An App-Based Physical Activity Intervention in Community-Dwelling Chinese-, Tagalog-, and Vietnamese-Speaking Americans: Single-Arm Intervention Study. JMIR Form Res 2024; 8:e56373. [PMID: 38857065 DOI: 10.2196/56373] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2024] [Revised: 03/08/2024] [Accepted: 04/04/2024] [Indexed: 06/11/2024] Open
Abstract
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.

A population-based prospective cohort study in middle-aged and older adults of Amerindian ancestry living in rural Ecuador. Prev Med Rep 2022; 25:101668. [PMID: 34976705 PMCID: PMC8683764 DOI: 10.1016/j.pmedr.2021.101668] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2021] [Revised: 12/10/2021] [Accepted: 12/12/2021] [Indexed: 01/11/2023] Open
Abstract
Life's Simple 7 is an initiative of the American Heart Association developed for stratifying risk factors associated with adverse vascular outcomes and premature mortality. While this scale has been widely used, there is limited information on its applicability to individuals living in remote communities where risk factors and lifestyles differ from those found in urban settings. This longitudinal prospective study aimed to assess, according to the Life's Simple 7 scale, all-cause mortality in community-dwelling middle-age and older adults of Amerindian ancestry living in rural Ecuador. A total of 933 Atahualpa residents aged ≥ 40 years who received baseline interviews and procedures for measurement of cardiovascular health (CVH) metrics were enrolled and followed-up for a median of 8 years (interquartile range: 4-9 years). Using a Poisson regression model (adjusted for age at baseline, gender and the level of education), the predicted incidence rate of mortality was 4.22 per 100 person-years (95% C.I.: 2.48-5.97) for individuals with 0-1 CVH metrics in the ideal range, which decreased to 1.23 (95% C.I.: 0.24-2.21) for those with five ideal metrics. In an adjusted Cox-proportional hazard model that included all the CVH metrics, having three or more metrics in the ideal range significantly reduced the mortality hazard ratio when compared with individuals having 0-2 ideal metrics. Study results emphasize the usefulness of the Life's Simple 7 scale to estimate mortality risk in Amerindians living in remote communities. Control of CVH metrics should prove cost-effective for reducing premature deaths in underserved populations.

Abstract
Background In 2013, there was an estimation of greater than 4.5 million Afghan refugees who had migrated to the least developed countries. Over one million are legally registered in Iran. We assessed the heart health status as described by the American Heart Association (AHA) in the Afghan refugee populace. Methods This cross-sectional survey was carried out on 1,634 Afghan refugees, including 746 males (45.7%) and 888 females (54.3%), selected through a convenience sampling method in 2016. The American Heart Association's seven cardiovascular health metrics were evaluated to specify the status of heart health in Afghan refugees. Differences with age and sex were analyzed using the χ2 test. Results Only one (0.1%) participant met the ideal for all seven cardiovascular health metrics. No significant differences were found between women and men in meeting the ideal criteria for more than five cardiovascular health metrics. As age increased, the proportion of refugees who met the ideal for more than five cardiovascular health metrics declined. Conclusions Refugees were not meeting the ideal cardiovascular health for some of the assessed metrics. Intervention to improve and monitor heart health in Afghan refugees is needed.

Abstract
Metabolic syndrome (MetS) is a complex pathological state consisting of metabolic risk factors such as hypertension, insulin resistance, and obesity. The interconnectivity of cellular pathways within various biological systems suggests that each individual component of MetS may share common pathological sources. Additionally, MetS is closely associated with vasculopathy, including a reduction in microvessel density (MVD) (rarefaction) and elevated risk for various cardiovascular diseases. Microvascular impairments may contribute to perfusion-demand mismatch, where local metabolic needs are insufficiently met due to the lack of nutrient and oxygen supply, thus creating pathological positive-feedback loops and furthering the progression of disease. Sexual dimorphism is evident in these underlying cellular mechanisms, which places males and females at different levels of risk for cardiovascular disease and acute ischemic events. Estrogen exhibits protective effects on the endothelium of pre-menopausal women, while androgens may be antagonistic to cardiovascular health. This review examines MetS and its influences on MVD, as well as sex differences relating to the components of MetS and cardiovascular risk profiles. Finally, translational relevance and interventions are discussed in the context of these sex-based differences.

Abstract
Little is known about the dietary patterns of Chinese Americans. Understanding their dietary patterns can provide insights for addressing cardiovascular disease (CVD) risk among Chinese American immigrants. The objective of this study was to identify dietary patterns among Chinese American immigrants living in New York City (NYC) and to describe associations with demographic and CVD risk factors. A validated Food Frequency Questionnaire assessed usual dietary intake in Chinese American immigrants living in NYC as part of the Chinese American Cardiovascular Health Assessment (CHA CHA) in 2010-2011 (n = 1973, age range 21-89 years). Principal components analysis with varimax rotation retaining three factors with eigenvalues > 1.5 identified dietary patterns. Multivariable linear regression models tested associations between CVD risk factors and dietary pattern scores. In multivariable analyses, each unit of increase in the Sweets factor was associated with 0.76 ± 0.33 (mean ± SD) mg/dL higher HDL cholesterol and a 6.2 ± 2.7% increase in HOMA-IR. In contrast, each unit increase in the Fried Noodles factor was associated with a 0.27 ± 0.11 inch greater waist circumference, - 0.89 ± 0.40 mg/dL lower HDL cholesterol, and also a 6.9 ± 2.6% increase in HOMA-IR. Each unit increase in the Vegetables factor was associated with a - 1.40 ± 0.43 mmHg and - 0.95 ± 0.27 mm Hg decrease in systolic and diastolic blood pressure, respectively. Dietary patterns are significantly associated with CVD risk factors among Chinese American immigrants in NYC. Future work will inform how dietary patterns relate to level of acculturation in order to guide the development of dietary interventions to reduce CVD risk.

A Study of Physical Activity Determinants among High-Risk Hypertensive Filipino and Korean Americans. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:ijerph16071156. [PMID: 30935110 PMCID: PMC6479917 DOI: 10.3390/ijerph16071156] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/28/2019] [Revised: 03/27/2019] [Accepted: 03/27/2019] [Indexed: 01/24/2023]
Abstract
Physical activity (PA) serves a critical role in maintaining health and preventing chronic diseases, though its influence on high-risk Asian American populations is unclear. The purpose of this study was to determine PA levels among Filipino and Korean Americans at high risk of hypertension and to identify sociodemographic and health-related factors associated with PA levels in these populations. A cross-sectional survey was administered to 137 participants in the Greater Philadelphia Area. Data was collected on PA levels, sociodemographic factors, and health factors. Multinomial logistic regression was conducted to determine predictors associated with low, moderate, and high PA and predictive probabilities were calculated for interaction terms, incorporating ethnicity and blood pressure variables. Overall, 42.33% of participants belonged to the moderately active PA group and 21.90% belonged to the highly active group. In the final multinomial regression model, it was found that having gone to college increased the odds of being in the moderately active PA group (coef. = 1.96, p = 0.034), while having high blood pressure reduced the odds of being in the moderately active PA group (coef. = -2.21, p = 0.022). Lastly, being Korean versus Filipino reduced the odds of being in the highly active category (coef. = -2.89, p = 0.035). Based on predictive probabilities, Koreans and Filipinos with high blood pressure were more likely to belong in the low active PA category (52.31% and 46.33%). These findings highlight the need for culturally relevant PA interventions for promoting and increasing PA levels to prevent and manage hypertension among these populations.
