Article Synopsis
- - The study aims to find out which dietary nutrients might be linked to joint space narrowing (JSN) and osteophytosis in the knees of participants from the ROAD study.
- - Analyzing 827 participants, it was found that while men showed no links, women’s intake of vitamins K, B1, B2, B6, and C was significantly associated with joint health measures after adjusting for factors like age and BMI.
- - The results suggest that low intake of specific vitamins may protect against knee osteoarthritis in women, indicating potential avenues for treatment.
OBJECTIVE: The objective of the present study is to identify dietary nutrients associated with joint space narrowing (JSN) and osteophytosis at the knee in a population-based cohort of the Research on Osteoarthritis/osteoporosis Against Disability (ROAD) study. METHODS: From the baseline survey of the ROAD study, 827 participants (305 men and 522 women) in a rural cohort were analyzed. Dietary nutrient intakes for the last month were assessed by a self-administered brief diet history questionnaire.

Development of treatment guidelines requires further knowledge about the etiology and natural history of DNDLS in the elderly.
Methods: To identify the cumulative incidence and radiographic features of DNDLS in the elderly, the authors reanalyzed the results of lumbar radiographic examinations from the Miyama study, which was originally conducted in a Japanese rural community to determine the prevalence of vertebral fractures in Japanese people.
Objective: To clarify the individual associations of joint space narrowing (JSN) and osteophytosis at the knee with quality of life (QOL) in Japanese men and women using a large-scale population-based cohort from the Research on Osteoarthritis Against Disability (ROAD) study.
Methods: The associations of minimum joint space width (JSW) and osteophyte area in the medial compartment of the knee with QOL parameters, such as the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), were examined. Minimum JSW and osteophyte area in the medial compartment of the knee were measured using a computer-aided system for the diagnosis of knee osteoarthritis.
Article Synopsis
- The study aimed to investigate the prevalence of falls in different sex and age groups in Japan, particularly focusing on how bone and joint diseases relate to falls.
- Researchers analyzed data from 587 men and 1,088 women aged around 65 years, finding that 13.5% of men and 19.0% of women experienced falls in the past year.
- They discovered that while men had fewer factors linked to falls, women had significant associations between lower back pain, knee pain, and multiple falls, suggesting a need for further attention on these issues.
Article Synopsis
- The study conducted cross-sectional surveys to assess the health-related quality of life (QOL) in men with low back pain and knee pain, focusing on a population-based cohort.
- It aimed to determine how much these pains, along with conditions like vertebral fracture and knee osteoarthritis, affect the quality of life among older men.
- Findings revealed that low back pain significantly decreases QOL more than knee pain, particularly when combined with vertebral fractures.
Article Synopsis
- The study examined how knee and low back pain affect the quality of life (QOL) in Japanese women, utilizing various health assessment tools to gather data from 1,369 women aged over 40 from a larger cohort of 3,040 participants.
- Findings indicated that both knee pain and low back pain led to significantly lower QOL scores, with knee osteoarthritis (KL grade = 4) impacting QOL the most for women with knee pain.
- Interestingly, for low back pain, no major link was found between the KL grade and QOL loss, but a moderate association was noted between QOL loss and the presence of vertebral fractures (VFx).
Background: The present study sought to identify dietary nutrients associated with the prevalence of radiographic knee osteoarthritis (OA) in the Japanese elderly of a population-based cohort of the Research on Osteoarthritis Against Disability (ROAD) study.
Methods: From the baseline survey of the ROAD study, 719 participants >or=60 years of age (270 men, 449 women) of a rural cohort were analyzed. Dietary nutrient intakes for the previous 1 month were assessed by a self-administered brief diet history questionnaire.
Musculoskeletal diseases, especially osteoarthritis (OA) and osteoporosis (OP), impair activities of daily life (ADL) and quality of life (QOL) in the elderly. Although preventive strategies for these diseases are urgently required in an aging society, epidemiological data on these diseases are scant. To clarify the prevalence of knee osteoarthritis (KOA), lumbar spondylosis (LS), and osteoporosis (OP) in Japan, and estimate the number of people with these diseases, we started a large-scale population-based cohort study entitled research on osteoarthritis/osteoporosis against disability (ROAD) in 2005.

Methods: From the baseline survey of the ROAD study, 1,471 participants age > or =50 years (531 men and 940 women) living in mountainous and seacoast communities were analyzed. Information collected included a lifetime occupational history and details of specific work place physical activities.
