Food insecurity and associated health and social determinants among older adults in Ghana: Analysis of the WHO's study on global AGEing and adult health (SAGE), 2014-2015.

This study was conducted to assess the prevalence and factors associated with Food Insecurity (FI) and further quantify its association with unmet need for health services and health-related outcomes among older adults aged 50 years and above in Ghana. The Ghana Study on Global AGEing and Adult Health was used. Body Mass Index (BMI), depressive episodes, functional difficulties (FD), low Quality of Life (QoL), memory decline, and Unmet Needs of Health Services (UNHS) are the the study outcomes. Ordinary Least Square, and Poisson regression analysis modified with Mahalanobis distance matching within propensity score caliper weights were employed. Stata 16.1 was used to perform analysis and a p-value < 0.05 was deemed significant. The prevalence of FI among older adults aged 50 years or older in Ghana was approximately 28 %(95 %CI = 24.5-31.7) and was strongly associated with lower educational attainment and social support. The prevalence ratio of depression, FD, low QoL and UNHS among older adults who experienced FI were; 3.43(95 %CI = 2.25-5.21), 1.18(95 %CI = 1.12-1.23), 2.01(95 %CI = 1.54-2.62), and 1.46(95 %CI = 1.01-2.11). Memory significantly decreased by 85 percentage points% among food insecure older adults [aβ(95 %CI) = -0.85(-1.62--0.07)]. Older adults with relatively higher educational attainment and social support are less likely to suffer FI and associated limited health and poor social well-being. In the national quest to achieve SDG 2, these health and social determinants of FI among older adults should be considered in the implementation of the national ageing policy to improve the health and well-being of older adults in Ghana.
