Cook It Up! A community-based cooking program for at-risk youth: overview of a food literacy intervention

BACKGROUND

In Canada, there are limited occasions for youth, and especially at-risk youth, to participate in cooking programs. The paucity of these programs creates an opportunity for youth-focused cooking programs to be developed, implemented, and evaluated with the goal of providing invaluable life skills and food literacy to this potentially vulnerable group. Thus, an 18-month community-based cooking program for at-risk youth was planned and implemented to improve the development and progression of cooking skills and food literacy.

FINDINGS

This paper provides an overview of the rationale for and implementation of a cooking skills intervention for at-risk youth. The manuscript provides information about the process of planning and implementing the intervention as well as the evaluation plan. Results of the intervention will be presented elsewhere. Objectives of the intervention included the provision of applied food literacy and cooking skills education taught by local chefs and a Registered Dietitian, and augmented with fieldtrips to community farms to foster an appreciation and understanding of food, from 'gate to plate'. Eight at-risk youth (five girls and three boys, mean age = 14.6) completed the intervention as of November 2010. Pre-test cooking skills assessments were completed for all participants and post-test cooking skills assessments were completed for five of eight participants. Post intervention, five of eight participants completed in-depth interviews about their experience.

DISCUSSION

The Cook It Up! program can provide an effective template for other agencies and researchers to utilize for enhancing existing programs or to create new applied cooking programs for relevant vulnerable populations. There is also a continued need for applied research in this area to reverse the erosion of cooking skills in Canadian society.

Factors that affect the food choices made by girls and young women, from minority ethnic groups, living in the UK

BACKGROUND

Lower birth weight, often found in infants from minority ethnic groups, may be partly because of the disproportionate representation of ethnic minority groups in low-income areas. To develop an intervention, to improve the nutritional intake of young women from populations at risk of low-birth-weight babies, which would be culturally sensitive and well received by the intended recipients, a community development approach was used to investigate factors that might influence food choice and the nutritional intake of girls and young women from ethnic minority groups.

METHODS

Focus group discussions were conducted across the UK, to explore factors that might affect the food choices of girls and young women of African and South Asian decent. The data was analysed using deductive content analysis (Qual. Soc. Res., 1, 2000, 1). Discussions were around the broad themes of buying and preparing food, eating food and dietary changes, and ideas for an intervention to improve diet.

RESULTS

The focus group discussions indicated that all the communities took time, price, health and availability into consideration when making food purchases. The groups were also quite similar in their use of 'Western' foods which tended to be of the fast food variety. These foods were used when there was not enough time to prepare a 'traditional' meal.

CONCLUSION

Many issues that affect the food choice of people who move to the UK are common within different ethnic groups. The idea of a practical intervention based on improving cooking skills was popular with all the groups.

Autonomy and control: the co-construction of adolescent food choice

We explored how adolescents and parents negotiate adolescents' increasing food choice autonomy in European Canadian, Punjabi Canadian and African Canadian families. Data were collected through semi-structured interviews with 47 adolescents and their parents, participant observation at a family meal and a grocery shopping trip with the family shopper(s). Thematic and constant comparative analyses were used. Adolescents exercised considerable autonomy over much of their food choice and their parents monitored and controlled the environment within which adolescents were given independence and responsibility. Parents used strategies of coaxing, coaching and coercing, while teens responded by complaining, ignoring and refusing their parents' advice. At the same time, teens took responsibility and reflected on their behaviours while keeping in mind their parents' advice, even if in some cases they were as yet unable to act upon it. Food choice autonomy is not simply a negative act of teenage defiance. Instead, it is actively co-constructed by both teens and their parents as each resists and responds to the others. Studies of adolescent autonomy related to food choices, and interventions based on nutritional autonomy as a risk factor for poor nutrition would do well to take account of the co-constructive parent-adolescent process of teen autonomy.

Food Preparation and Purchasing Roles among Adolescents: Associations with Sociodemographic Characteristics and Diet Quality

OBJECTIVE

To describe adolescent involvement in preparing and shopping for food and examine if extent of involvement is related to diet quality.

DESIGN

Cross-sectional study design. Past week frequency of involvement in preparing and shopping for food was self-reported on the Project EAT (Eating Among Teens) survey. Dietary intake was assessed using the Youth/Adolescent Food Frequency Questionnaire.

SUBJECTS/SETTING

Middle school and high school students from Minneapolis/St Paul, MN, public schools.

STATISTICAL ANALYSES PERFORMED

Associations between involvement and sociodemographic characteristics were examined using cross tabulations. General linear modeling was used to compare dietary intakes of adolescents across different levels of involvement in preparing and shopping for food.

RESULTS

The majority of adolescents reported helping prepare dinner (68.6%) and nearly half reported shopping for groceries (49.8%) at least once during the past week. Greater involvement in these food tasks was related to sex (female), grade level (middle school), race (Asian American), socioeconomic status (low), family meal frequency (high), and weight status (overweight). Frequency of preparing food was related to lower intakes of fat (P<0.01) and higher intakes of fruits and vegetables, fiber, folate, and vitamin A. Preparing was related to lower intakes of carbonated beverages among female adolescents (P<0.01) and lower intakes of fried foods among male adolescents (P<0.01). In contrast, food shopping frequency was related to greater consumption of fried foods among female adolescents (P<0.01).

CONCLUSIONS

Adolescents should be encouraged to help with meal preparation and may benefit from interventions and programs that teach skills for cooking and making healthful purchasing decisions.

Meal pattern, food choice, nutrient intake and lifestyle factors in The Göteborg Adolescence Study

OBJECTIVE

To relate meal pattern of Swedish adolescents to food choice, nutrient intake and other lifestyle factors.

DESIGN

Cross-sectional study including diet history and interview about smoking, ethnicity, social factors and retrospectively collected data of menarche and growth.

SETTING

School setting, Göteborg, Sweden.

SUBJECTS

A total of 611 boys and 634 girls in grade 9 (15-16 y).

RESULTS

The majority of the students, 65% of the boys and 52% of the girls, consumed three main meals daily. The in-between meals, however, contributed the major part of the energy intake. The energy intake was 12.9+/-3.5 MJ (mean+/-s.d.) for boys and 9.0+/-2.5 MJ for girls. Irregular breakfast eating, 12% of the boys and 24% of the girls, was related to negative lifestyle factors where smoking was the strongest, odds ratio 3.8 (95% CI: 2.6-5.4) and to irregular intake of lunch and dinner. These boys and girls had a food choice including a higher percentage of energy from snack food (26% vs 20% and 19% in boys and girls respectively, all P<0.001), mostly consumed between the main meals. These groups had significantly lower intakes of micronutrients, but higher intakes of sucrose and alcohol compared to the groups with regular breakfast intake. Girls omitting breakfasts and lunches (8%) also had a less healthy food choice and the poorest nutrient intake. These girls had matured earlier, with menarche age of 12.2+/-1.1 y vs 12.9+/-1.0 y (P<0.001) in girls with regular main meal intake.

CONCLUSIONS

Meal pattern with omission of breakfast or breakfast and lunch was related to a clustering of less healthy lifestyle factors and food choice leading to a poorer nutrient intake.

An investigation of the association between vending machine confectionery purchase frequency by schoolchildren in the UK and other dietary and lifestyle factors

OBJECTIVE

Availability of confectionery from vending machines in secondary schools provides a convenient point of purchase. There is concern that this may lead to 'over-indulgence' and hence an increase in susceptibility to obesity and poor 'dietary quality'. The study objective was to investigate the association between the frequency of consumption of confectionery purchased from vending machines and other sources and related lifestyle factors in adolescent boys and girls.

DESIGN

A secondary school-based, cross-sectional study.

SUBJECTS AND SETTING

A total of 504 subjects were investigated (age range 12-15 years), from three schools in southern and northern England. Using a lifestyle questionnaire, frequency of confectionery consumption (CC) from all sources (AS) and vending machines (VM) was recorded for a typical school week. Subjects were categorised into non-consumers, low, medium and high consumers using the following criteria: none, 0 times per week; low, 1-5 times per week; medium, 6-9 times per week; high, 10 times per week or greater.

RESULTS

No differences were found in the frequency of CC from AS or VM between those who consumed breakfast and lunch and those who did not. No differences were found in the frequency of fruit and vegetable intake in high VM CC vs. none VM CC groups, or in any of the VM CC groups. Confectionery consumption from AS (but not VM) was found to be higher in subjects who were physically active on the journey to school (P<0.01) but also higher in those who spent more time watching television and playing computer games (P<0.01). No associations were found between smoking habits or alcohol consumption and frequency of CC.

CONCLUSIONS

These results do not show a link between consumption of confectionery purchased from vending machines and 'poor' dietary practice or 'undesirable' lifestyle habits. Findings for total confectionery consumption showed some interesting trends, but the results were not consistent, either for a negative or positive effect.

Dieting patterns and related lifestyles of school-aged children in the Republic of Ireland

OBJECTIVE

The aim of this study was to identify differences in food habits and lifestyle behaviours by dieting status among young people in Ireland.

DESIGN

Cross-sectional survey. Participants responded to a self-completion questionnaire designed by researchers on the World Health Organization's collaborative study - Health Behaviour in School Aged Children. Pupils were selected by school and classroom and the sample was stratified to be representative of the geographical distribution of school students in Ireland.

SETTING

Data were collected by teachers from school pupils in their classrooms.

SUBJECTS

Data were collected from 187 schools which included 8497 pupils (51% girls) aged 9-17 years.

RESULTS

While a minority of pupils (12% of girls, 4% of boys) reported that they were on a diet to lose weight, a substantial proportion (28% of girls, 18% of boys) said that they should be on a diet. Dieters reported consuming unhealthy foods less frequently than non-dieters, but did not report an increased consumption of fruit and vegetables. Rather, some categories of dieters reported higher levels of coffee and tobacco use and lower exercise levels than non-dieters.

CONCLUSIONS

The results could indicate substitution of unhealthy foods by other unhealthy behaviours as opposed to an increased consumption of healthier foodstuffs, and suggest that both smoking and exercise need to be addressed alongside nutrition in youth health promotion.

Consumo alimentar de adolescentes matriculados em um colégio particular de Teresina, Piauí, Brasil

Com o objetivo de estudar o consumo alimentar de adolescentes matriculados em um colégio particular de Teresina, realizou-se estudo transversal através de amostragem sistemática. A freqüência de consumo de alimentos expressa em dias por semana foi obtida mediante questionário administrado individualmente ao aluno. O estado nutricional foi avaliado pelo Índice de Massa Corporal, considerando com sobrepeso valores > ou = P85. Os resultados indicam prevalência elevada de risco para o sobrepeso (19,8%) nos 334 adolescentes. Os meninos consumiram com maior freqüência alimentos energéticos (milho, manteiga, pizza, lasanha, sucos industrializados, refrigerantes) e construtores (frango, ovos, leguminosas) em relação às meninas (p < 0,05). Os adolescentes de 10 a 13 anos consumiram com maior freqüência milho, mel, açúcar, rapadura enquanto aqueles com idade entre 17 e 19 anos consumiram mais arroz, bolos, biscoitos, rosca, balas, goma de mascar, refrigerantes, frutas verde-amarelo.

Cross-sectional measurement of nutrient intake among adolescents in 1996

BACKGROUND

Many components are involved in an assessment of diet and health among youth. To address these issues and document the major contributions of fat, fiber, vitamins, and minerals to the diet, we analyzed baseline cross-sectional data from a cohort of 16,882 youth.

METHODS

Cross-sectional analyses were conducted on the Growing Up Today Study dietary data reported by 16,882 9- to 14-year-olds in 1996. The adolescent food frequency questionnaire was used to assess this age group's eating habits. Arithmetic means and standard deviations were calculated on energy-adjusted and unadjusted data.

RESULTS

Mean intake (including vitamin/mineral supplementation) for all nutrients met 100% of the RDAs, except calcium for girls. Comparing the servings of foods with the USDA Food Pyramid, neither boys nor girls met recommended number of servings except for dairy. Overweight participants consumed fewer kilocalories and lower levels of nutrients than their nonoverweight peers.

CONCLUSION

These cross-sectional data from 1996 indicate that this cohort is consuming foods and nutrients comparable with national data of less fat and more carbohydrates in their diet. Overweight participants have similar dietary patterns except for total energy. The cohort's diet (with vitamin/mineral supplementation) is meeting the RDAs, but actual foods consumed suggest a lack of balance in the diet.

Dietary trends among Scottish schoolchildren in the 1990s

BACKGROUND

In recent years, healthy eating messages have sought to highlight the advantages of a healthy balanced diet, but there is little evidence that the recommendations have been translated into sustained behavioural change. In Scotland, the national diet has become a major focus in key policy documents, and the diet of children and young people has been consistently highlighted as an area of particular concern. This paper reports on dietary trends among Scottish schoolchildren during the 1990s.

METHODS

Data were collected from a representative sample of Scottish schoolchildren as part of the WHO Cross-national Health Behaviour of School-aged Children (HBSC) study. Three consecutive national surveys were undertaken in Scotland, in 1990, 1994 and 1998, using self-completion food frequency questionnaires with 11-, 13- and 15-year-old school pupils.

RESULTS

Between 1990 and 1998, fruit and vegetable consumption increased among Scottish schoolchildren, especially among girls, but levels of consumption fell below current dietary recommendations. There has been a concomitant increase in consumption of high-fat and high-sugar foods, and consumption of these foods is higher among boys and children from lower socio-economic groups.

CONCLUSION

The findings emphasize the need for continued health promotion efforts to improve the diet of schoolchildren in Scotland especially among lower socio-economic groups.

Measurement of plasma F2-isoprostanes as an index of lipid peroxidation does not appear to be confounded by diet

F2-isoprostanes (F2-IPs) are formed by the free radical-catalysed oxidation of arachidonic acid. The measurement of F2-IPs, especially 8-epi-PGF2alpha, is recognised as a reliable marker of lipid peroxidation and is currently used as a sensitive index of oxidative stress in vivo. The majority of 8-epi-PGF2alpha present in the circulation occurs in association with lipoproteins which are synthesised in the liver. Since lipoproteins are derived from dietary fatty acids and triglycerides, it is possible that 8-epi-PGF2alpha generated in polyunsaturated fatty acid-rich food (during initial processing/packaging or during meal preparation) may become incorporated within these lipoproteins during synthesis. In view of the growing use of 8-epi-PGF2alpha as a marker of lipid peroxidation in vivo in nutritional or clinical studies, it is therefore important to investigate the possibility that the circulating levels measured could be confounded by the presence of 8-epi-PGF2alpha in food. In this study we evaluated the levels of 8-epi-PGF2alpha present in several popular fast-foods, using a combination of solid phase extraction and gas chromatography-mass spectrometry. Fast-foods were selected to represent meals prepared from vegetable-, chicken-, fish- and meat-derived ingredients. Total (free + esterified) 8-epi-PGF2alpha levels ranged from 0.09 to 0.73 pmol/g (122-644 pmol/mmol arachidonic acid), with the highest levels present in beef-derived meals. Further investigation of hamburgers and cheeseburgers revealed 8-epi-PGF2alpha levels of 1.83 +/- 0.24 and 0.84 +/- 0.03nmol/mmol arachidonic acid, respectively. Lower concentrations of vitamin E were found in the hamburgers. The postprandial contribution to plasma 8-epi-PGF2alpha levels following ingestion of 100 g portions of these fast-foods would therefore be expected to be no greater than the low picomole range, and would be unlikely to influence the normal endogenous levels of 8-epi-PGF2alpha and those produced during oxidative stress.

Evaluation of the postprandial effects of a fast-food meal on human plasma F(2)-isoprostane levels

Measurement of the F(2)-isoprostane, 8-epi-PGF(2alpha) is increasingly used as a sensitive and reliable marker of lipid peroxidation in vivo. Because the majority of 8-epi-PGF(2alpha) in plasma is associated with lipoproteins, it is possible that 8-epi-PGF(2alpha) derived from polyunsaturated fatty acid-rich food may become incorporated within these lipoproteins during synthesis and could contribute to the levels detected in plasma. In this study, we evaluated the postprandial effect of a single fast-food meal (McDonald's Big Mac meal, McDonald's Corp., London, England) on plasma total 8-epi-PGF(2alpha) in nine healthy subjects. Blood was collected before and 2 h postprandially. 8-Epi-PGF(2alpha) was measured by immunoaffinity extraction and gas chromatography-mass spectrometry. Fasting plasma 8-epi-PGF(2alpha) (875 +/- 25 pM) increased postprandially (956 +/- 23 pM, p <.05), although no significant change was observed in the normalized concentrations (2. 78 +/- 0.1 vs. 2.95 +/- 0.3 nmol/mmol arachidonic acid). Plasma lipid hydroperoxides, fatty acids, vitamin E, total antioxidant status, cholesterol, and triglycerides were not altered. Plasma glucose increased postmeal (4.4 +/- 0.1 vs. 4.9 +/- 0.1 mM, p <.05). These results indicate that the overall contribution of this lipid-rich meal to plasma 8-epi-PGF(2alpha) and other lipid peroxidation markers was small.
