Behavioral Intention towards Dietary Diversity among Adult People Living with HIV in Public Hospitals in Southwest Ethiopia Using Theory of Planned Behavior—An Explanatory Study

Abstract

Dietary diversity is a crucial element of inclusive care for people living with HIV (PLWHIV). Particularly in resource-limited countries where undernutrition and food insecurity prevail, low intention and poor attitude towards diversified diets are the common challenges. The aim of this study was to assess the intention towards dietary diversity behavior among adult PLWHIV in Jimma Zone public hospitals, Southwest Ethiopia. A hospital-based survey study was carried out in five public institutions among 403 sampled adult PLWHIV. Data were entered into Epi-Data (The EpiData Association, Odense, Denmark) and exported to SPSS version 20 (IBM, Armonk, NY, USA) for analysis. Relationships among variables were assessed using correlation coefficients. A multivariable linear regression model was fitted to assess predictors of behavioral intention towards dietary diversity at p-value ≤ 0.05. The quantitative data were supplemented by qualitative data, which were collected through key informant interviews and analyzed thematically. The significant predictors of intention to use dietary diversity were attitude (β = 0.196, p p < 0.01) of the adult PLWHIV. The constructs of theory of planned behavior (TPB) independently explained the variance in intention towards dietary diversity by 25.7%. All the intermediate, proximal and distal components of the theory of planned behavior (TPB) explained the final model finding 32.2% of variance in the intention to use dietary diversity. The qualitative findings indicated that delivery of HIV care requires a sense of livelihood development, economical improvement and creating a sense of ownership for sustainable HIV care by creating behavioral change at the individual level. Conclusion: Dietary inadequacy was strongly correlated with being in the sociodemographic groups that are at heightened risk of adverse clinical outcomes. It is worthwhile to understand behavioral intention as a potential determinant of malnutrition and the Poor ART outcomes rather than symptomatic treatment of malnutrition with food by prescription.
