RESUMO
OBJECTIVE: To examine the association between rheumatoid arthritis (RA) and oral hypofunction (OHF) using propensity score matching (PSM) to adjust for differences between older adults with RA and the general older adult population. METHODS: We conducted a cross-sectional survey among 189 older adults with RA in 2019 (mean age, 71.9 ± 3.6) and 47 178 independent older adult residents in 2016 (mean age, 71.6 ± 4.0), respectively. The questionnaire covered information on socio-demographic characteristics and OHF for both groups. Age, sex, educational level and smoking history were used to determine PSM. Prevalence ratios (PRs) and 95% confidence intervals (CIs) of self-reported OHF (fewer remaining teeth, decreased masticatory function, deterioration of swallowing function and oral dryness) were estimated using Poisson regressions. RESULT: OHF was observed in 44.4% of patients with RA and 27.5% of residents. Before PSM, the prevalence of OHF among patients with RA was higher than that of residents (PR, 1.75; 95% CI, 1.50-2.05). After PSM, there were 189 patients with RA and residents, and the prevalence of OHF among patients with RA was still higher (PR, 1.61; 95% CI, 1.22-2.13). Poisson regression showed that the prevalence of 19 or fewer teeth (PR, 1.06; 95% CI, 0.82-1.36), difficulties eating tough foods (PR, 1.18; 95% CI, 0.90-1.55), difficulties swallowing tea or soup (PR, 1.77; 95% CI, 1.19-2.63), and dry mouth (PR, 2.79; 95% CI, 1.90-4.07) was higher among patients with RA than residents. CONCLUSION: Compared with the general older adult population, patients with RA have a higher prevalence of self-reported OHF.

OBJECTIVE: The present study investigated associations between occupation, job stress, and salivary cortisol levels after psychological tasks. METHODS: We examined 766 (273 men and 493 women) healthy employed Japanese participants aged 21 to 68 years (mean age = 46.4 years, standard deviation = 8.5) with three types of occupation: manager, teacher, and general worker. The Brief Job Stress Questionnaire was used to evaluate participants' job stress levels, including job demand, job control, support from supervisors, and support from coworkers. Salivary cortisol levels were measured at pre-session, post-stressful tasks, and post-relaxation. All samples were assayed using an enzyme-linked immunosorbent assay test. Natural log transformation was applied before statistical analyses. A multiple regression analysis and a repeated measures analysis of covariance were conducted to test associations between occupation and salivary cortisol levels, adjusting for confounding factors. Statistical analyses were conducted separately for men and women. RESULTS: Among both men and women, general workers had higher cortisol levels than managers throughout the experimental session (men 0.6 µg/dL and 0.4 µg/dL, respectively; women 0.5 µg/dL and 0.4 µg/dL, respectively). Job control was positively associated with cortisol levels measured in all sessions, after adjusting for confounding factors (standardized beta 0.15, 0.21, and 0.18 for pre-session, post-stressful-tasks, and post-relaxation, respectively, all p < 0.05). Men with low support from coworkers had higher cortisol levels than those with high support through the sessions (0.6 µg/dL and 0.4 µg/dL, respectively). CONCLUSION: Socioeconomic disparity according to occupational status was related to cortisol levels in Japanese workers. Support from coworkers may be effective for reducing cortisol secretion in men.

INTRODUCTION: Reduced tongue pressure is one of the causes of dysphagia. The purpose of this study was to investigate the relationship between dental findings and tongue pressure, and whether prosthetic treatment prevents reduced tongue pressure. METHODS: This was a cross-sectional study. Participants were 745 community-dwelling adults and elderly persons in the Goto Islands in Nagasaki, who underwent a health checkup for residents in 2015 and 2016. Data were collected on gender; age; grip strength; hemoglobin; Creatinine (Cr); glycated hemoglobin (HbA1c); history of stroke; smoking, drinking, exercise, and walking habits; number of teeth; wearing of removable dentures; functional units of natural teeth (n-FTUs), fixed prostheses (nif-FTUs), and removable dentures (t-FTUs); and tongue pressure. The associations between each variable and tongue pressure were examined using multiple regression analysis. Next, those with 3 or fewer n-FTUs were selected, and differences in tongue pressure were compared between those with 3 or fewer nif-FTUs and those with 4 or more nif-FTUs, using a propensity score matching method. RESULTS: Male gender, weak grip strength, low HbA1c, no drinking, and a low number of teeth were independent factors significantly associated with lower tongue pressure. Among participants with 3 or fewer n-FTUs, the 43 with 4 or more nif-FTUs showed significantly higher tongue pressure than the 43 with 3 or fewer nif-FTUs after propensity score matching, although the number of t-FTUs was not associated with tongue pressure. DISCUSSION/CONCLUSION: Tooth loss was significantly associated with lower tongue pressure. It was suggested that fixed prosthesis treatment might prevent the reduction of tongue pressure, but removable dentures did not have such an effect.

AIM: Recent geriatric studies have focused on maximum voluntary tongue pressure against the palate (MTP) as a diagnostic value for dysphagia, as dysphagia causes aspiration pneumonia. Dysphagia can also cause water intake difficulties, resulting in hypernatremia by indicating the presence of hyperosmotic dehydration. However, no studies have reported on a possible association between reduced MTP and serum sodium levels. METHODS: To evaluate hyperosmotic dehydration within the normal range as an indicator of reduced MTP, we carried out a cross-sectional study of 655 older Japanese community-dwelling men (age ≥60 years) who undertook a general health check-up from 2015 to 2016. As a high concentration of glucose influences serum osmolarity, which might act as a strong confounding factor on this association, the additional analysis was limited to individuals without diabetes. Reduced MTP is defined as a tongue pressure at or under the 20th percentile of the study population (≤24.0 kPa). RESULTS: Independent of classical cardiovascular risk factors, the adjusted odds ratio of reduced MTP for a 1-standard deviation increment of serum sodium (2.21 mEq/L) was 1.29 (95% confidence interval 1.10-1.52). When the analysis was limited to individuals without diabetes, the association became slightly stronger, with an adjusted corresponding value of 1.59 (95% confidence interval 1.21-2.10). CONCLUSIONS: Serum sodium level within the normal range is independently associated with reduced MTP in older Japanese men. This finding suggests that measuring the MTP is clinically relevant for estimating the pathophysiological values (such as dysphagia risks and aspiration pneumonia risks) in daily clinical practice.
