Caloric requirement for refeeding inpatients with anorexia nervosa: the contribution of anxiety exercise, and cigarette smoking.

BACKGROUND: Refeeding inpatients with anorexia nervosa (AN) is costly, stressful, and can precipitate the refeeding syndrome. Caloric intake is usually increased gradually from a low starting point until a steady weight gain is achieved. There is no reliable equation that predicts the number of calories required for a weight gain. It was our clinical suspicion that anxiety, exercise, and cigarette smoking might increase the caloric need for refeeding. METHOD: We conducted an observational cohort study of 17 females with AN admitted to an inpatient eating disorder unit for refeeding. We estimated the energy intake by observation, the caloric expenditure due to exercise with a triaxial accelerometer, the number of cigarettes smoked by history, and the anxiety by the Beck Anxiety Inventory (BAI). RESULTS: Neither anxiety, exercise, or cigarette smoking predicted the caloric requirement for refeeding, individually or in combination. DISCUSSION: Our data suggest that the caloric requirement for weight gain during refeeding is not predicted by the patient's anxiety, exercise or smoking habits. The standard methods of estimating caloric requirements for refeeding remain indirect calorimetry and previous history.

Health status of preterm low-birth-weight infants. Comparison of maternal reports.

BACKGROUND: Developers of measures of child health status have documented acceptable reliability and some validity, but less attention has been paid to the concurrent and predictive validity of these measures. METHODS: We examined the concurrent and predictive validity of the RAND General Health Rating Index, the Stein-Jessop Functional Status II-R, and the mother's global assessment of her child's health on a 5-point scale, in a sample of preterm low-birth-weight children (n = 608) who were followed up as controls in the Infant Health and Development Program. We compared maternal-reported measures assessed at 24 months with other measures of growth, morbidity, functioning, and health care utilization assessed concurrently and at 36 months in bivariate and multivariate analyses. RESULTS: After controlling for other factors, the RAND General Health Rating Index and the Stein-Jessop Functional Status II-R were unrelated to the growth, utilization, or functioning measures. The RAND General Health Rating Index was significantly, but weakly, related to future morbidity. The mother's global perception of health was significantly related to outpatient utilization and behavior problems. CONCLUSIONS: Clinicians may find that maternal assessment of overall child health is a sensitive but nonspecific indicator of the mother's concern. For researchers, none of these measures seems likely to serve as a proxy for health care utilization or morbidity in studies of other phenomena, or as an indicator of detailed health outcomes.

Home environment and adaptive social behavior among premature, low birth weight children: alternative models of environmental action.

Used data from 465 premature, low birth weight children representing three major sociocultural groups (Caucasian, African American, Hispanic) to examine the relation between children's home environments and their adaptive social behavior. Results showed low to moderate associations between scores on the HOME Inventory at 1 and 3 years and scores on two measures of adaptive social behavior at 30 to 36 months, the Adaptive Social Behavior Inventory, and observations of mother-child interaction in a structured laboratory situation. Results indicated that responsive, nurturant care at both 1 and 3 years are related to child adaptive social behavior, as are cognitively stimulating experiences and materials. However, canonical correlational analysis indicated that only Acceptance and Variety of Experience, measured at age 3, and Variety of Experience measured at age 1 accounted for independent amounts of variance in adaptive social behavior as perceived by mothers. Also, only sociocultural group status and Learning Materials at 36 months contributed to the prediction of persistence and enthusiasm as observed in the laboratory setting.

A multifaceted intervention for infants with failure to thrive. A prospective study.

OBJECTIVE: To determine whether a multifaceted intervention decreased the incidence of failure to thrive (FTT) in a group of preterm infants with low birth weights and improved the 3-year intelligence, health, growth, and behavior status of the children with FTT. DESIGN: Three-year, prospective, randomized, clinical trial. SETTING: Eight large university hospital sites throughout the United States. SAMPLE: Nine hundred fourteen preterm infants with low birth weights who were born at the sites and met study criteria. INTERVENTION: Home visits weekly during the first year of life and biweekly thereafter until the age of 3 years to provide family support and implement two curricula; and attendance at a child development center from 12 months until 3 years of age, 5 days a week, to deliver an early childhood educational intervention. RESULTS: The incidence of FTT did not differ between the treatment and control groups (20% vs 22%). Overall, children with FTT in the treatment group were not different from children with FTT in the follow-up group on any of the outcome variables. However, after controlling for other factors, treatment group membership significantly contributed to the prediction model of 36-month IQ (P = .005) for the children with FTT. In addition, children with FTT in the intervention group with higher compliance demonstrated higher 3-year IQ and better behavior scores than the children with FTT in the low-compliance group. CONCLUSIONS: The intervention did not change the incidence of FTT or the 3-year outcomes in this low-birth-weight, preterm cohort. After controlling for multiple independent variables, marked effects on 3-year IQ were noted. In addition, these beneficial effects were most pronounced in families that were most complaint with the intervention.

A factor analytic study of the infant-toddler and early childhood versions of the HOME Inventory administered to white, black, and Hispanic american parents of children born preterm.

Factor analyses were performed on the Infant-Toddler and the Early Childhood versions of the HOME Inventory for 3 groups (blacks, whites, and Hispanics) of premature, low-birthweight children. Participants lived in 8 different U.S. cities. On the IT-HOME, 5 factors were originally retained for each group using the principal factors method of extraction. Factor structures for blacks and whites were similar, accounting for 85% and 75% of the variance, respectively. The structure for Hispanics was somewhat different; a 7-factor solution accounting for 65% of the variance was most interpretable. For the EC-HOME, 6 factors were retained for both black and white groups, accounting for 80% and 73% of the variance, respectively. For Hispanics, an 8-factor solution accounted for 59% of the variance. The factor structures for blacks and whites were largely in agreement with the current organization of items into subscales. The fit for Hispanics was not quite as good, but most factors also corresponded to current subscales.

Early indications of resilience and their relation to experiences in the home environments of low birthweight, premature children living in poverty.

The caregiving environment experienced by 243 premature, low birthweight (LBW) children living in poverty was examined to determine whether the quality of care such children receive affords them some measure of protection from the generally deleterious consequences of poverty and prematurity. Only 26 children were identified as functioning in the normal range for cognitive, social/adaptive, health, and growth parameters at age 3. These children, who showed early signs of resiliency, differed from nonresilient children in that they were receiving more responsive, accepting, stimulating, and organized care. They were also living in safer, less crowded homes. 6 "protective" aspects of caregiving were identified and used as part of a cumulative protection index. Children with less than 3 protective aspects of caregiving present at age 1 had only a 2% probability of being resilient, and only a 6% probability if fewer than 3 were present at age 3. Overall, premature LBW children born into conditions of poverty have a very poor prognosis of functioning within normal ranges across all the dimensions of health and development assessed. However, those raised in a setting with 3 or more protective factors were more likely to show early signs of resiliency.

Low-birth-weight infants born to adolescent mothers. Effects of coresidency with grandmother on child development.

OBJECTIVE: To explore the impact of young maternal age, coresidency with infant's grandmother, and other familial and environmental factors on development of low-birth-weight (LBW) infants. DESIGN: Prospective cohort analyses. SETTING: Eight medical institutions in different geographical locations participating in the Infant Health and Development Program. PARTICIPANTS: Control population of 272 LBW, preterm infants enrolled in the Infant Health and Development Program born to mothers aged 15 to 24 years. MAIN OUTCOME MEASURE: Child cognitive, behavioral, and health outcomes at 36 months' gestation-corrected age. RESULTS: Maternal age was not significantly related to child development. Coresidence with infant's grandmother was associated with improved cognitive and health outcomes. Maternal ethnicity, maternal verbal ability, and other environmental factors were also associated with child outcomes. CONCLUSIONS: Findings of this study support the need for programs that include the extended family of at-risk infants, providing education and literacy skills to the mothers and encouraging participation of all care givers of the child.

Risk factors and outcomes for failure to thrive in low birth weight preterm infants.

OBJECTIVE: To determine the epidemiology, clinical characteristics, and outcomes for low birth weight (LBW) infants with growth deficiency, or failure to thrive (FTT, the term commonly used by pediatric providers to describe growth deficiency or faltering in early childhood). DESIGN: Three-year prospective cohort study with matched case-control study of outcomes. SETTING: Eight large university hospital sites throughout the United States. SAMPLE: 914 LBW infants inborn at the sites and meeting study criteria. RESULTS: FTT was a common condition in this cohort, with 180 (19.7%) of 914 LBW infants meeting case criteria by 30 months. New cases of FTT peaked at 8 months gestation-corrected age. In addition to expected differences in growth between infants with and without FTT, infants with FTT had lower developmental indices and less stimulating home environments. At 36 months, FTT infants had lower IQ scores and were much smaller than infants without FTT. CONCLUSIONS: Growth deficiency, or FTT, is a common clinical condition for those involved in the follow-up care of LBW infants. Worse cognitive and growth outcomes were observed for those meeting the restrictive case criteria employed in this study. More than 80% of the cases in this LBW cohort did not involve any chronic medical disorders, but several biological and environmental differences were found between those who developed FTT and those who did not.

The HOME inventory: a new scale for families of pre- and early adolescent children with disabilities.

A preliminary form of a new version of the Home Observation for Measurement of the Environment (HOME) is presented. It is designed for use with families of children aged 10-15. The 80-item preliminary version of the Preadolescent HOME (PA-HOME) was field tested on 117 children with varying disabilities. The 80 items were selected from a pool of over 250 items by means of several field tests and accompanying item analyses. Both factor analyses and item analyses were used to help pare down items and produce a scale with acceptable psychometric properties. The psychometric properties of the PA-HOME are quite similar to those reported for the other three versions of the HOME Inventory. It appears to be a reasonably reliable scale with moderate correlations with other measures of the family environment, such as SES, social support, and marital stability. It has low to moderate correlations with measures of child competence in this sample of children with disabilities. The correlations are of the same general magnitude of correlations between the Infant-Toddler, Early Childhood, and Middle Childhood versions of HOME in samples of younger children with disabilities.

A reexamination of the association between HOME scores and income.

This study, which represents another look at the relationship between the HOME Inventory and income, uses data from the Infant Health and Development Program (IHDP), a multisite, longitudinal study of low-birth-weight preterm infants. Two versions of the HOME Inventory were used: The Infant/Toddler (IT-HOME), at 12 months of age, and the Early Childhood (EC-HOME), at 36 months of age. Predictor variables were income, ethnicity, maternal education, parity, gestational age, marital status, maternal age, and site. HOME scores were positively correlated with income. However, after controlling for the other variables in the models, the portion of the variance in HOME scores uniquely explained by income was quite low (IT-HOME, 5.1%; EC-HOME, 4.2%). Finally, the relationship between HOME scores and four child characteristics (cognitive development, growth, maladaptive behavior, and social competence) measured when the child was 36 months old were investigated using correlation. The results indicated that the quality of the home environment, as measured by the HOME Inventory, is related to children's development.
