Objectives To assess the caloric contribution of ultra-processed foods (UPFs), factors associated with UPFs energy intake and investigate the relationship between UPFs energy intake, diet quality and nutrient intake among adolescents in urban slums, Kenya. Methods A cross-sectional household study amongst adolescents (10-19 years, N = 621) collected socio-demographic and dietary intake data. Global Diet Quality Score (GDQS); mean and percentage total energy intake (%TEI) from UPFs; and nutrient intakes were computed. Regression analysis assessed the factors associated with UPFs energy intake, and the association between %TEI from UPFs and diet quality.Results Mean daily energy intake was 1,604 kcal (+/- 550), 25.2% from UPFs. Higher leisure screen time (>= 2 h/day) [OR = 1.9 (1.2-3.1)] was associated with UPFs energy intake. Household wealth index (quintile five vs. one) [OR = 2.6 (1.3-6.0)] was associated with non-UPFs energy intake. UPFs (%TEI) was inversely associated with GDQS score (quartile four vs. one) [beta = -2.9 (-3.4 to -2.1)]. Adolescents with higher %TEI from UPFs (quartile four) had highest total energy, total fat and saturated fat; and lowest protein, fibre, iron, calcium and zinc intake.Conclusion UPFs contribute substantially to adolescents' energy intake and are linked to poor diet quality and nutrient intake.
