Obesity Prevention and Control: Increasing Water Access Combined with Physical Activity Interventions in Schools

Summary of CPSTF Finding

The Community Preventive Services Task Force (CPSTF) finds insufficient evidence to determine the effectiveness of school-based interventions to increase water access combined with physical activity interventions. Evidence is considered insufficient because there were too few studies.

The CPSTF recommends the following related interventions in school settings:

Healthy Eating Interventions Combined with Physical Activity Interventions

Healthy Eating Interventions Alone

Physical Activity Interventions

The CPSTF finds insufficient evidence for two other intervention approaches that focus on healthy eating in schools alone and two other intervention approaches that focus on healthy eating combined with physical activity in schools. Read a summary of the findings from reviews of school-based interventions to prevent obesity.

Intervention

These interventions aim to improve student health by combining interventions to increase water access with physical activity interventions.
  • Water access interventions ensure students have access to safe, free drinking water during the school day. Interventions must include one or more of the following components:
    • Procedures to ensure water fountains are clean and maintained
    • Availability of water fountains and hydration stations throughout the school
    • Policies that allow students to have water bottles in class
  • Physical activity interventions engage students in physical activity each day. Interventions must include one or more of the following components:
    • Physical education classes that engage students in physical activity
    • School policies or practices that provide opportunities for physical activity during the school day (i.e., physical activities for students such as recess and classroom breaks)
    • Large-scale environmental changes that provide or improve space, facilities, or equipment to make physical activity easy and appealing (e.g., renovating a school playground)

Interventions may also include one or more of the following:

  • Healthy food and beverage marketing strategies to promote water consumption and decrease sugar-sweetened beverage consumption
  • Educational programs that address nutrition or build knowledge and skills needed to maintain physically active lifestyles
  • Addition of small-scale equipment to promote physical activity (e.g., jump ropes, balls, cones, team vests, pedometers)
  • Staff involvement
  • Family and community engagement

*Healthier foods and beverages include fruits, vegetables, whole grains, low-fat or fat-free dairy, lean meats, beans, eggs, nuts, and items that are low in saturated fats, salt, and added sugars, and have no trans fats. Less-healthy foods and beverages include those with more added sugars, fats, and sodium.

About The Systematic Review

The CPSTF finding is based on evidence from a systematic review of one study (search period 1990 July 2017).

The systematic review was conducted on behalf of the CPSTF by a team of specialists in systematic review methods, and in research, practice, and policy related to obesity prevention and control.

Context

While there are many approaches available to schools, this CPSTF finding focuses on interventions to increase water access with physical activity interventions. Read a summary of all CPSTF findings for school-based interventions to prevent or control obesity.

Summary of Results

Detailed results from the systematic review are available in the CPSTF Finding and Rationale Statement.

The systematic review included one study.

The single study in this review reported a decrease in consumption of sugar-sweetened beverages, and an increase in the prevalence of overweight or obese.

Summary of Economic Evidence

An economic review of this intervention was not conducted because the CPSTF did not have enough information to determine if the intervention works.

Applicability

Applicability of this intervention across different settings and populations was not assessed because the CPSTF did not have enough information to determine if the intervention works.

Evidence Gaps

The CPSTF identified several areas that have limited information. Additional research and evaluation could help answer the following questions and fill remaining gaps in the evidence base. (What are evidence gaps?)
  • Are these interventions effective?
  • Do school-based interventions that increase water consumption also decrease sugar-sweetened beverage consumption?

Study Characteristics

  • The included study was conducted in The Netherlands with students in grades 2 through 7.

Analytic Framework

Effectiveness Review

When starting an effectiveness review, the systematic review team develops an analytic framework. The analytic framework illustrates how the intervention approach is thought to affect public health. It guides the search for evidence and may be used to summarize the evidence collected. The analytic framework often includes intermediate outcomes, potential effect modifiers, potential harms, and potential additional benefits.

Search Strategies

Effectiveness Review

The following six bibliographic databases were searched between 1990 and July 2017, using the search terms listed below.

  • PubMed
  • Embase (Ovid)
  • CINAHL
  • PsycINFO (Ovid)
  • Cochrane
  • Medline (OVID)

The databases covered publications in medical and social sciences, behavioral sciences, and nursing and allied health. The types of documents retrieved by the search included journal articles, books, book chapters, reports, and conference papers.

Following are search strategies specific for Medline. Search terms and search strategies were adjusted to each database, based on controlled and uncontrolled vocabularies and search software.

Considerations for Implementation

Despite the finding of insufficient evidence, the following are considerations for implementation drawn from studies included in the evidence review, the broader literature, and expert opinion.

The Centers for Disease Control and Prevention offers guidance documents to assist with program implementation.
