LABRANA, Ana María  and  (EN REPRESENTACION DEL CONSORCIO DE INVESTIGACION ELHOC-CHILE) et al. Water intake in the Chilean population: Findings from the 2016-17 National Health Survey. Rev. méd. Chile [online]. 2021, vol.149, n.1, pp.52-61. ISSN 0034-9887.


Water is an essential nutrient for cellular homeostasis and life. Drinking ≥ 6 glasses (1.5 L/day) is the recommendation of daily water intake (RIAD).


To characterize water intake, according to sociodemographic, anthropometric and lifestyles variables, in the Chilean adult population.

Material and Methods:

Analysis of data from 5,520 participants of the 2016-17 National Health Survey. Compliance with RIAD by population groups according to sociodemographic, anthropometric and lifestyle characteristics was studied through logistic regression analyses.


Only 27.8% of the national population met the RIAD. Women, people over than 56 years of age, housewives, retired people, widowers, and non-smokers were less likely to meet the RIAD. The likelihood of not complying with RIAD in these segments of the population ranged from 28% to 62%. Conversely, participants who presented a higher likelihood of meeting RIAD were those who co-habiting, had a medium and higher educational level, followed a diet plan, and those who reported a good health and well-being. The likelihood of meeting with the RIAD for these population groups ranged from 47% to 116%.


The likelihood of meeting the RIAD varied according to different sociodemographic, anthropometric, and lifestyle variables. Therefore, public policies for promoting water consumption should be focused on all age groups, but especially in those groups with the highest risk of underconsumption.
