  abstract  = {Background Quality of life is an important concept in the field of health, which can be influenced by various lifestyle factors. The objective was to test if a community-based lifestyle programme would beneficially affect the health-related quality of life of German women. Methods The controlled intervention study had a total duration of 24 months. Quality of life (EQ-5D-3L), anthropometrics, vital and blood parameters as well as diagnosed diseases and health economic parameters were collected at baseline (t0), after 10 weeks (t1) and after 6 months (t2). For the intervention group (n = 65) a 10-week intensive lifestyle programme followed by monthly alumni meetings were conducted. The intensive phase consisted of 14 consecutive seminars about a healthy lifestyle, which focused on a plant-based diet, physical activity, stress management and community support. The control group (n = 35) received no intervention. Results The first descriptive health profile results of the subgroup analysis showed that 59\% women of the intervention group at t0 (t1: 37\%; t2: 48\%) and 60\% of the control group at t0 (t1: 54\%; t2: 49\%) reported problems in at least one of the EQ-5D dimensions (mobility, selfcare, activities, pain, and anxiety). A significant difference in EQ VAS change between women in intervention (7,15 [95\% CI 4,32; 9,98]; EQ VAS t0: 75,35 [SD 13,71]) and control group (-2,63 [95\% CI -5,40; 0,15]; EQ VAS t0: 78,80 [SD 18,51]) from t0 to t1 was observed (p < 001; adjusted for baseline). No significant differences in mean EQ VAS change from t0 to t2 and in mean EQ-5D index change from t0 to t1 and t0 to t2 between the groups were observed (p > 0,05; adjusted for baseline). Conclusions The preliminary results suggest that the lifestyle intervention programme can have a positive short-time effect on some aspects of quality of life, such as the health profile and EQ VAS. However, the long-term results will be shown in the future. Key messages - A healthy lifestyle can affect the quality of life in a positive way. - The community-based lifestyle programme had a short-time influence on the descriptive health profile and EQ VAS of German women, whereby the EQ index didńt change significantly between the groups.},

  abstract  = {Background Common carotid intima-media thickness (ccIMT) is an established risk marker for cardiovascular events, including myocardial infarction and stroke, which are of high public health relevance. While a higher fruit intake is generally considered beneficial for cardiovascular health, recent studies have shown that a fruit intake of > 2 portions per day may be harmful. Therefore, we tested if there is an association between categories of fruit intake and mean ccIMT. Methods We conducted an exploratory, non-prespecified, cross-sectional analysis of baseline values of 167 mostly middle-aged participants of a controlled lifestyle intervention, recruited from the general population in rural northwest Germany (male: n = 58; female: n = 109). Fruit intake was classified into low (<1 portion of fruit/day), intermediate (1-2 portions of fruit/day), and high (>2 portions of fruit/day). Mean ccIMT was measured in accordance with the Mannheim consensus. Between-group differences in mean ccIMT were assessed with analysis of covariance. Results Mean age was 57.3 ± 0.7 years (mean ± SEM). Mean fruit intake was 1.6 ± 0.1 portions/day. Average mean ccIMT was 0.679 ± 0.010 mm. There was a significant difference in mean ccIMT between subjects with low (0.676 ± 0.020 mm; n = 50), intermediate (0.653 ± 0.014 mm; n = 72), and high fruit intake (0.724 ± 0.019 mm; n = 45; p = 0.016). But this difference was attenuated when adjusting for age, sex, and homocysteine (p = 0.418). Conclusions We found only a non-significant association between consuming >2 portions of fruit per day and ccIMT. Thus, our study could not confirm a negative effect of fruit intake on ccIMT. Age, sex, and homocysteine may confound this association. Key messages Current recommendations of 2 portions of fruit per day seem adequate and do not negatively influence carotid intima-media thickness. Future studies should address confounding of the association between fruit intake and cardiovascular risk markers.},

  abstract  = {Common carotid intima-media thickness (ccIMT) progression is a risk marker for cardiovascular disease (CVD), whereas healthy lifestyle habits are associated with lower ccIMT. The objective of the present study was to test whether a healthy lifestyle intervention can beneficially affect ccIMT progression. A community-based non-randomised, controlled lifestyle intervention was conducted, focusing on a predominantly plant-based diet (strongest emphasis), physical activity, stress management and social health. Assessments of ccIMT were made at baseline, 6 months and 1 year. Participants had an average age of 57 years and were recruited from the general population in rural northwest Germany (intervention: n 114; control: n 87). From baseline to 1 year, mean ccIMT significantly increased in both the intervention (0⋅026 [95 \% CI 0⋅012, 0⋅039] mm) and control group (0⋅045 [95 \% CI 0⋅033, 0⋅056] mm). The 1-year trajectory of mean ccIMT was lower in the intervention group (P = 0⋅022; adjusted for baseline). In a subgroup analysis with participants with high baseline mean ccIMT (≥0⋅800 mm), mean ccIMT non-significantly decreased in the intervention group (-0⋅016 [95 \% CI -0⋅050, 0⋅017] mm; n 18) and significantly increased in the control group (0⋅065 [95 \% CI 0⋅033, 0⋅096] mm; n 12). In the subgroup, the 1-year trajectory of mean ccIMT was significantly lower in the intervention group (between-group difference: -0⋅051 [95 \% CI -0⋅075, -0⋅027] mm; P < 0⋅001; adjusted for baseline). The results indicate that healthy lifestyle changes may beneficially affect ccIMT within 1 year, particularly if baseline ccIMT is high.},
