Water and beverage consumption: analysis of the Australian 2011-12 NNPAS

07 / 02 / 17

This paper is yet another analysis of the rich source of data from the Australian NNS, this time on what beverages we drink. Usual water and fluid intakes were estimated. Total water includes plain drinking water and moisture from all foods and beverages; total fluids include plain drinking water and other beverages but not food moisture.

The mean daily total water for children and adolescents 2-18 yrs was 1.7L (males) and 1.5L (females), and adults 19yrs+ 2.6L (males) and 2.3L (females). The majority of the population failed to meet the AI (adequate intake) for total water (82%) and total fluids (78%), with the elderly at highest risk (90-95%). Plain drinking water contributed 44% to the total for children and adolescents, and other beverages contributed 27%, the main sources were whole milk and regular soft drinks. In adults, 37% total water came from plain drinking water, and 37% from other beverages, the main sources were tea, coffee and alcohol.

In adults, higher total water intake was associated with lower percentage energy intake from fat, saturated fat and free sugars, lower sodium and lower energy dense nutrient poor foods, and higher intakes of dietary fibre, fruit, vegetables, caffeine and alcohol. No associations were found between total water consumption and body weight measures in adults or children.
