Preventing Childhood Obesity

No Results Found 0/0

This clinical tool aims to support primary care providers in the prevention of childhood obesity within their practice. It is intended to be used with paediatric patients (2-17 years of age) and their families, irrespective of patient weight. This tool was developed to help guide conversations with patients and their families, as appropriate and over a series of visits, that focus on healthy lifestyle choices and goal-setting. Readiness to change and self-efficacy are key concepts within the conversation.

Discuss healthy lifestyles and agree on a plan

Weight is not always an accurate reflection of lifestyle and nutrition choices. Discussions about healthy and unhealthy choices need to take place with all patients, regardless of how patients track on percentile curves. This section includes tips to help providers initiate discussions about healthy lifestyle choices. Motivational interviewing techniques are suggested to help build rapport and to manage challenging situations. Addressing all aspects of healthy lifestyle and nutrition choices may not be feasible within one visit. The following section acts a guide that can be used over multiple patient visits.

Assess awareness and attitudes towards towards healthy lifestyle habits

Ask patient

  • “Do you mind if we take a few minutes to discuss healthy eating and physical activity?”

If patient is ready to discuss

  • Ask open-ended questions about concerns: 2
    “Do you have any concerns about your/your child’s weight or growth?”
  • Work with patients and families to identify a lifestyle or nutrition behaviour change goal to discuss (see table below for sample topics and goals).
    “Which one of these habits would you like to work on?”

If patient is unsure/unready to discuss

  • Acknowledge lack of readiness:
    “It seems as if you’re not sure/not ready to discuss this right now. If you want to discuss this later, we can do so at your next visit?”
  • Continue to track patient’s growth and follow up at next visit.

Select goal and agree on plan

Select a goal

Assist the patient/patient’s family to choose one or more goals tailored to their needs.

Topic area                                  Discussion points                                                               Sample goals
Importance of satiety/fullness
  • Importance of regular meals and snacks
  • Inclusion of protein with all meals and snacks (e.g., protein fortified cereal)
  • Liquid protein sources aren’t as effective as solids for fullness (e.g., milk vs. yogurt or cheese)
  • Set number of meals with protein/day
  • Set number of snacks with protein/week
Household meals
  • Reliance on processed foods
  • Ultra-processed food and link with obesity
  • Cooking is a life-skill to teach our children
  • Benefits of family meals (benefits extend beyond nutrition) 3
  • Set number of meals cooked with child’s help/week
  • Set number of meals eaten together as a family/week
Reduction of liquid calories

 

  • Aim for solid sources of dairy
  • Juice should not be considered a fruit equivalent
  • Avoid sweet drinks, such as soft drinks, 100% juice, sweetened milk and sports drinks 4
  • Set number of drinks/day
Limit eating out
  • Food Dollars ($) – over half is spent outside of the house
  • Many (96%) fast food kids’ meals exceed recommended daily limits for calories, salt, etc. 5
  • Eating patterns set in childhood carry forward to adulthood
  • Set number of meals out days/week
  • Set number of bagged lunches days/week
Importance of sleep
  • Link to obesity
  • Screen time before bed (e.g., TVs in bedrooms)
  • Set a regular routine
  • Sleep apnea
  • Benefits beyond nutrition (e.g., mood, concentration)
  • Regular sleep time
  • Screens off before bed
Physical activity

 

  • Incorporating activity into daily lives (e.g., take a walk in the neighborhood)
  • Limit screen time
  • Though important to a healthy lifestyle, physical activity cannot offset poor eating habits
  • Set number of walks/week as a family
  • Playtime outdoors

Explore readiness to work on the goal

Determine importance

Ask patient: “How important is this change to you?”

Importance Low (< 7) indicates that patient/patient’s family sees healthy lifestyle as unimportant:

  • Explore the pros and cons of trying to achieve the ‘agreed-on’ goal vs. the pros and cons of keeping actions the same
  • Summarize pros and cons given by patient
  • Ask Importance question again:
    • If < 7, consider choosing a different goal. If one cannot be found, follow up at next visit.
Determine confidence

Ask patient: “How confident are you about making this change?”

Confidence Low (< 7) indicated patient/patient’s family is unconfident in their ability to change:

  • Brainstorm strategies with patient to address potential barriers (e.g., see right) when answering the confidence question
  • Adjust goal to be smaller and simpler
  • Ask confidence question again
    • If < 7, consider choosing a different goal. If one cannot be found, follow up at next visit.

Importance and Confidence High (> 7): Give affirmation of confidence and importance.

Probe to learn more about barriers:
  • Food Environment: e.g., cooking skills, kitchen availability
  • School: e.g., lunch programs, cafeteria options, bullying
  • Socioeconomic status (SES): e.g., single parent, resource constraints for meals (see CEP’s Poverty in Primary Care tool)
  • Caregivers: e.g., lack of active play, insufficient nap time7
  • Cultural: e.g., traditional diet, beliefs, religion
  • Medical Health: e.g., fatigue, chronic conditions, food allergies
  • Mental Health: e.g., depression, emotional eating, eating disorders
Managing Challenging Situations

Select situation to view suggestions

  • Do not confront or oppose. Instead, make a statement that respects their right to decide and opens the door for future discussion
  • Name the emotion, empathize with the patient/family, and explore solutions:
  • Do not state facts that counter shared beliefs. Instead, make a statement that reflects what is being said and gives the patient/family an opportunity to voice concerns

If patient is ready for change but family is not:

  • Review goal list and help patient choose goals that he/she can do with minimal lifestyle changes from the rest of the family (e.g., consider packing healthier lunch options)
  • Work separately with parents to explore their ambivalence toward change.

If family is ready for change but patient is not:

  • Probe to learn more about possible barriers to change (see box above) with patient.
  • Emphasize adding healthy foods and fun activities with family or friends rather than taking away foods or screen time so plan does not seem punitive.

Agree on a Plan

  • Summarize the main points of the discussion and the goal agreed upon.
  • Compliment the patient/patient’s family on their willingness to work on healthy living.
  • Acknowledge choice and offer encouragement.
  • Discuss next steps and follow up at next visit (revisit goals and possibly discuss working on other goals).

Measure, document, and interpret growth

Measure and document growth

Routine growth monitoring allows providers to identify concerns appropriately, while providing an avenue to prompt healthy lifestyle discussions with patients and families.

  • Use quality equipment that is accurate and regularly calibrated to measure patients’ height and weight at both routine and acute/emergent visits.
  • BMI is a strong predictor of future risk of becoming overweight and BMI is associated with negative health outcomes. 9, 10
  • As childhood BMI is consistent with adult BMI: It can be used to track body size from age 2 through adulthood
BMI Calculation
Measuring weight
Measuring height

Interpret Growth Data

  • The 2014 WHO Growth Charts for Canada represent how typical children should grow over a specific period of time. 11
  • For children >2 years of age, the following growth charts are available: 13, 14Weight-for-Age and Length-for-Age
  • Body Mass Index (BMI-for-Age)
  • WHO recommends BMI-for-Age as the best measure after age 10 due to variable age of puberty – tracking weight alone is not advised. 15
  • Percentile curves can be used to understand how the child’s measurements compare to other children of similar age and gender.
  • Single measurements may be used to screen for nutritional risk, but have limited use in determining growth patterns and should not be used as diagnostic criteria.
  • Plotting and tracking serial weight and length measurements can help to identify children with growth patterns that may warrant further investigation.
Weight Status Cut-off Criteria12

Complete healthy lifestyle record

It is important that both providers and patients/families monitor progress towards all ‘agreed-on’ healthy lifestyle goals. Use the Healthy Lifestyle Record to document the patient’s visit, and to summarize the ‘agreed-on’ goals and subsequent plan of action. This Record can be filed in the patient’s chart and referred to during follow-up visits to continue discussions about healthy lifestyle choices.
