Urinary sucralose levels were measured to assess adherence. A total of children were included in this trial. At baseline, children consumed an average of 1.

break, and 1. BMI z score increased significantly more over the month trial among the children randomized to the sugar-containing drink 0. Weight also increased more in the group randomized to sugar-containing drinks compared to those randomized to the sugar-free drinks 7.

The investigators conducted a well-designed trial to examine the effects of substituting sugar-free beverages for sugar-containing beverages. Significant benefits in weight and fat mass were observed.

Generalization to children in other countries would be of interest. If the consumption of sugar-containing beverages is higher among children in the United States, the potential for significant reductions in weight and fat mass may have significant public health implications.

A Trial of Sugar-Free or Sugar-Sweetened Beverages and Body Weight in Children Sep 21, Study Questions: Does replacement of sugar-containing beverages with noncaloric beverages affect weight and adiposity among normal-weight children?

Methods: The investigators enrolled normal-weight children ages 4 years, 10 months to 11 years, 11 months in an month trial. Results: A total of children were included in this trial.

Conclusions: The investigators concluded that replacement of sugar-containing beverages with sugar-free beverages can reduce weight gain and fat accumulation among normal-weight children. However, this has not been tested in long-term trials. We randomized children aged years to receive mL per day of an artificially sweetened sugar-free beverage or a similarly looking and tasting sugar-sweetened beverage.

We measured satiety on a 5-point scale by questionnaire at 0, 6, 12 and 18 months. We calculated the change in satiety from before intake to 1 minute after intake and 15 minutes after intake.

We then calculated the odds ratio that satiety increased by 1 point in the sugar-group versus the sugar-free group. We also investigated how much the children liked and wanted the beverages. We found no statistically significant difference in satiety between the sugar-free and sugar-sweetened group; the adjusted odds ratio for a 1 point increase in satiety in the sugar group versus the sugar-free group was 0.

The sugar-group liked and wanted their beverage slightly more than the sugar-free group, adjusted odds ratio 1. Sugar-sweetened and sugar-free beverages produced similar satiety. Therefore when children are given sugar-free instead of sugar-containing drinks they might not make up the missing calories from other sources.

This may explain our previous observation that children in the sugar-free group accumulated less body fat than those in the sugar group.

Recent trials have shown that sugar-free beverages lead to less weight gain than sugar-sweetened drinks[ 1 , 2 ]. A possible explanation is that sugars in solution are detected incompletely by receptors that determine satiation. As a result, sugar-free and sugar-containing drinks should produce similar degrees of satiety[ 3 ], and intake of calories from other foods is not affected[ 4 ].

Previous studies indeed showed that masked replacement of sugar-containing beverages with sugar-free beverages was only partly compensated for by an increased energy intake[ 5 , 6 ]. Small experiments lasting a few days[ 7 , 8 , 9 ], or a few weeks[ 10 , 11 ] showed that satiety following sugar-containing and sugar-free artificially sweetened drinks was similar.

However, data from large, long-term double blind trials are lacking, especially in children. Liking and wanting are food rewards that also influence food intake[ 12 ]. Liking reflects the immediate experience or anticipation of pleasure from eating a food, i.

Wanting is the intrinsic motivation to engage in eating a food, now or in the near future[ 13 ]. A four-week study in adults found that sugar-free beverages were preferred less than sugar-containing beverages[ 10 ], but another study failed to confirm this[ 11 ].

Again, large long-term trials are lacking. We therefore investigated satiety, liking and wanting in DRINK, a double-blind randomized controlled trial in which children replaced their habitual daily sugar-containing drink with either a sugar-free or sugar-sweetened beverage for 18 months[ 1 , 14 ].

Written informed consent was provided by a parent or guardian who had obtained assent from the child. The Medical Ethical Committee of VU University Medical Centre Amsterdam approved the study protocol.

The protocol for this trial and supporting CONSORT checklist are available as supporting information; see Checklist S1 and Protocol S1.

The primary objective of the DRINK trial was to examine the effect of masked replacement of sugar-sweetened beverages with noncaloric, artificially sweetened beverages on weight gain. The design and results have been reported[ 1 , 14 ]. Here we report effects on satiety, liking and wanting.

DRINK was an month double-blind randomized controlled trial in children aged living near Amsterdam, the Netherlands. Participants were individually randomized to receive either ml per day of a sugar-free, artificially sweetened beverage with 0 kcal sugar-free group or a similar sugar-sweetened beverage that provided kcal sugar group.

For the present study, only participating children in the two highest school grades were eligible because young children would not be able to understand the questionnaire. All of them proved willing and able to participate, and were enrolled Figure 1.

We recruited participants between August and November [ 14 ]. Treatment started between November 14 and December 7, The trial lasted We interrupted treatment for 1.

In the sugar-free group, allergy was reported as an adverse event for one child. In the sugar-group, allergy was reported as an adverse event for one child, and weight increase was reported as an adverse event for one child. Dutch primary school children habitually bring a snack and a beverage to school for the morning break.

We replaced the beverage brought from home with our study beverages. We provided children with 1 can per day of a noncaloric, artificially sweetened, noncarbonated beverage or a sugar-sweetened noncarbonated beverage.

We developed custom drinks for this study to ensure that the sugar-free and sugar-sweetened drinks tasted and looked essentially the same. The identical-looking ml cans provided either 0 or 26 g of sucrose 0 or kcal per day. The sugar-free beverages contained 34 mg sucralose and 12 mg acesulfame K as sweeteners.

After the DRINK trial of 18 months the large majority of children were unable to guess whether they had received sugar-sweetened or sugar-free drinks[ 1 ]. Each week children received a box at school labelled with their name and containing 8 cans, 1 for each day of the week plus 1 extra to be used as a spare in case a can was misplaced.

We offered beverages in four flavours: raspberry, peach, lemon and mango. Flavours were rotated every two weeks.

We measured satiety, liking and wanting with a questionnaire Figure 2 ; Supporting information, Appendix S1. The satiety scale has been validated in children aged years old who indicated satiety produced by three different imagined eating situations[ 15 ].

Children showed different outcomes for each meal suggesting that our satiety scale indeed measures satiety. Leon et al. compared three methods to measure liking in children aged 4 to 10 years old[ 16 ]. They concluded that the scale used by us provides a reliable and valid estimate of liking in children aged years.

The wanting scale has been used earlier [ 17 ] but has not been formally validated yet. The timeline is indicative because each school had its own timing of the morning break. Children completed a single questionnaire of satiety, liking and wanting on one day every 6 months.

They did this during the am morning break when they consumed their study drink and snack. The teachers instructed the children explicitly how to fill out the questionnaire and to consume their drink.

The teacher also asked them to write down in the questionnaire whether they had finished the contents of the can. One researcher was present at each school and circulated between school classes during the measurements. The children filled out the questionnaires themselves without assistance.

We measured satiety, liking and wanting on 5-point scales; 1 indicated low levels, and 5 high levels Supporting information, Appendix S1. We measured satiety three times on each test day: just before intake of the study beverage and the food brought from home, 1 minute after intake, and 15 minutes after intake[ 3 ].

We measured wanting 1 minute before and liking 1 minute after intake. The questionnaire also inquired about snack consumption, i. the amount and type of food eaten with the study beverage.

We calculated the calories in these snack food[ 18 , 19 ]. We present outcome variables as medians and interquartile ranges. We used generalized linear mixed model analysis in STATA SE 12 StataCorp LP, Texas, USA. The generalized linear mixed model analyses took into account the repeated measurements at 0, 6, 12 and 18 months, and the ordinal structure of the 5-point scales.

For children who discontinued beverage intake we included the data obtained up until discontinuation. We calculated regression coefficients for the likelihood that on the 5-point satiety scale the sugar-group increased by 1 point more than in the sugar-free group. We separately calculated increases in satiety from before intake to 1 minute after intake, and from before intake to 15 minutes after intake by adjusting for satiety prior to intake model 1.

In model 2 we additionally adjusted for caloric intake from snacks with the beverage, for gender and for BMI z score. Adjustments for gender and BMI z score served to correct for imbalances in randomization.

We used similar analyses to calculate differences between treatment groups in liking and wanting of the beverages. Calculations of liking and wanting were adjusted for gender and BMI z score at the start of the study.

We also calculated regression coefficients for effect modification by month of measurement. The sugar-free group always served as the reference group.

Therefore, odds ratios larger than 1 imply that the effect in the sugar group was larger than that in the sugar-free group, and vice versa. We also present arithmetic means of scores to show the differences between groups, and how the means changed with time. However, we did not perform statistical analyses of the arithmetic means because the outcomes were on an ordinal scale.

The participants were aged Baseline characteristics were similar for the two treatment groups, except that the sugar group had more girls, a lower mean BMI, and parents had on average achieved higher education levels Table 1.

Table 1. Baseline characteristics of participants. These percentages were similar for the two groups Table 2. Cross contamination and compliance were described previously[ 1 ]. Analysis of sucralose in urine showed that children in the sugar-group had not consumed sugar-free beverages.

The caloric intake from the snacks brought from home was 90 kcal in the sugar-free group and 84 kcal in the sugar group, mean SD Table 2 [ 18 , 19 ]. Table 2.

Medians with interquartile ranges of satiety, liking, wanting, and beverage- and snack intake, measured on a 5-point scale in children. In both groups, satiety was lowest before and highest 1 minute after beverage intake, and then decreased during the subsequent 14 minutes Table 2 ; Figure 3.

Sugar content of the beverages did not significantly affect satiety Table 3 ; Figure 4. At 1 minute after intake, the odds ratio for satiety was 0.

At 15 minutes, the effect was in the opposite direction, with an odds ratio of 1. Adjustments for caloric intake from the snack, for gender and for BMI z score at the start of the study had only minor effects on outcomes Table 3. Effect modification by timepoint, i. Satiety was scored from 1 not full at all to 5 very full.

Bars indicate the shift in satiety from before to after intake of the beverages. Panel A shows satiety 1 minute after intake; Panel B, 15 minutes after intake. An increase of 1 means any increase of 1 point on the 5-point scale. Table 3. Odds ratios for the effect of sugar-sweetened versus sugar-free beverages on satiety, liking and wanting across the duration of the trial.

Dashed lines, sugar group; solid lines, sugar-free group. T bars indicate one standard deviation. The children randomized to receive sugar-sweetened beverages liked these slightly more than those who received sugar-free beverages for 18 months; the odds ratio for a difference of 1 point on the liking scale was 1.

However, when the scores on the 5-point scale were averaged arithmetically the differences between the group means were small, and much smaller than the overall fall in liking over the course of the trial Figure 4.

Average liking fell by 1. This suggests that duration of consuming the drinks did not influence the differences in liking between groups. The children also wanted sugar-sweetened beverages more than sugar-free beverages; the odds ratio for a 1-point difference was 1.

We found that sugar-free and sugar-sweetened beverages produced similar degrees of satiety in a large population of children who consumed such beverages daily for 18 months. We previously reported that the children who consumed the sugar-free beverages accumulated less body fat than children who consumed sugar-sweetened beverages[ 1 ].

The present study suggests that this may be explained by similar levels of satiety. When we substituted sugar-free beverages for the sugar-containing drinks that children drank habitually, they apparently did not feel a need to eat more of other foods and drinks to compensate for the missing calories.

We tested satiety under real-life conditions, i. during the morning break at school when children consumed their beverage together with their usual snack.

We assume that satiety was determined by snack intake — mostly crackers, sweets, or fruits - , beverage volume, and caloric content of the drink.

Mean caloric intake from snacks and volume of drinks were the same between groups but the sugar-free drinks contained 26 g less sucrose.

We conclude that the sugar content of the drinks did not have a measurable effect on satiety. This finding is consistent with short term experiments in adults[ 7 , 8 , 9 , 10 , 11 ] that also found similar levels of satiety following sugar-containing and sugar-free beverages.

Effect modification by month of measurement for satiety 15 minutes after intake was marginally significant. This could indicate that sugar-sweetened beverages became more satiating as the trial proceeded.

However, this may have been a chance finding. We found that the children liked and wanted the sugar-sweetened beverage slightly more than the sugar-free beverage.

These differences persisted throughout the study even though overall liking and wanting of both types of beverage fell drastically with time. In contrast, short-term studies with pudding[ 20 ], or beverages[ 11 ] found similar ratings of pleasantness for aspartame-sweetened and sucrose-sweetened products.

However, beverages containing a blend of aspartame, acesulfame K and saccharin were rated lower in pleasantness than beverages containing sucrose[ 10 ]. Another study reported that cream cheese sweetened with aspartame had a more pleasant taste than cream cheese containing stevia or sucrose[ 21 ].

Thus the pleasantness of artificially sweetened products may be highly dependent on the type and mix of sweeteners used and on other aspects of product formulation.

According to the literature different neural pathways are involved in liking and wanting[ 12 ]. However, our data suggest that these concepts may be related since they produced similar results.

Future research is needed to examine whether wanting and liking indeed involve the same neural pathway or that our wanting scale lacked validity.

Liking and wanting of the trial drinks decreased markedly in both groups over the course of the trial. Similar declines have been reported in studies with solid foods over periods of 15 days to 6 months[ 22 , 23 , 24 ]. The decrease in liking and wanting agrees with our observation that most children who discontinued intake gave dislike of the beverage as their reason.

A year and a half is indeed a long time for a child to drink the same drink every day, and the variety of flavours that we offered was obviously not enough to overcome this. Sensory-specific satiety may have decreased liking and wanting over time[ 25 ].

Our study had several strengths. One is its long duration.
