Social Inequalities in Breakfast Consumption among Adolescents in Spain: The DESKcohort Project.

Breakfast has a critical role in energy balance and dietary regulation. Consequently, it is considered an important component of a healthy diet, especially in adolescence, when there are great opportunities to consolidate habits and establish future patterns of healthiness in adulthood. Socioeconomic position (SEP) causes inequalities that are reflected in health behaviors, physical activity, mental health, and diet. Therefore, we conducted a cross-sectional study using data from the 2019-2020 DESKcohort project (Spain) to explore the relationships between breakfast and sociodemographic characteristics, health-related behaviors, and school performance of 7319 adolescents. Our findings showed that the prevalence of skipping breakfast every day was 19.4% in girls and 13.7% in boys and was related to students' SEP. The risk of skipping breakfast was 30% higher in girls from the most disadvantaged SEP, in comparison to those in the most advanced SEP (prevalence ratio (PR) = 1.30; 95% confidence interval (CI) = 1.11-1.54). Also, boys from the most disadvantaged SEP showed 28% higher risk of skipping breakfast than those in the most advanced SEP (PR = 1.28; 95% CI = 1.04-1.59). In conclusion, future public policies should be adapted considering a SEP and gender perspective to avoid increasing nutritional and health inequalities.

Medium-term evaluation of an educational intervention on dietary and physical exercise habits in schoolchildren: the Avall 2 study.

OBJECTIVE: To assess whether the benefits seen in nutrition, physical activity. and body mass index were maintained at 2 years of completion of the educational intervention. MATERIAL AND METHODS: An experimental, longitudinal, 4-year, two-arm, parallel study with cluster randomization to assess an intervention program aimed at children in their first year of primary schooling attending schools in the city of Granollers. Intervention consisted of promoting healthy dietary habits and increasing physical activity through the educational pedagogy Investigation, Vision, Action and Change (IVAC), applied over 2 school years (2006-2008). Weight and height of each child wee measured in situ, and families self-completed a physical activity survey and the Krece Plus quick test in 2006, 2008, and 2010. RESULTS: A greater increase in body mass index was seen in 2010 in children from the control group (2.84 ± 0.22 vs 1.96 ± 0.163 kg/m(2), <.001). Prevalence of overweight and obesity increased by 8% and 0.5% respectively in schoolchildren in the control group, while the intervention group showed a 5.3% increase in prevalence of overweight and a 3.6%decrease in prevalence of obesity. Prevalence of excess weight therefore increased by 8.5% in the control group and by 1.8% in the intervention group. Reduction in body mass indexincrease was maintained 2 years after completion of educational intervention regardless of sex, origin, maternal obesity, and educational level of parents. CONCLUSIONS: These results confirm that school-based interventions may help contain the current increase in childhood obesity.

Assessment of a school-based intervention in eating habits and physical activity in school children: the AVall study.

BACKGROUND: Obesity has become a global public health problem, which also affects children. It has been proposed that the educational interventions during childhood could be a key strategy in the prevention of obesity. OBJECTIVE: To evaluate the efficacy of an intervention on food habits and physical activity in school children. METHODS: A 2-year cluster-randomised prospective study with two parallel arms was used to evaluate an intervention programme in children in their first year of primary schooling (5-6 years of age) in schools in the city of Granollers. The intervention consisted of the promotion of healthy eating habits and physical activity by means of the educational methodology Investigation, Vision, Action and Change (IVAC). At the beginning and at the end of the study (2006 and 2008) the weight and height of each child was measured in situ, while the families were given a self-report physical activity questionnaire and the Krece Plus quick test. RESULTS: Two years after the beginning of the study, the body mass index of the children in the control group was 0.8 kg/m(2) higher than that of the intervention schools. The intervention reduced by 62% the prevalence of overweight children. Similarly, the proportion of children that ate a second piece of fruit and took part in an after-school physical activity increased in the intervention group. In the control group, the weekly consumption of fish was reduced. CONCLUSIONS: The educational intervention in healthy eating habits and physical activity in the school could contribute to lessen the current increase in child obesity.

Compliance with dietary guidelines in the Catalan population: basis for a nutrition policy at the regional level (the PAAS strategy).

OBJECTIVE: To analyse the degree of compliance with the nutrition objectives and population-based food guides and to indicate possible recommendations for their development within the framework of a Nutrition and Health Policy in Catalonia. DESIGN: Using data derived from the latest Catalan Nutrition Survey (ENCAT 2002-03) conducted by the Department of Health, compliance was analysed with respect to the recommendations derived as a result of a previously conducted Survey. In addition, compliance to the recommendations elaborated by the Spanish Society of Community Nutrition (SENC) was also evaluated. SETTING: Catalonian region located in the Northeast of Spain. SUBJECTS: Analysis is based on a total of 2160 individuals (996 males and 1164 females) aged 10-80 years interviewed in 2002-03. RESULTS: The analysis of compliance with the recommendations established in 1995 showed: (a) recommendation to maintain and increase consumption of fruits and vegetables was not achieved; (b) continued use of olive oil as the dietary fat of choice was met; (c) incomplete compliance with maintaining the Mediterranean diet traditions, especially in the younger cohorts; (d) compliance with the recommendation to decrease consumption of red meat and sausages, but non-compliance with guidance to maintain or increase fish consumption and (e) compliance with partially substituting whole milk and dairy for low-fat products. Compliance with the SENC Healthy Eating Guide revealed that those food groups with the worst results were meat and sausages (excessive), pulses (below recommendations) and fruits and vegetables (below recommendations). CONCLUSIONS: Compliance with dietary guidelines is low in Catalonia, and reflects the need for an effective nutrition policy in the region defined by the Autonomous Government as the Plan for the Promotion of Physical Activity and Healthy Eating (PAAS).
