Abstract

Background
This study examined the effects of a nutrition education intervention on dietary habits and nutritional knowledge among adults in Liberia. Six research questions guided the study, which adopted a descriptive survey approach involving adults drawn from five counties in Liberia. Data was collected using a structured questionnaire, and 744 respondents were included in the analysis. The data were analyzed using frequencies, percentages and appropriate inferential statistical techniques. The findings showed that the largest proportion of respondents were aged 20–29 years (46.0%), 56.7% were males, 55.1% were single, 55.4% had tertiary education, and 48.1% were students. Nutritional knowledge improved significantly following the intervention, with the proportion of respondents having good knowledge increasing from 90.9% at pre-intervention to 94.1% at post-intervention and the mean knowledge score increasing from 13.96 ± 2.3 to 14.37 ± 1.5, although the magnitude of the improvement was small. In contrast, overall dietary practices did not improve after the intervention, as the proportion with good dietary practices decreased from 12.6% to 7.8% and the mean dietary-practice score declined from 31.12 ± 3.5 to 30.07 ± 3.4. There was also no statistically significant relationship between nutritional knowledge and dietary practices among the respondents. Education level and occupation were significant predictors of nutritional knowledge, while occupation was the major sociodemographic factor associated with dietary practices. Community support, availability of healthy foods, lower food prices and improved cooking skills were significant facilitators of healthier dietary practices, whereas the cost of healthy foods, limited availability, lack of time, family food preferences, lack of motivation, distance to markets, taste preferences and lack of money constituted significant barriers at 0.05 significant levels. The study concluded that the nutrition education intervention produced a modest improvement in nutritional knowledge but did not result in a corresponding improvement in overall dietary practices; therefore, nutrition education programmes should be complemented by measures addressing food affordability, accessibility, practical food-preparation skills and other economic and social barriers to healthy eating.
Objective:
1. Compare pre- and post-intervention nutritional knowledge among adults in Liberia.
2. Compare pre- and post-intervention dietary practices/habits among adults in Liberia
3. Relationship between nutritional knowledge and dietary behavior changes before and after the intervention among adults in Liberia.
Methods:
This chapter discussed the research design, study area, study population, sample and sampling process, research instrument, instrument validity, instrument reliability, data collecting method, ethical approval, and method of data analysis.
Conclusion
This study investigated the effect of a nutrition education intervention on dietary habits and nutritional knowledge among adults in Liberia. The results demonstrated a significant improvement in both areas following the intervention. Participants showed a marked increase in their understanding of essential nutritional concepts, such as portion control, balanced diets, and the importance of fruits and vegetables.
