Title: The impact of fruit and vegetable consumption on health, growth and development of children aged 6-9 years
Introduction: A major problem in the field of Public Health is the expansion of childhood obesity in the last years, as well as its impact on adulthood. A balanced diet during childhood, based on fruit and vegetable consumption, seems to influence children’s weight and obesity.
Purpose: The present study aims at evaluating the influence of a Health and Nutrition education program on fruit and vegetable consumption by school aged children. Furthermore, fruit and vegetable consumption was studied in relation to obesity rates, physical activity, nutrient intake and eating habits.
Material and Method: A Health and Nutrition education program was applied to a sample comprised of children attending 1st, 2nd and 3rd grade in the Prefecture of Chania, aged 6-9 years, during the school year 2006-07. After the end of the one-year intervention, nutrition habits of the sample were examined on the basis of a three-day food record, comparing the data arising from the 242 pupils of the intervention group and the 247 pupils from the control group, where there was no intervention. Daily fruit and vegetable consumption was categorized in ≤150gr/day, 151–300gr/day and >300gr/day.
Results: There were no significant statistical differences observed among the intervention and the control group in fruit and vegetable consumption by the end of the intervention program (intervention group: 248gr, control group: 249gr). Significant differences were surprisingly found in waist to hip circumference (intervention group: 0.89, control group: 0.86; p<0.001) and waist to height circumference in the control group comparing with the intervention group, although the body mass index did not demonstrate significant difference between the two groups. Along with increased fruit and
vegetable consumption, particularly in ≤150gr/day and >300gr/day categories, waist circumference was significantly decreased (62,7 and 60,7 in the two categories) and MVPA was significantly increased (64, 85 and 111 min/week in the three categories, p<0.05) in the intervention group comparing with the control group. Similarly, saturated fat intake decreased in the control group (16.2, 15.6 and 14.1 respectively; p<0.01) as well as soft drinks, juice drinks, sweets and sugar consumption (111, 67 and 43 respectively; p=0.002).
Conclusion: Fruit and vegetable consumption is generally associated with health and childhood obesity. Nevertheless, the educational intervention of the present study, due to short duration, could not affect body measurements. Thus, a longer lasting intervention maybe starting in preschool years, is necessary in order to achieve lasting results.
