Promoting weight-loss maintenance among Black women primary care patients: A cluster RCT of a culturally sensitive versus standard behavioural approach

A Cluster-Randomized Study of Technology-Assisted Health Coaching for Weight Management in Primary Care

PURPOSE

We undertook a trial to test the efficacy of a technology-assisted health coaching intervention for weight management, called Goals for Eating and Moving (GEM), within primary care.

METHODS

This cluster-randomized controlled trial enrolled 19 primary care teams with 63 clinicians; 9 teams were randomized to GEM and 10 to enhanced usual care (EUC). The GEM intervention included 1 in-person and up to 12 telephone-delivered coaching sessions. Coaches supported goal setting and engagement with weight management programs, facilitated by a software tool. Patients in the EUC arm received educational handouts. We enrolled patients who spoke English or Spanish, were aged 18 to 69 years, and either were overweight (body mass index 25-29 kg/m2) with a weight-related comorbidity or had obesity (body mass index ≥30 kg/m2). The primary outcome (weight change at 12 months) and exploratory outcomes (eg, program attendance, diet, physical activity) were analyzed according to intention to treat.

RESULTS

We enrolled 489 patients (220 in the GEM arm, 269 in the EUC arm). Their mean (SD) age was 49.8 (12.1) years; 44% were male, 41% Hispanic, and 44% non-Hispanic Black. At 12 months, the mean adjusted weight change (standard error) was -1.4 (0.8) kg in the GEM arm vs -0.8 (1.6) kg in the EUC arm, a nonsignificant difference (P = .48). There were no statistically significant differences in secondary outcomes. Exploratory analyses showed that the GEM arm had a greater change than the EUC arm in mean number of weekly minutes of moderate to vigorous physical activity other than walking, a finding that may warrant further exploration.

CONCLUSIONS

The GEM intervention did not achieve clinically important weight loss in primary care. Although this was a negative study possibly affected by health system resource limitations and disruptions, its findings can guide the development of similar interventions. Future studies could explore the efficacy of higher-intensity interventions and interventions that include medication and bariatric surgery options, in addition to lifestyle modification.

Bridging health self-efficacy and patient engagement with patient-centered culturally sensitive health care for Black American adults

This study investigates whether systems-level interventions, specifically patient-centered culturally sensitive health care (PC-CSHC) from healthcare providers, office staff, and the clinic environment, moderate the relationship between health self-efficacy and patient engagement among Black American adults. An online survey was completed by 198 Black American adults. PC-CSHC from healthcare providers, office staff, and the clinic environment did not mitigate the adverse effects of low health self-efficacy on patient engagement. However, PC-CSHC from healthcare providers (b = 0.38) was as significant as health self-efficacy (b = 0.37) in predicting patient engagement, R2 = 0.47, F(9, 177) = 19.61, p < 0.001. Provider-delivered PC-CSHC can enhance patient engagement among Black American adults. This systems-level approach has the potential to reach more patients than intrapersonal interventions alone and alleviates the undue burden placed on Black Americans to leverage intrapersonal strengths in the face of health disparities rooted in structural racism.

Health promotion intervention delivered by trained community health workers (CHWs) for obesity prevention and control among adult people: a scoping review protocol

INTRODUCTION

Obesity is one of the most common diseases and is the main risk factor for the occurrence of other non-communicable diseases, such as hypertension, diabetes, heart disease and cancer. Obesity can be prevented and controlled, especially by adopting healthy behaviours, such as increased physical activity and healthy dietary patterns. The delivery of health promotion interventions by trained community health workers (CHWs) can be applied to obesity prevention and control based on the culture and local context. Our study aimed to map the health promotion interventions delivered by trained CHWs in the context of obesity prevention and control in community settings.

METHODS

This scoping review (ScR) was conducted using the methodologies introduced by Arksey and O'Malley. The search strategy was conducted on electronic databases, such as MEDLINE via PubMed, Scopus, Cochrane, ProQuest, medRxiv and Clinicaltrial.gov, from 2010 until 2022 by entering the appropriate keywords. Afterwards, the title, abstract and full text were screened independently by two researchers in accordance with the inclusion and exclusion criteria. Then, the data were charted, extracted, collated, summarised and reported.

ETHICS AND DISSEMINATION

In this ScR, research ethics was unnecessary because this work synthesised evidence from pre-existing literature only. The results of this ScR were published in peer-reviewed journals and presented at scientific conferences. We disseminated the results using graphs, images, tables, discussions and a plain language summary.
