简要总结
Nowadays, it is common to ingest beverages other than plain water, which range from flavored with a low energy input to others of high input. In Mexico, flavored beverage ingestion is believed to be displacing plain water; this phenomenon is raising concern in the health sector, due to the relation between flavored beverage intake and the increase in obesity and, consequently, chronic diseases.
Up until now, there is no instrument available to characterize the perception of the Mexican population's well-being, beliefs and knowledge regarding plain water ingestion, nor is there an instrument capable of quantifying the daily water ingestion.
The purpose of this study is design and validate a questionnaire to identify and evaluate the perception of well-being (PWBQ) related to plain water consumption in a sample of adult men and women of the city of Cuernavaca.
详细描述
Water makes up the majority of the human body; it is vital to ingest it every day to maintain proper hydration and be able to carry out the different cellular processes that make life possible.Plain water is the ideal liquid to perform all the cellular functions without the risk of ingesting substances or elements that could bring energy or represent other risks to health.
Currently, water ingestion recommendations offered vary dramatically among individuals and populations; for instance, individuals residing in dry and hot climates, as well as athletes, may have a greater need for water. The Dietary Reference Intake (DRI) suggests that the usual daily average ingestion in adults is 3.7 liters for men and 2.7 liters for women.
In Mexico, data from national health and nutrition surveys showed that highly energetic beverage consumption, such as sodas (carbonated or not), sugar-added or sugar-free fruit juices, fresh fruit waters ("aguas frescas") with sugar added and whole or flavored milk, doubled among the Mexican population between 1999 and 2006.
As such, this study has the following specific objectives:
-
- Characterize beliefs, knowledge, attitudes and perceptions of physical well-being resulting from plain water consumption in a sample of adult men and women of the city of Cuernavaca, using qualitative techniques.
-
- Validate the instrument through a process of instrument testing and adjustment, feasibility tests (consistency, temporary stability, inter-rater reliability and sensitivity to detect a change), content validity with field experts, criterion validity correlating the instrument with health questionnaire SF-36 and finally through an intervention in order to correlate the PWBQ with urine biochemical markers (volume, osmolarity, color, density, pH, Ca, Na and K), plain water ingestion reports, physical activity levels, diet, SF-36 and LCF.
