Measuring and Influencing Behavior Change in Dietary Intake: Integrated Photovoice Approach in Nutrition...

A study conducted in two wards of Tharaka Nithi subcounty in Kenya documented the impact of using photovoice as a learning tool to build awareness about diets in order to influence behavior change, as well as a method to measure dietary intake. After a year's nutrition awareness drive using Smart Food branding, in the intervention area, a total of 60 participants from intervention and control areas were identified for the photovoice exercise. The analysis showed household and women's dietary diversity scores to be higher in the intervention group by 35% and 45%, respectively. An estimate of nutrient intake revealed a higher intake of calories, protein, calcium, iron and zinc ranging from 70% to 205% in the intervention group. Qualitative feedback on the photovoice approach reflected increased nutrition awareness and behavior change. Results showed the efficacy of the approach in evaluating diets while simultaneously improving participants' realization of what they were consuming using images captured and a one-on-one discussion with nutritionists. The improvement in dietary diversity scores reflected the effectiveness of this creative participatory and branded approach in imparting a strong message on and enthusiasm for learning about nutrition, resulting in behavior change.
