Beverage Intake Patterns in a National Sample of Polish Adolescents: PLACE-19 Study

Insufficient hydration and high consumption of sugar-sweetened beverages (SSBs) is a significant public health challenge among adolescents. The aim of the presented study was to assess the beverage intake, in terms of quantity and choices, in a national-based population of Polish adolescents within the PLACE-19 Study.

Within the PLACE-19 Study, the population of n = 1027 secondary school adolescents (age 15-20 years) was recruited based on a quota sampling of Polish secondary schools and n = 984 individuals (n = 674 female, n = 310 male) were included in the analysis. The study assessed beverages intake using the National Youth Physical Activity and Nutrition Study (NYPANS) survey questionnaire and data were gathered using the Computer-Assisted Web Interview (CAWI) technique. The beverages were assessed in the following groups: water, milk beverages, 100% fruit juices, coffee/tea, regular carbonated soft drinks (CSDs), diet CSDs, other sugar-sweetened beverages (SSBs); additionally, total SSBs were summarized. The total beverage intake was compared with 80% of the Adequate Intake (AI) level.

The highest intake was observed for water (250 mL per day), and tea beverages (178.1 mL per day). However, in combining SSBs, the total daily intake for this group was 394.4 mL per day. The highest share of the daily intake of beverages was attributed to water intake (23.81%), and tea beverages (11.45%), followed by 100% fruit juices (7.14%), fruit drinks (6.67%), and milk (6.45%); however, the intake of total combined SSBs was even higher than for water (32.47%). Male individuals were characterized by a higher share of milk beverages, regular CSDs, diet CSDs, and other SSBs than female ones, while female individuals were characterized by a higher share of water, and coffee/tea in their total daily beverage intake than male ones (p < 0.001). Younger individuals were characterized by a higher share of other SSBs in their total daily beverage intake than older ones (p = 0.034). For the vast majority of the studied group, the inadequate intake of beverages was observed, as over 70% of the studied sub-groups did not meet the AI value.

The inadequate beverage intake in a population of adolescents may be a problem, especially considering high intake of SSBs, and relatively low intake of water. Especially in male and younger individuals, due to a higher intake of SSBs, than for female and older individuals, education is necessary to promote adequate intake and choices of beverages. Further research is needed in the area of beverage consumption to understand the determinants of beverage consumption and develop opportunities to improve it.
