effect the condition of our mouths) and condition (the physical status of the mouth). Conditional aspects were most frequent in evaluations of personal oral health. The informants considered their possibilities to influence oral health limited. Perceptions of influences on oral health were related to personal and professional care, social support and impact, and external factors. 'Concern for oral health' was derived as the core category in perceived influence on oral health. The study indicates that it is important to find factors that enhance adolescents' awareness of their own resources and to seek mechanisms that govern internalization. There is a need to find strategies to convey such knowledge to the intermediaries: dental personnel and parents.
The aim of the present study was to investigate the long-term incidence rate of Lyme borreliosis and, additionally, to determine whether a correlation exists between climatic factors and summer-season variations in the incidence of Lyme borreliosis. Climatic variability acts directly on tick population dynamics and indirectly on human exposure to Lyme borreliosis spirochetes. In this study, conducted in primary healthcare clinics in southeastern Sweden, electronic patient records from 1997-2003 were searched for those that fulfilled the criteria for erythema migrans. Using a multilevel Poisson regression model, the influence of various climatic factors on the summer-season variations in the incidence of erythema migrans were studied. The mean annual incidence rate was 464 cases of erythema migrans per 100,000 inhabitants. The incidence was significantly higher in women than in men, 505 and 423 cases per 100,000 inhabitants, respectively (p<0.001). The summer-season variations in the erythema migrans incidence rate correlated with the monthly mean summer temperatures (incidence rate ratio 1.12; p<0.001), the number of winter days with temperatures below 0 degrees C (incidence rate ratio 0.97; p<0.001), the monthly mean summer precipitation (incidence rate ratio 0.92; p<0.05), and the number of summer days with relative humidity above 86% (incidence rate ratio 1.04; p<0.05). In conclusion, Lyme borreliosis is highly endemic in southeastern Sweden. The climate in this area, which is favourable not only for human tick exposure but also for the abundance of host-seeking ticks, influences the summer-season variations in the incidence of Lyme borreliosis.
This study investigated the relationship between light and strenuous exercise and depression, as well as gender differences in this relationship, in a representative sample of 860 elderly Swedish suburb-dwelling men and women in age cohorts from 60 to 96 years, drawn from among participants in the Swedish National Aging and Care study. The relationship between depression and self-reported changes in exercise status over time was also examined. Exercise activities were measured with four survey questions, and depression, with the Montgomery Asberg Depression Rating Scale. The inactive elderly had higher depression scores than more active individuals, both in terms of light and strenuous exercise. The continuously active group had lower depression scores than both continuously inactive individuals and individuals reporting a shift from activity to inactivity during the preceding year. Light exercise had a somewhat stronger effect on depression for women.
