Objectives: Insufficient total fluid intake (TFI; sum of plain water and all other fluids) remain a significant public health issue in many developed countries for adults & children. The objective of our research is to assess the impact of an multi-component intervention based on Installation Theory, combining information (a web-based education program), affordances (free water bottles delivery at home), and social regulation (online forum) on plain water intake over a 12 months period in real life conditions, across targets and countries.
Methods: We have conducted 2 studies. In the first, 178 French women with mean TFI < 1,2L/d were enrolled in an 2-phase environmental intervention. In Phase 1 (4 weeks in duration), all participants received home deliveries of bottled water. In Phase 2 (4 months in duration), only participants who showed low water intake increase continued to receive home deliveries of bottled water and were also enrolled in the web-based information program. TFI was assessed at baseline, 2, 6 and 12 months.
In the second study, 334 preschool Polish children were allocated to 3 interventions: Control (no intervention), Information (INFO; online education sessions on water related health benefits and cues to action for parents), Information + Water Affordance (INFO+W; online education sessions and home delivery of water). After 3 months, half of the INFO and INFO+W subjects were randomly assigned to Social Regulation (+SOCIAL) (on-line discussion forum) or no further intervention (-SOCIAL). TFI of the children was recorded by the carers 6 times over a one-year period. Both studies assessed TFI with an online 7-day fluid-specific dietary record.
Results:
In the first study, plain water intake increased 1.5 times (+499 mL; P<0.001) in Phase 1. In Phase 2, participants who showed a low water intake increase in Phase 1 (0.5 times; +192 mL) increased their intake 1.5 times (+540 mL; P<0.001) compared with the baseline and reached the same intake level (P=0.58) as participants who exhibited a high water intake increase in Phase 1 (2.7 times; +598 mL; P<0.001). The significant 1.6 time increase in plain water intake (+ 538 mL; P<0.001) still occurred over 12 months in the total sample.
Over 1 year, all groups significantly increased water consumption by 3.0 to 7.8 times (+118 to +222 mL). The interventions had different effects. INFO+W+SOCIAL and INFO-SOCIAL generated the highest increase in plain water intake after one year compared to baseline, by 7.8 times (+216 mL) and 6.7 times (+222 mL) respectively, and both significantly exceeded the CONTROL (3.0 times, +118 mL), whilst the effect of INFO+W-SOCIAL (5.0 times, +158 mL) and INFO+SOCIAL (5.3 times, +198 mL) did not differ from that of the CONTROL. A secondary observation made was that all interventions also led to a decrease of sweetened beverages intake, again with INFO+W+SOCIAL generating the largest decrease (-27%; -172 mL).
Conclusions: Both studies indicated that a multi-component intervention can sustainably increase plain water intake in real life conditions among both adults and children.
