Why do some people with osteoarthritis and obesity awaiting hip or knee arthroplasty achieve successful weight management? A qualitative study. | LitMetric

AI Article Synopsis

Article Abstract

Aim: To explore perceived barriers and enablers to weight management among people with obesity awaiting total knee or hip arthroplasty.

Design: A nested qualitative study within a multi-centre, quasi-experimental pilot study comparing usual care weight management to a dietitian-led weight-loss diet.

Methods: Semi-structured individual interviews were conducted with adults with end-stage osteoarthritis and a body mass index ≥30 kg/m waitlisted for primary total knee or hip arthroplasty. Participants with diverse sociodemographic characteristics and varied success with weight management in the pilot study were purposively sampled. Interviews were analysed using inductive thematic analysis, underpinned by constructivist-interpretivist epistemology. The Patient Activation Measure and Health Literacy Questionnaire were used for context when interpreting the findings.

Results: Twenty-five participant interviews were conducted with a sociodemographically varied sample (aged 44-80 years, 9 born in Australia, 6 in paid employment and 11 lost ≥5% of their baseline weight). Four identified themes underpinned successful weight management: beliefs, adaptability, navigating healthcare and sociocultural context. Beliefs about whether weight was perceived as a problem, the expectation of weight loss and treatment-related beliefs influenced participants' perspectives towards weight loss. Adaptability, the ability to overcome barriers to weight loss, comprised three subthemes; readiness to act, degree of independence and problem-solving skills. Approaches towards navigating healthcare influenced uptake and adherence to weight management recommendations. Importantly, these themes were dependent on social and environmental circumstances, which influenced the type of barriers experienced and resources available to the individual.

Conclusion: Differences in a person's beliefs, their ability to adapt and navigate healthcare and sociocultural context appear to explain successful weight management among people with end-stage arthritis.

Implications For The Profession And/or Patient Care: Clinicians should allow for individualisation cognisant of the identified themes when providing advice and treatment to promote adherence to weight management interventions.

Impact: This study explored perceived barriers and enablers to weight management among people with obesity awaiting total knee or hip arthroplasty. Four identified themes underpinned successful weight management: beliefs, adaptability, navigating healthcare and sociocultural context. Beliefs about whether weight was perceived as a problem, the expectation of weight loss and treatment-related beliefs influenced participants' perspectives towards weight loss. Understanding and assessing the contribution of each factor may guide weight management from clinicians treating patients with obesity and osteoarthritis.

Reporting Method: The data are reported using the COREQ guidelines.

Patient Or Public Contribution: Patients contributed to the data collected.

Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by hyperglycemia, insulin resistance, and decreased insulin secretion. With its rising global prevalence, effective management strategies are critical to reducing morbidity and mortality. This systematic review compares the efficacy, safety, and long-term outcomes of four major pharmacological treatments for T2DM: sodium-glucose cotransporter-2 (SGLT2) inhibitors, dipeptidyl peptidase-4 (DPP-4) inhibitors, metformin, and insulin.

Beyond The Basics: Unveiling Superior Vena Cava Compression in Hodgkin's Lymphoma.

Internal Medicine/Pulmonary Critical Care, Appalachian Regional Healthcare, Harlan, USA.

Hodgkin's lymphoma (HL) is a malignancy of the lymphocytes in the lymph nodes and presents with non-specific systemic symptoms like fever, night sweats, and weight loss. While HL often involves the mediastinum, it rarely causes superior vena cava (SVC) syndrome, and eosinophilia is noted in approximately 15% of cases. Here, we report a unique presentation of HL in a 52-year-old male with a history of chronic pruritus, chronic kidney disease, and inactive hepatitis B.

Background Obesity has detrimental personal, societal, and economic consequences and raises the risk of developing chronic diseases such as diabetes and cardiovascular diseases. Diet and exercise behaviors are frequently the focus of weight loss programs. Effective nutrition education is associated with a reduced risk of chronic diseases and body weight management.

Risk assessments are important tools to identify deficits in biosecurity management practices. A major strength of some existing tools is that they facilitate cross-country comparisons. However, a weakness is their failure to account for unique intra-national farming enterprise structures such as, for example, pasture-based dairying.
