Objective: To evaluate the effectiveness of the educational program aimed at preventing obesity among school adolescents, anchored in the trans-theoretical model of behavior change. Method: a quasi-experimental study of a single group, with a quantitative approach, carried out in a public high school in the city of Sobral-Ceará with 39 adolescents through the implementation of an educational program. Results: the educational program was effective in reducing anthropometric variables: weight (58.85 to 58.31, p=0.005); abdominal circumference (73.5 to 72.65 cm, p=0.000); hip circumference (91.65 to 90.75 cm, p=0.000) and body mass index (22.89 to 22.67 kg/m2, p=0.012). In M-1, most students were in the pre-contemplation stage (66.7%). Along the moments of collection, it was observed a discrete increase in the percentage of contemplation. Conclusion: educational interventions to prevent juvenile obesity are valid tools to be used by health professionals together with the school, favori...

BACKGROUND/OBJECTIVES: The objectives of this study were to evaluate nutritional status, aptitude and physical activity at the beginning and end of the nutrition education and physical activity intervention program as compared with a control group. METHODS: We conducted a 28-week quasi-experimental study involving 238 students (108 in the intervention group (IG) and 130 in the control group (CG)). The IG participated in curricular and extracurricular activities for nutrition education (50 min once a week) and physical activity (50 min twice a week), and the CG participated only in curricular activities. Nutritional status was determined using body mass index, according to the WHO 2007 curve. The effect of the intervention program was evaluated using a model of generalized estimating equations. RESULTS: Among overweight students, a greater reduction in percentile of BMI was observed in the IG (64.6%) compared with CG (36.4%), P ¼ 0.001. Improvement in nutritional status occurred in 26.2% of IG versus 10.4% of CG (P ¼ 0.014). The IG showed a significant increase in the amount of moderate or vigorous physical activity (P ¼ 0.012), whereas in the control group the increase was not significant (P ¼ 0.810). In three physical fitness tests, the IG showed significant improvements in performance (Po0.001), whereas the control group's performance was worse in the final evaluation. CONCLUSIONS: The intervention program had a positive effect on overweight, with significant improvements in nutritional status and physical fitness.
Physical activity in children and youth in Spain: future actions for obesity prevention
Nutrition Reviews, 2009
The aim of the study presented here was to determine the relationship between age and certain socioeconomic factors and the effect that physical activity may have on the prevalence of overweight and obesity among Spanish children and adolescents. The sample derived from the enKid study, a cross-sectional study of a representative sample of the Spanish population aged 2-24 years. Body mass index was calculated from measured weight and height. A physical activity questionnaire was administered. Age, socioeconomic level of the families, the mother's level of education, and the geographical area of residence were related to the prevalence of overweight and obesity among Spanish males.
Physical activity level in overweight adolescents at school: a systematic review
Revista Brasileira de Cineantropometria & Desempenho Humano, 2021
– The objective of this systematic review was to identify the association between overweight/obesity and level of physical activity in Brazilian children and adolescents in the school setting. For search strategy, the main reference databases (PubMed, LILACS, SciELO, SPORTDiscus, Web of Science, ERIC) were used. Baseline searches resulted in 3,265 potentially relevant titles (2,775 titles after removal of duplicate studies); 21 studies met all inclusion criteria and were included for analysis. Studies were carried out from 2007 to 2019; 47.6% of them were conducted in Southern Brazil, and only one study had nationwide approach. Prevalence from 5.4% to 21% was identified for overweight, 3.5% to 16.9% for obesity and 11.8% to 40.1% for overweight + obesity. According to results, 64.3% of overweight, 69.8% of obese and 37.7% of young overweight people were considered insufficiently active. The non-standardization of instruments to assess levels of physical activity and the lack of info...
Obesity Prevention for Junior High School Students: An Intervention Programme
Background: Generally, schools are an important setting to provide programmes for obesity prevention for children because the vast majority of children attend school. This study investigates how an intervention programme in the school subject of Physical Education can help reduce obesity for junior high school students in combination with information on dietary and health matters in school and family. Materials and Methods: A quantitative study for junior high school students (N = 250) and a questionnaire were used as research methods. Results: A large number of the participants was found to be overweight (24.4%) and the boys outnumbered the girls both in the group of overweight students and the group of obese students. Also, the parents’ obesity is an important factor to whether a child will become obese or overweight as the bodymetrics of the parents showed that obese parents tend to have obese children. Finally, physical activity (for an extra two hours per week) and the dietary ...
Effects of a strategy for the promotion of physical activity in students from Bogotá
Revista de saude publica, 2018
To examine the effect of the promotion of physical activity during recess on the levels of physical activity, sedentary behaviors, and adiposity of Colombian students. Three schools were randomly selected by an intervention group in Bogotá, Colombia, in 2013: Intervention (Active Module of Active Recess - MARA) + Text Messages (SMS) (MARA+SMS group), intervention (MARA group), control (control group). Intervention was implemented for ten weeks. The duration and intensity of physical activity and sedentary behaviors were measured objectively using accelerometers Actigraph-GT3X+. Adiposity was measured by body mass index and fat percentage. We measured at baseline (T0) and during the tenth week of intervention (T1). We evaluated the effect of the intervention using a difference-in-difference analysis (DID). We included 120 students (57.5% girls; mean age = 10.5 years; standard deviation [SD] = 0.64). There was a significant increase in the mean daily minutes of moderate to vigorous ph...
Objective: Lack of physical activity, unbalanced diet and unhealthy lifestyles have lead to lifelong obesity. Obesity in Pakistani children and adolescents has also becoming an important public health problem due to changes in life style and other factors. Our aim is to determine relationship between physical activity and obesity in urban youth. Methods: A Cross-sectional study was conducted from 01 June 2013 to 30 December 2013 in Hyderabad Pakistan. A total of 504 male and female students of class six to ten were selected through simple random sampling. They were interviewed by trained data collectors through obesity and physical activity questionnaire. Anthropometric measurements were done with calibrated instruments using the age and sex specific BMI cut off points according to WHO growth reference. Results: The prevalence of overweight (> 85th Percentile) and obesity (>95 th percentile) was 23% and 15% among the boys respectively whereas in girls the prevalence of overweight and obesity was 16% and 8% respectively. A significant proportion of girls (86%) and boys (85%) had abnormal waist to hip ratios. Mean of moderate physical activity 6.2 hours SD 5.9 and mean of hard physical activity 5.3 hours SD 5.2. Conclusion: Promoting physical activity has become a priority because of its role in preventing childhood obesity and chronic disease. The determinants of the obesity lie within the home and school environment and the overall socio-cultural phenomena. Children are spending an alarmingly large part of their daily time on sedentary activities and having minimal physical activity.
