The New Nordic Diet (NND) has induced weight loss in a 26-week controlled intervention. We aim to investigate whether high compliance and satisfaction can be maintained after the active intervention is discontinued thereby maintaining the health effects.
After 26 weeks of intervention with NND or Average Danish Diet (ADD), 147 participants (mean age 43 years and mean BMI 29.1 kg/m²) were followed for further 52 weeks. All participants were encouraged to follow NND but without further guidance. The study is registered with ClinicalTrials.gov, study id NCT01195610.
One hundred and ten participants (75%) completed the follow-up. Among participants previously randomised to NND (NND group), dietary compliance and satisfaction decreased from 4.3 to 3.0 and from 4.8 to 4.0, respectively (both p < 0.0001) (1-5 point scale). Among those originally randomised to ADD (ADD group), satisfaction with NND was significantly higher than with ADD during follow-up (3.3 vs. 2.5, p = 0.026). Weight losses during intervention of -6.2 kg and -3.0 kg were followed by regains of 4.6 kg (SE 0.5) and 1.1 kg (SE 0.7) for the NND group and ADD group, respectively [adjusted difference; mean (95 % CI): 1.8 kg (0.1-3.4), p = 0.041]. Across diet groups, every 1 score higher in compliance with NND was associated with 0.90 kg less body weight regain (p = 0.026) and those who increased physical activity regained 3.4 kg less compared to those who did not (p < 0.0001).
NND provides higher satisfaction, and body weight regain is reduced with higher compliance with NND and increased physical activity.
新北欧饮食（NND）在一项为期26周的对照干预中可导致体重减轻。我们旨在调查在停止积极干预后，高依从性和满意度是否能够得以维持，从而保持健康效果。
在用NND或丹麦平均饮食（ADD）进行26周干预后，对147名参与者（平均年龄43岁，平均BMI 29.1kg/m²）进行了为期52周的随访。鼓励所有参与者遵循NND，但不再给予进一步指导。该研究已在ClinicalTrials.gov注册，研究编号为NCT01195610。
110名参与者（75%）完成了随访。在之前被随机分配到NND组（NND组）的参与者中，饮食依从性和满意度分别从4.3降至3.0，从4.8降至4.0（均p<0.0001）（1 - 5分制）。在最初被随机分配到ADD组（ADD组）的参与者中，随访期间对NND的满意度显著高于对ADD的满意度（3.3对2.5，p = 0.026）。NND组和ADD组在干预期间体重分别减轻了6.2kg和3.0kg，之后分别反弹了4.6kg（标准误0.5）和1.1kg（标准误0.7）[校正差异；均值（95%置信区间）：1.8kg（0.1 - 3.4），p = 0.041]。在所有饮食组中，NND依从性每高1分，体重反弹就减少0.90kg（p = 0.026），与未增加身体活动者相比，增加身体活动者体重反弹减少3.4kg（p<0.0001）。
NND带来更高的满意度，且随着对NND更高的依从性和增加身体活动，体重反弹减少。
