Pro-inflammatory dietary intake as a risk factor for CVD in men: a 5-year longitudinal study

Convincing evidence has identified inflammation as an initiator of atherosclerosis, underpinning CVD. We investigated (i) whether dietary inflammation, as measured by the 'dietary inflammatory index (DII)', was predictive of 5-year CVD in men and (ii) its predictive ability compared with that of SFA intake alone. The sample consisted of 1363 men enrolled in the Geelong Osteoporosis Study who completed an FFQ at baseline (2001-2006) (excluding participants who were identified as having previous CVD). DII scores were computed from participants' reported intakes of carbohydrate, micronutrients and glycaemic load. DII scores were dichotomised into a pro-inflammatory diet (positive values) or an anti-inflammatory diet (negative values). The primary outcome was a formal diagnosis of CVD resulting in hospitalisation over the 5-year study period. In total, seventy-six events were observed during the 5-year follow-up period. Men with a pro-inflammatory diet at baseline were twice as likely to experience a CVD event over the study period (OR 2·07; 95 % CI 1·20, 3·55). This association held following adjustment for traditional CVD risk factors and total energy intake (adjusted OR 2·00; 95 % CI 1·03, 3·96). This effect appeared to be stronger with the inclusion of an age-by-DII score interaction. In contrast, SFA intake alone did not predict 5-year CVD events after adjustment for covariates (adjusted OR 1·40; 95 % CI 0·73, 2·70). We conclude that an association exists between a pro-inflammatory diet and CVD in Australian men. CVD clinical guidelines and public health recommendations may have to expand to include dietary patterns in the context of vascular inflammation.

Measurement of positive irrational beliefs (positive cognitive illusions)

The role of positive irrational beliefs (positive cognitive illusions) in mental health has been debated over several decades. The measurement of such beliefs has usually been through inferential assessment, which has been heavily criticised. This paper sought to establish a measure for the direct assessment of such beliefs and to assess their relationship to subjective wellbeing (SWB). Over two studies this new measure was found to have a factor structure consistent with its design, assessing self-enhancing beliefs, beliefs rejecting imperfection, overly optimistic beliefs, and irrational beliefs of control. When combined, these beliefs account for 17.6 % of the variance with SWB. This is driven largely by a higher order factor, which demonstrates a positive relationship to SWB. However, individually the different types of irrational beliefs demonstrate a variety of relationships with SWB. It is therefore concluded that positive irrational beliefs, when directly assessed, provide a greater depth of information than they do when assessed inferentially.

Linking positive psychology to offender supervision outcomes: The mediating role of psychological flexibility, general self-efficacy, optimism, and hope

This study examines the relationships between indicators of offender supervision outcomes and dimensions of positive psychological states (PPS). Results of a confirmatory factor analysis (CFA) revealed that the first-order positive psychology constructs converge to form a higher order construct of PPS which was inversely associated with supervision outcomes. Furthermore, the mediating effect of PPS on the relationship between criminogenic risk factors and all offender supervision outcome variables was statistically significant, suggesting that offenders with heightened PPS are likely to have fewer criminogenic risk factors and are less likely to be reported for technical violation, charged, reconvicted, and imprisoned. The implications of these findings for correctional theory, practice, and policy conclude the article.
