Efficacy of a Community Health Worker-Based Intervention in Improving Dietary Habits Among Community-Dwelling Older People: A Controlled, Crossover Trial in Japan

Community health workers' perspectives on integrating into school settings to support student health

Introduction

While schools represent key venues for supporting health, they continue to experience gaps in health resources. The integration of community health workers (CHWs) into schools has the potential to supplement these resources but has been underexplored. This study is the first to examine perspectives of experienced CHWs about how CHWs can be applied in school settings to support student health.

Methods

This qualitative study involved conducting semi-structured interviews focused on implementation of CHWs in schools with individuals who held positions aligned with the CHW scope of work. De-identified transcripts were analyzed, and codes were organized into domains and themes.

Results

Among 14 participants, seven domains emerged about the implementation of CHWs in schools: roles and responsibilities, collaborations, steps for integration, characteristics of successful CHWs, training, assessment, and potential challenges. Participants shared various potential responsibilities of school-based CHWs, including educating on health topics, addressing social determinants of health, and supporting chronic disease management. Participants emphasized the importance of CHWs building trusting relationships with the school community and identified internal and external collaborations integral to the success of CHWs. Specifically, participants indicated CHWs and schools should together determine CHWs' responsibilities, familiarize CHWs with the school population, introduce CHWs to the school community, and establish support systems for CHWs. Participants identified key characteristics of school-based CHWs, including having familiarity with the broader community, relevant work experience, essential professional skills, and specific personal qualities. Participants highlighted trainings relevant to school-based CHWs, including CHW core skills and health topics. To assess CHWs' impact, participants proposed utilizing evaluation tools, documenting interactions with students, and observing indicators of success within schools. Participants also identified challenges for school-based CHWs to overcome, including pushback from the school community and difficulties related to the scope of work.

Discussion

This study identified how CHWs can have a valuable role in supporting student health and the findings can help inform models to integrate CHWs to ensure healthy school environments.

Study protocol for a pragmatic cluster randomized controlled trial to improve dietary diversity and physical fitness among older people who live at home (the "ALAPAGE study")

BACKGROUND

Diet and physical activity are key components of healthy aging. Current interventions that promote healthy eating and physical activity among the elderly have limitations and evidence of French interventions' effectiveness is lacking. We aim to assess (i) the effectiveness of a combined diet/physical activity intervention (the "ALAPAGE" program) on older peoples' eating behaviors, physical activity and fitness levels, quality of life, and feelings of loneliness; (ii) the intervention's process and (iii) its cost effectiveness.

METHODS

We performed a pragmatic cluster randomized controlled trial with two parallel arms (2:1 ratio) among people ≥60 years old who live at home in southeastern France. A cluster consists of 10 people participating in a "workshop" (i.e., a collective intervention conducted at a local organization). We aim to include 45 workshops randomized into two groups: the intervention group (including 30 workshops) in the ALAPAGE program; and the waiting-list control group (including 15 workshops). Participants (expected total sample size: 450) will be recruited through both local organizations' usual practices and an innovative active recruitment strategy that targets hard-to-reach people. We developed the ALAPAGE program based on existing workshops, combining a participatory and a theory-based approach. It includes a 7-week period with weekly collective sessions supported by a dietician and/or an adapted physical activity professional, followed by a 12-week period of post-session activities without professional supervision. Primary outcomes are dietary diversity (calculated using two 24-hour diet recalls and one Food Frequency Questionnaire) and lower-limb muscle strength (assessed by the 30-second chair stand test from the Senior Fitness Test battery). Secondary outcomes include consumption frequencies of main food groups and water/hot drinks, other physical fitness measures, overall level of physical activity, quality of life, and feelings of loneliness. Outcomes are assessed before the intervention, at 6 weeks and 3 months later. The process evaluation assesses the fidelity, dose, and reach of the intervention as its causal mechanisms (quantitative and qualitative data).

DISCUSSION

This study aims to improve healthy aging while limiting social inequalities. We developed and evaluated the ALAPAGE program in partnership with major healthy aging organizations, providing a unique opportunity to expand its reach.

Group-based nutrition interventions to promote healthy eating and mobility in community-dwelling older adults: a systematic review

OBJECTIVE

To identify the efficacy of group-based nutrition interventions to increase healthy eating, reduce nutrition risk, improve nutritional status and improve physical mobility among community-dwelling older adults.

DESIGN

Systematic review. Electronic databases MEDLINE, CINAHL, EMBASE, PsycINFO and Sociological Abstracts were searched on July 15, 2020 for studies published in English since January 2010. Study selection, critical appraisal (using the Joanna Briggs Institute's tools) and data extraction were performed in duplicate by two independent reviewers.

SETTING

Nutrition interventions delivered to groups in community-based settings were eligible. Studies delivered in acute or long-term care settings were excluded.

PARTICIPANTS

Community-dwelling older adults aged 55+ years. Studies targeting specific disease populations or promoting weight loss were excluded.

RESULTS

Thirty-one experimental and quasi-experimental studies with generally unclear to high risk of bias were included. Interventions included nutrition education with behaviour change techniques (BCT) (e.g. goal setting, interactive cooking demonstrations) (n 21), didactic nutrition education (n 4), interactive nutrition education (n 2), food access (n 2) and nutrition education with BCT and food access (n 2). Group-based nutrition education with BCT demonstrated the most promise in improving food and fluid intake, nutritional status and healthy eating knowledge compared with baseline or control. The impact on mobility outcomes was unclear.

CONCLUSIONS

Group-based nutrition education with BCT demonstrated the most promise for improving healthy eating among community-dwelling older adults. Our findings should be interpreted with caution related to generally low certainty, unclear to high risk of bias and high heterogeneity across interventions and outcomes. Higher quality research in group-based nutrition education for older adults is needed.

Tailoring First Aid Courses to Older Adults Participants

Relevant organizations emphasize the importance of first aid (FA) for older adults due to the increased risk of injuries and sudden illnesses in old age. Even though FA training guidelines have been developed, no program for an FA course adapted for the older adults has been formally adopted in Europe. This study’s objective is to identify older adults’ needs, beliefs, desires, advantages, and possible limitations in connection with FA. This qualitative study used semistructured interviews with 22 laypersons and retired health professionals older than 60 years old. The qualitative content analysis indicated that the major themes elicited by the older adults are motivation to participate in the FA training, older adults’ specific features as a resource or obstacle for participating in FA training, general suggestions, and content suggestions for FA training. Older adults are very differently motivated to participate in FA training due to the heterogeneity of their psychophysical abilities. They need and want to obtain additional knowledge from the field of FA and health protection for which any psychophysical limitations are not as relevant as when learning cardiopulmonary resuscitation. They want to learn how to recognize emergency situations and more about calling emergency services with the use of modern technology. In addition to cardiopulmonary resuscitation without rescue breaths, they also want to learn about topics related to the treatment of injuries. Those who had practiced FA in their work–life think that they can be a good source to transfer their knowledge to persons from their generation. While planning an FA training course, it has to be taken into consideration that older adults want a short course, adjusted to their varied psychophysical abilities. Due to the wide array of contents they want to learn, it would be reasonable to prepare a selection of different programs for short training courses.
