The Impact of a Short-term Intervention on Adolescent Eating Habits and Nutritional Knowledge.

BACKGROUND: Adequate dietary habits and physical activity during childhood and adolescence may promote growth and cognitive development and contribute to the prevention of chronic disease in later life. School is considered an important social environment that can promote healthy eating habits and life-style changes. OBJECTIVES: To evaluate the effects of a school-based intervention on nutritional knowledge, eating habits, and physical activity of adolescents. METHODS: We conducted a prospective questionnaire-based study. Anonymous questionnaires were administered at the beginning of the academic year (September 2014) in one high school. During the following year, vending machines containing milk products were installed within the school facility, and students were given two informative nutrition lectures regarding proper nutrition for age, calcium requirement and importance, and physical activity. One active sports day was initiated. At the beginning of the following academic year (September 2015), the students completed the same questionnaires. RESULTS: The study was comprised of 330 teenagers, mean age 15.1 ± 1.39 years, 53% males. Response rate was 83.6% ± 0.4% to multiple choice questions, 60.7% ± 0.5% to multiple section tables, and 80.3% ± 0.9% to open questions. Post-intervention, respondents reported an increase in eating breakfast (57% vs. 47.5%, P = 0.02) and a decrease in purchasing food at school (61.6% vs. 54.3%, P = 0.03). No changes were observed in consumption of milk products, knowledge regarding calcium and vegetable consumption, or sports activities. CONCLUSIONS: Short-term high school-based interventions may lead to improvements in eating habits but are not sufficient for changing nutritional knowledge and physical activity.

Monitoring Enables Progress: A Nationwide Quality Improvement Program in Children With Crohn Disease.

OBJECTIVES: In this quality improvement program, named quality in pediatric inflammatory bowel disease, we constructed a nation-wide platform that prospectively recorded clinically important quality indicators in pediatric inflammatory bowel diseases (PIBD), aiming at improving clinical management across the country. METHODS: Representatives of all 21 PIBD facilities in Israel formed a Delphi group to select quality indicators (process and outcomes), recorded prospectively over 2 years in children with Crohn's disease 2-18 years of age seen in the outpatient clinics. Monthly anonymized reports were distributed to all centers, allowing comparison and improvement. Trends were analyzed using the Mann-Kendall test, reporting τ (tau) values. RESULTS: The indicators of 3254 visits from 1709 patients were recorded from September 2017 to September 2019 (mean age 14.7 ±â€Š3.1 years, median disease duration 1.8 years (interquartile range 0.69-4.02)). An increase in three of five process indicators was demonstrated: obtaining drug levels of anti-tumor necrosis factor (TNF) (τ = 0.4; P = 0.005), utilization of fecal calprotectin (τ = 0.38; P = 0.008) and bone density testing (τ = 0.45; P = 0.002). Among outcome indicators, three of nine improved as measured during the preceding year: calprotectin <300 µg/mg (τ = 0.35; P = 0.015), and "resolution of inflammation" defined as a composite of endoscopy, imaging and fecal calprotectin (τ = 0.39; P = 0.007). Endoscopic healing reached borderline significance (τ = 0.28; P = 0.055). An increase in the use of biologics throughout the study was observed (τ = 0.47; P = 0.001) with a concurrent decrease in the use of immunomodulators (τ = -0.47; P = 0.001). CONCLUSIONS: Quality improvement nationwide programs can be implemented with limited resources while facilitating standardization of care, and may be associated with improvements in measured indicators.
