Building better bones in childhood: a randomized controlled study to test the efficacy of a dietary intervention program to increase calcium intake.

BACKGROUND/OBJECTIVES: Many children do not consume the recommended daily allowance of calcium. Inadequate calcium intake in childhood may limit bone accrual. The objective of this study was to determine if a behavioral modification and nutritional education (BM-NE) intervention improved dietary calcium intake and bone accrual in children. SUBJECTS/METHODS: 139 (86 female) healthy children, 7-10 years of age, were enrolled in this randomized controlled trial conducted over 36 months. Participants randomized to the BM-NE intervention attended five sessions over a 6-week period designed to increase calcium intake to 1500 mg/day. Participants randomized to the usual care (UC) group received a single nutritional counseling session. The Calcium Counts Food Frequency Questionnaire was used to assess calcium intake; dual energy X-ray absorptiometry was used to assess areal bone mineral density (aBMD) and bone mineral content (BMC). Longitudinal mixed effects models were used to assess for an effect of the intervention on calcium intake, BMC and aBMD. RESULTS: BM-NE participants had greater increases in calcium intake that persisted for 12 months following the intervention compared with UC. The intervention had no effect on BMC or aBMD accrual. Secondary analyses found a negative association between calcium intake and adiposity such that greater calcium intake was associated with lesser gains in body mass index and fat mass index. CONCLUSIONS: A family-centered BM-NE intervention program in healthy children was successful in increasing calcium intake for up to 12 months but had no effect on bone accrual. A beneficial relationship between calcium intake and adiposity was observed and warrants future study.

Observational assessment of family functioning at mealtime in preschool children with cystic fibrosis.

OBJECTIVE: To examine functioning during a dinner meal in families of a child with a chronic illness that requires dietary treatment recommendations, as compared to families of a child without a chronic illness. METHODS: Ratings of seven dimensions of family functioning on the McMaster Mealtime Family Interaction Coding System (MICS) were obtained on 29 families of children with CF and 29 families of children with no chronic illness, ages 2 to 6 years, during a videotaped dinner meal at home. RESULTS: Ratings of families with a child with CF were significantly lower than those for families of children without a chronic illness on Overall Family Functioning and five of the six MICS dimensions: Communication, Interpersonal Involvement, Affect Management, Behavior Control, and Role Allocation and approached significance on the Task Accomplishment dimension. The ratings of families of a child with CF were in the "clinically significant" range on all subcales, including Task ACCOMPLISHMENT. CONCLUSIONS: This study suggests that family functioning at mealtimes may be different in families of children with CF in which explicit dietary guidelines exist than in families of children with no illness or dietary guidelines. These results are discussed in terms of global family functioning and treatment approaches to dietary treatment recommendations.

Dietary recommendations to prevent and manage chronic pediatric health conditions: adherence, intervention, and future directions.

This review provides a summary of the dietary aspects of pediatric health conditions. Within each condition, dietary recommendations are reviewed, and adherence rates, factors affecting adherence, and known interventions are reported. Findings indicate that knowledge is necessary but not sufficient for dietary change. Interventions specifically targeting diet appear more promising than interventions aimed at global treatment adherence. Behavioral interventions and group treatment modalities also appear promising. Recommendations for future research include a systematic assessment of barriers to dietary adherence across populations, integration of the research on normative development of eating behavior in childhood, and the application of this information to the design and implementation of future treatment.

Parent and child mealtime behavior in families of children with cystic fibrosis.

OBJECTIVES: We investigated the hypothesis that children with cystic fibrosis (CF) and their parents would show more maladaptive behaviors during dinner than children without CF and their parents. STUDY DESIGN: Children with CF (n = 32) and their parents were compared with 29 children without CF and their parents on the rate and frequency of parent-child behaviors during a typical dinner in the families' homes by using multivariate analyses of variance. RESULTS: When the rate of behavior, controlling for meal length, was examined, no differences were found between groups. However, parents of children with CF were found to differ from parents of control subjects in the frequency of direct and indirect commands (P <.05), coaxes (P <.01), physical prompts (P <.01), and feeding their child (P <.05). Children with CF were found to engage in more talk, spend more time away from the table, refuse food, and exhibit more noncompliance toward commands to eat than control children (P <.05 for all child variables). When behaviors were examined as a function of meal phase, parents of children with and without CF both showed an increase in commands (P <.01), coaxes (P <.05), feeds (P <.01), and physical prompts (P <.01) in the second half of the meal as compared with the first. Children with CF and the control children showed an increase in behaviors incompatible with eating during the second half of the meal compared with the first (P <.01). When faster eaters were compared with slower eaters, faster eaters consumed a higher percentage of the recommended daily allowance of energy (P <.01) than slower eaters and showed a trend to be at higher weight percentiles for age and sex (P =.08) regardless of group (CF or control). CONCLUSIONS: Children with CF and their parents do not differ from children without CF and their parents in the rate of behaviors exhibited or types of strategies used to encourage eating. However, children with CF and their parents engage in these behaviors more frequently. Our data do not support typical parenting behaviors as effective in meeting the CF dietary requirements. Additional support in the form of child behavior management training may be needed to assist parents in meeting their child's caloric requirements.

Nutrition intervention for weight gain in cystic fibrosis: a meta analysis.

OBJECTIVES: A meta analysis of the literature on treatment approaches to malnutrition in cystic fibrosis (CF) was conducted to evaluate the effectiveness of oral supplementation, enteral nutrition, parenteral nutrition, and behavioral intervention on weight gain before and after treatment. STUDY DESIGN: Eighteen studies were reviewed: four behavioral, six supplement, five enteral nutrition, and three parenteral nutrition. RESULTS: The weighted effect size for weight gain was large for each intervention: 1.51 behavioral, 1.62 oral, 1.78 enteral, and 2.20 parenteral intervention. All interventions produced a large effect for weight gain in patients with CF. A univariate analysis of variance indicated no significant difference among the four interventions, F(3, 17) = 0.87, p > 0.05. Effect size for calorie intake was also evaluated when data were available (N = 7 studies), yielding a sample size of three behavioral, two enteral, and two oral supplement studies. Analysis of variance indicated a significant effect for treatment, F(2,4) = 13.34, p < 0.05, with post hoc analysis indicating that the behavioral intervention had a greater effect size for calorie intake than oral supplement. CONCLUSIONS: All interventions were effective in producing weight gain in patients with CF. Behavioral intervention appeared to be as effective in improving weight gain in patients with CF as more invasive medical procedures. These findings support continued research on nutrition intervention with patients with CF including controlled clinical trials of the interventions and long-term follow-up on the impact of nutrition on disease progression.

Descriptive analysis of eating behavior in school-age children with cystic fibrosis and healthy control children.

STUDY OBJECTIVE: To investigate calorie intake, behavioral eating styles, and parent perception of eating behavior of school-age children with cystic fibrosis (CF) compared with healthy peers. DESIGN: A two-group comparison study. SETTING: A clinical sample of 28 school-age children with CF and a community sample of 28 healthy peers matched for age (6 to 12 years) and socioeconomic status. MEASUREMENTS AND MAIN RESULTS: The children with CF consumed more calories per day (2175 cal/d) than the control children (1875 cal/d) and achieved a significantly higher recommended daily allowance (RDA) of energy (128% of the RDA) than the control children (91.61% of the RDA). Fifty-four percent of the CF sample were achieving the CF dietary recommendations of 120% of the RDA. Despite this energy intake, the CF sample was significantly below the control sample on weight (24.56 vs 31.23 kg), height (125.48 vs 133.06 cm), and z score for weight (-0.811 vs 0.528) and height (-0.797 vs 0.371). On measures of behavioral eating style, the CF sample had significantly longer meals (23.90 min) than the control sample (17.34 min) and had a significantly slower pace of eating (43.27% 10-second intervals with bites) than the control sample (51.29% 10-second intervals with bites) but did not differ significantly on the number of calories consumed during dinner. On a measure of parent report of mealtime behaviors, parents of the children with CF rated mealtime behavior problems of "dawdles" and "refuses food" as more intense (mean, 3. 46) than did the parents of control children (mean, 2.67). For the CF sample, a significant correlation was found between the parent intensity ratings of problem behavior in general and meal duration (r = .48), and a significant negative correlation was found between the parent intensity ratings of problem mealtime behaviors and the percentage of intervals with bites (pace of meal) (r = -.533). CONCLUSIONS: Although the school-age children with CF were consuming more calories per day than their healthy peers, and more than 50% of the children in the CF sample were at or above the CF dietary recommendations, the children in the CF sample were significantly below the control children on measures of weight and height. The behavioral data suggest that increased caloric intake is not without cost, because the CF sample spent an additional 7 minutes per day at dinner and ate their meals at a slower pace than their healthy peers. These data were associated with higher intensity ratings of mealtime behaviors by parents of children with CF. These findings point to the need for individualized assessment of energy needs for school-age children with CF and comprehensive programs that teach parents behavioral strategies to motivate their children to meet these higher energy requirements in an adaptive manner.

Evaluation of a standard protocol for retentive encopresis: a replication.

Replicated the efficacy of a short-term, combined medical and behavioral intervention protocol for retentive encopresis. Fifty-nine children who had failed standard medical management for retentive encopresis and their parents participated in six 1-hour group treatment sessions. Treatment protocol combined the medical management strategies of enema clean out, increasing dietary fiber, and daily toilet sitting with the child behavior management strategies of differential attention, contingency management, and contracting. For the overall sample, the number of soiling incidents decreased 85%, the weekly frequency of independent bowel movements increased 15%, the weekly frequency of parent-prompted bowel movements increased 9%, and daily dietary fiber intake increased 121% pre- to posttreatment. The majority of the sample (86%) stopped soiling by the end of treatment and did not require further treatment. Results are discussed in terms of the comparability with previous findings and the utility of combined medical and psychological treatments for children with encopresis who have failed standard medical approaches.

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

Changes in calorie intake and weight gain were evaluated in five children with cystic fibrosis (CF) who received behavioral intervention and four children with CF who served as wait list controls. The behavioral intervention was a 6-week group treatment that provided nutritional education plus management strategies aimed at mealtime behaviors that parents find most problematic. The control group was identified prospectively and was evaluated on all dependent measures at the same points in time pre- and posttreatment as the intervention group. Difference scores on calorie intake and weight gain from pre- to posttreatment were compared between groups using t tests for independent samples. The behavioral intervention group increased their calorie intake by 1,032 calories per day, while the control group's intake increased only 244 calories per day from pre- to posttreatment [t(6) = 2.826, p = 0.03]. The intervention group also gained significantly more weight (1.7 kg) than the control group (0 kg) over the 6 weeks of treatment [t(7) = 2.588, p = 0.03] and demonstrated catchup growth for weight, as indicated by improved weight Z scores (-1.18 to -0.738). The control group showed a decline in weight Z scores over this same time period (-1.715 to -1.76). One month posttreatment, the intervention was replicated with two of the four children from the control group. Improved calorie intake and weight gain pre- to posttreatment were again found in these children. At 3- and 6-month follow-up study of children receiving intervention, maintenance of calorie intake and weight gain was confirmed. No changes were found on pulmonary functioning, resting energy expenditure, or activity level pre- to posttreatment. This form of early intervention appears to be promising in improving nutritional status and needs to be investigated over a longer period of time to evaluate the effects of treatment gains on the disease process.

Coping with everyday and disease-related stressors by chronically ill children and adolescents.

OBJECTIVE: This study examines those aspects of disease that chronically ill children find stressful and the coping strategies they report using to manage these stressors. In particular, we examined whether a state or trait conceptualization of coping was most applicable to this population. METHOD: A total of 177 children with varying chronic illnesses were asked to complete a coping checklist in response to a self-generated illness-related problem and an everyday problem. RESULTS: Analyses of coping strategy stability revealed gender but not age effects. Some coping strategies were used equally across varying illness-related stressors, but others, e.g. distraction, blaming others, and emotional regulation, varied by type of stressor. Moderately consistent patterns were found across illness-related and non-illness-related situations for the same individual. CONCLUSIONS: The results suggest that coping strategies used by chronically ill children have some stability but do vary across situations. Clinicians might benefit from routine screening of coping in chronically ill children.

Eating in preschool children with cystic fibrosis and healthy peers: behavioral analysis.

STUDY OBJECTIVE: To investigate calorie intake, behavioral eating styles, and parent perception of eating behavior of preschool children with cystic fibrosis (CF) compared with healthy peers. DESIGN: A two group comparison study. SETTING: A clinical sample of 32 preschool children with CF (aged 2 to 5 years) and a community sample of 29 healthy peers matched for age and socioeconomic status. MEASUREMENTS AND MAIN RESULTS: The two groups did not differ on the total number of calories consumed per day or the percentage of calories derived form fat. The CF sample achieved a significantly higher percent of the recommended daily allowance (RDA) of energy (95% RDA) than the control group (84% RDA), P < .05, but did not achieve the CF dietary recommendations of 120% RDA. On measures of behavioral eating style, the CF sample had significantly longer meals (24.63 min) than the control group (18.57 min), P < .01, but did not differ on pace of eating or calories consumed per bite. On a measure of parent report of mealtime behavior, parents of the CF sample identified mealtime behaviors of "dawdles" and "refuses food" as more problematic (M = .93) than parents of control children (M = .22), P < .05. CONCLUSIONS: While preschool children with CF consume as much or more than healthy peers, they are not achieving the CF dietary recommendations. Furthermore, there appear to be behavioral differences in eating and parent perception of CF children's eating that may contribute to the failure to achieve dietary recommendations.

Modifying problematic mealtime interactions of children with cystic fibrosis and their parents via behavioral parent training.

Implemented behavioral parent training targeting maladaptive mealtime behavior with two children with cystic fibrosis (CF) and their parents. Treatment was implemented in multiple baseline fashion across the two families. Primary dependent measure was coding of parent and child behaviors from videotaped dinners. Data were also collected on the children's daily calorie intake and weight. During treatment and at the posttreatment follow-ups, parents' attention to disruptive behavior decreased, attention to appropriate eating increased, and parental control at meals increased. The children showed an increase in appropriate behavior and a decrease in disruptive behavior; caloric intake and weight also improved. Results are discussed in terms of the applicability of behavioral intervention with feeding problems in children with CF.

Increasing calorie consumption in children with cystic fibrosis: replication with 2-year follow-up.

Three mildly malnourished children with cystic fibrosis and their parents participated in a behavioral group-treatment program that focused on promoting and maintaining increased calorie consumption. Treatment included nutritional education, gradually increasing calorie goals, contingency management, and relaxation training, and was evaluated in a multiple baseline design across four meals. Children's calorie intake increased across meals, and total calorie intake was 32% to 60% above baseline at posttreatment. Increased calorie consumption was maintained at the 96-week follow-up (2 years posttreatment). The children's growth rates in weight and height were greater during the 2 years following treatment than the year prior to treatment. Increases in pace of eating and calories consumed per minute were also observed 1 year posttreatment. These findings replicated and extended earlier research supporting the efficacy of behavioral intervention in the treatment of malnutrition in children with cystic fibrosis.

Common problems and coping strategies reported in childhood and early adolescence.

This research investigated problems commonly experienced by children and young adolescents, and the strategies they use to cope with these events. Six hundred seventy-six children, ages 9-13 years, were asked to identify a problem they recently experienced and to describe the strategies they used to cope with it. In addition, they were also asked to complete a scale describing how they coped with a common problem (being grounded by parents). In general, we found that children reported four common Stressors: parents, siblings, school, and friends. These Stressors were the same across age and sex; however, the coping strategies employed differed by age and type of problem. Both age and sex effects were found in reported use of coping strategies to deal with being grounded by parents. The results of this study suggest that more research must be performed to offset the lack of data in the area of children's normative coping. The implications of the findings for clinical assessment and treatment of children are discussed.

Group behavioral treatment of retentive encopresis.

Investigated the efficacy of behavioral group treatment for children with retentive encopresis who had previously failed medical management. Eighteen children between the ages of 4 and 11 years and their parents were seen in small treatment groups of 3 to 5 families over 6 sessions. The sessions focused on education about retentive encopresis, and the integration of behavioral parenting procedures with medical management. Parents and children were taught to deliver an enema clean-out, increase the children's dietary fiber, and appropriate toileting techniques. The results indicated that children significantly increased their fiber consumption by 40%, increased appropriate toileting by 116%, and decreased their soiling accidents by 83% pre- to posttreatment. Further, these treatment gains maintained or improved at the 6-month follow-up. The results are discussed in terms of cost-effective interventions and the interface between psychology and medicine in pediatric psychology.

A behavioral approach to increasing calorie consumption in children with cystic fibrosis.

To increase calorie consumption of 5 mildly malnourished children with cystic fibrosis (CF), intervention was implemented in multiple baseline fashion across snack and three meals. Intervention involved nutritional education establishing gradually increasing calories goals, teaching parents contingency management strategies, and a reward system for achieving calorie goals. Following 6 treatment sessions, the children's calorie intake increased across meals and total calorie intake was 25 to 43% above baseline. The calorie increase was maintained at 9-month follow-up. Significant changes in weight and height were made during treatment and the year following intervention. The results suggest that the long-term oral intake of children with CF can be modified by a short-term behavioral intervention.

Social adjustment of children successfully treated for cancer.

Compared 56 children between the ages of 5 and 12 years to a sample of healthy controls. All cancer patients had been treated between the ages of 2 and 5 years. Children completed the Self-Perception Profile for children and questionnaires assessing social adjustment. Parent and teacher ratings were also obtained. The cancer patients reported greater feelings of isolation than the controls but otherwise few differences were noted. There were few differences between cancer patients and controls in the teacher and parent report. Results are discussed in terms of the need to investigate behavioral sequelae of childhood illness and directions for future research.

Encopresis: behavioral parameters associated with children who fail medical management.

The present study examined behavioral parameters such as parent management of encopresis and parental coping styles (active, cognitive, and avoidance) as predictors of success with medical management of encopresis. The results suggest that parents use a variety of management strategies and treatment success cannot be predicted using these variables. However, in line with previous research the presence of child behavior problems appeared to be a potential predictor variable.

Common problems and coping strategies. I: Findings with normal adolescents.

This study investigated problems commonly experienced by adolescents and the strategies they use to cope with these events. Coping strategies were examined across the subjects' emotional state and their evaluation of the problem. In general, adolescents reported four common stressors that were similar across age groups and gender. However, males differed from females in the frequency of these problems. Further, while the stressors were similar, the frequency with which the coping strategies were employed and the efficacy ascribed to them differed across sex and across problem type. These findings are discussed in terms of the stress and coping literature with adults and the implications for clinical assessment and treatment of adolescents.
