Impact of the anti-inflammatory diet on serum high-sensitivity C-Reactive protein and new-onset frailty in community-dwelling older adults: A 7-year follow-up of the Kashiwa cohort study.

Aim: Chronic inflammation is a pathophysiological cause of age-related diseases, including frailty. Although diet is a determinant of inflammation, few prospective studies have investigated its role in frailty onset. This study used the dietary inflammatory index to investigate whether a proinflammatory diet affects the incidence of frailty in a 7-year follow-up of older Japanese adults.

Integrated effects of nutrition-related, physical, and social factors on frailty among community-dwelling older adults: A 7-year follow-up from the Kashiwa cohort study.

Aim: To investigate the impact of nutrition-related, physical, and social factors as well as their transitions on frailty over a 7-year follow-up period among community-dwelling older adults.

Methods: Participants were 868 non-frail older adults. Frailty was assessed using the Cardiovascular Health Study index.

Validity of a simple self-reported questionnaire "Eleven-Check" for screening of frailty in Japanese community-dwelling older adults: Kashiwa cohort study.

Purpose: Frailty was indicated to be closely related to older adults' lifestyles, especially in nutrition-related factors (such as balanced diet and oral functions), physical factors, and social factors in our previous study. Here, we developed an "Eleven-Check" (EC) questionnaire containing the aforementioned three factors. This study tested whether the EC questionnaire can estimate frailty in community-dwelling older adults.

Playing basketball and volleyball during adolescence is associated with higher bone mineral density in old age: the Bunkyo Health Study.

Exercise is beneficial for increasing areal bone mineral density (aBMD) in adolescence and maintaining it in old age. Moreover, high-impact sports are more effective than low-impact sports in increasing aBMD. This study aimed to determine the types of adolescent sports played in school-based sports clubs associated with aBMD in old age.

The Co-Design/Co-Development and Evaluation of an Online Frailty Check Application for Older Adults: Participatory Action Research with Older Adults.

Frailty is an age-related condition characterized by a decline in physical capacity with an increased vulnerability to stressors. During the COVID-19 pandemic, there was considerable progression in frailty in older adults. Therefore, an online frailty check (FC) is required for continuous screening, especially acceptable to older adults.

Multidimensional background examination of young underweight Japanese women: focusing on their dieting experiences.

Introduction: This study examines the background of underweight young women in Japan from multiple perspectives, focusing on whether they have ever dieted.

Methods: A screening survey was administered to 5,905 underweight (BMI < 18.5 kg/m2) women aged 18-29 years, who could report their birth weight recorded in their mother-child handbook.

Effects of exercise habits in adolescence and older age on sarcopenia risk in older adults: the Bunkyo Health Study.

Background: Sarcopenia, defined as an age-associated loss of skeletal muscle mass and function, is a major risk factor for requiring long-term care. Because physical activity in adolescence and older age enhances peak muscle function in youth and prevents muscle function decline in older age, older adults with exercise habits during both periods may be at a lower risk for sarcopenia. We investigated the relationship between exercise habits in adolescence and older age and sarcopenia and its components in community-dwelling older Japanese adults.

Predictive validity of the Questionnaire for Medical Checkup of Old-Old for functional disability: Using the National Health Insurance Database System.

Aim: To enhance health services that can address multifaceted issues, the Questionnaire for Medical Checkup of Old-Old (QMCOO) was strategically developed to ascertain frailty status. Using the National Health Insurance database system, we aimed to clarify whether the QMCOO can predict new certifications for long-term care for disabilities.

Method: Of 20 151 adults aged ≥75 years who underwent health checkups in Kashiwa City, Japan, in fiscal year 2020 (examination rate 36.

Association of Genotypes and Alcohol Intake with Dietary Patterns: The Bunkyo Health Study.

Dietary habits are associated with various diseases and assessed by dietary patterns (DPs). Since the genotype is correlated with alcohol and several food preferences, this genotype is probably associated with DPs. In this cross-sectional study of 1612 elderly adults, we investigated the effects of the genotype on DPs and the mediating role of alcohol intake.

Associations of Nutrition-Related, Physical, and Social Factors and Their Combinations with Sarcopenia in Community-Dwelling Older Adults: Kashiwa Cohort Study.

Background: Sarcopenia is a major cause of frailty, which relates to nutrition-related, physical, and social factors. In this study, we aimed to discuss the cross-sectional association of sarcopenia with the above three factors both individually and comprehensively.
