Abstract
Purpose
It is the aim of the present paper to describe the nutritional intake, the physical performance capacity and certain anthropometric variables of a group of schoolchildren (n=297) aged seven to 12 years. The findings on this population may be used to give advice in specific marketing situations.
Design/methodology/approach
The subjects were asked to complete a three‐day food diary. During a school visit body weight, stature and skinfold thicknesses were measured. Physical fitness was assessed using items of the Eurofit test battery. Data analysis was carried out as a function of sex and age groups.
Findings
The study finds that 77 per cent of all subjects had a caloric intake below the recommended daily allowance (RDA), while 23 per cent had an intake above the RDA. Macronutrient analysis showed for all groups a low carbohydrate intake, a high fat intake, whilst protein intake was just near the upper limit of the RDA. Flexibility, explosive leg strength, abdominal dynamic muscular endurance and cardiovascular endurance were significantly lower when comparing these data with data of the 1990s. Significant correlations were found between the BMI values and the sum of skinfolds.
Research limitations/implications
The relations between behavioural characteristics of this age group and adaptations of dysfunctional behaviour, as well as consequences for later life, need to be further established.
Practical implications
Combining the promotion of healthy nutritional and physical activity habits is an appropriate and ethical way to improve the health and fitness status of young consumers. Products may only be linked with health if there is sufficient evidence that the normal use will lead to the pretended health advantages. The interaction with behavioural changes may result in a marketing advantage if the health implications are properly stated.
Originality/value
The paper demonstrated that, at a very young age, nutritional and physical activity habits in the self‐selected population were rather poor.
