To prevent and reduce non-communicable diseases, the Norwegian Directorate of Health encourages Healthy Life Centres (HLCs) in all municipalities.
This study investigates whether the behaviour change interventions at HLCs positively affected participants' diet and to evaluate predictors for healthy and unhealthy eating. Our data are part of the Norwegian Healthy Life Centre Study, a 6-month, pragmatic randomised controlled trial (RCT).
Totally, 118 participants ≥18 years old were randomised to an intervention group (n 57), or a waiting list (control group) (n 61). Eighty-six participants met at the 6 months follow-up visit. We merged the participants to one cohort for predictor analyses, using linear regressions.
The RCT of the HLCs' interventions had no effect on healthy and unhealthy eating 6 months after baseline compared with controls. A short, additional healthy eating education programme produced a modest, statistically significant improvement in healthy eating compared with controls. This did not, however, reduce unhealthy eating. Higher income predicted unhealthier eating over time. Increasing body mass index and impaired physical functioning also led to an increase in unhealthy eating. Healthy eating at 6 months was predicted by self-rated health (SRH), vitality and life satisfaction, and hampered by musculo-skeletal challenges and impaired self-esteem (SE). SRH impacted improvement in healthy eating during the 6 months. The effect of interventions on healthier eating may be improved by an emphasis on developing positive self-concepts like better SRH, vitality, life satisfaction, and SE.
为了预防和减少非传染性疾病，挪威卫生局鼓励所有市建立健康生活中心。
本研究旨在调查健康生活中心的行为改变干预措施是否对参与者的饮食产生积极影响，并评估健康和不健康饮食的预测因素。我们的数据是挪威健康生活中心研究的一部分，这是一项为期 6 个月的实用随机对照试验（RCT）。
共有 118 名年龄在 18 岁及以上的参与者被随机分配到干预组（n=57）或候补名单（对照组）（n=61）。86 名参与者在 6 个月的随访时参加了研究。我们将参与者合并到一个队列中进行预测因素分析，使用线性回归。
与对照组相比，健康生活中心干预措施的 RCT 在基线后 6 个月对健康和不健康饮食没有影响。一个简短的额外健康饮食教育计划在健康饮食方面产生了适度的、统计学上显著的改善，但并没有减少不健康饮食。较高的收入预测随着时间的推移会导致不健康的饮食。体重指数增加和身体功能受损也会导致不健康饮食的增加。6 个月时的健康饮食由自我报告的健康状况（SRH）、活力和生活满意度预测，而肌肉骨骼挑战和自尊受损（SE）则会阻碍健康饮食。SRH 对 6 个月内健康饮食的改善有影响。通过强调发展积极的自我概念，如更好的 SRH、活力、生活满意度和 SE，干预措施对更健康饮食的效果可能会得到改善。
