A Cluster Randomized Controlled Trial of a Lay Health Worker Intervention to Increase Healthy Eating and Physical Activity Among Vietnamese Americans

An App-Based Physical Activity Intervention in Community-Dwelling Chinese-, Tagalog-, and Vietnamese-Speaking Americans: Single-Arm Intervention Study

BACKGROUND

Physical inactivity is associated with adverse health outcomes among Asian Americans, who exhibit the least adherence to physical activity guidelines compared with other racial and ethnic groups. Mobile app-based interventions are a promising approach to promote healthy behaviors. However, there is a lack of app-based interventions focused on improving physical activity among Asian Americans whose primary language is not English.

OBJECTIVE

This pilot study aimed to assess the feasibility and acceptability of a 5-week intervention using a culturally and linguistically adapted, evidence-based mobile phone app with an accelerometer program, to promote physical activity among Chinese-, Tagalog-, or Vietnamese-speaking Americans.

METHODS

Participants were recruited through collaborations with community-based organizations. The intervention was adapted from a 12-month physical activity randomized controlled trial involving the app and accelerometer for English-speaking adults. Sociodemographic characteristics, lifestyle factors, and physical measurements were collected at the baseline visit. A 7-day run-in period was conducted to screen for the participants who could wear a Fitbit One (Fitbit LLC) accelerometer and complete the app's daily step diary. During the 4-week intervention period, participants wore the accelerometer and reported their daily steps in the app. Participants also received daily messages to reinforce key contents taught during an in-person educational session, remind them to input steps, and provide tailored feedback. Feasibility measures were the percentage of eligible participants completing the run-in period and the percentage of participants who used the app diary for at least 5 out of 7 days during the intervention period. We conducted poststudy participant interviews to explore overall intervention acceptability.

RESULTS

A total of 19 participants were enrolled at the beginning of the study with a mean age of 47 (SD 13.3; range 29-70) years, and 58% (n=11) of them were female. Of the participants, 26% (n=5) were Chinese, 32% (n=6) were Vietnamese, and 42% (n=8) were Filipino. All participants met the run-in criteria to proceed with the intervention. Adherence to the app diary ranged from 74% (n=14) in week 2 to 95% (n=18) in week 4. The daily average steps per week from accelerometers increased each week from 8451 (SD 3378) steps during the run-in period to 10,930 (SD 4213) steps in week 4. Participants reported positive experiences including an increased motivation to walk and the enjoyment of being able to monitor their physical activity.

CONCLUSIONS

This is the first pilot study of a multicomponent intervention and evidence-based mobile phone app to promote physical activity among Asian Americans who use apps in traditional Chinese, Tagalog, or Vietnamese, which demonstrated high feasibility and acceptability. Future work focused on multilingual mobile apps to address disparities in physical inactivity among Asian Americans should be considered.

Promoting Physical Activity Among Immigrant Asian Americans: Results from Four Community Health Worker Studies

Racial/ethnic minorities have demonstrated lower rates of physical activity (PA) than non-Hispanic Whites. This study examined outcomes in PA measures after participation in a community health worker (CHW) intervention. We performed a secondary data analysis from four randomized controlled trials utilizing CHWs (n = 842) in New York City (Bangladeshi-diabetes management, Filipino-hypertension management, and Korean and Asian Indian-diabetes prevention). Outcomes included total weekly PA, PA self-efficacy, PA barriers, and PA social interaction. Each measure was examined at baseline and study endpoint. Generalized estimating equation models were fitted to assess the repeated measures over time, while accounting for study group and socio-demographic factors. Moderate PA, recommended PA, and self-efficacy increased significantly among treatment group participants. PA social interaction increased significantly among Filipinos and Asian Indians. In adjusted regression analysis, time x group interaction was significant for all PA outcomes except for PA barriers. Culturally-adapted lifestyle interventions may potentially improve PA-related outcomes in Asian immigrant communities. Trial registration at ClinicalTrials.gov includes: NCT03530579 (RICE Project), NCT02041598 (DREAM Project), and NCT03100812 (AsPIRE).

The Effectiveness of Language-Specific Personal Care Education on Improving the Knowledge and Skills of Vietnamese American In-Home Supportive Service Caregivers

BACKGROUND

In-Home Supportive-Services (IHSS) caregivers provide personal care assistance to low-income older adults. According to the California Social Service Department, 20.2% of IHSS caregivers spoke Vietnamese in one county. The purpose of this project was to improve the knowledge and skills among these Vietnamese American caregivers by providing a language-specific and culturally appropriate education on personal care.

METHODS

The project used a pre- and post-test design. Under the guidance of nursing faculty, four Vietnamese-speaking nursing students provided a 2-hr educational program on personal care (e.g., bathing, oral care) to registered Vietnamese IHSS caregivers. A pre- and post-survey was conducted.

RESULTS

Overall, 55 caregivers completed the surveys. The surveys showed significant increases in confidence in knowledge and skills related to personal care topics (all ps < .001).

CONCLUSION

The findings demonstrated that the cultural and language-specific education was effective in increasing knowledge and confidence of Vietnamese IHSS caregivers related to personal care for older adults.

Effects of behavioral change techniques on diet and physical activity in colorectal cancer patients: a systematic review and meta-analysis

PURPOSE

To investigate the effect of behavior change technology on diet, exercise, and sedentary behaviors in colorectal cancer over the last decade.

METHODS

This study systematically searched six English databases (Cochrane Library, EMBASE, APA PsycInfo, SCOPUS, PubMed, Web of Science) and three Chinese databases (CNKI, WanFang, and SINOMEd), searched for eligible clinical trials published between January 1, 2012, and December 31, 2021. Each database follows the principle of PICOS and adopts the method of subject words combined with free words to conduct literature retrieval, such as "colorectal cancer" and "behavior change intervention." Meta-analysis was performed using RevMan 5.3 software. Continuous data using the same measurement tools were analyzed using weighted mean difference (MD). Otherwise, standard mean difference (SMD) was used for analysis. The confidence interval is 95%. There was no significant statistical heterogeneity between the studies (P > 0.1, I² < 50%), and fixed-effects model was used. There was statistical heterogeneity (P ≤ 0.1), I² ≥ 50%), and the random effects model was used for analysis. The Cochrane risk of bias tool was used to assess the risk of bias in the included studies.

RESULTS

In total, 15 good-quality randomized controlled trials were identified. Six studies focused on eating habits. Twelve studies focused on physical activity. We found that behavior change techniques had significant effects on colorectal cancer survivors' eating behaviors such as frequency of fruit and vegetable intake and mastery of dietary knowledge (P < 0.05). The meta-analysis showed that the amount of physical activity in the intervention group increased by 71.76 min/w (16.27 to 127.24, P = 0.01) at 3 months after treatment compared with the control group. The meta-analysis showed that the amount of physical activity in the intervention group increased by 113.97 min/w (48.34 to 179.59, P < 0.001) at 6 months after treatment compared with the control group. The results revealed significant difference in the overall effect of the behavior change technique on the amount of exercise. Behavior change techniques were not found to have significant effects on body weight and BMI in colorectal cancer survivors, but it had a significant effect on sedentary behavior (P < 0.05).

CONCLUSIONS

The effects of behavioral change technique intervention on diet and physical activity may be more clinically significant at 6 months. This is the first systematic review and meta-analysis to summarize the effectiveness of a behavioral change techniques health behavior intervention in patients with colorectal cancer.

Evaluation of an Online Course Promoting Health and Wellbeing for University Students and Employees

Published studies dealing with health promotion activities, such as the improvement of physical activity and healthy eating, for workers and students prove the effectiveness of these preventive interventions. The consequent benefits include better prevention of cardiovascular risk and an improvement in quality of life. Considering this, an intervention aimed at promoting healthy eating and non-sedentary lifestyles has been implemented within an Italian university: the aim of the present research is to evaluate its effectiveness. The intervention consisted of a targeted asynchronous e-learning two-hour course on healthy eating and non-sedentary lifestyles. The attendants were 2004 university students and employees. We conducted two surveys before and after the training intervention, and, through the responses obtained, we evaluated the effectiveness of the intervention. We applied different statistical methods, including unpaired t-tests and nonparametric tests, principal components and cluster analysis. Our results indicate that the post-training knowledge has been significantly improved, compared to that pre-training (7.3 vs. 8.7, p < 0.001). Moreover, the whole sample showed an improved awareness of the importance of healthy behaviors, and perception of the University as an institution promoting a healthy lifestyle. Through the principal components analysis, we identified a unidimensional latent factor named “health and behaviors”. The cluster analysis highlighted that the sub-group reporting the lowest scores at the survey before the training was the one with the highest improvement after the intervention. To the best of our knowledge, this is the first Italian study testing, before and after a health promotion intervention, the knowledge and the attitudes and behaviors towards healthy lifestyles of a group of students and workers. Moreover, we also evaluated the pre- and post-intervention perceived health status, as well as the level of engagement of the attendants, with respect to their colleagues and management in an educational institution promoting wellbeing. The conclusions of our study support the need for further adoption of health promotion training interventions, similar to the one we performed, in order to improve healthy eating and non-sedentary behaviors among workers and students.

The design and impact of culturally-safe community-based physical activity promotion for immigrant women: descriptive review

BACKGROUND

Immigrant women have low rates of physical activity (PA), placing them at risk for chronic diseases. Some research suggests that strategies targeting this group must be culturally-safe and community-based. This study aimed to identify the design (i.e. characteristics) and impact of culturally-safe community-based PA promotion for immigrant women.

METHODS

We conducted a descriptive review by searching MEDLINE, EMBASE, SPORTDiscus, CINAHL, SCOPUS, Cochrane Library and Joanna Briggs Institute Database of Systematic Reviews from inception to June 9, 2021 for English language studies that assessed community-based PA promotion strategies targeting adult immigrants and involved at least 50% women. We compiled findings in a preliminary context-mechanisms-outcomes conceptual framework.

RESULTS

We included 13 studies published from 2004 to 2020. Three included women-only; the remainder included a median of 63% women (range 50 to 98%). Studies included immigrants from Brazil, Dominican, Columbian, Haiti, Mexico, China, Vietnam, Bangladesh, India, Pakistan, Somalia, Sudan and Turkey. All but one study (89%) significantly improved one or more outcomes: PA knowledge, PA participation and anthropometric measures (e.g. weight, BMI, blood pressure). Most (89%) strategies were multi-faceted: in-person group educational sessions reinforced by take-home educational material and/or follow-up reminder phone calls. Single strategies (e.g. mailed educational material, group educational session) also achieved beneficial outcomes. We identified 17 culturally-safe characteristics of PA promotion strategies: language of choice, based in community settings or organizations, led by lay health workers, reflected ethno-cultural linguistic expressions and PA norms, and recognized and offered solutions to barriers of PA. Findings were captured in a preliminary theory of how contextual factors (gender, intersectionality) and mechanism (culturally-safe PA promotion) may influence PA-related outcomes (PA knowledge, self-efficacy and participation; anthropometric measures, quality of life).

CONCLUSIONS

This study revealed the characteristics of PA promotion strategies that significantly improved PA-related outcomes among immigrants. Given that few studies focused solely on immigrant women or reported sub-analyses, the conceptual framework generated by this study can be used in future research to more definitively establish the design and impact of culturally-safe, community-based PA promotion for immigrant women.

Heart-Healthy Integrative Nutritional Counseling Group Education Sessions Among Chinese Americans With Cardiovascular Risk Factors or Disease: A Primary Care Quality Improvement Pilot

PURPOSE

Current biomedical cardiovascular disease nutrition counseling does not incorporate Chinese medicine principles.

METHODS

A heart-healthy integrative nutritional counseling (H2INC) curriculum consistent with Chinese medicine principles and biomedical nutrition guidelines was taught to Chinese Americans in group education sessions. Chinese-speaking patients with cardiovascular disease or risk factors from an urban general medicine practice were recruited to attend a 90-minute group session. Participants completed pre-post surveys to assess the impact of H2INC on their perceived heart-healthy nutrition knowledge and empowerment, as well as the cultural relevance of H2INC.

RESULTS

A total of 47 participants (mean age: 74 years; 63.8% female) attended a session. In response to the statement "I am able to choose heart-healthy Chinese foods to eat," on a 5-point Likert scale for which "strongly disagree" = 1 and "strongly agree" = 5, the presession survey mean response was 3.87 ± 0.69 and the postsession survey mean response was 4.13 ± 0.58 (P=0.05). Postsession, 87% of participants agreed or strongly agreed that they felt confident using what they learned and 94% agreed or strongly agreed that H2INC fit their culture.

CONCLUSIONS

H2INC had a positive impact on perceived heart-healthy nutrition knowledge and empowerment and rated high in cultural relevance. Culturally relevant education sessions like H2INC could be a promising primary care health education intervention.
