[Construct validity in structural perspectives of the Questionnaire for medical checkup of old-old among community-dwelling older adults: A pilot study of a countermeasure against COVID-19].

AIM: This study aimed to clarify the construct validity of the Questionnaire for medical checkup of old-old (QMCOO). METHODS: In this cross-sectional study, questionnaires including the QMCOO were distributed to 1,953 older adults, and responses were returned by mail. We conducted an exploratory factor analysis (EFA) for the QMCOO among older participants (age ≥75 years) and extracted the relevant factors. Next, we structured the model for the QMCOO based on these factors and conducted a confirmatory factor analysis (CFA) using structural equation modeling. We conducted a CFA among young-older participants (age 65 to <75 years) for the same model. RESULTS: Of the 1,110 (53.5%) adults who responded, data from the 994 respondents who provided complete answers were analyzed. Five factors were extracted from the results of the EFA: physical and mental condition, relationship with society, eating and smoking, chance for exercise, and cognitive function. The results of the CFA were as follows: comparative fit index (CFI) = 0.899, adjusted goodness of fit index (AGFI) = 0.965, root mean square error of approximation (RMSEA) = 0.034, and standardized root mean square residual (SRMR) = 0.040. Meanwhile, the results for young-older participants were as follows: CFI = 0.886, AGFI = 0.942, RMSEA = 0.035, and SRMR = 0.048. CONCLUSIONS: The QMCOO assessed health condition and was composed of multiple factors associated with frailty. The CFA results indicated that the model fit was good. The QMCOO showed sufficient structural validity. Therefore, the construct validity of the QMCOO was shown.

Change in static standing balance ability of community-residing elderly females after the onset of COVID-19 pandemic in Japan.

[Purpose] This study aimed to examine the changes in the balance ability of community-residing elderly females between 2017 and 2020. [Participants and Methods] The participants included 202 females with ≥65 years of age (average age, 78.3 ± 5.88 years), living independently in the community and attending the salon. The balance ability was measured through a one-legged standing test by keeping the participants' eyes open. The measurement duration was a maximum of 120 s while standing still. Each participant underwent the measurement twice, and the best attempt was recorded. The survey period was from 2017 to 2020, and the measurements were conducted once a year. [Results] The 2020 records showed a statistically significant difference compared to those of the other 3 years. The degree of decline was higher in the old-old than that in the young-old. [Conclusion] The balance ability of the elderly females was found to reduce significantly during the COVID-19 pandemic. Specifically, supporting physical activities in the old-old females is necessary to improve their balance ability.

Lifestyle Modification Program on a Metabolically Healthy Elderly Population with Overweight/Obesity, Young-Old vs. Old-Old. CONSEQUENCES of COVID-19 Lockdown in This Program.

The SARS-CoV-2 pandemic led to lockdowns, which affected the elderly, a high-risk group. Lockdown may lead to weight gain due to increased food intake and reduced physical activity (PA). Our study aimed to analyze the impact of a 12-month lifestyle intervention on a metabolically healthy overweight/obese elderly (MHOe) population and how the lockdown by COVID-19 affected this program. Methods: MHOe participants (65-87 years) were recruited to participate in a lifestyle modification intervention based on the Mediterranean diet (MedDiet) and regular PA. Participants were classified into two groups: young-old (<75 years) or old-old (≥75 years). Anthropometric and clinical characteristics, energy intake, and energy expenditure were analyzed at baseline and after 12 months of intervention. Results: The final sample included 158 MHOe participants of both sexes (age: 72.21 ± 5.04 years, BMI: 31.56 ± 3.82 kg/m2): 109 young-old (age: 69.26 ± 2.83 years, BMI: 32.0 ± 3.85 kg/m2) and 49 old-old (age: 78.06 ± 2.88 years, BMI: 30.67 ± 3.64 kg/m2). After 12 months of intervention and despite lockdown, the young-old group increased MedDiet adherence (+1 point), but both groups drastically decreased daily PA, especially old-old participants. Fat mass significantly declined in the total population and the young-old. Depression significantly increased (26.9% vs. 21.0%, p < 0.0001), especially in the old-old (36.7% vs. 22.0%, p < 0.0001). No significant changes were found in the glycemic or lipid profile. Conclusions: This study indicates that ongoing MedDiet intake and regular PA can be considered preventative treatment for metabolic diseases in MHOe subjects. However, mental health worsened during the study and should be addressed in elderly individuals.
