With the rapid population growth of older people, understanding the intricate relationship between depression, obesity and malnutrition, alongside the role of physical activity in this dynamic, is crucial for effective NCD management. These correlations are vital for implementing targeted strategies to manage NCDs and improve the quality of life for older people in a region where such strategies are critically needed but often underrepresented.
This cross-sectional study sampled older adults (≥ 60 years) from randomly selected LTCF in eThekwini, KwaZulu-Natal, South Africa, all of whom could provide informed consent. Outcome measures of depression, BMI, waist-hip-ratio, and physical activity were recorded.
A total of 396 participants (mean age 73.39 years) from 17 LTCFs, including 22% from rural areas, met the inclusion criteria. Obesity and depression were prevalent in 63.64% and 35.10% of the cohort, respectively. In a statistically significant ordinal regression model BMI was a significant predictor (B = 0.10, p = 0.007) for depression. Conversely in a liner regression model, BMI had a significant inverse relationship with depression (B = -2.01, p = 0.004) and physical activity.
Depression was identified to exert a profound impact on the nutritional status of older people, often exacerbating both obesity and malnutrition. Implementing physical activity interventions that address both mental health and physiological risk factors can be instrumental in effectively managing comorbidities within this population thereby improving quality of life.
As physiotherapists, we leverage physical activity as a powerful tool, designing targeted programmes to enhance daily functioning, reduce fall risks and lower stroke incidence, while optimizing rehabilitation in older people. Beyond the delivery of direct patient care, physiotherapists play a crucial role in advancing health literacy among patients, healthcare professionals, and key stakeholders. They elucidate the fundamental influence of physical activity in mitigating and managing depression, while concurrently addressing its broader implications for the reduction of NCDs prevalence. We are not just healthcare providers; we are champions of healthy aging. By advocating for and implementing strategic physical activity interventions, we not only improve individual health outcomes but also contribute to reducing future healthcare costs, reinforcing our essential role in this region.
