There is no complete explanation for the association between socioeconomic status (SES), fibre, and whole diet described by dietary patterns. The aim of this short report was to increase the understanding of adolescent dietary patterns related to fibre in their social context. A cross-sectional study was conducted involving 1176 adolescents aged 13–18 years from central and north-eastern Poland. The overall SES was composed of five single factors: place of residence, self-declared economic situation of family, self-declared economic situation of household, paternal and maternal education. The consumption frequency of nine dietary fibre sources was collected using Block’s questionnaire and was expressed in points. Fibre dietary patterns (DPs) were drawn by cluster analysis and odds ratios (ORs) adjusted for age, sex, and BMI were calculated. Three fibre-related DPs were identified: “High-fibre” (mean frequency of total fibre intake 22.7 points; range: 0–36), “Average-fibre” (17.7 points), “Low-fibre” (14.6 points). The “High-fibre” DP was characterized by a relatively higher frequency consumption of white bread, fruit, fruit or vegetable juices, potatoes, green salad and prepared vegetables, and a moderate frequency consumption of high-fibre or bran cereals and wholegrain bread compared to the “Low-fibre” DP. The “Average-fibre” DP was characterized by a relatively higher frequency consumption of wholegrain bread and high-fibre or bran cereals and a moderate frequency consumption of fruit, fruit or vegetable juices, green salad and prepared vegetables compared to the “Low-fibre” DP. Less likely to adhere to the “High-fibre” DP were adolescents with low SES (OR: 0.55, 95% CI: 0.39–0.77) or average SES (0.58, 95% CI: 0.41–0.81) in comparison with high SES (reference) as a result of elementary or secondary paternal or maternal education, rural residence, and lower household economic situation. Similar associations were found for the “Average-fibre” DP. Low and average socioeconomic status resulting from lower parents’ education, rural residence, and lower economic situation were inversely associated with achieving a relatively high fibre intake in Polish adolescents. Consuming single high-fibre foods was not sufficient to achieve a high-fibre diet in Polish adolescents. These data suggest that the consumption of a wide variety of dietary fibre sources—both relatively high-fibre and low-fibre foods—may help Polish adolescents in achieving a relatively high-fibre diet.

The role of the family environment in regards to dairy products and dietary calcium in the context of obesity is not fully understood. The aim of the study was to investigate the association among dairy-related dietary patterns (DDPs), dietary calcium, body weight and composition in mothers and daughters. Data were collected through a cross-sectional survey within the MODAF Project. A total sample of 712 pairs of mothers (<60 years) and daughters (12–21 years) was studied. This study included 691 pairs. A semi-quantitative food frequency questionnaire (ADOS-Ca) was used to collect dietary data. Waist circumference (WC), body fat, waist-to-height ratio (WHtR) and body mass index (BMI) were determined. Previously derived DDPs were used—three in mothers and three in daughters. In mothers, two of the DDPs were characterized by higher consumption of various dairy products with suboptimal calcium content (means: 703 or 796 mg/day) which decreased the chance of: z-WC > 1 standard deviation (SD), WC > 80 cm, body fat > 32%, WHtR > 0.5, BMI = 25–29.9 kg/m2 or BMI ≥ 30 kg/m2 by 44–67% when compared to low-dairy low-calcium DDP (288 mg/day). In mothers per 100 mg/day of dietary calcium, the chance of z-WC > 1SD, WC > 80 cm, z-WHtR > 1SD, WHtR > 0.5 cm, BMI = 25 to 29.9 kg/m2 or BMI ≥ 30 kg/m2 decreased by 5–9%. In correspondence analysis, a clear association was found between mothers’ and daughters’ low-dairy low-calcium DDPs and upper categories of z-WC (>1 SDs). This study reinforces evidence of the similarity between mothers and daughters in dairy-related dietary patterns and provides a new insight on the adverse relation between low-dairy low-calcium dietary patterns and obesity. It was found that diets containing various dairy products with suboptimal dietary calcium content may be recommended in obesity prevention.

in children's and adolescent's diets and was related to a lower intake of calcium, riboflavin, vitamin A, folate and vitamin C [Harnack et al., 1999].The sugars contained in fruit juices and sweetened beverages are easily digestible carbohydrates which "raise blood glucose and insulin concentrations rapidly and dramatically" [Malik et al., 2010]. Insulin insensitivity is associated with the loss of hormonal satiety signals [Bray et al., 2004;Bocarsly et al., 2010]. However, there is a difference in insulin response depending on the kind of added sugar to food. The digestion, absorption, and metabolism of fructose differ from those of glucose [Bray et al., 2004]. Results from both short-term and long-term studies show that fructose consumption results in decreased circulating levels of insulin and leptin when compared with glucose [Stanhope & Havel, 2008]. Insulin and leptin act as key signals in the long-term regulation of energy balance, trough inter alia regulation of food consumption [Bray et al., 2004;Stanhope & Havel, 2008]. Long-term consumption of high fructose-diet can lead to an increasing energy intake and decreasing energy expenditure, consequently contributing to overweight and obesity [Bray et al., 2004;Stanhope & Havel, 2008]. Fructose and glucose differently affect also lipids homeostasis. Hepatic metabolism of fructose favors de novo lipogenesis [Bray et al., 2004]. High consumption of fructose increases postprandial triacylglycerol concentrations, plasma apoB-concentrations and cholesterol LDL [Stanhope & Havel, 2008]. In long-term The aim of the study was to analyse the differences in the consumption frequency of fruit juices and sweetened beverages according to gender, age and the prevalence of overweight. The study involved 1,700 adolescents aged 13-19 from north-eastern Poland. The frequencies of juices and beverages consumption are presented in 5 categories: from less than once a week to daily. On the basis of measurements of body weight and height the relative body mass (rBMI) is calculated, using standardization by Cole. The study showed that 77.8% of the sample had normal weight and 16.9% were overweight. Girls more often consumed fruit juices than boys and sweetened beverages less often. Girls with age drank less frequently fruit juices and sweetened beverages. Among boys, only the frequency of fruit juice consumption decreased with age. Daily consumption of sweetened beverages among young people increased the risk of being overweight by more than 60% compared to young people consuming them once a week. The frequency of consumption of fruit juices and sweetened beverages was more strongly related to age and sex than to body mass. The prevalence of overweight among adolescents was associated with the frequency of sweetened beverage consumption, but not with the frequency of fruit juice consumption.

SUMMARY Aim:The aim of this observational study was to investigate the intake of dietary fibre and its sources among Polish adolescents according to prevalence of overweight after adjustment for age and gender.Method: The study sample consisted of 1,565 students, including 48% boys and 52% girls aged 13-18 with normal weight, overweight and obesity. Dietary information was reported using the Block Screening Questionnaire for Fruit/Vegetable/Fibre Intake. The nutritional status was assessed on the basis of body mass and height measurements. The statistical analysis used one-factor logistic regression, multiple linear regression, trend estimation and a comparison of mean values.Results: Adolescents consuming white bread and rolls with a frequency ≥ 4 times/week had OR = 0.74 (95% CI 0.56-0.97) for overweight and obesity compared to adolescents with less frequent consumption. For other fibre sources and overall dietary fibre no significant differences were noted in consumption frequency between adolescents with normal weight and overweight/obesity. Overall, boys were more often overweight and obese than girls. Girls had a higher intake of dietary fibre, fruit, fresh vegetables, dark bread and rolls, and lower intake of potatoes, beans and white bread and rolls than boys. Older age was associated with a decrease in the consumption of fruit juices, fruit, potatoes, white bread and rolls, and dietary fibre in girls and a decrease in fruit and fresh vegetable consumption in boys.Conclusion: The intake of dietary fibre was not associated with the prevalence of overweight. As to the fibre sources, only a higher consumption of white bread and rolls decreased the chance of the occurrence of adolescent overweight. The consumption of dietary fibre and its sources was related to the age and gender of adolescents.
