Sex- and weight-specific changes in the frequency of sweet treat consumption during early adolescence: a longitudinal study
BRITISH JOURNAL OF NUTRITION(2021)
Abstract
The transition from childhood to adolescence is a sensitive period, triggering changes in health- and weight-related behaviours including eating habits which likely vary between girls and boys. We aimed to characterise the changes in the frequency of consumption of select sugary foods and drinks ('sweet treats') among 4237 Finnish girls and boys during a 2-year follow-up period. Additionally, we examined four subgroups: children whose weight or waist normalised as well as children whose weight or waist circumference increased during follow-up. An FFQ was completed at 11 center dot 1 (sd 0 center dot 9) and again at 13 center dot 4 (sd 1 center dot 1) years of age. A sum variable sweet treat index (STI, range 0-84) captured the weekly consumption frequencies of sweet treats. From baseline to follow-up, the mean STI decreased among girls from 7 center dot 1 (95 % CI 6 center dot 9, 7 center dot 3) to 6 center dot 0 (95 % CI 5 center dot 9, 6 center dot 2) (P < 0 center dot 001) and boys from 8 center dot 5 (95 % CI 8 center dot 3, 8 center dot 8) to 7 center dot 8 (95 % CI 7 center dot 6, 7 center dot 8) (P < 0 center dot 001), although both sexes increased their chocolate/sweets consumption: girls from 1 center dot 3 (95 % CI 1 center dot 3, 1 center dot 4) to 1 center dot 6 (95 % CI 1 center dot 5, 1 center dot 6) (P < 0 center dot 001) and boys from 1 center dot 4 (95 % CI 1 center dot 3, 1 center dot 4) to 1 center dot 6 (95 % CI 1 center dot 6, 1 center dot 7) (P < 0 center dot 001), and boys increased their soft drink consumption from 1 center dot 4 (95 % CI 1 center dot 3, 1 center dot 4) to 1 center dot 5 (95 % CI 1 center dot 4, 1 center dot 5) (P = 0 center dot 020). We found similar decreases in both the weight and waist subgroups. To conclude, the total frequency of consumption of sweet treats decreased during early adolescence. A similar trend across subgroups suggests that the frequency of consumption of sweet treats is unrelated to becoming overweight.
