Article Synopsis
  • Interventions targeting social needs like low income and housing instability are becoming more common in healthcare, but evidence on how to effectively implement these interventions on a larger scale is scarce.
  • The objective of the study was to evaluate the intensity and complexity of social needs interventions in randomized clinical trials (RCTs) and to determine if these trials measure the interventions' causal effects on health outcomes.
  • The review found 77 relevant RCTs involving over 135,000 participants, with most studies showing high intensity and complexity features, indicating a need for more thorough evaluation of their impacts.

Latina women have a high prevalence of obesity and obesity-related chronic diseases, such as diabetes. Approximately half of Latinas with obesity will also experience food insecurity, or a lack of access to enough food for an active and healthy life. Food insecurity is a barrier for effective prevention and management of obesity-related chronic diseases.

Engagement marketing, when applied to increasing the social good, involves making a deliberate effort to engage communities with an organization's brand that might not have otherwise happened organically. Organizations that typically focus on increasing the social good include non-profits, community organizations, public health departments, and federal, state, and local agencies. Engagement marketing builds relationships, gives a voice to, and fosters collaboration with community members to transform their insights into impactful experiences that motivate and empower them to act to increase the social good.

Introduction: Young women in sub-Saharan Africa account for two-thirds of all new HIV infections and face high rates of unintended pregnancy. Multipurpose prevention technologies (MPTs) are promising products under development that are designed to simultaneously prevent HIV and unintended pregnancy. Since MPTs will be used in the context of sexual relationships, ensuring acceptability and use requires understanding the role of male partners in MPT use decision-making.

Background: Positive Health Check is an evidence-based video doctor intervention developed for improving the medication adherence, retention in care, and viral load suppression of people with HIV receiving clinical care.

Setting: Four HIV primary care clinics within the United States.

Methods: As part of a type 1 hybrid trial, a mixed-methods approach was used to longitudinally assess the following 3 key implementation constructs over a 23-month period: innovation-values fit (ie, the extent to which staff perceive innovation use will foster the fulfillment of their values), organizational readiness for change (ie, the extent to which organizational members are psychologically and behaviorally prepared to implement organizational change), and implementation climate (ie, the extent to which implementation is expected, supported, and rewarded).

Background: Although Latino men have the highest prevalence (45%) of obesity among all men in the United States, traditional weight loss interventions have not effectively engaged this hard-to-reach and diverse group. Offering choices among technology-mediated weight loss interventions may offer advantages.

Objective: The aim of this study is to examine Latino men's preferences among 3 weight loss intervention options.

Background: Depression exerts a staggering toll that is worsened with co-occurring chronic conditions such as obesity. It is imperative to develop more effective interventions for depression and to identify objective and biological plausible neural mechanisms to understand intervention outcomes. The current study uses functional neuroimaging to determine whether a behavioural intervention changes the negative affect circuit and whether these changes relate to subsequent improvements in both symptom and problem-solving outcomes in depressed patients with co-occurring obesity.

Unlabelled: The COVID-19 pandemic has highlighted existing crises and introduced new stressors for various populations. We suggest that a multilevel ecological perspective, one that researchers and practitioners have used to address some of public health's most intransigent challenges, will be necessary to address emotional distress and mental health problems resulting from the COVID-19 pandemic. Multiple levels of influence (individual, interpersonal, organizational, community, and policy) each contribute (individually and in combination) to population health and individual well-being.
