Gender differences in health care use among the elderly population in areas of Norway and Finland. A cross-sectional analysis based on the HUNT study and the FINRISK Senior Survey

BACKGROUND: The aim of the study was to examine gender differences in the self-reported use of health care services by the elderly in rural and metropolitan areas of two Nordic countries with slightly different health care systems: Finland and Norway. METHODS: Population based, cross-sectional surveys conducted in Nord-Tröndelag Norway (1995–97) and in rural and metropolitan areas of Finland (1997) were employed. In the Norwegian data, a total of 7,919 individuals, aged 65–74 years old were included, and the Finnish data included 1,500 individuals. The outcome variables comprised whether participants had visited a general practitioner or a specialist, or had received hospital care or physiotherapy during the past 12 months. Gender differences in the use of health care services were analysed by multiple logistic regression, controlling for health status and socio-demographic characteristics. RESULTS: In Norway, elderly women visited a specialist or were hospitalised less often than men. In Finland, elderly women used all health care services except hospital care more often than men. In Norway, less frequent use of specialist care by women was not associated with self-reported health or chronic diseases. CONCLUSION: The findings revealed differences in self-reported use of secondary care among different genders in areas of Norway and Finland

Fish Consumption and Omega-3 Polyunsaturated Fatty Acids in Relation to Depressive Episodes: A Cross-Sectional Analysis

High fish consumption and omega-3 polyunsaturated fatty acid (PUFA) intake are suggested to benefit mental well-being but the current evidence is conflicting. Our aim was to evaluate whether a higher level of fish consumption, a higher intake of omega-3 PUFAs, and a higher serum concentration of omega-3 PUFAs link to a lower 12-month prevalence of depressive episodes

Factors associated with signs of temporomandibular pain:an 11-year-follow-up study on Finnish adults

Abstract Background: Pain in the temporomandibular region is a main complaint causing disability and distress among temporomandibular disorders sufferers. Objectives: The aim of the study was, over an 11-year follow-up on Finnish adult population, to investigate the prevalence of clinically assessed pain-related temporomandibular disorder (TMD) signs, i.e. temporomandibular joint (TMJ) and masticatory muscles (MM) pain on palpation, and their association with sociodemographic background and denture status. Methods: The data were based on the nationally representative Finnish Health 2000 and Health 2011 Surveys (BRIF8901). The sample comprised 1210 adults who underwent clinical oral examinations including TMD signs assessment. Statistical evaluations included chi-square tests and logistic regressions. Results: The prevalence of palpatory MM pain decreased from 9.5% at baseline to 4.6% in the follow-up. Cross-sectionally, presence of palpatory MM pain significantly associated with gender (p < .001, p = .002) and educational level (p < .001, p = .001) in both years, and with age (p = .006) and denture status (p = .022) at baseline. The prevalence of palpatory TMJ pain increased from 2.1% at baseline to 3.5% in the follow-up. Presence of palpatory TMJ pain significantly associated with gender in both years (p = .012, p = .032). Female gender, lower education and palpatory MM pain at baseline predicted palpatory MM pain in the follow-up. Conclusion: Palpatory MM pain is relatively prevalent in adults, yet with a favourable prognosis. Women and people with low education are more susceptible groups. Previous experience of palpatory MM pain increases the risk of exhibiting it later in life

Association between cynical hostility and temporomandibular pain mediated through somatization and depression:an 11-year follow-up study on Finnish adults

Abstract Background: Hostility is believed to have an adverse effect on physical health through mediating psychosocial factors. Objectives: This study aimed to investigate the association of hostility with temporomandibular (TMD) pain. Another aim was to investigate if the association is mediated through increases in depressiveness and somatization in an 11-year follow-up on Finnish adults, based on the Health 2000 and 2011 Surveys (BRIF8901). Material and methods: The sample comprised subjects who underwent clinical TMD pain examination (pain on palpation of the masticatory muscles and temporomandibular joints) in 2000 and 2011 and responded to questions on TMD pain symptoms in 2011. Hostility was measured using the Cynical Distrust Scale, somatization was measured using the Symptom Checklist-90, and depressiveness using Beck’s Depression Inventory-21. Four subgroups were formed based on the presence of TMD pain: no pain, pain in 2000 only, pain in 2011 only, and pain in 2000 and 2011. Analyses included chi-square test cross-sectionally, and multinomial logistic regression longitudinally with the level of hostility in 2000 as the predictor. Mediation analysis was performed using Hayes’ Process v3.5. Results: Those with higher hostility showed a higher prevalence of TMD pain. Longitudinally, the association of hostility with TMD pain in 2000 only, and with TMD pain in both years, was mediated either by somatization only or by depressiveness that was mediated by somatization. In those with TMD pain in 2011 only, the association was mediated by depressiveness that was mediated by somatization. Conclusion: Hostility increased the risk of TMD pain through increases in depressiveness and somatization

How many third molars remain unnoticed in a population survey without panoramic radiographs?

Abstract Objective: The aim of the study was to compare the findings of clinical examination and panoramic radiograph regarding the occurrence of third molars in a population survey to find out how many third molars remain clinically unnoticed. Materials and methods: A two-staged stratified cluster-sampling method was used to select 8028 participants representing the adult population aged 30 years and older. Clinical oral examinations and panoramic radiographs were carried out for 5989 subjects (46% men, 54% women; mean age 52.5, SD 14.6; range 30–97 years). Clinical recordings of the presence of third molars were compared with the radiographs. Statistics included chi-squared, Fisher’s, Wilcoxon’s, and Kruskal-Wallis tests. Results: In the 5989 subjects, 3742 third molars were recorded in the clinical examination, and 5912 were observed in the panoramic images, a difference of 2170 teeth. Furthermore, related to 3668 (61%) of the third molars, both clinical and radiographic recordings were attributed to the same third molar, while 2244 third molars were observed only in the panoramic image, and 74 only in the clinical examination. In every age group, the mean number of third molars per subject was larger radiographically compared with the clinical recordings (means for all 0.99 vs. 0.62; P < 0.001). Conclusion: Numbers of third molars, recorded in clinical examination alone, are underreported by approximately one-third compared with radiographic findings. Clinical relevance: The numbers of third molars in a population survey without a panoramic radiograph do not reflect the total number of third molars in a population

Low-grade inflammation as a potential mediator between depressive symptoms and temporomandibular pain:an 11-year follow-up study on Finnish adults

Abstract Background: Low-grade inflammation and depressiveness have been associated with chronic pain conditions. Objective: To examine whether low-grade inflammation mediates the association between depressive symptoms and temporomandibular (TM) pain in Finnish adults based on the Health 2000/2011 Surveys (BRIF8901). Methods: The sample comprised subjects who underwent clinical TM pain examination (pain on palpation of the masticatory muscles and temporomandibular joints) in 2000 and 2011 and responded to questions on TM pain symptoms in 2011. The serum level of hs-CRP was obtained in both years, and depressiveness was assessed using the Beck Depression Inventory-21 (BDI-21) in 2000 and BDI-13 in 2011. Four subgroups were formed based on the presence of TM pain: No pain, pain in 2000-only, pain in the 2011-only, and pain in both-years. Analyses included Rao Scott’s chi-square test cross-sectionally, and multinomial logistic regression longitudinally with the level of hs-CRP and BDI-21 score in 2000 as predictors. Mediation was tested using Hayes A. Processv3.5. Results: Higher BDI-21/-13 and hs-CRP levels corresponded to higher prevalences of TM pain in both years. Longitudinally, in men, higher hs-CRP level predicted TM pain in 2000-only and TM pain in both-years. Higher BDI-21 score predicted having TM pain in 2011-only. In women, higher BDI-21 score predicted TM pain in 2000-only and having TM pain in both-years. Both BDI-21 and hs-CRP had a direct effect on TM pain outcome with no mediation detected. Conclusions: While depressiveness may increase the risk of chronic TM pain in women, the risk in men is increased by low-grade inflammation

Role of psychosocial factors on treatment outcome of temporomandibular disorders

Abstract Objectives: The aim of this randomized controlled study was to investigate the effect of depressive and non-specific physical symptoms on treatment outcome of temporomandibular disorders (TMD). Material and methods: Eighty TMD patients were randomly assigned to splint group (n = 39) and control group (n = 41). The patients were classified in terms of depressive and non-specific physical symptoms as normal, moderate or severe using Research Diagnostic Criteria for Temporomandibular Disorders Axis II protocol. The effect of depressive and non-specific physical symptoms on the intensity of facial pain, as measured with visual analogue scale (VAS) was estimated with linear mixed models. The patients’ subjective estimates of the effects of treatment and TMD symptom severity were inquired at 1-year follow-up. Results: At baseline and during the follow-up there were no significant differences in VAS scores between patients in different Axis II subscales. According to the mixed linear regression, depressiveness or nonspecific physical symptoms separately were not significantly associated with the VAS during the study. The association of VAS with depressive (p = .073) and nonspecific physical symptoms (p = .088) approximated statistical significance. Patients with moderate or severe nonspecific physical symptoms (with pain items) at baseline had more frequently moderate, severe or intolerable TMD symptoms after the treatment compared to those who were classified in normal subgroup. Conclusions: The present study gave some indication of a possible negative effect of depressive and nonspecific physical symptoms (with pain items) on TMD treatment response. However, the results should be regarded as preliminary, and further studies with larger sample size are needed to confirm the results

Effect of smoking on periodontal health and validation of self-reported smoking status with serum cotinine levels

Abstract Objectives: To investigate whether self-reported smoking and serum cotinine levels associate with periodontal pocket development and to determine the accuracy of self-reported smoking using serum cotinine. Materials and methods:This 4-year prospective cohort study included data from 294 dentate adults, aged ≥30 years, who participated in both the Health 2000 Survey and the Follow-up Study of Finnish Adults’ Oral Health. Subjectively reported smoking status (daily smokers n = 62, occasional smokers n = 12, quitters n = 49, and never-smokers n = 171), serum cotinine levels, demographic factors, education level, dental behaviours and medical history were collected at baseline. The outcome measure was the number of teeth with periodontal pocketing ≥4 mm over 4 years. Results:Self-reported daily smokers had 1.82 (95% CI: 1.32–2.50) higher incidence of deepened periodontal pockets than never-smokers. A positive association was observed between serum cotinine (≥42.0 μg/L) and the development of periodontal pockets. The misclassification rate of self-reported smoking was 6%. Conclusions:Both self-reported daily smoking and higher serum cotinine were associated with periodontal pocket development. Self-reported smoking was fairly accurate in this study. However, higher cotinine levels among a few self-reported never-smokers indicated misreporting or passive smoking. Thus, self-reports alone are not enough to assess the smoking-attributable disease burden

Periodontal condition and ultrasound-based measures of arterial stiffness:results of the Health 2000 Survey

Abstract Background: Periodontitis has been associated with inflammatory processes in arterial walls such as impairment in endothelial function and thickening of intima media. As inflammation plays a role also in arterial stiffening, an association between periodontal inflammation and arterial stiffness can be expected. So far, conflicting results of the association between periodontal disease and arterial stiffness have been reported. Many of the earlier studies were conducted in specific populations and heterogeneous measures of both arterial stiffness and periodontal status were used. In this population-based study we aimed to investigate whether periodontal pocketing and gingival bleeding are associated with ultrasound-based measures of arterial stiffness. Methods: In this cross-sectional study, two sets of data based on the national Health 2000 Survey in Finland were formed. Data set I comprised never-smoking 45–64-year-old dentate (≥ 10 natural teeth), non-diabetic, non-rheumatic, non-obese (BMI ≤ 30 kg/m²), non-hypertensive subjects with no coronary artery disease or ongoing lipid-lowering medications (n = 157). Data set II was formed of an unrestricted 45–74-year-old dentate population (n = 536). Four arterial stiffness measures (carotid artery compliance, Peterson’s elastic modulus, Young’s elastic modulus and beta stiffness index) based on an ultrasound examination of the common carotid artery were used. Periodontal parameters included the number of teeth with ≥ 4 mm deep periodontal pockets and the number of sextants with gingival bleeding. β-estimates, confidence intervals, and p-values were obtained from linear regression models. Results: In Data set I, the adjusted β-estimates for the association between the number of teeth with ≥ 4 mm deep periodontal pockets and Peterson’s elastic modulus and Young’s elastic modulus were 15.80 (p = 0.12) and 61.02 (p = 0.22), respectively. The respective β-estimates were 31.06 (p = 0.17) and 121.16 (p = 0.28) for the association between the number of bleeding sextants and these two stiffness measures. The results in Data set II were in line with the results in Data set I, with the exception that the adjusted β-estimates for the associations between Peterson’s elastic modulus and Young’s elastic modulus and periodontal parameters were closer to null. Conclusions: This population-based study did not provide evidence of an association between periodontal condition and arterial stiffness

Association between periodontal condition and blood pressure is confounded by smoking

Abstract Objective: To investigate the role of smoking as a confounding factor in the association between periodontal pocketing and blood pressure. Materials and methods: After restriction to 45–64-year-old subjects without hypertension, diabetes, rheumatic diseases, obesity and with no history of cardiovascular diseases or ongoing lipid-lowering medications, the study population consisted of 307 subjects of the Health 2000 Survey in Finland. Systolic and diastolic blood pressure and pulse pressure (mmHg) were used as outcome variables. Periodontal condition was measured by the number of teeth with ≥4 mm periodontal pockets. β-estimates and 95% confidence intervals (CI) were obtained from linear regression models. Analyses were made in the whole study population and stratified according to smoking habits/history. Results: The number of teeth with ≥4 mm periodontal pockets associated statistically significantly with systolic blood pressure and pulse pressure in the whole study population. Among never-smokers or daily smokers, there were no consistent nor statistically significant associations between the number of teeth with ≥4 mm periodontal pockets and systolic/diastolic blood pressure or pulse pressure. Conclusions: Smoking appeared to confound the association between periodontal condition and blood pressure. Thorough control for the effect of smoking was not obtained using multivariate models
