Association of Physical Performance and Pain With Fear of Falling Among Community?Dwelling Japanese Women Aged 65 Years and Older

Our aim was to explore the association of physical performance and pain with fear of falling among community-dwelling Japanese women. The subjects were 278 women aged 65 years and over. We collected information on fear of falling, painful joints, comorbidities, falls in the previous year, and cataracts. Walking time (distance of 6 m), chair stand time (5 times), grip strength, the timed up and go test (TUG), and functional reach were measured. The prevalence of fear of falling was 36.3%, and it increased with age, but it was not significant (P=0.081). Multivariate logistic regression analysis showed that poor physical performance (longer walking time, longer chair stand time, weaker grip strength, and longer TUG) and pain (low back, and upper and lower extremity pain) were significantly associated with fear of falling after adjusting for age, body mass index, comorbidities, falls in the previous year, and cataracts. Maintaining physical functioning and managing pain may be important for elderly women with fear of falling

Vitamin K deficiency, evaluated with higher serum ucOC, was correlated with poor bone status in women

BACKGROUND: An increase in serum undercarboxylated osteocalcin concentrations suggests vitamin K deficiency. Clinical intervention studies suggested that the vitamin K supplementation might contribute to preventing bone loss in postmenopausal women. Evidence on the relationship between serum undercarboxylated osteocalcin (ucOC) levels and bone parameters of quantitative ultrasound (QUS) is limited. We examined the correlation between serum ucOC concentrations and bone status as measured by QUS among middle-aged and older Japanese men and women. METHODS: The subjects were community-dwelling men (n = 358) and women (n = 503) aged ? 40?years in Japan. Heel QUS parameters, including the stiffness index, speed of sound, and broadband ultrasound attenuation, were measured. Serum ucOC concentrations were measured by electrochemiluminescence immunoassay. Grip strength was measured in the dominant hand. Information on alcohol drinking, current smoking, exercise, and menopause in women was collected. RESULTS: Serum ucOC concentrations were significantly associated with age in both sexes. Serum ucOC concentrations in men were higher at ? 80?years than those in the age groups of 40-49, 50-59, and 60-69?years. Serum ucOC concentrations in women were higher in the age groups of 50-59 and 60-69?years than those at 40-49?years. Partial correlation analysis adjusting for covariates (age, body mass index, grip strength, alcohol drinking, current smoking, and exercise in men; age, body mass index, grip strength, alcohol drinking, current smoking, exercise, and menopause in women) showed that serum ucOC concentrations were negatively significantly correlated with all QUS parameters in women. Serum ucOC concentrations were not correlated with them in men. CONCLUSIONS: Vitamin K deficiency, evaluated with higher serum ucOC, was correlated with poor bone status in women

Association between self-reported walking speed and calcaneal stiffness index in postmenopausal Japanese women

Background: Osteoporosis and related fractures, a worldwide public health issue of growing concern, is characterized by compromised bone strength and an increased risk of fracture. Here we show an association between self-reported walking speed and bone mass among community-dwelling postmenopausal Japanese women aged 50 years and older. Design; cross-sectional study: Setting and Participants; The survey population included 1008 postmenopausal women 50?92 years of age residing in rural communities. Methods: Self-reported walking speed was ascertained by asking the participants: “Is your walking speed faster than others of the same age and sex?” to which participants responded “yes (faster)” or “no (moderate/slower).” Calcaneal stiffness index was measured. Results: Women with a faster self-reported walking speed were younger and had a lower BMI, higher stiffness index, and higher grip strength than women with a slower walking speed. Multiple linear regression analysis adjusted for age, BMI, grip strength, comorbidity, current smoking, and alcohol drinking status showed a significant association between faster self-reported walking speed and higher calcaneal stiffness index (p < 0.001). Conclusions: Our findings suggest that questionnaires of walking speed may be useful for predicting bone mass and that a fast self-reported walking may benefit bone health in postmenopausal women

Effect of self-reported walking difficulty on bone mass and bone resorption marker in Japanese people aged 40?years and over

Background: This study aimed to examine the association of walking difficulty with bone mass or bone turnover among community-dwelling Japanese people aged 40 years and older. Methods: We studied 1097 community-dwelling Japanese people aged 40 years and older (379 men and 718 women) who were invited to participate in periodic health examinations in 2006?2009. Walking difficulty was defined as having difficulty walking 100 m on a level surface (self-administered questionnaire). Calcaneal stiffness index (bone mass) was measured by quantitative ultrasound. Spot urine samples were collected, and urinary N-terminal cross-linking telopeptide of type I collagen (NTx) was measured. Values were corrected for creatinine (Cre) concentration. Results: The prevalence of walking difficulty was significantly higher in women than in men (7.4 vs. 3.4 %, p?=?0.011) and significantly increased with age in men (p for trend?=?0.02) and women (p for trend <0.001). In univariate analysis, men and women with walking difficulty were older (p?<?0.001) and had a lower stiffness index (p?<?0.001), compared with those without walking difficulty. Among women, individuals with walking difficulty had significantly higher urinary NTx/Cre than those without walking difficulty (p?<?0.001); however, this was not so among men (p?=?0.39). Multiple regression analysis adjusted for age, weight, and menopausal status showed a significant association between walking difficulty and lower stiffness index in men (p?=?0.004) and women (p?=?0.005). In women, walking difficulty was significantly associated with higher NTx/Cre (p?=?0.001), but not in men (p?=?0.35). Conclusions: Walking difficulty may contribute to low bone mass in both sexes but might cause high bone turnover in women only

Associations of vertebral deformities and osteoarthritis with back pain among Japanese women: the Hizen-Oshima study

We examined the spinal distribution of the types of vertebral deformities and the associations of vertebral deformities and osteoarthritis with back pain in Japanese women. Midthoracic and upper lumbar vertebrae were more susceptible to deformity. Vertebral deformity and osteoarthritis were frequent and were associated with back pain. Introduction: Vertebral fractures due to osteoporosis and osteoarthritis are both common and significant health problems in aged people. However, little is known about the descriptive epidemiology of the individual deformity types and the relative clinical impact in women in Japan. Methods: Lateral radiographs were obtained from 584 Japanese women ages 40 to 89 years old. Deformities were defined as vertebral heights of more than 3 standard deviations (SDs) below the normal mean. Osteoarthritis was defined as Kellgren-Lawrence (KL) grade 2 or higher. Information on upper or low back pain during the previous month was collected by questionnaire. We compared the spinal distribution of the three types of vertebral deformities (wedge, endplate, and crush) typical of fractures and examined the associations of number and type of vertebral deformities and osteoarthritis with back pain. Results: Fifteen percent of women had at least one vertebral deformity and 74% had vertebral osteoarthritis. The prevalence of upper or low back pain was 30.1%. Deformities were most common in the midthoracic and upper lumbar regions and wedge was the frequent type, followed by endplate and crush. Multiple logistic regression analysis showed that the odds of back pain was 3.0 (95% CI 1.5-6.3) times higher for women with a single wedge deformity and 3.2 (95% CI 1.0 - 0.6) times higher for women with two or more wedge deformities, compared to women with no wedge deformity. Vertebral osteoarthritis was associated with back pain (OR 1.8, 95% CI 1.1-2.9), independent of other covariates including age and deformities. Conclusion: Our results in this group of Japanese women are similar to and consistent with results reported previously in other populations of Japanese and Caucasians

Environment Friendly Agricultural Brand “Cool Vege” Through Carbon Sequestration by Biochar for Sustainable Management of Food and Water = Cool The Earth from The Dining Table with COOL Vege =

The reduction of of greenhouse gas to mitigate or adapt to drastic climate change are one of the most important issues for human beings. On the other hand, rural development is also important issue for sustainable rural natural resources to secure food and water. Then, we propose the new socio-economic scheme to solve these issues at the same time through biochar carbon capture and sequestration. This scheme contains 4 measure factors that 1) Carbon Capture &amp; Storage(CCS) via biochar, 2) Biochar CCS should be carried out at agricultural lands for rural development, 3) Biochar CCS should be monitored and measured to generate carbon credits and social creditability, 4) The ECO-brand “Cool Vege” for agricultural products derived from biochar CCS. And, it consists of many stake holders and actors that local community, compost center, farmers, CCS local committee consisted by local governments and universities as scientific authority, companies, retailers and normal citizen as consumers. Therefore, when proceeding this scheme, it is needed to have holistic aspect like bird view
