Body image in COPD and its relation with physical activity levels, lung function and body composition: An observational study

Association of body size distortion with low body mass index in female patients with nontuberculous mycobacterial lung disease

BACKGROUND

We have previously reported that female patients with nontuberculous mycobacterial lung disease (NTM-LD) are thinner and eat less than healthy controls. Therefore, we hypothesized that their thinness is associated with body size misperception. The aim of this study was to clarify whether patients' body size perception (BSP) is associated with body mass index (BMI) independent of potential confounders.

METHODS

In this cross-sectional study, we assessed 81 outpatients for BSP using the Japanese version of Body Image Scale, body composition, dietary intake, and biochemical markers. As a control, we used BSP and self-reported anthropometric data from 111 healthy women collected via a web survey. First, BSP and BMI were compared between the patients and the controls. Second, patient data was compared between patients who overestimated their body size (OE, n = 31) and a control who did not (Non-OE, n = 50). Multiple regression analysis was performed to clarify the association between BSP (independent variable) and BMI (dependent variable), adjusting for potential confounders, such as age, disease duration, and nutritional factors.

RESULTS

There was a negative correlation between body size distortion and BMI in both patients and controls (p < 0.001, both). In interpatient comparisons, the OE group had significantly lower BMI and body fat percentage (p < 0.001, both), normalized energy (p = 0.037), and protein (p = 0.013) intakes, and significantly greater weight loss from age 20 (p = 0.003) than the Non-OE group. Multiple regression analysis revealed that overestimation of body size was associated with lower BMI independent of confounders, such as longer disease history, longitudinal weight loss, and nutritional factors.

CONCLUSION

These findings suggest that body size distortion is an etiological factor for lower BMI in female patients with NTM-LD. Thus, it may be important to understand the patient's body image when providing dietary advice.

Chronic Obstructive Pulmonary Disease and Social Determinants of Health: A Case of Marginalization in Rural Appalachia

Chronic obstructive pulmonary disease remains a challenging epidemic across the United States. This serious illness impacts nearly twice as many individuals in the rural area compared with urban counterparts. As the disease progresses, the symptom burden and needs of the patient and caregivers escalate. Access gaps to services, such as hospice and palliative care, and the social determinants of health found in Appalachia may lead to marginalization and social injustice. Defined as the condition of being peripheralized based upon one's social margins of identity, associations, and/or environment, marginalization impacts health outcomes and quality of life. This article explores the triple threat of marginalization for patients with chronic obstructive pulmonary disease living in rural Appalachia. By recognizing marginalization and designing initiatives to reduce the impact, hospice and palliative care nurses serve as advocates and leaders to influence systemic change through partnerships with key policymakers and legislators.
