RESUMO
Psychosocial stress is generally associated with adverse health behaviors and has been linked to the development of cardiovascular diseases (CVD). Recently, an individual's sense of coherence (SOC), which is a concept that reflects the ability to cope with psychosocial stress, has been recognized as an essential component of long-term health and stress management. The association between SOC and traditional and alternative atherosclerotic markers in a community sample, however, has not been thoroughly investigated. In the present study, we evaluated stress management capability and psychological conditions using the Japanese version of the Sense of Coherence-13 (SOC-13) Scale, supplemented by the General Health Questionnaire-12 (GHQ-12) that screens for minor psychiatric disorders. The study subjects were 511 adults, median age 64 years (range 48-70), who participated in a regular medical screening program in Nagasaki Prefecture, Japan. We then correlated our findings with atherosclerotic risk factors in the same community sample, such as body mass index (BMI) and proper and regular sleeping habits. We found that close association between good stress management capability and lower BMI and/or regular sleeping habits in elderly Japanese. This provides strong evidence that BMI and sleep management are contributory to SOC. If the ability to cope with psychosocial stress is important to the prevention of CVD, then weight control and proper sleep habits must be emphasized from a psychosocial stress-management perspective as well as a physical one.

The relationship between the reported ambient dose equivalent (H*(10)) and the individual dose rate recorded by medical staff in Fukushima City after the accident at the Fukushima Daiichi nuclear power plant was evaluated, following a 9.0-magnitude earthquake that struck the east coast of Japan. Personal dose equivalent (H(p)(10)) ranged from 0.08 to 1.63 µSv h(-1) and H*(10) ranged from 0.86 to 12.34 µSv h(-1). H(p)(10) from March to July 2011 were significantly lower than H*(10). The relationships between these dose equivalents were moderately correlated. The regression equation was calculated as follows: H(p)(10)=0.0696×H*(10)+0.0538. The preliminary data of this study show that, in Fukushima, the individual dose is much lower than that determined H*(10). It is important to evaluate H(p)(10) in order to lessen the anxiety of the general population in Fukushima.

Osteoporosis is a common disorder in aging populations that imposes considerable health problems. Tartrate-resistant acid phosphatase type 5b (TRAP-5b) is derived from osteoclasts, and is involved in normal bone homeostasis. Recently, a novel assay system for TRAP-5b, the fragments absorbed immunocapture enzymatic assay method, has been developed. To evaluate the suitability of TRAP-5b as a screening marker for bone mineral density (BMD), we explored the correlations between serum TRAP-5b concentrations and laboratory findings, body mass index, or BMD in 462 community-dwelling elderly individuals (249 men and 213 women, age 73.4±6.5 years) who participated in a regular medical screening program. By multivariate linear regression analysis adjusted for confounding factors, TRAP-5b was significantly correlated with body mass index (ß=-0.005, p=0.043), alkaline phosphatase, a marker for osteoid formation and calcification (ß=0.001, p<0.001), and triglyceride (ß=-0.097, p=0.016) in men, and with body mass index (ß=-0.009, p=0.025), alkaline phosphatase (ß=0.001, p<0.001), calcium (ß=-0.059, p=0.039), and bone trabecular area ratio (ß=-0.47, p=0.025) in women. In conclusion, the elevated serum level of TRAP-5b is independently correlated with the decreased BMD in women, but not in men. Because measurement of TRAP-5b is not affected by food intake, and blood samples can be collected at any time of the day, we suggest the suitability of serum TRAP-5b as a simple marker for the evaluation of BMD in women.

Oral dryness is common among aging individuals and its objective evaluation is an important issue for improving their oral health. In the present study, we measured the objective mucosal moisture in elderly individuals with a moisture checker and evaluated its relation with laboratory findings and subjective oral status. The subjects were 502 adults (244 men and 258 women), with a mean age of 72.3 +/- 6.7 years, who participated in a regular medical screening program in Nagasaki Prefecture, Japan. We evaluated the moisture of the oral mucosa by measuring the weight percentage of water content in the oral epithelium, subjective oral dryness, self-assessed chewing ability ["good" ("able to chew all foods") or "poor" ("able to chew soft foods only" and "unable to chew any foods")], and laboratory findings. The values obtained with a moisture checker, which represent objective oral mucosal moisture, were significantly lower in women with poor chewing ability than those with good chewing ability (28.2 +/- 2.4% vs. 29.2 +/- 2.0%, p = 0.004) and in all subjects (28.4 +/- 2.4% vs. 29.1 +/- 2.0%, p = 0.004), but not in men (28.6 +/- 2.5% vs. 29.0 +/- 2.0%, p = 0.27). When multiple logistic regression analysis was performed on confounding factors, older age (OR: 1.24, p = 0.015), women (OR: 1.70, p = 0.016), and anemia (OR: 1.96, p = 0.030) were significantly associated with self-assessed chewing ability. Our current study indicates that poor chewing ability is associated with lower mucosal moisture in elderly individuals.
