Materials And Methods: In total, 359 older women (age range: 55-74 years) participated in this study. Two periodontal parameters - the number of teeth with a probing pocket depth (PPD) or clinical attachment level (CAL) ≥ 4 mm - were used as the dependent variables.

UCP2 polymorphisms, daily step count, and number of teeth associated with all-cause mortality risk in Sado City: A hospital-based cohort study.

Objective: Uncoupling protein 2 (UCP2) is an ion/anion transporter in the mitochondrial inner membrane that plays a crucial role in immune response, regulation of oxidative stress, and cellular metabolism. UCP2 polymorphisms are linked to chronic inflammation, obesity, diabetes, heart disease, exercise efficiency, and longevity. Daily step count and number of teeth are modifiable factors that reduce mortality risk, although the role of UCP2 in this mechanism is unknown.

Interaction between serum vitamin C levels and smoking on the periodontal condition in older adults.

Background And Objectives: Several epidemiological studies have reported that smokers have a higher prevalence and severity of periodontal disease than do nonsmokers, and that smoking negatively affects nutritional status and is associated with a reduced intake of antioxidants, particularly vitamin C. The present investigation aimed to examine the relationship between serum vitamin C levels and smoking and its influence on the periodontal condition in older adults.

Materials And Methods: A total of 353 respondents met the inclusion criteria and were enrolled in the present study.

This study aimed to evaluate the effects of an oral function training program and indicators of oral health status on improvements in physical performance induced by physical function training in dependent older adults. The participants were 131 potentially dependent older adults (age: ≥65 years) who were randomly divided into two groups: an oral intervention and a control group. All participants underwent physical function training, but only the intervention group took part in the oral function training program.

A 5-year longitudinal association between dietary fermented soya bean (natto) intake and tooth loss through bone mineral density in postmenopausal women: The Yokogoshi cohort study.

Objective: In this 5-year cohort study, we aimed to determine whether the intake of natto, a fermented soya bean food product, has an indirect effect on tooth loss incidence through BMD changes among postmenopausal women.

Background: Evidence indicates (1) that natto has a beneficial effect on bone health and (2) that a decrease in bone mineral density (BMD) is associated with tooth loss.

Methods: The study recruited 435 postmenopausal women (average age = 64.

MAEA rs6815464 polymorphism and periodontitis in postmenopausal Japanese females: A cross-sectional study.

Objectives: Macrophage erythroblast attacher (MAEA) is a membrane protein that regulates the development of mature macrophages by mediating attachment with erythroblasts. A polymorphism rs6815464 (C/G) in MAEA gene was reported to be associated with type II diabetes. Along with diabetes, osteoporosis shows an increased prevalence in postmenopausal females, and both diseases have been reported to be associated with periodontitis.

Materials And Methods: A total of 294 subjects who participated in all follow-up surveys over the 6-year study period were analysed. After dividing subjects into tertiles according to the number of years exposed to smoking, we conducted Poisson regression analysis to compare the incidence rate ratio (IRR) for periodontal disease events during the 6-year study period with beta-3 adrenergic receptor genotype (1: Arg allele carriers, 2: Arg allele non-carriers) for each tertile adjusted for other four variables.

A polymorphism rs6815464 in the macrophage erythroblast attacher gene is associated with low bone mineral density in postmenopausal Japanese women.

Background And Purposes: Osteoporosis and osteopenia are multifactorial diseases characterized by low bone mineral density (BMD) and are susceptible to genetic and environmental risk factors. The macrophage erythroblast attacher (MAEA) was discovered as a protein to mediate the attachment of erythroid cells to macrophages and is essential for bone marrow hematopoiesis. MAEA is expressed in a wide range of cells and tissues including osteoblasts and osteoclasts.
