Abstract

En 1.431 escolares de 4º básico (748 hombres y 683 mujeres) asistentes a escuelas de nivel socioeconómico (NSE) medio y bajo en Santiago, se evaluó el estado nutricional y el consumo de alimentos seleccionados como línea base de una intervención para promover el consumo de pescado. La prevalencia de obesidad alcanzó al 17 y 11,6% en los niños y niñas de NSE bajo y al 13,2 y 12,6% en el NSE medio, respectivamente (NS). El consumo de lácteos fue insuficiente, mayor en el NSE medio que en el bajo (356 vs 316 ml/promedio/día) (p<0.001). El consumo de frutas y verduras fue bajo en ambos grupos y el de pan mayor en el NSE bajo que en el medio (220 vs 203 g/promedio/día) (p<0.001). El consumo de pescado sólo alcanzó a los 9 g/promedio/día, sin diferencias por NSE. Los resultados del estudio muestran la necesidad de realizar intervenciones para aumentar el consumo de pescado en la población escolar

Translated abstract

Nutritional status and food intake of 1.431 school children of 4th grade (748 boys and 683 girls) were evaluated as a baseline of a project for promoting fish consumption The school children attended 20 schools of low and medium socioeconomic level (SEL) from Santiago. The resulting prevalence of obesity was 17 and 11.6% in boys and girls of low SEL, respectively, and 13.2 and 12.6%, in medium SEL (NS). The intake of dairy products was insufficient, higher in medium than in low SEL (356 vs 316 g/average/day) (p<0.001). Fruit and vegetable intake was low in both groups and bread intake higher in low than in medium SEL (220 vs 203 g/average/day) (p<0.001). The quantity of fish consumed was only 9 g/average/day, with no differences by SEL. The results of this study show the importance of developing interventions to improve fish intake among school children

Variability of fish consumption within the 10 European countries participating in the European Investigation into Cancer and Nutrition (EPIC) study.

Thomas E. Spencer, A. Tjonneland, Walther Boer … (2002)

To describe and compare the consumption of total fish (marine foods) and the fish sub-groups - white fish, fatty fish, very fatty fish, fish products and crustacea, in participants from the European Investigation into Cancer and Nutrition (EPIC) study. Cross-sectional analysis of dietary intake using a computerised standardised 24-hour recall interview. Crude means, means and standard errors adjusted by age, season and day of the week were calculated, stratified by centre and gender. Twenty-seven redefined centres in the 10 European countries participating in the EPIC study. In total, 35 955 subjects (13 031 men and 22 924 women), aged 35-74 years, selected from the main EPIC cohort. A six- to sevenfold variation in total fish consumption exists in women and men, between the lowest consumption in Germany and the highest in Spain. Overall, white fish represented 49% and 45% of the intake of total fish in women and men, respectively, with the greatest consumption in centres in Spain and Greece and the least in the German and Dutch centres. Consumption of fatty fish reflected that of total fish. However, the greatest intake of very fatty fish was in the coastal areas of northern Europe (Denmark, Sweden and Norway) and in Germany. Consumption of fish products was greater in northern than in southern Europe, with white fish products predominating in centres in France, Italy, Spain, The Netherlands and Norway. Intake of roe and roe products was low. The highest consumption of crustacea was found in the French, Spanish and Italian centres. The number of fish types consumed was greater in southern than in northern Europe. The greatest variability in consumption by day of the week was found in the countries with the lowest fish intake. Throughout Europe, substantial geographic variation exists in total fish intake, fish sub-groups and the number of types consumed. Day-to-day variability in consumption is also high.

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

Victoria Kain, L Lera, S. Olivares Pino … (2004)

To assess the nutritional status, food consumption and physical activity (PA) habits of Chilean school children, as a baseline for developing an educational intervention. Cross-sectional study. A total of 1701 children from 3rd to 7th grade in nine schools located in three geographical regions. 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. 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. 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.
