Surveys Of Beverage Consumption,Knowledge And Study On Beverages Hydrating Effect Of A Higher Vocational College

Objectives:To understand the awareness of a Higher Vocational College students’ knowledge about beverage, investigate students’ daily drinking water sources, times and amount, and provide scientific basis for rational consumption of drinks through analyses of water intake and beverage consumption and studies on the replenishment effect of water to promote some relative knowledge of beverage.Approaches:All students in West Anhui Health Vocational College as the investigation object, using stratified cluster sampling method, divide all the students in West Anhui Health Vocational College into Secondary and Junior college periods, and randomly select from each of the 4 classes of students as the object of investigation. Investigate drinking water sources, times, amount, analyses of water intake and beverage consumption, knowledge of beverage and the replenishment effect of water respectively.Results:(1) Drinking water sources, times and amount survey:investigate 555 students altogether and recycle 545 questionnaires. The recycling rate is 98.2%, including 537 valid questionnaires, and the effective rate is 96.8%. There are 510 qualified questionnaires and the effective rate is 91.9%.510 survey participants’daily plain boiled water amount occupies 61.8% of the total drinking water amount; the proportion of bottled water is 20.4%, drinks 13.8% and tea 4.0%. The average drinking times are 5.9±2.1, the minimum value is 1, the maximum is 13 and the median is 6. Drinking times mainly concentrate in 4 to 7 times, taking up 69.6%(355/510). The students who drink 5 times a day take the largest part, taking up 22.9%(117/510). Daily drinking water amount is distributed in a partial state, and the average drinking water quantity is 1350±689ml. The minimum value is 85 ml, the maximum is 5550ml and the median is 1350 ml.(2) Analysis of drinking water quantity and beverage consumption:Junior college students’daily plain boiled water drinking quantity (1095 ml) is higher than that of secondary specialized school students’(1045ml) and the difference is statistically significant (Z=-2.676, P< 0.01); junior college students’total daily drinking water quantity (1350 ml) is higher than that of secondary specialized school students’(1120ml) and the difference is statistically significant (Z=-3.374, P= 0.007); city students’ daily beverage consumption (295 ml) is higher than that of country students’(143 ml) and the difference is statistically significant (Z=-2.804, P= 0.005); city students’ total daily drinking water quantity (1402 ml) is higher than that of country students’(1200 ml) and the difference is statistically significant (Z=-2.699, P= 0.007); only children’s daily beverage consumption (303 ml) is higher than that of non-only children’s (141ml) and the difference is statistically significant (Z=-3.956, P< 0.01); the daily beverage consumption of students with good economic conditions (204ml) is higher than that of the students with average economic conditions(142ml) and the difference is statistically significant (Z=-1.987, P< 0.05); the daily plain boiled water drinking quantity(1125 ml) and the total daily drinking water quantity (1293 ml)of the students carrying cups in daily life are higher than those of the students without cups (850 ml、1106 ml) but their daily beverage consumption(163 ml) is lower than that of the students without cups(204 ml) and the difference is statistically significant (plain boiled water:Z=-5.040, P< 0.01; beverage; Z=-2.419, P< 0.05; total drinking water quantity:Z=-2.924, P<0.01).(3) Investigation of the knowledge of drinks:girls know better than boys about the role of food additives in drinks and whether soups have a good replenishment effect, (56.6%vs 40.5%) and (62.7%vs 50.6%) respectively and the difference is statistically significant. Secondary specialized school students know better than junior college school students about whether drinking water quantity and drinks can replace water, drinks having clear relationship with dental caries and the role of food additives in drinks. Comparing only children with non-only children, non-only children know better about recommending drinking water quantity (11.7%vs 4.0%). Comparing the awareness rate of the knowledge about drinks of students with different economic conditions, the result is that students with poor economic conditions know better about recommending drinking water quantity, and the difference is statistically significant.(4) The replenishment effect of drinks:as for the times of filling water, the intergroup difference is statistically significant (P=0.011) and the drinks replenishment of the tea group is the least; as for the supply water amount, the intergroup difference is statistically significant (P<0.001), the plain boiled water group is the maximum and higher than the beverage with milk and cola group, the tea group is the minimum after pairwise comparison, the difference is statistically significant(P<0.05); as for the instant RPE, the intergroup difference is statistically significant (P=0.019), the plain boiled water group is higher than the tea, beverage with milk and cola group after pairwise comparison, the difference is statistically significant(P<0.05); as for 10 min RPE, the plain boiled water group is lower than the tea, beverage with milk and cola group after pairwise comparison, the difference is statistically significant(P<0.05).Conclusion:Plain boiled water, bottled water, tea and beverage are all the sources of replenishment drinking water for students. The median of daily drinking water quantity reach the recommended intakes of Dietary Guidelines for Chinese Residents (2007). Students’ daily beverage consumption are affected by the origin of student, whether only or non-only children and economic conditions. Knowledge of beverage is not comprehensive, plain boiled water match with a small amount of drink is effective to relieve thirst timely.
