Grandchildren's food workshop: Impact of an intergenerational cooking program on dietary habits, food courage, cooking skills and two-way interaction in Danish children and their grandparents.

BACKGROUND: Good nutrition is a key aspect of health. Cooking activities can improve dietary habits, cooking skills and food courage in terms of courage to cook and taste new foods, in individuals of all ages. However, targeting both grandchildren and grandparents at the same time through intergenerational cooking activities, is new. AIM: This paper aims to present the impact of intergenerational cooking activities on dietary habits, food courage, cooking skills and two-way interaction between young and old participants in The Grandchildren's Food Workshop. METHODS: In this observational pilot study, the Danish Heart Foundation's experimental cooking program for grandchildren and grandparents was developed and tested. The influence of the food workshop on the participants' dietary habits, food courage, cooking skills and two-way interaction was assessed by a before and after questionnaire. McNemar's and chi-squared tests were used to evaluate the effects. RESULTS: A total of 180 grandchildren (10 to 12 years) and 183 grandparents participated in The Grandchildren's Food Workshop. A total of 82 (46%) grandchildren (71% of which were girls) and 125 (68%) grandparents (83% of which were women) responded to the baseline and follow-up questionnaires. The impact on dietary habits and food courage was limited, while there was an impact on cooking skills in the grandchildren. The already good two-way interaction was unaltered. CONCLUSIONS: The findings indicate an impact on cooking skills among grandchildren participating in The Grandchildren's Food Workshop, while the impact on dietary habits, food courage and two-way interaction between age groups was limited. Further research, including more detailed dietary data, should explore the significance of an intergenerational approach.

Overall glycaemic index and glycaemic load of habitual diet and risk of heart disease.

OBJECTIVE: To test the hypothesis that diets with high glycaemic index (GI) and glycaemic load (GL) increase the risk of heart disease. DESIGN: Overall GI and GL were assessed from 7 d diet records or diet history interviews. SETTING: Information on hospitalization and death due to CVD and CHD was obtained from the National Register of Cause of Death and the National Register of Patients. SUBJECTS: In total 3959 adult Danes were - depending on time of entry - followed for 6-25 years until 31 December 1999. RESULTS: Overall GI was inversely associated with heart disease in men. The hazard ratios (95 % CI) for the 10th and 90th GI percentiles compared with the median were 1.38 (1.13, 1.68) and 0.90 (0.76, 1.07) for CVD morbidity, 1.45 (1.05, 1.99) and 0.81 (0.62, 1.06) for CVD mortality, and 1.31 (0.97, 1.76) and 0.65 (0.51, 0.84) for CHD morbidity. In male subjects GL was not associated with either outcome. In women no clear association between overall GI and heart disease was found, whereas positive non-linear associations were found for GL: at very high levels of GL, increase in GL was associated with increasing CVD and CHD morbidity. CONCLUSIONS: In men low-GI diets were associated increased risk of heart disease and GL was not associated with heart disease. In women there was no clear association between GI and heart disease, but to some extent a positive association between GL and heart disease was observed as hypothesized.

Dietary carbohydrates and change in physical performance of elderly Europeans: Survey in Europe on Nutrition and the Elderly, a Concerted Action (SENECA) 1993 and 1999.

OBJECTIVE: To study dietary glycaemic index (GI) and glycaemic load (GL) in association with physical performance in elderly Europeans. DESIGN: Cross-sectional and prospective study. Physical performance was measured using the Physical Performance Test (PPT) score on a scale from 0 to 27, where high scores indicate a better physical performance. Habitual diets were measured using diet history interviews and dietary GI and GL were estimated from table values. SETTING: Eight towns/centres from the Survey in Europe on Nutrition and the Elderly, a Concerted Action (SENECA) in 1993 and 1999. SUBJECTS: Seven hundred and sixty-five men and women, 75-80 years old, were examined in 1993; of these, 357 (47 %) were followed up in 1999, at age 80-85 years. RESULTS: At baseline, both dietary GI and GL were significantly inversely associated with PPT scores (P = 0.03 and P = 0.05, respectively). When adjusted for age, BMI, physical activity, self-perceived health, chronic diseases and town/centre, the strength of the associations was attenuated and became non-significant (GI, P = 0.08; GL, P = 0.92). Dietary GI/GL were not associated with PPT scores 6 years later. CONCLUSIONS: Among elderly Europeans, a high glycaemic diet was associated with a low physical performance at baseline but not 6 years later. Cross-sectional associations may in part be caused by variations in age, BMI, physical activity, self-perceived health, chronic diseases and geographic location.

Dietary glycaemic index and glycaemic load in Danish children in relation to body fatness.

The aim of this study was to describe dietary glycaemic index (GI) and glycaemic load (GL) values in the diets of Danish children, and to examine the associations between dietary GI, GL and body fatness. Data were collected during 1997-8 as part of the European Youth Heart Study. The study population comprised 485 children aged 10 years and 364 children aged 16 years from Odense County, Denmark. Dietary GI and GL were estimated using international food tables, and the associations between energy-adjusted dietary GI, GL and body fatness were analysed by multiple linear regression. The mean daily dietary GI value was 85 (SD 6.9) with a range of 62-111. No significant differences were found between age groups and gender. The daily dietary GL was higher among boys aged 16, with a GL of 330 (sd 95) (P<0.05), compared with girls or younger boys. Dietary GL was higher among 10-year-old boys than girls (250 (sd 81) v. 230 (sd 66) P<0.05), whereas dietary GL among 16-year-old girls was 230 (sd 56). Neither dietary GI nor GL was associated with the sum of four skinfolds (SigmaSF) among girls or among 10-year-old boys. Among 16-year-old boys, significant associations were observed between dietary GI and SigmaSF (beta=0.60, SE=0.21, P=0.006), and between dietary GL and SigmaSF (beta=0.15, SE=0.06, P=0.009). In conclusion, dietary GI and GL were positively associated with body fatness among Danish boys aged 16 years, whereas no associations were found among girls or younger boys.
