The effect of egg supplementation on growth parameters in children participating in a school feeding program in rural Uganda: a pilot study

Background: School feeding programs have gained popularity in developing countries. Eggs are an inexpensive source of micronutrients and high-quality protein. Therefore, the objective of this study was to gain preliminary data regarding the impact of egg supplementation on growth in primary school students participating in a school feeding program in rural Uganda. Methods: Children (ages 6-9; n = 241) were recruited from three different schools located throughout the Kitgum District of Uganda. All participants in the same school received the same dietary intervention: control (no eggs (0 eggs); n = 56), one egg five days per week (1 egg; n = 89), or two eggs five days per week (2 eggs; n = 96). Height, weight, tricep skinfold thickness (TSF), and mid-upper arm circumference (MUAC) were measured monthly over 6 months. Results: Following six months of egg supplementation, participants receiving 2 eggs had a greater increase in height and weight compared to the 0 eggs and 1 egg groups (P < 0.05). In addition, participants receiving 1 egg and 2 eggs had a significantly higher (P < 0.05) increase in MUAC at six months compared to 0 eggs. Conclusion: These results suggest that supplementation with eggs can improve parameters of growth in school-aged children participating in school feeding programs in rural Uganda.
