Participants in the exercise group reported more vigorous exercise (p < .001) and walking (p = .005) at post-test than controls. Aerobic dance and unsupervised activity resulted in a five-fold greater increase in relative VO2max compared with controls (p < .001). Although exercise and fitness decreased at follow-up, vigorous exercise (p = .001) and relative VO2max (p < .001) remained higher in the exercise group, suggesting maintenance at 1 year. CONDUSION:. Culturally tailored aerobic dance can increase vigorous physical activity, possibly generalizing to walking, and the combination can improve cardiorespiratory fitness in low-income, overweight, sedentary Latinas.

, and observations that their child has a poor appetite (32%) and would rather drink than eat (32%). Parents of children with CF chose a greater number of mealtime strategies and feelings as problems and reported more frequently using problematic strategies at mealtimes than did parents of controls. Examples of problematic strategies and feelings for parents of infants and toddlers with CF included feeling anxious/frustrated when feeding their children (37%), not feeling confident that their child eats enough (32%), and using coaxing to get their child to take a bite (26%). For the entire sample, a positive correlation of 0.29 was found between the number of mealtime behavior problems reported by parents and meal duration, suggesting the co-occurrence of problematic mealtime behavior with longer meal duration. No relationship was found between the number of child mealtime behavior problems reported by parents and the number of calories consumed during the filmed meal. For the CF sample, a correlation of ؊0.26 between children's weight percentile for age and the filmed meal duration was found, suggesting a tendency for meal duration to increase as children's weight for age decreases. Post-hoc analyses were conducted comparing infants and toddlers with previously reported samples of preschool and school-aged children on meal duration. Results demonstrated that in each group, children with CF had longer meals than age-matched controls.Conclusions. Our findings reveal significant deficits in achieving dietary recommendations for many families of infants and toddlers with CF. Only 11% of infants and toddlers with CF met the CF dietary recommendation of at least 120% of the RDA/day for energy. In addition, infants and toddlers were found to derive only 34% of their daily calories from fat, compared with the recommended 40% needed for a moderate to high fat diet.

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.

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.

Direct observation of mealtime behaviors indicates that parents of infants and toddlers with CF engage in more mealtime management behaviors than parents of controls and that young children exhibit more behaviors incompatible with eating as the meal progresses. These findings highlight modifiable targets for behavioral and nutrition interventions that can be specifically designed for families of infants and toddlers with CF.
