Objective: To study the long-term effects of weight reduction, quality of life and sense of coherence in a primary health care (PHC)-based programme with two different intensities. Design: Prospective two-armed randomised intervention. Setting: Three PHC centres in south west of Sweden. Subjects: In total, 289 women and men aged 40-65 years with a BMI of 28-35 were recruited for a two-year weight-reduction programme. Participants were randomized to high-intensity or lowintensity groups. Blood samples, physical measurements and questionnaires were analysed. Participants received cookbooks and dietary lectures. The high-intensity group also received Motivational interviewing (MI), dietary advice on prescription (DAP-advice), a grocery store lecture, a website and weekly e-mails. Main outcome measures: Weight, quality of life, risks and health factors. Results: In total, 182 (64%) participants completed the 2-year follow-up. The total sample reduced their weight by 1 kg (p ¼ 0.006). No significant differences regarding weight were found between the groups. Anxiety/depression decreased in EQ5-D (p ¼ 0.021), EQ5-D VAS (p ¼ 0.002) and SOC (p ¼ 0.042). Between the groups, there were significant differences in EQ5-D usual activities (p ¼ 0.004), anxiety/depression (p ¼ 0.013), pain/discomfort (p ¼ 0.041), fruit and vegetables (p ¼ 0.005), HLV anxiety (p ¼ 0.005), and visits to nurses (p ¼ 0.012). Conclusion: The total population lost weight, and the high-intensity and low-intensity programmes did not result in significant differences in terms of weight. The high-intensity programme reported health benefits linked to lower levels of anxiety and depression, increased activity and intake of greens and reduced visits to physicians and nurses. KEY POINTS Both groups had a consisting weight-reduction after two years. High intensity did not lead to a significant difference in weight reduction between the groups. The high-intensity group reported more health effects, such as better quality of life, reduced anxiety, and increased greenery intake. It is unknown how much support patients in a weight-reduction programme in PHC require to succeed with weight loss and a healthy lifestyle ARTICLE HISTORY
