Mothers' feeding behaviors in infancy: Do they predict child weight trajectories?

OBJECTIVE: To determine associations between mothers' feeding behaviors in infancy and children's weight from infancy through to toddlerhood in urban, low-income, minority families and to explore the contribution of concerns about infant eating/weight. METHODS: One hundred sixty-nine mother-infant dyads (88% African-American) were recruited from an inner city pediatric practice. Questionnaires measuring restrictive feeding, pressuring to eat, and concerns about infant overeating/weight and undereating/weight were administered, and infants weighed and measured, at 6-12 months. Anthropometric data up to 30 months were obtained from multiple (8.9 ± 2.6) well-child visits, with 84% completing 11 visits. RESULTS: Higher pressuring was associated with lower weight-for-length z-scores (WLZ) over the period from baseline out to 30 months and higher restriction with higher child WLZ over the same period. Pressuring and concern about infant undereating/weight were independently associated with WLZ, but the relationship between restrictive feeding and WLZ was reduced by accounting for concern about infant overeating/weight. Child weight trajectories were not influenced by feeding behavior. CONCLUSIONS: Mothers restricted heavier infants and pressured leaner infants to eat, and the relationship between restriction and higher infant weight was mediated by concern about infant overeating/weight. Correcting misperceptions and discussing feeding with mothers reporting concern may help prevent excessive early weight gain.

Effect of a brief intervention on evidence-based medicine skills of pediatric residents.

BACKGROUND: While Evidence-Based Medicine (EBM) skills are increasingly being taught in medical schools, teaching quality has been insufficient, so that incoming pediatric residents lack adequate EBM skills required for patient care. The objective of this study was to evaluate the effectiveness of a brief teaching module developed to improve EBM skills of pediatric residents. METHODS: With-in subjects study design with pre- and post-test evaluation was performed in a large urban pediatric residency training program in Brooklyn, New York. We included PGY-1s during intern orientation, while second and third year pediatric residents were selected based on schedule availability. Sixty-nine residents were enrolled into the study, 60 (87%) completed the training. An EBM training module consisting of three or four weekly two-hour seminars was conducted. The module was designed to teach core EBM skills including (1) formulating answerable clinical questions, (2) searching the evidence, (3) critical appraisal skills including validity and applicability, and (4) understanding levels of evidence and quantitative results for therapy articles. A portion of the Fresno test of competence in EBM was used to assess EBM skills. The test presented a clinical scenario that was followed by nine short answer questions. One to three questions were used to assess EBM skills for each of the four core skills. The kappa co-efficient for inter-rater reliability was 0.74 (95% CI: 0.56-0.92). RESULTS: Prior to the training module, the residents achieved a mean score of 17% correct overall. Post intervention, the mean score increased to 63% with improvement in each EBM category. A mean of 4.08 more questions (out of 9) were answered correctly after the training (95% CI of 3.44-4.72). CONCLUSION: A brief training module was effective in improving EBM skills of pediatric residents.

The Downstart Program: a hospital-based pediatric healthy lifestyle program for obese and morbidly obese minority youth.

Although obesity affects all cultures, ethnic groups and social strata, this disorder affects African Americans, Hispanics and the poor at a disproportionate rate. The Downstart Pediatric Healthy Lifestyle Program was developed to provide a multi-disciplinary behavioral modification program for inner city families in Brooklyn, New York interested in leading a healthier, more active lifestyle. The Downstart Program uses a four-pronged approach of medical evaluation, exercise, nutritional education and lifestyle modification. A psychological evaluation is performed to determine the individual's ability and readiness to participate in group activities. Baseline physical fitness, flexibility and muscle strength are measured, followed by a twice-weekly karate/martial arts/dance program, incorporating principles established by the President's Council on Exercise. Nutritional and behavioral modification aspects of the program consist of weekly education about food groups, portion control, goal setting and appropriate rewards for attaining goals. Our preliminary results indicate that the Downstart Program may be a viable intervention for weight loss. Further study is needed to improve strategies for motivating patients and means and criteria for assessing long-term effects on health and lifestyle.

Well-child care: effectiveness of current recommendations.

Well-child care is the main source of preventive health care for children in the United States. Repeated examinations of healthy children during health supervision visits are used to assess biomedical health, development, behavior, and family functioning. In addition, well-child care serves to provide parent education through age appropriate counseling referred to as anticipatory guidance. Recommendations for well-child care are found in the Health Supervision Guidelines III, published by American Academy of Pediatrics, last revised in 1993, and a publication from the National Center for Education in Maternal and Child Health, The Bright Futures, Guidelines for Health Supervision of Infants, Children and Adolescents, revised in 2000. This article reviews the evidence for the effectiveness of the current recommendation for well-child care including the recommendations for the number of visits, history and physical examination as a screening technique, observation of parent-child interaction, and the recommendation for provision of anticipatory guidance. This article also summarizes the recent advances in well-child care and identifies an agenda for future research.
