Predictors of Diabetes Health Literacy and Numeracy Among Urbanized Older Adults in Malaysia

ABSTRACT

@#Introduction: Diabetes health literacy and numeracy are health indicators of increasing attention to empower diabetic self-management. This study aimed to explore the predictors of diabetes health literacy and numeracy among urbanized older adults. Methods: A total of 408 older adults with type 2 diabetes mellitus, aged 50 years and older were recruited using stratified random sampling from eight health clinics in Petaling district. A pre-tested questionnaire was used to measure knowledge, attitude, self-efficacy, self-care behavioral skills, diabetes health literacy and numeracy related to diabetes mellitus, as well as the sociodemographic background. Multivariable linear regression was used to understand and rank the predictors of diabetes health literacy and numeracy among the respondents. Results: The total mean score for diabetes health literacy was 53.74 ± 0.60, which was significantly predicted by age (β = -0.21, p=0.01), secondary (β =12.21, p<0.001) and tertiary (β = 16.37, p<0.001) education levels, non-Malays (β = -5.83, p<0.001), being employed (β = -2.77,p=0.02), have other comorbidities (β = -3.02, p=0.003), diabetes related self-efficacy (β = -0.37, p=0.02) and self-care behavioral skills (β =0.36, p<0.001). Meanwhile, the total mean score for diabetes health numeracy was 1.50 ± 0.13 and was significantly predicted by age (β=-0.15, p<0.001), secondary (β=1.09, p=0.002) and tertiary (β=2.24, p<0.001) education levels, and attitude towards diabetes (β=0.16, p<0.001). Conclusion: Very low diabetic numeracy was observed, which was predicted by increased age, low education and low attitude score towards managing diabetes. Hence promoting diabetic numeracy should be targeted among older adults with identified risks.
