Summary

The main purpose of this observational study is to determine the effect of nutrition education on the knowledge and behaviour of households towards the consumption of green leafy vegetables, legumes and vitamin C-rich fruits and its influence on haemoglobin levels of (households) mothers, fathers and children. The questions it aimed to answer are:

* What is the effect of nutrition education on knowledge, attitude and practice towards the consumption of green leafy vegetables and legumes among households in Ayawso Central Municipality?
* What are the consumption patterns of green leafy vegetables, legumes and vitamin C -rich fruits among households in Ayawso Central Municipality?
* What is the iron, β-carotene, vitamin C and antinutritional contents of the commonly consumed green leafy vegetables and legumes in Ayawso Central Municipality?
* Is iron bioaccessible in the commonly consumed green leafy vegetables and legumes in Ayawso Central Municipality?
* What is the haemoglobin level of participants at baseline and end line in Ayawso Central Municipality?

The study will address knowledge, attitude and the low intake of these nutrient-rich foods and the high prevalence of iron deficiency anaemia/ anaemia among women, children and men through nutrition education and also examine the iron content and iron bioaccessibility in the indigenous green leafy vegetables and legumes that participants consume.

Participants are aware of indigenous green leafy vegetables, legumes and vitamin C-rich fruits in their environment; however, they do not consume them frequently. They will answer questions on knowledge, attitude and practices towards these foods during the six months study and have their haemoglobin levels determine.

Conditions

Interventions

BEHAVIORAL

Nutrition education on green leafy vegetables and legumes

The nutrition education intervention will be based on the Theory of Reasoned Action, Social Cognitive Theory, and the Health Belief Model to influence key behaviour change factors such as knowledge, attitudes, practices, and beliefs. Educational materials will include stickers featuring indigenous green leafy vegetables, legumes, and vitamin C-rich fruits, with information on their benefits, storage, preparation, and the importance of combining them for enhanced iron absorption. Other materials include videos, messages, and affirmative words on iron deficiency and its prevention. The intervention will be delivered to selected households in the intervention community through biweekly meetings and phone calls over six months. The control community will not receive any intervention from the researcher.
