Behavioral intervention to improve calorie intake of children with cystic fibrosis: treatment versus wait list control

Nutritional counseling in childhood and adolescence: a systematic review

Healthy eating habits are the basis for good health status, especially for children and adolescents, when growth and development are still ongoing. Nutrition educational programs are essential to prevent and treat chronic diseases. Nutritional counseling (NC), as a collaborative process between the counselor and the client process, could help to achieve better outcomes. This review aims to collect information about the utilization of NC during childhood and adolescence and to highlight its possible impact on adherence/compliance rates, nutrition knowledge, status and dietary intake. The methods applied in this systematic review followed the instruction of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The search in PubMed/Medline, Scopus, Web of Science, LILACS, and Science Direct included observational or randomized studies. RoB 2.0 and Robins-I tools was used for the risk of bias assessment in randomized and non-randomized studies, respectively. The quality of evidence was checked by the Mixed Methods Appraisal Tool system. A total of 21 articles were selected, computing 4,345 individuals. 11 achieved at least 4 stars quality level. The highest risk of bias for randomized studies was related to the randomization process. 42.9% of non-randomized studies had some concerns of bias, mainly because of a lack of control of all confounding factors. Different strategies of NC were used in children and adolescents with positive results for health or diseases. NC strategies can be effectively used in children and adolescents. In general, NC showed benefits in pediatrics age for anthropometric or body composition parameters, dietary intake, nutrition knowledge and physical activity improvement. Performing NC in pediatrics is challenging due to the counseling strategies that must be adapted in their contents to the cognitive ability of each age. More structured research must be done focused on this population. Investments in healthy eating behaviors in pediatrics can lead to better health outcomes in the future population with substantial benefits to society.

Evidence to support treatment options for children with swallowing and feeding disorders: A systematic review

PURPOSE

A rise in pediatric patients with swallowing and feeding problems has resulted in increased interest in multidisciplinary treatments to address these issues. This evidence based systematic review (EBSR) examined the published evidence for the use of common strategies used by clinicians across disciplines to treat pediatric swallowing and feeding problems.

METHODS

A systematic search of 10 electronic databases was completed to identify relevant, peer reviewed literature published in English prior to December 2015 reporting original data that addressed at least one of the five identified clinical questions.

RESULTS

Sixty-one studies of varying methodological quality were included. The majority of the included studies (60/61) focused on the use of behavioral therapies to remediate swallowing and feeding disorders in children and reported mixed findings across all of the targeted outcomes.

CONCLUSION

There is insufficient quantity of evidence to determine the effects of oral motor, sensory, and pharmaceutical therapies on functional feeding outcomes in pediatric populations. A larger body of phase 1 evidence is available that establishes the efficacy of behavioral strategies to treat some swallowing and feeding difficulties in small cohort and single subject studies. This analysis identified limited high quality (phase 4) research articles that establish the efficacy and benefit of joint nutrition and behavior intervention programs and systematic desensitization and operant conditioning behavioral therapy approaches to improve functional feeding and swallowing outcomes in children.

Strategies to optimize treatment adherence in adolescent patients with cystic fibrosis

While development of new treatments for cystic fibrosis (CF) has led to a significant improvement in survival age, routine daily treatment for CF is complex, burdensome, and time intensive. Adolescence is a period of decline in pulmonary function in CF, and is also a time when adherence to prescribed treatment plans for CF tends to decrease. Challenges to adherence in adolescents with CF include decreased parental involvement, time management and significant treatment burden, and adolescent perceptions of the necessity and value of the treatments prescribed. Studies of interventions to improve adherence are limited and focus on education, without significant evidence of success. Smaller studies on behavioral techniques do not focus on adolescents. Other challenges for improving adherence in adolescents with CF include infection control practices limiting in-person interactions. This review focuses on the existing evidence base on adherence intervention in adolescents with CF. Future directions for efforts to optimize treatment adherence in adolescents with CF include reducing treatment burden, developing patient-driven technology to improve tracking, communication, and online support, and rethinking the CF health services model to include assessment of individualized adherence barriers.

Web-Based Intervention for Nutritional Management in Cystic Fibrosis: Development, Usability, and Pilot Trial

OBJECTIVES

Usability and pilot testing of a web intervention (BeInCharge.org [BIC]) of behavior plus nutrition intervention for children with cystic fibrosis (CF) ages 4-9 years.

METHODS

Think Aloud methodology was used with five mothers to assess usability and refine the intervention. A pilot trial was then conducted with 10 mothers of children with CF ages 4-9 years randomized to the web-based BIC or a Standard Care Control (STC). Change in weight gain for each group was compared in a pre-to-post design.

RESULTS

Mothers rated the usability and clarity of BIC highly. The pilot trial showed children of mothers who received BIC had a significant change in weight pre-to-post-treatment (0.67 kg, p = .04). Change for the STC was not significant (0.41 kg, p = .10).

CONCLUSIONS

A web-based behavior plus nutrition intervention appears promising in increasing weight gain in children with CF.

The Cost of a Healthier Diet for Young Children With Type 1 Diabetes Mellitus

OBJECTIVE

This study used a market-basket approach to examine the availability and cost of a standard food shopping list (R-TFP) vs a healthier food shopping list (H-TFP) in the grocery stores used by a sample of 23 families of young children with type 1 diabetes mellitus (T1DM).

METHODS

The researchers used frequency counts to measure availability. The average cost of the R-TFP and H-TFP was compared using paired t test.

RESULTS

Small or independent markets had the highest percentage of missing foods (14%), followed by chain supermarkets (3%) and big box stores (2%). There was a significant difference in average cost for the R-TFP vs the H-TFP ($324.71 and $380.07, respectively; P < .001).

CONCLUSIONS AND IMPLICATIONS

Families may encounter problems finding healthier foods and/or incur greater costs for healthier foods. Nutrition education programs for T1DM need to teach problem solving to help families overcome these barriers.

Motivating adherence among adolescents with cystic fibrosis: youth and parent perspectives

As advances in the care of individuals with cystic fibrosis (CF) have resulted in improved survival, therapeutic regimens for treatment of CF have become increasingly complex. This high treatment burden poses challenges to chronic disease self-management, particularly amongst adolescents. The aim of this qualitative study was to understand the barriers and facilitators of adherence to chronic CF therapies as perceived by adolescents with CF and their parents. In a series of structured interviews with 18 youth and their parents, we explored issues related to daily routines, youth and parental roles regarding chronic therapy, and motivators for adherence. All interviews were audio-recorded and coded for themes and patterns. Reported barriers to adherence included time pressures, competing priorities, heightened awareness of disease trajectory, privacy concerns, and lack of perceived consequences from non-adherence. Identified facilitators for adherence included recognizing the importance of therapies, developing strong relationships with care teams, establishing structured routines, and focusing on shifting responsibilities from a parent to their adolescent child. The themes uncovered by these interviews identify areas for intervention and support by clinical programs seeking to improve adherence and self-management strategies for adolescents with CF.

Self-management education for cystic fibrosis

BACKGROUND

Self-management education may help patients with cystic fibrosis and their families to choose, monitor and adjust treatment requirements for their illness, and also to manage the effects of illness on their lives. Although self-management education interventions have been developed for cystic fibrosis, no previous systematic review of the evidence of effectiveness of these interventions has been conducted.

OBJECTIVES

To assess the effects of self-management education interventions on improving health outcomes for patients with cystic fibrosis and their caregivers

SEARCH METHODS

We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register (date of the last search: 22 August 2013).We also searched databases through EBSCO (CINAHL; Psychological and Behavioural Sciences Collection; PsychInfo; SocINDEX) and Elsevier (Embase) and handsearched relevant journals and conference proceedings (date of the last searches: 01 February 2014 ).

SELECTION CRITERIA

Randomised controlled trials, quasi-randomised controlled trials or controlled clinical trials comparing different types of self-management education for cystic fibrosis or comparing self-management education with standard care or no intervention.

DATA COLLECTION AND ANALYSIS

Two authors assessed trial eligibility and risk of bias. Three authors extracted data.

MAIN RESULTS

Four trials (involving a total of 269 participants) were included. The participants were children with cystic fibrosis and their parents or caregivers in three trials and adults with cystic fibrosis in one trial. The trials compared four different self-management education interventions versus standard treatment: (1) a training programme for managing cystic fibrosis in general; (2) education specific to aerosol and airway clearance treatments; (3) disease-specific nutrition education; and (4) general and disease-specific nutrition education. Training children to manage cystic fibrosis in general had no statistically significant effects on weight after six to eight weeks, mean difference -7.74 lb (i.e. 3.51 kg) (95% confidence interval -35.18 to 19.70). General and disease-specific nutrition education for adults had no statistically significant effects on: pulmonary function (forced expiratory volume at one second), mean difference -5.00 % (95% confidence interval -18.10 to 8.10) at six months and mean difference -5.50 % (95% confidence interval -18.46 to 7.46) at 12 months; or weight, mean difference - 0.70 kg (95% confidence interval -6.58 to 5.18) at six months and mean difference -0.70 kg (95% confidence interval -6.62 to 5.22) at 12 months; or dietary fat intake scores, mean difference 1.60 (85% confidence interval -2.90 to 6.10) at six months and mean difference 0.20 (95% confidence interval -4.08 to 4.48) at 12 months. There is some limited evidence to suggest that self-management education may improve knowledge in patients with cystic fibrosis but not in parents or caregivers. There is also some limited evidence to suggest that self-management education may result in positively changing a small number of behaviours in both patients and caregivers.

AUTHORS' CONCLUSIONS

The available evidence from this review is of insufficient quantity and quality to draw any firm conclusions about the effects of self-management education for cystic fibrosis. Further trials are needed to investigate the effects of self-management education on a range of clinical and behavioural outcomes in children, adolescents and adults with cystic fibrosis and their caregivers.

Psychological interventions for individuals with cystic fibrosis and their families

BACKGROUND

With increasing survival estimates for individuals with cystic fibrosis, long-term management has become an important focus. Psychological interventions are largely concerned with adherence to treatment, emotional and social adaptation and health-related quality of life. We are unaware of any relevant systematic reviews.

OBJECTIVES

To determine whether psychological interventions for people with cystic fibrosis provide significant psychosocial and physical benefits in addition to standard medical care.

SEARCH METHODS

Studies were identified from two Cochrane trials registers (Cystic Fibrosis and Genetic Disorders Group; Depression, Anxiety and Neurosis Group), Ovid MEDLINE and PsychINFO; unpublished trials were located through professional networks and Listserves. Most recent search of the Cystic Fibrosis and Genetic Disorders Group's register: 19 December 2013.Most recent search of the Depression, Anxiety and Neurosis Group's register: 12 November 2013.

SELECTION CRITERIA

Randomised controlled studies of a broad range of psychological interventions evaluating subjective and objective health outcomes, such as quality of life or pulmonary function, in individuals of all ages with cystic fibrosis and their immediate family. We were interested in psychological interventions, including psychological methods within the scope of psychotherapeutic or psychosomatic mechanism of action (e.g. cognitive behavioural, cognitive, family systems or systemic, psycho-dynamic, or other, e.g. supportive, relaxation, or biofeedback), which were aimed at improving psychological and psychosocial outcomes (e.g. quality of life, levels of stress or distress, psychopathology, etc.), adaptation to disease management and physiological outcomes.

DATA COLLECTION AND ANALYSIS

Three authors were involved in selecting the eligible studies and two of these authors assessed their risk of bias.

MAIN RESULTS

The review includes 16 studies (eight new studies included in this update) representing data from 556 participants. Studies are diverse in their design and their methods. They cover interventions with generic approaches, as well as interventions developed specifically to target disease-specific symptoms and problems in people with cystic fibrosis. These include cognitive behavioural interventions to improve adherence to nutrition or psychosocial adjustment, cognitive interventions to improve adherence or those associated with decision making in lung transplantation, a community-based support intervention and other interventions, such as self-hypnosis, respiratory muscle biofeedback, music therapy, dance and movement therapy, and a tele-medicine intervention to support patients awaiting transplantation.A substantial proportion of outcomes relate to adherence, changes in physical status or other specific treatment concerns during the chronic phase of the disease.There is some evidence that behavioural interventions targeting nutrition and growth in children (4 to 12 years) with cystic fibrosis are effective in the short term. Evidence was found that providing a structured decision-making tool for patients considering lung transplantation improves patients' knowledge of and expectations about the transplant, and reduces decisional conflict in the short term. One study about training in biofeedback-assisted breathing demonstrated some evidence that it improved some lung function measurements. Currently there is insufficient evidence for interventions aimed at other aspects of the disease process.

AUTHORS' CONCLUSIONS

Currently, insufficient evidence exists on psychological interventions or approaches to support people with cystic fibrosis and their caregivers, although some of the studies were promising. Due to the heterogeneity between studies, more of each type of intervention are needed to support preliminary evidence. Multicentre studies, with consequent funding implications, are needed to increase the sample size of these studies and enhance the statistical power and precision to detect important findings. In addition, multicentre studies could improve the generalisation of results by minimizing centre or therapist effects. Psychological interventions should be targeted to illness-specific symptoms or behaviours to demonstrate efficacy.

Examining mealtime behaviors in families of young children with type 1 diabetes on intensive insulin therapy

This study examined mealtime behaviors in families of young children with type 1 diabetes (T1DM) on intensive insulin therapy. Behaviors were compared to published data for children on conventional therapy and examined for correlations with glycemic control. Thirty-nine families participated and had at least three home meals videotaped while children wore a continuous glucose monitor. Videotaped meals were coded for parent, child, and child eating behaviors using a valid coding system. A group difference was found for child request for food only. There were also associations found between children's glycemic control and child play and away. However, no associations were found between parent and child behaviors within meals and children's corresponding post-prandial glycemic control. Results reinforce existing research indicating that mealtime behavior problems exist for families of young children even in the context of intensive therapy and that some child behaviors may relate to glycemic control.

Does eating during television viewing affect mealtimes in young children with type 1 diabetes mellitus?

This study looks for differences in mealtime characteristics and glycemic control for young children with type 1 diabetes who either eat with television (TV) viewing or without TV viewing. Sample size is 24 families (mean child age=5.2, SD=1.0 years). Meals with TV lasted 6 minutes longer than meals without TV. Meals with TV were associated with greater fat intake and higher average glucose levels, but not with greater intake of calories, carbohydrates, or more child bites. This study suggests relations between TV viewing and some negative outcomes for young children, but more research is needed to determine causation.

Childhood feeding difficulties: a randomized controlled trial of a group-based parenting intervention

BACKGROUND

Difficulty with feeding is common during early childhood. Behavioral techniques have shown considerable utility for difficult feeding, although large-scale studies of behavioral parenting interventions with typically developing young children, and in group formats, are limited.

OBJECTIVE

The current study aimed to evaluate the efficacy of a group-based, behavioral family intervention for typically developing healthy children with problem eating via a fully randomized 2-group design.

METHODS

: Ninety-six families of children aged 1.5 to 6 years with feeding difficulties participated in a trial of Hassle Free Mealtimes Triple P (A. Morawska and M.R. Sanders, unpublished data, 2008) in regional and metropolitan Queensland (Australia).

RESULTS

Results support the utility of a group-based behavioral parenting program for childhood feeding issues, with significant improvements to the mealtime and general behavior of target children, the mealtime and general practices of parents, parental confidence and cognitions, compared with a waitlist control. Six-month follow-up data and clinical and reliable change indices support the intervention's utility. Parents were also highly satisfied with the program.

CONCLUSION

The current study provides evidence of the efficacy of a group-based behavioral family intervention for mealtime difficulties, including observational and more extended outcome measures. Future directions and clinical implications of this research are discussed.

Evaluation of a group-based behavioral intervention to promote adherence in adolescents with inflammatory bowel disease

OBJECTIVE

To pilot test the feasibility and acceptability of a family-based group behavioral intervention and to improve medication adherence in adolescents diagnosed with inflammatory bowel disease.

METHODS

Participants were 40 adolescents aged 11-18 years diagnosed with inflammatory bowel disease and their primary caregivers, who were randomized to either a four-session Family-Based Group Behavioral Treatment or Usual Care over a 6-week period. Adherence was measured using a multi-method, multi-informant assessment involving caregiver-report and patient-report, pill count data, and electronic monitoring.

RESULTS

Adherence rates ranged from 66 to 89% for 6-mercaptopurine/azathioprine and 51 to 93% for mesalamine across assessment methods. The intervention was feasible, as evidenced by the 99% treatment session attendance rate, and acceptable based on patient and caregiver report. Repeated measures analysis of variance tests revealed nonsignificant differences between the conditions from baseline to post-treatment assessments for pill count, electronic monitor, and primary caregiver-reported adherence (P's>0.05). There was a statistically significant improvement in patient-reported mesalamine adherence represented by a significant main effect for Condition (F=22.24, P<0.01; δ=0.79) and Condition×Time interaction (F=13.32, P<0.05; δ=0.69).

CONCLUSION

Findings suggest potential for use of behavioral intervention to improve medication adherence in this population. This intervention may be more effective with more complex regimens (e.g. multiple doses per day) such as those prescribed with mesalamine. Further research is needed to examine this type of intervention in more diverse samples with more active disease. Use of alternative adherence measurement approaches, including electronic pill boxes and/or real-time self-report (e.g. by text messaging, electronic diaries, etc.) is also recommended.

Self-management education for cystic fibrosis

Pediatric feeding disorders: a quantitative synthesis of treatment outcomes

A systematic review of the literature regarding treatment of pediatric feeding disorders was conducted. Articles in peer-reviewed scientific journals (1970-2010) evaluating treatment of severe food refusal or selectivity were identified. Studies demonstrating strict experimental control were selected and analyzed. Forty-eight single-case research studies reporting outcomes for 96 participants were included in the review. Most children presented with complex medical and developmental concerns and were treated at multidisciplinary feeding disorders programs. All studies involved behavioral intervention; no well-controlled studies evaluating feeding interventions by other theoretical perspectives or clinical disciplines met inclusion criteria. Results indicated that behavioral intervention was associated with significant improvements in feeding behavior. Clinical and research implications are discussed, including movement toward the identification of key behavioral antecedents and consequences that promote appropriate mealtime performance, as well as the need to better document outcomes beyond behavioral improvements, such as changes in anthropometric parameters, generalization of treatment gains to caregivers, and improvements in nutritional status.

The effects of an intensive behavior and nutrition intervention compared to standard of care on weight outcomes in CF

Inadequate intake and suboptimal growth are common problems for patients with CF and a critical target for intervention. The purpose of this study was to compare the growth outcomes of children with CF who participated in a randomized clinical trial to improve energy intake and weight to children with CF receiving standard of care during the same time period. Our primary outcome was change in body mass index z-score (BMI z-score) over 2 years. An exploratory outcome was forced expiratory volume at 1-sec (FEV(1) ) over 2 years. Participants were children ages 4-12 with CF, who participated in a randomized clinical trial of behavior plus nutrition intervention versus nutrition education alone, and a matched Comparison Sample receiving standard of care drawn from the Cystic Fibrosis Foundation (CFF) Registry. Children in the Clinical Trial Group (N=67) participated in a 9-week, nutrition intervention and were followed at regular intervals (3, 6, 12, 18, and 24 months) for 2 years post-treatment to obtain anthropometric and pulmonary function data. For each child in the Comparison Sample (N=346), these measures were obtained from the CFF Registry at matching intervals for the 27-month period corresponding to the clinical trial. Over 27 months, children in the Clinical Trial Group (the combined sample of the behavior plus nutrition and the nutrition alone) demonstrated significantly less decline in BMI z-score, -0.05 (SD=0.68, CI= -0.23 to 0.13), as compared to children in the Comparison Sample, -0.21 (SD=0.67, CI= -0.31 to -0.11). No statistically significant differences were found for decline in FEV(1) between children in the Clinical Trial Group and the Comparison Sample. The key implication of these findings is that intensive behavioral and nutritional intervention is effective and needs to be adapted so that it can be broadly disseminated into clinical practice.

Mealtime problems predict outcome in clinical trial to improve nutrition in children with CF

Better growth and nutritional status is strongly associated with better pulmonary function and survival in children with CF. Behavioral intervention is an efficacious treatment approach for improving calorie intake and weight gain in children with CF; and recently has been shown to facilitate maintenance of daily energy intake at 120% of the healthy population over a 2-year period. However, no study to date has examined factors that predict outcome with behavior intervention to promote weight gain in CF. The objectives of this study were to examine the influence of nutritional status, mealtime behavior problems, and maternal depressive symptoms on calorie intake and weight gain following participation in a randomized trial to improve nutritional status in cystic fibrosis. Sixty-seven children, aged 4-12 years with cystic fibrosis participated in a clinical trial targeting calorie and weight increases. Participants completed baseline measures of mealtime behavior problems, maternal depression, and fat absorption, and baseline and post-treatment caloric intake and weight. Assignment to behavioral group (R(2) change = 0.17), lower frequency of mealtime behavior problems (R(2) change = 0.11), and higher maternal depression (R(2) change = 0.06) predicted greater calorie increase baseline to post-treatment. Assignment to behavioral group (R(2) change = 0.09), higher baseline weight (R(2) change = 0.10), fat absorption (R(2) change = 0.02), and lower frequency of mealtime behavior problems (R(2) change = 0.06) predicted greater weight gain baseline to post-treatment. Less frequent mealtime behavior problems led to better calorie intake and weight gain in a 9-week clinical trial of behavior intervention and nutrition education to improve nutritional status in cystic fibrosis. The key implication from these findings is that early referral to behavioral intervention as soon as growth deficits become a concern will likely yield the best nutritional outcomes.

Parent/Child training to increase preteens' calcium, physical activity, and bone density: a controlled trial

PURPOSE

To test effects of parent/child training designed to increase calcium intake, bone-loading physical activity (PA), and bone density.

DESIGN

Two-group randomized controlled trial.

SETTING

Family-based intervention delivered at research center.

SUBJECTS

117 healthy children aged 10-13 years (58.1% female, 42.7% Hispanic, 40.2% White). Ninety-seven percent of participants had at least one parent graduate from high school and 37.2 % had at least one parent graduate from a 4-year university.

INTERVENTION

Children and parents were randomly assigned to diet and exercise (experimental) or injury prevention (control) interventions. Children were taught in eight weekly classes how to engage in bone-loading PA and eat calcium-rich foods or avoid injuries. Parents were taught behavior management techniques to modify children's behaviors.

MEASURES

Measures at baseline and at 3, 9, and 12 months included 24-hour diet and PA recalls, and bone mineral density (BMD) by dual-energy x-ray absorptiometry.

ANALYSIS

Analysis of variance and generalized estimating equations (GEE) assessed group by time differences. Comparisons were conducted separately for boys and girls.

RESULTS

For boys, cross-sectional differences between experimental and control groups were achieved for 3- and 9-month calcium intake (1352 vs. 1052 mg/day, 1298 vs. 970 mg/day, p < .05). For girls, marginal cross-sectional differences were achieved for high-impact PA at 12 months (p < .10). For calcium intake, a significant group by time interaction was observed from pretest to posttest for the full sample (p = .008) and for girls (p = .006) but not for boys. No significant group by time differences in calcium were observed across the follow-up period. No group by time differences were observed for high-impact PA. Among boys, longitudinal group by time differences reached significance for total hip BMD (p = .045) and femoral neck BMD (p = .033), even after adjusting for skeletal growth. Similar differential increases were observed among boys for bone mineral content (BMC) at the hip (p = .068) and total body (p = .054) regions. No significant group by time interaction effects were observed for girls at any bone site for BMD. For BMC, control girls showed a significant increase (p = .03) in spine BMC compared to intervention girls.

CONCLUSION

This study demonstrated that parent/preteen training can increase calcium intake and attenuate the decline in high-impact PA. Results suggest that more powerful interventions are needed to increase activity levels and maximize bone mineral accrual during preadolescent years.

Family functioning at meals relates to adherence in young children with type 1 diabetes

AIMS

This study examined associations between mealtime family functioning, dietary adherence and glycaemic control in young children with type 1 diabetes mellitus (T1DM). We hypothesised that poorer family functioning would correlate with poorer dietary adherence and glycaemic control.

METHODS

Thirty-five families of children (M = 5.6 +/- 1.5 years) with T1DM had meals videotaped in their home, which were coded for family functioning according to the McMaster Interaction Coding System. Children's dietary adherence was assessed according to deviations from the prescribed number of carbohydrate units per meal and recommended carbohydrate intake levels per day. Glycaemic control was measured via 14 days of self-monitoring of blood glucose levels.

RESULTS

Findings demonstrated significant negative associations between children's dietary adherence and two dimensions of family functioning: Task Accomplishment (r=-0.43, P= 0.03) and Behavioral Control (r=-0.54, P= 0.00). Affect Management correlated negatively with the percent of blood glucose levels below the normal range (r=-0.33, P= 0.05). Eleven families (31%) of young children with type 1 diabetes demonstrated mealtime family functioning in the unhealthy range.

CONCLUSIONS

This was the first study to examine the relationship between mealtime family functioning and children's dietary adherence and glycaemic control in families of young children with T1DM. Previous research has found mealtime family functioning to be impaired in families of young children with T1DM when compared with families of children without diabetes. Research is needed to determine if family functioning and dietary adherence can be improved via specific family-based behavioural training around mealtimes.

Feeding problems reported by parents of young children with type 1 diabetes on insulin pump therapy and their associations with children's glycemic control

OBJECTIVE

Previous research demonstrated high rates of perceived mealtime behavior problems in families of young children with type 1 diabetes who were managed with conventional therapy. Because of new insulin regimens that offer greater flexibility, reexamination of mealtime behaviors is required. We assessed parent-reported mealtime behaviors in a sample of young children using an insulin pump. An additional aim was to evaluate the associations of two measures of parental feeding behavior with children's glycemic control.

METHODS

Primary caregivers of 31 young children (mean age = 5.0 +/- 1.3 yr) completed the Child Feeding Questionnaire (CFQ) and the Behavioral Pediatric Feeding Assessment Scale (BPFAS). Hemoglobin A1c (HbA1c) was used as a surrogate marker for children's glycemic control.

RESULTS

Children had a mean HbA1c of 7.8 +/- 0.64%. Mean CFQ - Restriction and Pressure to Eat scores were 3.1 +/- 0.94 and 2.0 +/- 0.88, respectively (range = 1-5). Mean BPFAS - Parent and Child scores were 16.0 +/- 4.3 (range = 10-50) and 44.9 +/- 9.3 (range = 25-125), respectively. Positive correlations were found between children's HbA1c levels and caregivers' reporting of frequency of child mealtime behavior problems.

CONCLUSIONS

Caregivers of young children on pump therapy report relatively low rates of mealtime behavior problems. However, correlations with children's HbA1c suggest that parent-child mealtime behaviors continue to relate to children's health outcomes. Research is needed to determine if changing mealtime interactions can improve children's glycemic control; items from the BPFAS and CFQ can offer targets to guide interventions.

Randomized clinical trial of behavioral intervention and nutrition education to improve caloric intake and weight in children with cystic fibrosis

OBJECTIVE

To evaluate the efficacy of a behavioral plus nutrition education intervention, Be In CHARGE!, compared with that of a nutrition education intervention alone on caloric intake and weight gain in children with cystic fibrosis and pancreatic insufficiency.

DESIGN

Randomized controlled trial.

SETTING

Cystic fibrosis centers in the eastern, midwestern, and southern United States.

PARTICIPANTS

Seventy-nine children aged 4 to 12 years below the 40th percentile for weight for age were recruited. Sixty-seven completed the intervention and 59 completed a 24-month follow-up assessment.

INTERVENTION

Comparison of a behavioral plus nutrition education intervention with a nutrition education intervention alone.

MAIN OUTCOME MEASURES

Primary outcomes were changes from pretreatment to posttreatment in caloric intake and weight gain. Secondary outcomes were changes from pretreatment to posttreatment in percentage of the estimated energy requirement and body mass index z score. These outcomes were also examined 24 months posttreatment.

RESULTS

After treatment, the behavioral plus nutrition education intervention as compared with the nutrition education intervention alone had a statistically greater average increase on the primary and secondary outcomes of caloric intake (mean, 872 vs 489 cal/d, respectively), percentage of the estimated energy requirement (mean, 148% vs 127%, respectively), weight gain (mean, 1.47 vs 0.92 kg, respectively), and body mass index z score (0.38 vs 0.18, respectively). At the 24-month follow-up, children in both conditions maintained an estimated energy requirement of around 120% and did not significantly differ on any outcomes.

CONCLUSIONS

A behavioral plus nutrition education intervention was more effective than a nutrition education intervention alone at increasing dietary intake and weight over a 9-week period. However, across the 24-month follow-up, both treatments achieved similar outcomes. Trial Registration clinicaltrials.gov Identifier: NCT00006169.

The efficacy of adherence interventions for chronically ill children: a meta-analytic review

OBJECTIVES

To provide quantitative information about the overall effectiveness of adherence interventions to improve adherence and health outcomes for children with chronic illnesses. To evaluate statistically the potential moderators.

METHODS

A meta-analysis was performed on 71 adherence intervention studies.

RESULTS

Weighted-mean effect size (ES) across all the adherence outcomes for group design studies was in the medium range (mean d = 0.58) and for single-subject design studies was in the large range (mean d = 1.44). The weighted mean ES across all health outcome measures for studies using group designs was in the medium range (mean d = 0.40) and for studies using single-subject designs was in the large range (mean d = 0.74).

CONCLUSIONS

Adherence interventions for children with chronic illnesses effectively increase adherence and result in some positive health benefits. Intervention and methodological variables had significant impact on ESs. High levels of heterogeneity characterized the data.

Evaluation of the nutrition counselling component of a fitness programme for children with disabilities

OBJECTIVE

To describe and evaluate the nutrition counselling component of a fitness programme for children with disabilities.

METHODS

Twenty-eight children with disabilities, ages 6-14 years, participated in a 16-week comprehensive fitness programme consisting of twice weekly exercise sessions, nutrition counselling and physical activity promotion education sessions. Nutrition sessions consisted of three individual and two group sessions. Individual nutrition goals were developed for each child using 3-day food intake diaries and parent interview. Body Mass Index (BMI) and progress towards nutrition goals were documented.

RESULTS

No significant BMI changes were recorded for the entire group (n=28) or a sub-group with a goal to decrease BMI (n=8). Most of the children made improvements in individual goals indicating improvements in healthy eating habits. This included eating the daily recommended amount of servings of each food group, trying new foods and limiting foods containing saturated and trans fats, sodium and sugar.

CONCLUSION

Short-term changes were noted in eating habits and behaviours during the 16-week fitness programme, although the effects did not influence overall BMI during the 16-week programme. Children with disabilities are at nutritional risk, and long-term follow-up is needed to determine if initial changes in parent-reported child eating behaviours will impact long-term nutrition, BMI and overall health.

Description of a standardized nutrition classification plan and its relation to nutritional outcomes in children with cystic fibrosis

OBJECTIVE

Better nutrition enhances lung function and increases survival for children with cystic fibrosis (CF). Therefore, we developed a standardized strategy to evaluate nutritional status and create individualized treatment plans to ensure that all patients received the same high-quality care in a busy CF Center.

METHODS

A quality improvement approach was undertaken to develop a novel nutrition classification strategy to identify and treat children with subtle manifestations of nutritional deficits in addition to those with obvious nutritional issues.

RESULTS

During the 15-month study period, the median body mass index (BMI) percentile increased from 35.2 (0-95.9) to 42.0 (0-97.7), p < .005. Additionally, the number of children with a BMI >or=50th percentile increased by 11.8%.

CONCLUSIONS

Adoption of a standardized approach to nutritional assessment and treatment led to significant improvement in nutritional outcomes of CF patients, demonstrating that systematic changes in clinical practice can improve clinical outcomes substantially over a short period of time.

Are children with type 1 diabetes consuming a healthful diet?: a review of the current evidence and strategies for dietary change

PURPOSE

The purpose of this study is to review the literature on usual dietary intake in children with type 1 diabetes (T1D) and to discuss approaches to promote dietary change with potential efficacy.

METHODS

Search strategies included a MEDLINE search for English-language articles that estimated usual dietary intake in children with T1D and a screening of the reference lists from original studies. The keywords used were diet, dietary intake, nutrition, type 1 diabetes, children, adolescents, and youth. Studies were included if they were observational, contained a sample of children with T1D, and estimated usual dietary intake.

RESULTS

Nine studies fulfilled the criteria (6 US, 3 European). Of the 4 studies with a control group, 3 reported that both total fat and saturated fat intake were higher in the children with T1D. Six studies examined the percent of total calories from saturated fat; mean intake ranged from 11 to 15%, exceeding ADA recommendations (< 7%). Fruit, vegetable, and fiber intakes were low among children with T1D. No prior studies have addressed dietary change in this population. The behavior-change literature suggests that nutrition education alone is unlikely to be adequate, but that incorporation of behavioral approaches offers potential efficacy in promoting healthful dietary change.

CONCLUSIONS

Children with T1D are not meeting dietary guidelines, and in some areas their diets are less healthful than children without diabetes. As these dietary behaviors may affect the risk of long-term complications, the incorporation of behavioral approaches promoting healthy eating into routine clinical practice is warranted.

Serum linoleic acid status as a clinical indicator of essential fatty acid status in children with cystic fibrosis

BACKGROUND

Children with cystic fibrosis (CF) and pancreatic insufficiency (PI) are at increased risk for essential fatty acid (EFA) deficiency.

OBJECTIVES

To investigate serum markers of EFA status in children with CF and PI and their association with growth, body composition, and lung function.

PATIENTS AND METHODS

Serum phospholipid fatty acid, growth, and forced expiratory volume at 1 second (FEV1, percentage predicted) status were assessed at baseline and 12 months in 77 children with CF and PI, 7 to 10 years old. Longitudinal mixed-effects models were used to compare associations of the triene:tetraene ratio (ratio of eicosatrienoic acid to arachidonic acid) and serum linoleic acid (as a molar percentage of total serum phospholipid fatty acids, or mol%) with the clinical outcomes. Controls for serum fatty acid were 23 healthy white age- and sex-matched children.

RESULTS

Children with CF and PI had higher median triene:tetraene ratio and lower linoleic acid than healthy controls. Depending on the triene:tetraene ratio cutoff point used (0.04 or 0.02), either 17% or 52% of the children with CF had EFA deficiency, respectively. Only linoleic acid was significantly and positively associated with z scores for weight, height, body mass index, upper arm muscle area, and FEV1 at baseline. Children with linoleic acid at 21 mol% or higher had significantly better growth and pulmonary status than those with lower concentrations.

CONCLUSIONS

Serum phospholipid linoleic acid at 21 mol% or higher was associated with better growth, body composition, and FEV1. No clinical outcome associations were found with the triene:tetraene ratio. These findings suggest that linoleic acid concentration was a more clinically relevant biomarker of EFA status than the triene:tetraene ratio in children with CF and PI. Further research is warranted to validate this specific percentage of linoleic acid cutoff point as a new recommendation for clinical use.

Psychological interventions for people with cystic fibrosis and their families

BACKGROUND

With increasing survival estimates for cystic fibrosis (CF) long-term management has become an important focus. Psychological interventions are largely concerned with adherence to treatment, emotional and social adjustments and quality of life. We are unaware of any relevant systematic reviews.

OBJECTIVES

Assess whether psychological interventions for CF provide significant psychosocial and physical benefits in addition to standard care.

SEARCH STRATEGY

Trials were identified from two Cochrane trial registers (CF and Genetic Disorders Group; Depression, Anxiety and Neurosis Group), Ovid MEDLINE and PsychINFO; unpublished trials were located through professional networks and Listserves. Most recent search: September 2007.

SELECTION CRITERIA

Randomised controlled trials of a broad range of psychological interventions in children and adults with CF and their immediate family.

DATA COLLECTION AND ANALYSIS

Two authors independently selected relevant trials and assessed their methodological quality.

MAIN RESULTS

The review includes 13 studies (five new at this update) representing data from 529 participants. Studies mainly assessed behavioural and educational interventions:1. gene pre-test education counselling for relatives of those with CF;2. biofeedback, massage and music therapy to assist physiotherapy;3. behavioural and educational interventions to improve dietary intake and airway clearance;4. self-administration of medication and education to promote independence, knowledge and quality of life; and5. systemic interventions promoting psychosocial functioning.A substantial proportion of outcomes were educational or behavioural relating to issues of adherence, change in physical status or other specific treatment concerns during the chronic phase of the disease. Some evidence was found for relative's acceptance of a genetic test for carrier status when using home-based rather than clinic-based information leaflets and testing. There is some evidence that behavioural interventions improve emotional outcomes in people with CF and their carers, and that psychoeducational interventions improve knowledge in the short term. There was no consistent effect on lung function, although one small study showed that biofeedback-assisted breathing re-training helped improve some lung function measurements. Some studies point to educational and behavioural interventions aiding nutrition and growth in people with CF. Currently there is insufficient evidence for interventions aimed at other aspects of the disease process.

AUTHORS' CONCLUSIONS

Currently no clear evidence exists on the best psychological interventions to help people with CF and their carers manage the disease. Trials of interventions to improve adherence to treatment are needed. Multicentre approaches, with consequent funding implications, will increase the sample size of trials and enhance the power and precision of their findings.

Evidence-based practice recommendations for nutrition-related management of children and adults with cystic fibrosis and pancreatic insufficiency: results of a systematic review

The Cystic Fibrosis Foundation established a process of systematic review of evidence to inform the development of clinical care guidelines and encourage evidence-based practice. The Subcommittee on Growth and Nutrition reviewed the evidence in two areas: energy intake and dosing for pancreatic enzyme replacement therapy. Evidence-based recommendations are presented here. Also, an ad hoc working group conducted a review of the literature and performed new analyses using the Cystic Fibrosis Foundation Patient Registry to update the recommendations for growth and weight-status monitoring. These Registry data-based recommendations are presented.

Observational assessment of family functioning in families with children who have type 1 diabetes mellitus

OBJECTIVE

Children with type 1 diabetes mellitus have a complex treatment regimen that includes insulin therapy and dietary requirements (e.g., matching insulin and carbohydrate intake). Previous research has shown that parents of children with type 1 diabetes mellitus report significant mealtime challenges and higher parenting stress compared to parents of healthy controls. The objective of the current study was to compare family functioning in children with type 1 diabetes mellitus (ages 2-8) to a matched, healthy control sample. Sixty-six families (33 diabetes; 33 controls) participated in a home visit at which their evening meal was videotaped. Tapes were then coded using the McMaster Interaction Coding System to objectively assess family functioning.

RESULTS

Results indicated that families in the diabetes group demonstrated significantly poorer family functioning in a majority of areas (communication, affect management, family roles, overall functioning) compared to the healthy control sample. Additionally, families with lower socioeconomic status and families of male children evidenced poorer overall family functioning for both groups.

CONCLUSIONS

Results also suggest that family-focused interventions for young children with type 1 diabetes should include components targeting family functioning in the areas of communication, affect management, and family roles.

Differences in family mealtime interactions between young children with type 1 diabetes and controls: implications for behavioral intervention

OBJECTIVE

We examine clinically relevant differences in family mealtime behaviors for young children with type 1 diabetes mellitus (T1DM) and matched controls.

METHODS

One hundred and eighteen families (46% boys; M age = 5.0, SD = 1.5 years) had at least three home meals videotaped and coded for family behaviors. Analyses had adequate statistical power to detect medium effects.

RESULTS

Parents of children with TIDM offered a higher rate and frequency of commands to eat than controls. As the meal progressed, all parents worked harder at controlling mealtimes, while children ate less. Behaviors associated with lower dietary adherence and poorer glycemic control occurred on average 9 min of a typical 19 min meal for children with TIDM.

CONCLUSIONS

When differences in family mealtime behaviors have been found in other pediatric groups (e.g., cystic fibrosis), the results have directly informed the development of effective interventions. The clinically relevant results of this study can be used to inform interventions for young children with TIDM.

Meta-analysis of psychological interventions to promote adherence to treatment in pediatric chronic health conditions

OBJECTIVE

To estimate the effectiveness of adherence-promoting psychological interventions for pediatric populations with chronic health conditions.

METHODS

A meta-analysis was conducted on 70 adherence-promoting psychological intervention studies among chronically ill youth using a weighted least squares approach and random effect model.

RESULTS

Medium effects sizes were found for the behavioral (mean d =.54, 95% confidence interval [CI] = 0.34-0.73, n = 10) and multi-component interventions (mean d =.51, 95% CI = 0.45-0.57, n = 46), while educational interventions displayed a small effect size with adherence (mean d =.16, 95% CI = 0.10-0.22, n = 23). Study designs incorporating pre-post comparisons yielded effect sizes approaching the medium range (mean d =.42, 95% CI = 0.36-0.48, n = 30).

CONCLUSIONS

Behavioral and multi-component interventions appear to be relatively potent in promoting adherence among chronically ill youth. Recommendations for future research and methodological issues are presented.

Can nutrition counselling be more behavioural? Lessons learned from dietary management of cystic fibrosis

Cystic fibrosis (CF) is a genetically-inherited disorder that results in energy imbalance. Undernutrition is common in children with CF and associated with poor health outcomes. To ensure optimal growth and nutrition, children with CF are recommended to consume 120–150% of the recommended daily allowance (RDA) for energy, but most studies show they typically are only able to achieve 100% of the RDA. While biological factors clearly contribute to poor dietary adherence, recent studies have documented behavioural and environmental barriers to adherence that includes parent-child interaction at mealtimes. While not ‘abnormal’, parent behaviours such as paying increased attention to the child in the form of coaxing, commanding and feeding when the child is engaged in behaviours incompatible with eating (food refusal, talking, leaving the meal) may serve to reinforce these child non-eating behaviours. Thus, dietary counselling alone, albeit necessary, is typically insufficient because of failure to specifically address these behavioural and environmental barriers to dietary treatment. Behavioural intervention that targets both nutrition education and behavioural management has been found to be effective in achieving an average increased energy intake of 4200 kJ (1000)kcal/d and weight gain of 1·48 kg over 9 weeks in children with CF. This intervention utilizes self-monitoring, goal setting and shaping to structure the delivery of treatment. It also teaches parents to utilize child behaviour-management techniques to motivate children to increase their energy intake. These behavioural strategies include differential attention (praising and ignoring), contingency management and behavioural contracting. The potential application of these techniques to dietary counselling is suggested.

Should food or supplements be used in the community for the treatment of disease-related malnutrition?

Strategies are needed for community-based treatment of disease-related malnutrition (DRM), which is a common debilitating condition that in the UK is estimated to cost >£7×109annually. Whilst dietary fortification and counselling are often used as a first-line treatment for malnutrition, the numbers of dietitians available to undertake and oversee such practices are currently insufficient to address the extent of DRM in primary care. Although dietary fortification and counselling can improve nutritional (primarily energy) intake, the evidence base for this practice is weak and it needs addressing with well-designed trials that assess clinically-relevant outcome measures and costs. Liquid oral nutritional supplements (ONS) are increasingly used in the community, often in combination with dietary counselling. The larger evidence base of trials that have assessed ONS suggests that nutritional intake and some functional outcomes can be improved in some patient groups in the community. Although meta-analysis indicates significant reductions in mortality (odds ratio 0.59 (95% CI 0.48, 0.72),n3258) and complication rates (odds ratio 0.41 (95% CI 0.31, 0.53),n1710) with ONSv. routine care, few of these studies are community based. Thus, the impact of ONS on clinical outcome, healthcare use and costs requires further assessment. Similarly, the clinical and cost efficacy of other strategies (e.g. sensory enhancement, music, behavioural therapy), alone or in combination with other treatments, requires greater investigation in order to meet the challenge of treating DRM more effectively and cheaply in the future.

Meal patterns, dietary fat intake and pancreatic enzyme use in preadolescent children with cystic fibrosis

OBJECTIVES

To describe the usual pattern of intake and adherence to cystic fibrosis (CF) food and pancreatic enzyme replacement therapy (PERT) recommendations in preadolescent children with CF and pancreatic insufficiency (PI).

METHODS

Children, 8 to 11 years old, with CF and PI were assessed for PERT adherence ratio (number taken/number prescribed per day) and energy and fat intake for 7 days (weighed food records), adherence to PERT and dietary recommendations, pulmonary function, growth status and stool fat malabsorption. Using the PERT adherence ratio, children were divided into good (> or =80%), moderate (60% to 79%) and poor (<60%) adherence groups.

RESULTS

Of the 75 children (age, 9.3 +/- 1.0 years; forced expiratory volume in 1 s, 95 +/- 14% predicted), 61% consumed less than 120% of energy intake, and 72% consumed less than 40% of calories as fat recommended for CF. Using the PERT adherence ratio (mean +/- SD, 75 +/- 14%), 29%, 61% and 9% of children had good, moderate and poor adherence, respectively. Better adherence to PERT was significantly associated with missing fewer snacks, higher energy intake, greater fat content of snacks and poorer growth status. About 85% of the children were in the 500 to 4000 lipase unit (LU) of PERT (LU/g fat per day) and 500 to 2500 LU/kg per body weight per meal guidelines, whereas only 58% to 68% were within the guidelines for snacks. Eleven percent of children always took PERT at an inappropriate time after meals.

CONCLUSIONS

Most preadolescent children with CF and PI did not meet dietary recommendations. Future educational and behavioral interventions focused on increasing PERT adherence with snacks, fat content of meals and snacks, appropriate timing of enzymes and adjustment of PERT and meal fat content are suggested.

Case study: providing evidence-based behavioral and nutrition treatment to a toddler with cystic fibrosis and multiple food allergies via telehealth

Barriers to successful outcome for cystic fibrosis (CF) therapies can include distance from a CF care center, co-morbid conditions that require individualized alterations to the prescribed treatment, and patient-provider interactions, among others. We present the case of a 21-month-old female with CF for whom modifications of an efficacious behavioral and nutrition treatment were made due to food allergies and distance from the CF care center. She was classified as at-risk nutritionally. Following treatment a significant increase in energy intake (calories) was observed in addition to her meeting weight and height growth rates for a child of this age and gender who is growing normally at the 50th percentile.

Behavioral aspects of nutrition in children with cystic fibrosis

PURPOSE OF REVIEW

Nutritional status in cystic fibrosis is important to the health and long-term survival of patients; however, children with cystic fibrosis are not achieving the dietary recommendations or achieving normal growth. This paper reviews current knowledge about behavioral and environmental barriers to dietary adherence in this population.

RECENT FINDINGS

Children with cystic fibrosis do not have the same appreciation of the need to gain weight as their parents. Parents of children with cystic fibrosis describe meal times as 'battling' with the child. Direct observation studies of meal times demonstrate that school-aged children with cystic fibrosis do not differ from children without cystic fibrosis on the frequency of behaviors incompatible with eating, as was seen in younger age groups, but parents of school-aged children with cystic fibrosis continue to engage in ineffective management styles at a greater frequency than parents of children without cystic fibrosis. Assessment of family functioning during mealtime demonstrates that these interaction patterns have a negative effect on family functioning in families of children with cystic fibrosis compared with families of same-age peers in all age groups: infancy/toddler, preschool, and school age.

SUMMARY

Achieving the cystic fibrosis dietary recommendations is challenging, and typical parenting strategies to encourage eating not only are ineffective but may have a negative impact on family functioning. To improve dietary adherence and decrease conflict at meals, children with cystic fibrosis and their parents need to be taught more effective management strategies as part of dietary counseling.

Randomized clinical trial of behavioral and nutrition treatment to improve energy intake and growth in toddlers and preschoolers with cystic fibrosis

OBJECTIVE

To conduct a randomized clinical trial comparing a behavioral and nutrition intervention (BEH) with a usual care control condition (CTL) for children (ages 18 months to 4 years) with cystic fibrosis (CF) and pancreatic insufficiency. This trial was designed to (1) evaluate a randomized comparison of BEH with CTL over 8 weeks, (2) provide a replication of the impact of BEH by inviting the CTL group to receive BEH after 8 weeks, and (3) examine the maintenance of BEH at 3- and 12-month follow-up.

METHODS

Of 14 eligible children, 10 were randomly assigned and initiated treatment (71% recruitment rate). Four participants were randomly assigned to BEH, and 6 were assigned to CTL (5 of whom chose to crossover to BEH). BEH included nutrition counseling to increase energy intake (via types of foods and addables/spreadables) and child behavioral management training to teach parents differential attention and contingency management skills. CTL was consistent with the 2002 CF Foundation Consensus Conference Guidelines for nutritional care.

RESULTS

BEH led to greater increases in energy intake pre- to posttreatment than CTL as measured by calories per day (842 kcal/day vs -131 kcal/day change). On receiving BEH, the change in energy intake was replicated with the CTL group (892 kcal/day change). At 3- and 12-month follow-up, energy intake was maintained (672 kcal/day increase from baseline and 750 kcal/day increase from baseline, respectively). Children in this study met or exceeded normal weight and height velocities from pretreatment to the 3-month follow-up (mean weight: 1.4 kg/6 months; mean height: 5.1 cm/6 months) and from posttreatment to the 12-month follow-up (mean weight: 2.5 kg/12 months; mean height: 8.3 cm/12 months).

CONCLUSIONS

Toddlers and preschoolers who have CF and received BEH were able to meet the energy intake recommendations for this disease and maintain these gains up to 12 months after treatment. In addition, these children demonstrated weight and height velocities from pretreatment to 12-month follow-up, consistent with the goal of normal growth. BEH is a promising, evidence-based, early nutritional intervention for children with CF. An upcoming multisite clinical trial will test BEH versus an attention control condition using a larger sample (N = 100), providing additional evidence about the efficacy of this treatment for energy intake and growth in young children with CF.

Scholarly Literature Review: Efficacy of Psychological Interventions for Pediatric Chronic Illnesses

OBJECTIVE

To review empirical studies of the efficacy of psychological interventions as adjuvant therapies for children with pediatric diabetes, cancer, cystic fibrosis, and sickle cell disease.

METHODS

A search was conducted for qualifying studies published since 1980. Only studies meeting basic criteria for external and internal validity were included. Nineteen studies were identified, providing data on 62 outcome variables. Effect sizes (ESs) were analyzed by illness type, intervention type, and strength of internal and external validity of the research design.

RESULTS

Overall, interventions were associated with large ESs, which were not significantly moderated by illness type or intervention type. However, larger ESs were associated with lower scores on validity of research design.

CONCLUSIONS

Adjuvant psychological interventions for pediatric chronic illnesses appear in general to be efficacious, associated with a large mean ES across a range of outcome variables. However, until more studies have been completed using stronger research designs, only tentative conclusions can be drawn.

Child behavior and parent management strategies at mealtimes in families with a school-age child with cystic fibrosis

Parent and child mealtime behaviors in school-age children with cystic fibrosis (CF; n = 28) and children without CF (n = 28) were examined during dinner meals by using multivariate analysis of variance. Parents of children with CF were found to differ from comparison parents in the frequency and rate of child management strategies. No differences were found in child behaviors. As the meal progressed, children displayed an increase in behaviors incompatible with eating, and parents increased behaviors to encourage eating. Slow eaters (> 20 min) with CF consumed more calories at the dinner meal than fast eaters (< 20 min) but did not achieve a higher daily caloric intake. Interventions targeting improvement of parent- child interactions during the mealtime are needed to achieve optimal dietary intake.

Weight and energy: parents' and children's perspectives on managing cystic fibrosis diet

AIMS

To explore the meanings that parents and children attach to food and eating, and how these influence their approaches to dietary management of cystic fibrosis (CF).

METHODS

Ethnographic design using in-depth interviews with 32 children with CF (aged 6-14 years) and their parents, and participant observations during visits to CF clinics with a sub-group of 21 children. Data were analysed using the constant comparative method and theoretical sampling was used to further explore and develop emergent themes.

RESULTS

Dietary management was found to be a demanding task for children and their parents, and priorities differed between them. A priority of feeding for parents was to protect their children's long term physical health and survival by keeping their weight up. A challenge for parents was to ensure their children's cooperation with eating. A priority for children in being healthy was to have energy for physical activities and so energy rather than weight was of immediate relevance to their daily lives. These differences between parents and children gave rise to tensions and conflicts in their interactions with one another in managing diet.

CONCLUSIONS

Healthcare professionals should take account of the meanings that children and their parents attach to food and eating that can influence their decisions about implementing CF dietary recommendations. The role of children in making food choices has implications for acknowledging them as active participants in their dietary care and for adopting child centred approaches to dietary advice for CF.

Mealtime interactions in families of pre-schoolers with type 1 diabetes

OBJECTIVES

Parents of pre-schoolers with type 1 diabetes report more behavioral feeding problems and concerns about the management of mealtime behavior than parents of age-matched healthy control children. We compared mealtime interactions of 26 families of pre-schoolers with type 1 diabetes (13 boys; mean age = 4.4 yr) and those of 26 families of age-matched control children by using direct observation of meals.

METHODS

Families had three meals videotaped in their home. Trained coders independently scored each meal for parent, child, and child eating behaviors by using the Dyadic Interaction Nomenclature for Eating (DINE).

RESULTS

The frequency of parent and child behaviors at mealtimes (such as instructions to eat, coaxing, feeding, refusing food, leaving the table, and non-compliance with instructions to eat) was similar for both groups. Children ate less and engaged in more behaviors incompatible with eating during the second half of meals than during the first half. Children, who took over 19 min to eat at meals (average duration for controls) played more and ate less than children, who ate more quickly.

CONCLUSIONS

Despite increased parental concern, pre-schoolers with type 1 diabetes do not have more challenging mealtime behaviors than age-matched healthy controls. Interventions to inform parents of pre-schoolers with type 1 diabetes about typical child mealtime behaviors and teach effective strategies for managing problematic behaviors are needed to reduce parental concerns and may be critical for improving adherence to diet if a relation between child behavior, adherence, and metabolic control is demonstrated. Further research is required to investigate whether these mealtime interactions adversely impact dietary adherence and blood glucose excursion.

Family functioning in young children with cystic fibrosis: observations of interactions at mealtime

This study examined family functioning at mealtime, a context relevant to the management of cystic fibrosis (CF). Thirty-three families of children with CF and a control sample of 33 families of children without a chronic illness were assessed. Family functioning was rated during a videotaped dinner using the McMaster Mealtime Interaction Coding System (MICS), and mealtime behavioral problems were assessed using the Behavioral Pediatrics Feeding Assessment Scale (BPFAS). Ratings for families of children with CF were lower than for control families on overall functioning and five of six MICS dimensions (Communication, Interpersonal Involvement, Behavior Control, Affect Management, Roles). In families of children with CF, better family functioning was related to less frequently occurring mealtime behavioral problems (BPFAS); however, family functioning was not related to the child's weight status or the child's caloric intake. Data support that nutritional intervention may be maximized if dietary adherence is promoted in the context of positive parent-child and family interactions.

Increasing adherence to cystic fibrosis treatment: a systematic review of behavioral techniques

Cystic fibrosis is a fatal chronic illness that primarily affects the respiratory and pancreatic systems. Treatment includes daily medications, enzyme and vitamin supplements, a high-calorie diet, and airway clearance sessions (e.g., chest physiotherapy, exercise). Although this regimen is essential to longevity, families have difficulty adhering to the multiple treatment components. Adherence is especially problematic with diet, chest physiotherapy, and exercise. Studies utilizing behavioral techniques to increase adherence to cystic fibrosis treatment components have been conducted with varying results. In this paper, a critical review of these treatment studies and suggestions for future work are presented.
