Undergraduates may lower their risk of developing chronic non-communicable diseases (NCDs) such as; diabetes, cardiovascular diseases, and cancer which are consistently among the top eight leading causes of death globally by improving their nutrition knowledge and attitude towards nutrition. The study evaluated the effect of nutrition education and mobile phone communication intervention on undergraduates’ knowledge and attitude of a healthy diet in Oyo-state, Nigeria.

This study employed a quasi-experimental research design among 100 undergraduate students selected through a multistage sampling technique from four universities. There were four groups: control, nutrition education alone, mobile phone communication alone, and nutrition education and mobile phone communication intervention. An 8-week follow-up was done after the study implementation. Data were analysed using descriptive and inferential statistics to test the effectiveness of the interventions. All statistical tests were at 5% level of significance.

All the respondents were single (100%). Mean age of respondents was 19.80 ± 2.22, knowledge about healthy diet and attitude towards healthy diet among respondents in all four groups at baseline was poor. A combination of the nutrition education and mobile phone communication intervention exhibited significant increase in the respondents’ knowledge of healthy diet by 19.93% from baseline (13.91 ± 3.48) to endline (19.69 ± 2.73), with a big level of effect (ES = 0.602), this is the highest effect size of all the groups. Mobile phone communication alone had the highest increase in attitude mean score by 20.33%.

A combination of educational program with reminder strategies improves knowledge retention and attitude of respondents.
