Mixed methods research (MMR) is versatile, pragmatic, and adaptable to constraints and opportunities during a research process. Although MMR has gain popularity in health services management research, little is known about how the research approach has been used and the quality of research. We conducted a systematic review of 198 MMR articles published in selected U.S.-based and international health services management journals from 2000 through 2018 to examine the extent of MMR application and scientific rigor. Results showed limited, yet increasing, use of MMR and a high degree of correspondence between MMR designs and study purposes. However, most articles did not clearly justify using MMR designs and the reporting of method details and research integration were inadequate in a significant portion of publications. We propose a checklist to assist the preparation and review of MMR manuscripts. Additional implications and recommendations to improve transparency, rigor, and quality in MMR are discussed.

Background: COVID-19 has imposed challenges for older adults to access food, particularly in minority, lower income, and rural communities. However, the impact of COVID-19 on food access, diet quality, and nutrition of diverse older adult populations has not been systematically assessed.Objective: To examine changes in food access, diet quality, and nutritional status among older adults during the COVID-19 pandemic and the potential differential impacts of the COVID-19 pandemic on these nutrition-related outcomes using the framework of the socio-ecological model.Methods: An electronic search was conducted on 3 databases (PubMed, CINAHL, and Web of Science) on March 7, 2021. Original, peer-reviewed English-language studies published 10/1/2019–3/1/2021 were considered for which the mean age of participants was 50 years and older. In order to be considered, studies must have examined food access, food security, or nutrition constructs as an outcome.Results: The initial search yielded 13,628 results, of which 9,145 were duplicates. Of the remaining 4,483 articles, 13 articles were in scope and therefore selected in the final analysis, which can be characterized as descriptive (n = 5), analytical (n = 6), and correlational (n = 2). Studies were conducted among community-dwelling older adult populations (n = 7) as well as those temporarily residing in hospital settings (n = 6) in 10 countries. None of the in-scope studies examined the impact of food programs or specific public policies or disaggregated data by race/ethnicity.Conclusions: More research is needed to examine the impact of COVID-19 on food access/security and the differential barriers experienced by older adult populations.

This study identifies risk and protective factors for falls among older, community-dwelling African Americans. Drawing upon the biopsychosocial perspective (Engel, 1997), we conducted a series of sex- and age-adjusted multinomial logistic regression analyses to identify the correlates of fall events among older African Americans. Our sample consisted of 1,442 community-dwelling African Americans aged 65 and older, participating in the 2010-12 rounds of the Health and Retirement Study. Biophysical characteristics associated with greater relative risk of experiencing single and/or multiple falls included greater functional limitations, poorer self-rated health, poorer self-rated vision, chronic illnesses (high blood pressure, diabetes, cancer, lung disease, heart problems, stroke, and arthritis), greater chronic illness comorbidity, older age, and female sex. Physical activity was negatively associated with recurrent falls. Among the examined psychosocial characteristics, greater depressive symptoms were associated with greater relative risk of experiencing single and multiple fall events. Implications for clinicians and future studies are discussed.
