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.

‘We just call them people’: positive regard as a dimension of culture in group homes for people with severe intellectual disability

BackgroundA dimension of the culture in group homes is staff regard for residents. In underperforming group homes, staff regard residents as being not ‘like us’ (Bigby, Knox, Beadle-Brown, Clement & Mansell, 2012). We hypothesized the opposite pole of this dimension, in higher performing group homes, would be that staff regard residents positively.MethodThree in-depth qualitative case studies were conducted in higher performing group homes using participant observation, interviews and document review.ResultsConsistent pattern of staff practices and talk, as well as artefacts, demonstrated staff had a positive regard for residents, who were seen as being ‘like us’. Explicit and continuing attention was given to sustaining positive regard for residents in everyday staff practices and to turning abstract values into concrete realities.ConclusionsThis positive cultural norm was established, operationalized and embedded through structures, such as a formal policy about language, and processes such as peer monitoring and practice leadership.
