Increases in alcohol intakes are concurrent with higher energy intakes: Trends in alcohol consumption in australian national surveys from 1983, 1995 and 2012

Abstract

This research aimed to provide the first assessment of the contribution of alcohol to Australian adults’ diets over time and determine if people reporting alcohol had higher total dietary energy intakes. Secondary analyses of cross-sectional national nutrition surveys from 1983, 1995, and 2011/12 for adults 18 years (n = 26,675) and over were conducted. Alcoholic beverage intake and diet were assessed using 24-h recalls. The proportion of participants reporting alcohol consumption declined over time and in 1983, 1995, and 2011/12 was 52.0%, 44.2%, and 39.8%, respectively, for men (p < 0.001) and 31.6%, 25.7%, and 25.7%, respectively, for women (p < 0.001). A decline in alcohol intake was seen between 1983 and 2012 for all subpopulations, except for women aged over 45 years, for whom alcohol intake increased. Energy intake was higher for participants reporting alcohol intake and the mean difference (SD) in energy intake for those reporting alcohol versus non-consumers was +1514 kJ (462) for men and +1227 kJ (424) for women. Consistent with apparent consumption data, reported alcohol intake for the total population decreased over time. As those reporting alcohol had much higher energy intakes than non-consumers, promoting alcohol intakes consistent with national recommendations may have important implications for the prevention of obesity, particularly for middle-aged women.
