Background: Fear of falling and previous falls are both risk factors that affect daily activities of older adults. However, it remains unclear whether they independently limit daily activities accounting for each other. Methods: We used the data from Round 1 (Year 1) to Round 5 (Year 5) of the National Health and Aging Trends Study. We included a total of 864 community-dwelling participants who provided data on previous falls, fear of falling and limited activities from Year 1 to Year 5 and had no limited daily activities at Year 1 in this study. Previous falls and fear of falling were ascertained by asking participants how many falls they had in the past year and whether they had worried about falling in the last month. Limited daily activities included any difficulties with mobility (e.g., going outside), self-care (e.g., eating), and household activities (e.g., laundering). Generalized estimation equation models were used to examine whether previous falls and fear of falling independently predicted development of limited daily activities adjusting covariates. Results: Participants were mainly between 65 and 79 years old (83 %), male (57 %), and non-Hispanic White (79 %). Among participants who had multiple falls in Year 1, 19.1-31 %, 21.4-52.4 %, and 11.9-35.7 % developed limitations in mobility, self-care, and household activities during Year 2 to Year 5, respectively. Among those who had fear of falling in Year 1, 22.5-41.3 %, 30.0-55.0 %, and 18.8-36.3 % developed limitations in mobility, self-care, and household activities during Year 2 to Year 4, respectively. Fear of falling independently predicted limitations in mobility (Incidence rate ratio [IRR]: 1.79, 95 % CI: 1.44, 2.24), self-care (IRR: 1.25, 95 % CI: 1.08, 1.44) and household activities (IRR: 1.39, 95 % CI: 1.08, 1.78) after adjusting for previous falls and covariates. Multiple previous falls independently predicted limitations in mobility (IRR: 1.72, 1.30, 2.27), self-care (IRR: 1.40, 95 % CI: 1.19, 1.66) and household activities (IRR: 1.36, 95 % CI: 1.01, 1.83) after adjusting fear of falling and covariates. Conclusions: Fear of falling seems to be as important as multiple previous falls in terms of limiting older adults’ daily activities.

Objectives: This study aimed to evaluate the clinical value of ultrasound elastography in the differential diagnosis of benign and malignant cervical lesions and to compare the accuracy of the elasticity score and strain ratio in differentiating cervical lesions.Methods: B‐mode sonography and ultrasound elastography were performed on 84 cervical lesions (40 benign and 44 malignant) in 84 patients. All of the images were obtained transvaginally. The elasticity score was determined by a 5‐point scoring method. Calculation of the strain ratio was based on a comparison of the average strain measured in the lesion with the adjacent tissue of the same depth, size, and shape. The findings were compared with histopathologic results. With the use of receiver operating characteristic curves, the diagnostic value of the elasticity score and strain ratio methods was determined.Results: The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of the elasticity score in the differential diagnosis of cervical lesions were 81.8%, 85.0%, 83.3%, 85.7%, and 81.0%, respectively, whereas those of the strain ratio were 90.9%, 90.0%, 90.5%, 90.9%, and 90.0%. A strain ratio cutoff value of 4.525 was used as a standard to distinguish benign from malignant lesions. The strain ratio values of malignant lesions were much higher than those of benign lesions (range, 4.85–8.91 versus 0.62–4.50). The differences were statistically significant (P < .01).Conclusions: Ultrasound elastography is a promising technique that is easy and rapid to perform and can help identify cervical lesions that are likely to be malignant. It is obvious that the strain ratio yielded better results than the elasticity score. Both methods are semiquantitative, but quantification of the strain ratio is finer than that of the elasticity score.

Background: Subjective age refers to how young or old individuals experience themselves to be and is associated with health status, behavioral, cognitive, and biological processes that influence frailty. However, little research has examined the relationship between subjective age and frailty among older adults. This study examined the bidirectional association between subjective age and frailty among community-dwelling older adults. Methods: We used data from the 2011 to 2015 waves of the National Health and Aging Trends Study. Our sample consists of 2,592 community-dwelling older adults with complete data on main outcome variables. Subjective age was measured by asking participants, “What age do you feel most of the time?” Based on the five phenotypic criteria: exhaustion, unintentional weight loss, low physical activity, slow gait, and weak grip strength, frailty was categorized into robust = 0, pre-frailty = 1 or 2; frailty = 3 or more criteria met. Generalized estimating equation models were used to examine the concurrent and lagged association between subjective age and frailty. Results: Participants were, on average, 75.2 ± 6.8 years old, non-Hispanic whites (76 %), female (58 %). 77 % of the participants felt younger, 18 % felt the same, and 5 % felt older than their chronological age. About 45 %, 46 %, and 9 % of the participants were robust, pre-frailty and frailty in the first wave, respectively. Generalized estimating equations revealed that an “older” subjective age predicted a higher likelihood of pre-frailty and frailty (OR, 95 % CI = 1.93, 1.45–2.56). Conclusions: These findings suggest that people with older subjective age are more likely to be pre-frail/frail. Subjective age could be used as a quick and economical screening for those who are potentially frailty or at risk for frailty.

Background: The Chinese government is piloting canteen services for older adults, but few studies have explored the influence of canteen services on the health of these older adults. This study aimed to investigate the impact of canteen services on older adults’ general mental health, nutritional status, satisfaction with life, and social capital in rural areas. Methods: This study used a cross-sectional design. We selected 14 villages in Jinhua City, Zhejiang Province, China, including seven villages with canteen services and seven villages without canteen services. Participants were 284 senior older adults (aged 75~98), including 140 residing in villages with canteen services (Canteen Group [CG]) and 144 residing in villages without canteen services (Non-Canteen Group [NCG]). We also divided the CG into two sub-groups according to the funding sources (one receiving government support only, the other receiving government support plus enterprise donations). We used a self-designed questionnaire, including sociodemographics, diet-related items (e.g., satisfaction with the meals, diet expenditure, self-evaluation of meal nutrition), and the four scales including the Chinese version of the 12-item General Health Questionnaire (GHQ-12), the Chinese version of the Mini Nutritional Assessment Short-Form (MNA-SF), the Satisfaction with Life Scale (SWLS), and the Social Capital Questionnaire (SCQ). Results: The overall mental health, satisfaction with life, and social capital of the CG were better than the NCG (P < 0.05). The nutritional status of these two groups did not show a significant difference. Participants in the CG with financial support from local government and donations from an enterprise with a better dietary diversity exhibited a better nutritional status (P < 0.05); the average satisfaction with diet and self-evaluation of food nutrition of the CG were higher than the NCG (P < 0.05); the ratio of having a diet on time in the CG was higher than that of the NCG (P < 0.05). Conclusion: The free canteen services provided by the government can improve older adults’ satisfaction with life and diet, and mental health status and also enrich their social capital, but this still needs to be future evidenced. More financial support for canteen services is an essential component in promoting successful aging in China.
