Introduction: To determine the prevalence of reaching multiple Healthy People 2020 (HP 2020) objectives including nutrition and weight status, sleep health, physical activity, health-related quality of life, social determinants of health, and education among low-income, diverse children and adults. Methods: Children ages 5- to 7-years-old (n = 150; 47% female) and their parents (mean age = 35; 91% mothers) from 6 racial/ethnic and immigrant/refugee groups (n = 25 from each; African American, Native American, Hispanic, Hmong, Somali, White) participated in this cross-sectional mixed-methods study. Results: Overall, the majority of HP 2020 objectives were not being met across this low-income, racially/ethnically diverse, and immigrant/refugee sample of children and adults. In particular, African American children and parents consistently fell below the majority of the HP 2020 targets, with only 5 of the 24 HP 2020 objectives being met. Additionally, immigrant children and parents met less than 2/3 of the HP 2020 objectives. Discussion: Concerted public health efforts are needed to address the disparities in reaching the HP 2020 objectives and informing the development of the future HP 2030 objectives among low-income, racially/ethnically diverse, and immigrant children and parents. In order to achieve and assess the current and future HP objectives in these diverse populations, changes may be needed in both interventions and assessment tools.
