The availability and consumption of commercially produced foods and beverages have increased across low‐income and middle‐income countries. This cross‐sectional survey assessed consumption of commercially produced foods and beverages among children 6–23 months of age, and mothers' exposure to promotions for these products. Health facility‐based interviews were conducted among 218 randomly sampled mothers utilizing child health services in Dakar, Senegal; 229 in Dar es Salaam, Tanzania; 228 in Kathmandu Valley, Nepal; and 222 in Phnom Penh, Cambodia. In the day prior to the interview, 58.7% of 6–23‐month‐olds in Dakar, 23.1% in Dar es Salaam, 74.1% in Kathmandu Valley, and 55.0% in Phnom Penh had consumed a commercially produced snack food. In the previous week, the majority of children in Dakar (79.8%), Kathmandu Valley (91.2%), and Phnom Penh (80.6%) had consumed such products. Consumption of commercially produced sugar‐sweetened beverages was noted among 32.0% of Phnom Penh, 29.8% of Dakar, 23.1% of Dar es Salaam, and 16.2% of Kathmandu Valley children. Maternal education was negatively associated with commercial snack food consumption in Dakar and Kathmandu Valley. Children of Phnom Penh mothers in the lowest wealth tercile were 1.5 times more likely to consume commercial snack food products, compared to wealthier mothers. These snack consumption patterns during the critical complementary feeding period demand attention; such products are often high in added sugars and salt, making them inappropriate for infants and young children.

This study assessed the promotion of commercially produced foods and consumption of these products by children less than 24 months of age in Dakar Department, Senegal. Interviews with 293 mothers of children attending child health clinics assessed maternal exposure to promotion and maternal recall of foods consumed by the child on the preceding day. Promotion of breastmilk substitutes and commercially produced complementary foods outside health facilities was common with 41.0% and 37.2% of mothers, respectively, reporting product promotions since the birth of their youngest child. Promotion of commercially produced snack food products was more prevalent, observed by 93.5% of mothers. While all mothers reported having breastfed their child, only 20.8% of mothers breastfed their newborn within the first hour after delivery, and 44.7% fed pre‐lacteal feeds in the first 3 days after delivery. Of children 6–23 months of age, 20.2% had consumed a breastmilk substitute; 49.1% ate a commercially produced complementary food, and 58.7% ate a commercially produced snack food product on the previous day. There is a need to stop the promotion of breastmilk substitutes, including infant formula, follow‐up formula, and growing‐up milks. More stringent regulations and enforcement could help to eliminate such promotion to the public through the media and in stores. Promotion of commercial snack foods is concerning, given the high rates of consumption of such foods by children under the age of 2 years. Efforts are needed to determine how best to reduce such promotion and encourage replacement of these products with more nutritious foods.
