Key result
Multitheory model constructs explain ~42% of variance in sustaining low-salt diets in hypertensive adults.
Why the study?
Reducing sodium/salt intake is a public health recommendation for hypertension management, but predictors of low-salt intake behavior among Nigerian hypertensives were not established.
Cross-Sectional (n=149)
The multitheory model of health behavior change is a useful framework for predicting low-salt diet adherence in Nigerian adults with hypertension, which can inform future health education interventions.
May inform salt-reduction education in Nigerian hypertension; extends multitheory model but leaves open intervention efficacy.
One of the public health recommendations for the management of hypertension is the reduction of sodium/salt intake. The purpose of this study was to use the novel multitheory model of health behavior change to predict the initiation and maintenance of low-salt intake among adult Nigerian hypertensives. A quantitative cross-sectional design utilizing a convenience sample of 149 consenting Nigerian adults living with hypertension were self-administered a valid and reliable 39-item instrument. Multivariate regression analysis revealed 40.6% of the variance in initiating the consumption of low-salt diets explained by advantages outweighing disadvantages, behavioral confidence, and changes in physical environment. About 41.8% of the variance to sustain the intake of low-salt diet was explained by emotional transformation, practice for change, and changes in social environment. The results justified the predictive role of multitheory model and adequacy of its utility to build evidence-based health education interventions for hypertension in Nigeria.

Dokun-Mowete et al. (2019) conducted a cross-sectional in Hypertension (n=149). Multitheory model of health behavior change constructs was evaluated on Variance in initiating and sustaining the consumption of low-salt diets. Multitheory model constructs explained 40.6% of the variance in initiating and 41.8% of the variance in sustaining low-salt diet consumption among Nigerian adults with hypertension.
