Interdisciplinary Management of Cystic Fibrosis Patients

By Patricia J. Settle, MS, RD Pediatric Pulmonary Center Department of Pediatrics University of Arizona College of Medicine

Improving Nutrition is a Team Effort

It is important for the entire CF team to:  Be educated on the importance of nutrition  Emphasize the importance of nutrition But also to understand that the nutritional aspects of CF care often result in concurrent psychosocial family issues

Food is an Integral Part of Our Lives

In addition to meeting caloric needs, we use food for:

 Comfort   Expressions of emotion Reward   Punishment Socialization

It becomes very complex when we try to use food as part of a CF treatment plan, because we use food to meet so many other needs besides nutrition.

Case Study - Failure to Thrive

 Maggie K is a 23 month old child. Maggie was diagnosed with cystic fibrosis at age 6 months with symptoms of chronic cough and failure to thrive. She is the only child of an accountant and a stay- at- home Mom. Both sets of grandparents live close by and are involved in Maggie's care. Maggie was started on standard CF nutrition therapies including pancreatic enzymes, vitamins, and high calorie infant formula.

Case Study - FFT

 Maggie’s mother relates that she will only eat a very few foods such as hot dogs, pizza, and ice cream. She prefers to drink liquids such as juice and tea to milk. Mother states that meal times have become "very stressful.” Maggie refuses to sit at the table and "screams" when she is given any foods she is not familiar with. Mrs. K states "I am so worried about Maggie's weight and her eating." She admits that she wakes up at night and thinks about Maggie and her diet. She also states that she does not allow Maggie to play with other children or attend preschool because "she might get sick.”

Another Family Stress: High Energy CF Diets

Various studies show adherence to a high energy diet in children is between 16% and 50% Age Study

Tomezski, 1992 Stark, 1995 Stark, 1997 Anthony, 1998 5-10 2-5 6-12 7-12 23%

% Adherent

20% 50% 16%

Why Are Adherence Rates so Low?

Adherence to a high energy diet is hard because CF nutritional guidelines:

 Are just one part of complex treatment regimes  Are time consuming to plan  Require extensive lifestyle change  Require long-term change  May be conflict with eating patterns of other family members  Are often not associated with immediate feedback

Why Are Adherence Rates so Low?

 Tend to blow the “nutrition issue” out of proportion  Force parents into treating the CF child “with special care” instead of equally with siblings  Complicates normalization of family life and meal times with respect to food choices  Presents challenge for parents to maintain their own weight goals  Interferes with the development of a child’s autonomy in eating

What We Know

CF Children, ages 6 months to 12 years, consume  100% of the Daily Recommended Intake (DRI)  But not the 110%-200% required by the CFF Recommendations  Are psychosocial issues a factor in our inability to meet the CFF Recommendations ?

Overview of Behavioral Issues

  

Behaviors Associated With Children Behaviors Associated With Parents Strategies for Behavioral Modification

Sam, a typical CF child

Take Sam:

 Constantly asked, in a whiny voice, how much more he had to eat  Argued and negotiated each bite with parents  Tried to distract parents by telling long stories to delay eating  Complained of being full from beginning of meal

Sam’s Parents

 Used coaxing to encourage Sam to eat  Turned eating into a game: counting bites, chanting “Go, Go, Go!”  Gave Sam their full attention when he was NOT eating  When Sam was eating, the parents used the opportunity to talk to each other or Sam’s brother

Typical CF Child Behaviors

 Dawdling  Excessive talking and/or chewing  Complaining and whining  Arguing or negotiating about food  Prolonging mealtime, especially by talking in an attempt to distract parents from focusing on the child’s eating  Starting altercations with siblings

Typical CF Parent Behaviors

 Coaxing or coercing child into eating  Typically focusing all the attention on the CF child in an attempt to get the child to eat more. The more the child resists, the more attention the child gets.

 Often turning their attention to other children or each other only when the CF child is engaged in eating because it is the first time they feel able to divert their attention away from the CF child

Typical CF Parent Behaviors

The main strategy parents have is to keep the child at the table longer. This leads to higher rates of negative child behaviors and increased parent behaviors Parents often make a second meal to accommodate the CF child

Comparison of Child Behaviors

Children with CF and healthy peers engage in the same pattern of behavior during a meal. In the second half of the meal, children of both groups:  Eat less  Refuse food more  Leave the table more  Are more noncompliant

However,

children with CF engage in these behaviors at twice the rate of children without CF

Comparison of Parent Behaviors

Parents of children with and without CF try similar strategies to encourage eating and show the same pattern of increasing their efforts in the second half of the meal:  More commands  More coaxing  More feeding  More physical prompts However, parents of children with CF are engaging in these behaviors twice as much as parents of children without CF

CF Parent Feelings

Parents with CF children feel:

 Tremendous pressure to push their child to eat large amounts of food when the child doesn’t feel like eating  Fearful that that the child's not eating will “hurt” the child’s health

CF Parent Feelings

 Concerned that physicians will think parents are not following through on nutrition  Frustrated and exhausted for trying so hard  Defeated when the child cannot or will not comply  Worried about the effects of the mealtime stresses on other siblings

Related Observations

 Many parents of CF children did not have specific caloric goals – the more food the better – there is never a stopping point  Many parents increased caloric intake by increasing food volume, not adding calorically dense foods

Common Misconceptions

Myths or family bias that may have crept into the feeding situation:

 Families thinking a low fat diet is good  Parents feeling guilty about the number of “pills” (antibiotics, vitamins, acid blockers, appetite stimulants, enzymes) a child has to take, thus they give snacks that do not require enzymes

Common Misconceptions

 Parents believing that increasing enzyme dose means their child is more ill not that the child is growing or eating more food or that the food is higher in fat content

Making Nutrition Education Behavioral

 Set goals and gradually increase calories one meal at a time so parents and kids know when to stop and can feel good at the end of a meal  Provide individual suggestions of food choices and boosters based on child’s usual intake and preferences  Provide feedback on progress

Making Nutrition Education Behavioral

Start With Snacks

 Most parents are not routinely giving 2-3 snacks a day  Even if giving snacks, most are not giving the most calorically dense foods  It is easy to increase calories through snacks because snacks can be given throughout the day  Snacks are not as stressful as meals because they usually do not require preparation (“quick and easy”)

Making Nutrition Education Behavioral

 If more calories are needed after increasing snacks, then chose to augment the meal that has the lowest number of calories and/or the meal the family identifies as the easiest to target

Sometimes a Referral is Needed

Typical child behaviors and parenting strategies may :  Be insufficient and create barriers  Inadvertently reinforce not eating – giving attention to children when they are engaged in behaviors incompatible with eating such as dawdling, pouting, complaining, excessive talking, leaving the table

Behavioral Intervention Needed

When parents consistently express concern about child behaviors during meals, it is helpful to equip parents with extra skills to enable them to work more effectively with their children

Behavioral Intervention

Provide behavioral skills in addition to presenting nutritional recommendations

Examples:  Teach parents to set limits on meal length  Provide reward for appropriate eating such as compliments, attention, and activities  Ignore behaviors incompatible with eating (this is hard)

Behavioral Modification

 Reinforcement  Setting Rules  Praise positive eating behavior  Ignore negative eating behavior  Contingent Privileges  Shaping Behavior  Reward system  Behavioral Contracting

Reinforcement

Reinforcement - An event that makes the behavior that precedes more likely to occur in the future

It can be:  Positive: A compliment, hug, pat on the back  Negative: A scolding, nagging  Verbal  Physical

Setting Mealtime Rules

 A rule clearly states IN ADVANCE a relationship between a specific behavior and a specific consequence  At meals, rules are used for things like getting up and leaving the table before eating the required amount of food  A reason for the rule should be given like it is important that you eat your dinner to grow and to stay strong and healthy  Parents should be consistent with rules

Mealtime Rules

 Rules should be not be presented at meal time. This prevents the parent from being drawn into a negotiation about the rule at the time a child has misbehaved while eating  The parent should sit down with the child at a time other than a mealtime, state the rule simply, and provide the reason for it. The child should be asked to repeat the rule back to the parent to make sure the rule and consequences do not come as a surprise to the child

Praising

A parent’s attention is a valuable reward to a child.

Through intervention, parents are taught to notice and compliment behaviors that are compatible with eating

 Listening and following parent’s instructions  Taking bites  Taking one bite after another  Chewing and swallowing more quickly  Loading their fork while talking  Eating a bite of food before talking

Praising

Praising

 Increases child’s desirable behaviors  Teaches child what a parent likes  Motivates child to please the parent •

How to provide praise:

   Describe specifically what child is doing that the parent likes Actively compliment the child often Be timely – provide praise immediately when child does things the parent likes

Praising Statements

“I really like the way you take a bite, talk, and then take another bite.” “I like the way you are sitting up in your chair and eating.” “I enjoy meals when you are eating so well and we can discuss your day while we eat.” The parent should be encouraged to praise the child in a way that is comfortable and natural to both the parent and child. It may seem uncomfortable or awkward at first and may take some time to find the best style for parent and child.

Ignoring

Behaviors parents are taught to ignore:

 Excessive talking or story telling that interrupts eating for more than 10 seconds  Complaints about food or amount  Whining  Child sitting without taking bites  Child chewing for prolonged time  “Goofing around”

Ignoring

When using ignoring, parents should:

 Continue conversations with spouse and other children  Be ready to give attention to the CF child immediately if he engages in a desirable behavior

Timing Is Very Important!

Contingent Privileges

 The awarding of privileges to the child for meeting his calorie/meal goal  Giving child something he desires for doing something good for himself (eating sufficient calories)  One-to-one time with a parent doing an activity of the child’s choice  Access to video games  TV viewing

Contingent Privileges

The privilege system will not work if:  The awarding of the privilege is more important to the parent than to the child  The child does not have a vested interest in the reward and would rather forego award than eat  The parent cannot be consistent in awarding privileges

Behavioral Contracting

 Formalizes the use of contingency management  Defines the behavior that is to occur  Defines the consequences that will be delivered, by who and when

Energy Contract

This week, I agree to: 1.

2.

3.

Date: __________________ Get more energy at snack, breakfast, and lunch by eating the food my Mom or Dad gives me.

Eat the same amount of food at dinner. My Mom and Dad will tell me how much I need to eat.

Eat my meals within the time limit. My parents will tell me how much time I have to eat my meals. When the time is up, they will take away my plate.

If I work really hard and meet my energy goals, then my parents agree to let me choose one of the activities written here: ______________________________ ______________________________ My signature: _________________________ My parent’s signature: ____________________________

Shaping

The gradual attainment of a target behavior through the rewarding of successive steps that gradually build upon one another    Food acceptance is increased Calorie goals are broken down by meal so only one meal is targeted each week Calorie goals are gradually increased each week until the end goal is achieved    Start with small amount of food on plate Child needs to taste (put to tongue) Child needs to take one bite

Provide Emotional Support

• Explore sources of parental anxiety/depression • Relaxation techniques or psychotherapy • Provide calm, confident environment (hard if child is at risk -- paradox) • Help families feel supported to offset helpless or fatalistic feelings

Adolescent and Adult Issues

 Adolescents and adults should self-monitor to judge whether energy needs are obtainable orally  Contracting can be with healthcare providers instead of a parent  Patients should set their own goals that are small, reasonable and gradually build over time  Patients should be encouraged to self-reward  Families experience reduced stress once adolescents can drive to go out for meals and siblings mature and understand the demands of CF on their sibling

Issues Specific to Adolescents

Allan – Age 17

“I had a hang-up for the longest time about taking my enzymes in front of other people. I never wanted to stand out or be different from the other kids at school. So sometimes I skipped taking them altogether. It got to the point that the greasy, high-calorie food in the cafeteria was really causing me problems with malabsorption. “Dealing with gas and bloating was even more embarrassing. So I decided it was worth trying to answer questions about why I take enzymes and to take them before I ate. It turned out that it wasn’t a big deal. No one was turned off that I took them and I felt a lot better.”

Issues Specific to Young Adults

James – Age 19

“I think one of the things that was hard for me to deal with was that lots of people thought I was younger than I really was in high school. I was shorter and smaller than most everyone else. I was really worried, too, that I wouldn’t grow or reach puberty when everyone else did. I hated being different.

“What helped me adjust was I really made an effort to eat a lot and keep my weight up. I wanted to do everything I could to help myself grow. Finally, I grew some and was just about as tall as some people in my class. And even though I was still little, I joined the swim team and did pretty well. Just getting into something I liked doing helped me feel a lot better about myself.”

Case Studies – Parent Perspective

Felicia

“The Poster Child”  Makes parent feel successful  Has hunger, eats well, is compliant  Experiences typical adolescent behavior and responds positively to input by healthcare providers

Andrew

“The Problem Child”  Makes parent feel like a failure  Is never hungry, doesn’t eat, non-compliant  Apathetic to continued input and education from healthcare providers

Observation of Child Behaviors

Meals in families with a CF child tend to be excessively long
