Abstract
Background:
State policies have the potential to improve early care and education (ECE) settings, but little is known about the extent to which states are updating their licensing and administrative regulations, especially in response to national calls to action. In 2013, we assessed state regulations promoting infant physical activity in ECE and compared them with national recommendations. To assess change over time, we conducted this review again in 2018.
Methods:
We reviewed regulations for all US states for child care centers (centers) and family child care homes (homes) and compared them with three national recommendations: (1) provide daily tummy time; (2) use cribs, car seats, and high chairs for their primary purpose; and (3) limit the use of restrictive equipment (e.g., strollers). We performed exact McNemar's tests to compare the number of states meeting recommendations from 2013 to 2018 to evaluate whether states had made changes over this period.
Results:
From 2013 to 2018, we observed significant improvement in one recommendation for homes—to use cribs, car seats, and high chairs for their primary purpose (odds ratio 11.0; 95% CI 1.6–47.3; p = 0.006). We did not observe any other significant difference between 2013 and 2018 regulations.
Conclusions:
Despite increased awareness of the importance of early-life physical activity, we observed only modest improvement in the number of states meeting infant physical activity recommendations over the past 5 years. In practice, ECE programs may be promoting infant physical activity, but may not be required to do so through state regulations.
Introduction
Recent calls to action highlight the importance of promoting physical activity and decreasing sedentary time for very young children.1–5 A small but growing body of evidence suggests that physical activity during the first year of life has important biological and behavioral health implications.6–8 Moreover, a recent systematic review found evidence of tracking of physical activity within early childhood (birth to 5 years) and from early to middle childhood. 6 Thus, promoting physical activity and decreasing sedentary time in infancy appear critically important for later health. However, few studies have measured physical activity and inactivity in infants.8–10 Based on available evidence, infants may not be achieving recommended levels of physical activity. A study from Australia found that the majority of infants assessed did not meet current 24-hour movement guidelines. 11 In particular, few infants were provided with sufficient tummy time by parents and other caregivers and approximately half of infants spent excessive time in confining equipment, such as strollers, car seats, and swings. 11 Furthermore, in a study of young children from Canada that included a small sample of infants, few met physical activity guidelines and the majority were sedentary for a large percentage of waking hours. 12
Parents and other caregivers can promote physical activity and limit inactivity in infants by providing daily tummy time for younger infants, allowing infants to move freely on the ground, and limiting time spent in restrictive equipment. It is important to provide opportunities for physical activity for infants at home and in other settings where infants spend time. Out-of-home child care for young children has become more prevalent in recent years, and parents now share the caregiving responsibility with other adults. In developed countries, approximately one-quarter of children younger than 3 years spent time in early care and education (ECE) settings. 13 Among infants in the United States, nearly 16% spent time in more formal child care facilities and ∼35% were cared for in less formal arrangements. 14 Thus, ECE settings have become important targets for obesity prevention through the promotion of physical activity and the reduction of sedentary time.1–3,5
In 2013, we conducted a review of state licensing and administrative regulations for ECE related to infant physical activity and compared them with national recommendations. 15 We found that the majority of states lacked regulations consistent with the recommendations and that this was especially true for family child care homes. Since our prior review, more than two-thirds of states have updated their regulations. Thus, we were interested in assessing whether states had made changes to their regulations related to infant physical activity. We hypothesized that more states would have regulations consistent with national recommendations due to growing attention to the issue of early-life obesity prevention and the promotion of physical activity during infancy. Therefore, the purpose of this study was to assess current infant physical activity regulations for ECE facilities, compare them with national recommendations, and evaluate the extent to which states have enacted new regulations over the past 5 years, since our prior review. We also aimed to display our findings graphically to allow for better visualization of states with and without regulations meeting the national recommendations.
Methods
Infant Physical Activity Recommendations
The infant physical activity recommendations were put forth in Early Childhood Obesity Prevention Policies by the National Academies of Sciences, Engineering, and Medicine (formerly the Institute of Medicine) in 2011 as recommended actions for states interested in enhancing their regulations. 1 These recommendations encouraged ECE providers to (1) provide daily tummy time (in the prone position) for infants younger than 6 months; (2) use cribs, car seats, and high chairs for their primary purpose—cribs for sleeping, car seats for vehicle travel, and high chairs for eating); and (3) limit the use of restrictive equipment such as strollers, swings, and bouncer seats/chairs for holding infants while awake. States were encouraged to consider these recommendations when enacting new regulations but were not required to do so. We conducted a review of state regulations following the release of these recommendations. 15 Our current review serves as an update, documenting regulations that have been enacted within the past 5 years, since our prior review.
Review of Regulations
For this cross-sectional study, we reviewed state regulations for ECE facilities current as of May 31, 2018. We obtained regulations for all 50 US states and the District of Columbia from the National Database of Child Care Licensing Regulations maintained on a publicly available website by the US Department of Health and Human Services. 16 Two independent reviewers coded each state's regulations to assess consistency with the recommendations using a combination of keyword searches and review of the full regulations text. Regulations needed to include specific language embodying the spirit of each recommendation. Percent agreement between the two reviewers was 98% (provide daily tummy time), 67% (use cribs, car seats, and high chairs for their primary purpose), and 83% (limit the use of restrictive equipment). We reconciled differences through a collective research team discussion until both reviewers and the principal investigator were all in agreement.
We reviewed regulations for the main types of child care facilities, child care centers (centers) and family child care homes (homes), consistent with prior ECE regulatory reviews.15,17–23 Typically, states have separate regulations for centers and homes, although in some instances the same set of regulations governs both types of facilities. Generally, centers have a greater number of staff members, care for more children, and are located in a separate, dedicated building. Family child care homes typically include one provider, who is often the owner, with fewer children. As we did for our prior studies,15,17,24,25 we grouped subcategories of facilities into either centers or homes for the purpose of this review. This categorization is especially important, as centers and homes represent two distinct types of ECE settings and the enactment of new regulations often varies substantially between centers and homes. Ethical approval was not required by the Johns Hopkins Bloomberg School of Public Health as human subjects were not included in this regulations review.
Analysis
We calculated the number of regulations consistent with each of the three infant physical activity recommendations by state and ECE facility type. We then performed exact McNemar's tests to compare the number of states meeting recommendations in 2013 with 2018 for both centers and homes. We present results in terms of odds ratios, 95% CI, and two-sided p-values. We conducted all analyses using SAS 9.4 (SAS Institute, Inc., Cary, NC), with a significance level of α = 0.05. Next, to graphically display our results, we used ArcGIS (ArcGIS 10; ESRI, Inc., Redlands, CA) to map the number of regulations consistent with each recommendation for centers and homes between 2013 and 2018. Visual depiction allows for a relatively quick assessment of change over time and facilitates an at-a-glance comparison of states with their neighbors.
Results
Overview
Since our prior review in 2013, 38 states updated their regulations for centers and 34 states updated their regulations for homes. South Carolina and Arizona had the oldest regulations, updated last in 2005 and 2007, respectively. A small number of states had regulations for centers consistent with all three recommendations, including Arizona, Colorado, the District of Columbia, Georgia, New York, Oklahoma, Washington, and West Virginia (Table 1). Colorado, the District of Columbia, Georgia, Illinois, New Jersey, and New York were the only states with regulations for homes consistent with all three of the recommendations. From 2013 to 2018, we observed significant improvements in one recommendation for homes—to use cribs, car seats, and high chairs for their primary purpose (odds ratio 11.0; 95% CI 1.6–47.3; p = 0.006) (Table 2). There were no significant improvements for the other recommendations for centers or homes. Results are displayed in the 2013 and 2018 maps presented in Figure 1.

Provide Daily Tummy Time for Infants Younger Than 6 Months
In 2013, 11 states had regulations requiring centers to provide daily tummy time for infants younger than 6 months; this increased to 16 states in 2018. For homes, the number of states with regulations requiring tummy time increased from 9 to 10 from 2013 to 2018, although one state removed the regulation and another added the regulation. Some states required a minimum number of minutes of tummy time each day or multiple times per day. New Jersey regulations for centers, for example, provided, “[s]taff members shall ensure infants have age-appropriate, supervised tummy time at least twice per day.” Virginia regulations for homes provided, “[i]nfants, who cannot turn themselves over and are awake, shall be placed on their stomachs a total of 30 minutes each day to facilitate upper body strength and to address misshapen head concerns.”
Use Cribs, Car Seats, and High Chairs for Their Primary Purpose
In our prior review, 24 states required centers to use cribs, car seats, and high chairs for their primary purpose only, compared with 31 states in 2018. Homes also improved in the number of states with regulations consistent with this recommendation, increasing from 20 in 2013 to 30 in 2018. For example, New York regulations for centers provide, “[c]hildren may not sleep or nap in car seats, baby swings, strollers, infant seats, or bouncy seats. Should a child fall asleep in one of these devices, he or she must be moved to a crib/cot or other approved sleeping surface.” Mississippi regulations for both centers and homes are nearly identical to the language of the recommendation in that they provide, “[c]ribs, car seats, and high chairs are to be used only for their primary purpose, i.e., cribs for sleeping, car seats for vehicle travel, and high chairs for eating.”
Limit the Use of Restrictive Equipment for Holding Infants While Awake
For centers, 29 states limited the use of restrictive equipment in 2013, compared with 33 in 2018. For homes, the number of states with this regulation increased from 23 to 26. Regulations for Mississippi homes mirror the recommendation and provide, “[p]roviders should limit the use of equipment such as strollers, swings, and bouncer seats/chairs for holding infants while they are awake.” About half of states include a time limit for infants in restrictive equipment. Colorado regulations for homes, for example, provide, “[c]hildren must not be confined for prolonged periods of time to cribs, playpens, swings, high chairs, infant seats, or other equipment that confines movement. They must have an opportunity each day for freedom of movement, such as creeping, crawling, or walking in a safe, clean, open, uncluttered area. Children who are awake must not be confined for more than fifteen (15) minutes at a time to cribs, playpens, swings, high chairs, infant seats, or other equipment that inhibits freedom of movement. Children who are actively eating may be in a high chair or other approved feeding equipment for longer than fifteen (15) minutes. Children must be moved away from the feeding location once feeding is complete.” Similarly, Delaware regulations for homes provide, “[a] licensee shall ensure children are not in cribs, pack-n-plays, swings, high chairs, seats, or stationary activity centers for more than 30 minutes at a time while awake. Toddlers and infants, as appropriate, shall be provided with an activity during this time. After removing the child from the equipment, children shall be able to move freely on the floor.”
Discussion
We observed only modest improvement in state regulations for the three infant physical activity recommendations examined. States significantly increased the number of regulations targeting homes that were consistent with the recommendation to use cribs, car seats, and high chairs for their primary purpose only from 2013 to 2018. In addition, when we considered regulations consistent with all three recommendations collectively, states appeared to make substantial improvement for regulations governing homes over time. However, we did not observe any significant changes in state regulations for centers for any of the physical activity recommendations. Although we observed few changes states made for regulations targeting centers, states may be in the process of updating their regulations at any given time. Therefore, it is useful to conduct assessments periodically to assess change over time.
Previous reviews have found that states varied widely in their regulations related to children's physical activity.15,18,19,26 However, these cross-sectional regulatory reviews are limited in their ability to provide information about actual practice in ECE. Two prior studies have prospectively assessed compliance with new state physical activity policies targeting preschoolers (one a state regulation and the other a mandatory state standard) and found some improvement.27,28 State regulations have the potential to impact physical activity practices, although more evidence is needed demonstrating the effectiveness of new regulations—especially for infants.
We did not see much improvement in the number of states with regulations related to tummy time, despite recent research and practice recommendations to offer tummy time for infants younger than 6 months at least daily. Tummy time provides infants with supervised time spent on their stomachs in the prone position and has demonstrated positive effects on infant physical and behavioral development.29–31 A recent review of correlates of tummy time reviewed 15 studies from seven countries; not surprisingly, tummy time was higher when parents and other caregivers prioritized time for infants to spend on the floor in the prone position. 32 Another recent study assessed ECE provider adherence to tummy time and other infant physical activity recommendations in Australia, Canada, and the United States. The researchers found that ECE providers reported setting aside adequate tummy time for infants, but fewer reported limiting the use of restrictive equipment for infants in care. 33
Some states enacted new regulations requiring ECE providers to use cribs, car seats, and high chairs for their primary purpose. However, based on the wording of these regulations, states may have been motivated by a desire to prevent sleep-related infant deaths. Many state regulations required ECE providers to move infants who have fallen asleep in car seats or other inappropriate sleeping locations to a crib. Sudden infant death syndrome and accidental sleep-related suffocation are common types of sudden unexplained infant deaths (SUID). 34 In our prior review of state regulations, we attempted to separate and categorize sleep regulations related to obesity versus SUID prevention. 17 However, we were not able to do so in this review, as not allowing infants to sleep in car seats, for example, has both SUID and physical activity benefits.
Similarly, the use of confining equipment, including strollers, swings, and bouncer seats for holding infants while awake, is problematic for a number of reasons. These devices restrict movement and also limit infants' ability to engage freely in their environments, which could impact cognitive, language, and physical (motor) development.7,29,35–37 Two recent studies suggest that the use of restrictive equipment is prevalent in ECE settings.33,38 However, we found that just over half of states had regulations limiting the use of strollers, swings, and other types of confining equipment. This could be an important area for improvement, as states consider updates to their regulations.
Conclusions
A number of national organizations have put forth recommendations and standards to promote infant physical activity and reduce inactivity.1–5 ECE programs are a primary target, as these settings can be regulated by states. State licensing and administrative regulations for ECE programs have the potential to promote infant physical activity; emerging evidence in slightly older children suggests that new regulations may be an effective way to increase physical activity.28,39 Thus, states may consider additional regulations to support and enhance infant physical activity in future updates to regulations.
