Relationship between dietary energy density and dietary quality in overweight young children: a cross-sectional analysis.

BACKGROUND: Observational research has found that lower energy density (ED) diets are related to reduced intake of fat and greater intake of fruits and vegetables. No study has examined the relationship between dietary ED and dietary quality, as determined by the Healthy Eating Index-2005 (HEI), in children who are overweight and obese. OBJECTIVE: Examine the relationship between dietary ED and HEI, determined from 3-d food records, in 156 children, aged 4-9 years, who had ≥85th percentile body mass index presenting for family-based obesity treatment. METHOD: Dietary ED, in kcal/g, was calculated using two methods: food and all beverages consumed (food+bev) and food only consumed (food). For calculation of HEI, all components of the HEI were included except oils. RESULTS: Participants were classified as consuming a low-ED, medium-ED or high-ED diet using tertile cut-off points with ED calculated using food and beverages(food+bev) or food only(food) . After controlling for group difference in child sex and race and parent sex, LOW(food+bev) and LOWfood had significantly (P < 0.05) higher total HEI scores, and total fruit, total vegetable and saturated fat HEI scores than HIGH(food+bev) and HIGHfood , with higher scores indicating greater quality. CONCLUSIONS: Lower dietary ED is associated with higher dietary quality in children presenting for obesity treatment. Additional research investigating an ED prescription on dietary quality in children who are overweight or obese is needed to better understand this relationship.

Alcohol craving predicts drinking during treatment: an analysis of three assessment instruments.

OBJECTIVE: The purpose of this investigation was to examine the utility of thee craving instruments to predict drinking during treatment. The three assessments used were the Penn Alcohol Craving Scale (PACS), the Alcohol Urge Questionnaire (AUQ) and Items 1-6 of the Obsessive subscale (OBS) of the Obsessive Compulsive Drinking Scale (OCDS). METHOD: The three instruments were administered during the course of a 9-month, double-blind, placebo-controlled trial of 100 mg/day of naltrexone, and a manual-based psychosocial intervention using the BRENDA manual conducted at the University of Pennsylvania's Treatment Research Center. Participants (133 men and 50 women at the initiation of the study) used these instruments to self-report craving on a weekly or biweekly basis. The weekly number of drinks was reported using the Timeline Followback interview. The data were analyzed with generalized estimating equations using craving scores at 1 week as the independent variable and number of drinks in the subsequent treatment week as the dependent variable. RESULTS: Each of the three scales predicted drinking during the subsequent treatment week. The PACS was the strongest predictor followed closely by the OBS and then the AUQ. Most important, craving as measured by the three scales was a stronger predictor of subsequent drinking than was drinking during the prior treatment week. CONCLUSIONS: Craving assessment provides a useful means of predicting drinking during treatment. Such information would be helpful in designing clinical trials and for many treatment modalities.

Carbamazepine treatment for cocaine dependence.

We report on a double-blind, placebo-controlled study of carbamazepine (CBZ) treatment for cocaine dependence. A previously reported uncontrolled study found CBZ to be a beneficial pharmacotherapy for cocaine dependence. Statistical analyses were performed on data from 82 subjects who were randomized to 10 weeks' treatment with either CBZ, titrated to 4-12 micrograms/ml, (n = 37) or placebo (n = 45). The two treatment groups did not differ for primary outcome measures of retention time in treatment, urine samples positive for cocaine metabolite, subject reported desire for cocaine or for subject reported side-effects. CBZ was not an effective treatment in this study.
