The proportion of calories consumed from food-away-from-home has steadily increased among U.S. youth since 1977 [1]. About one-third of their calories are derived from foods away from home, nearly half of which is from full-service and fast food restaurants. These restaurants typically serve foods with more calories per serving than foods served at home [2]. According to nationally representative data collected in 2003–2008, the energy consumption of away-from-home food ranged from 24%–42% of all daily calories for fast food restaurants and 6%–15% of all daily calories for full-service restaurants on a given day among children (2–11 years) and adolescents (12–19 years), depending on the age group and their recall day [3].

Chicken nuggets, macaroni and cheese, French fries, and sugary drinks are common kids' meal options at restaurants [4], even though adult menu items often include healthier choices such as roasted chicken with vegetable sides, pasta Bolognese with a side salad, or fish tacos with guacamole. Given how often children dine in restaurants and the typical food choices on the children's menu, restaurants have an important role to play in influencing the diets of children. In attempts to provide healthier options in restaurants, the National Restaurant Association launched the Kids Live Well program that aims to improve the dietary quality of kids' meals by increasing nutrient-dense foods such as fruits and vegetables while reducing calories [56]. A recent review of the Kids Live Well program showed mixed results; healthy kids' meals sales increased in full service restaurants compared to baseline and decreased in quick service restaurants [7]. These changes are a great start but not all restaurants have the resources to implement healthy kids' meal strategies. Another restaurant strategy to address childhood obesity is to encourage restaurants to offer smaller portions of adults' meals for children. A recent study found that children who ate the same meals as their parents had healthier diets than those who ate meals typically considered “children's food” [8]. However, no study has looked at the parents' desire for smaller-portioned meals for their children at restaurants in the United States. Therefore, this study examined parents' preference for restaurants to offer smaller, lower-priced child portions of all menu items and reasons for the preference.

Among the 1,299 parents included in the analytic sample, over half were 35–49 years old (53%), female (56%), and non-Hispanic white (63%). About 39% were college graduates, most were married or in domestic partnership (82%), and 37% had an annual household income of $35,000–$74,999. About 70% of all parents reported that they would like restaurants to offer smaller, lower-priced child portions of all menu items (Table 1). Based on the bivariate analyses, overall, the preference was not significantly different by parental sociodemographic characteristics or weight status. However, based on multivariable logistic regression analysis, the adjusted odds of preference for restaurants to offer child portions of all menu were significantly higher among Hispanic parents (OR, 1.95; 95% CI, 1.20–3.16 vs. non-Hispanic white), but significantly lower among parents with lower education level (OR, 0.64; 95% CI, 0.42–0.97 for ≤ high school and OR, 0.69; 95% CI, 0.48–0.99 for some college vs. college graduate) and parents residing in the Midwest (OR, 0.61; 95% CI, 0.41–0.90) or West (OR, 0.58; 95% CI, 0.38–0.87) compared to those in the South (Table 1).

Among parents who would like restaurants to offer smaller, lower-priced children's portions of all menu items (n = 897), the top three reasons reported were: 1) wanting my child to eat healthier foods that are not offered on the children's menu (72.3%), 2) wanting my child to develop a taste for diverse foods (53.1%), and 3) ordering from the adult menu provides more options for my child (41.9%) (Figure 2).

In the present study, nearly 7 out of 10 U.S. parents with a child younger than 18 years, reported that they would like restaurants to offer smaller, lower-priced child portions of all menu items. It is unclear why Hispanic parents were twice as likely as white parents to say that they would like restaurants to offer small portions for children. One possibility may be related to the type of cuisine that Hispanic families consume when they eat out. If Hispanic families are more likely to eat at Mexican or other Hispanic restaurants, they may be accustomed to ordering adult-sized meals for their children even though they would prefer to have child portions, as these restaurants do not typically offer a children's menu [10].

In the present study, parents with lower education compared to college graduates were less likely to want child portions of all menu items. Parents who attained a lower education may not know the importance of diet quality [11], or appropriate portions for their children may not be their main concern when eating out. Our findings showed that parents residing in the Midwest and West compared to the South were less likely to want child portions of all menu items. Potential reasons for these regional differences are unclear. The South has a higher obesity rate [12] and some poorer dietary patterns, such as higher consumption of sugar-sweetened beverages [13], than other regions in the U.S., which could be a driving factor for wanting more opportunities for their children to eat healthy when eating out.

In the current study, parents reported wanting child portions for all menu items primarily because they wanted their child to eat healthier foods that are not offered on the children's menu. Previously, among parents who did not purchase kids' meals, about 37% of parents responded that they were willing to purchase kids' meals if more healthy options were available in restaurants [14]. In a previous intervention study in 13 outlets of a full-service restaurant chain that serves more than 4 million customers annually, offering healthier children's menus resulted in growth in total revenue exceeding the average revenue growth in leading family dining chains for the same period [11]. Although the current study did not specifically ask about the healthfulness of restaurant meals, restaurants could consider adding child portions for all meals in the effort to provide a wider range healthier menu items for children [1516].

To our knowledge, this is the first study to examine parents' preferences for children's portions of all restaurant menu offerings. However, this study has a few limitations. First, the SummerStyles survey used a sample of adults from an online consumer panel survey. Thus, current findings may not be generalizable to all U.S. parents. However, data were weighted to match the U.S. Current Population Survey proportions for sex, age, household income, race/ethnicity, household size, education level, census region, metro status, and internet access prior to joining the panel. Second, when asked about children's portions for all menu items, the study question did not exclude less healthy items for children, such as sugar-sweetened beverages or high-calorie foods from the menu. It is possible that some parents did not respond that they would like restaurants to offer children's portion of all menu items because they believe that children's menu items should be healthy. Lastly, assessment of acculturation might have provided understanding for why Hispanic parents were twice as likely to report wanting smaller, child-sized portions from full adult menus compared to non-Hispanic Whites. Future research is warranted to understand how acculturation might influence Hispanic parents' ordering habits for their children at the restaurants.

In conclusion, 7 out of 10 parents wanted smaller, lower-priced children's portions of menu offerings at restaurants, mainly because they wanted their children to have healthier foods that are not offered on the children's menu and to develop a taste for diverse foods. Restaurants can use this information in efforts to increase options for children.
