Relationship between Chewing Ability and Nutritional Status in Japanese Older Adults: A Cross-Sectional Study.

ABSTRACT:

Objectives

This study aimed to determine the relationship between objective chewing ability and the nutritional status of Japanese community-dwelling elders.

Design

A cross-sectional study.

Participants

A total of 509 community-dwelling elders living in the Tokyo metropolitan area participated in a comprehensive survey conducted in October 2013.

Measurements

The basic characteristics were sex, age, and body mass index. Undernutrition was examined through serum albumin levels. Chewing ability was examined through color-changeable xylitol gum by evaluating the color changes in chewing gum. Nutritional intake was examined using the semi-quantitative food frequency questionnaire.

Results

In the poor chewing ability group, all nutrient intake levels were significantly low, except for carbohydrates, and intake levels for all food groups were significantly low, except for cereals, confectionery, sugars, seasonings, and spices. Additionally, after adjusting for covariates for sex, age, Tokyo Metropolitan Institute of Gerontology-Index of Competence (TMIG-IC) score, Mini-Mental State Examination (MMSE) score, body mass index (BMI), stroke, number of functional teeth, energy intake, and protein intake, chewing ability was found to be significantly associated with undernutrition.

Conclusion

We concluded that chewing ability was closely associated with nutrient and different food groups' intake, as well as undernutrition, among Japanese community-dwelling elders. Thus, to ensure comprehensive nutritional management, nutritionists and dentists should collaborate when treating the same patients.

Project description:Participation in a sports group is key for the prevention of incident functional disability. Little is known about the correlates of older adults' participation in sports groups, although this could assist with the development of effective health strategies. The purpose of this study was to identify the demographic and biological, psychosocial, behavioral, social and cultural, and environmental correlates of sports group participation among Japanese older adults.Data were obtained from the Japan Gerontological Evaluation study, which was a population-based cohort of people aged ≥65 years without disability enrolled from 31 municipalities across Japan (n = 78,002). Poisson regression analysis was used to determine the associations between the factors and participation in sports groups.Non-regular participation in sports groups was associated with lower educational level, being employed, and working the longest in the agricultural/forestry/fishery industry among the demographic and biological factors and poor self-rated health and depression among the psychosocial factors. Of the behavioral factors, current smoking was negatively associated and current drinking was positively associated with regular participation in sports groups. Among the social and cultural factors, having emotional social support and participating in hobby clubs, senior citizen clubs, or volunteer groups were associated with a high prevalence of participation in sports groups. Perceptions of the presence of parks or sidewalks, good access to shops, and good accessibility to facilities were positively associated with participation in sports groups among the environmental factors.Our study suggests that the promotion of activities that could increase older adults' participation in sports groups should consider a broad range of demographic and biological, psychosocial, behavioral, social and cultural, and environmental factors. Although future longitudinal studies to elucidate the causal associations are needed, encouraging participation in community groups through social networks might be effective for participation in sports groups.

Project description:OBJECTIVES:To characterize assessments of a patient's ability to report elder abuse within the context of an emergency department (ED)-based screen for elder abuse. DESIGN:Cross-sectional study in which participants were screened for elder abuse and neglect. SETTING:Academic ED in the United States. PARTICIPANTS:Patients, aged 65 years and older, presenting to an ED for acute care were assessed by trained research assistants or nurses. MEASUREMENTS:All patients completed the four-item Abbreviated Mental Test 4 (AMT4), then completed a safety interview (using the Emergency Department Senior Abuse Identification tool) designed to detect multiple domains of elder abuse and received a physical examination. Based on the cognitive assessment and safety interview, assessors ranked their confidence in the patient's ability to report abuse as absolutely confident, confident, somewhat confident, or not confident. To assess interrater reliability, two assessors independently rated confidence for a subset of patients. RESULTS:Assessors suspected elder abuse in 18 of 276 patients (6.5%). Assessors were absolutely confident in the patient's ability to report abuse for 95.7% of patients, confident for 2.5%, somewhat confident for 1.5%, and not confident for 0.3%. Among patients with an AMT4 of 4 (n = 249), assessors were confident or absolutely confident in 100% of patients. Among patients with an AMT4 of less than 4 (n = 27), they were confident or absolutely confident in the patient's ability to report abuse for 81% of patients, including 11 of 12 patients with mild cognitive impairment and 7 of 11 patients with severe cognitive impairment. For patients receiving paired evaluations (n = 131), agreement between assessors regarding patient ability to report abuse was 97% (κ = 0.5). CONCLUSIONS:In this sample of older adults receiving care in an ED, research assistants and nurses felt that the vast majority were able to report elder abuse, including many patients with cognitive impairment.

Project description:BackgroundNutritional status, health risk behaviors, eating habits, and other comorbidities (such as diabetes) may be associated with recommended amounts of physical activity (PA) and exercise (EX) in healthy older adults. However, these associations are still unclear for older hypertensive adults, who require greater care from health professionals. The purpose of this study was to associate the nutritional status, health risk behaviors, eating habits, and the presence of diabetes with recommended amounts of physical activity and exercise practice of older hypertensive adults.MethodsTen thousand seven hundred eighty-nine older hypertensive adults (70.9 ± 7.4 years) from the VIGITEL telephone survey were classified according to PA levels (insufficiently active/sufficiently active) and EX practice (non-practitioners/practitioners). Binary logistic regression was used to observe the odds ratio (OR) between independent variables (nutritional status [body mass index], sociodemographic characteristics [age/sex/years of study], risk behaviors [screen time/alcohol/tobacco consumption], eating habits [minimally/ultra-processed foods consumption score], and the presence of diabetes) with recommended amounts of PA/EX (dependent variable).ResultsHighest nutritional status (ORPA = 0.975 [95%-CI: 0.965 - 0.985]; OREX = 0.981[95%-CI: 0.972 - 0.991]), age (ORPA = 0.955 [95%-CI: 0.949 - 0.961]; OREX = 0.980[95%-CI: 0.975 - 0.986]), screen time (ORPA = 0.909[95%-CI: 0.835 - 0.990]), alcohol consumption (ORPA = 0.683[95%-CI: 0.621 - 0.758]; OREX = 0.702[95%-CI: 0.637 - 0.779]), tobacco (ORPA = 0.601 [95%-CI: 0.492 - 0.736]; OREX = 0.464[95%-CI: 0.384 - 0.562]) ultra-processed foods consumption score (ORPA = 0.896[95%-CI: 0.871 - 0.921]; OREX = 0.886[95%-CI: 0.863 - 0.909]) and having diabetes (ORPA = 0.780[95%-CI: 0.708 - 0.859]; OREX = 0.831[95%-CI: 0.759 - 0.909]) reduced the odds of being sufficiently active/practicing exercise (p < 0.05). Male sex (ORPA = 1.633[95%-CI: 1.491 - 1.789]; OREX = 1.247[95%-CI: 1.140 - 1.363]), years of study (ORPA = 1.026[95%-CI: 1.018 - 1.035]; OREX = 1.050[95%-CI: 1.041 - 1.058]), and minimally processed foods consumption score increased the odds of being sufficiently active/practicing exercise (ORPA = 1.132[95%-CI: 1.109 - 1.155]; OREX = 1.167[95%-CI: 1.145 - 1.191], respectively; p < 0.05).ConclusionNutritional status, health risk behaviors, eating habits, and the presence of diabetes were associated with the odds of older hypertensive adults complying with PA and EX recommendations. The results may help health professionals understand how these factors are associated with the changes of older hypertensive adults participating in physical activity and exercise.
