Objective: Obesity prevalence among Chilean children is 19?4 %. The present study aimed to assess the effectiveness of a school-based obesity prevention programme. Design: Non-randomized controlled study. The intervention included activities in nutrition and physical activity, fully applied the first year and partially in the second one. Primary outcomes were BMI Z-score (BMIZ) and obesity prevalence; secondary outcomes were waist circumference and triceps skinfold thickness. Time effects were assessed by changes in BMI-related variables by gender and period (ANOVA and Tukey test), while intervention effects were determined by comparing changes in (i) obesity prevalence by gender and period (PROC GENMOD) and (ii) BMIZ according gender, age and period (PROC MIXED). Setting: Primary schools in the Chilean cities of Casablanca (intervention group) and Quillota (control group). Subjects: One thousand seven hundred and fifty-nine children from three schools (intervention group) and 671 from one school (control group). Results: Over the two years, obesity prevalence and BMIZ declined significantly in the intervention group; from 17?0 % to 12?3 % and 14?1 % to 10?3 % in boys and girls, respectively, and from 0?62 to 0?53 and 0?64 to 0?58, respectively. In the control group, obesity remained stable at about 21 % and 15 %, while BMIZ increased significantly in the second year. BMIZ declined in both genders and all age categories in the intervention group during the first year (significant only in younger boys). No changes occurred during the summer, while during the second year, BMIZ increased in boys and girls from both groups (significant only in the younger control boys). Obesity declined significantly only in boys during the first year. Conclusion: Effectiveness was greater in the first school year and more evident in younger boys. KeywordsPrevention School-based Childhood obesity ChileIn Chile, the prevalence of obesity has risen sharply since the early 1980s (1) and especially in young children, whose obesity rates have increased from 7?0 % in 1987 to 18?5 % in 2005 (2) . This can be attributed to multiple factors linked to the nutrition transition which affect both energy intake and physical activity (3,4) . During the 1980s and 1990s, income more than doubled and poverty dropped by 50 %. Mean energy intake increased, especially among the urban poor. On the energy output side, sedentarism linked to urbanization increased significantly; presently, 87 % of the population live in urban areas and about 90 % are classified as sedentary. The Ministry of Health acknowledged in 1997 the need to address obesity prevention by establishing a national health promotion programme (Vida Chile) with specific goals at each stage of the life course. For children, the goals are to reduce obesity at school entry (6 years of age), using WHO criteria (5) , from 16 % observed in the 2000 baseline to 12 % by the year 2010; and to reduce sedentary behaviour in those 15 years of age and older from 91 % to 84 % (6) .To achieve thes...

“…As reported by Baranowski et al, 31 if for example, teachers do not implement the experimental curricula with substantial fidelity, desired changes may have limited effect. Additionally, public school teachers in general have a very limited knowledge in nutrition, 6 and training time was very short.…”

“…(i) Educational program for children from fourth to eighth grades: We implemented a shorter version of a specially designed child-friendly classroom nutrition education program, which was recently developed by INTA and FAO 6 with the objective of introducing food and nutrition contents for the curricula of Latin American primary schools. The program was initiated with 4th grade students since the dietary assessment questionnaires to be completed by the children required them to be able to read and write.…”

OBJECTIVE:To assess the impact of a 6 months nutrition education and physical activity intervention on primary school children through changes in adiposity and physical fitness. DESIGN: Longitudinal school-based controlled evaluation study. SUBJECTS: Children from 1st to 8th grade, 2141 in intervention and 945 in control schools. INTERVENTION: Nutrition education for children and parents, 'healthier' kiosks, 90 min of additional physical activity (PA) weekly, behavioral PA program and active recess. MEASUREMENTS: Adiposity indices (BMI, BMI Z-score, triceps skinfold thickness (TSF), waist circumference and physical fitness (20 m shuttle run test and lower back flexibility). RESULTS: Positive effect on adiposity indices (except TSF) was observed in boys (Po0.001 for BMI Z), while both physical fitness parameters increased significantly in both boys (Po0.001 for each test) and girls (Po0.0001 for each test). A differential effect in BMI Z was observed according to baseline nutritional status. CONCLUSIONS: This intervention showed a robust effect on physical fitness in both genders and decreased adiposity only in boys.

“…The main barriers to implementing nutrition education programs for primary school children in developing countries are the teachers' lack of nutrition knowledge, inappropriate educational materials, and finally the difficulty in obtaining governmental support to address this issue with an adequate methodology (Olivares et al, 1998). Taking these barriers into consideration, the fact that 90% of the teachers are very interested in acquiring knowledge in nutrition (FAO/Ministry of Education/INTA, TCP/CHI/0065, 2003), the Ministry of Education, and the Institute of Nutrition and Food Technology (INTA) of the University of Chile requested Food and Agriculture Organization of the United Nations (FAO) to jointly design and implement a technical cooperation project to incorporate food and nutrition education into the curriculum of 3rd-8th grade.…”

Nutritional status, food consumption and physical activity among Chilean school children: a descriptive study

et al. 2004

View full text Add to dashboard Cite

Objective: To assess the nutritional status, food consumption and physical activity (PA) habits of Chilean school children, as a baseline for developing an educational intervention. Design: Cross-sectional study. Subjects: A total of 1701 children from 3rd to 7th grade in nine schools located in three geographical regions. Methods: We determined body mass index, food consumption (quantified FFQ which we categorised into five groups), PA in terms of TV viewing and frequency of after school PA. The data were analysed according to age, nutritional status and gender. A logistic regression analysis was performed using obesity as outcome. Results: Obesity was higher among boys; younger children presented higher prevalence in both genders. Daily intake of dairy products varied between 240 and 308 g, fruits/vegetables, between 197 and 271 g, energy-dense foods between 343 and 460 g. In all, 22.3 and 47% of the children watched over 3 h of TV during the week and weekend, respectively. Older children watched significantly more TV during the week, while on weekends all children increased this time significantly. Boys were more active than girls after school. The logistic regression analysis showed a significant association between obesity and low intake of dairy products. Conclusions: Prevalence of obesity among Chilean children is high. Although TV time, intake of energy dense foods and fruits/ vegetables appeared as risk factors for obesity, only dairy consumption was significantly associated with obesity. Sponsorship: FAO
