To assess the intake of nutrients in people with multiple sclerosis (pwMS) compared to a control population, and to assess the pro/ anti-inflammatory properties of nutrients/ foods and their relationships with fatigue and quality of life. This was a cross sectional study in which 2410 pwMS (686 men; 1721 women, 3 n/a, mean age 53 (11 years)) provided dietary data using a food frequency questionnaire that was hosted on the MS Register for a period of 3 months and this was compared to a cohort of 24,852 controls (11,250 male, 13,602 female, mean age 59 years). Consent was implied by anonymously filling out the questionnaire. A Wilcoxon test was used to compare intake between pwMS and controls, and a bivariate analyses followed by chi2 test were undertaken to identify significance and the strength of the relationship between pro/anti-inflammatory dietary factors and fatigue and EQ-5D. Compared to controls, all nutrients were significantly lower in the MS group (P

Healthy diet has been linked to better age-related physical functioning, but evidence on the relationship of overall diet quality in late midlife and clinically relevant measures of physical functioning in later life is limited. Research on potential sex differences in this relationship is scarce. The aim was to investigate the prospective association between overall diet quality, as assessed by the Healthy Eating Index-2015 at age 60-64y and measures of walking speed seven years later, among men and women from the Insight46, a neuroscience sub-study of the Medical Research Council National Survey of Health and Development. Diet was assessed at age 60-64y using five-day food diaries, from which total HEI-2015 was calculated. At age 69-71y, walking speed was estimated during four 10-meter walks at self-selected pace, using inertial measurement units. Multivariable linear regression models with sex as modifier, controlling for age, follow-up, lifestyle, health, social variables and physical performance were used. The final sample was 164 women and 167 men (n=331). Women had higher HEI-2015 scores and slower walking speed than men. A 10 point increase in HEI-2015 was associated with faster walking speed seven years later among women (B: 0.024, 95% CI: 0.006, 0.043), but not men. The association remained significant in the multivariable model (B: 0.021, 95% CI: 0.003, 0.040). In women in late midlife higher diet quality is associated with faster walking speed. A healthy diet in late midlife is likely to contribute towards better age-related physical capability and sex differences are likely to affect this relationship.

Beneficial effects of Mediterranean diet (MD) have been consistently documented. However, to fully understand the public health implications of MD adherence, an informative step is to quantify these effects in terms of survival time differences. The aim of this study was to evaluate the impact of MD on survival, presenting results in terms of differences in median age at death. We used data from 71,333 participants from a large population-based cohort of Swedish men and women, followed-up between January 1, 1998, and December 31, 2012. A total score of MD, ranging from 0 to 8, was calculated by including information on vegetables and fruits consumption, legumes and nuts, non-refined/high fiber grains, fermented dairy products, fish, red meat, use of olive oil/rapeseed oil, and moderate alcohol intake. Multivariable-adjusted differences in median age at death were estimated with Laplace regression and presented as a function of the MD score. During 15 years of follow-up we documented 14,697 deaths. We observed a linear dose–response association between the MD score and median age at death, with higher score associated with longer survival. The difference in median age at death between participants with the extreme scores (0 vs 8) of MD was up to 2 years (23 months, 95 % CI: 16–29). In this study we documented that adherence to MD may accrue benefits up to 2 years of longer survival.

Background. 
The joint impact of multiple healthy lifestyle factors on heart failure (HF) risk is unclear. We investigated the separate and collective associations of healthy lifestyle factors with HF incidence in 2 population-based prospective cohort studies.

Methods and Results. 
This study consisted of 33 966 men (Cohort of Swedish Men) and 30 713 women (Swedish Mammography Cohort) who were 45 to 83 years of age and free of HF and ischemic heart disease at baseline. A healthy lifestyle was defined as being a nonsmoker and physically active (≥150 min/wk), and having body mass index between 18.5 and 25 kg/m2 and a healthy diet (defined as adherence to a modified Mediterranean diet). Incident HF cases were ascertained by linkage with the Swedish National Patient Register and the Swedish Cause of Death Register. Cox proportional hazards regression was used to analyze the data. During13 years of follow-up, HF was diagnosed in 1488 men and 1096 women. Each healthy lifestyle factor was associated with a statistically significant lower risk of HF in both men and women, and the risk decreased with increasing number of healthy behaviors. The greatest reduction in HF risk was observed for combinations that included nonsmoking. Compared with men and women with none of the healthy lifestyle factors, the multivariable relative risks (95% confidence interval) of HF for those with all 4 healthy behaviors were 0.38 (0.28–0.53) in men and 0.28 (0.19–0.41) in women.

Conclusions. 
Adhering to a healthy lifestyle is associated with a substantially lower HF risk.

Aims.
We examined the hypothesis that high adherence to a Mediterranean diet reduces the risk of developing heart failure (HF) as well as the risk of death from HF.

Methods and results.
The study population comprised 37 308 men from the Cohort of Swedish Men who were free from cardiovascular disease at baseline. The modified Mediterranean diet (mMED) score was created from a self-administered food frequency questionnaire, based on consumption of presumed beneficial/detrimental foods, on a 0–8 scale. Incident HF events were ascertained by linkage to the Swedish National Patient and the Cause of Death Registers. Relative risks (RR) with 95% confidence intervals (CI), adjusted for potential confounders, were estimated by Cox proportional hazards regression models. We identified 146 deaths from HF and 1269 incident HF events over a median follow-up of 10.9 years (1998–2008). The mMED score was inversely associated with risk of HF (multivariable RR for the highest vs. lowest quartile 0.69, 95% CI 0.57, 0.83); the corresponding RR of HF mortality was 0.55 (95% CI 0.31, 0.98). The multivariable RR for every two-point increment in the mMED score was 0.85 (95% CI 0.78, 0.91) for incidence of HF and 0.78 (95% CI 0.62, 0.98) for mortality from HF, respectively.

Conclusions.
High adherence to a Mediterranean diet was associated with a lower risk of HF and mortality from HF in men. Further studies are needed to replicate these findings in other populations.

Background and aims.
The Mediterranean diet, which is palatable and easily achievable, has been associated with lower all-cause and cardiovascular disease (CVD) incidence and mortality. Data on heart failure (HF) and stroke types are lacking. The aim was to examine a Mediterranean diet in relation to incidence of myocardial infarction (MI), HF and stroke types in a Swedish prospective cohort.

Methods.
In a population-based cohort of 32,921 women, diet was assessed through a self-administered questionnaire. The modified Mediterranean diet (mMED) score was created based on high consumption of vegetables, fruits, legumes, nuts, whole grains, fermented dairy products, fish and monounsaturated fat, moderate intakes of alcohol and low consumption of red meat, on a 0–8 scale. Relative risks (RR) with 95% confidence intervals (CI), adjusted for potential confounders, were estimated by Cox proportional hazards regression models.

Results.
During 10 y of follow-up (1998–2008), 1109 MIs, 1648 HFs, 1270 ischemic strokes and 262 total hemorrhagic strokes were ascertained. A high adherence to the mMED score (6–8), compared to low, was associated with a lower risk of MI (RR: 0.74, 95% CI: 0.61–0.90, p = 0.003), HF (RR: 0.79, 95% CI: 0.68–0.93, p = 0.004) and ischemic stroke (RR: 0.78, 95% CI: 0.65–0.93, p = 0.007), but not hemorrhagic stroke (RR: 0.88, 95% CI: 0.61–1.29, p = 0.53).

Conclusions.
Better adherence to a Mediterranean diet was associated with lower risk of MI, HF and ischemic stroke. The Mediterranean diet is most likely to be beneficial in primary prevention of all major types of atherosclerosis-related CVD.
